Description

Technical Field

[0001] The present application relates to the technical field of cable installation equipment, and in particular to a cable installation equipment for a galvanized iron tower. Background Art

[0002] Long-distance power transmission refers to the process of transmitting electric energy from a power plant or power source to a load center or user over a long distance through a transmission line. In the process of long-distance power transmission, in order to reduce the loss of electric energy, ultra-high voltage transmission is often used. At the same time, in order to avoid the influence of various terrains along the route, multiple power towers will be set up along the transmission line as support points for the power transmission cables.

[0003] Among them, the power tower uses insulator strings to support and insulate the cables. However, as the service time increases, some insulators are damaged. At this time, the cables need to be temporarily separated from the insulator strings, and then new insulators are replaced. In the prior art, workers usually carry replacement tools to climb to the installation crossarm, and then one end of the rope is connected to the installation crossarm, and the other end of the rope is connected to the tensioner. The tensioner is then moved toward the cable end and fixed to the cable. The tensioner is pulled toward the installation crossarm by the rope. At this time, the connection points at both ends of the insulator are loose. The worker removes the old insulator and installs the new insulator. Finally, the rope is loosened and the tensioner is unlocked to complete the replacement of the insulator.

[0004] With respect to the above-mentioned related technologies, with the development of UHV technology, the number of insulators connected in series on an insulator string has gradually increased. When the insulators are replaced by the aforementioned method, the insulator string may become loose as a whole. Therefore, when replacing damaged insulators, the remaining insulators need to be supported to prevent them from falling. However, the insulators are heavy, and relying on manual support by the staff will result in a high labor intensity for the staff. Summary of the invention
