In addition, a bad welding position has a great impact on welding quality, and very high welding level requirements are also placed on welders.

[0004] Therefore, we propose a pipeline welding auxiliary device to solve the above problems. Utility Model Content

[0025] See also Figure 1-2 , the utility model provides a technical solution of a pipeline welding auxiliary device:

[0026] Embodiment 1:

[0027] according to Figure 1 and Figure 2 As shown, it includes a support base 11, a right support clamp 1, a left support clamp 15 and two sets of drive components. Through holes are respectively opened at the four corners of the support base 11, and adjusting feet are arranged in the through holes. The adjusting feet include threaded feet 8 and two adjusting nuts 7. The upper ends of the threaded feet 8 pass through the through holes, and the two adjusting nuts 7 are respectively threadedly connected to the threaded feet 8. The two adjusting nuts 7 are respectively located on the upper surface and the lower surface of the support base 11. By rotating the adjusting nuts 7, the height of the threaded feet 8 can be adjusted. On the one hand, it can ensure that the pipeline material reaches a suitable height for the welder to weld. On the other hand, when the ground elevation is inconsistent, adjusting the threaded feet 8 can ensure that the support base 11 is in a horizontal state.

[0028] A fixing seat 16 is fixedly installed on the top of the support seat 11 , and a hinge shaft 10 is installed in the fixing seat 16 . The fixing seat 16 is extended from the front and rear ends of the hinge shaft 10 , and cotter pins 9 are respectively arranged at the front and rear ends of the hinge shaft 10 .

[0029] The bottom ends of the left support clamp 15 and the right support clamp 1 are respectively hinged to the hinge shaft 10, so that the left support clamp 15 and the right support clamp 1 can be flipped to adjust the angle between the left support clamp 15 and the right support clamp 1.

[0030] Two groups of detachable ball sleeves 12 are installed on the upper surfaces of the left support clamp 15 and the right support clamp 1. The specific disassembly method is: two groups of mounting holes are opened on the left support clamp 15 and the right support clamp 1. The lower section of the ball sleeve 12 passes through the mounting holes and is threadedly connected with the fixing nut 13. By setting the fixing nut 13, the ball sleeve 12 is easy to disassemble, so that the ball sleeve 12 can be replaced after it is damaged. A universal ball 14 is installed in the top groove of the ball sleeve 12. By setting two groups of universal balls 14 on the left support clamp 15 and the right support clamp 1, it can be ensured that the pipeline can roll and move in any direction, which is convenient for construction personnel to construct. The pipeline can be rotated to a better welding position to ensure the welding quality of the welder.

[0031] The lower surfaces of the left support clamp 15 and the right support clamp 1 are respectively mounted with hinge seats 2 , and the upper surface of the support seat 11 is mounted with another two hinge seats 2 .

[0032] The two groups of driving components are respectively arranged below the left support clamp 15 and the right support clamp 1, and the driving components include a bidirectional threaded barrel 5, an upper threaded rod 4 and a lower threaded rod 6. The thread directions of the upper threaded rod 4 and the lower threaded rod 6 are opposite. The upper threaded rod 4 and the lower threaded rod 6 are threadedly connected to the upper and lower ends of the bidirectional threaded barrel 5 respectively. The opposite ends of the upper threaded rod 4 and the lower threaded rod 6 are respectively hinged to the upper and lower hinge seats 2 through the pin shaft 3. By rotating the bidirectional threaded barrel 5, the threaded rod and the lower threaded rod 6 are moved away from or close to each other, and the angle between the left support clamp 15 and the right support clamp 1 is adjusted to facilitate supporting pipes of different diameters.

[0033] During specific use, the utility model is a pipeline welding auxiliary device. First, the bidirectional threaded barrels 5 on both sides are rotated. During the rotation of the bidirectional threaded barrels 5, the upper threaded rods 4 and the lower threaded rods 6 are moved away from or close to each other, and the angle between the left support clamp 15 and the right support clamp 1 is adjusted. Then, the pipeline is hung between the left support clamp 15 and the right support clamp 1. Finally, during the welding process, the workers can roll the pipeline between the left support clamp 15 and the right support clamp 1 as needed.

[0034] Embodiment 2:

[0035] Based on the first embodiment, the difference is as follows: the driving component is a hydraulic rod or an electric push rod.
