Multifunctional rope releasing device

Abstract

Provided is a multifunctional rope releasing device. The multifunctional rope releasing device comprises a power transmission system or a hydraulic transmission system or a pneumatic transmission system, a reel or a rotating shaft, and a descent control device. A rotating shaft of a motor of the power transmission system or the hydraulic transmission system or the pneumatic transmission system candrive the reel or the rotating shaft to rotate through a transmission mechanism. The motor is an electric motor or a hydraulic motor or a pneumatic motor. The power transmission system comprises theelectric motor. A round ring is sleeved on the reel or the rotating shaft. The round ring can rotate around the reel or the rotating shaft. The round ring is provided with a blocking surface. The reelor the rotating shaft is provided with a blocking piece. The descent control device is arranged on the round ring. A slow descent rope of the descent control device extends out from the descent control device and is coiled on the reel or the rotating shaft, and a cable connected with the electric motor or a motor or a magnetic exchange valve is connected with a power supply through an electricalcontrol 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...

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
