Multifunctional rope unwinding equipment

Abstract

The invention discloses multifunctional rope unwinding equipment. The multifunctional rope unwinding equipment comprises a shell body, a motor, a reel and a pull rope, wherein the motor, the reel andthe pull rope are arranged in the shell body; the motor is capable of driving the reel to rotate; a circular ring sleeves the reel; the circular ring is capable of rotating around the reel; a stoppingsurface is arranged on the circular ring; a stopping element is arranged on the reel; one end of the pull rope is connected to the circular ring; the pull rope extends out from the circular ring andis wound on the reel, and then extends out from the reel and is connected with a heavy object; a cable connected with the motor is connected with a power supply through a main contact of a contactor;and a coil of the contactor is connected with a PLC and the power supply to form a loop.

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...

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 f
