Building with multifunctional reeling-off equipment

Abstract

The invention relates to a building with multifunctional reeling-off equipment. The building with the multifunctional reeling-off equipment comprises the multifunctional reeling-off equipment which isarranged on a roof, a refuge floor or an upper floor of the building; the multifunctional reeling-off equipment comprises a motor, rotating bodies and a descent control device; a rotating shaft of the motor is connected to the rotating bodies directly or through transmission mechanisms; the rotating bodies are connected with ratchet mechanisms; the descent control device is arranged on a rotatingbody II; descent control ropes of the descent control device extend out of the rotating body II, then are wound around the rotating body II or are wound around winding drums II or a winding shaft IIand extend out of the rotating body II, the winding drums II or the winding shaft II; cables connected to the motor extend downwards to the lower part or the exterior of the building to be connected to a power supply through electrical elements capable of connecting and disconnecting the power supply; and the electric appliance elements can be used for enabling the motor to be connected to the power supply and to rotate forwards or reversely.

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, so 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 inco...

Problems solved by technology

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, so 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-fighting and escape

In short, 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 the rope-releasing equipment. In the event of a 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 measures for fire extinguishing, rescue and escape outside the building
