Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, specifically to an auxiliary device for welding process pipelines. Background Technology

[0002] Pipe welding refers to the connection of pipe fittings to pipes using welding methods. This includes products such as elbows, flanges, tees, reducers, and end caps. Fusion welding or brazing can be used, with the latter often used for copper pipes. Pipe fittings are parts that connect pipes to form pipelines. Based on the connection method, they can be divided into socket fittings, flexible double-fusion fittings, threaded fittings, flange fittings, and welded fittings. They are mostly made of the same material as the pipes.

[0003] A search revealed an existing patent (publication number: CN220462829U) that discloses a pipe welding auxiliary device. This device comprises a base, a lead screw, and a first motor. A fixed auxiliary support is provided on one side of the upper surface of the base. The lead screw is rotatably mounted inside the base, and a sliding seat is threaded onto the lead screw's body. The top of the sliding seat slides through the base, and a movable auxiliary support is mounted on the top of the sliding seat. The first motor is connected to the base, and its output shaft is drively connected to the lead screw. This application uses the first motor to drive the lead screw to rotate, causing the sliding seat on the lead screw to move the movable auxiliary support, adjusting the position between the movable and fixed auxiliary supports. This allows the movable and fixed auxiliary supports to provide auxiliary support for pipes of different specifications, offering strong versatility and ease of use.

[0004] However, the above solution still has some shortcomings. When carrying it or connecting additional pipes to existing installed pipes, the device is relatively large and inconvenient to carry, resulting in low convenience.

[0005] In view of this, the present invention proposes an auxiliary device for welding process pipelines. Utility Model Content
