[0002] Currently, when laying underground track monitoring cables in coal mines, cable trays can be used for protection. However, existing cable trays connect each section with screws, which takes a lot of time to install and thus affects the efficiency of cable laying.

[0003] Existing technology CN218386614U discloses a cable tray, including a first cable tray with a rectangular groove on its outer surface. A torsion spring is fixedly connected to the outer surface of a fixed post. A limit block is fixedly connected to the bottom of a rotating plate, and a connecting block is fixedly connected to the bottom of a protrusion. A second cable tray is fixedly connected to the right end of the connecting block. This invention, by setting a limit block and a protrusion, utilizes the engagement between the limit block and the protrusion to improve the convenience of the device, facilitating quick installation and disassembly of the first and second cable trays, thus improving the efficiency of device connection. The torsion spring and rotating plate, connecting the fixed post and the rotating plate with the torsion spring, allow the rotating plate to exert force on the torsion spring when pressed. When the rotating plate loses its support, it automatically rebounds under the action of the torsion spring, improving the flexibility of the device.

[0004] However, in actual use, the cables inside the cable trays are difficult to categorize and set up, which can easily cause them to become tangled and make subsequent maintenance inconvenient. Utility Model Content

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1:

[0021] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the cable anti-tangle wiring device. Figure 2 This is a front view of the limiting post 105. This utility model provides a cable anti-tangling wiring device: including a cable tray body 101, a cover plate 102, and an installation assembly.

The locking component includes a T-shaped screw 107 and an anti-loosening nut 108. The supporting component includes a roller 109 and a limiting component. The limiting component includes a first bracket 110 and a second bracket 111. This solution solves the problem that existing cable trays, in actual use, are difficult to classify and arrange internal cables, easily causing them to tangle and making subsequent maintenance inconvenient. It is understood that the aforementioned solution can achieve classified arrangement of monitoring cables, avoiding tangling and making subsequent maintenance more convenient.

[0022] In this embodiment, a detachable cover plate 102 is provided on the top of the cable tray body 101. Threaded holes are provided at corresponding positions on the top end face of the cable tray body 101 to facilitate connection of the cover plate 102 by bolts. The cable tray body 101 is mounted on an external support bracket. When connecting two cable tray bodies 101, the connecting part is preferably located on the support bracket, and each support bracket supports the ends of the two cable tray bodies 101. Then, rectangular connecting plates can be symmetrically arranged on the sides of the two cable tray bodies 101, and then the rectangular connecting plates are fixed by self-tapping screws to achieve connection. The self-tapping screws will not interfere with the sliding of the movable plate 103 during installation.

[0023] Several movable plates 103 are detachably connected to the cable tray body 101 and can slide in guide grooves on both sides of the inner wall of the cable tray body 101. Fixed plates 104 are detachably connected to the movable plates 103 and are symmetrically arranged on the movable plates 103. Limiting posts 105 are integrally formed with the fixed plates 104 and are located on the top of the fixed plates 104. A U-shaped through groove is provided on the top of the limiting posts 105. Limiting caps 106 are screwed onto the external threaded end of the top of the limiting posts 105. Locking components are provided on both sides of the movable plates 103, and supporting components are provided at the bottom of the movable plates 103. The movable plate 103 can slide directly within the rectangular groove provided on the inner wall of the cable tray body 101, and the number of movable plates 103 can be set according to actual conditions. The limiting post 105 is integrally formed with the fixed plate 104, and has an external threaded end at the top and a U-shaped groove at the end. The fixed plate 104 is connected to the movable plate 103 by bolts. The movable plate 103 has multiple sets of mating threaded holes to facilitate the position adjustment of the fixed plate 104. The limiting cap 106 can be directly installed on the external threaded end at the top of the limiting post 105. The locking member is used to improve the stability of the movable plate 103 after adjustment, and the supporting member is used to support the movable plate 103 during operation and adjustment, thereby improving stability.

