Building with multifunctional rope unwinding device

Abstract

The invention provides a building with a multifunctional rope unwinding device. The building with the multifunctional rope unwinding device comprises the multifunctional rope unwinding device arrangedabove the building; the multifunctional rope unwinding device comprises an electric machine, rotating bodies and pulling ropes; the electric machine is connected with the rotating bodies and can drive the rotating bodies to rotate in a singular direction; the rotating bodies are connected with ratchet mechanisms; the pulling ropes are connected to the rotating bodies; the pulling ropes are woundon the rotating bodies or wound on coiling blocks or rotating shafts after extending out of the rotating bodies, and the pulling ropes extend out of the rotating bodies or the coiling blocks or the rotating shafts to be directly connected with heavy objects or are connected with the heavy objects after penetrating wire grooves of direction changing pulleys; and a cable connected with the electricmachine outwards extends to be connected with a power source through a main contact point of a contactor above the building with the multifunctional rope unwinding device.

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
