    Description

    Technical Field



    [0001] The present invention relates to the technical field of elevator governors, and in particular, to a governor for a car mounted elevator and an elevator system having the same.

    Background Art



    [0002] As technologies for elevator governor assemblies develop, new Car Mounted Governor (CMG) assemblies are more widely applied. Compared with the conventional design in which a governor is mounted at the top of a hoistway in a governor assembly with or without a machine room, a CMG is mounted on an elevator car and moves vertically along with the car. The CMG has a more compact structure and is suitable for a limited hoistway space. The Patent US2013/0098711A1 published by Aguado et al. on April 25, 2013 disclosed a CMG. When the rotating speed of a sheave exceeds a first limit value, the governor assembly invented by Aguado et al. can expand a centrifugal block support rotating together with the sheave, to trigger an electrical switch to cut off the electricity. When the rotating speed of the sheave exceeds a second limit value greater than the first limit value, a roller on the inner side of a connecting rod of a centrifugal mechanism of the governor assembly will be jointed to a core ring, such that the core ring is driven by the sheave and triggers a safety apparatus associated with the core ring, and therefore the safety apparatus can generate mechanical friction with a rail to brake the car. In such a CMG, the governor assembly further includes a remote triggering apparatus. The remote triggering apparatus can be controlled actively to act on the centrifugal mechanism, such that the governor assembly can be triggered actively even that the car is not overspeed, so as to be used in, e.g., a test. The existing remote triggering apparatus is mainly composed of an electromagnet, and a tail end of a column of the electromagnet directly acts on a plastic-made centrifugal block support of the centrifugal mechanism.

    [0003] In previous applications, the CMGs are generally applied to low-speed elevators. The Chinese Utility Model Patent No. ZL201621141734.2 filed by the Otis Elevator Company on October 20, 2016 and entitled "REMOTE TRIGGERING APPARATUS, GOVERNOR ASSEMBLY AND ELEVATOR" disclosed a remote triggering apparatus. A contact having a smooth transitional surface is adopted in the remote triggering apparatus, such that a CMG is tried to be applied to a high-speed elevator.

    Detailed description



    [0008] It is easily understood that those of ordinary skill in the art can propose various interchangeable structural modes and implementation manners without departing from the scope of the present invention as defined by the claims. Therefore, the following specific implementation manners and accompanying drawings are exemplary illustrations of the technical solutions of the present invention and should not be considered as all of the present invention or considered as definitions or limitations to the technical solutions of the present invention.

    [0009] Orientation terms such as upper, lower, left, right, front, rear, front, back, top, and bottom that are or might be mentioned in the specification are used for definition with respect to constructions shown in the accompanying drawings, and they are relative concepts and are possibly changed correspondingly according to their different positions and different use states. Therefore, these or other orientation terms should not be construed as limitative terms.

