Description

Technical Field

[0001] This utility model relates to a moving cable dragging device for a hydraulic drilling rig in a filling working face. Background Technology

[0002] 1. The original cable of the hydraulic drilling rig at the working face was coiled up using a cable reel rack. After the cable was coiled up, it occupied a lot of space, and personnel could not pass behind the drilling rig, which could easily cause insufficient exit width.

[0003] Second, when the hydraulic drilling rig moves back and forth on the working face, it is necessary to equip a dedicated person to follow the drilling rig to reel in and deploy the cable. This is extremely detrimental to the safety of the cable reeling personnel and the operation of the hydraulic drilling rig. Moreover, if the speed of cable reeling and deployment is inconsistent with the speed of the hydraulic drilling rig, it is very easy to cause scraping and damage to the cable. Especially when the cable insulation is reduced, it is very easy to cause electric shock accidents to the cable reeling and deployment personnel.

[0004] Third, the mobile cable dragging device for coal mining machinery generally uses special cable clamps for connection, which takes up a lot of space, makes cable dragging difficult, and the cable clamps wear out quite severely. The back-and-forth movement of the drilling rig cable can easily damage the cable and cause safety problems.

[0005] Fourth, the remaining space in the cable trough is small, which can easily cause the cable clamps to be scratched during the return of the hydraulic drilling rig, seriously affecting the installation of the hydraulic drilling rig cable clamps.

[0006] 5. As mining progresses, excess cables are stacked on the tail side of the machine face, affecting personnel passage and the safety of the on-site construction environment.

[0007] VI. In order to achieve the requirements of reducing manpower and improving efficiency underground, improve the efficiency of face support operations and reduce the physical labor of employees. Utility Model Content

[0008] The purpose of this invention is to provide a moving cable dragging device for a hydraulic drilling rig in a filling working face, so as to solve the above-mentioned technical problems.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A mobile cable dragging device for a hydraulic drilling rig in a filling working face includes a cable, fixed anchor rods, fixed rope clamps, guide pulleys, hanging rings, thin steel wire ropes, a main body anchoring frame, an anti-pull-out device, connecting bolts, a load-bearing belt, a cable trough, a working face conveyor, and a hydraulic drilling rig. Multiple fixed anchor rods are equidistantly inserted into the wall. Two fixed rope clamps are respectively fixedly connected to the inner sides of the front and rear fixed anchor rods. Multiple guide pulleys are equidistantly fixedly connected to the thin steel wire rope. The hanging ring is fixedly connected below the fixed anchor rods. The thin steel wire rope passes through multiple hanging rings and is fixedly connected between the front and rear fixed rope clamps. The guide pulleys on the thin steel wire rope move the cable back and forth. The connecting bolts anchor the anti-pull-out device to the load-bearing belt and the main body anchoring frame. The cable trough is located on the right side of the working face conveyor, which is fixedly connected to the right side of the hydraulic drilling rig.

[0010] Based on the above technical solution, the working face conveyor includes fixing bolts and a toothed rail. The hydraulic drilling rig is connected to the load-bearing belt through a body anchoring frame, fixing bolts, and an anti-pull-out device. Under the power drive of the hydraulic drilling rig, it realizes reciprocating operation on the toothed rail of the working face conveyor, driving the load-bearing belt to reciprocate within the cable trough. The load-bearing belt protects the cable along the line of action of the connecting bolts, ensuring that the cable is not stressed and is not worn.

[0011] Based on the above technical solution, the load-bearing belt includes a protective belt, which is fixedly connected to the outside of the load-bearing belt.

[0012] Compared with the prior art, the present invention has the following advantages: 1. Ensuring worker safety: Since personnel no longer have direct contact with moving live cables, electric shock accidents are effectively prevented. Simultaneously, the space between the drilling rig and the support is freed up, ensuring the safety of personnel passing through the working face. The implementation of this invention significantly reduces the risk of safety accidents caused by improper human operation, thereby protecting the lives and health of workers.

[0013] 2. Reduced workload and labor intensity: Traditional manual cable relocation requires manual labor, and the workload increases continuously as the drilling rig moves. This is not only time-consuming and labor-intensive but also easily puts a physical burden on employees. The introduction of this utility model will significantly reduce workload, alleviate the physical labor intensity of employees, and improve the comfort of the working environment.

[0014] 3. Improve work efficiency: The automatic operation of the automated and continuous cable dragging device can shorten the time that the support work is affected by the laying of the drilling rig cable, thereby improving the overall work efficiency.

[0015] 4. Achieve cost reduction and efficiency improvement: The application of this utility model will help achieve the goal of cost reduction and efficiency improvement in downhole operations. By reducing manual labor, reducing the investment in cable clamps, shortening operation time, improving operation efficiency, reducing the company's human and material resources investment, and improving overall economic benefits.

Multiple fixed anchor rods 2 are equidistantly inserted into the wall. Two fixed rope clips 3 are respectively fixedly connected to the inner sides of the front and rear fixed anchor rods 2. Multiple guide pulleys 4 are equidistantly... The cable 1 is fixedly connected to the thin steel wire rope 6. The hanging ring 5 is fixedly connected to the bottom of the fixed anchor rod 2. The thin steel wire rope 6 passes through multiple hanging rings 5 ​​and is fixedly connected between the front and rear fixed rope clamps 3. The guide pulley 4 on the thin steel wire rope 6 moves the cable 1 back and forth. The connecting bolt 9 anchors the anti-pull-out device 8 to the load-bearing belt 10 and the main body anchoring frame 7. The cable trough 11 is opened on the right side of the working face conveyor 12. The working face conveyor 12 is fixedly connected to the right side of the hydraulic drilling rig 13.

[0022] The working face conveyor 12 includes fixing bolts 14 and a toothed rail 15. The hydraulic drilling rig 13 is connected to the load-bearing belt 10 through the body rooting frame 7, fixing bolts 14 and anti-pull-out device 8. Under the power drive of the hydraulic drilling rig 13, it realizes reciprocating operation on the toothed rail 15 of the working face conveyor 12, driving the load-bearing belt 10 to reciprocate within the cable trough 11. The load-bearing belt 10 protects the cable 1 along the line of action of the connecting bolt 9, ensuring that the cable 1 is not stressed and is not worn.

[0023] The load-bearing belt 10 includes a protective belt 16, which is fixedly connected to the outside of the load-bearing belt 10.

[0024] The working principle of this utility model is as follows: The hydraulic drilling rig cable is installed into the hydraulic drilling rig's mobile cable towing device in the filling face converted from a waste conveyor belt. It is connected and fixed with bolts to the power inlet of the hydraulic drilling rig. A cable anti-pull-out device is used to connect to the hydraulic drilling rig body. Under the drive of the hydraulic drilling rig, the cable is automatically towed back and forth. Thin steel wire ropes are used to fix the cables to the roadway sidewalls. Small guide pulleys are installed at anchor points every 3 meters along the cables distributed within the roadway. Through the pushing and mining of the working face, the cable slides back and forth, achieving self-movement of the cable along the sidewalls.
