Multifunctional rope releasing device

Abstract

The invention discloses a multifunctional rope releasing device. The multifunctional rope releasing device comprises a shell, an air pressure transmission system, coiling blocks or rotating shafts and pull ropes. The air pressure transmission system comprises a pneumatic motor. The pneumatic motor, the coiling blocks or the rotating shafts and the pull ropes are arranged in the shell. The pneumatic motor is connected with the coiling blocks or the rotating shafts through the transmission mechanism and can drive the coiling blocks or the rotating shafts to rotate, the coiling blocks or the rotating shafts are sleeved with circular rings, and the circular rings can rotate around the coiling blocks or the rotating shafts. The circular rings are provided with blocking faces. The coiling blocks or the rotating shafts are provided with blocking pieces. One ends of the pull ropes are connected to the circular rings. After the blocking pieces on the coiling blocks or the rotating shafts clamp the blocking faces on the circular rings, the pull ropes extend out of the circular rings to be wound on the coiling blocks or the rotating shafts to extend out of the coiling blocks or the rotating shafts to be connected with weights.

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...

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. 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 fire-fighting and escape

In a word, 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 rope-releasing equipment. In case of 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
