Building or structure with multifunctional rope releasing device

Abstract

The invention provides a building or structure with a multifunctional rope releasing device. The multifunctional rope releasing device is arranged on the roof of the building and comprises an electrictransmission system or a hydraulic transmission system or a pneumatic transmission system, winding drums or rotating shafts and pull ropes. Rotation shafts of motors of the electric transmission system or the hydraulic transmission system or the pneumatic transmission system can drive the winding drums or the rotating shafts to rotate. Rotation ring bodies are connected to winding drum shafts ofthe winding drums mentioned above or the rotating shafts mentioned above. Each rotation ring body mentioned above can only rotate in one direction and is locked and cannot rotate in the other direction. The pull ropes mentioned above are connected to the rotation ring bodies. The pull ropes mentioned above are wound around the winding drums or the rotating shafts and extend out from the winding drums or the rotating shafts after extending out from the rotation ring bodies. A cable connected with an electric motor extends downwards to the lower portion or the outer portion of the building and is connected with a power supply through a main contact of a contactor. A coil of the contactor mentioned above is connected with a PLC and the power supply to form a loop.

Description

technical field [0001] The application belongs to a building or structure with functions of fire extinguishing, rescue and escape. Background technique [0002] Fires in high-rise buildings or structures have always drawn people's attention. In the event of a fire, the reliability of fire elevators is worth pondering. There is also an arm-raising fire truck used in existing firefighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters. Rescue people, 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 the above-mentioned high-rise buildings or structures catch 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 or structures have incomplete fire-fighting facilities, and the ex...

[0002] Fires in high-rise buildings or structures have always drawn people's attention. In the event of a fire, the reliability of fire elevators is worth pondering. There is also an arm-raising fire truck used in existing firefighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters. Rescue people, 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 the above-mentioned high-rise buildings or structures catch 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 or structures have incomplete fire-fighting facilities, and the existence of fire hydrant doors is blocked by residents. Various phenomena such as blocking with sundries will bring resistance to fire extinguishing and escape.

In short, when the height of the ladder truck is not enough, the fire rescue personnel are fully armed to 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 refuge layer is equipped with 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 there are also complex structures and high costs. It is necessary to study reliable and safe fire extinguishing, rescue and escape measures outside the building
