Building provided with multifunctional rope unreeling equipment

Abstract

The invention relates to a building provided with multifunctional rope unreeling equipment. The building provided with the multifunctional rope unreeling equipment comprises the multifunctional rope unreeling equipment arranged above the building, and the multifunctional rope unreeling equipment comprises a motor, rotary bodies and a descent control device, wherein the motor is connected to the rotary bodies directly or through transmission components; the rotary bodies are connected with a ratchet mechanism; the descent control device is arranged on one rotary body; a slow descent rope of thedescent control device extends out from the rotary body and then is wound on the rotary body or is wound on a reel or a rotary shaft, and extends out of the rotary body, the reel or the rotary shaftto be connected with a weight directly or penetrates through a rope groove of a deflection pulley to be connected with the weight; a cable connected with the motor extends outwards and is connected with a power source through a main contact of a contactor above the building provided with the multifunctional rope unreeling equipment; and the coil of the contactor is connected with a PLC and the power source to form a 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, and the reliability of fire elevators in the event of a fire is worth pondering. There is also the arm-raising fire truck used in the existing fire-fighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, and the climbing of the fire-fighting ladder truck has a limit. Usually, the fire-fighting ladder truck can only rise to 80 of the limit value. % or so, if the wind force on the ground reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to raise the operation. In this way, once a high-rise building above 50 meters catches fire or people are trapped, it will be difficult for the fire-fighting aerial ladder to play a role. Rely on one's own ability to escape, but some high-rise buildings...

In this way, once a high-rise building above 50 meters catches fire or people are trapped, it will be difficult for the fire-fighting aerial ladder to play a role. Rely on one's own ability to escape, but some high-rise buildings have incomplete fire-fighting facilities, fire hydrant doors are blocked by residents with sundries and other phenomena, which bring resistance to fire-fi
