High-altitude abseiling device and abseiling system

Abstract

The invention provides a high-altitude abseiling device. The high-altitude abseiling device comprises a main body 1, a self-locking cam 2, a press rod 3, an upper lock pin 4, a rotary shaft 6, a reset spring 7 and a lower lock pin 8, wherein the main body comprises a U-shaped storage groove 11 and a load board 13. An upper pin hole 18 and a lower pin hole 16 are formed on the storage groove 11, the upper lock pin 4 and the lower lock pin 8 are respectively inserted into the upper pin hole 18 and the lower pin hole 16 in use, a cam support 12 and a hook hole 14 are formed on the load board 13, and the self-locking cam 2 is installed on the cam support 12 through the rotary shaft 6 in a pivoted mode. The upper end of the press rod 3 is installed on the upper lock pin 4 in the pivoted mode, and a poking block 35 is installed at the lower end of the press rod 3 in the pivoted mode and abuts against a protruding block 21 on the self-locking cam 2 during working, so that the self-locking cam 2 is away from the storage groove 11. The reset spring 7 installed on the rotary shaft 6 acts on the self-locking cam 2 to enable the self-locking cam 2 to trend to extrusion toward the storage groove 11. The high-altitude abseiling device has the advantages of being simple in operation, high in abseiling efficiency, safe, self-locking and labor-saving. The invention further provides an abseiling system.

Description

technical field [0001] The patent application of the present invention relates to a device for safely descending along a rope during emergency escape from high-altitude buildings or field high-altitude operations, especially a labor-saving, self-locking high-altitude rope descent device, and a rope descent system. Background technique [0002] Modern buildings tend to be higher and higher. People usually use elevators to go up and down from high-rise buildings. However, in case of emergency, such as fire and earthquake, the elevator may not be used. How to let people in high places quickly and safely Landing from a high-rise or a high altitude to the ground is a problem faced by many engineers and technicians in the safety of high-rise buildings. There are many patented technologies in this respect. For example, CN1047809A discloses a high-rise escape safety controller. For the fixed brake wheel and a pair of brake handle brake wheels, the speed of the user sliding down the ...

Problems solved by technology

[0003] In order to overcome the disadvantages of low efficiency, high requirements for use conditions, and incapability of self-locking in emergency situations in the prior art, the present invention provides a high-altitude rope descent device, which includes a main body, a self-locking cam, a pressing bar, a locking Pin, rotating shaft, return spring and lower locking pin. The main body includes a U-shaped storage slot and a load plate. The storage slot has an upper pin hole and a lower pin hole. When in use, the upper pin hole and the lower pin hole are respectively inserted into the upper locking pin. and the lower lock pin, the load plate has a cam bracket and a hook hole, the self-locking cam is pivotally mounted on the cam bracket through the rotating shaft, the upper end of the pressure rod is pivotally mounted on the upper lock pin, and the lower end is pivotally mounted with a shifting block. The shift block presses the projection on the self-locking cam, so that the self-locking cam tends to stay away from the storage groove; the return spring installed on the rotating shaft acts on the self-locking cam, so that the self-locking cam has a tendency toward The Trend of Storage Slot Extrusion
