Description

Technical Field

[0001] This utility model belongs to the technical field of high-altitude installation devices, and relates to a descent device, particularly a descent device anti-panic device. Background Technology

[0002] A descent device is an emergency escape equipment specifically designed for workers operating at heights. It controls the descent speed through mechanical braking (such as friction wheels or hydraulic damping) to help construction, cleaning, and maintenance personnel safely descend to the ground in case of platform malfunction or sudden danger. Its core components consist of a high-strength cut-resistant rope, an automatic speed-regulating mechanism, and a full-body safety harness.

[0003] When working at heights, factors such as rope wear, operational errors, rapid shifts in the center of gravity, and loose anchor points can cause short-distance sudden drops. Sudden drops are an acceleration process, and the feeling of falling can cause panic and other emotions in the user. In addition, the instantaneous impact load generated by sudden drops is large, which can easily create safety hazards. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a simple-to-operate, strong-locking anti-panic device for a descent device.

[0005] The purpose of this utility model can be achieved through the following technical solution: a descent device for preventing panic, characterized in that it includes a descent body with an internal rope reel, a drive shaft at the center of the rope reel, an anti-panic device on the side wall of the descent body, a follower turntable and a locking disc on the anti-panic device, the follower turntable being engaged with the drive shaft, the follower turntable having a plurality of locking pawls, the follower turntable having a plurality of limiting locking ratchet teeth on the optical axis, the inner wall of the locking disc having a plurality of concave teeth, a counterweight protrusion at one end of the locking ratchet tooth, and a limiting groove at the other end of the locking ratchet tooth, and a spring between the limiting groove and the follower turntable.

[0006] In the aforementioned anti-panic device for a descent device, the follower turntable is provided with an end cap, and the follower turntable is provided with several limiting links. The end cap is provided with several limiting holes, and the optical axis and the limiting links are both placed in the limiting holes. A fixed bearing is provided on one side of the end cap.

[0007] In the aforementioned anti-panic device for a descent device, a sealing cover is provided on one side of the locking disc, and the sealing cover is provided with several locking bolts.

[0008] In the aforementioned anti-panic device for a descent device, the main body of the descent device has several shaft holes A on its side wall, the locking plate has a shaft hole B through which the shaft passes, and the sealing cover has a shaft hole C. The shaft holes A, B, and C are coaxially arranged, and a fixing locking pin is provided in the shaft hole A. The fixing locking pin is inserted into the shaft holes B and C.

[0009] Compared to existing technologies, this descent device's anti-panic mechanism utilizes the high-speed rotation during a sudden descent to cause a locking ratchet with a counterweight protrusion to engage with the concave teeth, thereby locking the rope reel and increasing safety. A spring allows the locking ratchet to easily reset, simplifying operation. The fixed locking block pin increases connection strength, making the structure more stable and reducing bolt bending, thus preventing difficulties in assembly and disassembly.

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1-5As shown, the anti-panic device 3 of this descent device includes a descent body 2 with an internal rope reel 8. A drive shaft 9 is located at the center of the rope reel 8. An anti-panic device 3 is installed on the side wall of the descent body 2. The anti-panic device 3 has a follower turntable 14 and a locking disc 16. The follower turntable 14 is engaged with the drive shaft 9. The follower turntable 14 has several locking pawls 11 and several optical shafts 12 limiting the locking pawls 11. The inner wall of the locking disc 16 has several concave teeth 10. A counterweight protrusion 17 is located at one end of each locking pawl 11. The other end is provided with a limiting groove 15. A spring 13 is provided between the limiting groove 15 and the follower turntable 14. During use, the follower turntable 14 rotates with the rope reel 8. If it slides and falls, or if the rope is misinstalled, the locking error will occur. The rope reel 8 will rotate at high speed due to rope friction. The locking pawl 11 will swing due to inertia until it contacts the concave tooth 10. The concave tooth 10 and the locking pawl 11 will engage and lock, preventing further fall. When unlocking, the rope is pulled to rotate the follower turntable 14 in the opposite direction. The concave tooth 10 and the locking pawl 11 will disengage and reset under the action of the spring 13, and the descent device will operate normally.

[0018] Preferably, the follower turntable 14 is provided with an end cap 19, and the follower turntable 14 is provided with a plurality of limiting links 18. The end cap 19 is provided with a plurality of limiting holes 21. The optical shaft 12 and the limiting links 18 are both placed in the limiting holes 21. A fixed bearing 22 is provided on one side of the end cap 19. The end cap 19 limits and locks the pawl 11 to prevent it from falling off.

[0019] Preferably, a sealing cover 4 is provided on one side of the locking disc 16, and a number of locking bolts 1 are provided on the sealing cover 4.

[0020] Preferably, the main body 2 of the decelerator has several shaft holes A20 on its side wall, the locking plate 16 has a shaft hole B through which the shaft passes, and the sealing cover 4 has a shaft hole C7. The shaft holes A20, B6, and C7 are coaxially arranged, and a fixing locking pin 5 is provided in the shaft hole A20. The fixing locking pin 5 is inserted into the shaft hole B6 and the shaft hole C7. During installation, the fixing locking pin 5 is first placed in the shaft hole A20, and then the locking plate 16 and the sealing cover 4 are assembled in sequence. By limiting the position of the fixing locking pin 5, the bolts of the anti-panic device 3 are reduced due to excessive force, and the installation strength is increased.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0022] Although this document frequently uses terms such as locking bolt 1, decelerator body 2, anti-panic device 3, sealing cover 4, fixing locking block pin 5, shaft hole B 6, shaft hole C 7, rope reel 8, drive shaft 9, concave tooth 10, locking pawl 11, optical shaft 12, spring 13, follower turntable 14, limiting groove 15, locking disc 16, counterweight protrusion 17, limiting link 18, end cap 19, shaft hole A 20, limiting hole 21, and fixing bearing 22, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
