Air landing device

Abstract

An air landing device. In order to overcome the disadvantage of causing potential hazards to the users as a result of the unreasonable stress structure of the crankshaft of existing air landing devices which adopt a crankshaft and a speed limit piston, the present invention provides an air landing device, the technical scheme of which is that the gravity member is supported by a carrier; the carrier is fixedly connected with a rope; the rope is enwound on a winding disc; the winding disc is fixed on a rotation shaft; the rotation shaft is mounted on a bearer by a shaft base; a rotating member is disposed on the rotation shaft; a crankshaft is disposed on the rotating member; the crankshaft is connected with the piston rod of the speed limit piston; the speed limit piston is fixed on the bearer. The invention is characterized in that a supporting pedestal, which is muff-coupled on the outer side of the rotating member, is disposed; when rotating the rotating member, the inner surface of the supporting pedestal cooperates with the outer surface of the rotating member and the supporting pedestal plays a supporting role to the rotating member. The beneficial effect of the present invention is to provide a more reasonable stress structure of the crankshaft and ensure safe use.

Description

technical field [0001] The invention relates to a landing device, in particular to an aerial landing device. Background technique [0002] In daily life or work, people often encounter danger at high places. If there is no other way to escape, they need to escape with the aid of an air landing device. The known air landing devices include friction speed limiting, manual brake speed limiting And hydraulic damping speed-limiting type, the disadvantage of the first two is poor reliability, the last one is relatively simple in structure, and its performance is also relatively reliable. CN87216143 discloses a kind of air landing device that uses piston and cam to play the role of speed-limiting, but the cam only bears pressure and does not Under tension, there is uneven speed limit during the landing process; ZL2003101127389 and ZL2003201232361 respectively disclose a principle of connecting a crankshaft with a hydraulic speed-regulating controller, but due to the use of a chain ...
