Multifunctional rope reeling-off equipment

Abstract

The invention discloses multifunctional rope reeling-off equipment which comprises a shell, a motor, a coiling block or rotating shaft and a descent control device. The motor, the coiling block or rotating shaft and the descent control device are arranged in the shell. The motor can drive the coiling block or rotating shaft to rotate through a transmission mechanism. The coiling block or rotatingshaft is sleeved with a circular ring, the circular ring is provided with a blocking face, the coiling block or rotating shaft is provided with a blocking piece, the descent control device is arrangedon the circular ring, a descent control rope of the descent control device is extended out of the descent control device to be coiled to the coiling block or rotating shaft and then extended out of the coiling block or rotating shaft, and a cable connected with the motor is connected with a power source through an electrical control system.

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
