Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to an auxiliary fixing device for cable trays. Background Technology

[0002] Cable trays are structural systems used to support and manage cables. They are widely used in indoor and outdoor, industrial and commercial buildings, providing physical protection and support for cables, ensuring that cables can be arranged in an orderly manner after installation, facilitating maintenance and expansion.

[0003] In the prior art, such as Chinese Patent No. CN222601944U, a cable tray fixing device for a steel structure factory building relates to the field of cable tray fixing technology. It includes a concave cable tray body, with an inverted concave cable tray cover plate snapped onto the top of the body. Connecting protrusions are symmetrically welded to both sides of the cable tray body, and a rectangular connecting plate is installed at the bottom of the body. A buffer plate is then installed at the bottom of the connecting plate, and a limiting plate is fixedly attached to the bottom of the buffer plate. Spring damping shock absorbers are equidistantly installed inside the limiting plate, and a support plate is fixedly attached to the bottom of the spring damping shock absorbers. A fixing frame is installed below the support plate, and main fixing rods and auxiliary fixing rods are symmetrically arranged at both ends of the fixing frame. This invention, through its design, can effectively fix the cable tray and effectively dampen vibrations, thereby reducing the risk of loosening of the fixing device and minimizing safety hazards.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: Although the fixing device can fix the cable tray and dampen it through the shock-absorbing components, the height of the fixing device is fixed and cannot be moved up or down. In building structures, the ceiling height is not uniform, and the cables inside the cable tray can reduce the difficulty of maintenance personnel in the later maintenance and repair after long-term operation. In addition, the fixing device can only fix the cable tray of a single model and cannot fix cable trays of different sizes, which makes it less practical.

[0005] Therefore, how to provide an auxiliary fixing device for cable trays is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide an auxiliary fixing device for cable trays. By providing a driving component, the main body of the cable tray can be moved up and down while simultaneously rotating the transmission component at the bottom. The transmission component can clamp the main body of the cable tray, thereby solving the problems mentioned in the background art.

[0007] A cable tray auxiliary fixing device according to an embodiment of the present invention includes a top plate, a plurality of fixing rods fixedly connected to the top of the top plate, two support frames fixedly connected to the middle of the top of the top plate, a rotating motor fixedly connected between the bottom of the support frames, a rotating shaft fixedly connected to the output end of the rotating motor, a driving gear fixedly connected to the bottom of the rotating shaft, a synchronous belt meshing with the outer wall of the driving gear, driven gears meshing with both sides of the inner wall of the synchronous belt, a reciprocating screw fixedly connected inside the driven gear, a rotating block threadedly connected to the outer wall of the reciprocating screw, a movable outer sleeve fixedly connected to the outer wall of the rotating block, a connecting block fixedly connected to the bottom of the movable outer sleeve, and a support plate fixedly connected to the side of the connecting block adjacent to it.

[0008] As a preferred embodiment of this utility model: the bottom of the reciprocating screw is fixedly connected to a driving bevel gear, and the bottom of the driving bevel gear is meshed with a driven bevel gear.

[0009] As a further preferred embodiment of this utility model: a threaded rod is fixedly connected inside the driven bevel gear, and a movable block is threadedly connected to the outer wall of the threaded rod.

[0010] As a further preferred embodiment of this utility model: a sliding fixing block is fixedly connected to the top of the movable block, a telescopic spring plate is fixedly connected to one side of the sliding fixing block, and sliding blocks are fixedly connected to the front and rear sides of the inner wall of the sliding fixing block.

[0011] As a further preferred embodiment of this utility model: a fixing block is rotatably connected to the outer wall of the reciprocating screw, and the top of the fixing block is fixedly connected to the top plate.

[0012] As a further preferred embodiment of this utility model: a cable tray body is provided on the top of the support plate, and a cable tray cover plate is snapped onto the top of the cable tray body.

[0013] As a further preferred embodiment of this utility model: sliding grooves are provided on the front and rear sides of the support plate, and the sliding grooves are slidably connected to the sliding blocks.

