Multifunctional reeling-off equipment

Abstract

The invention discloses multifunctional reeling-off equipment. The multifunctional reeling-off equipment comprises a motor, rotating bodies, pulling ropes and a descent control device; the motor is connected to the rotating bodies through transmission mechanisms; the rotating bodies are connected with ratchet mechanisms; the pull ropes are connected to a rotating body I; the descent control deviceis arranged on a rotating body II; the pull ropes and descent control ropes of the descent control device extend out of the rotating bodies, then are wound around the rotating bodies or are wound around winding drums or winding shafts and extend out of the rotating bodies, the winding drums or the winding shafts; cables connected to the motor are connected to a power supply through main contactsof contactors; and coils of the contactors are connected to a PLC and the power supply to form a loop.

Description

technical field [0001] The application belongs to an outdoor fire extinguishing, rescue and escape equipment used in the construction field. Background technique [0002] Fires in high-rise buildings have always been drawing people's attention, and the reliability of fire elevators during fires is worth pondering. There are also existing fire-fighting and life-saving arms-raising fire trucks, which can generally carry out fire fighting and rescue at a height of 53 meters, and there is a limit to the height of the fire-fighting ladder truck. Usually, the fire-fighting ladder truck can only rise to the limit value of 80 % or so, if the ground wind reaches 4 to 5, the fire ladder truck cannot be elevated for operation. In this way, once a high-rise building above 50 meters is on fire or people are trapped, the fire ladder will be difficult to play. In general, trapped people can only Relying on their own ability to escape, and some high-rise buildings have incomplete fire prot...

AI Technical Summary

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. In this way, 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 a word, 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 rope-releasing equipment. In case of 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
