Description
Technical Field
The invention relates to a rope reversing disc, and belongs to the field of escape equipment.
Background
Tall buildings, i.e. high-rise buildings, residential buildings over 10 floors and other civil buildings over 24 meters high are called tall buildings. A fire refers to a disaster caused by uncontrolled combustion in time and space. High-rise fires have become one of the major disasters threatening the safety of urban public and social development.
High-rise fire has the characteristics of rapid spread of fire, difficult evacuation and great difficulty in fighting, and once fire catches, the high-rise fire is difficult to control and escape due to complex structure and dense personnel. Countless high-rise fire cases show that the existing high-rise fire rescue means cannot adapt to the construction and development of high-rise buildings. In an urgent situation, helpless trapped people often choose to jump stairs from dense smoke and risk for survival by using a single twisted rope, and most of the trapped people fall to the ground at high altitude to be injured and killed.
The existing device which can slide down along a rope is a descent control device, but the descent control device usually winds the rope on the descent control device, and then counteracts a part of the body weight through the friction force between the descent control device and the rope, so as to achieve the purpose of safe descent control. However, the descent control device can cause abrasion to the rope, influence the strength of the rope and cause potential safety hazards; meanwhile, the self-weight of the human body is different, but the resistance of the descent control device is constant, so that the descent control device cannot adapt to a plurality of people or people with heavy weight.
