Description

Technical Field

[0001] The utility model relates to a cable traction auxiliary device, in particular to a two-way cable traction device in a mine. Background Art

[0002] At present, when mobile equipment in mines is working, the cables need to be hung on the roof of the tunnel, and the excess cables need to be reeled on the equipment body. Special personnel are arranged to place the cables near the equipment in the tunnel or reel them on the equipment as the equipment moves back and forth.

[0003] This method requires additional staff to adjust the position of the cables and monitor the status of the cables at all times. The work efficiency is low and the equipment needs to be stopped during operation, which affects normal operation.

[0004] At the same time, when people are reeling cables, there is a risk of falling from the equipment. When the cables are thick, multiple people are needed to cooperate in reeling the cables, which requires more people. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model proposes a two-way cable traction device in a mine.

[0006] The device comprises: a fixed wheel 1 and a fixed wheel 2 fixedly installed in a mine tunnel, a traction rope wrapped around the outer diameters of the fixed wheel 1 and the fixed wheel 2, and a transmission mechanism capable of driving the fixed wheel 1 to rotate, thereby driving the traction rope to move;

[0007] Several cable hooks are suspended on one side of the traction rope. Counting along the arrangement direction, the first or last cable hook is the traction cable hook, with its upper portion fixedly connected to the traction rope. The remaining cable hooks are auxiliary cable hooks, with their upper portions slidingly connected to the traction rope and their lower portions connected to the cable to be towed. The traction cable hooks drive the cable to move along with the traction rope, capable of reciprocating the cable along the direction of the traction rope. The remaining auxiliary cable hooks provide auxiliary support for the cable, ensuring that the cable does not rub against the inner wall of the mine during movement.

[0008] Furthermore, the lower parts of the traction cable hook and the auxiliary cable hook are quick hooks, and the quick hooks are fixedly connected to the cables.

[0009] Furthermore, a claw assembly is provided on the upper part of the traction cable hook, which includes: a left claw and a right claw, a bolt assembly passing through the left claw and the right claw, the left claw and the right claw are respectively clamped on the outer contour of the traction rope, and the bolt assembly ensures that the left claw and the right claw remain in a clamped state.

[0010] Furthermore, in order to ensure that the auxiliary cable hook can slide freely along the traction rope, a sliding wheel group is provided on the upper part of the auxiliary cable hook, and the sliding wheel group includes: an upper roller located above the traction rope, a lower roller located below the traction rope, and a clamping plate assembly for accommodating the upper roller and the lower roller.

[0011] Furthermore, an anti-collision block is provided on the outside of the traction cable hook, and a limit block is provided on the outside of the auxiliary cable hook at the other end. The anti-collision block and the limit block are both fixedly installed in the mine tunnel. The anti-collision block prevents the traction cable hook from colliding with the fixed wheel one, and the limit block prevents the auxiliary cable hook from colliding with the fixed wheel two.

[0012] Furthermore, both the anti-collision block and the limit block are provided with a U-shaped groove, the upper part of the U-shaped groove is stuck in the outer contour of the traction rope, and the bottom of the U-shaped groove is provided with a supporting wheel, and the incoming and outgoing ends of the cable both pass through the U-shaped groove above the supporting wheel.

[0013] Furthermore, a coaxial transmission wheel that rotates at the same speed as the fixed wheel is provided above the fixed wheel. The transmission mechanism includes: a reduction motor, a pulley installed at the output end of the reduction motor, and a transmission belt wrapped around the pulley and the outer diameter of the coaxial transmission wheel.

[0014] The technical effects of the present invention are as follows: during construction in a mine, for mobile equipment that requires cable power supply, the present device can drive excess cable to move forward or backward with the equipment. The device uses the power output by the reduction motor on the transmission mechanism to drive the fixed wheel 1 to rotate through the transmission belt, thereby driving the traction rope to move around the fixed wheel 1 and the fixed wheel 2. The traction cable hook suspended below the traction rope provides traction for the cable movement, and the remaining auxiliary cable hooks are mainly used to support the excess cable length to prevent the cable from rubbing back and forth on the ground and getting entangled. Secondly, during the movement of the traction rope, the cable can be pulled or pushed in both directions along the arrangement direction of the traction rope, and the cable can be pulled to various positions, which is convenient for the use of construction equipment and changes the "free traction" method in the prior art. In particular, in some sloping mine tunnels, it can prevent all the cables from being gathered at the end with a lower fixed point of the traction rope due to the action of gravity. Thirdly, during the cable traction process, in order to prevent the outermost cable hooks at both ends from colliding with the fixed wheel 1 and the fixed wheel 2, anti-collision blocks and limit blocks are respectively provided.

[0025] Figure 2 The structure of the upper part of the traction cable hook is illustrated. The upper part of the traction cable hook 5 is provided with a claw assembly 52. The claw assembly 52 includes: a left claw and a right claw, and a bolt assembly 53 passing through the left claw and the right claw. The left claw and the right claw are respectively clamped on the outer contour of the traction rope 4. The bolt assembly 53 ensures that the left claw and the right claw remain in a clamped state.
