Multi-friction-wheel controllable brake swing-type high-rise rescue device

Abstract

The invention belongs to the technical field of high-rise rescue, and relates to a multi-friction-wheel controllable brake swing-type high-rise rescue device. A wire rope released and collected by a host is released and collected by virtue of a guide rail type rope releasing and collecting mechanism; the host is provided with a lever type brake mechanism, a centrifugal reduction gear, a double-friction-wheel linked brake mechanism and a manual wire rope winding mechanism; the lever type brake mechanism is cooperated with a main spindle of the host; more than one safety seat basket for bearing a human body is hung on a connecting rod arranged on adjustment levers on two sides of the lever type brake mechanism. The multi-friction-wheel controllable brake swing-type high-rise rescue device has the advantages that the structure is more perfect, the rescue device is safer and more reliable to use, and is higher in practicability, especially, the double-friction-wheel linked brake mechanism can ensure that the brake is powerful, the stress is symmetrical and the like, and the rescue device is suitable for high-rise rescue, fire fighting rescue and rock climbing rescue.

Description

technical field [0001] The invention belongs to the technical field of high-rise rescue, in particular to a multi-friction wheel controllable brake swing type high-rise rescue device. Background technique [0002] With the application of building materials in the construction industry, the development of construction technology and the increase of population, the land use area decreases, and the floors used by people for office or residence are getting higher and higher. However, in recent years, fires in high-rise buildings at home and abroad Occurs constantly, due to the lack of escape equipment, every time a fire is accompanied by a large number of people's death, serious injury or disability, although there are also some high-rise escape equipment that have patent applications or are put into the market, the disadvantages are: first, poor safety, resulting in a wide range of applications It is limited and cannot be popularized. For example, when the cable is released, th...

[0002] With the application of building materials in the construction industry, the development of construction technology and the increase of population, the land use area decreases, and the floors used by people for office or residence are getting higher and higher. However, in recent years, fires in high-rise buildings at home and abroad Occurs constantly, due to the lack of escape equipment, every time a fire is accompanied by a large number of people's death, serious injury or disability, although there are also some high-rise escape equipment that have patent applications or are put into the market, the disadvantages are: first, poor safety, resulting in a wide range of applications It is limited and cannot be popularized. For example, when the cable is released, the life-saving equipment fails due to the winding of the cable, so that the victims cannot escape in time; second, the structure is complex, the production cost is high, and it is inconvenient to use; Time-to-use installation is not conducive to timely escape
