Speed difference falling protector provided with reverse locking mechanism and used for high-altitude operation of electric power iron tower

Abstract

The invention relates to the technical field of falling prevention, in particular to a speed difference falling protector provided with a reverse locking mechanism and used for high-altitude operation of an electric power iron tower. The falling protector comprises an anti-falling device and an ascending device arranged on the side edge of the anti-falling device, and the anti-falling device comprises a shell and a mounting disc. In the speed difference falling protector provided with the reverse locking mechanism and used for the high-altitude operation of the electric power iron tower, by arranging a driving part, when an operator is in a suspended state, the driving part is pulled, and the driving part drives a rotating plate to rotate through a rotating disc. The rotating plate drives the mounting disc to rotate through a rotating ring, the mounting disc rotates to wind a connecting rope, then the operator is driven to ascend, thus the operator does not need to wait for rescue workers, time is saved, and the problems that when the operator falls for a long distance, the operator is far away from the iron tower due to the long falling distance, a current falling protector cannot achieve the rising effect, as a result, the operator cannot grasp the iron tower on the top, and the working efficiency is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of anti-falling, in particular to a speed difference anti-falling device with a reverse locking mechanism for high-altitude operation of electric iron towers. Background technique [0002] The anti-drop device, also known as the speed difference device, is a product that plays a protective role. It can quickly brake and lock falling objects within a limited distance. It is suitable for cargo hoisting and high-altitude operations. It can prevent damage to the suspended workpiece and protect the safety of the operator. [0003] When working on the power tower, fix the hook at the top of the fall arrester on the fixed object, and hang the hook at the bottom on the operator. At this time, the operator can climb and move on the tower. When the staff makes a mistake When falling, the pull-out speed of the safety rope in the safety device will be significantly accelerated, and the internal pawl will block the fast...

AI Technical Summary

Problems solved by technology

[0003] When working on the power tower, fix the hook at the top of the fall arrester on the fixed object, and hang the hook at the bottom on the operator. At this time, the operator can climb and move on the tower. When the staff makes a mistake When falling, the pull-out speed of the safety rope in the safety device will be significantly accelerated, and the internal pawl will block the fast-rotating ratchet, so as to realize the automatic locking of reverse rotation; but when the operator falls the distance For a long time, the operator will be in a suspended state at this time. Due to the long distance of falling, the distance between the operator and the iron tower is relatively long. Living on the top of the iron tower, you can only seek rescue, resulting in reduced work efficiency