    [0010] FIG. 1 and FIG. 2 show schematic views of a governor assembly according to an embodiment. The governor assembly mainly includes a stationary shaft 9, a sheave 11, a core ring 8, a lock mechanism 20, a centrifugal mechanism 30, a remote triggering apparatus 70, an electrical safety switch 80, and so on. As more clearly shown in FIG. 2, the sheave 11 is arranged on the stationary shaft 9 and is rotatable on the stationary shaft 9. For example, the sheave 11 can be arranged on the stationary shaft 9 through two ball bearings 91 and 92. A sheave groove 110 is disposed on the periphery of the sheave 11 such that the sheave 11 can rotate as the car moves, and the rotating speed and direction of the sheave 11 is related to the movement of the car. The core ring 8 is arranged on one side of the sheave 11 on the stationary shaft 9, that is, the front side of the sheave 11 in the drawing. In some embodiments, the core ring 8 has a recess to partially enclose a front inner ring 13 of the sheave. The front side of the core ring 8 can be associated with a safety apparatus. For example, the core ring 8 can be connected to a rocker arm (not shown) through bolts 81 and 82, and when the core ring 8 rotates, the rocker arm can be driven, and the safety apparatus is started. In some embodiments, the safety apparatus can be an apparatus such as safety tongs capable of being frictionally jointed to a rail of the elevator to brake the car of the elevator. The centrifugal mechanism 30 can be disposed on the front side of the sheave 11, and a specific structure of the centrifugal mechanism is described in detail in the following. As the speed of the elevator (corresponding to the rotating speed of the sheave) reaches a first predetermined value, the centrifugal mechanism will be expanded due to the centrifugal force and an outer ring of the centrifugal mechanism will contact the electrical safety switch 80, so as to cut off the power supply to an elevator traction system to brake the elevator. If the speed of the elevator is not reduced but is increased continuously and reaches a second predetermined value, the lock mechanism 20 of the governor assembly functions, that is, a roller 24 of the lock mechanism 20 is jointed to the core ring 8, such that the roller 24 drives the core ring 8 to rotate to start the mounting apparatus, thus braking the elevator mechanically. The specific structure of the lock mechanism 20 will also be described in detail in the following. In addition, the governor assembly further provides a remote triggering apparatus 70. The remote triggering apparatus 70 can trigger the governor even that the elevator is not overspeed, so as to perform a test, for example, testing whether the governor and/or the mounting apparatus work/works normally. The triggering apparatus 70 can be an electromagnetic switch based on the electromagnetic effect and has an extension portion 71 that can perform linear displacement.

    [0011] The specific structure of the lock mechanism is described in detail now with reference to FIG. 3 to FIG. 7. FIG. 7 more clearly shows an individual lock mechanism 20. In the embodiment shown in the drawings, the lock mechanism 20 includes three rockers 21. In an alternative embodiment, the number of the rockers of the lock mechanism is variable. The three rockers 21 each include a first end 211 that is pivotably connected to a corresponding position on the sheave 11 and a second end 212 that is connected to the roller 24. The three rockers 21 are connected by connecting rods 26 such that the three rockers 21 are synchronized. Each rocker 21 can switch, through pivoting around the first end 211, between a first position where the roller 24 is separated from the core ring 8 and a second position where the roller 24 is jointed to the core ring 8. In the second position, the roller 24 at the second end of each rocker 21 that rotates along with the sheave 11 drives the core ring 8 to rotate to start the safety apparatus. In some embodiments, the first end 211 of the rocker 21 is pivotably connected to the sheave 11 through a pin 22 and a reset spring 23. In the embodiment shown in the drawing, the three rockers 21 are distributed uniformly along the circumference of the sheave, and the first ends 211 of the rockers 21 are pivoted to different positions of the same circumference of the sheave 11, that is, the connection positions of the first ends 211 of the rockers 21 and the sheave are distributed uniformly along a circumference with the center of circle of the sheave as the center of circle and a specific distance R as the radius.

