Multifunctional rope releasing equipment

Abstract

The invention discloses multifunctional rope releasing equipment. The multifunctional rope releasing equipment comprises a shell, a motor, a winding drum, and a descent control device; the motor can drive the winding drum to rotate; the winding drum is sleeved with a ring, and the ring can rotate around the winding drum; a stop surface is arranged on the ring; a stop piece is arranged on the winding drum; the ring is provided with the descent control device; a slow descending rope of the descent control device is wound on the winding drum to connect with a weight after extending from the descent control device; a cable connected with the motor is connected with a power supply through a main contact point of a contactor; a coil of the contactor is connected with a PLC and the power supply to form a loop; and a button or a touch screen connected with the PLC can be used for controlling closing of the main contact point of the contactor and electrifying the motor to forwards or reverselyrotate.

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...

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, 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 t...
