Description

Technical fields:

[0001] This utility model relates to the field of cable tray bracket technology, and in particular to a wide cable tray bracket structure that allows for easy addition and removal of cables. Background technology:

[0002] Currently, common fixing methods for single-layer cable trays include single-cantilever sidewall brackets, double-cantilever column brackets, and double-hanger brackets. The single-cantilever sidewall bracket method facilitates adding cables to the tray, but it requires the cable tray to be installed along the sidewall. However, when the cable tray is wide, the size and strength requirements of the cantilever increase significantly, and it occupies a large amount of installation space under and on the sidewall of the cable tray. The double-cantilever column bracket does not rely on the sidewall and also has the advantage of facilitating the addition and removal of cables, but the overall structure is complex. Similarly, when using wide cable trays, the size and strength of the brackets need to increase significantly, and the cable trays on the two cantilever arms must maintain a basic balance in load-bearing capacity; otherwise, uneven stress can lead to deformation and tilting. The double-hanger bracket method has a simple structure and low cost, does not rely on the sidewall, occupies little space under the cable tray, and can adapt to the installation of wide cable trays. However, the conventional double-hanger bracket method presents the problem of difficulty in adding or removing cables after the cable tray is installed. Utility Model Content:

[0003] The purpose of this utility model is to provide a wide cable tray bracket structure that is simple in structure and allows for convenient addition and removal of cables, enabling rapid construction of cable addition and removal.

[0004] This utility model is implemented by the following technical solution: The purpose of this patent is to provide a wide cable tray bracket structure that allows for convenient addition and removal of cables, which includes a bracket beam, a threaded hanger rod one, a hanger rod connecting plate, a hanger lug assembly, and a threaded hanger rod two; a threaded hanger rod one is screwed to one end of the bracket beam, and a through hole is opened at the other end of the bracket beam, the hanger rod connecting plate movably passes through the through hole, and a fixing plate is fixed at the bottom end of the hanger rod connecting plate and movably snapped onto the lower surface of the bracket beam; a snap-fit ​​hole is opened on the hanger rod connecting plate, the connecting rod of the hanger lug assembly is movably snapped into the snap-fit ​​hole, and the threaded hanger rod two is screwed into the threaded sleeve one of the hanger lug assembly.

[0005] Furthermore, the size of the fixing plate is larger than the size of the through hole.

[0007] Furthermore, the snap-fit ​​holes include small holes and large holes arranged sequentially from top to bottom and interconnected with each other. The outer diameter of the baffle is larger than the diameter of the small hole and smaller than the diameter of the large hole. The outer diameter of the connecting rod is smaller than the diameter of the small hole.

[0008] Furthermore, it also includes a "C"-shaped clamp, with an insert plate fixed to the upper end of the clamp and a threaded sleeve fixed to the lower end of the clamp, in which an adjusting screw is screwed; an insertion hole matching the insert plate is provided on the support plate, and the insert plate is movably inserted into the insertion hole; a limit plate is fixed below the bracket beam, and a limit hole corresponding to the adjusting screw is provided on the limit plate, with the tip of the adjusting screw passing through the limit hole and movably abutting against the lower surface of the bracket beam.

[0018] Example: Figure 1-4 As shown, a wide cable tray bracket structure that allows for convenient addition and removal of cables includes a bracket beam 1, a threaded hanger 2, a hanger connecting plate 3, a hanger lug assembly 4, a threaded hanger 5, and a "C"-shaped clamp 6. A threaded hanger 2 is screwed to one end of the bracket beam 1, and a through hole 101 is provided at the other end of the bracket beam 1. The hanger connecting plate 3 movably passes through the through hole 101. A fixing plate 7 is fixed at the bottom end of the hanger connecting plate 3 and is movably engaged with the lower surface of the bracket beam 1. The size of the fixing plate 7 is larger than the size of the through hole 101. A snap-fit ​​hole 31 is provided on the hanger connecting plate 3, and the connecting rod 41 of the hanger lug assembly 4 is movably engaged in the snap-fit ​​hole 31. A threaded hanger 5 is screwed into the threaded sleeve 42 of the hanger lug assembly 4.

