[0002] Coal, as my country's primary energy source, is crucial to the development of the national economy. It not only guarantees energy security but is also an important raw material for industrial production. Paste backfilling mining technology is one of the important methods of backfilling mining. This technology involves processing solid waste generated during coal mining, such as coal gangue, fly ash from power plants, and industrial slag, into a slurry-like backfill material. This material is then pressurized by a dedicated backfilling pump and transported to the underground working face via backfilling pipelines. Currently, during coal mining, the mine shaft gradually extends forward. Paste backfilling is used to fill the already mined sections of the shaft. The placement and traction of the isolation fabric are crucial steps in paste backfilling. Traditionally, the placement and traction of the isolation fabric are done manually, resulting in low automation and a slow placement rate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, those skilled in the art who have not made any innovative embodiments are all within the protection scope of the present utility model.

[0024] To achieve the traction function of this device, a traction mechanism for a coal mine paste-filled isolation cloth is proposed, combined with... Figure 1-6 The system consists of a support 1, a track 2, a slider 3, and an isolation cloth 4. The track 2 is fixedly installed at the upper end of the support 1. Multiple sliders 3 are slidably installed inside the track 2. Each slider 3 is equipped with a clamping mechanism. The upper clamping plate 307 and the lower clamping plate 308 in the clamping mechanism are movably installed inside the slider 3. The upper clamping plate 307 and the lower clamping plate 308 clamp one end of the isolation cloth 4. The isolation cloth 4 is rolled up. A rubber strip 401 is fixedly installed at the upper end of the isolation cloth 4. The inner surface of the isolation cloth 4 is fitted onto the surface of the rotating column 5. A base 501 is rotatably installed at the lower end of the rotating column 5. The base 501 is set on the ground. The other end of the isolation cloth 4 is detachably connected to the rotating column 5.

[0025] The isolation cloth 4 can rotate around the rotating column 5 under the pull of the clamping mechanism.

[0026] The clamping mechanism includes: a motor 301, a gear 302, a mounting shell 303, and an electric push rod 312. The motor 301 is fixedly installed inside the slider 3, and a concave mounting area is provided inside the slider 3. The output shaft of the motor 301 is fixedly connected to the gear 302. The gear 302 meshes with the rack 201. The rack 201 is fixedly installed inside the track 2. The track 2 and rack 201 on one support 1 are in contact with the track 2 and rack 201 on another support 1, thereby connecting multiple tracks 2 and multiple racks 201. The multiple tracks 2 and multiple racks 201 form a straight line so that the slider 3 can move on the track 2 and multiple racks 201, thereby splicing the entire track 2 and rack 201. The mounting shell 303 is fixedly installed on one outer end of the slider 3. The controller 304 is fixedly installed inside the mounting shell 303. The controller 304 is electrically connected to the motor 301 and signal connected to the electric push rod 312.

[0027] Limit blocks are installed on the outermost track 2 to limit the maximum movement distance of slider 3.

[0028] Only the first group of sliders 3 has a controller 304, while the other sliders 3 do not. The controller 304 is an existing PLC controller, which is controlled by a remote control, thereby controlling the start and stop of the motor 301 and the extension and retraction of the electric push rod 312.

[0029] The motor 301 provides power for the rotation of the gear 302. The rack 201 is fixed in position, so the gear 302 will move forward. A pulley is provided at the part where the lower end of the slider 3 connects to the track 2 to reduce the friction between the slider 3 and the track 2, thereby driving the slider 3 to slide in the track 2.

[0030] The first movable arm 305 and the second movable arm 306 are rotatably mounted inside the mounting housing 303. The second movable arm 306 has a rectangular notch in the middle, and the inner surface of the notch is in contact with the outer surface of the first movable arm 305. The width of the second movable arm 306 is greater than that of the first movable arm 305. The first movable arm 305 and the second movable arm 306 can rotate inside the mounting housing 303.

