Multifunctional unwinding equipment

Abstract

The invention discloses multifunctional unwinding equipment. The multifunctional unwinding equipment comprises motors, rotating bodies and pulling ropes; a rotating shaft of each motor is connected with the corresponding rotating body directly or through a transmission mechanism; each rotating body is connected with a ratchet wheel mechanism; the pulling ropes are connected with each rotating body; the pulling ropes wind the rotating bodies or wind winding drums and extend out from the rotating bodies or the winding drums to directly connect a heavy object or connect the heavy object after penetrating through a wire groove of a direction-changing pulley after extending out from the rotating bodies; the structure of the heavy body comprises a fixed pulley or a movable pulley which adopts arubber ball; and cables which are connected with the motors extend outwards and are connected with a power supply through electrical apparatus elements which can be switched on or switched off.

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. 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 insufficient fire-fighting facilities, and the fire hydrant doors are blocked by residents with debris, etc. Vario...

[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 insufficient fire-fighting facilities, and the fire hydrant doors are blocked by residents with debris, 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 fire extinguishing, rescue and escape equipment outside the building
