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 above the building; the multifunctional rope unwinding device comprises an electric machine, coiling blocks, a slow descending device and pulling ropes; the electric machine is connected with one ormore coiling blocks and can drive the coiling blocks to rotate; one or more rotating ring bodies are connected to coiling block shafts of the coiling blocks; the rotating ring bodies can only rotatein one direction, and are locked in the other direction and cannot rotate; the slow descending device and the pulling ropes are both arranged on the rotating ring bodies; slowing descending ropes extending of out of the slow descending device are wound on the coiling blocks and extend out of the coiling blocks; the pulling ropes extend out of the rotating ring bodies to be wound on the coiling blocks, and extend out of the coiling blocks; a cable connected with the electric machine downwards can be connected with a power source through an electric appliance element capable of connecting or disconnecting the power source 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, 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
