Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically to a cable laying device for electrical equipment in coal mines. Background Technology

[0002] During coal mining, due to the long mine tunnels, cables need to be laid to connect underground electrical equipment. Currently, cable laying construction generally involves transporting coiled cables to the vicinity of the construction site, where workers unroll the coiled cables and then manually clamp them onto a traditional cable conveyor for transmission.

[0003] However, traditional cable conveyors do not have the function of adjusting according to the cable diameter, resulting in low friction between the cable conveyor and smaller cross-section cables, which can lead to slippage. Furthermore, the cable specifications that can be conveyed are limited, resulting in low conveying efficiency of the cable conveyor. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a cable laying device for electrical equipment in coal mines, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a cable laying device for electrical equipment in a coal mine, including a workbench and two sets of conveying components disposed on the workbench. Each set of conveying components is fixedly connected to a limit block at its bottom. A limit opening is provided on the workbench, and the limit block is slidably disposed inside the limit opening. An adjustment component is provided at the bottom of the workbench to drive the two sets of conveying components to move closer or further away simultaneously.

[0006] Preferably, the adjustment assembly includes two supports fixed to the bottom of the workbench and a bidirectional screw rotatably inserted between the two supports. A motor is fixedly installed on the side wall of one of the supports, and the output end of the motor is fixedly connected to the bidirectional screw. Two nut blocks are threaded on the bidirectional screw. A guide rod is fixedly connected between the two supports. The guide rod is movably inserted through the nut blocks, and one end of the nut blocks is fixedly connected to a limiting block.

[0007] Preferably, the limiting opening is a cross-shaped opening, and the limiting block is cross-shaped.

[0008] Preferably, the conveying assembly includes a bottom strip fixed to the top of the limiting block, two pulleys rotatably mounted on the bottom strip, a conveyor belt being sleeved between the two sets of pulleys, and a second motor fixedly mounted on the top of the bottom strip, with the output end of the second motor fixedly connected to one of the pulleys.

[0009] Preferably, a support bar is fixedly connected to the top of the workbench, and a groove is provided on the top of the support bar. Multiple rollers are rotatably arranged between the inner walls of the groove.

[0010] Preferably, both ends of the support bar are provided with ramps.

[0011] This utility model provides a cable laying device for electrical equipment in coal mines, which has the following advantages:

[0012] 1. In this utility model, the starting motor drives the bidirectional screw to rotate, and the bidirectional screw drives the two nut blocks to move closer to each other, thereby driving the two bottom strips to move closer to each other, so that the conveyor belt comes into contact with the cable surface, achieving the purpose of clamping the cable, thus ensuring that the cable can be smoothly conveyed and laid; and meeting the laying requirements of cables of different diameters.

[0013] 2. In this utility model, two motors are started simultaneously. The motors drive the connected pulleys to rotate. With the cooperation of another pulley, the conveyor belt moves. The two moving conveyor belts transport the cable. The conveyor belts are made of rubber, which can reduce the wear and tear when clamping the cable. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 6 This utility model provides a technical solution: a cable laying device for electrical equipment in a coal mine, including a workbench 1 and two sets of conveying components 2 set on the workbench 1. Each set of conveying components 2 is fixedly connected to a limit block 3 at its bottom. A limit port 101 is opened on the workbench 1. The limit block 3 is slidably set inside the limit port 101. An adjustment component 4 is provided at the bottom of the workbench 1 to drive the two sets of conveying components 2 to move closer or further away at the same time.

[0023] The adjustment assembly 4 includes two supports 41 fixed to the bottom of the workbench 1 and a bidirectional screw 43 rotatably inserted between the two supports 41. A motor 45 is fixedly installed on the side wall of one of the supports 41. The output end of the motor 45 is fixedly connected to the bidirectional screw 43. Two nut blocks 42 are threaded on the bidirectional screw 43. A guide rod 44 is fixedly connected between the two supports 41. The guide rod 44 is movably inserted through the nut block 42. One end of the nut block 42 is fixedly connected to the limit block 3.

[0024] The motor 45 is started, which drives the bidirectional screw 43 to rotate. The bidirectional screw 43 drives the two nut blocks 42 to move closer to each other, thereby driving the two bottom strips 21 to move closer to each other, so that the conveyor belt 23 comes into contact with the surface of the cable 7, achieving the purpose of clamping the cable 7, thus ensuring that the cable 7 can be smoothly conveyed and laid; and meeting the laying requirements of cables 7 of different diameters.

[0025] The limiting opening 101 is a cross-shaped opening, and the limiting block 3 is also a cross-shaped opening, which ensures that the limiting block 3 will not fall out from inside the limiting opening 101.

[0026] The conveying assembly 2 includes a bottom strip 21 fixed to the top of the limiting block 3, two pulleys 22 rotatably mounted on the bottom strip 21, a conveyor belt 23 sleeved between the two sets of pulleys 22, and a second motor 24 fixedly mounted on the top of the bottom strip 21. The output end of the second motor 24 is fixedly connected to one of the pulleys 22.

[0027] At the same time, two motors 24 are started, which drive the connected pulley 22 to rotate. With the cooperation of the other pulley 22, the conveyor belt 23 moves, and the two moving conveyor belts 23 transport the cable 7.

[0028] A support bar 5 is fixedly connected to the top of the workbench 1. A groove 51 is opened on the top of the support bar 5. Multiple rollers 6 are rotatably arranged between the inner walls of the groove 51. The cable 7 is placed on the multiple rollers 6. During transportation, the cable 7 moves on the surface of the rollers 6. The rollers 6 and the groove 51 are rotatably connected, which reduces the wear of the cable 7 during transportation.

[0029] Both ends of the support bar 5 are provided with ramps 511. The ramps 511 allow the cable 7 to maintain a smooth transition when entering and exiting the support bar 5, thereby reducing the friction of the cable 7.
