Description

Technical Field

[0001] The utility model relates to the field of railway traffic engineering, in particular to a contact network support pillar based on a high platform and convenient for maintenance. Background Art

[0002] With the rapid development of railway transportation and the growing demand for passenger travel, improving the quality of railway transportation services and optimizing the passenger experience have become urgent issues to be addressed by the railway department. Among them, the transformation of low platforms into high platforms has become one of the important measures to improve service quality. The design of high platforms enables passengers to get on and off the train more conveniently, improving the efficiency and safety of riding. However, the construction of high platforms has also brought new challenges to the existing contact network pillars on the platform. Contact network pillars are important facilities that support the contact network. Their stability and reliability are directly related to the normal operation of the railway power supply system.

[0003] During the transformation of high platforms, if the original contact network pillars are directly dismantled and rebuilt, it will not only increase a lot of investment costs and cause waste of resources, but also may cause unnecessary interference and impact on existing lines during the dismantling and reconstruction process. If the existing contact network pillars are directly landfilled, although the interference problem to the high platform can be solved, this method is not conducive to the inspection and maintenance of the contact network pillars. For this reason, we propose a contact network pillar based on the high platform that is easy to inspect. Utility Model Content
