Rope pressing device of rope descent control device

Abstract

The invention relates to a rope pressing device of a rope descent control device, which overcomes the problem that the rope pressing device of the rope descent control device in a rope through structure disclosed at present is small in rope pressing wrap angle and poor in rope pressing effect. The invention provides the rope pressing device of the rope descent control device. The rope pressing device of the rope descent control device mainly comprises a rope, a rope pressing wheel, a wheel shaft, a wheel shaft base, a supporting shaft, a supporting shaft base, a shaft end fixing piece, a pressing piece, a body, and a rope winded wheel. The rope is winded on the rope winded wheel, the rope pressing wheel is installed on the wheel shaft and fixed on the wheel shaft base through the shaft end fixing piece, and the wheel shaft base is installed on the supporting shaft base through the supporting shaft and fixedly installed on the body through the shaft end fixing piece. One end of the pressing piece is fixedly arranged on the body, while the other end of the pressing piece is further provided with a buckling piece. The rope pressing device of the rope descent control device is characterized in that the rope pressing wheel is installed above the rope winded wheel and placed in a rope slot of the rope winded wheel, and the pressing piece is tensioned and pressed on the wheel shaft base. The rope pressing device provided by the invention can be installed above the rope winded wheel, so that the rope pressing wrap angle can be increased, and therefore, the rope pressing effect is further improved.

Description

technical field [0001] The invention relates to a rope slow descending device, in particular to a rope pressing device of the rope slow descending 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 by means of air landing devices. Known air landing devices include friction speed limiting, manual braking speed limiting and Hydraulic damping speed-limiting type, the first two disadvantages are 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 a piston and a cam to limit the speed, but the cam only bears pressure and does not bear pressure. Pull force, there is uneven speed limit during the landing process; ZL2003101127389 and ZL2003201232361 respectively disclose a principle of connecting the crankshaft with a hydraulic speed-regulating control...
