[0023] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0024] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0026] like Figure 1As shown, the utility model includes a mounting plate 1, the inner side of which is provided with four bolt holes 2 in a rectangular array, and an operator can use the bolt holes 2 to fix the mounting plate 1. A lifting frame 3 is installed on one side of the mounting plate 1, and a lifting structure 4 is installed on the inner side of the lifting frame 3. When performing installation work, the operator can use the lifting structure 4 to adjust the height of the cable tray body 12, and the operator can lower the cable tray body 12 to facilitate the maintenance of the cable tray.

[0027] like Figure 2 and Figure 3 When performing lifting work, the operator can use the lifting motor 401 installed above the lifting frame 3. The lifting motor 401 drives the rotating shaft 402 installed at its power end to rotate. A rotating shaft bracket 408 is installed at one end of the rotating shaft 402. The rotating shaft bracket 408 fixes the rotating shaft 402 above the lifting frame 3. The rotating rotating shaft 402 can drive the bevel gear 1 403 installed on its outer side to rotate. The rotating bevel gear 1 403 can drive the meshing bevel gear 2 404 on its outer side to rotate. The rotating bevel gear 2 404 can drive the The lifting screw rod 405 rotates, and the rotating lifting screw rod 405 drives the lifting bracket 406 connected to its outer side thread to move downward. A limit slide bar 407 is installed on the inner side of the lifting bracket 406. The limit slide bar 407 limits the movement of the lifting bracket 406 to ensure that the lifting bracket 406 can be lifted and lowered normally. The lifting bracket 406 can drive the bridge support plate 5 installed on one side to lift and lower. The lifting bracket 406 is equipped with a reinforced tripod 6 between the bridge support plate 5 to provide additional fixation for the bridge support plate 5 and move the cable bridge body 12 installed above.

[0028] like Figure 4 and Figure 5As shown, when the cable tray body 12 is subjected to external impact, the buffer structure 7 installed below the cable tray body 12 can buffer the external impact. When the buffer structure 7 performs the buffering operation, the cable tray body 12 moves downward due to the impact, and the cable tray body 12 pushes the buffer bracket 706 installed below it to move downward. The buffer bracket 706 pushes the buffer connecting rod 705 installed on its inner side to rotate downward. Since the length of the buffer connecting rod 705 is fixed, the buffer connecting rod 705 rotating downward can push the buffer sliding block 703 installed at the other end thereof to move in the direction away from the center of the buffer sliding rod 702. The moving buffer sliding block 703 squeezes the buffer spring 704 installed at the rear, and is squeezed to produce The deformed buffer spring 704 buffers the impact force transmitted from above, and a buffer slide bar 702 is installed on the inner side of the buffer slider 703. Structural brackets 701 are installed on both ends of the buffer slide bar 702. The structural bracket 701 fixes the inner buffer component above the bridge support plate 5. The cable bridge body 12 moving downward pushes the buffer pillar 10 installed below to move downward. The buffer pillar 10 squeezes the pillar spring 11 installed below it, and the squeezed pillar spring 11 provides buffering for the impact force from above. The outer side of the buffer pillar 10 is slidably connected to the limiting slide groove 9 opened on the inner side of the fixed limiting rod 8. The limiting slide groove 9 limits the movement of the buffer pillar 10 to ensure that the buffer pillar 10 can move in a straight line.

[0029] When the utility model is implemented, Figures 1 to 5 As shown, when performing installation work, the operator can use the lifting structure 4 to adjust the height of the cable tray support plate 5 to achieve the purpose of adjusting the height of the cable tray body 12, and when performing cable tray maintenance work, the operator can use the lifting structure 4 to lower the cable tray body 12 to facilitate the operator to perform maintenance work. When the cable tray body 12 is subjected to external impact, the buffer structure 7 installed under the cable tray body 12 can buffer the external impact and prevent the cable tray body 12 from being damaged.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
