Novel high-rise escape device

Abstract

The invention discloses a novel high-rise escape device which comprises an outer frame, a rope, a center shaft and a braking device. The outer frame is a regular frame formed by welding a metal material. The center shaft is made from a metal material the same as the outer frame, is connected to the geometric center line of the outer frame and can freely rotate through bearing connecting points onthe inner side and the outer side of the outer frame. One end of the rope is fixed to the joint of the center shaft and the outer frame, and evenly wound around the outer surface of the center shaft.The other end of the rope is connected with a safety hook. The braking device is a drum type braking device connected to the center shaft. The rope is an aramid fiber rope, the limit oxygen index (LoiO of the rope is larger than 28, and the extension strength is larger than 300 KN. The side, close to the braking device, of the outer frame is bound and connected with a wearable safety belt. A convenient connecting buckle is arranged on the wearable safety belt.

Description

technical field [0001] The invention belongs to the field of high-rise escape equipment processing, in particular to a novel high-rise escape device. Background technique [0002] The escape device is composed of hooks (or rings), slings, ropes and speed control. It can be installed on building windows, balconies or flat roofs, etc. with special installation equipment, and can also be installed on elevated fire trucks to rescue victims in high-rise building fires. [0003] At present, the capacity of fire emergency rescue equipment in my country is seriously out of balance with the rapid development of high-rise buildings. First, the height-lifting and long-range capabilities of the equipment are far behind the high-level development of high-rise buildings. The existing fire-fighting water tank trucks have only 8-storey sprinkler capacity. The height of the building, the highest lifting capacity of the ladder truck is only about 15 stories. For a fire in a higher high-rise b...

Problems solved by technology

In addition to family fire protection awareness and economic factors, the main reason is that it is difficult to apply to the elderly, young, sick and disabled, and there may be mutual entanglement when multiple households use it at the same time, as well as installation problems and regular maintenance. It is difficult to enter the homes of ordinary people.

More importantly, at this stage, most escape devices can only be used in the design of floors below 100 meters, and there is no corresponding product for floors above 100 meters, and the rope materials in the prior art have the disadvantages of being not fire-resistant and flame-retardant
