Abstract

The invention provides an aerial landing device and aims to solve the problems that the aerial landing devices using crankshafts and speed limit pistons are unreasonable in crankshaft stress structure and inconvenient to use and cause potential risks to users, and the rope backward winding technology is not disclosed. According to the technical scheme, rotation components which rotate synchronously are disposed on two sides of a rope winding reel, the aerial landing device is provided with two set of hydraulic speed limit device, when one set of the hydraulic speed limit device is idle, the other set of the hydraulic speed limit device is not idle, and accordingly uneven stress is avoided. Since a one-way rotation device is disposed, the crankshaft is driven to rotate backwardly when the rope drives the rope winding reel to rotate in one direction under the action of gravity, and the backward rotation of the crankshaft drives hydraulic speed limit components to operate. When the rope winding reel rotates in a reverse direction, the crankshaft does not rotate backwardly, so that the hydraulic speed limit components does not operate and rope backward winding is avoided.

Description

A kind of aerial lowerator

Technical field

The present invention relates to a kind of landing-gear, particularly relate to a kind of hydraulic speed-limiting aerial lowerator.

Background technology

In daily life or work, people often can face a danger aloft, if when not having other method to escape, need to escape by air landing device, known air landing device comprises friction speed-limited, hand brake speed-limited and hydraulic damping speed-limited, the above two shortcomings are poor reliability, most the latter is relatively simple for structure, performance is also reliable, CN87216143 discloses the air landing device that a kind of piston and cam play speed limit effect, but cam only bears pressure, do not bear pulling force, in descent, there is speed limit uneven; ZL2003101127389 with ZL2003201232361 individually discloses a kind of principle adopting bent axle to be connected with Hydraulic Adjustable Speed formula controller, but owing to adopting chain ladder, descent altitude is restricted; ZL2007202016917 discloses a kind of hydraulic speed-limiting formula aerial lowerator, and its structure was rope type, must first correctly put on lifesaving rope, cause certain trouble to user during use; In the aerial lowerator adopting bent axle and speed limit piston now, because speed limit piston is Passive part, crankshaft two end unbalance stress, and bent axle is constantly in the middle of the unloaded and fully loaded state hocketed, the irrational problem of bent axle force structure, meanwhile, does not disclose the technology that rope unrolls yet, not only cause certain potential danger to user, also bring the inconvenience of use.

Summary of the invention

In order to overcome, to adopt the aerial lowerator of bent axle and speed limit piston to there is bent axle force structure now unreasonable and disclose rope and to unroll technology, potential danger and awkward shortcoming is caused to user, the present invention proposes a kind of aerial lowerator, its principle is: arrange the runner assembly of synchronous axial system in the both sides of rope drum and adopt two cover hydraulic speed limiting devices, when a cover hydraulic speed limiting device is in idle position, another cover hydraulic speed limiting device is not in idle position, thus solves the problem of unbalance stress; And by arranging single direction turning mechanism, crank up is driven when rope drives rope drum to rotate towards a direction under gravity, the action of hydraulic speed-limiting assembly is driven during crank up, but bent axle does not turn round when rope drum rotates in the opposite direction, hydraulic speed-limiting assembly is failure to actuate, and thus solves rope and unrolls.
