    Description

    TECHNICAL FIELD



    [0001] The present invention relates to the field of a device for mounting and dismounting a part, and more particularly to a flange cover mounting and dismounting device.

    BACKGROUND



    [0002] Currently, for most large scale equipment, especially large scale cooling equipment, the process of mounting and dismounting a flange cover is rather complicated. Generally, the position and weight of the flange cover in such equipment decide that the flange cover cannot be mounted and dismounted manually. Instead, it shall be mounted and dismounted by using a tool such as a hanging pillar. Unfortunately, some fragile parts may be disposed surrounding the flange cover, or the flange cover may be interfered with some other parts. Thus, during the overall process of hanging, mounting, and dismounting, it shall pay a special attention to a running route of the hanging pillar. For example, in some large scale horizontal-type coolers, when a flange cover is mounted and dismounted, a conventional vertical-lifting hanging pillar is used to lift the flange cover upwards, it may crash some other parts, and result in damages of the parts, which may even cause security accidents, if serious. In contrast, if a conventional horizontal-rotating hanging pillar is used to lift the flange cover, on one hand, it is difficult to figure out an exact fixing position, and on the other hand, it needs to be adjusted in many factors such as height, length, and so on, to cater to coolers with different sizes, which is extremely complicated and not convenient for operation.

    [0003] US 2005/242051 A1 shows a removable cover support system and method for supporting a cover of a cover assembly having a cover support extension and a cover flange having cover flange holes having a cover flange securing base assembly having a base member and a securing mechanism slidably insertable through at least one of a cover flange hole of a cover assembly having a cover support extension and a cover flange, a retaining sleeve connected to the securing base assembly, a swingarm assembly rotatably supported by the retaining sleeve, and a lifting mechanism connected to the swingarm assembly. The securing mechanism is operably connected to the base member and the lifting mechanism is operably connected to the cover. US 2005/242051 A1 discloses the preamble of the independent claim 1.

    [0004] US 5 617 963 shows an apparatus for mounting an appliance at an opening in a wall, particularly for use with openings in the exterior walls of storage tanks and the like. The apparatus allows men and materials to be safely raised and lowered within the opening, can be moved away from the opening without completely removing the apparatus from the tank, and can be used to mount a variety or different appliances for use through the opening. The apparatus comprises grasping clamps for securing the apparatus to the opening of the wall, an appliance mounting member for connecting an appliance to the grasping clamps, and an appliance for maneuvering through the opening and performing a predetermined task within the tank.

    [0005] WO 2011/010119 A1 shows a closure suitable for use on pipelines and pressure vessels. The closure comprises a door which fits into an aperture of a hub in a member to be closed. A number of arcuate locking members or segment blocks disposed around the periphery of the door for locking the door to the hub. The door is attached to a pivotable arm in order to move the door.

    DETAILED DESCRIPTION



    [0020] FIG. 1 shows a base part 100 of the present invention, which comprises a fastener element 110 and an adjusting element 120. The fastener element 110 is made of a bent board material. For example, the fastener element 110 comprises: a first mounting plate 111; and an upper plate 112 and a lower plate 113 respectively extending from two opposite ends on the first mounting plate 111 towards the same side and bending towards the same side. Optionally, the upper plate 112 and the lower plate 113 respectively form an angle of 90 degrees with the first mounting plate 111, thereby forming a more stable structure. In addition, the first mounting plate 111 is disposed with a fastener hole array 111a. The fastener hole array 111a shall have a corresponding distribution manner with respect to a flange cover mounting surface to be mounted and dismounted, so that the fastener element 110 can be fixed to a device to be mounted and dismounted. Optionally, fastener holes on the fastener hole array 111a can present a plurality of combinations, to cater to the circumstances that different devices to be mounted and dismounted have fastener holes scattered with different spaces or different distributions, thereby greatly enhancing an application scope of the device of the present invention. In addition, the upper plate 112 and the lower plate 113 are respectively disposed with round openings, for mounting a sleeve 114 with a corresponding size. The sleeve 114 has a first opening 114a at a position connecting with the upper plate 112, for accommodating the jib arm assembly that can be matched correspondingly. Optionally, the jib arm assembly 114b is further disposed with an oil hole 114b, so that the jib arm assembly can be pivotally rotated stably under effects of a lubricating oil.

