Description

[0001] This invention mainly concerns the systems of crane elevators, moving along the rail, attached to the external side of the construction, and transport facilities for the transportation and mounting/dismounting of elevators.

[0002] There is a known solution of "Lift System, Lift System Rail, and the Method of Reaching the Construction Surface" (patent EAPO 008405 of 13.09.04, class B66B 9/00, A62B 1/02, B66B 7/02), wherein the lift crane system is attached to the external side of the construction. The specified system includes a lifting unit, which enters in contact with the rail for moving the lifting unit along the rail, attached to the construction structure. Thus, a boom crane is mounted on the lifting unit, which has a rotating and rotary mechanism to support one end of the boom that comprises a telescopic section for reaching any point on the construction or under it. Besides, the lift crane system has a transport facility with the mechanism for forwarding and returning the lifting unit, for its holding near the rail for the fixation or releasing. The indicated system can be used for construction operation and maintenance of buildings.

[0003] The construction of this system does not allow to secure fixation of the lifting unit in the construction structure for the increase of load capacity of the boom crane, as well as mounting of the lifting unit on the transport facility for the possibility of boom crane operation on the transport facility, and mounting of the lifting unit on the building surface for the possibility of boom crane operation near the construction, but separately from the transport facility.

[0004] The present invention is directed to solve the technical task on the fixation of the lifting unit in the construction structure for the increase of load capacity of the boom crane, as well as mounting of the lifting unit on the transport facility for the possibility of boom crane operation on the transport facility, and mounting of the lifting unit on the building surface for the possibility of boom crane operation near the construction, but separately from the transport facility.

[0005] The technical result, achieved at the use of this invention, is the operational capability extension of the lift crane system.

[0006] The indicated technical result is achieved due to the fact that the lift-crane system is adapted to be connected to the external side of a construction, and contains at least one lifting unit engaged with at least one rail for moving the lifting unit along the rail attached to the structure of the construction; a boom crane including a rotating mechanism and a rotary mechanism for bearing one end of the boom that comprises at least one telescopic section (one or more) for reaching any point on the construction or above the construction; a transport facility with a mechanism for forwarding and returning the lifting unit for maintaining said unit in the vicinity of the rail for securing it to or releasing it from the latter; which differs by the fact that the lifting unit comprises beating members for attaching the lifting unit to the structure of the construction in order to increase the load capacity of the boom crane during the operation thereof on the construction, the transport facility comprises a nominal location for mounting the lifting unit on the transport facility so that the boom crane can operate directly on the transport facility, and the building surface of the construction includes at least one nominal location for mounting the lifting unit on the building surface so that the boom crane can operate in the vicinity of the construction and independently from the transport means.

[0007] In the particular embodiment, the supporters, securing the attachment of the lifting unit to the construction structure are made as steel dismountable beams, interacting with metal sheaths of the lifting unit and the construction.

[0008] In the particular embodiment, fixation of steel dismountable beams in metal sheaths of the lifting unit and the construction is made by screw couplings, interacting with the holes, made in steel dismountable beams, and in metal sheaths of the lifting unit and the construction.

[0009] In the particular embodiment, the nominal location of transport facility for the mounting of the lifting unit is made in a form of metal horizontal location, the surface of which corresponds to the surface of the lower surface of the lifting unit.

[0010] In the particular embodiment, mounting of the lifting unit on the metal horizontal location of nominal transport facility location is performed by means of screw elements, which interact with the holes, made in the lower surface of the lifting unit, and metal horizontal location of nominal transport facility site.

[0011] In the particular embodiment, the transport facility has a nominal location for the fixation of a balance beam.

[0012] In the particular embodiment, the nominal location of construction building surface for the mounting of the lifting unit is made in a form of metal horizontal location, the surface of which corresponds to the surface of the lower surface of the lifting unit.

[0013] In the particular embodiment, mounting of the lifting unit on the metal horizontal location of nominal building surface location is performed by means of screw elements, which interact with the holes, made in the lower surface of the lifting unit, and metal horizontal location of nominal building surface site.

[0014] In the particular embodiment, the lifting unit is equipped with stabbing boards for the work of personnel and positioning of load.

[0015] The indicated signs are essential, and are interrelated with each other for the creation of a stable complex of essential features, necessary for the achievement of the required technical result.

[0016] No differential peculiarities of the declared system were revealed at the search of known systems with the similar mission, which certifies that this technical decision is in compliance with patentability condition.

[0017] The present invention is explained with certain examples, which, however, are not unique, but clearly demonstrate the achievement possibility with the enumerated cumulative evidence of the required technical result.

[0018] The variants of lift crane system execution are presented in the following figures:

Fig. 1 - external view of the lift crane system during its operation at the transport facility;

Fig. 2 - external view of the lift crane system during its operation at the construction site (separately from the transport facility);

Fig. 3 - external view of the lift crane system during its operation on the construction;

[0019] According to the present invention a lift crane system is considered, which is attached to the external side of a construction 1, and contains at least one lifting unit 2, entering in contact with the at least one rail 3 for moving the lifting unit 2 along the rail 3, attached to the construction structure 1; boom crane 4, which has a rotating 5 and rotary 6 mechanism to support one end of the boom that comprises at least telescopic section 7 (one or several) for reaching any point on the construction or under it; transport facility 8 with the mechanism for forwarding and returning the lifting unit 2, for its holding near the rail 3 for the the fixation or releasing (fig. 1 - 3).

[0020] It is possible to use a lifting unit and an H-shaped rail, known from the indicated system prototype to the introduced patent system EAPO 008405, as a running gear of the lifting unit 2 and the rail, being in the interaction with it 3 to secure moving of the lift crane system along the construction. The lifting unit and the H-shaped rail enter in contact with each other with the help of supporting wheels of the lifting unit, located in the H-shaped rail. Movement of the lift is performed due to the interaction of driver gears of the lifting unit, driven by electric engines of the lift crane system with the rail skids of the H-shaped rail. Although a lifting unit is presented with the engines inside, a cable or hydraulic system may me alternatively used for the transportation of the lifting unit along the rail, attached to the construction. Other means of attachment of the lifting unit to the construction may be used besides the rail with wheels, which stays within the present invention.

[0021] The mechanism for forwarding and returning the lifting unit 2 of transport facility 8 (also known from patent EAPO 008405) contains the rotating mechanism 9, fixed at the transport facility 8, rotary mechanism 10, fixed at the rotating mechanism 9, a telescopic boom 11 and secondary rotating 12 and a rotary mechanism 13, which have a movable supporting area 14. With the help of bifurcated elements 15 of supporting area 14, which interact with the axial slots 16, located in the body of the lifting unit 2, clutch of the lifting unit 2 is possible, as well as performance of various manipulations with it: loading at the transport facility 8, transportation in the transport facility 8, delivery of the lift device to the rail 3 of construction 1, and to nominal locations for the mounting of the lifting unit 2 on the transport facility 8, and building surface (figure 1).

[0022] Also, as it is known from patent EAPO 008405, a dismountable rail section 17 of the rail 3 is attached to the running gear of the lifting unit 2 in the transporting state, which enables to perform loading of the lifting unit to the rail 3 of construction 1. This operation is performed by means of attachment of dismountable rail section 17 in the nominal location 18, placed at the line of the main rail 3 of construction 1. The delivery of the lift device with dismountable rail section 17 to the nominal location 18 is performed with the help of the c described above mechanism for forwarding and returning the lifting unit 2 of transport facility 8. Fixation of dismountable rail section 17 on the nominal location 18 is performed by personnel at the auxiliary site 19 with the help of rail retainers 20 of dismountable rail section 17 (figures 1 and 3). As a result of the described operation the dismountable rail section 17 with the lifting unit 2 is connected on it with the rail 3 of construction, and the lifting unit 2 gets an opportunity to move along the common rail 3 up and down of construction 1 (figure 3).

