Problems solved by technology

[0005] The escape descent device can carry a single person with a weight of about 100 kilograms to slide down freely at a time, and its sliding speed is about 0.5-5 meters per second. Different, slightly different, the existing escape equipment is high in cost, complex in structure, and has certain potential safety hazards. It is necessary to provide a more stable and safe escape equipment

Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] The device includes a rotating shaft 1 and a damping chamber 2. The stirring blade 3 rotates in the damping chamber 2 through the rotating shaft 1. The lifesaving rope is wound on the rotating shaft, and one end is connected to a hook. During the process, the rotating shaft 1 is equipped with a bearing 6, which drives the stirring blade 3 on the rotating shaft 1 to rotate. Due to the buffering effect of the damping fluid and the damping structure in the damping chamber 2, the slow down function of the device during the down process is realized. .

[0019] The damping fluid here is damping grease, also called resistance grease and anti-vibration grease. It is a lubricating grease refined with high-purity inorganic thickener and synthetic oil and various additives. It has a buffering effect and can slow down the vibration of the produc...

Abstract

The invention relates to a descent control device for escaping. The descent control device comprises a rotary shaft, a damping cavity and stirring vanes. The stirring vanes are arranged in the damping cavity and can rotate through the rotary shaft. A life rope is wound on the rotary shaft, the upper end of the rope is connected with a hanging hook, the lower end of the whole device is connected with a user or an object, damping liquid fills in the damping cavity, and a damping structure is further disposed inside the damping cavity. By means of the descent control device for escaping, the user or the object can descend more stably and smoothly while slowly descending, and the descent control device is safer to use.

Description

technical field [0001] The invention belongs to the field of lifesaving devices and relates to an escape descent device. Background technique [0002] High-rise accidents occur frequently, and fires, gas leaks, etc. all seriously threaten people's lives. However, there is a serious imbalance between my country's fire emergency rescue equipment capabilities and the rapid development of high-rise buildings. [0003] One is that the height-lifting and long-range shooting capabilities of the equipment are far behind the height development of high-rise buildings. The existing fire-fighting water tank trucks have limited water-spray fire-extinguishing capabilities and aerial ladder trucks; the other is that the equipment is bulky and has poor mobility. Impact on road traffic and surrounding environment of buildings. [0004] With the continuous acceleration of industrialization and urbanization in our country, the above-mentioned contradictions will become increasingly prominent...
