Description

Technical Field

[0001] The utility model belongs to the technical field of wire feeding mechanisms, and particularly relates to a wire feeding mechanism for track welding. Background Art

[0002] Track welding is an important link in railway engineering, mainly used for welding steel rails into continuous tracks. When performing track welding, a wire feeding mechanism is required to transport welding wires. However, the wire feeding mechanism has the following deficiencies during use:

[0003] 1. Some existing wire feeding mechanisms are not easy to adjust and are not suitable for different types of welding wires. When the welding wire needs to be replaced, a large amount of adjustment work may be required, which may reduce work efficiency.

[0004] 2. At the same time, the guiding of some wire feeding mechanisms during wire transportation is not stable enough. Therefore, the welding wire may be wound or disordered, affecting the continuity and stability of wire feeding.

[0005] Therefore, we have proposed a wire feeding mechanism for track welding. Content of the Utility Model

[0006] The purpose of the utility model is to solve the problems existing in the prior art that some wire feeding mechanisms are not easy to adjust and are not suitable for different types of welding wires. When the welding wire needs to be replaced, a large amount of adjustment work may be required, which may reduce work efficiency. At the same time, the guiding of some wire feeding mechanisms during wire transportation is not stable enough. Therefore, the welding wire may be wound or disordered, affecting the continuity and stability of wire feeding. A wire feeding mechanism for track welding is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:
