Building with multifunctional reeling-off device

Abstract

The invention discloses a building with a multifunctional reeling-off device. The multifunctional reeling-off device comprises an electric motor, a rotating body and a pull rope; a rotating shaft of the electric motor is directly connected with the rotating body or connected with the rotating body through a transmission component, the rotating body is connected with a ratchet mechanism, the pull rope is connected to the rotating body, the pull rope extends from the rotating body and then is wound on the rotating body or wound on a winding drum or rotary shaft and extends out of the rotating body or winding drum or rotary shaft to be directly connected with a weight or penetrates a line groove of a direction changing pulley to be connected with the weight, and a cable connected with the electric motor is arranged above the building with the multifunctional reeling-off device and is connected with a power source through an electrical control system.

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...

[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 rescue, 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 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 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
