Complete dropper prefabrication platform for high speed railway overhead line system

Abstract

The invention discloses a complete dropper prefabrication platform for a high speed railway overhead line system. The complete dropper prefabrication platform includes a rotatable fixing rod, a hydraulic clamp, a fixing block, a graduated scale, wire clippers, a sliding module and extrusion flat steel, the tip of the hydraulic clamp is welded and fixed at the top of the platform, the rotatable fixing rod is positioned on one side of the hydraulic clamp, the graduated scale is positioned on the other side of the hydraulic clamp, the sliding module is positioned on one side of the graduated scale and parallel to the graduated scale, the wire clippers are positioned on the side, far from the graduated scale, of the sliding module, and the wire clippers are fixed on the side, far from the rotatable fixing rod, of the hydraulic clamp. Through the reasonable layout of the hydraulic clamp, the wire clippers, the fixing block, the graduated scale, the sliding module and other functional modules on the platform, a complete dropper for the overhead line system is fabricated conveniently and accurately; since the whole prefabrication process is simple and easy to learn, an ordinary worker is capable of mastering the crimping essentials in 10 min and performing prefabrication independently, so that the efficiency and quality of the complete dropper prefabrication construction are enhanced. The complete dropper prefabrication platform is suitable for standardized and industrialized production.

Description

technical field [0001] The invention relates to the field of electrified railways, in particular to a prefabricated platform for integral hanging strings of a high-speed railway catenary. Background technique [0002] The prefabrication of catenary hanging strings is a key control process for the construction quality of high-speed railway catenary projects, and it is also the first condition to ensure that the on-site installation and adjustment are in place at one time. At present, the high-speed railway catenary adopts non-adjustable current-carrying integral suspension strings, and has a heart-shaped ring and an equipotential current-carrying ring structure. However, the existing overall hanging strings adopt simple ruler measurement and crimping, which leads to low construction efficiency and inaccurate control of the hanging string length. Contents of the invention [0003] The purpose of the present invention is to provide a high-speed railway catenary integral susp...
