A pipeline welding butt joint supporting device comprises an upper supporting frame (1) and a lower supporting frame (2), the upper supporting frame and the lower supporting frame are fixedly connected into a whole, a threaded rod (3) is connected to the inclined face of one side of the upper supporting frame, and the inclined face of the other side of the upper supporting frame is fixedly connected with one end of an adjusting chain (4). A threaded rod can be inserted into the inserting hole of the adjusting chain, and a locking nut (5) is screwed into the threaded rod. The device is applied to the field of welding.

Description

Technical Field

[0001] The utility model relates to a pipeline welding butt support device. Background Art

[0002] At present, sometimes the pipeline needs to be extended or connected to other equipment, which requires connecting two pipes together to form a whole to ensure the transmission and use of the fluid. In addition, if the pipeline is damaged or needs repair, it is also necessary to connect and repair the pipeline. Welding connection is a common way to connect pipelines. Welding connection has high strength and is not prone to leakage. When welding the two pipe ports, ensure that the ports are aligned. For example, when welding, the offset of the weld position at the pipe port may make the pipeline installation difficult. In the medium conveying pipeline, the position and misalignment of the weld will affect the flow of the medium and even affect the flow rate. At the same time, welding deviation will also make the overall appearance of the pipeline unsightly. Summary of the invention

[0003] The utility model aims to provide a pipeline welding butt support device.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A pipeline welding butt support device comprises an upper support frame and a lower support frame, wherein the upper support frame and the lower support frame are fixedly connected as a whole, a threaded rod is connected to an inclined surface on one side of the upper support frame, and the inclined surface on the other side of the upper support frame is fixedly connected to one end of an adjusting chain, the insertion hole of the chain can be inserted into the threaded rod, and a locking nut is screwed into the threaded rod.

[0006] The pipeline welding butt support device, the upper support frame and the lower support frame have the same structure but different lengths, and the upper support frame and the lower support frame adopt angle steel structure.

[0007] The pipeline welding butt support device, the inclined surface of the upper support frame and the threaded rod are vertically fixedly connected Beneficial Effects

[0008] 1. The utility model is provided with an adjusting chain and a threaded rod on the upper support frame. Through the cooperation between the adjusting chain and the threaded rod, pipes of various sizes can be supported and fixed. At the same time, the adjusting chain can press the pipe at the end, so that the pipe is parallel to the horizontal plane, which is convenient for welding the pipe end.

[0009] 2. The utility model can prevent the weld position from shifting when welding the end of the pipeline, avoid difficulties in pipeline installation, reduce the deviation of the pipeline after welding, and ensure the beauty of the overall appearance.

[0010] 3. The utility model inserts the insertion hole between two adjacent links on the adjusting chain into the threaded rod, and tightens the threaded rod with a locking nut. The adjusting chain will press the upper part of the pipe end to prevent the tail of the pipe from tilting, thereby ensuring the port alignment between the two pipes. The ports of the two pipes are welded together by welding to ensure the quality of the pipe welding. BRIEF DESCRIPTION OF THE DRAWINGS

The insertion hole of the adjustment chain can be inserted into the threaded rod, and a locking nut 5 is screwed into the threaded rod. The threaded rod is fixed to the inclined surface of the upper support frame by welding, and the inclined surface of the upper support frame and the threaded rod are vertically fixedly connected. One end of the adjustment chain is fixed to the inclined surface of the upper support frame by welding, and there is an insertion hole between two adjacent links of the adjustment chain, and the threaded rod can be inserted into the insertion hole. Example

[0017] A pipe welding butt support device, when extending and welding the ends of two pipes, the ends of the two pipes are respectively placed on an upper support frame, the ports of the two pipes are placed close together, the adjusting chain is rotated, the jack between two adjacent chain links on the adjusting chain is inserted into a threaded rod, and a locking nut is tightened on the threaded rod. The adjusting chain will press the upper part of the pipe end to prevent the tail of the pipe from tilting, thereby ensuring that the ports between the two pipes are aligned, and the ports of the two pipes are welded together by welding to ensure the quality of the pipe welding.
