Escapement-type escape device for high-rise buildings

Abstract

The invention relates to an escapement-type escape device for high-rise buildings, comprising an escapement and a vibration system, wherein the escapement comprises a ratchet wheel and a pawl; a principal shaft penetrates through the central hole of the ratchet wheel; the pawl is connected with two sides of the ratchet wheel by a hinge pin; the vibration system comprises a flywheel, a torsional spring and a driving plate; the flywheel is in power link with the ratchet wheel by the pawl; the torsional spring winds at the central shafts of the flywheel and the driving plate; the driving plate is in power link with the principal shaft by the pawl; a rope is nested in a rope groove of the principal shaft; and a pressing wheel is fixed outside of the ratchet wheel by a pressing wheel frame. Stopping and moving movement with fixed descending period of people is realized by the escapement vibration system with constant period and continuous vibration and ultimately the highest descending speed of people is controlled. The escape device has the advantages of small volume, low manufacturing cost and low manufacturing technology difficulty and the characteristics of controllable slow descending speed, reciprocating motion, convenience for installation and the like.

Description

technical field [0001] The invention belongs to the technical field of escape devices, and relates to an escapement-type high-rise escape device that uses a constant-period, continuous-vibration escapement vibration system to realize a fixed-period stop motion for people falling, and finally realizes the maximum speed control for people falling . Background technique [0002] As the saying goes: "Water and fire have no mercy"; "A thief steals half, but fire burns everything". Today, fire is a common catastrophic problem faced by people all over the world. According to the information provided by the United Nations "World Fire Statistics Center", the loss of fires in the United States doubles in less than 7 years, Japan doubles in 16 years on average, and China doubles in 12 years on average. There are more than 10,000 fires every day in the world, causing hundreds of deaths. In recent years, the average annual fire loss in my country is nearly 20 billion yuan, and more th...

But its huge body and heavy quality also greatly restrict its playing field!

[0006] We went to the Zhenjiang Fire Station to investigate and found out that the self-rescue ability and awareness of citizens are generally not high at present, and there are not many corresponding drills. We really need to strengthen publicity and education in this regard! During the interview with the squadron instructor, we learned that the main cause of casualties caused by the fire is the toxic gas produced by the combustion, the suffocation caused by too thick smoke, and the improper measures taken after being trapped