[0031] The lower clamping plate 308 is fixedly installed at the end of the first movable arm 305 away from the slider 3. The lower clamping plate 308 is in contact with the lower surface of the rubber strip 401 in the isolation cloth 4. The upper clamping plate 307 is fixedly installed at the end of the second movable arm 306 away from the slider 3. The upper clamping plate 307 is in contact with the upper surface of the rubber strip 401 in the isolation cloth 4.

[0032] The rubber strip 401 on the isolation cloth 4 is fixed by the upper clamping plate 307 and the lower clamping plate 308 in the first set of sliders 3.

[0033] The outer walls of the first movable arm 305 and the second movable arm 306 at the intersection are respectively in contact with the first top block 309 and the second top block 310. The first top block 309 is located near the slider 3. One end of the first toggle rod 311 is fixedly connected to the side of the first top block 309. The other end of the first toggle rod 311 extends out of the mounting shell 303 and its surface is slidably mounted on the side wall of the mounting shell 303. One side surface of the first top block 309 is in contact with the outer surface of the first movable arm 305 and the second movable arm 306.

[0034] To achieve the self-limiting function of the first actuating lever 311, two top blocks 601 are slidably installed on the outer end of the first actuating lever 311 extending out of the mounting shell 303. The top blocks 601 have a triangular cross-section. A sliding area of ​​the top blocks 601 is provided inside the first actuating lever 311. One end of the spring 603 is fixedly connected to the lower end of the top blocks 601, and the other end of the spring 603 is fixedly connected to the first actuating lever 311. The spring 603 is sleeved on the surface of the telescopic rod 604. One end of the telescopic rod 604 is fixedly connected to the top blocks 601, and the other end of the telescopic rod 604 is fixedly connected to the first actuating lever 311. The surface of the top blocks 601 is in contact with the toothed rack 602, and the toothed rack 602 is fixedly installed on the side wall of the mounting shell 303.

[0035] First, the rubber strip 401 inside the isolation cloth 4 is manually placed between the upper clamping plate 307 and the lower clamping plate 308 of the first set of sliders 3. Then, the first actuating lever 311 is manually actuated. The first actuating lever 311 is pulled away from the position of slider 3. The first actuating lever 311 drives the first top block 309 to move in the same direction. The first top block 309 applies pressure to the outer surface of the first movable arm 305 and the second movable arm 306, and one end of the first movable arm 305 and the second movable arm 306 rotates accordingly. The intersection position of the first movable arm 305 and the second movable arm 306 changes, the second top block 310 moves closer to the isolation cloth 4, the electric push rod 312 extends under manual pushing force, the distance between the other end of the first movable arm 305 and the other end of the second movable arm 306 shortens, the upper clamping plate 307 and the lower clamping plate 308 clamp and fix the rubber strip 401 on the isolation cloth 4, and then the controller 304 controls the switch to turn on the motor 301, the first set of sliders 3 slides on the track 2, and then pulls the isolation cloth 4 to unfold;

[0036] When the first actuating lever 311 moves, the top block 601 on it moves accordingly. As the top block 601 moves, it is gradually subjected to pressure from the protruding position of the toothed rack 602, and slides into the groove inside the first actuating lever 311. The spring 603 and the telescopic rod 604 shorten. When the top block 601 moves away from the protruding position of the toothed rack 602, the spring 603 and the telescopic rod 604 extend, and the top block 601 slides out of the groove. This process is repeated until the first actuating lever 311 moves to the appropriate position and the top block 601 is locked between the protrusions of the toothed rack 602, thereby restricting the position of the first actuating lever 311.

[0037] After the first set of sliders 3 moves 3 meters within the track 2, the motor 301 inside the first set of sliders 3 is shut off by the controller 304. The rubber strip 401 inside the isolation cloth 4 is then manually placed between the upper clamping plate 307 and the lower clamping plate 308 inside the second set of sliders 3. The first lever 311 inside the second set of sliders 3 is then activated to clamp the rubber strip 401. The motor 301 inside the first set of sliders 3 is then turned on again, and the movement of the first set of sliders 3 drives the movement of the second set of sliders 3. This process continues until the isolation cloth 4 is fully unfolded.

[0038] Of the multiple sets of sliders 3 in this device, only the first set of sliders 3 contains a motor 301 and a gear 302. The first set of sliders 3 is the driving component, while the other sliders 3 are driven components.

