Building with multi-functional rope releasing device

Abstract

The invention discloses a building with a multi-functional rope releasing device. The building with the multi-functional rope releasing device comprises the multi-functional rope releasing device arranged on a roof layer of the building, and the multi-functional rope releasing device comprises a motor, rollers or rotating shafts, descent control devices and pulling ropes; the motor can drive the rollers or the rotating shafts to rotate; one or more rotating ring bodies are connected on roller shafts of the rollers or the rotating shafts; the rotating ring bodies can only rotate in one direction and are locked and cannot rotate in the other direction; the descent control devices and the pulling ropes are arranged on the rotating ring bodies; descent control ropes extending from the descent control devices are wound on the rollers or the rotating shafts; the pulling ropes extend from the rotating ring bodies and are wound on the rollers or the rotating shafts; the descent control ropes and the pulling ropes on the rollers or the rotating shafts can fall and extend to positions under the building for utilization along with rotation of the rollers or the rotating shafts; the falling and extending descent control ropes are hung on the descent control devices; and the falling and extending pulling ropes are hung on the rotating ring bodies.

Description

technical field [0001] The application belongs to a building with functions of fire extinguishing, rescue and escape. 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, but some high-rise buildings...

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 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 measures for fire extinguishing, rescue and escape outside the building
