Multifunctional rope release equipment

Abstract

The invention provides multifunctional rope release equipment. The multifunctional rope release equipment comprises power transmission systems or hydraulic transmission systems or air pressure transmission systems, rotary bodies and pull ropes. Rotary shafts of motors of the power transmission systems or the hydraulic transmission systems or the air pressure transmission systems are directly connected with the rotary bodies or connected with the rotary bodies through transmission mechanisms. Ratchet mechanisms are arranged on the rotary shafts or the transmission mechanisms or the rotary bodies. The rotary bodies can rotate freely only in one direction. The rotary bodies or the rotary shafts of the rotary bodies are provided with rope blocking plates. Holes are formed in the rope blocking plates. The pull ropes are fixedly connected to the rotary bodies and wound around the rotary bodies in multiple cycles, penetrate the holes and then are wound around the rotary bodies or reels or scrolls. The multifunctional rope release equipment is connected with a remote control unit or the multifunctional rope release equipment is connected with a segment of control cable with a controller or the multifunctional rope release equipment is connected with a segment of control pull rope.

Description

technical field [0001] The application belongs to a kind of outdoor fire extinguishing, rescue and escape equipment used in the construction field. Background technique [0002] Fires in high-rise buildings have always attracted people's attention. In the event of a fire, the reliability of fire elevators is worth pondering. There are also existing fire trucks used for fire and lifesaving, which can generally implement fire fighting and rescue people at a height of 53 meters. , and there is a limit to the height of the fire-fighting aerial ladder truck. Usually, the fire-fighting aerial ladder truck can only rise to about 80% of the limit value. Once a high-rise building catches fire or people are trapped, it is difficult for the fire ladder to play a role. Generally, the trapped people can only rely on their own ability to escape, but some high-rise buildings have incomplete fire-fighting facilities, and the fire hydrant doors are blocked by residents with sundries, etc. V...

[0002] Fires in high-rise buildings have always attracted people's attention. In the event of a fire, the reliability of fire elevators is worth pondering. There are also existing fire trucks used for fire and rescue, which can generally implement fire fighting and rescue people at a height of 53 meters. , and there is a limit to the height of the fire-fighting aerial ladder truck. Usually, the fire-fighting aerial ladder truck can only rise to about 80% of the limit value. Once a high-rise building catches fire or people are trapped, it is difficult for the fire ladder to play a role. Generally, the trapped people can only rely on their own ability to escape, but some high-rise buildings have incomplete fire-fighting facilities, and the fire hydrant doors are blocked by residents with sundries, etc. Various phenomena bring resistance to fire extinguishing and escape

In a word, when the height of the ladder truck is not enough, the fire rescue personnel are fully armed and go up the fire floor from the stairs to carry out fire fighting and rescue, which seriously affects the speed and efficiency of rescue and fire fighting. The existing technology has appeared on the roof layer or refuge floor of the building. Set up rope-releasing equipment. In case of fire, the above-mentioned rope-releasing equipment can be controlled to lower the slow-down rope and pull rope for emergency escape. However, the technical solution of the rope-releasing technique has certain safety risks, and also has the disadvantages of relatively complex structure and high cost. It has become necessary to study reliable and safe fire extinguishing, rescue and escape equipment outside the building