    [0021] The adjusting element 120 comprises a fixing mechanism 121 and a clamping mechanism 122. The fixing mechanism 121 is an L-shaped bracket having a first edge 121a and a second edge 121b. The first edge 121a is disposed with a bolt hole, and is fixed on the fastener element 110 by using a bolt. Optionally, the first edge 121a is fixed on the upper plate 112, and does not shield the first opening 114a of the sleeve 114. The second edge 121b is placed in parallel with the first mounting plate 111, and is disposed with a sliding chute 121c thereon. The clamping mechanism 122 comprises a first clamping element 122a and a second clamping element 122b. The first clamping element 122a is also an L-shaped element, and is disposed with a bolt hole on one edge thereof, and this edge is disposed in parallel with the second edge 121b of the fixing mechanism 121, whereas the other edge thereof is perpendicular to the second edge 121b of the fixing mechanism 121, and is further disposed with a groove for the second edge 121b of the fixing mechanism 121 to move up and down. The second clamping element 122b is similarly disposed with a bolt hole. A first fastening bolt 122c can sequentially pass through the second clamping element 122b, the sliding chute 121c on the second edge 121b of the fixing mechanism 121, and the first clamping element 122a, and fasten them together. Before the fastening operation, the first clamping element 122a and the second clamping element 122b can be moved up and down with respect to the second edge 121b of the fixing mechanism 121, thereby catering to flange cover mounting surfaces with different sizes.

    [0022] In the base part 110, the fastener element 110 is used to be fixed to a mounting surface of a flange cover to be mounted and dismounted by the fastener hole array 111a. The adjusting element 120 is used to clamp the flange cover mounting surface to further enhance the fastening effects. Meanwhile, the adjusting element 120 can be adjusted up and down and front and back respectively, to cater to flange cover mounting surfaces with different sizes and different thicknesses. In this way, the mounting and dismounting device of the present invention can be more widely applied. Thus, it does not need to design different mounting and dismounting devices for equipment with different sizes and different models respectively, thereby greatly reducing the cost.

    [0023] FIG. 2 shows a jib arm assembly 200 matching with the base part 100 according to the present invention. The jib arm assembly 200 comprises a support pillar 210, a swing arm 220, and a lifting lever 230. The support pillar 210 can be pivotally connected to the fastener element 110 of the base part 100. At a position where the support pillar 210 is matched with the upper plate 112 of the fastener element 110, a cover plate 210b is placed surrounding the support pillar 210, and the cover plate 210b is fixed on the upper plate 112. One end of the support pillar 210 is inserted into the first opening 114a of the fastener element 110, and the other end of the support pillar 210 is disposed with the swing arm 220. The swing arm 220 is disposed with a second opening 220a along a length direction, so as to allow the lifting lever 230 to move back and forth therein. Furthermore, the second opening 220a is disposed with two clamping boards 220b therein, to fix the lifting lever 230 at a proper lifting position. The lifting lever 230 is formed by a hanging ring 230a, a lever 230b, and a second fastening bolt 230c. The hanging ring 230a can be used for connecting a cable, and further connecting to a flange cover to be mounted and dismounted. The second fastening bolt 230c is used for fastening the whole lifting lever 230.

    [0024] Optionally, in order to maintain the jib arm assembly 200 within a certain pivotally rotating angle, to avoid crashing between parts, a limiting mechanism may be further disposed to meet the above requirements. For example, a limiting bump 210c is disposed on the cover plate 210b, and a limiting board 210a is disposed on the support pillar 210. By means of the matching effects between the limiting bump 210c and the limiting board 210a, the pivotally rotating motion of the jib arm assembly 200 is restricted.

    [0025] It shall be noted that, many mature jib arm assemblies are provided in the prior art, and as long as the jib arm assembly can be matched with the base part 100 of the present invention, it can similarly constitute the flange cover mounting and dismounting device of the present invention.