[0019] The lifting lug assembly 4 includes a connecting rod 41, a threaded sleeve 42, a baffle 43, and a support plate 44; the threaded sleeve 42 and the baffle 43 are fixedly installed on both sides of the connecting rod 41, and the support plate 44 is fixed on the side of the threaded sleeve 42 away from the connecting rod 41.

[0020] The snap-fit ​​hole 31 includes a small hole 311 and a large hole 312 arranged sequentially from top to bottom and connected to each other. The outer diameter of the baffle 43 is larger than the diameter of the small hole 311 and smaller than the diameter of the large hole 312. The outer diameter of the connecting rod 41 is smaller than the diameter of the small hole 311.

[0021] A plate 8 is fixed at the upper end of the clamp 6, and a threaded sleeve 9 is fixed at the lower end of the clamp 6. An adjusting screw 10 is screwed into the threaded sleeve 9. A socket 441 matching the plate 8 is provided on the support plate 44, and the plate 8 is movably inserted into the socket 441. A limiting plate 11 is fixed below the bracket beam 1. A limiting hole 111 corresponding to the adjusting screw 10 is provided on the limiting plate 11. The tip of the adjusting screw 10 passes through the limiting hole 111 and movably abuts against the lower surface of the bracket beam 1. A handle 12 is fixed at the bottom end of the adjusting screw 10.

[0022] Working principle:

[0023] like Figure 5 As shown, the following methods are needed for cable tray 13 during use to increase the number of cables laid inside the tray:

[0024] First, the cable is temporarily fixed and suspended to the outside of the hanger connecting plate 3 using temporary tools such as wire and tape. Each bracket of the cable tray 13 in the section to be laid needs to be temporarily fixed and suspended in this way. Next, the insert plate 8 at the upper end of the clamp 6 is inserted into the insertion hole 441 on the support plate 44 of the lifting lug assembly 4 to fix the upper end of the clamp 6. Then, the operator manually rotates the adjusting screw 10 at the lower end of the clamp 6 by holding the handle 12, so that its tip passes through the limiting hole 111 on the limiting plate 11 below the bracket beam 1. Then, it continues to rotate, abutting against the lower surface of the bracket beam 1 and lifting the bracket beam 1 upward, so that the hanger connecting plate 3 can move up and down. Then, the hanger connecting plate 3 is moved upward and moved to the side closer to the bracket beam 1, so that the connecting rod 41 is separated from the hanger connecting plate 3. After separation, the hanger connecting plate 3 is pulled out downward. At this time, the cable to be added is placed between the clamp 6 and the bracket beam 1, and then the cable is put into the cable tray 13. After the additional cable is laid, the hanger connecting plate 3 is reinserted into the through hole 101 on the bracket beam 1 and moved towards the side of the lifting lug assembly 4, so that the baffle 43 and the connecting rod 41 pass through the large hole 312. Then, the hanger connecting plate 3 is released, and it moves downward under its own weight, causing the connecting rod 41 to engage in the small hole 311. Afterward, the operator manually rotates the handle 12 to loosen the adjusting screw 10 at the lower end of the clamp 6, removes the clamp 6, and restores the bracket beam 1 to its original installation state, completing the cable placement for one bracket point. The above steps are repeated for cable placement on other brackets. Multiple clamps 6 can be configured to work simultaneously to improve cable laying efficiency.

[0025] The method for removing cables from the cable tray is as follows: When one or more cables are needed in the cable tray 13 during use, the operation steps are basically the same as during installation. First, install the clamp 6, remove the hanger connecting plate 3, remove the cable from the cable tray, and reinstall the hanger connecting plate 3. At this time, the cable to be removed is located between the hanger connecting plate 3 and the clamp 6. Then, remove the clamp 6 and finally retrieve the removed cable.

[0026] This utility model has a simple structure and is easy to implement. Through the cooperation of the connecting plate 3 and the clamp 6, it eliminates the problem of difficulty in adding or removing cables in traditional double-hanger bracket cable trays, and realizes rapid construction for adding or removing cables. It is suitable for application scenarios such as coal mine shafts and tunnels where cables need to be frequently laid and removed. Compared with the current use of cable hooks to lay cables, using cable trays 13 to lay cables has the advantages of neat on-site cable laying, good cable protection performance, and high degree of standardization.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
