[0019] Refer to Figures 1-5 A kind of heat supply pipeline welding auxiliary support device, its composition includes two V-shaped chucks 1, two described V-shaped chucks are clamped with wedge-shaped plate 2 and are fixed by bolt between them;

[0020] Described wedge-shaped plate both sides have strip-shaped hole 9, and described wedge-shaped plate middle part has opening 10;

[0021] Two V-shaped chucks are clamped with wedge-shaped plate in the middle of opposite buckle, and the inclination angle of the upper and lower surfaces of wedge-shaped plate is consistent with the inclination angle of the bottom surface of V-shaped chuck, after being fixed by bolt, the common clamping of first pipeline 6 and second pipeline 7 can be realized, so that the concentricity of first pipeline and second pipeline can be guaranteed after being clamped, so that it is convenient for welding;

[0022] Meanwhile, wedge-shaped plate middle part has opening, and the setting of this opening can leave welding space in the welding process;

[0023] Described V-shaped chuck includes I-shaped adjusting plate 5 and four V-shaped clamping plates 3, and every two of four described V-shaped clamping plates are a row, and two V-shaped clamping plates in the same row are fixed by U-shaped connecting plate 4, and described I-shaped adjusting plate is fixed by bolt with two described U-shaped connecting plates respectively;

[0024] U-shaped connecting plate is welded with V-shaped clamping plate, by dividing V-shaped chuck into four V-shaped clamping plates, into two rows, and the V-shaped clamping plate of each row is two;

[0025] The I-shaped adjusting plate is welded by two vertical plates and a horizontal plate, and a plurality of adjusting holes 8 are formed in each vertical plate.

[0026] Working principle: when the first pipeline and the second pipeline need to be butt welded, first support the two pipelines, the support method is the prior art, which will not be described in detail, then remove the bolt connecting the two V-shaped clamps, buckle the upper V-shaped clamp above the pipeline, buckle the lower V-shaped clamp below the pipeline, insert the wedge-shaped block between the two V-shaped clamps, pass the bolt through the strip-shaped hole of the wedge-shaped plate, the upper V-shaped clamp, and then threadedly connect the nut, and fasten, thereby realizing the simultaneous clamping of the first pipeline and the second pipeline, and ensuring the concentricity and stability during butt welding of the two pipelines.

[0027] When encountering a larger pipeline diameter, the device can be adjusted, referring to Figures 6-7 , remove the bolt connecting the two V-shaped clamps, then remove the bolts between the first row of U-shaped connecting plates of the upper V-shaped clamp and the I-shaped adjusting plate, and the second row of U-shaped connecting plates and the I-shaped adjusting plate, then select different connecting hole bolts to reinstall and fasten, thereby adjusting the position between the two rows of V-shaped clamps, after adjustment, adjust the position of the two rows of V-shaped clamps of the lower V-shaped clamp in the same way as the adjustment of the upper V-shaped clamp, after adjustment, buckle the upper V-shaped clamp above the pipeline, buckle the lower V-shaped clamp below the pipeline, insert the wedge-shaped block between the two V-shaped clamps, pass the bolt through the strip-shaped hole of the wedge-shaped plate, the lower V-shaped clamp, and the upper V-shaped clamp, and then threadedly connect the nut, fasten the nut to realize the connection of the first pipeline and the second pipeline, at this time the upper and lower surfaces of the wedge-shaped plate are not in contact with the surface of the V-shaped clamp, then knock the wedge-shaped plate with a hammer to gradually insert it inward until the wedge-shaped plate is tightly inserted between the two V-shaped clamps and stops, at this time the stable support of the two V-shaped clamps can be realized.
