Abstract
Description
[Technical field]
[0001] The utility model belongs to the technical field of aerial butt welding devices for bent pipes and straight pipes, and in particular relates to a centering welding auxiliary device for bent pipes. [Background technology]
[0002] In many construction sites, production workshops and other places, you will encounter the working scene of butt welding between bent pipes and straight pipes. Usually, the balance point is found manually and the bent pipe is held by hand before welding. This method of welding by manual balance has the following disadvantages:
[0003] First, when a small elbow is butt-welded with a straight pipe, one hand is required to hold the elbow and the other hand is required to weld. This not only increases the labor intensity of the workers, but also the welding quality is often not very good. In addition, when a large elbow is butt-welded with a straight pipe, multiple workers are required to assist in welding, which results in low production efficiency.
[0004] Second, aerial welding requires setting up a platform or using scaffolding for welding, which is time-consuming and labor-intensive, with high labor intensity for workers and low welding efficiency.
[0005] In order to overcome the above technical problems, after a long period of observation and research, the applicant discloses a bending pipe centering welding auxiliary device. [Contents of the utility model]

[0009] Preferably, the threaded hole 13 and the locking screw 12 are connected by threads.
[0010] Preferably, the handle 6 is an L-shaped structure.
[0011] Compared with the prior art, the utility model provides a bending pipe centering welding auxiliary device, which has the following beneficial effects:
[0012] The lifting ring 8 is suspended by a bracket, and then the elbow 14 is clamped, and the screw rod 5 is rotated by the handle 6 to change the position of the welding port of the elbow 14. No multiple people are required to assist, which reduces the labor intensity of workers, especially when welding large pipelines, and saves time and effort, thereby improving the production efficiency of workers in welding.
