Self-locking high-altitude rope descending device and rope descending system

Abstract

The invention provides a self-locking high-altitude rope descending device which comprises a main body 1, a self-locking cam 2 and a friction lever 7, wherein one side edge of the main body 1 is bent into a containing groove 8 used for containing a rope 9; the containing groove 8 is provided with a pin hole; a lock pin 10 is inserted into the pin hole; the main body 1 is provided with a hook hole 3; the self-locking cam 2 and the friction lever 7 are coaxially arranged on the fixed axis 5 positioned on the main body 1; and a spring 4 arranged on the fixed axis 5 acts on the self-locking cam 2 so that the self-locking cam 2 trends to extrude towards the containing groove 8. The self-locking high-altitude rope descending device provided by the invention has the advantages of easiness for operation, wide application range, low usage condition requirement, high rope descending efficiency and self-locking safety. The invention also provides a self-locking rope descending 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 self-locking high-altitude rope descent device, and provides a self-locking 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 d...
