Building or structure with multifunctional rope releasing device

Abstract

Provided is a building or a structure with a multifunctional rope releasing device. The multifunctional rope releasing device is arranged on a roof of the building. The multifunctional rope releasingdevice comprises a power transmission system or a hydraulic transmission system or a pneumatic transmission system, a reel, and a stay rope. A rotating shaft of a motor of the power transmission system or the hydraulic transmission system or the pneumatic transmission system can drive the reel to rotate. A round ring is sleeved on the reel, and the round ring can rotate around the reel. A blockingsurface is arranged on the round ring. A blocking component is arranged on the reel. One end of the stay rope is connected with the round ring. The stay rope extends out from the round ring and is coiled on the reel, and then extends out from the reel and is directly connected with a weight or is connected with a weight after passing through a line groove of a turning pulley. The weight structurecomprises a rubber ball or a fixed pulley or a movable pulley. A cable connected with the motor extends out, and is connected with a power supply on the upper part of the building which is provided with the multifunctional rope releasing device, the cable being connected with the power supply through an electrical control system.

[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
