DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a coal mine underground power supply cable winding device includes a mobile base 1, and a guide wheel is provided under the mobile base 1 to facilitate the movement of the device. It also includes: a wire-releasing mechanism 2 arranged on the mobile base 1; a cable 3 wound on the wire-releasing mechanism 2; a wire-winding mechanism 4 arranged at the front end of the wire-releasing mechanism 2; a clamping mechanism 5 arranged under the wire-winding mechanism 4, the clamping mechanism 5 clamps the cable 3; a detection mechanism 6 arranged in the clamping mechanism 5, the detection mechanism 6 checks the damage of the outer skin of the cable 3, and a plurality of trigger switches 61 are provided in the detection mechanism 6; and an alarm mechanism 7 electrically connected to the trigger switch 61.

[0026] The wire-releasing mechanism 2 includes a baffle 21, a winding shaft 22 and a first motor 23. The baffle 21 is arranged at both ends of the movable base 1. The winding shaft 22 is rotatably connected to the baffle 21. The output end of the first motor 23 is fixedly connected to one end of the winding shaft 22. The winding shaft 22 is driven to rotate by the first motor 23, thereby performing the retracting and releasing operation of the cable 3.

[0027] The top of the baffle 21 is detachably connected with a protective cover 211. When the device is used in a coal mine, the outer skin of the cable 3 may be damaged by broken and falling coal slag. The protective cover 211 is arranged above the winding shaft 22. The protective cover 211 can prevent part of the coal slag from falling onto the winding shaft 22, ensuring that no coal slag is squeezed between the cables 3 when the cables 3 are reeled in.

[0028] The cable winding mechanism 4 is used to evenly wind the cable 3 into the winding shaft 22. Figure 2 As shown, the wire-winding mechanism 4 includes a rack rod 41, a sliding block 42, and a threading block 43. The rack rod 41 is fixed between the two baffles 21, the rack rod 41 is arranged parallel to the winding shaft 22, the sliding block 42 is slidably connected to the rack rod 41, and the cable 3 passes through the threading block 43. When the cable 3 is wound, the threading block 43 is moved back and forth by the sliding block 42, and the cable 3 follows the movement. In this way, the cable 3 can be evenly wound around the side wall of the winding shaft 22 while being wound, thereby avoiding the situation where one end of the cable 3 is too high and the other end is too low on the winding shaft 22.

[0029] The sliding block 42 is provided with a notch 421 at one end of the rack rod 41 having teeth, the bottom of the notch 421 is lower than the bottom of the rack rod 41, a second motor 422 is fixedly connected above the notch 421, a gear shaft 423 is fixedly connected to the output end of the second motor 422, the gear shaft 423 is meshed with the rack rod 41, the second motor 422 drives the gear shaft 423 to rotate, and the gear shaft 423 drives the sliding block 42 to move along the rack rod 41.

[0030] like Figure 3 As shown, the clamping mechanism 5 is used to push the detection mechanism 6 to contact the outer wall of the cable 3. The clamping mechanism 5 includes a connecting rod 51, a slide rail 52, a slide bar 53, a first spring 54 and a clamp 55. The connecting rod 51 is arranged below the threading block 43, and the slide rail 52 is arranged on both sides of the connecting rod 51. The extension direction of the slide rail 52 is parallel to the rack rod 41, and the direction of the slide bar 53 is perpendicular to the slide rail 52. The two slide bars 53 are respectively slidably connected to the slide rail 52. The two ends of the first spring 54 are respectively connected to the two slide bars 53. The first spring 54 is in a stretched state. The first spring 54 drives the two slide bars 53 Approaching the middle, the front end of the clamp 55 is a semicircular ring, and the front end of the clamp 55 clamps the cable 3. After the front ends of the two clamps 55 are attached, there is a gap between the inner wall of the clamp 55 and the outer wall of the cable 3. The clamp 55 does not affect the movement of the cable 3. The rear end of the clamp 55 is a square rod, and there is a latch at the rear end of the clamp rod. The front end of the slide 53 has a socket, and there is a threaded hole on the socket. The latch can be inserted into the socket. After the latch is inserted into the socket, the bolt is screwed in. The bottom of the bolt presses the side wall of the latch, and the movement of the latch is limited by friction, so that the clamp 55 moves with the slide 53. When winding cables 3 of different diameters, the bolt can be loosened and the clamp 55 of the corresponding size can be replaced.

[0031] like Figure 4As shown, the detection mechanism 6 also includes a shell 62, a detection rod 63 and a second spring 64. A plurality of shells 62 are evenly arranged and embedded in the front end of the clamp 55. A blind hole 621 is provided in the shell 62. The trigger switch 61 is provided at the bottom of the blind hole 621. The rear end of the second spring 64 is fixedly connected to the side of the trigger switch 61. The front end of the second spring 64 is fixedly connected to the rear end of the detection rod 63. The detection rod 63 is slidably connected to the blind hole 621. Multiple detection rods 63 can fully detect the side wall of the cable 3. When the clamp 55 is placed on the side wall of the cable 3, the front end of the detection rod 63 contacts the side wall of the cable 3, and the side wall of the cable 3 squeezes the rear end of the detection rod 63 to press the trigger switch 61. At this time, the second spring 64 is in a compressed state. When the cable 3 is reeled in, the cable 3 slides with the front end of the detection rod 63. When the cable 3 is damaged, a pit appears on the side wall of the cable 3. When the pit contacts the detection rod 63, the detection rod 63 moves toward the cable 3 under the push of the second spring 64. At this time, the rear end of the detection rod 63 disengages from the trigger switch 61, and the trigger switch 61 is activated after being disengaged from the squeezing of the detection rod 63. After the trigger switch 61 is activated, the alarm mechanism 7 starts to work.

[0032] The alarm mechanism 7 includes a controller 71 and an alarm 72. The trigger switch 61 is electrically connected to the controller 71, and the controller 71 is electrically connected to the alarm 72 and the first motor 23. When the damage of the cable 3 is detected, the trigger switch 61 is activated, and the controller 71 receives a signal. The controller 71 activates the alarm 72 to start an alarm to remind the staff that the cable is damaged. At the same time, the controller 71 cuts off the power supply of the first motor 23 and stops the winding work, so that the staff can locate the damage.

[0033] A brush 8 is provided below the connecting rod 51 , and the brush 8 cleans the dust on the side wall of the cable 3 , thereby reducing dust pollution on the reeled cable 3 .
