Abstract

The invention, belonging to the technical field of overhead ground wire maintenance tools for ultra-high voltage and extra-high voltage transmission lines, discloses a rope sag adjusting pulley for aground wire. The pulley comprises a clamping device for clamping a ground wire, a control device for adjusting opening or closing of the clamping device, and a roller being connected with the clampingdevice and being arranged below the clamping device. The roller is in rotation connection relative to the central shaft at the center; an arc surface recessed inwardly is formed at the outer wheel surface of the roller; and the arc surface cooperates with a rope. Therefore, a technical problem of a large working risk caused by the large galloping rope sag in the prior art is solved; and thus technical effects of reducing the rope sagging and ensuring the working safety are realized.

Description

Technical field [0001] The invention belongs to the technical field of maintenance tools for overhead ground wires of ultra-high voltage transmission lines, and more specifically, relates to a rope sag adjusting pulley for ground wires. Background technique [0002] As we all know, my country has the highest voltage transmission lines in the world. As the voltage levels of UHV and UHV transmission lines increase, the requirements for their insulation configuration have become stricter, and the towers have become taller and larger. The line pitch is also gradually increasing. [0003] The overhead insulated ground wire is responsible for lightning protection, information transmission and wire protection. During long-term operation and maintenance, it is often necessary to perform maintenance operations. One of the methods is to take the ground wire from the ground wire. For maintenance, this method requires the use of ropes to fix one end of the flying car at the end of the tower. A...
