Multifunctional rope paying-off device

Abstract

A multifunctional rope paying-off device comprises a shell, a motor, winding drums, a descent control device and stay ropes. A rotating shaft of the motor is directly connected with the winding drumsor through transmission mechanisms and can drive the winding drums to rotate. Each winding drum is sleeved with one or more round rings. The round rings are provided with stopping faces. The winding drums or rotating shafts are provided with stopping pieces. At least one round ring is connected with one end of the corresponding stay rope. At least one round ring is provided with the descent control device. Each stay rope extends out from the round ring, is wound around the corresponding winding drum and then extends out from the winding drum to be connected with a weight. Each slow descent rope extending out from the descent control device is wound around the corresponding winding drum and then extends out from the corresponding winding drum to be connected with a weight II. 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
