Description

Escape device with controllable descending function

Technical Field

The invention relates to the technical field of descent devices, in particular to an escape device with a controllable descent function.

Background

The most important thing in escape devices is a descent control device, a tool for reducing the descent speed when an escape rope is used, and also a protector for protecting operators (sometimes needing to protect trapped people) in sports (expansion training, mountain climbing, limit, outdoors, etc.), rescue, and the like, which is also called a descent protector; compared with an ascending device, the device strengthens the buffering effect by increasing the friction force to ropes (steel cables and rails), thereby achieving the purpose of slow descending; common descenders are mainly stop descent protectors, 8-rings, multi-function pulleys, etc. Of course, we can also use ropes to wind twice on a common D-shaped safety hook to make a simple descender, which is divided into two types in use: 1. at the operator, i.e. the operator connects the descender to the half (full) body safety belt through a safety hook, and then controls the descending speed through the grip (the descending speed can also be controlled by the person at the end below the rope through tightening the rope and the tension thereof); 2. is at the trapped person. After the rescue personnel connects the descender with the trapped personnel, controlling the descending speed of the trapped personnel by controlling the descending speed of the descender until the trapped personnel safely reaches the ground (safe place); descenders are commonly used in rescue procedures for the rescue of high-level trapped personnel. The descending device in the market is provided with 8-shaped rings, and the angle of the rope needs to be controlled in time when the 8-shaped rings descend, so that people cannot conveniently control the descending speed in time when the people receive external factors.
