Description

Technical Field

[0001] The utility model relates to the field of trial fixing brackets, in particular to a fixing bracket for pipeline welder training and examination. Background Art

[0002] Pipeline welding refers to a process of connecting metal pipes to pipes or other metals by heating, pressurizing, etc. Pipeline welding is an important step in pipeline installation, and its welding quality has an important impact on the overall installation quality of the pipeline. Factors affecting pipeline welding quality include welding process and method, welder skill level, welding environment, welding equipment and welding materials, among which welder welding skill level has an important impact on pipeline welding quality. In order to ensure welder welding skill level, it is necessary to conduct skill training for welders regularly to maintain their skill level. In order to conduct skill training and assessment for welders and maintain their ability to meet pipeline welding skill level requirements under various conditions, a fixed bracket that can meet various pipeline welding methods is necessary.

[0003] Usually the fixed bracket includes a rotatable fixed barrel, which is used to load the pipe. Bolts for fixing the pipe are provided on one side of the fixed barrel. When the fixed barrel is laid flat, the fixed barrel is the main supporting point of the pipe. When the fixed barrel is tilted or set vertically, the pipe gradually loses the support of the fixed barrel, causing the pipe support to gradually change from the fixed barrel to the clamping of the bolts. Since the pipe is heavy and the clamping force of the bolts remains unchanged, the bolts will gradually lose their clamping force as the fixed barrel rotates to a vertical state, and finally the pipe slides toward the fixed barrel, resulting in insufficient exposed area of ​​a shorter pipe when the fixed barrel is placed, causing difficulties in welding and affecting the test operation of the candidates.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the fixed barrel is tilted or set vertically, the pushing screw is screwed into the pushing groove, and the pushing screw pushes the movable support plate to move. The space accommodating the cavity gradually becomes smaller under the push of the movable support plate. As the fixed barrel rotates to a vertical state, the movable support plate provides support for the pipe accommodating the cavity, and cooperates with the first fixing bolt to exert a constant clamping force on the pipe. Therefore, when a shorter pipe is placed in the fixed barrel, the push out of the movable support plate can still allow the pipe to maintain a certain exposed area, which is convenient for the examinee to operate the test.

A locking bolt 8 is threadedly connected to the locking hole 7, and the inserted end of the locking bolt 8 conflicts with the lifting rod 6.

[0024] When the height of the fixed barrel 11 needs to be adjusted, the lifting rod 6 is pulled upward, and the lifting rod 6 is lifted and lowered along the lifting cavity 5. The locking bolt 8 is screwed into the locking hole 7 so that the inserted end of the locking bolt 8 contacts the lifting rod 6, thereby fixing the position of the lifting rod 6 and raising the position of the fixed barrel 11.

[0025] Fixed plates 9 are provided on both sides of the lifting rod 6 , a rotating rod 10 is hinged on one side of the fixed plate 9 , and the rotating rod 10 is connected to the fixed barrel 11 .
