Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, and in particular to an auxiliary tooling for pipeline alignment. Background Technology

[0002] In shipbuilding, flange connections or welding are typically used to connect pipelines. To ensure the quality of the connection, the ends of the two pipelines must be precisely aligned before construction. However, in actual construction, factors such as pipeline positioning deviations, pipe processing errors, and possible compression deformation during transportation often result in misalignment of the two pipelines at the connection point. This misalignment not only reduces installation quality but also significantly affects construction efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an auxiliary tooling for pipeline alignment, so as to facilitate the alignment of two pipelines.

[0004] The present invention provides a pipeline alignment auxiliary tooling, including a drive rod, one end of which is provided with a first U-shaped fork and a second U-shaped fork spaced side by side, both the first U-shaped fork and the second U-shaped fork forming an opening in a direction perpendicular to the length direction of the drive rod, and the openings facing the same direction; For the first and second pipelines that need to be aligned, the first U-shaped fork can be engaged on the first pipeline, and the second U-shaped fork can be engaged on the second pipeline.

[0005] Furthermore, the pipeline alignment auxiliary tooling also includes a U-shaped fork; The U-shaped fork is connected to one end of the drive rod. The U-shaped fork includes a first arm and a second arm that are arranged in parallel and spaced apart. Both the first arm and the second arm are parallel to the drive rod.

[0006] Furthermore, the first support arm is provided with a first limiting rod and a second limiting rod, which are arranged in parallel and spaced apart to form the first U-shaped fork head on the first support arm.

[0007] Furthermore, at least one of the first limiting rod and the second limiting rod is a first movable limiting rod; The installation position of the first movable limiting rod on the first support arm is adjustable along the length direction of the first support arm.

[0008] Furthermore, the first arm is provided with a plurality of first internal thread connection holes, which are arranged side by side at intervals along the length of the first arm. One end of the first movable limiting rod is provided with a first external threaded connection part, which can be adapted to be screwed into any of the first internal threaded connection holes.

[0009] Furthermore, the second support arm is provided with a third limiting rod and a fourth limiting rod, which are arranged in parallel and spaced apart to form the second U-shaped fork head on the second support arm.

[0010] Furthermore, at least one of the third limiting rod and the fourth limiting rod is a second movable limiting rod; The installation position of the second movable limiting rod on the second support arm is adjustable along the length direction of the second support arm.

[0011] Furthermore, the second arm is provided with a plurality of second internal threaded connection holes, which are arranged side by side at intervals along the length of the second arm; One end of the second movable limiting rod is provided with a second external threaded connection part, which can be adapted to be screwed into any of the second internal threaded connection holes.

[0012] Furthermore, both the first U-shaped fork and the second U-shaped fork are covered with a buffer sleeve.

[0013] Furthermore, the drive rod is fitted with an anti-slip rubber sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The pipeline alignment auxiliary tooling provided by the present invention includes a drive rod. One end of the drive rod is provided with a first U-shaped fork and a second U-shaped fork that are spaced apart side by side. Both the first U-shaped fork and the second U-shaped fork have openings in a direction perpendicular to the length direction of the drive rod, and the openings of the first U-shaped fork and the second U-shaped fork face the same direction.

[0015] When aligning the first and second pipelines that need to be connected, the construction personnel can place the first U-shaped fork on the first pipeline and the second U-shaped fork on the second pipeline, and position the drive rod on the side where the pipelines have shifted. For example, if the first pipeline has shifted downwards by a predetermined distance relative to the second pipeline, the drive rod is placed below the connection point of the first and second pipelines. Then, by moving the drive rod, the ends of the first and second pipelines can be moved by the first and second U-shaped forks, thus easily and quickly aligning the ends of the first and second pipelines.

[0024] The following reference Figure 1 and Figure 2 This application describes a pipe alignment auxiliary tooling according to some embodiments.

[0025] This application provides an auxiliary tooling for pipeline alignment, such as... Figure 1 As shown, the pipeline alignment auxiliary tooling includes a drive rod 3. One end of the drive rod 3 is provided with a first U-shaped fork 5 and a second U-shaped fork 6 spaced apart side by side. Both the first U-shaped fork 5 and the second U-shaped fork 6 have openings in a direction perpendicular to the length direction of the drive rod 3, and the openings of the first U-shaped fork 5 and the second U-shaped fork 6 face the same direction.

[0026] When aligning the first and second pipelines that need to be connected, such as Figure 2 As shown, the construction worker can clamp the first U-shaped fork 5 onto the first pipeline and the second U-shaped fork 6 onto the second pipeline, and position the drive rod 3 on the side where the pipeline is offset. For example, if the first pipeline is offset downwards by a predetermined distance relative to the second pipeline, the drive rod 3 is placed below the junction of the first and second pipelines. Then, by moving the drive rod 3, the ends of the first and second pipelines can be moved by the first U-shaped fork 5 and the second U-shaped fork 6, thus easily and quickly aligning the ends of the first and second pipelines.

