Emergency life-saving device for firefighting

Abstract

The invention belongs to the technical field of fire-fighting equipment, relating to an emergency life-saving device for firefighting. The emergency life-saving device for firefighting comprises a rope deploying and retracting device, wherein one end of the rope is fixed on an axis in a shell, the other end is introduced out of the shell and tied on a multi-claw hook of a multi-claw throwing gun, the axis is provided with a driving device for manually and electrically driving the axis to rotate and a brake device for the axis, a gear shifter is arranged between the axis and the driving device, the lower end of the shell is connected with a seat basket for being sat by people or a safety rope for being tied, the multi-claw throwing gun can throw the multi-claw hook to 20-200 meters through a projectile or a mechanical ejection device, the lower end of the cylinder of the multi-claw throwing gun is provided with a rope temporary storage cylinder, and part of the rope under the multi-claw hook is sequentially overlapped in the rope temporary storage cylinder. The emergency life-saving device for firefighting has the advantages of simple structure, small size, safety and reliability, easiness and rapidness in climb of high-rise buildings, and being applicable to rescue operation of armed police and firefighters or self-rescuing operation of residents.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to an emergency life-saving device for fire-fighting. Background technique [0002] At present, high-rise buildings are relatively common. When rescues are carried out after sudden disasters such as earthquakes and fires, the first choice is to ask firefighters to go to the rescue. The main equipment of firefighters is fire trucks and aerial ladders. In some places, fire trucks cannot drive in and ladders cannot be erected, which will inevitably make emergency rescue work at a standstill or helpless; or when firefighters cannot arrive in time, and local residents do not have rescue equipment, good rescue time will be lost; In addition, due to the trapped environment, rock climbers and explorers cannot return after reaching a high altitude or a special location, making rescue work difficult. Contents of the invention [0003] The object of the present invention is ...
