Multifunctional rope unreeling device

Abstract

The invention discloses a multifunctional rope unreeling device. The multifunctional rope unreeling device comprises a shell, a pneumatic transmission system, rollers or rotating shafts, a descent control device and pull ropes. The pneumatic transmission system comprises a pneumatic motor. The pneumatic motor, the rollers or rotating shafts, the descent control device and the pull ropes are arranged in the shell. The pneumatic motor can drive the rollers or rotating shafts to rotate. The rollers or rotating shafts are sleeved with one or more circular rings, wherein the circular rings can rotate around the rollers or rotating shafts. The circular rings are provided with blocking faces, and the rollers or rotating shafts are provided with blocking pieces. At least one circular ring is connected with one end of the corresponding pull rope, and at least one circular ring is provided with the descent control device. The corresponding pull rope extends out from the corresponding circular ring, is wound on the corresponding roller or rotating shaft and then extends out from the corresponding roller or rotating shaft to be connected with a weight. A descent control rope extending out from the descent control device is wound on the corresponding roller or rotating shaft and then extends out from the corresponding roller or rotating shaft to be connected with the weight.

Description

technical field [0001] The application belongs to an outdoor fire extinguishing, rescue and escape equipment used in the construction field. Background technique [0002] Fires in high-rise buildings have always been drawing people's attention, and the reliability of fire elevators during fires is worth pondering. There are also existing fire-fighting and life-saving arms-raising fire trucks, which can generally carry out fire fighting and rescue at a height of 53 meters, and there is a limit to the height of the fire-fighting ladder truck. Usually, the fire-fighting ladder truck can only rise to the limit value of 80 % or so, if the ground wind reaches 4 to 5, the fire ladder truck cannot be elevated for operation. In this way, once a high-rise building above 50 meters is on fire or people are trapped, the fire ladder will be difficult to play. In general, trapped people can only Relying on their own ability to escape, and some high-rise buildings have incomplete fire prot...

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. 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