    [0026] FIG. 3 and FIG. 4 respectively show a flange cover mounting and dismounting device according to an embodiment of the present invention and their application on a cooling device 300. The flange cover mounting and dismounting device only comprises a base part 100 (comprising a fastener element 110 and an adjusting element 120) and a jib arm assembly 200, so that it is very convenient for assembling, dismounting, and carrying, thereby avoiding a security problem during the above processes. When the flange cover mounting and dismounting device is carried to the cooling device 300 to be mounted and dismounted (for example, in this embodiment, a flange cover 320 in the cooling device needs to be dismounted), the fastener hole array 110a of the fastener element 110 is aligned and fastened with a fastener hole array 311 at a corresponding position on the flange cover mounting surface 310, thereby fixing the fastener element 110. The fastener holes on the fastener hole array 110a present a plurality of combinations. By means of a different fastener hole on the fastener hole array 110a, a fixing position between the fastener element 110 and the flange cover mounting surface 310 can be altered back and forth and left and right, thereby enhancing its application scope. Subsequently, the fixing mechanism 121 in the adjusting element 120 is fixed to the upper plate 112 of the fastener element 110, and the clamping mechanism 122 is adjusted up and down to cater to the changing of a distance between the fastener hole array 311 on the flange cover mounting surface and edges of the flange cover mounting surface. After the adjusting process is completed, the first fastening bolt 122c is screwed tightly, thereby sequentially fastening the second clamping element 122b, the flange cover mounting surface, the fixing mechanism 121, and the first clamping element 122a. In this way, it can further enhance the fixing effects between the whole base part 100 and the flange cover mounting surface. Then, the jib arm assembly 200 is mounted on the base part 100, thereby completing the assembling of the whole device.

    [0027] After the device for dismounting the flange cover is assembled and fixed, the flange cover in the cooling device is connected to the hanging ring 230a of the lifting lever 230 by means of a cable, and the lifting lever 230 is moved along a length direction of the swing arm 220, so as to be adjusted to a most proper lifting position. Then, the fastening bolts at the edges of the flange cover are all dismounted, and then, the swing arm 220 is rotated to open and lift the flange cover, thereby dismounting the flange cover. Considering the mounting process of the flange cover, similar steps can be used. Such mounting and dismounting operations can effectively avoid the problem that several parts may be crashed with the flange cover when the flange cover is lifted vertically.

    [0028] In addition, the flange cover mounting and dismounting device of the present invention can also be applied to mount and/or dismount the flange cover of other devices to be mounted and/or dismounted. When such device is laid down horizontally, or when the flange cover of such device to be mounted and dismounted needs to be mounted or dismounted with respect to the device to be mounted and dismounted along a horizontal direction, the flange cover mounting and dismounting device of the present invention has greater advantages. For example, the flange cover mounting and dismounting device has a more proper fixing surface; and drives the jib arm assembly to pivotally rotate along a horizontal direction, thereby avoiding crashing various other parts and elements distributed in the perpendicular direction, and enhancing the security level.

    [0029] Still referring to FIG. 4, the present invention further provides a cooling device 300, which comprises a flange cover 320 and a flange cover mounting surface 310. Fastener hole arrays 311 are further disposed at a position close to edges of the flange cover mounting surface 310. Optionally, when the flange cover mounting surface is rectangular, the fastener hole arrays 311 are disposed at positions close to four angles of the flange cover mounting surface 310. The fastener hole arrays herein can be used for connecting and fixing a plurality of modules with the same type in the cooling device; and meanwhile can be matched with the fastener hole array 111a in the flange cover mounting and dismounting device as mentioned in the above embodiments. Optionally, the fastener hole array is three holes placed alternatively, which may form a plurality of combinations with the fastener hole array 111a in the flange cover mounting and dismounting device, thereby convenient for moving the device for dismounting the flange cover.

    [0030] It should be noted that, the terms of "up", "down", "front", and "back" and so on mentioned in the present invention are merely used to describe the conventional placing modes when the mounting and dismounting device in this embodiment is used for mounting and dismounting, which, however, are not definitely used, as long as it can fulfill each functions as described in the present invention and have the structure as mentioned in the above detailed description.

    [0031] The detailed description in the present invention have been described above in great detail with reference to the accompanying drawings. Persons skilled in the art can make similar modifications or variations on the detailed features in the embodiments, which undoubtedly fall within the protection scope of the claims.
