Movable multi-position steering pulley

Abstract

The invention discloses a movable multi-position steering pulley, which belongs to the technical field of power transmission line maintenance and comprises a movable frame, two fixing blocks are arranged on the outer side of the movable frame, a locking mechanism is arranged at the far end of the movable frame, a working mechanism is arranged at the upper end of the movable frame, and a wire walking mechanism is arranged in the movable frame. The moving frame is installed on the upper side of an existing wire through the wire walking mechanism, so that the moving frame can freely move on the upper side of the wire, then the moving frame and the tackle are connected through the working mechanism, the moving frame can synchronously move along with the tackle when the tackle moves on the upper side of the wire, and under the connecting effect of an extension rod of the working mechanism, the moving frame can move synchronously. The stability of the tackle in the moving process is improved, the instability phenomenon caused by stress of a single wheel of the tackle due to random movement and possible scratching to a wire are avoided, the labor intensity of operators in the traction process is reduced, and the operation is easier.

Description

technical field [0001] The invention belongs to the technical field of power transmission line maintenance, and in particular relates to a movable multi-position steering tackle. Background technique [0002] At present, the towers of the transmission line cross the mountains and towers, the position of the towers is large, the span is large, the ground wire sag is large, and the conductor, the ground wire breakage and the displacement of the anti-vibration hammer often occur during operation. The maintenance workers are dealing with similar defects. Many technical problems were exposed. For example, the height difference between the hanging point of the tower head and the lowest point of the sag of the wire and the ground wire is large, and the inclination angle of the ground wire is large. Using the traditional single-wire flying car will cause the flying car to tilt, and the single wheel will be stressed. The head is all climbing, which consumes a lot of physical strengt...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the existing method in the implementation process, when the existing flying car is dragged on the existing wire, the single wheel is often stressed, and it is very easy to swing in random directions to cause friction with the wire. It is a movable multi-position steering block proposed because it is easy to cause scratches on the wires while the movement is not smooth.
