Description

Technical Field

[0001] The utility model belongs to the technical field of contact wires, and in particular relates to a fixed contact wire assembly component. Background Art

[0002] Contact wire mainly refers to the contact wire used for electrified railway contact network. Contact wire is also called tram wire. It is an important component of the contact network and is generally made into a cylindrical shape with grooves on both sides. The groove is to facilitate the installation of wire clamps and suspend the contact wire without affecting the sliding current collection of the pantograph slide. The part of the contact wire that contacts the pantograph slide is in an arc shape, which is called the working surface of the contact wire. The contact wire directly transmits current to the electric locomotive through sliding friction with the pantograph slide on the electric locomotive. Its performance directly affects the current collection quality of the electric locomotive and the safe operation of the locomotive. The contact wire has the worst working environment among all power supply wires. When working normally, it needs to withstand impact, vibration, temperature difference changes, environmental corrosion, wear, electric spark ablation and great working tension. Therefore, its performance directly affects the safe operation of high-speed trains.

[0003] When the contact line is partially damaged, worn, or broken, it is necessary to cut off the damaged part and reconnect it (using a joint wire clamp). In the prior art, the contact line will return to its original bent and deformed state after losing tension, and has great rigidity, making the two sections of the contact line difficult to control. The breakpoints of the two sections of the contact line need to be aligned manually, and there is no clamping and fixing structure. The manual labor is too large and wiring is difficult. Most of the contact lines are fixed with bolts, which is complicated to operate and easily causes connection failure. Utility Model Content
