Abstract
The utility model provides a landing device in the air, which aims at overcoming the shortcoming in the prior art that the landing device in the air adopting a crank shaft and a speed limit piston is inconvenient in use, does not disclose rope rewinding technology, and brings potential danger to users, and the crank shaft is unreasonable in stressed structure. The principle is that rotating assemblies capable of rotating synchronously are arranged on two sides of a rope winding disc, and two sets of hydraulic speed limit devices are adopted. When one set of hydraulic speed limit device is in a no-load position, the other set of hydraulic speed limit device is not in the no-load position, so that the problem of uneven bearing is solved. A one-way rotating device is arranged, when a rope drives the rope winding disc to rotate under gravity towards a direction so as to drive the crank shaft to rotate, the crank shaft drives the hydraulic speed limit devices to move when rotating. When the rope winding disc rotates towards a reverse direction, the crank shaft does not rotate, and the hydraulic speed limit assembly does not move, so that the problem of rope rewinding is solved.
Description
Technical field
The present invention relates to a kind of landing-gear, relate in particular to the aerial downfall equipment of a kind of hydraulic pressure speed limit.
Background technology
In daily life or work, people face a danger aloft through regular meeting, if when not having other method to escape, need be by aerial landing-gear escape, known aerial landing-gear comprises friction speed-limited, hand brake speed-limited and hydraulic damping speed-limited, the above two shortcomings are poor reliability, the latter is relatively simple for structure, performance is also reliable, CN87216143 discloses a kind of aerial landing-gear that plays the speed limit effect with piston and cam, but cam only bears pressure, does not bear pulling force, exists speed limit inhomogeneous in the landing process; ZL2003101127389 discloses a kind of principle that adopts bent axle to be connected with Hydraulic Adjustable Speed formula controller respectively with ZL2003201232361, but owing to adopt chain ladder, descent altitude is restricted; ZL2007202016917 discloses the aerial downfall equipment of a kind of hydraulic pressure speed-limited, and its structure was the rope formula, must at first correctly put on the lifesaving rope during use, causes certain trouble to the user; In the aerial downfall equipment that adopts bent axle and speed limit piston now, because the speed limit piston is a Passive part, the crankshaft two end unbalance stress, and bent axle constantly is in the middle of the unloaded and fully loaded state that hockets, the irrational problem of bent axle force structure simultaneously, does not disclose the technology that rope unrolls yet, not only cause certain potential danger, also bring the inconvenience of use to the user.
