Problems solved by technology

[0002] Usually the catenary arm is only cut and installed in the factory when the catenary arm is processed, and the installation of most parts is completed on site. Therefore, the prefabrication process and quality of the catenary arm are difficult to control
Due to the difficulty of on-site construction and verification, converting high-altitude operations to ground construction and completing the installation of components on site will increase unnecessary workload and safety risks, and the original construction method must be verified on site

Abstract

The invention discloses an electrified overhead line system cantilever prefabrication platform. The electrified overhead line system cantilever prefabrication platform comprises one set of cantilever measurement and cutting platform, one set of positioning pipe prefabrication platform, two sets of cantilever prefabrication platforms and one set of recheck platform, wherein the cantilever measurement and cutting platform, the positioning pipe prefabrication platform, the cantilever prefabrication platforms and the recheck platform form one whole set of complete machining chain, and synchronously satisfy the requirements for integration of measurement, machining and recheck. The electrified overhead line system cantilever prefabrication platform performs control according to the procedures of cantilever cutting, part prefabrication, fastening, selective examination and recording, adopts a mode of signing, hand-over, recording and filing for each procedure, performs the quality control in a workshop, solves the problem of difficulty in controlling the site construction quality, and realizes unified mounting, fastening construction and checking in factories, and guarantees safety, high quality and ordered control. A remarkable effect is achieved in actual application.

Description

technical field [0001] The invention relates to the field of electrified railways, in particular to a prefabricated platform for electrified catenary arm arms. Background technique [0002] Usually the catenary arm is only finished cutting and installing the catenary cable seat during processing in the factory, and the installation of most parts is completed on site. Therefore, the prefabricated process and quality of the catenary arm are difficult to control. Due to the difficulty of on-site construction and verification, converting high-altitude operations to ground construction and completing the installation of components on site will increase unnecessary workload and safety risks, and the original construction method must be verified on site. [0003] The invention solves the disadvantage that it is difficult to control the quality of on-site construction, and realizes the unified installation, fastening construction and inspection in the factory, and the safety and qua...