    [0012] In a preferred embodiment, each rocker 21 can be Y-shaped. The Y-shaped rocker 21 has three end portions 213, and a third end portion 213' of an adjacent rocker 21 is connected to the second end 212 of the rocker through a connecting rod 26. In an alternative embodiment, the rocker 21 can also have other shapes, and the connecting rod 26 can also connect adjacent rockers 21 in other suitable manners. Further, as more clearly shown in the embodiment of FIG. 4, in some embodiments, the second end 212 of the rocker 21 is connected to the roller 24 through a support shaft 25. In an alternative embodiment, the second end of the rocker 21 can also be connected to the roller 24 directly or through other structures. Referring to FIG. 4 to FIG. 6, in some embodiments, the first end 211 of the rocker 21 is connected to the rear side of the sheave 11 through the pin 22 and the reset spring 23, the second end 212 of the rocker 21 is connected to the support shaft 25, the support shaft 25 passes through an opening 12 on the sheave 11 and extends to the front side of the sheave 11, and the roller 24 is mounted on the support shaft 25 in a position aligned with the core ring 8. The core ring 8 is not shown in these views and is located on a radial outer side of the front inner ring 13 of the sheave in FIG. 5. In some embodiments, the support shaft 25 has a first end 251 located at the front side of the sheave and a second end 252 located at the rear side of the sheave. In some embodiments, a second end 26 of the connecting rod 26 passes through the opening 12 on the sheave 11 at the third end 213 of the rocker 21, extends from the front side of the sheave 11, and is connected to the second end 212 of the adjacent rocker 21 at a first end 261 of the connecting rod 26, specifically connected to a position in the middle of the support shaft 25 and close to the roller 24. As clearly shown in the cross-sectional view in FIG. 4, in some specific embodiments, the first end 211 of the rocker 21 is connected to the rear side of the sheave 11 through the pin 22, the second end 212 of the rocker 21 has an opening, and the support shaft 25 is inserted into the opening of the second end 212 of the rocker 21. The first end 251 of the support shaft 25 has a slightly expanded diameter and is located at the rear side of the sheave 11. A lining 260 is subsequently connected to the support shaft 25, a second end 261' of the connecting rod 26 follows the lining 260, and the roller 24 follows the second end 261' of the connecting rod 26. The roller 24 is positioned on the support shaft 25 by a card 257, and the second end 252 of the support shaft 25 is exposed and located at the front side of the sheave 11. In addition, the third end 213 of the rocker 21 is connected to a shaft 263 which is further connected to the second end 262 of the connecting rod 26, and the second end 262 of the connecting rod is positioned by a card 264. Referring to FIG. 3, the lock mechanism 20 according to each embodiment is entirely mounted to the sheave 11, and each rocker of the lock mechanism 20 can rotate about a respective pivotal axis, such that the overall lock mechanism 20 can rotate relative to the sheave 11.

    [0013] The centrifugal mechanism 30 according to an embodiment of the present invention is described below with reference to FIG. 8 to FIG. 11. The centrifugal mechanism 30 includes a plurality of centrifugal block supports 31 that are pivotably fixed on the front side of the sheave 11. FIG. 9 shows a pivotal center 311 of the plurality of centrifugal block supports 31. The plurality of centrifugal block supports 31 are provided with centrifugal blocks 32. Adjacent centrifugal block supports 31 are connected by a centrifugal mechanism connecting rod 35. Specifically, as shown in FIG. 9, a first end 351 of the centrifugal mechanism connecting rod 35 is connected to an end portion of a centrifugal block support 31', and a second end 352 of the centrifugal mechanism connecting rod 35 is connected to an end portion of an adjacent centrifugal block support 31. The centrifugal mechanism further includes a retaining mechanism for retaining the plurality of centrifugal block supports at a contraction position, e.g., a tension spring 33 between the centrifugal block supports as shown in the drawings, or a magnetism-based retaining mechanism may be adopted alternatively. The centrifugal mechanism 30 rotates as the sheave 11 rotates, and when the rotating speed of the sheave 11 is increased, the centrifugal mechanism 30 has a tend towards an expansion position shown in FIG. 10 under the drive of the centrifugal force. In an expansion process of the centrifugal mechanism 30, the centrifugal block support 31 will contact and trigger the electrical safety switch 80. A specific embodiment of the centrifugal mechanism 30 is shown in FIG. 8 to FIG. 11; however, in alternative solutions, the lock mechanism 20 of the present invention can be combined in use with any centrifugal mechanisms 30 including existing.

