Problems solved by technology

There is also an arm-raising fire truck used for existing fire rescue and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, which is approximately equivalent to a height of 15 floors. Most of the time, fire officers and soldiers can only look at the "fire" and sigh, let alone go upstairs to save people
There is a limit to the height of the fire-fighting aerial ladder truck. Usually, the fire-fighting aerial ladder truck can only rise to about 80% of the limit value. If the ground wind reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to rise to work
Once a high-rise building above 50 meters catches fire or people are trapped, it is difficult for the fire ladder to play a role. Generally, the trapped people can only rely on their own ability to escape, and the fire-fighting facilities of some high-rise buildings are incomplete, and the fire hydrant door is used by residents. Various phenomena such as sundries blockage will bring resistance to fire fighting and escaping
In short, in the traditional high-rise escape, elevators are prohibited and dangerous, and there is a danger of being blocked by fire and thick smoke when taking the stairs
In addition, there are unsafe and unstable problems in the various descending devices and escape devices currently available for self-rescue escape. Within a few seconds of jumping down, the human body starts from free fall, that is to say, the downward acceleration of the human body at the moment of jumping down is g (9.8 m / s 2 ), and then the falling speed of the human body rapidly accelerates from rest When the effect reaches 1.5 meters per second, the descending device will fully play its role to maintain the descending speed of the human body at 1.5 meters per second. The feeling of weightlessness in the short period of time when the human body falls from rest to a constant speed will cause the user Therefore, there are still many problems in the widespread promotion of descending devices, including the quality of descending devices, the safety of descending devices, the storage of descending devices, the maintenance of descending devices, The hook of the descending device affects the aesthetics of the interior, the installation and use of the descending device, and the psychological problems of users' fear of using it all lead to the fact that there are not many families or users who buy the descending device
In the event of a fire, even if the user prepares the descending device, there are still problems when using it. The user needs to install and fix the descending device and connect and wear the safety belt in a short time. This is a challenge for the user and is prone to error , the special problem is that when a fire breaks out, we often install and fix the descending device next to the window or balcony to escape. Or the escape device is a friction type, which is most afraid of water infiltration. The infiltration of water will reduce the friction and cause the failure of the descent device or escape device. In addition, when a fire occurs, the flame often spreads to the outside of the window or balcony, and the high temperature of the flame It will also disable the descent device or escape device

Embodiment Construction

[0030] Such as figure 1 as shown, figure 1 It is a schematic diagram of the descending device according to the first embodiment of the present application, viewed from top to bottom. The descending device 1 includes a descending device 2, a winding turntable 3, a flywheel 5, and a housing 6. The descending device 2 is fixed on the housing 6, the winding turntable 3 is arranged on the housing 6 through bearings, and the flywheel 5 is arranged on the winding turntable 3, and the first part 13 of the circulating slow-down rope 7 enters the slow-down from the opening of the slow-down device 2. The second part 9 of the above-mentioned circular slow-down rope 7 is formed by extending from the opening of the slow-down device 2 and from the opening of the slow-down device 2. The second part 9 of the above-mentioned cycle of slow-down rope 7 coils around the winding turntable 3 and then passes through the anti-falling The pulley 12 extends out of the slow-down device 1, the above-ment...

Abstract

The invention relates to a building with a descent control device. The descent control device comprises a descent control device body and a winding rotary disc or a rotating shaft. The descent control device is arranged on a roof, or a refuge floor or a middle floor of the building. A circulating descent control rope enters the descent control device body and extends out of the descent control device body. The circulating descent control rope extends outwardly after winding around the winding rotary disc or the rotating shaft, and the circulating descent control rope can drive the winding rotary disc or the rotating shaft to rotate. The winding rotary disc or the rotating shaft is connected with a rotator. The circulating descent control rope is arranged beside windows or balconies of the outer wall of the building or inside the outer wall beside the external openings of the outer wall or inside an embedded pipe on the outer side of the outer wall of the building in an extending mode.

Description

technical field [0001] The application belongs to a building provided with a descending device. 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 an arm-raising fire truck used for existing fire rescue and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, which is approximately equivalent to a height of 15 floors. Most of the ti...
