Technical Field
[0001] This utility model relates to the field of automatic circulating hanging chair technology, and in particular to an automatic circulating hanging chair anti-reverse mechanism. Background Technology
[0002] An automatic circulating chairlift is a type of personnel transport device, typically installed on an aerial cableway system. It automatically circulates along a fixed track or rope, achieving efficient personnel transport. Its operation does not require manual pushing of each chair; instead, a power unit drives the circulating system, allowing the chairlifts to continuously travel back and forth between the starting and ending points. In the coal mining industry, chairlifts are commonly known as "monkey cars" and are used to assist in transporting workers.
[0003] Commonly used monkey carts include friction-type detachable monkey carts, which consist of a U-shaped buckle, a hanging axle, and a hanging chair installed through the hanging axle. They can be hung on the wire and moved along the wire by friction.
[0004] When existing friction-type detachable hanging chairlifts are used on steep uphill slopes, the chairlifts may slip and back due to insufficient friction at the connection between the U-shaped buckle and the wire, leading to safety hazards and affecting the efficiency of workers riding the chairlifts. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automatic circulating hanging chair anti-reverse mechanism, which aims to improve the problem that in the existing technology, when the monkey chair is running on a steep uphill slope, it is easy to slip and reverse due to insufficient friction, which causes safety hazards and reduces the efficiency of workers riding the chair.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic circulating hanging chair anti-reverse mechanism, including a support column, a mounting frame provided on one side of the outer wall of the support column, a connecting plate fixedly connected to one side of the outer wall of the mounting frame, a mounting column fixedly connected to the lower surface of the connecting plate, a mounting block fixedly connected to one side of the outer wall of the mounting column, an anti-reverse component for preventing the hanging chair from retracting installed on one side of the outer wall of the mounting block, and a reset component for returning the anti-reverse component to its original position installed on the other side of the outer wall of the mounting block;
[0007] The anti-reverse assembly includes a rotating shaft, one end of which is fixedly connected to one side of the outer wall of the mounting block. A rotating sleeve is rotatably connected to one side of the outer wall of the rotating shaft. A limit block is threadedly connected to one side of the outer wall of the rotating shaft. A fixing rod is fixedly connected to one side of the outer wall of the mounting block. An anti-reverse claw is provided on the lower surface of the rotating sleeve, and a cable is provided on the lower surface of the anti-reverse claw.
[0008] Furthermore, the reset assembly includes a mounting plate, one side of the outer wall of the mounting plate is fixedly connected to one side of the outer wall of the mounting block, a sleeve is fixedly connected to one side of the outer wall of the mounting plate, a spring is fixedly connected inside the sleeve, a sliding block is fixedly connected to one end of the spring, and one side of the outer wall of the sliding block is slidably connected to the inner wall of the sleeve.
[0009] Furthermore, a positioning post is fixedly connected to the lower surface of the rotating sleeve, a second spring is provided inside the positioning post, and locking blocks are fixedly connected to both sides of the second spring.
[0010] Furthermore, the anti-reverse claw has a positioning hole inside.
[0011] Furthermore, one side of the outer wall of the positioning post is slidably connected to the inner wall of the positioning hole, one end of the locking block is slidably connected to the inside of the anti-reverse claw, and one side of the outer wall of the locking block is slidably connected to the inside of the positioning post.
[0012] Furthermore, a guide wheel is slidably connected inside the mounting column, and a nut is threadedly connected to one end of the guide wheel.
[0013] Furthermore, one side of the outer wall of the guide wheel is in contact with one side of the outer wall of the cable, and one side of the outer wall of the nut is in contact with one side of the outer wall of the mounting column.
[0014] Furthermore, a hanging chair body is slidably connected to one side of the outer wall of the cable.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, the anti-reverse claw in the anti-reverse component can give way above the cable as the rotating sleeve rotates around the pivot when the chair is moving forward normally. When the chair body shows a tendency to retreat, the anti-reverse claw will promptly lock the cable under the action of the fixing rod, thus preventing the chair body from retreating. This solves the problem in the prior art that the monkey car is prone to slipping and retreating when running on a steep uphill slope, which causes safety hazards and reduces the efficiency of workers riding the chair. This improves the practicality of the device.
