Opening structure for anti-falling device, steel wire rope self-lock equipment and opening and closing method

Abstract

The invention discloses an opening structure for an anti-falling device. The opening device comprises a body, wherein the body comprises a shell, a fixed plate and a movable plate; mounting holes are symmetrically formed in the upper part and the lower part of the shell and are blind holes; compression springs and buttons are arranged inside the mounting holes, while the front ends of the buttons are arranged on the compression springs; limiting slots are formed in the tail parts of the buttons, the buttons are fixed on the shell through screws which penetrate through screw holes and the limiting slots; location holes are symmetrically formed in the upper part and the lower part of the movable plate, and the buttons are arranged in the location holes in a penetrating manner so as to prevent horizontal movement of the movable plate; a sliding groove is formed in one side, opposite to an opening direction, of each location hole. The opening structure, disclosed by the invention, can be opened by pressing two buttons at the same time and then outward pulling the movable plate, prevents the danger caused by opening the anti-falling device by mistake by accidentally touching one button, so that the opening device not only is high in safety, but also is good in operation comfort degree.

Description

technical field [0001] The invention relates to the technical field of anti-fall technology for working at heights, in particular to an opening structure of an anti-fall device, a wire rope self-locking device and a switch method. Background technique [0002] As safety protection is getting more and more attention, especially the anti-fall devices used to protect workers at heights, in addition to the safety requirements of traditional anti-fall equipment, the ease of operation of the product and the comfort of the staff are also important. put forward higher requirements. [0003] In GB 24542-2009 "Self-locking device with rigid guide rail for fall protection", GB / T 24537-2009 "Self-locking device with flexible guide rail for fall protection" and other series of standards for fall protection devices, the requirements for fall protection devices have Two consecutive unambiguous opening actions are required. The existing anti-fall device usually has two relatively complica...
