Description

Technical Field

[0001] The utility model relates to the technical field of rail transit flexible contact network components, in particular to a pin-type positioner positioning support for double conductors. Background Art

[0002] Positioning supports and positioners are important suspension products in the flexible contact network power supply system of electrified railways and urban rail transit. Positioning supports are installed on positioning tubes or positioning columns and inclined wrist arms, and the position of the contact wire is fixed by positioners and positioning wire clamps. The existing double positioning supports all adopt a hook-and-loop connection structure, and the front end of the positioner is a positioning hook, which cooperates with the hook and loop of the positioning ring or the long positioning ring. Due to the relative friction of this type of hook-and-loop connection, the surface anti-corrosion layer and the body of the parts are prone to wear; when encountering strong winds or special stress conditions, the positioner is easy to fall off from the hook and loop, causing "unhooking" and affecting driving safety. Due to the limitations of the positioning support of the pin-type positioner used for double conductors, the pin-type positioner has not yet been used in the domestic double conductor contact network system.

[0003] For example, the pin-type positioner support for double conductors disclosed in the authorization announcement number CN 207173348 U realizes the reliable connection strength between the positioner and the positioner of the articulated elastic limit positioner, is not prone to wear and electrical corrosion, and the torsion spring set on the transverse pin can overcome the deadweight of the positioner, reduce the pressure on the contact wire, and thus reduce the wear of the pantograph and the contact wire. However, it does not solve the problem that the existing tools of different sizes and heights cannot be fixed according to the actual situation. For this reason, we propose a pin-type positioner support for double conductors. Utility Model Content
