Multifunctional rope releasing device

Abstract

The invention discloses a multifunctional rope releasing device. The device 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. Winding drum shafts of the winding drums or the rotating shafts are connected with one or more rotating ring bodies. The above rotating ring bodies can only rotate in one direction and are locked and cannot rotate in the other direction. The decent control device and the pull ropes are arranged on the rotating ring bodies. Descent control ropes extending out from the above descent control device are wound around the winding drums or the rotating shafts and extend out from the winding drums or the rotating shafts. The above pull ropes extend out from the rotating ring bodies, are wound around the winding drums or the rotating shafts and extend out from the winding drums or the rotating shafts. A remote controller is used or the controlling pull ropes are used for controlling a rotating shaft of the motor to rotate, and the descent control ropes and the pull ropes rotationally extend out from the winding drums or the rotating shafts, the rotationally extending-out descent control ropes are pulled on the descent control device in a hanging manner, and the rotationally extending-out pull ropes are pulled on the rotating ring bodies in a hanging manner.

Description

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

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 f
