A fall arrester for working at heights

Abstract

The present invention relates to the technical field of fall arresters, more specifically, a fall arrester for working at heights, comprising a fall arrester shell, a first connecting hook, a second connecting hook connected to the fall arrester shell through a connecting rope, and Rotate the reel installed in the shell of the fall arrester, the reel is wound with a safety rope, and the safety rope is connected to the first connecting hook, and the fall arrester shell is provided with an anti-fall lock The anti-fall locking mechanism includes a ratchet wheel fixedly installed in the shell of the anti-fall device, a locking disc coaxially fixedly installed with the reel, and multiple groups of locking units arranged circumferentially on the locking disc; the entire Compared with the traditional fall arrester, the device has higher sensitivity, can trigger the locking work at the moment of accident, and can easily reset the internal locking structure without disassembling the device, which has high practicability.

Description

technical field [0001] The invention relates to the technical field of fall arresters, more specifically, to a fall arrester for high-altitude operations. Background technique [0002] The anti-drop device, also known as the speed difference device, is a product that plays a protective role. There is a locking mechanism inside the fall arrester. When the fall arrester is working normally, it is in a semi-tension state, so that the operator has no sense of worry. In case of a fall, the pulling speed of the safety rope is obviously accelerated, and the locking mechanism inside the device is automatically locked. [0003] The existing fall arrester has a simple structure and low sensitivity, so that the displacement of the staff working at heights is often large when they fall, which may cause certain damage to the human body, and the internal locking structure of the existing fall arrester triggers work. , it needs to be disassembled and reset, which is very inconvenient. ...
