Description
Technical Field
[0001] This utility model relates to the field of coal mine gantry crane technology, and in particular to a coal mine gantry crane anti-collision device. Background Technology
[0002] The coal mine "monkey car," officially known as a mine aerial ropeway, is a specialized piece of equipment used to assist in the transportation of workers in underground mines. Its purpose is to shorten the travel time for miners to and from the mine in a more convenient, faster, and less strenuous way, while also reducing the physical exertion during these journeys, allowing miners to dedicate more energy to their work underground. The main component of the coal mine "monkey car" is the chairlift, which forms the main load-bearing structure and supports the miner's weight. At the top of the chairlift, a gripping device is installed. The function of the rigging device is to connect tightly with the wire rope, ensuring that the chairlift can be stably attached to the wire rope and move smoothly along the roadway as the wire rope moves. A seat is also installed on the chairlift bend for workers to sit on. At the bottom of the chairlift bend, there is a footrest. When using the coal mine hoist, the miner first sits on the seat on the chairlift bend, with his feet placed stably on the footrest. Then, he is connected to the wire rope through the rigging device. As the wire rope moves, the chairlift moves the miner quickly along the roadway, thus enabling the miner to go up and down the mine quickly.
[0003] During the use of mine caravans, guardrails are usually installed on both sides of the mine tunnel to ensure the safety of personnel and equipment. However, the steel wire ropes connecting the mine caravans are prone to deformation during long-term use due to frequent stretching, contraction, and friction with the rope grippers. As the mine tunnel extends deeper, its cross-sectional dimensions often gradually narrow. In this case, when workers ride the caravan, the distance between their footrests and the guardrails on both sides of the mine tunnel will decrease accordingly. During the operation of the caravan, if the deformation of the steel wire rope causes instability in the running trajectory, the footrests are likely to collide with the guardrails. This collision will generate a large impact force, causing the caravan to shake violently. If the shaking amplitude is large, it may cause passengers to lose their balance or even fall off the caravan, thus causing a serious coal mine safety accident.
[0004] To address the aforementioned problems, this application proposes a collision avoidance device for coal mine monkey trains. Utility Model Content
[0005] Based on the technical problems existing in the background art, this utility model proposes a collision prevention device for coal mine monkey carts.
[0006] This utility model proposes a collision avoidance device for a coal mine monkey car, which includes a monkey car body and a collision avoidance component;
[0007] The main body of the monkey car includes a chair support tube, a foot pedal is installed at the bottom of the chair support tube, and the anti-collision component is installed on the front side of the foot pedal;
[0008] The anti-collision component includes a loading rod and a V-shaped elastic element. The loading rod is detachably installed on the front side of the foot pedal. The end of the loading rod away from the foot pedal is hinged to the V-shaped elastic element, and the V-shaped elastic element deforms to buffer the impact.
[0009] Preferably, the V-shaped elastic element includes a V-shaped rod and a spring. The loading rod has an opening at the end away from the foot pedal. The middle part of the V-shaped rod is inserted into the opening and hinged to the loading rod. Inclined springs are installed on the inner sides of both V-shaped rods, and the two springs are respectively connected to the two sides of the loading rod.
[0010] Preferably, the anti-collision component further includes a screw member, and a through loading hole is provided in the middle of the foot pedal. The screw member is installed at one end of the loading rod and is detachably connected to the loading hole.
[0011] Preferably, the screw component includes a screw body and a nut, one end of the loading rod is fitted with a screw body that passes through the loading hole, and one end of the loading rod abuts against the front side of the foot pedal, and the screw body is threaded with a nut that abuts against the rear side of the foot pedal.
[0012] Preferably, a stool is mounted on the hanging chair support tube via a support rod.
[0013] Preferably, a cable gripper is installed at the top of the chair hanger support tube.
[0014] The above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0015] 1. During use, the cable gripper on the chairlift is connected to the steel wire rope inside the mine. The worker sits on a stool, holds the chairlift with both hands, and steps on the foot pedals. As the steel wire rope moves, the entire trolley moves. During the movement, as the tunnels become narrower as you go deeper into the mine, when the foot pedals collide with the guardrails in the tunnels, the anti-collision components installed at the front of the foot pedals can provide protection. Specifically, when the V-shaped bar on the loading bar collides with the guardrail, because the V-shaped bar is hinged to the loading bar, it can deflect relatively. This deflection can change the direction of the collision force, dispersing the impact force that was originally acting directly on the foot pedals. At the same time, the spring between the V-shaped bar and the loading bar deforms, which can absorb a large amount of impact energy. This buffering mechanism greatly reduces the impact force generated by the collision and avoids the trolley body shaking violently due to the collision.
[0016] 2. Due to the cushioning effect of the anti-collision components, even in the event of a collision, there will be no direct impact injury to the feet of the passengers. This can effectively protect the feet of the passengers and prevent the strong vibrations generated by the collision from being transmitted to the feet, thereby reducing the probability of injury. In addition, the stable riding environment can also reduce the possibility of injuries to other parts of the body caused by shaking. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0023] like Figure 1-4 As shown, the present invention proposes a coal mine monkey car anti-collision device, which includes a monkey car body 1 and an anti-collision component 2;
[0024] The main body 1 of the monkey car includes a chair support tube 101, a foot pedal 102 is installed at the bottom of the chair support tube 101, and a collision protection component 2 is installed on the front side of the foot pedal 102;
[0025] The anti-collision component 2 includes a loading rod 21 and a V-shaped elastic element 22. The loading rod 21 is detachably installed on the front side of the foot pedal 102. The end of the loading rod 21 away from the foot pedal 102 is hinged to the V-shaped elastic element 22, and the V-shaped elastic element 22 deforms to buffer the impact.
