A rope reducer structure of a high-rise circular escape device

Abstract

The invention discloses a rope speed reducer structure of high-rise circulation escape devices. The rope speed reducer structure comprises ropes used for escaping. The ropes are fixed to rotating shafts of the circulation escape devices. Rope guiding openings are formed in the bottoms of the circulation escape devices, and the ropes are guided out of the rope guiding openings. Spring type or hydraulic type supporting rods are symmetrically arranged on the two sides of each guiding opening, wherein the tails of the spring type supporting rods are hinged to the two sides of the guiding opening. Rubber pads are arranged at the ends of the spring type supporting rods, and the ends of the spring type supporting rods are closely attached to the side walls of the rubber pads. The rubber pads are arranged on the ropes in a sleeving manner, and circular knots are arranged at the tails of the ropes at intervals. According to the rope speed reducer structure, sliding friction occurs through the circular knots and the rubber pads, and therefore the kinetic energy of the ropes is reduced. Meanwhile, by means of the spring type supporting rods, part of kinetic energy of the ropes can be converted into potential energy of the spring type supporting rods to be stored, and therefore the ropes can be effectively decelerated. The rope speed reducer structure is simple, convenient to manufacture and high in practicability.

Description

technical field [0001] The invention relates to the technical field of high-rise escape equipment, in particular to a rope reducer structure of a high-rise circular escape device. Background technique [0002] Today, when the safety awareness is getting stronger and the floors are getting higher and higher, the problem of escape from high-rise buildings has become a problem that is not easy to solve but cannot be ignored. At about 9:17 on November 5, 2010, Chuanying District, Jilin City, Jilin Province A fire broke out in a commercial building, killing 19 people and injuring 24 people who were hospitalized. It is understood that the shopping mall has five floors and a construction area of ​​about 42,000 square meters. We operate bedding, bags and bags on the fifth floor, part of which is a children's playground, and the fire department is located on the first floor. All fires on the first to fourth floors, and partial fires on the fifth floor. There are many floors in high-r...

[0002] Today, when the safety awareness is getting stronger and the floors are getting higher and higher, the problem of escape from high-rise buildings has become a problem that is not easy to solve but cannot be ignored. At about 9:17 on November 5, 2010, Chuanying District, Jilin City, Jilin Province A fire broke out in a commercial building, killing 19 people and injuring 24 people who were hospitalized. It is understood that the shopping mall has five floors and a construction area of ​​about 42,000 square meters. We operate bedding, bags and bags on the fifth floor, part of which is a children's playground, and the fire department is located on the first floor. All fires on the first to fourth floors, and partial fires on the fifth floor. There are many floors in high-rise buildings, and the evacuation distance is long, resulting in a corresponding change in the time spent. It is long, and it is difficult to concentrate and evacuate people, and it is easy to cause heavy casualties; in addition, most cities with high-rise buildings do not have climbing fire trucks. Even if there are, the height is not enough to meet the needs of safe evacuation, and climbing is difficult. If there is no special fire elevator or the fire elevator fails, the firefighters can only walk upstairs to rescue from the stairs. Not only will they "collide" with the evacuated crowd, which will affect the rescue efficiency, but also limited by physical factors. After climbing a certain height on foot, The heart rate and breathing speed up, and the physical strength decreases, which is not conducive to carrying out fire fighting and rescue activities. Most of the existing high-rise escape devices can only be used once, the rescue interval is long, and the rescue efficiency is too low. Safety cannot be effectively guaranteed
