Technical Field

[0001] The utility model relates to the technical field of railway contact network manufacturing, in particular to a contact network supporting piece welding tool. Background Art

[0002] The overhead contact network is a high-voltage transmission line that is set up in a zigzag shape above the rails in an electrified railway. The support is one of the main parts of the overhead contact network. At present, the most commonly used are steel structure supports, most of which are welded and installed in a triangular manner to improve stability.

[0003] At present, the existing Chinese patent with the publication number CN214558723U discloses a positioning welding tool for contact network parts, specifically disclosing an operating table, wherein the upper front part of the operating table is provided with two horizontal arc plates, and the lower part is provided with two inclined arc plates, and the two steel pipe bodies are supported by the four arc plates, wherein the upper front part of the operating table is located at the positions of the two ends of the corresponding steel pipe body and is also provided with a positioning mechanism and a fixing mechanism for positioning and clamping the steel pipe body, and the lower front end of the operating table is located at the position of the lower end of the corresponding steel pipe body and is also provided with a fixing mechanism, so that the upper end of the steel pipe body fits the pipe body of another steel pipe body. However, there are some shortcomings in the positioning welding tool: 1. The positioning mechanism and the fixing mechanism need to cooperate to fix the axial position of the corresponding steel pipe body, and the fixing mechanism is required to fix the axial position of the corresponding steel pipe body, resulting in a more complicated structure; 2. The welding point of the two steel pipe bodies to be welded together is only exposed in the front area, so the two steel pipe bodies located on the positioning welding tool cannot be fully welded, and need to be removed and welded again.

[0004] To this end, we have designed a contact network support welding tool to solve at least one of the above-mentioned defects. Utility Model Content
