High-rise escape self-rescue lifter

Abstract

The invention provides a high-rise escape self-rescue lifter which comprises a shell, a rope collecting wheel, an axle, a retracting rope, a hook, a rocker arm driving rod, a driving gear, a handle and a safety belt. The-rise escape self-rescue is characterized in that the shell consists of two concave shells which are symmetrically arranged; an axle through hole is formed in the rope collecting wheel; the axle penetrates through the axle through hole, and two ends of the axle are positioned on two sides of the rope collecting wheel; fixing holes are correspondingly formed in the two concave shells; two ends of the axle penetrate through the fixing holes; a disc spring is arranged on the axle on two sides of the rope collecting wheel; fastening nuts arranged at two ends of the axle are screwed; and the disc spring is pressed between the rope collecting wheel and the concave shells. The high-rise escape self-rescue lifter has the advantages that the design is scientific, the operation is convenient and initial drop speed is slow, the escape personnel is easily held, the speed is manually controlled, the retracting rope is not worn by the buildings, and the safety belt is safe and reliable.

Description

technical field [0001] The invention relates to an escape device, in particular to a high-rise escape self-rescue lifter used for escape in high-rise buildings. Background technique [0002] At present, when a fire breaks out in a high-rise building, people often use the landing device when they choose to escape from the window. As an escape article, the landing device itself must be safe and reliable. However, existing falling devices have disadvantages in actual use, such as: the initial falling speed is uncontrolled, and the falling speed is faster and faster due to the influence of the acceleration of gravity, causing the fall; The result is that the escape personnel cannot get down; because the return rope is stuck by the building during the ascent process, the escape personnel are suspended on the way to escape, and the landing device cannot be reused; The independent setting makes it inconvenient for people to perform speed control operations during the process of fa...