    [0014] In some embodiments, the lock mechanism 20 of the present invention is correlated with the centrifugal mechanism 30. In some embodiments, the support shaft 25 of the lock mechanism 20 is connected to the centrifugal mechanism 30, such that the centrifugal mechanism 30 can drive the lock mechanism 20 to rotate. In some embodiments, the second end 252 of the support shaft 25 of the lock mechanism is connected to the centrifugal mechanism 30, e.g., the connecting rod 35 of the centrifugal mechanism 30. Alternatively, the lock mechanism 20 can also be related to the centrifugal mechanism 30 in other manners. For example, the lock mechanism 20 can be connected to the centrifugal mechanism 30 by means of another position such as the second end 212, or the support shaft 25 can also be connected to another position on the centrifugal mechanism 30, e.g., on the centrifugal block support, as long as the centrifugal mechanism 30 is coupled to the lock mechanism 20 in the expansion process and drives the roller 24 of the lock mechanism 20 to be jointed to the core ring 8. In some embodiments, a notch 353 is formed on the connecting rod 35 of the centrifugal mechanism 30, and the second end 252 of the support shaft 25 is fitted in the notch 353 of the centrifugal mechanism connecting rod 35 and is movable along the notch 353. In some embodiments, the notch 353 of the centrifugal mechanism connecting rod 35 has an arc shape corresponding to a track of the second end 252 of the support shaft 25 when the rocker 21 pivots. That is, the notch 353 is corresponding to a track of the second end 252 of the support shaft 25 when the rocker 21 pivots about the shaft 22. Definitely, in an alternative embodiment, the notch 353 can be opened to at least include the track, for example, the notch can be opened to be longer and wider than the track, or the like. In some embodiments, an initial position 354 of the notch 353 on the centrifugal mechanism connecting rod 35 is adjustable. FIG. 11 shows a method of simply adjusting the initial position 354 of the notch 353. In some embodiments, a first end of the notch 353 of the centrifugal mechanism corresponding to the initial position is provided with a bolt hole 361, and a bolt 37 is fitted into the bolt hole and can be extended into the notch. Moreover, the initial position 354 of the notch 353 is adjusted by the length of the bolt 37 inserted into the notch 353. Optionally, a nut 372 can be used to position the bolt 37. Definitely, in an alternative embodiment, the initial position 354 of the notch 353 can also be adjusted by adopting any other suitable method, for example, adding any obstacle at one end of the notch 353, such as inserting a rubber plug at one end of the notch 353.

    [0015] How the governor assembly of the present invention is triggered is understood with reference to FIG. 12 and FIG. 13. In FIG. 12, a clockwise rotation direction of the sheave corresponds to the downward direction of the elevator car. FIG. 12 shows that the governor assembly is not overspeed and the centrifugal mechanism 30 is at a contraction position. In the drawing, the centrifugal block support 31 at the left side is drawn with dotted lines such that its internal structure is visible. The second end 252 of the support shaft 25 is located in the notch 353 of the centrifugal mechanism connecting rod 35 and is located at the initial position of the notch 353 and abuts against the end portion of the bolt 371. The initial position of the notch 353 can be adjusted by tightening or loosening the bolt 371. In FIG. 12, the position of the core ring 8 is drawn with dotted lines. When the centrifugal mechanism 30 is in the contraction position, the rocker 21 is located in the first position where the roller 24 is separated from the core ring 8. When the rotating speed of the sheave 11 exceeds a first predetermined value, the centrifugal block support 31 of the centrifugal mechanism 30 will trigger the electrical safety switch 80. When the rotating speed of the sheave 11 exceeds a second predetermined value, the centrifugal block 32 of the centrifugal mechanism 30 is expanded to the expansion position shown in FIG. 13 under the drive of the centrifugal force C. The notch 353 of the connecting rod 35 of the centrifugal mechanism 30 drives the second end 252 of the support shaft 25 in the notch, so as to drive the rocker 21 to pivot from the first position where the roller 24 is separated from the core ring 8 to the second position where the roller 24 is jointed to the core ring 8. As shown in FIG. 13, the rocker 21 has been pivoted to the second position, and the roller 24 has been jointed to the core ring 8 and will drive the core ring 8, thereby triggering the safety apparatus.

