Multifunctional reeling-off equipment

Abstract

The invention discloses multifunctional reeling-off equipment. The multifunctional reeling-off equipment comprises a motor, winding drums or rotating shafts, a descent control device and pull ropes; the motor can drive the winding drums or the rotating shafts to rotate; one or more rotating ring bodies are connected to winding drum shafts of the winding drums or the rotating shafts; the rotating ring bodies can only rotate in one direction, are locked in the other direction and cannot rotate in the other direction; the descent control device and the pull ropes are arranged on the rotary ring bodies; descent control ropes extending out of the descent control device are wound around winding drums II or a rotating shaft II and extend out of the winding drums II or the rotating shaft II; the pulling ropes extend out of a rotating ring body I, then are wound around winding drums I or a rotating shaft I and extend out of the winding drums I or the rotating shaft I; electric appliance elements can be used for enabling the motor to be connected to a power supply and to rotate forwards or reversely; the motor can rotate forwards or reversely to drive the descent control ropes to extend outof the winding drums II or the rotating shaft II in a rotating mode and to be hung on the descent control device.

Description

technical field [0001] The application belongs to a kind of outdoor fire extinguishing, rescue and escape equipment used in the field of buildings. 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...

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 fire extinguishing, rescue and escape equipment outside the building
