Building or structure with multifunctional rope unwinding equipment

Abstract

The invention discloses a building or a structure with multifunctional rope unwinding equipment. The multifunctional rope unwinding equipment is arranged on a roof of the building and comprises an electric transmission system or a hydraulic transmission system or a pneumatic transmission system, a rotating body and a pull rope, a rotating shaft of a motor of the electric transmission system or thehydraulic transmission system or the pneumatic transmission system is connected to the rotating body, the rotating body is connected to a ratchet wheel mechanism, the pull rope is connected to the rotating body, the pull rope extends out of the rotating body to wind around the rotating body or wind around a winding drum and then extends out of the rotating body or the winding drum to be connectedto a heavy object, a cable connected to the motor extends downwards to the lower part or the exterior of the building to be connected to a power supply through a main contact of a contactor, and a coil of the contactor is connected to a PLC and the power supply to form a loop.

Description

technical field [0001] The application belongs to a building or structure with functions of fire extinguishing, rescue and escape. Background technique [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 ex...

[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
