Bidirectional landing speed-reduction device

Abstract

The invention relates to a bidirectional landing speed-reduction device. The bidirectional landing speed-reduction device comprises a shell, a drive shaft and ropes. The drive shaft comprises a driving shaft and a driven shaft. A driving gear is coaxially mounted on the driving shaft. The driven shaft is coaxially sleeved with a driven gear. The driven gear and the driving gear are assembled in an engaged mode. A centrifugal speed reducer which is coaxial with the driven shaft is mounted on the outer side of the upper top surface of the shell. The bidirectional landing speed-reduction device is scientific and reasonable in design and simple in structure; the bidirectional landing speed-reduction device is different from a unidirectional landing speed-reduction device in that the two ropes are wound on the drive shaft in a bidirectional mode so that both unidirectional landing and bidirectional landing can be achieved, using cost is reduced, and using efficiency is improved; and the bidirectional landing speed-reduction device is suitable for emergent forced landing of airplanes or emergent escape under high-altitude building fires and dangerous conditions and can also be popularized to other application fields.

Description

technical field [0001] The invention belongs to the field of emergency landing auxiliary equipment, and relates to a landing deceleration device, in particular to a two-way landing deceleration device. Background technique [0002] Emergency landing aids are required for emergency landing of aircraft, fire in high-altitude buildings, and emergency escape from danger. In the prior art, one end of a rope is usually fixed, and the other end is tied to the landing personnel or objects. However, during the high-altitude landing, due to the Due to the effect of its own weight, with the increase of displacement, the descending speed continues to increase, resulting in faster and faster descending speed. There is a certain danger, and there is a greater safety hazard for the safety of people and items. Therefore, it is necessary to pass certain measures. The deceleration means or deceleration device realizes the deceleration of the landing. Through the retrieval of the prior art, no...

Problems solved by technology

[0002] When an aircraft makes an emergency landing or a fire in a high-altitude building or an emergency escape in a dangerous situation, emergency landing auxiliary equipment is required. In the prior art, one end of the rope is usually fixed, and the other end is tied to the landing person or object. However, during the high-altitude landing process, due to Due to the effect of its own weight, as the displacement increases, the descending speed continues to increase, resulting in faster and faster descending speeds. The deceleration means or deceleration device realizes the deceleration of the landing. Through the search of the existing technology, no effective and feasible rope emergency landing deceleration technical solution has been found.
