[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] Reference Figures 1 to 7As shown, a pipeline welding tool of an embodiment of the utility model is used for welding a first pipeline 100 and a second pipeline 200, comprising: a bottom plate 300, a first support block 400, a first rotating mechanism 500, a second support block 600, and a second rotating mechanism 700. The first supporting block 400 is used to support the first pipeline 100. The first supporting block 400 can be moved forward and backward and adjusted at the upper end of the bottom plate 300, so the first supporting block 400 can adjust the position of the first pipeline 100 in the front and rear direction. The first rotating mechanism 500 is connected to the bottom plate 300, and the first rotating mechanism 500 is used to drive the first pipeline 100 to rotate; the first rotating mechanism 500 is against one end of the first pipeline 100 away from the first supporting block 400, and one end of the first pipeline 100 is supported by the first supporting block 400, and the other end is supported by the first rotating mechanism 500. Since the adjustment range of the first supporting block 400 is not large, when the first supporting block 400 moves, the end of the first pipeline 100 away from the first supporting block 400 will not be separated from the first rotating mechanism 500. The second support block 600 is used to support the second pipe 200, and the second support block 600 is arranged on the upper end of the bottom plate 300 so as to be movable and adjustable left and right. The second support block 600 can adjust the position of the second pipe 200 in the left and right directions. The second rotating mechanism 700 is connected to the bottom plate 300, and the second rotating mechanism 700 is used to drive the second pipe 200 to rotate. By adjusting the first support block 400 and the second support block 600 respectively, the position of the first pipe 100 and the second pipe 200 can be adjusted to facilitate welding. It is foreseeable that the first rotating mechanism 500 and the second rotating mechanism 700 should drive the first pipe 100 and the second pipe 200 to rotate synchronously. The first pipe 100 and the second pipe 200 rotate so as to facilitate welding around the gap between the first pipe 100 and the second pipe 200.

[0040] Reference Figure 3 As shown, it can be understood that the first support block 400 and the second support block 600 are respectively provided with a first arc-shaped groove 410 and a second arc-shaped groove 610 at their upper ends, and the shapes of the first arc-shaped groove 410 and the second arc-shaped groove 610 are respectively matched with the shapes of the first pipe 100 and the second pipe 200. The lower end of the first pipe 100 is embedded in the first arc-shaped groove 410, and the first arc-shaped groove 410 is provided to increase the contact area with the first pipe 100, so that the first pipe 100 is not easy to shake after being supported by the first support block 400, which is conducive to improving the stability of the first pipe 100, and the lower end of the second pipe 200 is embedded in the second arc-shaped groove 610, and the second arc-shaped groove 610 is provided to increase the contact area with the second pipe 200, so that the second pipe 200 is not easy to shake after being supported by the second support block 600, which is conducive to improving the stability of the second pipe 200.

[0041] Reference Figure 1 and Figure 3As shown, it can be understood that the rotation axes of the first arc groove 410 and the second arc groove 610 both extend in the left-right direction. Since the first pipe 100 and the second pipe 200 need to be coaxially welded, the first arc groove 410 and the second arc groove 610 should be approximately coaxially arranged.

[0042] Reference Figures 3 to 5 As shown, it can be understood that the first rotating mechanism 500 includes a first active roller 510, a first driven roller 520 and a first motor 530. The first active roller 510 and the first driven roller 520 are both rotatably mounted above the bottom plate 300. The first active roller 510 and the first driven roller 520 are arranged in parallel, and the rotation axes of the first active roller 510 and the first driven roller 520 extend in the left-right direction. The first active roller 510 and the first driven roller 520 are simultaneously against the first pipe 100, and the distance between the outer wall of the first active roller 510 and the outer wall of the first driven roller 520 is smaller than the diameter of the first pipe 100, so as to support the first pipe 100 at the same time. The first motor 530 is connected to the first active roller 510 through a belt drive, and the first active roller 510 can drive the first pipe 100 to rotate when rotating. It is foreseeable that the outer wall of the first active roller 510 and the outer wall of the first driven roller 520 are both provided with a rubber layer to increase the friction force and prevent the first active roller 510 from slipping when driving the first pipeline 100 to rotate.

[0043] Reference Figures 3 to 5 As shown, it can be understood that the second rotating mechanism 700 includes a second active roller 710, a second driven roller 720, and a second motor 730. The second active roller 710 and the second driven roller 720 are both rotatably mounted above the bottom plate 300. The second active roller 710 and the second driven roller 720 are arranged in parallel, and the rotation axes of the second active roller 710 and the second driven roller 720 extend in the left-right direction. The second active roller 710 and the second driven roller 720 are simultaneously against the second pipe 200, and the distance between the outer wall of the second active roller 710 and the outer wall of the second driven roller 720 is less than the diameter of the second pipe 200, so as to support the second pipe 200 at the same time. The second motor 730 is connected to the second active roller 710 through a belt drive, and the second active roller 710 can drive the second pipe 200 to rotate when it rotates. It can be foreseen that the outer wall of the second active roller 710 and the outer wall of the second driven roller 720 are both provided with a rubber layer to increase the friction force and prevent the second active roller 710 from slipping when the second active roller 710 drives the second pipe 200 to rotate.

