Description

Technical Field

[0001] This utility model belongs to the field of coal mining technology, specifically relating to an emergency braking device for an aerial passenger transport device in a coal mine. Background Technology

[0002] In coal mining operations, overhead personnel carriers are important transportation equipment that connects various underground work areas and ensures the passage of miners. Their operational safety is directly related to the safety of miners' lives.

[0003] The emergency braking devices of existing aerial work platforms in coal mines have complex braking triggering methods. Some devices require the operator to operate multiple parts or apply a large force to trigger the braking. In emergency situations, the operator may panic and cause braking delays. At the same time, the chair is subjected to uneven force during braking. Most devices only have a braking structure on one side, which makes the chair prone to tilting and shifting during braking, increasing the risk of injury to the operator. Utility Model Content

[0004] The purpose of this utility model is to provide an emergency braking device for an aerial passenger transport device in a coal mine, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An emergency braking device for an elevated passenger transport system in a coal mine includes an elevated passenger transport mechanism. The elevated passenger transport mechanism includes a chairlift, the top of which is provided with an end cap, a holding cable device is installed inside the end cap, and an emergency braking mechanism is provided on the side of the end cap. Both sides of the end are fixedly installed with a fixed frame, and the inside of the fixed frame is provided with a storage groove. The emergency braking mechanism includes a brake block. The end of the brake block is connected to the inside of the storage groove through a rotating shaft. An extension block is provided at one end of the brake block near the rotating shaft. A sleeve is slidably installed on the surface of the hanging chair near the top. A connecting component is provided on the side of the sleeve and connected to the extension block.

[0006] In a preferred embodiment of this utility model, the connecting assembly includes an extension block, which is fixedly installed on the top of the sleeve. A Y-shaped connecting frame is fixedly provided on the top of the extension block, and the top of the Y-shaped connecting frame respectively cooperates with the two extension blocks.

[0007] In a preferred embodiment of this utility model, the surface of the extension block is provided with a movable groove, the top of the Y-shaped connecting frame is provided with a recess, the recess is movably fitted onto the surface of the extension block, a connecting column is fixedly installed inside the recess, and the surface of the connecting column movably passes through the movable groove.

[0008] As a preferred embodiment of this utility model, the hanging chair has an inner groove near the top, and a through groove is provided at the end of the inner groove, which penetrates the hanging chair. A connecting plate is movably arranged inside the inner groove, and a protruding block is provided at the end of the connecting plate, which is fixedly connected to the sleeve.

[0009] In a preferred embodiment of this utility model, a spring is provided inside the inner groove, and the top end of the spring is fixedly connected to the connecting plate.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[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] Example Reference Figure 1-4 This embodiment of the present invention provides an emergency braking device for an aerial passenger transport device in a coal mine, including an aerial passenger transport mechanism 1. The elevated passenger transport mechanism 1 includes a chairlift, with a head 2 at the top of the chairlift, a cable-holding device installed inside the head 2, and an emergency braking mechanism on the side of the head 2. Fixed frames 6 are fixedly installed on both sides of end 2. The fixed frames 6 have storage slots 7 inside. The emergency braking mechanism includes a brake block 8. The end of the brake block 8 is connected to the inside of the storage slot 7 through a rotating shaft. An extension block 9 is provided at the end of the brake block 8 near the rotating shaft. A sleeve 3 is slidably installed on the surface of the hanging chair near the top. A connecting component is provided on the side of the sleeve 3 to connect with the extension block 9.

[0019] In use, when encountering an emergency, the passenger can pull down the sleeve 3 by hand. The sleeve 3 slides down and pulls the extension block 9 at the rear of the brake block 8 through the connecting component on its side. Since the middle part of the brake block 8 is fixed in the storage groove 7 of the fixed frame 6 through the pivot, the brake block 8 acts as a lever. When one end of its extension block 9 is pulled down, the other end will quickly rise up around the pivot and pop out of the storage groove 7. The upwardly popped brake block 8 forms a protruding stop arm. When the chair continues to move forward under the traction of the wire rope to the nearest rope pulley position, this stop arm will have a violent mechanical collision and interference with the sturdy and fixed rope pulley bracket. Since the rope pulley bracket is fixed and the chair has forward inertial kinetic energy, the forced interference between the two will instantly generate huge resistance, forcing the chair to stop urgently at the rope pulley position.

