Building with multifunctional rope unreeling device

Abstract

The invention provides a building with a multifunctional rope unreeling device. The building with the multifunctional rope unreeling device comprises the multifunctional rope unreeling device arranged on a roof layer of the building. The multifunctional rope unreeling device comprises one or more reeling barrels, an object falling mechanical system, pull ropes and a cantilever. The reeling barrels or rotary components connected with the reeling barrels are provided with magnets I. The positions, opposite to the magnets I on the reeling barrels or the rotary components, of non-rotary components are provided with magnets II or metal II or alloy II attracting the magnets I. The pull ropes and the reeling barrels are connected. After being connected with the reeling barrels, the pull ropes extend out of the reeling barrels to penetrate through direction change pulleys on the cantilever and then are connected with heavy objects.

Description

technical field [0001] The application belongs to a building with functions of fire extinguishing, rescue and escape. 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 of the fire-fighting ladder tr...

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 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. Do free fall motion everywhere, so that the descending speed of the ropes of the existing equipment cannot be controlled, so the existing rope-releasing equipment has risks in the process of releasing the ropes, especially for high-rise or super high-rise buildings. Risk, it may cause the rope to hit the glass of the outer wall or be entangled and cannot be used, especially the whiptail effect will be produced after the free fall below the building, so that the end of the rope is bounced and hit or entangled together and cannot be used. This kind of risk will increase with the rise of building height, and the existing rope-laying equipment still has the disadvantages of relatively complex structure and high cost. It has become a reality to study buildings with reliable and safe functions of fire extinguishing, rescue and escape outside the building. necessary
