Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and specifically to an improved cable tray with a fixed structure. Background Technology

[0002] Cable trays are commonly used to install utility and industrial cables. Cable trays generally come with metal supports and composite material supports. The metal supports are typically made by rolling steel or aluminum alloy into the required profiles and then welding or assembling them with fasteners, meeting the cable installation needs under various environmental conditions.

[0003] When using cable trays, multiple cables may be installed in the same cable tray. However, existing cable trays do not have a structure to separately fix different cables. The cables are intertwined in the cable tray, which makes it inconvenient to inspect and maintain individual cables later. Moreover, the intertwined cables also pose safety hazards. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing an improved cable tray with a fixed structure. This solves the problem that existing cable trays do not have a structure for separately fixing different cables, resulting in cables being intertwined within the cable tray. This causes inconvenience during the later inspection and maintenance of individual cables, and the intertwined cables also pose safety hazards.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An improved cable tray with a fixed structure includes a cable tray body, which contains multiple load-bearing components. Each load-bearing component includes a load-bearing plate, with symmetrically arranged guide blocks on both sides of the load-bearing plate. Multiple evenly distributed fastening grooves are formed on the top end face of the load-bearing plate, and an inwardly recessed first clamping groove is formed on the load-bearing plate between two adjacent fastening grooves. A cable tray cover plate is detachably provided on the cable tray body, and a fixing component is provided at the bottom of the cable tray cover plate to fix the cable in a one-to-one correspondence with the load-bearing components.

[0007] The fixing component includes a fixing plate. The bottom end face of the fixing plate is provided with a fastening plate corresponding to the fastening groove. A second clamping groove is provided on the fixing plate between two adjacent fastening plates. An adjusting clamping plate with an arc-shaped structure is provided in the second clamping groove. An adjusting rod that is slidably connected to the fixing plate is provided on the adjusting clamping plate.

[0008] As a preferred technical solution of this utility model, the main body of the cable tray is provided with a first mounting hole for inserting mounting bolts, and the cover plate of the cable tray is provided with a second mounting hole that is connected to the first mounting hole.

[0009] By using the above technical solution and the installation of bolts in conjunction with the first and second mounting holes, the connection strength between the cable tray body and the cable tray cover plate is improved.

[0010] As a preferred technical solution of this utility model, a connecting column with one end fixedly connected to the cable tray cover plate is provided on the top end face of the fixing plate.

[0011] As a preferred embodiment of this utility model, an adjusting spring is sleeved on the outside of the adjusting rod between the adjusting clamping plate and the second clamping groove.

[0012] By using the above technical solution and by utilizing the setting of the adjusting spring, the elastic force generated by the compression of the adjusting spring can be used to further clamp and fix the cable.

[0013] As a preferred technical solution of this utility model, guide grooves for displacement of guide blocks are provided on the two inner side walls of the cable tray body.

[0014] By using the above technical solution and the guide groove and guide block, the stability of the vertical displacement of the bearing plate is improved.

[0015] As a preferred technical solution of this utility model, a drive threaded groove is provided through the main body of the cable tray, and a drive threaded post is provided in the drive threaded groove. One end of the drive threaded post is rotatably connected to the bearing plate, and the other end of the drive threaded post extends to the outside of the main body of the cable tray and is provided with a drive turntable.

[0016] The above technical solution utilizes the setting of the drive threaded column to facilitate the displacement of the load-bearing component by the staff.

[0017] As a preferred technical solution of this utility model, a guide rod with one end fixedly connected to the bearing plate is slidably connected to the bridge frame body on both sides of the drive thread groove.

[0018] By using the above technical solution and the guide rod, the stability of the displacement of the load-bearing component driven by the threaded column is improved.

[0019] As a preferred embodiment of this utility model, anti-slip grooves are provided on both the inner wall of the first clamping groove and the inner wall of the adjusting clamping plate.

[0020] The above technical solution, by using anti-slip grooves, improves the stability of the cable tray fixing and clamping.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This utility model can separate and place cables of different specifications within the cable tray body, and can also clamp and fix cables of different specifications, facilitating subsequent cable maintenance by staff and improving the stability of cables of different specifications laid within the cable tray body. When laying cables within the cable tray body, cables of different specifications are placed in the first clamping groove on the bearing plate, and then the cable tray cover plate is installed on the cable tray body and fixed by inserting mounting bolts into the connected first and second mounting holes, so that the fixing component is located directly above the bearing component. By driving the turntable to rotate and driving the threaded column to move the bearing plate upward, the adjusting clamping plate is brought into contact with the outer wall of the cable in the first clamping groove. At this time, the elastic force generated by the compression of the adjusting spring further clamps and fixes the cable, thereby fixing and clamping the cable in the first clamping groove.

One end of the adjusting spring is fixedly connected to the adjusting clamping plate 405, and the other end of the adjusting spring is fixedly connected to the inner wall of the second clamping groove 404. By setting the adjusting spring, the elastic force generated by the adjusting spring under pressure can be used to further clamp and fix the cable.

[0041] The working principle of this utility model is as follows:

[0042] When laying cables within the cable tray body 1, cables of different specifications are placed in the first clamping groove 303 on the support plate 301. Then, the cable tray cover plate 2 is installed on the cable tray body 1 and fixed by inserting mounting bolts 7 into the connected first mounting hole 103 and second mounting hole, so that the fixing component 4 is directly above the support component 3. The drive turntable 5 rotates, driving the threaded column to move the support plate 301 upwards, causing the adjusting clamping plate 405 to contact the outer wall of the cable in the first clamping groove 303. At this time, the elastic force generated by the adjusting spring further clamps and fixes the cable, thus fixing the cable in the first clamping groove 303. This invention can separate and place cables of different specifications within the cable tray body 1, and can also clamp and fix cables of different specifications, facilitating later cable maintenance and improving the stability of cables of different specifications laid within the cable tray body 1.
