Multi-functional reel-off equipment

Abstract

Disclosed is multi-functional reel-off equipment. The multi-functional reel-off equipment comprises a power transmission system or a hydraulic transmission system or a pneumatic transmission system, rotators and a descent control device, wherein a rotary shaft of a motor of the power transmission system or the hydraulic transmission system or the pneumatic transmission system is connected with the rotators; a ratchet mechanism is arranged on the rotary shaft or the transmission mechanism or the rotators; the rotators can freely rotate only in one direction and cannot freely rotate when locked in the opposite direction; rope baffles are disposed on the rotators or rotating shafts of the rotators; the rope baffles are provided with holes; the descent control device is disposed on one of the rotators; a descent control rope of the descent control device extends out of the descent control device and then penetrates through the holes to be wound on the rotators or winding drums or reels. The multi-functional reel-off equipment is connected with a remote control unit or connected with a section of a control cable provided with a controller or connected with a section of control pulling ropes.

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-climbing fire truck used in the existing firefighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, and the climbing of the fire ladder truck is limited. Usually, the fire 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.

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
