Embodiment Construction

[0016] like figure 1 , figure 2 As shown, the device is composed of a housing, two friction sheave groups up and down the same, an active control gear shaft assembly, a slow-down rope and a high-strength suspension rope ring.

[0017] The shell includes a left shell 3 and a right shell 25, the left shell 3 and the right shell 25 are fixed by eight connecting rivets 2, and the left and right shells 3, 25 are respectively equipped with slow-down ropes up and down. 27, the upper and lower passage holes are respectively provided with a damping friction ring 1, and the tightening force handle 16 and the lower tightening force handle 15 that are sleeved on the slow-down rope 27 are connected with the housing 3, 25 by threads, and the The upper and lower tightening force handles 16, 15 can adjust the deformation of the damping friction ring 1 to change the damping friction acting on the slow-down rope 27. The high-strength suspension rope ring 26 is suspended on the device through...

Abstract

A self-controlled slow falling apparatus for high building is composed of upper and lower frictional pulley sets consisting of casing, an active control gear, two friction discs symmetrically arranged under and over said active control gear and engaged via gear, a handle connected with the axle of active control gear, a spiral axle acting on said frictional discs via bearing and disc spring, a rope passing through said upper and lower pulleys, and a high-strength rope ring for holding a person to be saved.

Description

technical field [0001] The invention belongs to a rope descending device for slowing down from high-altitude buildings or structures, high-altitude rescue and high-altitude operations, especially an automatic control slowing down device. Background technique [0002] There are many types and structures of high-altitude slow-descent devices, and their functions can realize the transfer of personnel from high altitude to low altitude. Among them, the typical rope descending patents rely on the weight of the human body as the driving force for the descent in terms of principle design, and use the rope wheel to rotate and speed up when the person is descending, and the centrifugal brake block connected with the rope wheel is moved outward and the fixed friction block The damping force is generated to achieve dynamic balance so that people can descend to a safe place at a relatively uniform descending speed. Such as my country's patent CN86207152 "high-altitude self-control safe...