[0044] Reference Figure 1As shown, it can be understood that electromagnets are provided in the first support block 400 and the second support block 600. During welding, in order to prevent the first pipe 100 and the second pipe 200 from shifting, the electromagnet is energized, and the electromagnet generates attraction to the first pipe 100 and the second pipe 200, so that the first pipe 100 is fixed on the first support block 400, and the second pipe 200 is fixed on the second support block 600, which effectively improves the quality of welding. When rotating the first pipe 100 and the second pipe 200, the electromagnet is de-energized so that the first motor 530 and the second motor 730 respectively drive the first pipe 100 and the second pipe 200 to rotate.

[0045] Reference Figures 3 to 7 As shown, it can be understood that a slider 420 is provided at the lower end of the first support block 400, and a first slide groove 310 extending in the front-to-back direction is provided on the bottom plate 300. The slider 420 is located in the first slide groove 310, and the size of the slider 420 matches the size of the first slide groove 310. The slider 420 can move forward and backward along the first slide groove 310, and the first slide groove 310 plays a role of limiting and guiding the slider 420. A first screw 320 extending in the front-to-back direction is rotatably installed on the top of the bottom plate 300, and two first mounting plates are welded in parallel at the upper end of the bottom plate 300. The two ends of the first screw 320 are rotatably installed on the first mounting plates respectively. Two shaft sleeves are also connected to the first screw 320, and the shaft sleeves are respectively against the corresponding first mounting plates to limit the axial position of the first screw 320. The first screw 320 passes through the slider 420 and is threadedly connected to the slider 420. When the first screw 320 rotates, it can drive the slider 420 to move forward and backward along the first slide groove 310. Thereby, the front-rear position of the first pipe 100 at the upper end of the first supporting block 400 is adjusted.

[0046] Reference Figure 3 As shown, it is understandable that the cross section of at least one end of the first screw rod 320 is a regular hexagon, so as to be convenient for rotation using a wrench. It is foreseeable that a hand wheel may also be provided at the end of the first screw rod 320 to facilitate rotation of the first screw rod 320.

[0047] Reference Figure 6 and Figure 7As shown, it can be understood that the first support block 400 is symmetrically provided with four first threaded holes 430 extending in the vertical direction, and the four first threaded holes 430 are symmetrically distributed along the first arc-shaped groove 410. A height adjustment bolt 440 is threadedly connected in the first threaded hole 430, and four positioning blind holes 421 are provided at the upper end of the slider 420 corresponding to the four height adjustment bolts 440. The lower end of the height adjustment bolt 440 extends out of the first threaded hole 430 and extends into the positioning blind hole 421 provided at the upper end of the slider 420, and the bottom end of the height adjustment bolt 440 abuts against the bottom wall of the positioning blind hole 421, and the length of the height adjustment bolt 440 is greater than the sum of the length of the first threaded hole 430 and the length of the positioning blind hole 421. Rotating the height adjustment bolt 440 can change the length of the lower end of the height adjustment bolt 440 extending out of the first threaded hole 430, thereby changing the height of the first support block 400, and by rotating the height adjustment bolt 440, the height of the first pipe 100 can be adjusted so that the first pipe 100 and the second pipe 200 can be aligned.

[0048] Reference Figures 1 to 3 As shown, it can be understood that the bottom plate 300 is provided with a second slide groove 330 extending in the left-right direction, the lower end of the second support block 600 extends into the second slide groove 330, and the second support block 600 can move in the left-right direction along the second slide groove 330. A second screw rod 340 extending in the left-right direction is rotatably mounted on the top of the bottom plate 300, a second mounting plate is welded on the top of the bottom plate 300, and the second screw rod 340 is rotatably mounted on the second mounting plate. The second screw rod 340 passes through the second support block 600 and is threadedly connected with the second support block 600. The second screw rod 340 is also provided with a boss that abuts against the second mounting plate to limit the axial position of the second screw rod 340. When the second screw rod 340 rotates, it can drive the second support block 600 to move forward and backward along the second slide groove 330. Thereby, the function of adjusting the left-right position of the second pipe 200 at the upper end of the second support block 600 is realized. It can be foreseen that the cross section of the end of the second screw rod 340 is also a regular hexagon for easy operation.

[0049] Usage steps: hoist the first pipe 100 onto the first support block 400 and the first rotating mechanism 500, hoist the second pipe 200 onto the second support block 600 and the second rotating mechanism 700, energize the electromagnet, the electromagnet generates attraction to the first pipe 100 and the second pipe 200, fix the first pipe 100 on the first support block 400, and fix the second pipe 200 on the second support block 600. The first screw rod 320 is rotated to adjust the front and rear position of the first pipe 100 close to one end of the second pipe 200, the height adjustment bolt 440 is rotated to adjust the height of the first pipe 100 close to one end of the second pipe 200, the second screw rod 340 is rotated, and the second support block 600 drives the second pipe 200 to approach the first pipe 100, so that the distance between the second pipe 200 and the first pipe 100 does not exceed 2 mm, and the upward part between the first pipe 100 and the second pipe 200 is welded, and then the electromagnet is powered off, and the first motor 530 and the second motor 730 respectively drive the first pipe 100 and the second pipe 200 to rotate, and the unwelded part between the first pipe 100 and the second pipe 200 is rotated to face upward, and then the electromagnet is powered on, and the welding is continued until the gap between the first pipe 100 and the second pipe 200 is completely welded, and the electromagnet is powered off, and the welded first pipe 100 and the second pipe 200 are hoisted to the next process.

[0050] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
