Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable pressing auxiliary device used in underground coal mines. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when excavating geological strata rich in coal. They usually include tunnels, shafts, mining faces, etc. Coal is the most important solid fuel and a type of combustible organic rock.

[0003] Cables are needed in the coal mining process. In order to ensure the convenience of cable transportation and storage, it is usually necessary to reel the cables, that is, to wind the cables around a drum. A cable crimping auxiliary device is required to reel the cables. In the prior art, the existing cable crimping auxiliary device usually adopts manual reeling of the cables, which is time-consuming and labor-intensive. In addition, the cables are easily entangled with each other during the auxiliary reeling process, which greatly reduces the reeling efficiency. In view of this, a cable crimping auxiliary device for use in coal mines is proposed. Utility Model Content

[0035] Furthermore, the second chute 10 is opened on the left surface of the second support rod 9, the sliding rod 11 is slidably sleeved in the inner wall of the second chute 10, and the first wire wheel 13 is fixedly installed on the left end of the sliding rod 11;

[0040] Furthermore, two vertical plates 20 are fixedly mounted on the front surface of the winding workbench 1, and a winding roller 21 is rotatably connected to the opposite surfaces of the two vertical plates 20, and a transmission shaft of the winding roller 21 passes through the left surface of the two vertical plates 20;

[0042] When the cable pressing auxiliary device is used in coal mines, the cable is passed through the second wire wheel 14, the first wire wheel 13 and the ring 19 in sequence and is wound and fixed to the outer surface of the winding roller 21. The cable is wound in a Z shape on the outer surfaces of the first wire wheel 13 and the second wire wheel 14. At this time, by starting the first motor 5, the first motor 5 outputs power to the first threaded rod 4 fixedly installed at the output end through operation, causing it to rotate. At this time, the sliding block 6 threadedly sleeved on the outer surface of the first threaded rod 4 continues to move forward through the thread set on the outer surface of the first threaded rod 4. At the same time, the sliding block 6 drives the fixed rod 7 fixed on the left surface to move forward. At the same time, the fixed rod 7 drives the first support rod 8 with a rotating sleeve on the outer surface to move forward. While the first support rod 8 moves forward, it applies forward pressure to the second support rod 9. At this time, the second support rod 9 rotates on the left surface of the fixed plate 2 and gradually moves upward. While the second support rod 9 moves upward, the sliding rod 11 gradually moves downward on the inner surface of the second slide groove 10. At the same time, the sliding rod 11 drives the left end fixed The first wire-passing wheel 13 installed moves downward, and the third support rod 12 rotates on the outer surface of the sliding rod 11 and is gradually inclined to support the sliding rod 11. At this time, the distance between the first wire-passing wheel 13 and the second wire-passing wheel 14 becomes larger, and the first wire-passing wheel 13 applies pressure on the cable. At this time, the tension on the cable surface is increased by starting the third motor 22. At this time, the third motor 22 outputs power to the winding roller 21 fixedly installed at the output end through operation, causing it to rotate for winding. At the same time of winding, the second motor 17 is started. The second motor 17 outputs power to the second threaded rod 16 fixedly installed at the output end through operation, causing it to rotate. At this time, the moving block 18 threadedly sleeved on the outer surface of the second threaded rod 16 continues to move to the right through the thread set on the outer surface of the second threaded rod 16. At the same time, the moving block 18 drives the ring 19 fixedly installed on the upper surface to move to the right. The ring 19 pulls the cable on the inner surface to gradually move to the right, so that the cable can be evenly laid on the outer surface of the winding roller 21.

[0043] The cable pressing auxiliary device for underground coal mines adjusts the distance between the first wire wheel 13 and the second wire wheel 14 through the first motor 5, and the first wire wheel 13 applies pressure to the surface of the cable, and presses the cable wrapped in a Z shape on the outer surface of the first wire wheel 13 and the second wire wheel 14 to increase its surface tension, which can facilitate subsequent winding and prevent the winding from being too loose and entangled with each other, making it more convenient. The cable pressing auxiliary device for underground coal mines drives the ring 19 to move from left to right in sequence while winding through the second motor 17, the second threaded rod 16 and the moving block 18 to pay out the cable, so that it is evenly laid on the outer surface of the winding roller 21, making the cable laying more even.

[0044] Working principle: When the cable pressing auxiliary device is used in coal mines, the cable is passed through the second wire wheel 14, the first wire wheel 13 and the ring 19 in sequence and is wound and fixed to the outer surface of the winding roller 21. The cable is wound in a Z shape on the outer surfaces of the first wire wheel 13 and the second wire wheel 14. At this time, by starting the first motor 5, the first motor 5 outputs power to the first threaded rod 4 fixedly installed at the output end through operation, causing it to rotate. At this time, the sliding block 6 threadedly sleeved on the outer surface of the first threaded rod 4 continues to move forward through the thread set on the outer surface of the first threaded rod 4. At the same time, the sliding block 6 drives the fixed rod 7 fixedly installed on the left surface to move forward. At the same time, the fixed rod 7 drives the first support rod 8 with a rotating sleeve on the outer surface to move forward. While the first support rod 8 moves forward, it applies forward pressure to the second support rod 9. At this time, the second support rod 9 rotates on the left surface of the fixed plate 2 and gradually moves upward. While the second support rod 9 moves upward, the sliding rod 11 gradually moves downward on the inner surface of the second slide groove 10. The first wire-passing wheel 13 fixedly mounted on the output end moves downward, and the third support rod 12 rotates on the outer surface of the sliding rod 11 and is gradually inclined to support the sliding rod 11. At this time, the distance between the first wire-passing wheel 13 and the second wire-passing wheel 14 becomes larger, and the first wire-passing wheel 13 applies pressure on the cable. At this time, the tension on the cable surface is increased. At this time, the third motor 22 is started, and the third motor 22 outputs power to the winding roller 21 fixedly mounted on the output end through operation, so that it rotates for winding. At the same time, the second motor 17 is started, and the second motor 17 outputs power to the second threaded rod 16 fixedly mounted on the output end through operation, so that it rotates. At this time, the moving block 18 threadedly sleeved on the outer surface of the second threaded rod 16 continues to move to the right through the thread set on the outer surface of the second threaded rod 16. At the same time, the moving block 18 drives the ring 19 fixedly mounted on the upper surface to move to the right, and the ring 19 pulls the cable on the inner surface to gradually move to the right, so that the cable can be evenly laid on the outer surface of the winding roller 21.
