Description

TECHNICAL FIELD

[0001] The application relates to the technical field of railway engineering vehicles, in particular to a limiting support for welding engineering vehicle parts. BACKGROUND

[0002] A railway engineering vehicle refers to a special vehicle designed and manufactured for railway construction, maintenance and operation engineering operations, and running on a railway track. It is usually equipped with specific working devices or equipment and can complete various tasks related to railway engineering, and is an indispensable important equipment in railway engineering operations.

[0003] For example, the Chinese utility model patent with the publication number "CN218575388U" discloses a welding fixing support. In the production and manufacturing of engineering vehicle cab floor, the plate needs to be welded along the long edge and the short edge. When welding along the long edge, the second limiting and clamping structure, i.e. the second pressing plate and the pressing plate, are used to clamp the workpiece, so that the workpiece is in a vertical state, and then the butt joint of the workpiece is welded. When welding along the short edge, the workpiece is placed on the positioning plate, and the pressing plate clamps the workpiece, and the short edge is welded. Alternatively, the workpiece is placed on the pressing plate, and the second pressing plate is used to realize horizontal clamping, and then welding is performed. Since the lengths of the positioning plate and the pressing plate are different, the applicability of the workpiece is improved.

[0004] In the above-mentioned patent, different sizes of workpieces can be clamped, and different clamping methods can be replaced to adapt to different welding methods. However, when welding parts with special angle requirements, it is difficult for the device to adjust the angle of the clamping structure, which requires workers to manually adjust the angle of the parts during the welding process, which not only reduces the welding efficiency, but also makes it difficult to ensure the accuracy of the welding angle, thereby affecting the welding quality.
