AI Technical Summary
During tunnel construction, the extension of live cables leads to the occupation of construction space due to stacking, and the use of existing cable reels can easily cause internal torsional deformation and damage to the cables.
An electric slip ring is installed inside the cable reel, which works in conjunction with a brush installed on the winding post to connect the cable to the slip ring and the winding post to the brush. This avoids internal torsional deformation when the cable is directly wound around the reel, and the electrical connection between the slip ring and the brush prevents damage at the connection point of the two-section cable.
This allows for smooth cable coiling, avoiding internal twisting deformation and damage to connections, while maintaining cable neatness and safety and reducing space occupation at the construction site.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable storage technology in tunnels, and more particularly to a vehicle for storing and retrieving live cables. Background Technology
[0002] In tunnel construction, the length of live cables extends with the construction progress. Initially, there are issues with live cables being piled on the ground, tangling and occupying construction space. Similarly, there are issues with cable storage and deployment. When using existing cable reels, the cable is directly output and then wound around the reel. Over time, this can easily cause internal twisting and deformation of the output cable, leading to cable damage. Utility Model Content
[0003] The technical problem to be solved by this utility model is to address the above-mentioned technical deficiencies by providing a live cable winding and unwinding vehicle. It adopts an electric slip ring set inside the cable reel and an electric brush set on the winding post to achieve the connection between the input cable and the electric slip ring, while the cable wound on the reel is connected to the electric brush on the winding post. Directly winding the cable around the reel can easily cause internal torsional deformation.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: It includes a base plate and a winding post disposed on the base plate; the winding post and the base plate are rotatably disposed in a direction perpendicular to the base plate; an electric slip ring is disposed inside the winding post extending from the base plate; an electric brush is disposed inside the winding post corresponding to the electric slip ring; a cover plate with a centrally upward protruding section is disposed on the top of the winding post; a ring cover is disposed on the cover plate extending to the side wall of the winding post; the side wall of the winding post expands downward and outward from the ring cover.
[0005] To further optimize this technical solution, the slip ring is hollow; the slip ring has a longitudinal channel connecting the inside of the winding post to the outside of the base plate.
[0006] To further optimize this technical solution, the winding post and the base plate are rotatably connected by a pressure bearing located on the outer side of the channel.
[0007] To further optimize this technical solution, a gap is left between the base plate and the bottom of the winding post; supporting rollers are provided around the base plate at positions corresponding to the bottom of the winding post. To further optimize this technical solution, a reserved hole for the cable to pass through is provided at the bottom of the winding post. To further optimize this technical solution, wheels are provided under the base plate. To further optimize this technical solution, power terminals are provided around the upper circumference of the electric slip ring.
[0008] By using an electric slip ring inside the cable reel and a brush on the winding post, the input cable is connected to the electric slip ring, while the cable wound around the reel is connected to the brush on the winding post. Directly winding the cable around the reel can easily cause internal torsional deformation. At the same time, the electrical connection between the electric slip ring and the brush avoids the problem of easy damage at the connection point of the two-section cable.
[0009] Compared with existing technologies, this utility model has the following advantages: It employs an electric slip ring inside the cable reel that works in conjunction with an electric brush on the winding post. This structure effectively ensures the connection between the input cable and the slip ring, while the cable wound on the reel connects to the electric brush on the winding post. Directly winding the cable onto the reel can easily cause internal torsional deformation. The downward and outward expanding shape of the winding post allows for support between the cables and between the cables and the winding post as the number of turns increases, preventing the upper-wound cable from falling downwards. Simultaneously, the cover plate ensures the moisture-proof and waterproof performance inside the winding post, preventing haphazardly pulling and piling up live cables during construction, reducing the limited space at the construction site, and contributing to a safe, clear, and tidy power line environment.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model. Detailed implementation method:
[0015] Referring to Figures 1-2, the live cable winding and unwinding vehicle is characterized by: including a base plate 1 and a winding post 2 disposed on the base plate 1; the winding post 2 is rotatably disposed with respect to the base plate 1 in a direction perpendicular to the base plate 1; an electric slip ring 3 is disposed within the winding post 2 extending from the base plate 1; an electric brush 4 is disposed within the winding post 2 corresponding to the electric slip ring 3; a cover plate 5 with an upwardly protruding center is disposed on the top outer surface of the winding post 2; a ring cover 6 is disposed on the side wall of the winding post 2 extending from the ring cover 6; the side wall of the winding post 2 expands downward and outward from the ring cover 6. The arrangement of the cover plate and the ring cover 6 ensures that water flowing from the upper part will flow down the outer wall of the winding post without accumulating and corroding at the upper part of the winding post or seeping into the interior of the winding post.
[0016] As shown in Figures 1-2, the slip ring 3 is hollow; a longitudinal channel is provided inside the slip ring 3, connecting the inside of the winding post 2 to the outside of the base plate 1. The winding post 2 and the base plate 1 are rotatably connected by a pressure bearing located outside the channel. A power terminal 9 is provided around the upper circumference of the slip ring 3. An external cable extends from bottom to top through the channel into the winding post, further connecting to the power terminal.
[0017] As shown in Figures 1-2, a gap is left between the bottom of the base plate 1 and the bottom of the winding post 2; support rollers 7 are provided around the base plate 1 at positions corresponding to the bottom of the winding post 2. A pre-drilled hole is provided at the bottom of the winding post 2 for the cable to pass through. A wheel 8 is provided under the base plate 1. The brush and slip ring cooperate to ensure that the winding post maintains a constant connection during rotation, while avoiding damage to the wire connection end. The power supply cable is connected from the brush, passes through the pre-drilled hole to the outside of the winding post, and is wound around the winding post for use.
