Description

[0001] The utility model relates to the technical field of pipeline processing, in particular to a pipe section alignment tooling. Background Art

[0002] Metal pipelines are an important part of engineering facilities, and play the tasks of conveying media and transmitting information in construction projects. The routing of each metal pipeline is determined according to its function and the space it is in, and often has the characteristics of being intricate. During the construction process, metal pipelines are generally prefabricated in sections, and then, according to actual needs, multiple pipe sections are butt-welded in sequence to assemble into an entire pipeline.

[0003] During welding, it is necessary to fix the two butt-welded pipe sections. The existing fixing method is to use a temporarily built template, that is, welding plates are welded on the working platform for placing the pipe sections according to the pipe diameter, and the pipe sections are limited by abutting against the plates. This method cannot adjust the distance between the plates, so it cannot meet the fixing of pipe sections with different diameters. When changing the model, it is necessary to cut off the welding position of the plates and then weld them again, which is cumbersome and causes too much welding slag on the working platform and makes it uneven. In addition, the butt-weld is a circumferential weld. Since the pipe section is placed on the working platform, the bottom welding is blocked. When the pipe section needs to be flipped during the welding process, the lower weld is exposed, which is inconvenient to operate, reduces the butt joint efficiency, and is prone to welding quality problems.

Detailed implementation manners

[0026] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. For the convenience of description, words such as "upper", "lower", "left", and "right" hereinafter only indicate the same direction as the upper, lower, left, and right directions of the drawings themselves, and do not limit the structure.

[0027] As Figure 1 shown, a pipe segment assembly tool 10 provided in this embodiment includes a chassis 1, a support frame 2, an adjusting rod 3, and a pressing rod 4.

[0028] As Figure 1 、 Figure 2 shown, the chassis 1 includes a support 12 and three legs 11 obliquely connected to the bottom of the support 12. A sleeve 13 is provided on the support 12, the top of the sleeve 13 is rotatably connected to the first adjusting nut 15, a through hole 14 for the first screw 25 to pass through is provided in the sleeve 13, and the through hole 14 passes through the support 12. Two, three or four first grip bars 16 are provided on the outer circumferential surface of the first adjusting nut 15.

[0029] As Figure 1 、 Figure 3As shown in the figure, the support frame 2 includes a groove frame 21, a V-shaped frame 22, rollers 23, an L-shaped bracket 24, a first screw 25 and a second screw 26. The cross-section of the groove frame 21 is U-shaped, and its length is set according to actual needs. The bottom of the groove frame 21 is connected to the first screw 25, and the first screw 25 is connected to the first adjusting nut 15. Inside the groove frame 21, there is a V-shaped frame 22. The V-shaped frame 22 is a rod, and two or more are arranged at intervals in the length direction of the groove frame 21. A rotating shaft is connected between two adjacent rods, and the rollers 23 are rotatably arranged on the rotating shaft. Pipe sections for assembly are placed on the rollers 23, and the pipe sections for assembly are rotated manually to drive the rollers 23 to rotate adaptively. By rotating the first adjusting nut 15, the height of the groove frame 21 on the first screw 25 is adjusted, so as to adjust the height of the pipe sections placed on the V-shaped frame 22.

[0030] One end of the groove frame 21 is connected to one end of the L-shaped bracket 24, and the other end of the L-shaped bracket 24 rotatably arranges the second screw 26. According to the length of the groove frame 21, one first screw 25 or two or more first screws 25 are arranged at its bottom, as Figure 5 shown, the chassis 1 corresponds to the first screw 25 one by one. The L-shaped bracket 24 is arranged at the corresponding position on the groove frame 21.

[0031] As Figure 4 shown, the adjusting rod 3 includes a rod body 31, a second adjusting nut 32 and a third adjusting nut 33. The second adjusting nut 32 and the third adjusting nut 33 are respectively arranged at both ends of the rod body 31. The second screw 26 is horizontally threadedly connected to the second adjusting nut 32, and the pressing rod 4 is vertically threadedly connected to the third adjusting nut 33. The inside of the rod body 31 is hollow for the second screw 26 to extend into. When the second screw 26 is selected, the second adjusting nut 32 and the rod body 31 on it can be horizontally displaced. At this time, the adjusting rod 3 needs to be held by hand to prevent it from rotating together with the second screw 26. The L-shaped bracket 24 is fixedly connected or hinged to the groove frame 21. When hinged, the L-shaped bracket, the adjusting rod 3 and the pressing rod 4 can be turned down together to install or place the pipe sections in a more convenient way.

[0032] The pressing rod 4 includes a third screw 41 threadedly connected to the third adjusting nut 33 and a second grip 42 connected to the top of the third screw 41. The third screw 41 is arranged opposite to the V-shaped frame 22 for clamping the pipe section 5 (as Figure 5 shown).

[0033] As Figure 5 , Figure 6As shown in the figure, the butt joint of pipe sections includes the butt joint of bent pipes and straight pipes, and the length of the groove frame 21 is adapted to the length of the pipe sections to be butted. During use, each of the two pipe sections 5 for butt joint uses a pipe section alignment tooling 10. The pipe section 5 is hoisted onto the support frame 2 and contacts the roller 23. Select the first adjusting nut 15 to adjust the height of the support frame 2 so that the center lines of the two butted pipe sections are aligned. Then, adjust the second screw rod 26 and the third screw rod 41 respectively so that the third screw rod 41 clamps the upper surface of the pipe section 5. Weld at the weld seam. The circumferential weld can be directly welded without flipping. It is also possible to first remove the pressing rod 4, start the roller 23 to expose the weld seam on the other side of the pipe section, turn the unwelded surface of the pipe section to be processed into flat welding, and then repeat the above steps for flat welding operations, cycling until the assembly welding of the entire pipe section is finally completed.

[0034] The rotational connection of the first adjusting nut 15 on the sleeve 13 and the rotational connection of the second screw rod 26 on the L-shaped bracket 24 can both be achieved through bearings.

[0035] By adjusting the support frame 2 on the two pipe section alignment toolings 10 at different heights on the chassis 1, the center lines of the two pipe sections 5 of the variable-diameter pipes to be assembled are on the same horizontal plane, which is suitable for the alignment welding requirements of variable-diameter pipes.

[0036] The pipe section alignment tooling of the present utility model is applicable to the alignment welding of pipe sections with different diameters and weights. The alignment dimensions between various components are precisely adjustable. During the welding process, the pipe sections are firmly fixed, the welding operation height is adjustable, flat welding is achieved, the welding efficiency and welding quality are improved, and both the prefabrication of straight pipe sections and bent pipe sections can be adapted. The applicability of pipe section alignment welding is extremely high, ensuring the prefabrication efficiency and quality of pipe sections.
