Building with multifunctional rope unwinding device

Abstract

Provided is a building or a structure with a multifunctional rope unwinding device. The multifunctional rope unwinding device is arranged on a roof of the building, and comprises an electric power transmission system or a hydraulic transmission system or a pneumatic transmission system, a coiling block or a rotating shaft and a pulling rope; a rotating shaft of a motor of the electric power transmission system or the hydraulic transmission system or the pneumatic transmission system is connected with the coiling block or the rotating shaft directly or through a transmission element and can beused for driving the coiling block or the rotating shaft to rotate; the coiling block or the rotating shaft is sleeved with a ring; the ring can rotate around the coiling block or the rotating shaft and is provided with a blocking surface; the coiling block is provided with a blocking piece; one end of the pulling rope is connected to the ring; after extending out of the ring and being wound on the coiling block or the rotating shaft, the pulling rope is connected with a heavy object; and a cable connected with an electromotor is connected with a power source through an electric device elementcapable of switching on or off the power source above the building provided with the multifunctional rope unwinding device.

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 or structures have always drawn people's attention. In the event of a fire, the reliability of fire elevators is worth pondering. There is also an arm-raising fire truck used in existing firefighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters. Rescue people, and 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. Once the above-mentioned high-rise buildings or structures catch 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, but some high-rise buildings or structures have incomplete fire-fighting facilities, and the existence of fi...

Problems solved by technology

[0022] After studying the use process of the above-mentioned existing descending device and the user's feelings, it is found that the existing descending device with the descending rope has many shortcomings: this descending device is provided on the floor of the fire place to provide This floor is used by escape personnel, because this floor is the ignition point of fire, which is a threat to the descending device suspended on this floor, and the existing descending device needs to be inspected regularly. Generally, individual buyers lack this awareness due to troubles, which also poses a threat to The normal use of the descending device has caused potential hidden dangers, and there have been casualty accidents using the descending device; the descending height of the existing descending devices with descending ropes is controlled below 100 meters. The volume and weight of the descending device is large, and it is difficult for individual users to hang it on the window, and the descending rope with a length of more than 100 meters is large in size and weight. It is not only difficult for the user to throw such a descending rope downward, but also because Due to the tail effect, the dropped slow-down rope will also accidentally injure the people under the building or the glass of the outer wall. At the same time, the weight and impact of the dropped slow-down rope will also cause damage to the internal structure of the slow-down device.

Moreover, many existing escape products and escape rescue programs have caused many adverse effects on the original building, such as occupying the area of ​​the building or occupying the distance between buildings, or having a great impact on the structure of the original building, etc.