[0023] Lifting unit 2 is equipped with supporters, securing the attachment of the lifting unit 2 to the construction structure 1 for the increase of the load capacity of the boom crane 4 during the operation thereof on the construction. The indicated elements are made as steel dismountable beams 21, interacting with metal sheaths 22 and 23 of the lifting unit 2 and the construction 1 respectively. Fixation of steel dismountable beams 21 in the metal sheaths 22 and 23 of the lifting unit 2 and the construction 1 is performed by means of screw couplings 24, interacting with the holes, made in steel dismountable beams 21, and in metal sheaths 22 and 23 of the lifting unit 2 and the construction 1 (figure 3).

[0024] Transport facility 8 comprises a nominal location 25 for mounting the lifting unit 2 on the transport facility 8 so that the boom crane 4 can operate directly on the transport facility 8. The indicated nominal location 25 is made in a form of metal horizontal location 26, the surface of which corresponds to the surface of the lower surface of the lifting unit 2. Mounting of the lifting unit 2 on the metal horizontal location 26 of nominal location 25 of transport facility 8 is performed by means of screw elements 27, which interact with the holes, made in the lower surface of the lifting unit 2, and metal horizontal location 26 of nominal site 25 of transport facility 8. Besides, transport facility 8 has a nominal location 28 for the attachment of balance beam 29 (fig. 1).

[0025] The building surface of the construction 1 includes at least one nominal location 30 for mounting of lifting unit 2 on the building surface, so that the boom crane 4 can operate in the vicinity of the construction 1, but separately from the transport facility 8. The indicated nominal location 30 is made in a form of metal horizontal location 31, the surface of which corresponds to the surface of the lower surface of the lifting unit 2. Mounting of the lifting unit 2 on the metal horizontal location 26 of nominal location 25 of the building surface of construction 1 is performed by means of screw elements 27, which interact with the holes, made in the lower surface of the lifting unit 2, and metal horizontal location 26 of nominal site 25 of the building surface of construction 1 (fig. 2).

[0026] The lifting unit 2 is equipped with stabbing boards 33 for the work of personnel and positioning of load (fig. 3).

[0027] The variant of operation of the claimed lift crane system is as follows:

The lift crane system in the folded (for the transportation) position is transported via transport facility 8 to the building surface of construction 1. Transport facility 8 is mounted at the flat level surface in the immediate neighborhood of location of the construction site 1, and the transport facility 8 is being prepared to operation (for example, its support structures are pulled out).

[0028] After that with the help of a mechanism for forwarding and returning the lifting unit 2 of transport facility 8 the lift crane system is moved to nominal location 25 of transport facility 8, which is intended for the mounting of system lifting unit 2. This operation involves the mechanism for forwarding and returning the lifting unit 2: rotating 9 and rotary mechanisms 10 for of transport facility 8, telescopic boom 11, rotary 12 and rotating 13 mechanisms of telescopic boom 11.

[0029] With the help of the enumerated elements, the supporting area 14, fixed flexibly on the telescopic boom 11 with the lifting unit 2, situated at it, mounts the lifting unit 2 with its lower surface on the metal horizontal location 26 of the nominal location 25 of transport facility 8. Further the personnel performs the attachment of lifting unit 2 on the metal horizontal location 26 of nominal location 25 of transport facility 8 by means of screw elements 27, which interact with the holes, made in the lower surface of the lifting unit 2, and metal horizontal location 26 of nominal site 25 of transport facility 8.

[0030] Upon the completion of this operation the bifurcated elements 15 are unblocked, which join the lifting unit 2 with the supporting area 14. Then the bifurcated elements 15 are taken from the axial slots 16 of the lifting unit 2 with the help of corresponding manipulations with the elements of mechanism for forwarding and returning the lifting unit 2; and the whole mechanism for forwarding and returning the lifting unit 2 is fixed in such position that it will not further interfere with the work of the crane system (for example, as shown in fig. 1).

[0031] As a result of these operations the lift crane system is maintained on the body of transport facility 8 in the upright (operating) position. After the all necessary communications are connected with the system, and all tests are passed, the lift crane system is fully operationally ready.

[0032] A successive load of balance beam 29 elements to the nominal location 28 of transport facility 8 is performed with the help of the boom crane to increase the load capacity of the lift crane system during its performance.