[0039] The second top block 310 is located on the side away from the slider 3. The second actuating rod 3111 is fixedly connected to the middle of the second top block 310. One end of the second actuating rod 3111 extends out of the mounting shell 303 and its surface is slidably connected to the side wall of the mounting shell 303. The other end of the second actuating rod 3111 is fixedly connected to the movable rod end of the electric push rod 312. The fixed rod end of the electric push rod 312 is fixedly installed inside the mounting shell 303. One side surface of the second top block 310 is in contact with the outer surface of the first movable arm 305 and the second movable arm 306.

[0040] When the first set of sliders 3 in this device moves to the end of the track 2 away from the rotating column 5, the isolation cloth 4 is fully unfolded. Then, one end of the isolation cloth 4 is unfolded manually so that it completely covers one side of the support 1. After the isolation cloth 4 is fixed by the existing isolation cloth 4 fixing device, the controller 304 controls the electric push rods 312 in all the sliders 3 to shorten the electric push rods 312. The movement of the electric push rods 312 drives the second top block 310 to move. The second top block 310 pushes the first movable arm 305 and the second movable arm 306 to rotate in opposite directions. The second top block 310 applies a pushing force to the surface of the first movable arm 305 and the second movable arm 306. The first top block 309 is pushed accordingly. The cross position of the first movable arm 305 and the second movable arm 306 gradually returns to the starting position. The distance between the upper clamping plate 307 and the lower clamping plate 308 increases, and the rubber strip 401 on the isolation cloth 4 is gradually loosened.

[0041] Multiple protrusions are provided on the surfaces of the upper clamping plate 307 and the lower clamping plate 308. The protrusions can increase the friction between the upper clamping plate 307 and the lower clamping plate 308 and the isolation cloth 4, reducing the risk of the isolation cloth 4 detaching.

[0042] Working principle:

[0043] First, roll up the isolation cloth 4 and put it onto the rotating column 5, and fix one end to the roller. The rotating column 5 is placed on one side of the support 1.

[0044] Then, by manually placing the starting end of the rubber strip 401 inside the isolation cloth 4 between the upper clamping plate 307 and the lower clamping plate 308 of the first set of sliders 3, and then manually moving the first lever 311, the first lever 311 is pulled away from the position of the slider 3. The upper clamping plate 307 and the lower clamping plate 308 clamp and fix the rubber strip 401 on the isolation cloth 4. Then the controller controls the switch of the motor 301 to be turned on, and the first set of sliders 3 slides on the track 2, thereby pulling the isolation cloth 4 to unfold.

[0045] After the first set of sliders 3 moves 3 meters within the track 2, the motor 301 inside the first set of sliders 3 is shut off by the controller 304. The rubber strip 401 inside the isolation cloth 4 is then manually placed between the upper clamping plate 307 and the lower clamping plate 308 inside the second set of sliders 3. The first lever 311 inside the second set of sliders 3 is then activated to clamp the rubber strip 401. The motor 301 inside the first set of sliders 3 is then turned on again, and the movement of the first set of sliders 3 drives the movement of the second set of sliders 3. This process continues until the isolation cloth 4 is fully unfolded.

[0046] Finally, when the first set of sliders 3 in this device moves to the end of the track 2 away from the rotating column 5, the isolation cloth 4 is fully unfolded. Then, one end of the isolation cloth 4 is manually unfolded so that it completely covers one side of the support 1. After the isolation cloth 4 is fixed by the existing isolation cloth 4 fixing device, the controller 304 controls the electric push rods 312 in all the sliders 3 to shorten the electric push rods 312. The movement of the electric push rods 312 drives the second top block 310 to move, the distance between the upper clamping plate 307 and the lower clamping plate 308 increases, and the rubber strip 401 on the isolation cloth 4 is gradually loosened, completing the unfolding of the isolation cloth 4. The controller 304 controls the motor 301 to move in the opposite direction and pushes the remaining sliders 3 back to the starting position through the first set of sliders 3. 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 variations 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.
