[0002] A mine hoist is a large piece of machinery used to transport personnel, ore, and materials between underground mines and the surface. The braking system, a crucial component of a mine hoist, comprises both a working brake and a safety brake. The working brake typically utilizes a disc brake, which uses friction between friction pairs to control the hoist's deceleration and stopping. Multiple disc brakes are evenly distributed around the brake disc, which is connected to the drum. The safety brake is used in emergency situations, such as when the hoist overspeeds or overwinds, to quickly stop the hoist and ensure the safety of personnel and equipment.
[0003] During the operation of the existing brake unit, the active unit will generally be damaged to a considerable extent after emergency braking, and during the repair process of the elevator, the damaged components will be locked and clamped, which is very unfavorable for subsequent repair and disassembly. Utility Model Content
[0004] In order to make up for the above deficiencies, the present invention provides an anti-slip clamping device for a mine hoist that overcomes the above technical problems or at least partially solves the above problems.
[0005] The utility model is achieved in this way:
[0006] The utility model provides an anti-slip clamping device for a mine hoist, comprising a connecting frame, a column is provided on the side of the connecting frame, an anti-slip mechanism is provided between the connecting frame and the column, and the anti-slip mechanism comprises:
[0007] A special-shaped plate, wherein a through slot is formed on the special-shaped plate, a force-bearing shaft is provided in the through slot on the special-shaped plate, a tooth plate is provided at the end of the force-bearing shaft, and a first gear and a second gear meshing with each other are provided on one side of the special-shaped plate through a movable shaft;
[0008] An eccentric wheel, wherein the inner ring of the eccentric wheel is provided with a lever arm, and the inner ring of the eccentric wheel is provided with an eccentric shaft located at a non-center part thereof through the lever arm, and the eccentric shaft is movably connected to the special-shaped plate, and the eccentric wheel is mirror-symmetrically arranged on the front side of the special-shaped plate, and the column is arranged between the two eccentric wheels.
[0009] In one embodiment of the present invention, the connecting frame is connected to the structural frame of the elevator, and the upright column is connected to the bottom of the main body of the elevator.
[0010] In one embodiment of the present invention, the main body of the column is provided with openings arranged linearly from top to bottom, and the openings are adapted to the size and shape of the telescopic rod.
[0011] In one embodiment of the present invention, a release mechanism is provided on the side of the anti-slip mechanism, and the release mechanism includes a first mounting plate, one side of the first mounting plate is connected to the end of the force-bearing shaft, and the other side of the first mounting plate is connected to the side of the connecting frame.
[0012] In one embodiment of the present invention, a second mounting plate is provided on the upper portion of the first mounting plate, a mirror-image limiting column is movably inserted into the plate body of the second mounting plate, and the bottom of the limiting column is fixedly connected to the first mounting plate.
[0013] In one embodiment of the present invention, the plate body of the first mounting plate is provided with a threaded shaft rotatably through a bearing, the shaft body of the threaded shaft is threadedly connected to the second mounting plate, and a nut is fixedly connected to the top of the threaded shaft.
[0014] In one embodiment of the present invention, a telescopic rod is provided on one side of the second mounting plate.
[0015] In one embodiment of the present invention, the outer ring of the eccentric wheel is provided with tooth grooves, and both sides of the column are provided with a rough coating.
[0016] The utility model provides an anti-slip clamping device for a mine hoist, which has the following beneficial effects:
[0017] 1. By setting up an anti-skid mechanism, the eccentric wheel of the anti-skid mechanism will clamp the two sides of the column after emergency braking. Combined with the rough coating applied on the column, after the hoist falls, the eccentric wheel will destroy the coating and continue to contact the body of the column, forming the required braking anti-skid effect. At the same time, in the subsequent repair process, the surface of the column can be re-sprayed with a rough coating to reuse the brake components, which is conducive to repair and disassembly work.
[0018] 2. By setting up a release mechanism, when repairing, you only need to insert the telescopic rod into the opening of the column and rotate the threaded shaft. Since the anti-slip mechanism and the release mechanism are not fixedly connected but clamped and overlapped, you can directly steal the inner hoop and rotate the threaded shaft to lift the first mounting plate and the force-bearing shaft, so that the eccentric wheel releases the pressure on the column. Further, install a rotary wrench on the nut to loosen the brake mechanism on the spot, which is convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example
[0026] Reference Figure 1-Figure 4The present technical solution provides an anti-skid clamping device for a mine hoist, which includes a connecting frame 1, a column 101 is provided on the side of the connecting frame 1, an anti-skid mechanism 2 is provided between the connecting frame 1 and the column 101, and the anti-skid mechanism 2 includes: a special-shaped plate 201, an eccentric wheel 206, a through groove is provided on the special-shaped plate 201, a force-bearing shaft 202 is provided in the through groove on the special-shaped plate 201, a tooth plate 203 is provided at the end of the force-bearing shaft 202, a first gear 204 and a second gear 205 that mesh with each other are provided on one side of the special-shaped plate 201 through a movable shaft, a force arm 2062 is provided on the inner ring of the eccentric wheel 206, and the eccentric wheel 2 The inner ring of 06 is provided with an eccentric shaft 2061 located at its non-center part through the force arm 2062. The eccentric shaft 2061 is movably connected to the special-shaped plate 201. The eccentric wheel 206 is mirror-symmetrically arranged in front of the special-shaped plate 201. The column 101 is arranged between the two eccentric wheels 206. When the elevator is operating normally, the original force-bearing shaft 202 will not move the special-shaped plate 201 downward during the rising process. During the normal uniform descent process, the force-bearing shaft 202 and the special-shaped plate 201 also move at a uniform speed and are relatively stationary. Therefore, the anti-slip mechanism 2 does not work. When the elevator falls, the force-bearing shaft 202 will generate downward acceleration. At this time, the special-shaped plate 201 has no downward acceleration, so the toothed plate 203 will move downward relative to the special-shaped plate 201. Under the meshing action of the toothed plate 203, the first gear 204 and the second gear 205 are linked to rotate and the eccentric wheel 206 is rotated, and finally the two eccentric wheels 206 clamp the two sides of the column 101 to produce a braking effect. When releasing the brake, it is only necessary to insert the telescopic rod 305 into the opening 1011 of the column 101 and rotate the threaded shaft 304. Since the anti-slip mechanism 2 and the release mechanism 3 are not fixedly connected but clamped and overlapped, the inner hoop hook can be directly used to rotate the threaded shaft 3 04 Lift the first mounting plate 301 and the force-bearing shaft 202 so that the eccentric wheel 206 releases its pressure on the column 101. By setting the anti-skid mechanism 2, the eccentric wheel 206 of the anti-skid mechanism 2 will clamp the two sides of the column 101 after emergency braking. Combined with the rough coating applied on the column 101, after the hoist falls, the eccentric wheel 206 will destroy the coating and continue to contact the body of the column 101, forming the required braking anti-skid effect. At the same time, in the subsequent repair process, the surface of the column 101 can be re-sprayed with a rough coating so that the brake components can be reused, which is conducive to repair and disassembly work.