[0020] In summary, this emergency braking device enables rapid connection between manual operation by the occupant and braking action. In case of emergency, the occupant only needs to pull down the sleeve 3. With the help of the lever principle, the brake block 8 can quickly pop out from the storage slot 7 around the pivot to form a stop arm. Then, it will mechanically interfere with the fixed rope wheel bracket. The fixedness of the bracket and the inertial kinetic energy of the chair will generate huge resistance, instantly forcing the chair to stop. The entire braking process does not require complicated operation and responds in a timely manner.

[0021] Furthermore, the connecting assembly includes an extension block 4, which is fixedly installed on the top of the sleeve 3. A Y-shaped connecting frame 5 is fixedly provided on the top of the extension block 4. The top of the Y-shaped connecting frame 5 cooperates with two extension blocks 9 respectively. An movable groove 10 is provided on the surface of the extension block 9. A groove 11 is provided on the top of the Y-shaped connecting frame 5. The groove 11 is movably fitted on the surface of the extension block 9. A connecting post 12 is fixedly installed inside the groove 11. The surface of the connecting post 12 movably passes through the movable groove 10.

[0022] When in use, when the occupant pulls down the sleeve 3, the extension block 4 and the Y-shaped connecting frame 5, which are fixedly connected to the sleeve 3, also move downward as a whole. The groove 11 at the top of the Y-shaped connecting frame 5 is connected to the extension block 9. When the Y-shaped frame moves downward, the connecting post 12 in the groove 11 will generate a downward pressure and tension on the upper inner wall of the movable groove 10 on the extension block 9. Since the extension block 9 is part of the brake block 8, and the middle part of the brake block 8 is fixed by the pivot, this downward force forms a torque that forces the brake block 8 to rotate upward around its pivot. As an integral component, the Y-shaped connecting frame 5 can ensure that its two top branches pull down the extension blocks 9 on the two brake blocks 8 at the same time and with the same amplitude, thereby realizing the synchronous and symmetrical ejection of the left and right brake blocks 8 and ensuring the balance of force during braking.

[0023] Furthermore, the hanging chair has an inner groove 13 near the top, and a through groove 14 is provided at the end of the inner groove 13. The through groove 14 passes through the hanging chair. A connecting plate 16 is movably arranged inside the inner groove 13. A protrusion is provided at the end of the connecting plate 16. The protrusion is fixedly connected to the sleeve 3. A spring 15 is arranged inside the inner groove 13. The top of the spring 15 is fixedly connected to the connecting plate 16.

[0024] In use, when the occupant needs to brake urgently, they can hold and pull down the sleeve 3. The sleeve 3, through its protrusion, drives the connecting plate 16 to compress the spring 15 downward in the inner groove 13. At this time, the elastic force of the spring 15 is converted into resistance, providing tactile feedback to the operator, while storing elastic potential energy. This downward movement is transmitted through the connecting component, eventually causing the brake block 8 to lift up and enter the braking preparation state. When the emergency is over, or when the brake needs to be reset after completion, the occupant only needs to release the sleeve 3. At this time, the compressed spring 15 begins to release its stored elastic potential energy and rebounds upward. The top of the spring 15 pushes the connecting plate 16 to move upward. The connecting plate 16 pushes the sleeve 3 through the protrusion, causing it to automatically slide back to the initial highest position along the trajectory of the through groove 14. The return of the sleeve 3, through the connecting component, causes the extension block 9 of the brake block 8 to rise, causing the brake block 8 to rotate downward around the axis and retract into the storage groove 7. The entire device returns to the standby state.

[0025] Furthermore, the outer diameter of the sleeve 3 is set to be suitable for the user's grip, and the surface of the sleeve 3 is provided with anti-slip texture.

[0026] In emergency and potentially chaotic situations underground, crew members may slip due to wearing gloves, sweat, or coal dust on their hands. The anti-slip texture design is directly aimed at this real-world working condition, greatly increasing friction and ensuring that the palm does not slip between the palm and the sleeve 3. This allows the crew member to pull down the trigger device successfully in one go with all their might, avoiding operational failures caused by slippage.

[0027] Furthermore, when the brake block 8 is in operation, the end of it furthest from the rotating shaft tilts upward at an angle of 30°.

[0028] When in use, the 30° tilt angle is sufficient to ensure that the end of the brake block 8 can engage with the fixed structure on its movement path. This angle is neither too small to cause braking failure due to rubbing against the top, nor too small to provide sufficient interference depth to withstand impact and achieve effective braking.