[0017] 2. In this utility model, the anti-reverse claw and the rotating sleeve are connected by a positioning post, a second spring, and a locking block. When the anti-reverse claw is worn or damaged, the locking block is pressed to overcome the elastic force of the second spring until it disengages from the anti-reverse claw, thus realizing the replacement and maintenance of the anti-reverse claw. This is simple and convenient, reduces downtime, and solves the problem that the existing anti-reverse claw is usually fixed by welding, which is more troublesome to replace when damaged, increases downtime, and thus affects the efficiency of the device. Therefore, the practicality of the device is improved. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 and Figure 2This utility model provides an embodiment of an automatic circulating chairlift anti-reverse mechanism, including a support column 1, which ensures the anti-reverse mechanism is firmly installed in the aerial cableway system. A mounting frame 3 is provided on one side of the outer wall of the support column 1, serving to transmit force and fix the position. A connecting plate 4 is fixedly connected to one side of the outer wall of the mounting frame 3, providing an installation plane for the mounting column 5, ensuring the vertical installation of the mounting column 5, and allowing components such as guide wheels 6 installed on the mounting column 5 to accurately engage with the cable 2. The mounting column 5 is fixedly connected to the lower surface of the connecting plate 4. A mounting block 8 is fixedly connected to one side of the outer wall of the mounting column 5. A backstop component for preventing the chair chair from retracting is installed on one side of the outer wall of the mounting block 8, and a reset component for returning the backstop component to its original position is installed on the other side of the outer wall of the mounting block 8. The backstop component includes a rotating shaft 15, which allows the rotating sleeve 13 to rotate flexibly around it, thereby driving the backstop pawl 14 to lift and lower. One end of the rotating shaft 15 is fixedly connected to one side of the outer wall of the mounting block 8, and the rotating sleeve 13 is rotatably connected to one side of the outer wall of the rotating shaft 15. When the chair chair moves forward normally, it can rotate around the rotating shaft 15 as the chair chair moves. 5. Rotation causes the anti-reverse pawl 14 to yield. When the chair swing returns, it works together with the anti-reverse pawl 14 to prevent the chair swing from returning, in cooperation with the fixing rod 12. A limit block 16 is threadedly connected to one side of the outer wall of the rotating shaft 15, which prevents the rotating sleeve 13 from axially displacing along the rotating shaft 15 during rotation, ensuring the positional accuracy and stability of the anti-reverse pawl 14 during operation. A fixing rod 12 is fixedly connected to one side of the outer wall of the mounting block 8, which blocks the clockwise rotation of the anti-reverse pawl 14 when the chair swing returns. The lower surface of the rotating sleeve 13 is provided with the anti-reverse pawl 14. The lower surface of the anti-reverse claw 14 is provided with a cable 2. The reset assembly includes a mounting plate 9. One side of the outer wall of the mounting plate 9 is fixedly connected to one side of the outer wall of the mounting block 8. A sleeve 10 is fixedly connected to one side of the outer wall of the mounting plate 9. A spring 11 is fixedly connected inside the sleeve 10. One end of the spring 11 is fixedly connected to a sliding block 18. One side of the outer wall of the sliding block 18 is slidably connected to the inner wall of the sleeve 10. When the anti-reverse claw 14 rotates, it is compressed and stores elastic potential energy. After the chair passes by, the elastic potential energy is released, pushing the sliding block 18, thereby driving the anti-reverse assembly to return to its original position.
[0026] Reference Figure 1 , Figure 3 and Figure 4A positioning post 20 is fixedly connected to the lower surface of the rotating sleeve 13, which cooperates with the positioning hole 19 of the anti-reverse claw 14 to connect the anti-reverse claw 14 and the rotating sleeve 13. A second spring 21 is installed inside the positioning post 20, and locking blocks 17 are fixedly connected to both sides of the second spring 21. The second spring 21 provides elastic force to the locking blocks 17, allowing the locking blocks 17 to be tightly locked between the anti-reverse claw 14 and the positioning post 20, achieving a reliable connection between the anti-reverse claw 14 and the rotating sleeve 13. A positioning hole 19 is opened inside the anti-reverse claw 14. One side of the outer wall of the positioning post 20 is slidably connected to the inner wall of the positioning hole 19, and one end of the locking block 17 is slidably connected inside the anti-reverse claw 14. One side of the outer wall is slidably connected to the inside of the positioning column 20. The inside of the mounting column 5 is slidably connected to the guide wheel 6. The guide wheel 6 supports and guides the cable 2, reducing the shaking and deviation of the cable 2 during operation. One end of the guide wheel 6 is threadedly connected to the nut 7. By rotating the nut 7, the position of the guide wheel 6 in the mounting column 5 can be adjusted to accommodate cables 2 of different diameters or tensions. One side of the outer wall of the guide wheel 6 is in contact with one side of the outer wall of the cable 2. One side of the outer wall of the nut 7 is in contact with one side of the outer wall of the mounting column 5. The chair body 22 is slidably connected to one side of the outer wall of the cable 2. The chair body automatically circulates by relying on the cyclical movement of the cable 2.
[0027] Working principle: During normal operation, the chair body 22 moves forward under the traction of the cable 2. Due to the forward thrust of the chair, the anti-reverse pawl 14 rotates counterclockwise around the shaft 15 above the cable 2 along with the rotating sleeve 13. At this time, the anti-reverse pawl 14 lifts up to make way for the chair body 22, allowing the chair to pass smoothly through the anti-reverse mechanism and continue forward. During the rotation of the rotating sleeve 13, the cooperation of the sleeve 10 and the spring 11 allows the anti-reverse pawl 14 to quickly retract, preventing jamming due to rust or other reasons, which would prevent timely retraction and thus the anti-reverse effect. When the chair body 22 retracts, it applies a backward pushing force to the anti-reverse pawl 14. This force causes the rotating sleeve 13 to rotate clockwise, making the anti-reverse pawl 14 contact the fixing rod 12. The fixing rod 12 prevents the anti-reverse pawl 14 from continuing to rotate, thus achieving the anti-reverse effect. Finally, when the anti-reverse pawl 14 wears out and becomes damaged, the locking block 17 is pressed to overcome the elastic force of the second spring 21 until it disengages from the anti-reverse pawl 14, thus enabling the replacement and maintenance of the anti-reverse pawl 14. This reduces downtime and improves the overall operating efficiency and economy of the automatic circulating chair system.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