[0024] Secondly, the T-shaped screw 107 is threadedly connected to the movable plate 103 and passes through the movable plate 103, and its bottom disc can abut against the cable tray body 101; the anti-loosening nut 108 is threadedly connected to the T-shaped screw 107 and abuts against the movable plate 103. The T-shaped screw 107 directly engages with the through threaded hole on the movable plate 103, and the anti-loosening nut 108 is directly mounted on the T-shaped screw 107. When loosening or tightening the anti-loosening nut 108, first, an Allen wrench engages with the hexagonal hole at the top of the T-shaped screw 107, then a straight-end wrench is inserted into the anti-loosening nut 108, and then the two wrenches are rotated in opposite directions to loosen or tighten it.

[0025] Then, the roller 109 is disposed at the bottom of the movable plate 103 and can roll inside the bottom of the cable tray body 101; the limiting component is disposed on both sides of the roller 109 and is rotatably connected to the roller 109. The roller 109 is rotatably mounted on the bottom of the movable plate 103 through the limiting component.

[0026] Finally, the first bracket 110 is rotatably connected to the roller 109 and fixed to the bottom of the movable plate 103; the second bracket 111 is rotatably connected to the roller 109 and fixed to the bottom of the movable plate 103, and is located on the side of the roller 109 away from the first bracket 110. The first bracket 110 and the second bracket 111 have the same size, both being L-shaped. The mounting shafts on both sides of the roller 109 are respectively mounted on the first bracket 110 and the second bracket 111 through rotating bearings. The first bracket 110 and the second bracket 111 are respectively fixed to the bottom of the movable plate 103 by bolts.

[0027] To address the problem of existing cable trays where cables are difficult to categorize and easily entangled during actual use, leading to inconvenient maintenance, this invention addresses the issue by first providing a removable cover plate 102 for protection on the cable tray body 101. This cover plate can be directly mounted on external supports for secure installation. When installing monitoring cables, the cover plate 102 is removed, and the limiting caps 106 on the top of the corresponding limiting posts 105 are unscrewed. Then, the cables are placed into the U-shaped slots on the top of the limiting posts 105. Finally, the limiting caps 106 are installed to prevent the cables from detaching from the limiting posts 105. This design ensures efficient monitoring cable installation. The categorized arrangement of cables avoids tangling and facilitates later maintenance. When the position of the movable plate 103 needs to be adjusted, loosen the anti-loosening nut 108, and then rotate the T-shaped screw 107 so that its bottom disc does not abut against the cable tray body 101. Then, the movable plate 103 can be directly pushed to slide to the desired position. During sliding, the roller 109 provides support. When adjusted to the appropriate position, rotate the T-shaped screw 107 so that its bottom disc abuts against the cable tray body 101, and then tighten the anti-loosening nut 108. This solves the problem that existing cable trays are difficult to categorize and arrange internal cables during actual use, which easily leads to tangling and inconvenience in subsequent maintenance.

[0028] Example 2:

[0029] like Figure 3 As shown, where Figure 3This is a schematic diagram of the overall structure of the cable anti-tangle wiring device. Based on the first embodiment, this utility model provides a cable anti-tangle wiring device, which also includes a moisture-proof component, which includes a rectangular plate 201 and a placement box 202.

[0030] The rectangular plate 201 is fixed to the inner wall of the cable tray body 101; the placement box 202 is fixed to the rectangular plate 201 and contains a desiccant. The rectangular plate 201 is fixed to the cable tray body 101 with bolts, and the placement box 202 is connected to the rectangular plate 201 with countersunk bolts.

[0031] In this embodiment, by setting the rectangular plate 201 and the placement box 202, and placing a desiccant in the placement box 202, the humidity of the internal environment of the cable tray body 101 can be reduced, which is beneficial for the cable to be in a dry environment when working. The number of rectangular plates 201 and placement boxes 202 can be set according to the usage.

[0032] Finally, a coal mine underground track monitoring cable can be protected from tangling during wiring by means of the cable anti-tangling wiring device.