[0033] After the completion of this operation the necessary load capacity is secured for the lift crane system, and the system starts the construction of its nominal location 30 at the building surface.11 The completion of the nominal location construction 30 on the building surface is mounting of metal horizontal location 31 on it.

[0034] Upon the construction completion of the nominal location 30 at the building surface the necessity to use transport facility 8 as a support for the lift crane system is eliminated.

[0035] All elements of balance beam are taken away from the transport facility 8 with the help of boom crane 4 of the lift crane system. The bifurcated elements 15 are inserted and blocked in the axial slots 16 of the lifting unit 2 after all necessary manipulations with the elements of the mechanism for forwarding and returning the lifting unit 2 of transport facility 8. All communications are removed from the system, and all screw elements 27 are unscrewed.

[0036] Then, with the help of a mechanism for forwarding and returning the lifting unit 2 of transport facility 8, the lift crane system is moved from the body of transport facility 8 to the nominal location 30 on the building surface. After the lifting unit 2 of the system is mounted on metal horizontal location 31, the personnel fixes the lifting unit 2 with screw elements 32 (fig. 2).

[0037] As a result of these operations the lift crane system is maintained in the nominal location 30 on the building surface in the upright (operating) position. After all necessary communications are connected with the system and all tests are passed, the lift crane system is ready for the erection of the lower part of construction 1.

[0038] Simultaneously with the erection of construction 1, with the help of the lift crane system 1, the rail 3, nominal location 18 for the dismountable rail section 17, auxiliary location 19 of the nominal location 18, as well as metal sheaths 23 are mounted on location 1. Access to any point of the erected construction 1 for the boom crane 4 of the system is secured by means of its rotating 5 and rotary 6 mechanisms, as well as telescopic sections 7. However, while the system is not moved vertically, its possibilities are limited on the hight of operation, and along with the growth of the erected construction, there is a moment, when the system possibilities are limited in such position, and there appears a necessity of moving of the lift crane system to the surface of construction 1.

[0039] In order to perform this operation, transport facility 8 arrives again at the building surface, and with the help of its mechanism for forwarding and returning, the system is moved to the nominal location 18 of construction 1. Then dismountable rail section 17, fixed on the lifting unit 2, is mounted on the nominal location 18, and, with the help of personnel on the auxiliary location 19, the indicated section 17 is fixed with rail retainers 20. All necessary communications are connected to the system, and all tests are passed. Then with the help of the boom crane 4 and personnel, stabbing boards 33 are mounted to the lifting unit 2 for the operation of personnel and load placement.

[0040] Transport facility 8 leaves the building surface, and the lift crane system is moved from the dismountable rail section 17 to the basic rail 3 of construction 1 for the resumption of its work on the construction site. To increase the load capacity of the lift crane, mounting of the support structures, steel dismountable beams 21 is performed in the process of its operation directly at construction 1, at certain elevation points of construction 1, where the system is stopped for work, with the help of the boom crane 4 of the system and personnel at the stabbing boards 33,

[0041] During this mounting, performed with the , boom crane 4, beams 21 are inserted in metal sheaths 22 of the lifting unit 2 by personnel, are moved further into metal sheaths 23 of construction 1, and are fixed in both sheaths 22 and 23 by screw couplings 24. Dismounting of beams 21 is performed in the reverse sequence.

[0042] During the growth of the erected construction (and the rail 3 accordingly) the lift crane system is moved higher and higher, and at each elevation point of construction 1, specified for the placement of the system in the operating position, the indicated operations of mounting/dismounting of beams 21 are repeated. During the movement of the system along the rail 3 of construction 1 the indicated beams can be stored on the upper surface of the erected construction.

[0043] After the completion of the construction erection, the lift crane system may stay on the rail of construction 1 constantly for everyday maintenance of construction, and may be brought and mounted at construction occasionally for the performance of certain operations.

[0044] This invention is used in the industry, as it may be realized with the use of known technologies, used at production of lift and crane devices, including transport machine building.
