Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of contact network positioning structures, in particular to a positioning structure for railway contact networks. Background Art
[0002] The working principle of the positioning structure for railway contact network is to fix the contact wire at a specific position above the railway through the coordinated action of components such as locators, positioning rings and supports, so that it maintains good contact with the pantograph of the electric locomotive. When the pantograph of the electric locomotive passes, the contact wire will be subjected to horizontal and vertical forces. The positioning structure can absorb these forces and keep the position of the contact wire stable.
[0003] Most of the existing positioning structures for railway contact networks are connected by fixed connection structures. During use, the vibration of the contact network may cause the connection structure to be dislocated, resulting in an unstable connection to the contact network, which may easily cause safety hazards. Therefore, we propose a positioning structure for railway contact networks. Utility Model Content
