Building with multifunctional rope unwinding device

Abstract

The invention discloses a building with a multifunctional rope unwinding device. The building with the multifunctional rope unwinding device comprises the multifunctional rope unwinding device arranged on a roof layer of the building or an upper storey; the multifunctional rope unwinding device comprises an electric machine, rotating bodies, pulling ropes and a slow descending device; the electricmachine is connected with the rotating bodies which are connected with ratchet mechanisms; the pulling ropes are connected to the rotating bodies; the slow descending device is arranged on the corresponding rotating body; the pulling ropes and slow descending ropes of the slow descending device are wound on the rotating bodies or are wound on coiling blocks after extending out of the rotating bodies, and extend out of the rotating bodies or the coiling blocks to be directly connected with heavy objects or connected with the heavy objects after penetrating wire grooves of direction changing pulleys; and a cable connected with the electric machine downwards extends to the position below the building or the exterior of the building to be connected with a power source through an electric appliance element capable of connecting or disconnecting the power source.

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, and the reliability of fire elevators in the event of a fire is worth pondering. There is also the arm-raising fire truck used in the existing fire-fighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, and the climbing of the fire-fighting ladder truck has a limit. Usually, the fire-fighting ladder truck can only rise to 80 of the limit value. % or so, if the wind force on the ground reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to raise the operation, so once a high-rise building above 50 meters catches fire or people are trapped, it will be difficult for the fire-fighting aerial ladder to play a role. Rely on one's own ability to escape, but some high-rise buildings have inco...

Problems solved by technology

There is also the arm-raising fire truck used in the existing fire-fighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, and the climbing of the fire-fighting ladder truck has a limit. Usually, the fire-fighting ladder truck can only rise to 80 of the limit value. % or so, if the wind force on the ground reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to raise the operation, so once a high-rise building above 50 meters catches fire or people are trapped, it will be difficult for the fire-fighting aerial ladder to play a role. Rely on one's own ability to escape, but some high-rise buildings have incomplete fire-fighting facilities, fire hydrant doors are blocked by residents with sundries and other phenomena, which bring resistance to fire-fighting 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
