Multifunctional reel-off equipment

Abstract

Provided is multifunctional reel-off equipment. The multifunctional reel-off equipment comprises a shell, motors, winding drums and descent control devices. The motors, the winding drums and the descent control devices are arranged in the shell, the motors are connected with the winding drums and can drive the winding drums to rotate, the descent control devices are arranged on the winding drums or outside the winding drums and located in the shell, slow descent ropes extending from the descent control devices are wound on the winding drums, and the slow descent ropes extend from the winding drums and are connected with weights. The multifunctional reel-off equipment is connected with a length of a control cable which extends to the outside of the shell and is connected with a controller or is connected with a length of a control pull rope which extends to the outside of the shell and is connected with a touch switch.

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] The world's second tallest tower, the 540-meter-high Ostankino TV Tower in Russia, suffered a fire, which caused all major Russian TV stations to stop broadcasting. Communications between all paging stations in Moscow, the Ministry of Internal Affairs, and the Moscow emergency system were interrupted. Four people were trapped in the elevator. Death, many people were injured, the structure of the TV tower was severely damaged, shocking the world, and the fire of high-rise buildings has always attracted people's attention, but the reliability of fire elevators in the event of a fire is more worthy of consideration. 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 ...

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
