Building with multifunctional rope paying-off device

Abstract

A building with a multifunctional rope paying-off device comprises the multifunctional rope paying-off device arranged on the upper side of the building. The multifunctional rope paying-off device comprises a motor, rotating bodies and stay ropes. A rotating shaft of the motor is directly connected with the rotating bodies or through transmission mechanisms. The rotating bodies are connected withratchet mechanisms. The stay ropes are connected to the rotating bodies. Each stay rope extend outs from the corresponding rotating body and then is wound around the corresponding rotating body or a corresponding winding drum and extend outs from the corresponding rotating body or corresponding winding drum. A cable connected with the motor extends outwards and is connected, on the upper side of the building with the multifunctional rope paying-off device, with a power source through main contacts of a contactor. A coil of the contactor, a PLC and the power source are connected and constitutea loop.

Description

technical field [0001] The application belongs to a building with functions of fire extinguishing, rescue and escape. 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. Various phenomena bring resista...
