Building or structure with multifunctional unwinding device

Abstract

The invention provides a building or structure with a multifunctional unwinding device. The multifunctional unwinding device is arranged on a roof of the building, and the multifunctional unwinding device comprises an power transmission system or a hydraulic transmission system or a pneumatic transmission system, a winding drum or a rotary shaft and a pull rope; a rotating shaft of a motor of thepower transmission system or the hydraulic transmission system or the pneumatic transmission system can drive the winding drum or the rotary shaft to rotate; a winding drum shaft of the winding drum or the rotary shaft is connected with a rotating ring body, and the rotating ring body can only rotate towards one direction and cannot rotate towards the other direction caused by lock; the pull ropeis connected to the rotating ring body, and after extending out of the rotating ring body, the pull rope is wound on the winding drum or the rotary shaft and extends out of the winding drum or the rotary shaft; and the clockwise rotation or the anticlockwise rotation of the motor drives the pull rope to rotate to extend out of the winding drum or the rotary shaft and be hung on the rotating ring body.

Description

Technical field [0001] This application belongs to a building or structure with fire fighting, rescue, and escape functions. Background technique [0002] Fires in high-rise buildings or structures have always been drawing people’s attention. The reliability of fire elevators in the event of a fire is worth thinking about. There are also existing fire-fighting trucks used for firefighting and rescue, which can generally implement 53-meter-high fire fighting and rescue operations. There is a limit to the height of the fire-fighting ladder truck. Usually, the fire-fighting ladder truck can only rise to about 80% of the limit value. If the ground wind reaches level 4 to 5, the fire-fighting ladder truck cannot raise operations, so 50 meters Once the above-mentioned high-rise buildings or structures catch fire or someone is trapped, the fire-fighting ladder is difficult to function. Generally, the trapped people can only escape by their own ability, and some high-rise buildings or st...

[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