    [0016] How to actively trigger the governor assembly of the present invention is understood with reference to FIG. 14 and FIG. 15. When remote triggering is required, the extension portion 71 of the remote triggering apparatus 70 can extend along an S direction in response to, e.g., a control switch of an operating room, and interferes with the lock mechanism 20, such that the plurality of rockers 21 are pivoted to the second position where the roller 24 is jointed to the core ring 8. In some embodiments, the extension portion 71 of the remote triggering apparatus 70 acts on the support shaft 25 of the lock mechanism 20. In some embodiments, the extension portion 71 of the remote triggering apparatus 70 is located at the rear side of the sheave and acts on the first end 251 of the support shaft 25. Definitely, it is alternative that the remote triggering apparatus can also act on another part of the lock mechanism 20 or another part of the support shaft 25. As shown in FIG. 15, as the sheave 11 rotates clockwise, the extension portion 71 of the remote triggering apparatus 70 toggles the first end 251 of the support shaft 25, such that the rocker 21 is pivoted along the shaft 22 to the second position where the roller 24 is jointed to the core ring 8, thereby actively triggering the governor assembly. During rotation of the rocker 21, the second end 252 of the support shaft 25 moves along the notch 353 of the centrifugal mechanism connecting rod 35, such that the lock mechanism 20 rotates independent of the centrifugal mechanism 30, drives the core ring 8, and starts the safety apparatus.

    [0017] According to another aspect of the present invention, an elevator system having the governor assembly according to the embodiments of the present invention is further provided.

    [0018] Advantages of the governor assembly and the elevator system of the present invention include, but are not limited to:
    Compared with the prior art in which the roller is directly connected to the connecting rod of the centrifugal mechanism 30, the present invention adopts an independent lock mechanism 20 and an independent centrifugal mechanism 30. On one hand, the position of the lock mechanism 20 relative to the centrifugal mechanism 30 can be adjusted by adjusting the initial position of the notch 353, thereby adjusting the second predetermined value of the mechanical triggering speed of the governor. Standards in the art have restrict specifications on a ratio of the first predetermined value to the second predetermined value of the triggering speed of the governor, and therefore, extremely high requirements have been put forward for the manufacturing precision (such as tolerance) of parts of the governor. Using the governor assembly of the present application can reduce the requirement on the part precision, and the ratio of the first predetermined value to the second predetermined value is implemented through subsequent adjustment, thereby meeting the standards.

    [0019] On the other hand, compared with the technical solution in the prior art in which the remote triggering apparatus directly acts on the connecting rod of the centrifugal mechanism 30, the remote triggering apparatus of the present invention acts on the lock mechanism 20. When the governor assembly is actively triggered through the remote triggering apparatus, as the lock mechanism 20 is pivotable independent of the centrifugal mechanism 30 and the weight and the rotational inertia of the lock mechanism 20 are small, no great impact will be generated when the remote triggering apparatus contacts the lock mechanism 20, e.g., the first end 251 of the support shaft 25. Therefore, the governor assembly according to the present invention can be applied to a high-speed elevator system. In the high-speed elevator system, the centrifugal mechanism has a large rotational inertia, and if the remote triggering apparatus directly acts on the centrifugal mechanism, the plastic-made centrifugal mechanism may be broken, and a core column of the electromagnetic switch may be shocked or even retracted.

    [0020] Finally, in the governor assembly of the present invention, the lock mechanism 20 and the centrifugal mechanism 30 are skillfully arranged on two sides of the sheave and are correlated through the opening of the sheave, such that the whole governor assembly is compact in structure.

    [0021] The specific embodiments described above are merely used to describe the principles of the present invention more clearly, and components are clearly shown or described such that the principles of the present invention are more easily comprehensible. Those skilled in the art can easily make various modifications or changes on the present invention without departing from the scope of the present invention. Therefore, it should be understood that these modifications or changes should all be encompassed in the patent protection scope of the present invention.