[0014] The beneficial effects of this utility model are:

[0015] When the cable tray body needs to be lowered for maintenance, first start the rotating motor to drive the rotating shaft at the output end. The rotation of the rotating shaft drives the bottom drive gear, which in turn drives the synchronous belt. The rotation of the synchronous belt drives the driven gears on both sides of the inner wall, which in turn drives the internal reciprocating screw. The rotation of the reciprocating screw drives the rotating block on the outer wall downwards, which in turn drives the movable outer sleeve on the outer wall downwards. The movement of the movable outer sleeve drives the cable tray body downwards. As the cable tray body moves downwards, the reciprocating screw also drives the bottom drive bevel gear to rotate, which in turn drives the driven bevel gear to rotate. The rotation of the driven bevel gear drives the movable block to move to the opposite side, which in turn drives the top sliding fixing block to move to the opposite sides. This removes the clamping and fixing of the cable tray body, allowing it to be clamped out when it reaches the ground, facilitating inspection. When moving the cable tray body upwards, clamping and fixing can also be performed during the upward movement. Attached Figure Description

Two support frames 3 are fixedly connected to the middle of the top of the top plate 1. A rotating motor 13 is fixedly connected between the bottoms of the support frames 3. A rotating shaft 16 is fixedly connected to the output end of the rotating motor 13. A drive gear 17 is fixedly connected to the bottom of the rotating shaft 16. A synchronous belt 2 is meshed with the outer wall of the drive gear 17. The synchronous belt 2 will not disengage from the gear due to tension. Driven gears 14 are meshed with both sides of the inner wall of the synchronous belt 2. A reciprocating screw 5 is fixedly connected inside the driven gear 14. A fixing block 6 is rotatably connected to the outer wall of the reciprocating screw 5. The top of the fixing block 6 is fixedly connected to the top plate 1. A rotating block 23 is threadedly connected to the outer wall of the reciprocating screw 5. A movable outer sleeve 7 is fixedly connected to the outer wall of the rotating block 23. A connecting block 12 is fixedly connected to the bottom of the movable outer sleeve 7. A support plate 11 is fixedly connected to the side of the connecting block 12.

[0024] The support frame 3 supports the rotating motor 13. Starting the rotating motor 13 drives the rotating shaft 16 to rotate, which in turn drives the drive gear 17 to rotate. The drive gear 17 then drives the synchronous belt 2 to rotate, which in turn drives the driven gear 14 to rotate. The driven gear 14 then drives the reciprocating screw 5 at the bottom to rotate, which in turn drives the rotating block 23 to move up and down. The rotating block 23 then drives the movable outer sleeve 7 to move up and down, which in turn drives the bridge frame body 10 at the bottom of the movable outer sleeve 7 to move up and down.

[0025] refer to Figure 1 , Figure 4 As shown, a driving bevel gear 19 is fixedly connected to the bottom of the reciprocating screw 5. A driven bevel gear 20 is meshed with the bottom of the driving bevel gear 19. A threaded rod 21 is fixedly connected inside the driven bevel gear 20. A movable block 22 is threadedly connected to the outer wall of the threaded rod 21. A sliding fixed block 15 is fixedly connected to the top of the movable block 22. A telescopic spring plate 18 is fixedly connected to one side of the sliding fixed block 15. Sliding blocks 24 are fixedly connected to the front and rear sides of the inner wall of the sliding fixed block 15. A cable tray body 10 is provided on the top of the support plate 11. A cable tray cover plate 8 is snapped onto the top of the cable tray body 10. Sliding grooves 9 are opened on the front and rear sides of the support plate 11. The sliding grooves 9 are slidably connected to the sliding blocks 24 inside.

[0026] The reciprocating screw 5 rotates, driving the active bevel gear 19 to rotate. The active bevel gear 19 rotates, driving the driven bevel gear 20 to rotate. The driven bevel gear 20 rotates, driving the threaded rod 21 to rotate. The threaded rod 21 rotates, driving the movable block 22 to move to the adjacent or distant side. The movable block 22 moves, driving the sliding fixed block 15 to move. The telescopic spring plate 18 on the adjacent side of the sliding fixed block 15 clamps and fixes the cable tray body 10.

[0027] Working principle:

[0028] When the cable tray body 10 needs to be lowered for maintenance, the rotating motor 13 is first started to drive the rotating shaft 16 at the output end to rotate. The rotation of the rotating shaft 16 drives the bottom drive gear 17 to rotate, which in turn drives the synchronous belt 2 to rotate. The rotation of the synchronous belt 2 drives the driven gears 14 on both sides of the inner wall to rotate, which in turn drives the internal reciprocating screw 5 to rotate. The rotation of the reciprocating screw 5 drives the rotating block 23 on the outer wall to move downward. The movement of the rotating block 23 drives the movable outer sleeve 7 on the outer wall to move downward. The movement of the movable outer sleeve 7 drives the cable tray body 10 to move downward. When the cable tray body 10 moves downward, the reciprocating screw 5 also drives the bottom drive bevel gear 19 to rotate. The rotation of the drive bevel gear 19 drives the driven bevel gear 20 to rotate, which in turn drives the movable block 22 to move to the opposite side, causing the top sliding fixing block 15 to move to the opposite sides, thus releasing the clamping and fixing of the cable tray body 10.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
