[0020] The embodiments of the present application are described below in detail with reference to the drawings, wherein the same or similar components are denoted by the same or similar reference numerals, and therefore the repeated description is omitted. The embodiments described below by reference to the drawings are exemplary, and are intended to explain the present application, and cannot be understood as a limitation of the present application. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "upper surface" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or component must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0021] Please refer to Figures 1-7 The present application provides an embodiment: a pipe joint row welding tool, comprising a bottom plate 1, one side of the bottom plate 1 is provided with a first support table 10, and the other side of the bottom plate 1 is provided with a second support table 13; the first support table 10 and the second support table 13 are both provided with a moving frame 3, the opposite faces of the first support table 10 and the second support table 13 are both provided with a support 11, and the support 11 is further provided with a lifting frame 2; a driving rod 4 is provided and passes through the support 11 and is connected with the moving frame 3, so that the driving rod 4 drives the moving frame 3 to move; the moving frame 3 comprises a support part 30, and the support part 30 is further provided with a pressing ring 31, and the pressing ring 31 is movably connected with the support part 30.

[0022] As described above, when the pipe is placed on the support part 30, the pipe is fixed on the support part 30 by the pressing ring 31, at this time, the moving frame 3 on the two support tables can be used to fix the two pipes and also complete the initial centering of the pipes; with the opposite movement of the driving rod 4 and the moving frame 3, the butt joint of the two pipes is completed, and after the butt joint, the lifting frame 2 is used to fine-tune the pipes to improve the centering effect of the two pipes. Based on this, the device uses the moving frame to tightly hold the pipe, so that the overall length of the device does not need to be greater than the length of the pipe, and after the pipe is tightly held, the lifting frame can be used to fine-tune the pipe to avoid the misalignment of the butt joint of the two pipes. In addition, the bottom plate 1 can be fixed to the ground by expansion bolts.

[0023] Specifically, the lifting frame 2 is further provided with a screw rod 20, and the screw rod 20 is threadedly connected with the rotating wheel 6; one end of the screw rod 20 is inserted into the through hole 14 provided on the support 11, so that the rotating wheel 6 is attached to the upper surface of the support 11, and the rotating wheel 6 is rotated on the support 11, so as to drive the lifting frame 2 to move upward or downward. Therefore, the rotation of the rotating wheel 6 can drive the lifting frame 2 to move up and down, so as to center the two pipes.

[0024] Further, the screw rod 20 is further provided with a sliding groove 21, and the inner wall surface of the through hole 14 is further provided with a guide block 15 matched with the sliding groove 21. Therefore, the rotation of the rotating wheel 6 can be avoided from driving the lifting frame 2 to rotate.

[0025] Meanwhile, the lower end of the support part 30 is connected with the waist-shaped groove 12 provided on the first support table 10 through the sliding block 33. Therefore, the sliding block 33 and the waist-shaped groove 12 are matched, so as to ensure the directional sliding of the moving frame 3, and further ensure the centering effect of the two pipes.

[0026] Further, the sliding block 33 is further provided with a connecting rod 34, and the connecting rod 34 is connected with the nut 5 after penetrating through the waist-shaped groove 12. Therefore, the moving frame 3 can be further limited on the support table through the nut 5, so as to avoid the inclination of the pipe after being installed on the moving frame 3, and further reduce the adverse effect of the pipe pressure on the driving rod 4, i.e. the problem that the driving rod 4 is bent or the resistance of the driving rod 4 is too large during rotation.

[0027] Specifically, the driving rod 4 is connected with the screw rod seat 32 provided on the support part 30, and the driving rod 4 is rotated in the screw rod seat 32, so as to drive the moving frame 3 to move.

[0028] In summary, the device can center the pipes while the overall length of the device is small. In addition, the bolt is connected with the support part 30 after penetrating through the compression ring 31, so as to fix the pipes and facilitate the taking and placing of the pipes. Especially, when the pipes are spot-welded, the loosened bolt can rotate in the two moving frames 3, so as to full-weld the butt joint.

[0029] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
