Cable traction tension overload device for coal mining

Abstract

This utility model relates to the technical field of cable traction tension overload devices for coal mining, and in particular to a cable traction tension overload device for coal mining, comprising a base, a support seat on the base surface of the base, and through grooves symmetrically opened on the base surface of the support seat. An adjusting rod is installed inside the through groove, and a rotating seat is installed at the lower end of each adjusting rod. With this cable traction tension overload device, when the cable is subjected to significant pressure, the support rod drives the adjusting rod to move downwards. A buffer spring releases the reserved portion of the cable. Simultaneously, the downward movement of the adjusting rod drives a roller to move outwards inside the base. When the roller reaches the position of the pressure sensor, the pressure sensor detects the pressure, and an alarm sounds, thus reminding the operator to stop traction on the cable to prevent cable breakage. The overall device has a simple structure, is easy to operate, and is highly practical.

Description

Technical Field

[0001] This utility model relates to the technical field of cable traction tension overload device for coal mining, specifically a cable traction tension overload device for coal mining. Background Technology

[0002] Generally, coal mining machines are powered by mining cables. Since coal mining machines need to move back and forth to mine coal, the mining cables used in coal mining machines are mostly laid in cable trenches by cable traction clamps, so that the mining cables can move back and forth with the coal mining machine to maintain the power supply to the coal mining machine.

[0003] As the coal mining machine moves, it maintains traction on the mining cable. When the traction force exerted by the coal mining machine on the mining cable exceeds the maximum value that the mining cable can withstand, the mining cable will be pulled apart, causing a serious electromechanical accident and affecting the safe production and efficient output of the coal mine.

[0004] Therefore, a cable traction overload device for coal mining is needed to improve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cable traction tension overload device for coal mining, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cable traction tension overload device for coal mining includes a base, a support seat on the base surface, and through grooves symmetrically formed on the base surface of the support seat. An adjusting rod is disposed inside each through groove, and a rotating seat is disposed at the lower end of each adjusting rod. A roller is rotatably disposed inside the rotating seat. A pressure sensor is disposed on the right side inside the base. A first connecting rod is disposed on the left side of each adjusting rod, and a second connecting rod is disposed on the right side of each adjusting rod.

[0023] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0024] A cable traction tension overload device for coal mining includes a base 1, a support seat 2 on the base surface of the base 1, and through grooves 3 symmetrically formed on the base surface of the support seat 2. An adjusting rod 4 is installed inside the through grooves 3, and a rotating seat 5 is installed at the lower end of each adjusting rod 4. A roller 6 is rotatably mounted inside the rotating seat 5. A pressure sensor 7 is installed on the right side inside the base 1. A first connecting rod 8 is installed on the left side of the adjusting rod 4, and a second connecting rod 9 is installed on the right side of the adjusting rod 4. Limiting sliders 10 are installed at the outer ends of both the first and second connecting rods 8 and 9. A limiting rod 11 is slidably mounted inside the limiting slider 10, and a buffer spring 12 is sleeved on the outer wall of the limiting rod 11 below the limiting slider 10. A first connecting plate 13 is provided on the left side of the base surface of the support base 2, and a second connecting plate 14 is provided on the right side of the base surface of the support base 2. Limiting grooves 15 are provided on the inner sides of both the first connecting plate 13 and the second connecting plate 14. A first support plate 16 is provided on the left side of the first connecting plate 13, and a second support plate 17 is provided on the right side of the second connecting plate 14. A first guide wheel 18 is provided on the base surface of the first support plate 16. A support rod 19 is provided at the upper end of the adjusting rod 4. A second guide wheel 20 is provided at the upper end of the support rod 19. A third guide wheel 21 is provided on the base surface of the second support plate 17. A cable 22 is provided between the first guide wheel 18, the second guide wheel 20 and the third guide wheel 21. An alarm 23 is provided on the front of the base 1.

[0025] The support base 2 has a U-shaped structure, the roller 6 is located inside the base 1 and is adapted to the base 1, the adjusting rod 4 has a V-shaped structure and is elastic, the limiting rod 11 is located inside the limiting groove 15, and the limiting slider 10 is adapted to the limiting groove 15 so that the limiting slider 10 can slide inside the limiting groove 15. Through the coal mining cable traction tension overload device, when the cable 22 is subjected to a large pressure, the support rod 19 drives the adjusting rod 4 to move downward. The buffer spring 12 can release the reserved part of the cable 22. While the adjusting rod 4 moves downward, it drives the roller 6 to move outward inside the base 1. When the roller 6 moves to the position of the pressure sensor 7, the pressure sensor 7 detects the pressure and the alarm 23 sounds, which can remind the staff to stop pulling the cable 22 to avoid the cable 22 from breaking. The overall device has a simple structure, is easy to operate and has higher practicality.

[0026] The working process of this utility model is as follows: When using the overload device for traction tension of coal mining cables, when the cable 22 is subjected to a large pressure, the support rod 19 drives the adjusting rod 4 to move downward. At the same time, the adjusting rod 4 drives the first connecting rod 8 and the second connecting rod 9 to move downward. When the first connecting rod 8 and the second connecting rod 9 move downward, they drive the limiting slider 10 to move downward, thereby releasing the reserved portion of the cable 22 through the buffer spring 12. When the adjusting rod 4 moves downward, the lower end of the adjusting rod 4 expands outward, and at the same time, it drives the roller 6 to move outward inside the base 1. When the roller 6 moves to the position of the pressure sensor 7, the pressure sensor 7 detects the pressure, and the alarm 23 sounds, thereby reminding the staff to stop traction on the cable 22 to avoid the cable 22 from breaking.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
