Device for driving ropes in tall building circulating escape device

Abstract

The invention discloses a device for driving ropes in a tall building circulating escape device. The device is characterized in that rope rotating shafts are fixed inside the circulating escape device; ropes for escape are fixed to the rope rotating shafts of the circulating escape device; mounting grooves are formed in the circulating escape device right below the rope rotating shafts; spring type supporting pieces I are mounted in the mounting grooves and are fixed; the tops of the spring type supporting pieces I are fixed on the bottom sides of the rope rotating shafts; the rope rotating shafts are connected with a driving motor through speed reducers; rope guide openings are formed in the bottom of the circulating escape device; the ropes are guided out of the rope guide openings; spring type or hydraulic type support rods are symmetrically arranged on the two sides of each guide opening; the tail parts of the spring type support rods are hinged to the two sides of each guide opening respectively; rubber blankets are arranged at the end parts of the spring type support rods; the end parts of the spring type support rods tightly fit the side walls of the rubber blankets; the rubber blankets sleeve the ropes; and circular knots are arranged at the tail parts of the ropes at interval. The device is simple in structure, 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 device for driving a rope in 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 hig...

[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