[0026] Workers can sit on the hanging chair 101 and step on the foot pedals 102. When moving in the mine roadway, when the V-shaped elastic element 22 in the anti-collision component 2 is impacted, it will deform. In this process, the V-shaped elastic element 22 converts the kinetic energy generated by the impact into elastic potential energy through deformation, thereby buffering the impact force.
[0027] In a specific embodiment, the V-shaped elastic element 22 includes a V-shaped rod 221 and a spring 222. An opening is provided at the end of the loading rod 21 away from the foot pedal 102. The middle part of the V-shaped rod 221 is fitted into the opening and hinged to the loading rod 21. Inclined springs 222 are installed on the inner sides of both V-shaped rods 221, and the two springs 222 are respectively connected to both sides of the loading rod 21. When the V-shaped rod 221 is impacted, it rotates towards the loading rod 21. At this time, the inclined springs 222 on the inner side of the V-shaped rod 221 are compressed. During compression, spring 222 generates elastic force, which is opposite to the direction of the impact force and can offset part of the impact force. At the same time, the deformation of spring 222 can also absorb impact energy. Through the dual action of the rotation of V-shaped rod 221 and the compression of spring 222, the impact energy is more fully dispersed and absorbed, minimizing the impact on the main body 1 of the manhole cover, reducing the swaying amplitude of the manhole cover, providing a more stable riding environment for miners, and preventing V-shaped rod 221 from being damaged due to excessive impact, thus extending the service life of anti-collision component 2.
[0028] In a specific embodiment, the anti-collision component 2 further includes a screw member 23. A through loading hole is provided in the middle of the foot pedal 102. The screw member 23 is installed at one end of the loading rod 21 and is detachably connected to the loading hole. The screw member 23 includes a screw body 231 and a nut 232. A screw body 231 passing through the loading hole is installed at one end of the loading rod 21, and one end of the loading rod 21 abuts against the front side of the foot pedal 102. A nut 232 that abuts against the rear side of the foot pedal 102 is threaded onto the screw body 231.
[0029] When disassembling and assembling the anti-collision component 2 as a whole, after passing the screw body 231 of one end of the loading rod 21 through the loading hole of the foot pedal 102, one end of the loading rod 21 abuts against the front side of the foot pedal 102, which plays a preliminary positioning role. Then, the nut 232 is threaded onto the screw body 231 and the nut 232 is continuously tightened until the nut 232 abuts against the rear side of the foot pedal 102. Through the clamping force between the nut 232 and the loading rod 21, the loading rod 21 is fixed on the foot pedal 102, thus completing the overall installation of the anti-collision component 2. At the same time, during subsequent disassembly and maintenance, the loading rod 21 can be removed simply by unscrewing the nut 232, thus completing the overall disassembly of the anti-collision component 2. The operation is simple and quick.
[0030] In a specific embodiment, a seat 103 is installed on the chair support tube 101 via a support rod 105, providing a comfortable seating support point for miners.
[0031] In a specific embodiment, a cable gripper 104 is installed on the top of the chairlift 101; its internal structure can tightly engage with the wire rope in the mine. Through the friction and clamping force between the cable gripper 104 and the wire rope, the main body 1 of the chairlift is firmly connected to the wire rope. When the wire rope moves under the action of the drive device, the cable gripper 104 will move with the wire rope, thereby driving the entire main body 1 of the chairlift along the roadway. This is the prior art and will not be elaborated further.
[0032] The specific working principle of this utility model is as follows:
[0033] During the use of the coal mine monkey car, the first step is to connect it tightly to the steel wire rope in the mine through the cable gripper 104 at the top of the chair gripper 101. The cable gripper 104 ensures that the main body of the monkey car 1 can be stably attached to the steel wire rope by relying on its own friction and clamping force with the steel wire rope. When the miner rides, he sits on the seat 103 of the chair gripper 101, holds the chair gripper 101 with both hands, and places his feet on the foot pedal 102 at the bottom of the chair gripper 101.
[0034] When the wire rope moves, the entire monkey car body 1 is driven to run along the roadway through the cable gripper 104. As it moves deeper into the mine, the cross-sectional size of the roadway gradually narrows. If the wire rope is deformed due to long-term use, causing the monkey car's running trajectory to become unstable, and the foot pedal 102 is at risk of colliding with the guardrails on both sides of the roadway, the anti-collision component 2 installed on the front side of the foot pedal 102 will play its role in advance.
[0035] When a collision occurs, the V-shaped rod 221 rotates around the hinge point with the loading rod 21. At the same time, the spring 222, which is installed obliquely on the inner side of the V-shaped rod 221, is compressed. During the compression process, the spring 222 generates a reverse elastic force, which offsets part of the impact force. The deformation of the spring 222 and the rotation of the V-shaped rod 221 together absorb the impact energy, greatly weakening the impact force that was originally directly acting on the foot pedal 102, preventing the main body 1 of the manned vehicle from shaking violently. All components work together to achieve safe transportation of miners and effectively avoid collision accidents through the anti-collision component 2, thus ensuring the safety of miners' lives.
[0036] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
