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 or a rotating shaft, and a pull rope; the motor, the winding drum or the rotating shaft and the pull rope are arranged in the shell; the motor is connected with the winding drum or the rotating shaft through a transmission mechanism, and can drive the winding drum or the rotating shaft to rotate; the winding drum or the rotating shaft is sleeved with a ring, and the ring can rotate around the winding drum or the rotating shaft; a stop surfaceis arranged on the ring; a stop piece is arranged on the winding drum or the rotating shaft; one end of the pull rope is connected to the ring; the pull rope extends from the ring to wind on the winding drum or the rotating shaft, and then, extends from the winding drum or the rotating shaft; a cable connected with the motor downwards extends, and is connected with a power supply through an electric appliance element capable of connecting with or disconnecting from the power supply; and the electric appliance element can be used for enabling the motor to connect with the power supply and to forwards or reversely rotate.

Description

technical field [0001] The application belongs to a kind of outdoor fire extinguishing, rescue and escape equipment used in the field of buildings. 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, so 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...

AI Technical Summary

Problems solved by technology

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, so 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 fire-fighting and escape

In short, when the height of the ladder truck is not enough, the fire rescue personnel are fully armed and go up the fire floor from the stairs to carry out fire fighting and rescue, which seriously affects the speed and efficiency of rescue and fire fighting. The existing technology has appeared on the roof layer or refuge floor of the building. Set up the rope-releasing equipment. In the event of a fire, the above-mentioned rope-releasing equipment can be controlled to lower the slow-down rope and pull rope for emergency escape. However, the technical solution of the rope-releasing technique has certain safety risks, and also has the disadvantages of relatively complex structure and high cost. It has become necessary to study reliable and safe fire extinguishing, rescue and escape equipment outside the building
