Description

Technical Field

[0001] The utility model belongs to the field of pipeline welding, and in particular relates to a pipeline welding jig. Background Art

[0002] During the pipeline installation construction process undertaken by our unit, a large number of pipelines need to be welded.

[0003] During the welding process, a homemade jig is needed to support the pipes. The jig we initially made was composed of an angle steel and a support foot installed at the bottom of the angle steel. This jig has a simple structure and can support two pipes, but it still has certain shortcomings during use:

[0004] 1. Lack of fixation of the two pipes, unexpected shaking during welding, easily affecting the welding quality;

[0005] 2. Two pipes are placed on the same angle steel. After welding an area of ​​the two pipes, the two pipes need to be flipped. Flipping the pipes is not only laborious but also affects the welding efficiency.

[0006] Therefore, we propose a pipeline welding jig to solve the above problems. Utility Model Content

[0007] Aiming at the problem that our self-made jig lacks the ability to fix the pipeline and that two pipelines need to be turned over after welding an area, the utility model provides a pipeline welding jig.

[0008] The utility model solves the technical problem by adopting a solution: a pipeline welding jig, comprising a connection assembly, two angle steels and two sets of parallel supporting units, wherein the supporting units comprise a base and a parallel top seat, and a supporting arm is fixedly connected between the base and the top seat;

[0009] Two angle steels are fixedly connected to the tops of the two top seats respectively;

[0010] The connecting component is installed between the two supporting arms and can adjust the distance between the two supporting arms.

[0011] Preferably, the connecting assembly includes a threaded rod and a fixing nut, the fixing nut is clamped in the support arm on either side, the threaded rod is threadedly connected to the fixing nut, the optical axis end of the threaded rod is sleeved with a bearing, and the bearing is installed on the support arm on the other side.

[0012] Preferably, a rotating disk is installed on the threaded end of the threaded rod.

[0013] Preferably, a plurality of mounting holes are provided on the base corresponding to the fixing nut.

[0014] Preferably, two strip holes are provided on the top seat, and the two strip holes are respectively located at the front and rear sides of the angle steel.

[0015] Preferably, two U-shaped bolts are further included, and the two U-shaped bolts are respectively arranged corresponding to the two top seats, and the two sections of threads of the U-shaped bolts pass through the two strip holes respectively.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model places two pipes in two angle steels respectively, and fixes the pipes one by one with U-bolts to ensure the stability of the two pipes during welding. By rotating the threaded rod forward, the pipe on the right is moved toward the pipe on the left, and then the welding ends of the two pipes are aligned to facilitate welding of the two pipes. The two angle steels are used to support the two pipes respectively, so that a gap is left between the two angle steels to facilitate comprehensive welding of the pipes without turning the pipes over.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] See also Figure 1-2 The utility model provides a technical solution for a pipeline welding jig:

[0023] Embodiment 1:

[0024] according to Figure 1 and Figure 2 As shown, it includes a connecting component, two angle steels 21 and two groups of parallel supporting units. The supporting unit includes a base 11 and a parallel top seat 13. The base 11 and the top seat 13 are respectively made by cutting steel plates. A supporting arm 12 is fixedly connected between the base 11 and the top seat 13, and the supporting arm 12 is made of a square tube.

[0025] Two angle steels 21 are fixedly connected to the tops of the two top seats 13 , respectively, and the two pipes are supported by the two angle steels 21 . The top seats 13 are provided with two strip holes 14 , which are respectively located at the front and rear sides of the angle steels 21 .

[0026] It also includes two U-bolts 22, which are respectively arranged corresponding to the two top seats 13. The two threads of the U-bolts 22 pass through the two strip holes 14 respectively. The pipes are fixed by the U-bolts 22 to ensure the stability of the two pipes during the welding process.

[0027] The connecting assembly is arranged between the two support arms 12, and the connecting assembly includes a threaded rod 31 and a fixing nut 32. The fixing nut 32 is clamped in the support arm 12 on either side. The threaded rod 31 is threadedly connected with the fixing nut 32. The optical axis end of the threaded rod 31 is sleeved with a bearing 34, and the bearing 34 is installed on the support arm 12 on the other side. By rotating the threaded rod 31 forward, the pipe on the right side can be moved toward the pipe on the left side. The distance between the two support arms 12 is adjusted to align the welding ends of the two pipes to facilitate welding of the two pipes. A rotating disk 33 is installed at the threaded end of the threaded rod 31, so that the user can use the rotating disk 33 to drive the threaded rod 31 to rotate.

[0028] A plurality of mounting holes are provided on the base 11 corresponding to the fixing nuts 32 , so that fixing parts can be passed through the mounting holes to fix the base 11 on the left side, so that the base 11 on the right side can be moved.

[0029] When used specifically, the utility model is a pipe welding jig. First, the fixing piece is passed through the mounting hole to fix the base 11 on the left side so that the base 11 on the right side can be moved. Then, two pipes are placed in two angle steels 21 respectively. During the placement process, the butt ends of the pipes protrude from the angle steels 21.

[0030] After the pipelines are placed, the U-bolts 22 are used to fix the pipelines one by one, and then the rotating disk 33 is rotated forward to drive the threaded rod 31 to rotate, so that the pipeline on the right moves toward the pipeline on the left, and then the welding ends of the two pipelines are aligned, and finally the two pipelines are welded using a welding tool.

[0031] Embodiment 2:

[0032] Based on the first embodiment, the difference is as follows: in order to further facilitate the movement of the unfixed base 11 on the right side, a ball or roller can be installed at the bottom of the base 11.
