[0029] Herein Figs. 1-3To describe an embodiment of a mine monkey car on and off the track speed reducer device. Specifically, the mine monkey car on and off the track speed reducer device is configured as a split structure, which has a track guide bar 100, a cable holder 200 transmission mechanism 300 and the like. When the cable 400 drives the cable holder 200 to approach the track guide bar 100 from either end, the lower wheel 203 moves smoothly along the lower end surface of the track guide bar 100, and the track guide bar 100 continuously presses the lower wheel 203 to move downward, until the clamping structure 202 releases the clamping of the cable 400, and the cable holder 200 falls on the transmission mechanism 300. After that, the cable holder 200 and the monkey car are slowly moved by the transmission mechanism 300, so that the lower wheel 203 continues to move along the track guide bar 100. During the process of slowly moving the cable holder 200 and the monkey car by the transmission mechanism 300, the speed of the monkey car is reduced, which facilitates workers to get on and off the monkey car and improves the safety when getting on and off the monkey car.
[0030] Please refer to Figs. 1-3 A mine monkey car on and off the track speed reducer device, comprising a track guide bar 100 and a cable holder 200.
[0031] The cable holder 200 comprises a support body 201, and a clamping structure 202 for clamping the cable 400 is installed on the support body 201. The clamping structure 202 is provided with a lower wheel 203 at the end away from the cable 400.
[0032] The plane where the track guide bar 100 is located is parallel to the segment of the cable 400 close to the track guide bar 100. When the cable 400 drives the cable holder 200 to approach the track guide bar 100 from either end, the lower wheel 203 can move smoothly along the lower end surface of the track guide bar 100. During the movement, the clamping structure 202 releases the clamping of the cable 400 when the track guide bar 100 and the lower wheel 203 are in contact. When the lower wheel 203 moves away from the track guide bar 100, the clamping structure 202 clamps the cable 400.
[0033] The transmission mechanism 300 is provided below the track guide bar 100, and the conveying direction of the transmission mechanism 300 is parallel to the plane where the track guide bar 100 is located.
[0034] When the lower wheel 203 moves along the track guide bar 100, the cable holder 200 is always located above the transmission mechanism 300, and the lower end surface of the cable holder 200 is in contact with the upper end surface of the conveying end of the transmission mechanism 300.
[0035] It should be noted that the rope holder 200 is a prior art, which can adopt the rope holder 200 described in the Chinese patent "Balance control device and method of the unhooking rope holder 200 of the cable car" with patent application number CN202411503548.8. The rope holder 200 should also be provided with a spring, which is used to move the lower pressing wheel 203 upwards and reset when the lower pressing wheel 203 moves away from the rail-changing guide strip 100, so that the clamping structure 202 clamps and fixes the cable 400 again. Since it adopts the prior art, the specific structure of the rope holder 200 will not be described in detail in this application.
[0036] It should be noted that the cable 400 is arranged in the mine through a guide frame, the rail-changing guide strip 100 can be fixed on the sidewall of the mine, and the conveying mechanism 300 is installed and arranged on the sidewall of the mine or the guide frame. The monkey car is fixed and hung below the rope holder 200 through the connecting piece. When the rope holder 200 moves to the conveying mechanism 300, the rope holder 200 moves from the upper end of the conveying mechanism 300, and the monkey car moves from below the conveying mechanism 300. Therefore, the connecting piece can be designed to be curved to avoid interference of the conveying mechanism 300 with the connecting piece during movement.
[0037] The rail-changing guide strip 100 and the conveying mechanism 300 are arranged at positions where workers need to get on and off the car in the mine. When the cable 400 drives the rope holder 200 to approach the rail-changing guide strip 100 from either end, the lower pressing wheel 203 moves smoothly along the lower end surface of the rail-changing guide strip 100, and the rail-changing guide strip 100 continuously presses the lower pressing wheel 203 to move downward, so that the clamping structure 202 releases the clamping of the cable 400, and the rope holder 200 falls on the conveying mechanism 300. Thereafter, the conveying mechanism 300 conveys the rope holder 200 and the monkey car slowly, so that the lower pressing wheel 203 continues to move along the rail-changing guide strip 100. During the slow movement of the conveying mechanism 300 conveying the rope holder 200 and the monkey car, the speed of the monkey car is reduced, so that the workers can get on and off the monkey car easily, and the safety during getting on and off the monkey car is improved.
[0038] When the conveying mechanism 300 conveys the rope holder 200 and the monkey car to move to the other end of the rail-changing guide strip 100, the clamping structure 202 clamps and fixes the cable 400 again.

[0041] In order to improve the guiding property of the conveying mechanism 300 to the cable gripper 200, the conveying mechanism 300 further comprises a pair of symmetrically arranged limiting baffles 303, which are respectively attached to the two sides of the annular conveying belt 302 along the axis direction of the rotating rollers 301, the limiting baffles 303 are rotationally sleeved at the two ends of the rotating rollers 301, and the upper end of the limiting baffles 303 is higher than the upper end face of the annular conveying belt 302; through the arrangement of the limiting baffles 303, the cable gripper 200 can be prevented from accidentally falling off from the two sides of the annular conveying belt 302, and the guiding property during movement can be improved.
[0042] In order to facilitate the movement of the annular conveying belt 302, the conveying mechanism 300 further comprises a first rotating shaft 304, which is fixedly connected with any rotating roller 301 and coaxially arranged with the rotating roller 301, a first gear 305 is fixedly sleeved on the first rotating shaft 304, any limiting baffle 303 is rotationally connected with a second rotating shaft 306 which is coaxially arranged with the first rotating shaft 304, a second gear 307 is fixedly sleeved on the second rotating shaft 306, an annular synchronous toothed belt 308 is sleeved between the first gear 305 and the second gear 307, and a driven wheel 309 is fixedly sleeved on the second rotating shaft 306, and the peripheral wall of the driven wheel 309 is in contact with the cable 400.
[0043] During the pulling of the cable 400, the cable drives the driven wheel 309, the driven wheel 309 drives the second rotating shaft 306, the second gear 307, the annular synchronous toothed belt 308, the first gear 305, the first rotating shaft 304, the rotating roller 301 and the annular conveying belt 302 in sequence, thereby facilitating automatic control of the conveying mechanism 300 to the cable gripper 200.
[0044] The diameter of the first gear 305 is greater than the diameter of the second gear 307; so as to reduce the conveying speed of the conveying mechanism 300, realize deceleration and facilitate workers to get on and off the vehicle.
[0045] In order to make the conveying direction of the conveying mechanism 300 the same as the pulling direction of the cable 400, the driven wheel 309 is located below the cable 400, and the upper peripheral wall of the driven wheel 309 is in extrusion contact with the cable 400; so as to control the conveying direction of the conveying mechanism 300 to be consistent with the pulling direction of the cable 400.
[0046] The coaxial annular groove 3091 is arranged on the peripheral wall of the driven wheel 309, and the cable 400 is in extrusion contact with the peripheral wall of the annular groove 3091; the annular groove 3091 is arranged to increase the friction between the cable 400 and the driven wheel 309.
