[0006] The second support assembly includes a second support seat and an adjusting sleeve, and a second raceway is arranged on the side surface of the second support seat facing the rolling assembly; the adjusting sleeve is sleeved outside the second support seat, and the two are screwed together;

[0007] The rolling assembly is composed of a rolling cage and a plurality of balls. The balls protrude from the two end faces of the rolling cage and extend into the first raceway and the second raceway respectively. The two end faces of the rolling cage do not contact the first support seat and the second support seat.

[0008] In the above-mentioned auxiliary tool for vertical pipe welding, the first support assembly further includes a first flange and a plurality of clamping blocks. A plurality of first clamping grooves are arranged on the first flange, and a plurality of second clamping grooves are arranged on the upper side surface of the first support seat. The clamping blocks are simultaneously located in the first clamping grooves and the second clamping grooves corresponding in position.

[0009] In the above-mentioned auxiliary tool for vertical pipe welding, the second clamping groove extends to the outer wall of the first support seat, so as to open on the outer side wall of the first support seat, and the first clamping groove also extends to the outside of the first support seat.

[0010] In the above-mentioned auxiliary tool for vertical pipe welding, rubber pads are bonded to the side surfaces of the first support seat and the first flange that contact the pipe to be supported.

[0027] As Figures 1-3 shown, the vertical pipe welding auxiliary tool includes a second support assembly 1, a rolling assembly 2 and a first support assembly 3; the rolling assembly 2 is arranged between the second support assembly 1 and the first support assembly 3, so that the first support assembly 3 can rotate relative to the second support assembly 1. The rolling assembly 2 is composed of a rolling cage 21 and a plurality of balls 22, and the balls 22 protrude out of the two end faces of the rolling cage 21. The rolling cage 21 is formed by butting two plate members, and a cavity for accommodating the balls 22 is formed inside. This is the prior art, so it is not shown in the figure.

[0028] The first support assembly 3 contacts the pipeline and rotates synchronously with the pipeline during the welding process. The first support assembly 3 includes a first support base 31, and a first raceway 32 is arranged on the side surface of the first support base 31 facing the rolling assembly 2. The first raceway 32 is circular and cooperates with the balls 22 to limit the rolling of the balls 22 in the first raceway 32.

[0029] The first support base 31 contacts the pipeline to support the pipeline; however, when the outer diameter of the pipeline is greater than the outer diameter of the first support base 31, the first support base 31 cannot form a stable support for the pipeline. At this time, the first flange 33 can be applied. The outer diameter of the first flange 33 is greater than that of the first support base 31. The first flange 33 is arranged between the pipeline and the first support base 31 to achieve stable support for the pipeline.

[0030] Furthermore, a plurality of first card slots 35 are arranged on the first flange 33, and a plurality of second card slots 34 are arranged on the upper side surface of the first support base 31. By putting the clamping blocks 36 into the first card slots 35 and the second card slots 34 at corresponding positions at the same time, the rotation of the first flange 33 and the first support base 31 can be locked, and the two rotate synchronously. The structure of the clamping block 36 is adapted to the inner cavity shapes of the first card slot 35 and the second card slot 34.

[0031] Preferably, the second card slot 34 extends to the outer wall of the first support base 31, so as to open on the outer side wall of the first support base 31, and the first card slot 35 also extends to the outside of the first support base 31; in this way, the operation of inserting or removing the clamping block 36 can be performed on the side surface of the first support base 31.

[0032] The first support assembly 3 supports on the lower side of the pipeline and rotates synchronously with the pipeline; a rubber pad can be arranged on the side surface where the first support base 31 and the first flange 33 are in contact with the end surface of the pipeline to prevent the pipeline from slipping, and at the same time, soft contact between the pipeline and the support surface can also be achieved. The rubber pad can be adhered to the first support base 31 and the first flange 33.

[0033] The second support assembly 1 includes a second support base 15. A second raceway 17 is arranged on the upper side surface of the second support base 15. The second raceway 17 is also annular. When in use, the rolling assembly 2 is placed on the second support base 15, and the balls 22 are located in the second raceway 17; both end faces of the rolling cage 21 are not in contact with the first support base 31 and the second support base 15 to avoid increasing the frictional resistance.

[0034] In order to facilitate the withdrawal of this auxiliary tool after the pipeline is welded, an adjusting sleeve 11 is sleeved on the outside of the second support base 15. Threads are processed on the inner wall of the adjusting sleeve 11 and the outer wall of the second support base 15, and the two are screwed together. After the pipeline is welded, the second support base 15 and the adjusting sleeve 11 are rotated relative to each other, and the overall axial length of the two can be shortened, and the auxiliary tool can be easily separated from the pipeline.

[0035] A holding boss 18 is arranged on the outer side wall of the end of the second support base 15 protruding out of the adjusting sleeve 11. The outer side wall of the holding boss 18 is uneven, which is convenient for operation.

[0036] When the outer diameter of the pipeline is relatively large, the contact area between the second support assembly 1 and a support surface such as the ground is increased, and the overall support stability can be improved. Therefore, the second support assembly 1 can also be provided with an auxiliary base 12. A clamping table 14 is arranged on the upper side surface of the auxiliary base 12. A third card slot 13 is arranged on the outer wall of the adjusting sleeve 11. The clamping table 14 cooperates with the third card slot 13 to position the adjusting sleeve 11.

[0037] Furthermore, an annular connecting table 16 is arranged on the outer side of the clamping table 14, which can better position and support the adjusting sleeve 11.

[0038] The basic principle, main features and advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
