Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, specifically relating to a system for laying thick cables in underground coal mines. Background Technology

[0002] High-voltage cables in coal mines are mainly used for power transmission in coal mines to provide power support for various underground equipment. Except for cables connected to handheld or mobile equipment, cables must be suspended when laid underground.

[0003] The cables used in coal mine working faces have diameters ranging from 50 to 185 mm, with single strand lengths reaching up to 1000 meters and maximum weights of up to 10 tons. Conventional cable laying methods involve a large amount of manual labor for hauling, supplemented by cable supports to hang the cables on cable hooks. This is time-consuming, labor-intensive, and requires a large workforce, resulting in extremely high labor intensity and a long construction period. Furthermore, the complex conditions in underground roadways make manual hauling and lifting of cables highly susceptible to accidents. Utility Model Content

[0004] The purpose of this invention is to provide a system for laying out thick cables in underground coal mines, so as to solve the problems of time-consuming, labor-intensive and unsafe cable laying processes.

[0005] This utility model adopts the following technical solution: a system for laying out thick cables in underground coal mines, comprising:

[0006] Multiple cable hooks are arranged in a straight line with intervals; they are fixed to the top of the tunnel along the tunnel's direction.

[0007] Multiple fixed pulleys are arranged in a straight line with intervals; they are fixed to the top of the tunnel using anchor bolts along the tunnel direction and are set near the corresponding cable hooks;

[0008] The power equipment is located at the end of the thick cable route;

[0009] The traction rope has one end located at the starting point of the thick cable and connected to the power equipment, and the other end passes through each fixed pulley in sequence and extends continuously to the starting point of the thick cable.

[0010] The cable reel is hoisted to the top of the tunnel using hoisting anchor cables, at the starting point where a thick cable needs to be laid. The thick cable is wound around the cable reel, and the head end of the thick cable is connected to the traction rope at the starting point of the thick cable layout. Then, the traction rope, driven by the power equipment, pulls the thick cable through each fixed pulley in sequence until the head end of the thick cable reaches the end point of the layout.

[0011] Furthermore, the power equipment is an explosion-proof rubber-wheeled vehicle.

[0012] Furthermore, it also includes: a cable head net sleeve, used to connect the traction rope at the starting point of the thick cable arrangement to the cable head end of the cable reel.

[0013] Furthermore, it also includes a turning guide device installed between two adjacent fixed pulleys at the bend of the tunnel, which is used to guide the traction rope and thick cable at the bend.

[0014] Furthermore, the turning guide device includes:

[0015] The tunnel fixing frame is installed on one side of the inner tunnel sidewall at the bend.

[0016] Three rollers are installed in a triangular shape on the tunnel frame. The three rollers cooperate to form a triangular guide channel, which allows the thick cable to pass through the guide channel and guides the thick cable.

[0017] Furthermore, the tunnel fixing frame includes:

[0018] The side wall fixing rod is set vertically and fixed to the inner side wall of the tunnel at the bend.

[0019] The first ear plate is fixed to the middle of the side wall fixing rod;

[0020] The upper fixing rod is set horizontally, with its inner end fixed to the upper end of the side wall fixing rod and its outer end extending towards the center of the tunnel.

[0021] The lower fixing rod is horizontally set, with its inner end fixed to the lower end of the side wall fixing rod and its outer end extending towards the center of the roadway.

[0022] The second ear plate is fixed to the outer end of the upper fixing rod;

[0023] The third ear plate is fixed to the outer end of the lower fixing rod and is located below the second ear plate;

[0024] A roller is installed between the first ear plate and the third ear plate, between the third ear plate and the second ear plate, and between the second ear plate and the first ear plate, so that the three rollers form a triangular guide channel.

[0025] The beneficial effects of this utility model are:

[0026] This utility model fixes the cable reel to the top of the tunnel and connects the cable to the traction rope. At the same time, it sets a fixed pulley and a turning guide device at the top of the tunnel, which can use power equipment to pull the cable to lay the line by traction rope, saving time and effort and improving production efficiency.

[0027] This invention utilizes a power device to pull the cable via a traction rope during the cable laying process, eliminating the need for manual cable lifting and greatly improving safety.

[0028] This invention allows the cable to be gradually removed from the fixed pulley and then hung on the cable hook after the cable laying is completed. The fixed pulley can be removed and reused, reducing construction costs.

[0029] In the process of laying out the cable, this utility model fixes a turning guide device on the side wall of the tunnel at the bend. The turning guide device uses three rollers to form a triangular guide channel, which can play a good guiding and load-bearing role for the traction rope or cable, and prevent it from deviating or sagging due to gravity at the bend of the tunnel.
