Problems solved by technology

[0003] In order to overcome the disadvantages that the known aerial descender is not equipped with a rope rewinding member, there is difficulty in rewinding the rope, affecting repeated use, and affecting safety and lifesaving. The present invention proposes an aerial descender. The principle is: A one-way rotating member is arranged between them. When the rope is lowered, the rope rotates around the disk and drives the crankshaft to rotate. The crankshaft produces no resistance

Abstract

The invention relates to a flight dropper for overcoming the defects that a well-known flight dropper without a rope rewinding member has difficulty in rope rewinding to influence repeated use and safe rescue. The flight dropper provided by the invention has the principle that a one-way rotating member is arranged between a rope winder and a crankshaft; when the rope falls, the rope winder revolves and drives the crankshaft to rotate, and the crankshaft revolves and drives a piston rod to operate; and when the rope is rewound, the rope winder rotates, but the crankshaft does not revolve, and a piston does not generate resistance to the crankshaft since the crankshaft does not revolve. By the one-way rotating member arranged between the rope winder and the crankshaft, a user can conveniently and rapidly rewind the rope, and the invention is rapid and repeated to use and favorable to safe rescue.

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 ...
