Abstract

The utility model provides an aerial lowerator, which is used for overcoming the defects of unreasonable stress structure of a crankshaft, the absence of a disclosed rope rewinding technology and potential risk and inconvenience in use for a user existing in the conventional aerial lowerator with the crankshaft and a speed-limiting piston. The principle of the aerial lowerator is that: both sides of a rope drum are provided with movable rotating components which rotate synchronously; the crankshaft is arranged between rotating parts of the synchronous rotating components to solve the problem of non-uniform stress; a one-way rotating member is arranged, so that the crankshaft is driven to revolve when a rope is used for driving the rope drum to rotate towards one direction under the action of gravity, and the revolving crankshaft is used for driving a hydraulic speed-limiting component to move; and when the rope drum rotates towards an opposite direction, the crankshaft does not revolve, and the hydraulic speed-limiting component does not move, so that the problem of rope rewinding is solved.

Description

A kind of aerial downfall equipment

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, there is the irrational problem of bent axle force structure, simultaneously, do not disclose the technology that rope unrolls yet, not only cause certain potential danger, bring the inconvenience of use yet to the user.

Summary of the invention

There is the unreasonable and rope technology of unrolling openly of bent axle force structure in order to overcome the aerial downfall equipment that adopts bent axle and speed limit piston now, cause potential danger and awkward shortcoming to the user, the present invention proposes a kind of aerial landing-gear, its principle is: the moving assembly of rotation that synchronous rotation is set in the both sides of rope drum, bent axle is mounted between the tumbler of synchronous runner assembly thereby has solved the problem of unbalance stress, and by the one-directional rotation member is set, under the effect of rope, drive the rope drum and rotate and drive crank up towards a direction at gravity, drive the action of hydraulic pressure speed limit assembly during crank up, but bent axle does not turn round when the rope drum rotates in the opposite direction, hydraulic pressure speed limit assembly is failure to actuate, thereby the solution rope unrolls.