[0027] In this embodiment, preferably, as follows: Figure 1 As shown, the pipeline alignment auxiliary tooling also includes a U-shaped fork 4. The U-shaped fork 4 includes a connecting arm, a first support arm 1, and a second support arm 2. The first support arm 1 and the second support arm 2 are arranged parallel to each other and connected by the connecting arm to form a U-shaped structure. The U-shaped fork 4 is connected to one end of the drive rod 3 through the connecting arm. The first support arm 1 and the second support arm 2 both extend in a direction parallel to the drive rod 3, and the opening of the U-shaped fork 4 is located on the side away from the drive rod 3.

[0028] The first U-shaped fork head 5 is formed on the first support arm 1, and the second U-shaped fork head 6 is formed on the second support arm 2.

[0029] Preferably, such as Figure 1As shown, the first support arm 1 is provided with a first limiting rod 51 and a second limiting rod 52. For the plane defined by the axis of the first support arm 1 and the axis of the second support arm 2, the first limiting rod 51 and the second limiting rod 52 are both perpendicular to the plane. The first limiting rod 51 and the second limiting rod 52 are arranged side by side at intervals along the length direction of the first support arm 1 and are respectively perpendicularly connected to the first support arm 1, thereby defining the first U-shaped fork head 5 of the U-shaped structure on the first support arm 1 through the first limiting rod 51 and the second limiting rod 52.

[0030] Similarly, the second support arm 2 is provided with a third limiting rod 61 and a fourth limiting rod 62. For the plane defined by the axis of the first support arm 1 and the axis of the second support arm 2, the third limiting rod 61 and the fourth limiting rod 62 are both perpendicular to the plane. The third limiting rod 61 and the fourth limiting rod 62 are arranged side by side at intervals along the length direction of the second support arm 2 and are respectively perpendicular to the second support arm 2, thereby defining the second U-shaped fork head 6 with a U-shaped structure on the second support arm 2 through the third limiting rod 61 and the fourth limiting rod 62.

[0031] In this embodiment, preferably, as follows: Figure 1 As shown, for the first limiting rod 51 and the second limiting rod 52 on the first support arm 1, at least one of them is adjustable in the installation position along the length direction of the first support arm 1, so that the distance between the first limiting rod 51 and the second limiting rod 52 can be adjusted to adapt to the first pipeline with different diameters.

[0032] The adjustable limiting rod among the first limiting rod 51 and the second limiting rod 52 is defined as the first movable limiting rod. In this embodiment, preferably, the first support arm 1 is provided with a first internal threaded connection hole, and the end of the first movable limiting rod used to connect with the first support arm 1 is provided with a first external threaded connection part. The first external threaded connection part is adapted to the first internal threaded connection hole, so that the first movable limiting rod can be detachably screwed onto the first support arm 1. The first support arm 1 is provided with multiple first internal threaded connection holes, which are arranged side-by-side at intervals along the length of the first support arm 1. Therefore, by installing the first movable limiting rod at different first internal threaded connection holes, the installation position of the first movable limiting rod on the first support arm 1 can be adjusted, thereby adjusting the distance between the first limiting rod 51 and the second limiting rod 52 to accommodate first pipelines of different diameters.

[0033] In this embodiment, preferably, as follows: Figure 1 As shown, for the third limiting rod 61 and the fourth limiting rod 62 on the second support arm 2, at least one of them is adjustable in the installation position along the length direction of the second support arm 2, so that the distance between the third limiting rod 61 and the fourth limiting rod 62 can be adjusted to adapt to the second pipeline with different diameters.

[0034] The adjustable limiting rod among the third limiting rod 61 and the fourth limiting rod 62 is defined as the second movable limiting rod. In this embodiment, preferably, the second support arm 2 is provided with a second internal threaded connection hole, and the end of the second movable limiting rod used to connect with the second support arm 2 is provided with a second external threaded connection part. The second external threaded connection part is adapted to the second internal threaded connection hole, so that the second movable limiting rod can be detachably screwed onto the second support arm 2. The second support arm 2 is provided with multiple second internal threaded connection holes, which are arranged side-by-side and spaced apart along the length of the second support arm 2. Therefore, by installing the second movable limiting rod at different second internal threaded connection holes, the installation position of the second movable limiting rod on the second support arm 2 can be adjusted, thereby adjusting the distance between the third limiting rod 61 and the fourth limiting rod 62 to accommodate second pipelines of different diameters.

[0035] In one embodiment of this application, preferably, the first U-shaped fork 5 is covered with a buffer sleeve, such as a rubber buffer sleeve, specifically, the buffer sleeve is fitted onto the first limiting rod 51, the second limiting rod 52, and the first support arm 1 between them. This prevents damage to the surface of the first pipeline when the first U-shaped fork 5 is engaged with it, and also avoids corrosion of the stainless steel first pipeline surface due to contact between the carbon steel and carbon steel, especially for the first U-shaped fork 5 made of carbon steel.

[0036] Similarly, the second U-shaped fork head 6 is also wrapped with a buffer sleeve, specifically on the third limit rod 61, the fourth limit rod 62 and the second support arm 2 between them.

[0037] In one embodiment of this application, preferably, the drive rod 3 is fitted with an anti-slip rubber sleeve to facilitate the grip of construction workers.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