[0027] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the connecting frame 1 is connected to the structural frame of the elevator, and the column 101 is connected to the bottom of the main body of the elevator.
[0028] Reference Figure 1-Figure 4Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the main body of the column 101 is provided with openings 1011 arranged linearly from top to bottom, and the openings 1011 are adapted to the size and shape of the telescopic rod 305.
[0029] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a release mechanism 3 is provided on the side of the anti-slip mechanism 2, and the release mechanism 3 includes a first mounting plate 301, one side of the first mounting plate 301 is connected to the end of the force-bearing shaft 202, and the other side of the first mounting plate 301 is connected to the side of the connecting frame 1. By setting the release mechanism 3, when repairing, it is only necessary to insert the telescopic rod 305 into the opening 1011 of the column 101 and rotate the threaded shaft 304. Since the anti-slip mechanism 2 and the release mechanism 3 are not fixedly connected but clamped and overlapped, the inner hoop can be directly used to rotate the threaded shaft 304 to lift the first mounting plate 301 and the force-bearing shaft 202, so that the eccentric wheel 206 releases its pressure on the column 101, and further install a rotary wrench on the nut 3041 to loosen the brake mechanism on the spot, which is convenient to operate.
[0030] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a second mounting plate 302 is provided on the upper part of the first mounting plate 301, and a mirror-image limiting column 303 is movably inserted on the plate body of the second mounting plate 302, and the bottom of the limiting column 303 is fixedly connected to the first mounting plate 301.
[0031] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the plate body of the first mounting plate 301 is provided with a threaded shaft 304 through a bearing rotation, the shaft body of the threaded shaft 304 is threadedly connected to the second mounting plate 302, and the top of the threaded shaft 304 is fixedly connected with a nut 3041. Further, a rotating wrench is installed on the nut 3041, so that the brake mechanism can be loosened on the spot, saving force.
[0032] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a telescopic rod 305 is provided on one side of the second mounting plate 302. When releasing the brake, it is only necessary to insert the telescopic rod 305 into the opening 1011 of the column 101 and rotate the threaded shaft 304. Since the anti-slip mechanism 2 and the release mechanism 3 are not fixedly connected but clamped and overlapped, the threaded shaft 304 can be directly rotated by stealing the inner hook to lift the first mounting plate 301 and the force-bearing shaft 202, so that the eccentric wheel 206 releases its pressure on the column 101.
[0033] Reference Figure 1-Figure 4Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the outer ring of the eccentric wheel 206 is provided with a tooth groove, and both sides of the column 101 are provided with a rough coating, so that it can be re-sprayed during subsequent repairs to continue to provide an anti-slip function.
[0034] Specifically, the working process or working principle of the anti-skid clamping device of the mine hoist is as follows: when the hoist is operating normally, the original force-bearing shaft 202 will not move the special-shaped plate 201 downward during the rising process, and during the normal uniform descent process, the force-bearing shaft 202 and the special-shaped plate 201 also move at a uniform speed and are relatively stationary, so the anti-skid mechanism 2 does not work. When the hoist falls, the force-bearing shaft 202 will generate downward acceleration. At this time, the special-shaped plate 201 has no downward acceleration, so the tooth plate 203 will move downward relative to the special-shaped plate 201, and the tooth plate 203 will mesh with the special-shaped plate 201. Under the action of the pulley 202, the first gear 204 and the second gear 205 are linked to rotate and the eccentric wheel 206 is rotated, and finally the two eccentric wheels 206 clamp the two sides of the column 101 to produce a braking effect. When releasing the brake, it is only necessary to insert the telescopic rod 305 into the opening 1011 of the column 101 and rotate the threaded shaft 304. Since the anti-slip mechanism 2 and the releasing mechanism 3 are not fixedly connected but clamped and overlapped, the inner hoop can be directly used to rotate the threaded shaft 304 to lift the first mounting plate 301 and the force-bearing shaft 202, so that the eccentric wheel 206 releases its pressure on the column 101.
[0035] It should be noted that the threaded shaft 304 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
