Stop rod type reciprocating high-rise escape device

Abstract

The invention provides a stop rod type reciprocating high-rise escape device which comprises a front shell, a rear shell, a first shaft, a second shaft, a large gear, a small gear, a wave gear, a stop rod, a stop shaft, a guide wheel and a reciprocating escape rope. The front shell and the rear shell are arranged on the outermost, the first shaft is arranged in the front shell and the rear shell, the second shaft is vertically arranged above the first shaft, the large gear is fixedly disposed on the first shaft, the small gear is arranged outside the second shaft, the wave gear is arranged outside the small gear, the stop rod is disposed on the second shaft, the stop shaft is fixedly arranged on the stop rod, the guide wheel is disposed below the large gear, and the reciprocating escape rope penetrates through the guide wheel. The stop rod and the stop shaft are fixed together and move horizontally, and the wave gear is meshed with the stop shaft. The stop rod type reciprocating high-rise escape device is simple in assembly structure, and has the advantages of being safe, reliable and stable in descending speed. Besides, full-sealed design is adopted, service life is long, the number of parts is small, the parts can be repeatedly used, and the device is low in production cost, easy to popularize, small in size and convenient to carry.

Description

[0002] As the number of high-rise buildings in the city continues to increase, the height of the floors continues to increase, and the density of high-rise buildings continues to increase. How to safely descend to the ground in critical situations and get out of danger as soon as possible has become an important issue in urban emergency management. However, due to the narrow and poor roads between high-rise buildings, it is often difficult for people trapped in high-rise buildings to rescue themselves, and more professional outside rescue personnel are needed. Using aerial ladders, helicopters and other equipment for rescue, although general The ladder is about 40 meters long and requires a certain amount of space on the ground. Helicopters and other rescue methods cannot reach every corner. Rescue from the outside world requires contact and waiting. When a danger occurs suddenly, time is life, and waiting will cause you to lose your life at any time. , self-rescue is the most important means of escape

[0003] Of course, alarms, small fire extinguishers, and safety exit instructions are generally installed in modern buildings, but there are no lifesaving devices. When the contact surface of the person is affected by factors such as water, oil or air humidity, the sliding friction force will decrease, which will cause the human body to fall too fast, and safety accidents will easily occur; and when a large fire occurs, a small fire extinguisher cannot extinguish the fire. To extinguish, first of all, personnel must quickly and safely escape from the fire scene, because the smoke produced by the fire is interlinked, and there will be a lot of smoke at the safety exit, which is easy to suffocate and die. Therefore, a special suitable for high-rise buildings is developed. It can quickly and safely escape in an emergency, and can maintain a constant descent. The reusable escape device has become an urgent problem to be solved.
