Description

Technical Field

[0001] This utility model belongs to the field of aerial passenger transport technology in coal mines, and specifically relates to an aerial passenger transport device for coal mines. Background Technology

[0002] Aerial worker transport systems in coal mines, also known as "monkey cars," are crucial equipment for transporting personnel underground. In coal mining operations, the underground working areas are vast and long, requiring miners to move frequently between different work locations. Traditional walking methods are not only physically and time-consuming but also reduce work efficiency. With the continuous expansion of coal mining scale and the increasing demands for production efficiency, aerial worker transport systems have emerged. They use steel cables to power suspended chairs, allowing miners to move quickly through the tunnels, achieving efficient personnel transportation. The advent of this system has greatly improved the travel conditions for miners underground, providing strong support for safe production and efficient operation in coal mines.

[0003] Currently, in aerial work platforms for personnel transport in coal mines, two sheaves are typically installed. These two sheaves are in close contact with the steel cable from above and below to stabilize and guide its movement. However, in actual use, the underground environment of coal mines is complex and changeable. When encountering falling heavy objects or other emergencies, the external force on the sheaves can suddenly increase, potentially causing them to become unstable and derail. Therefore, this design does not meet the current requirements. To address this, we have proposed an aerial work platform for personnel transport in coal mines. Utility Model Content

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Reference Figures 1-4 This embodiment of the present invention provides an aerial passenger transport device for coal mines, including a steel cable 100, a traveling cylinder 101 slidably disposed on the outside of the steel cable 100, and a seating plate 102 installed on the bottom side of the traveling cylinder 101. A rope-supporting pulley is movably disposed inside the traveling cylinder 101 and slides in cooperation with the steel cable 100. A tensioning mechanism 200 is installed inside the traveling cylinder 101 to adjust the extension of the rope-supporting pulley. The tensioning mechanism 200 includes a connecting cylinder 200a disposed on the inner wall of the traveling cylinder 101, a connecting rod 200b that is slidably fitted inside the connecting cylinder 200a, and an abutting spring 200c installed between the connecting rod 200b and the connecting cylinder 200a. A support frame 300 is installed on the bottom side of the connecting rod 200b, and a connecting shaft 301 is installed inside the support frame 300. The rope-supporting wheel 103 is rotatably sleeved on the surface of the connecting shaft 301. Three sets of rope-supporting wheels 103 are provided, and the three sets of rope-supporting wheels 103 are arranged in a circular row on the inner wall of the traveling cylinder 101, and the three sets of rope-supporting wheels 103 support the steel wire rope 100 at different positions.

[0019] The inner wall of the traveling cylinder 101 is provided with an annular groove 400. Three sets of arc-shaped plates 401 slide inside the annular groove 400. The connecting cylinder 200a is installed on the bottom side of the arc-shaped plates 401. The arc-shaped plates 401 are provided with a sliding groove 402. Two sliders 403 are inserted and slidably fitted inside the sliding groove 402. The two sliders 403 are slidably fitted at both ends of the sliding groove 402.

[0020] A support plate 404 is installed between the sliders 403 on each pair of arc plates 401. The support plate 404 is set as an arc plate 401. A push spring 405 is installed inside the sliding groove 402. The push spring 405 is set between the two sliders 403. A roller 500 is installed on the surface of the arc plate 401. The roller 500 rolls with the inner wall of the annular groove 400. A support rod 501 is installed between the traveling cylinder 101 and the riding plate 102.

[0021] Specifically, during use, the three sets of rope pulleys 103 support the steel wire rope 100 from different positions, forming a triangular fulcrum structure. Triangles typically have unique stability, which helps to make the steel wire rope 100 run more smoothly and reduce swaying and deviation. Furthermore, by installing a tensioning mechanism 200 between the traveling cylinder 101 and the rope pulley 103, when the operator encounters bumps during use, the rope pulley 103 is pushed back into the connecting cylinder 200a by the connecting rod 200b on the contact belt. This provides the rope pulley 103 with a rebound space, effectively buffering the impact of bumps and reducing the possibility of damage to the rope pulley 103 and the steel cable 100 due to sudden and severe vibrations, thus extending the service life of the rope pulley 103 and the steel cable 100. Moreover, the existence of the rebound space ensures that the rope pulley 103 and the steel cable 100 always maintain good contact, reducing the possibility of the rope pulley 103 derailing, thereby improving the safety and stability of the entire overhead passenger transport device.

[0022] Preferably, during use, the steel wire rope 100 may bend or rotate due to force, thus restricting the rope support wheel 103. Due to the sliding fit of the balls between the arc plate 401 and the annular groove 400, the arc plate 401 can rotate adaptively and drive the rope support wheel 103 to rotate together. In this way, the rope support wheel 103 can adaptively adjust its contact point with the steel wire rope 100 according to the bending condition of the steel wire rope 100, improve the stable support of the rope support wheel 103 for the steel wire rope 100, and reduce the wear between the steel wire rope 100 and the rope support wheel 103.

[0023] In summary, the triangular fulcrum structure formed by the three sets of rope-supporting pulleys 103 makes the steel wire rope 100 more stable during operation, minimizing swaying and deviation, and improving the basic stability of the device. The tensioning mechanism 200 effectively buffers the impact of bumps, reducing the possibility of damage to the rope-supporting pulleys 103 and the steel wire rope 100 due to sudden, severe vibrations, thus extending their service life. Furthermore, the cooperation between the connecting cylinder 200a and the connecting rod 200b ensures that the rope-supporting pulleys 103 and the steel wire rope 100 maintain good contact at all times, reducing the risk of derailment of the rope-supporting pulleys 103 and improving the safety and stability of the entire overhead passenger transport device.
