[0043] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0044] The following describes a pipe alignment tool according to an embodiment of the present invention with reference to the accompanying drawings. The pipe includes a first pipe 1 and a second pipe 2. The first pipe 1 has a first port 11 and a second port, and the second pipe 2 has a third port 21 and a fourth port. The first port 11 of the first pipe 1 is adjacent to one end of the second pipe 2, and the third port 21 of the second pipe 2 is adjacent to one end of the first pipe 1. Specifically, in the initial position, the first pipe 1 and the second pipe 2 are generally aligned, and the first pipe 1 and the second pipe 2 are two pipes that need to be aligned, that is, the first pipe 1 and the second pipe 2 need to be coaxial, and the first port 11 and the third port 21 need to be aligned so that the first port 11 and the third port 21 can be welded together.

[0045] like Figures 1 to 3 As shown, the pipeline alignment tool according to an embodiment of the present invention includes a fixing part and an adjusting part.

[0046] The fixing part includes a first fixing member 3 and a second fixing member 4. The first fixing member 3 is used to be fixed on the outer circumferential surface of the first pipe 1, and the first fixing member 3 is adjacent to the first port 11 of the first pipe 1 in the length direction of the first pipe 1. The second fixing member 4 is used to be fixed on the outer circumferential surface of the second pipe 2, and the second fixing member 4 is adjacent to the third port 21 of the second pipe 2 in the length direction of the second pipe 2. Specifically, the first fixing member 3 is connected to the first pipe 1, so that the first fixing member 3 and the first pipe 1 can form a whole, and then the first pipe 1 can be moved by the first fixing member 3. Similarly, the second pipe 2 can be moved by the second fixing member 4. For example, the first fixing member 3 and the second fixing member 4 are both metal blocks, the first fixing member 3 is welded on the outer circumferential surface of the first port 11 of the first pipe 1, and the second fixing member 4 is welded on the outer circumferential surface of the third port 21 of the second pipe 2.

[0047] The adjusting part includes a first adjusting member 5 and a second adjusting member 6, the first adjusting member 5 is connected to the first fixing member 3, and the second adjusting member 6 is connected to the second fixing member 4. The first adjusting member 5 can drive (push) the first fixing member 3 to move (slide) in a direction adjacent to or away from the second pipe 2 so that the first port 11 moves in a direction adjacent to or away from the second pipe 2, and the first adjusting member 5 can drive (pull) the first fixing member 3 to move (rotate) relative to the second port to adjust the axial direction of the first pipe 1, and the adjusting part cooperates with the fixing part so that the first pipe 1 and the second pipe 2 are coaxially arranged and the distance between the first port 11 and the third port 21 is a first preset value. Specifically, the movement includes sliding and rotating. The first adjusting member 5 and the second adjusting member 6 are connected to the first fixing member 3 and the second fixing member 4 respectively, the first adjusting member 5 can drive the first fixing member 3 to move or limit the first fixing member 3, and the second adjusting member 6 can drive the second fixing member 4 to move or limit the second fixing member 4. The first preset value is greater than or equal to 0.8 mm and less than or equal to 1.2 mm, so as to facilitate welding.

[0048] The first adjusting member 5 can drive (push) the first fixing member 3 to move (slide) toward or away from the second pipe 2 so that the first port 11 moves toward or away from the second pipe 2, that is, the first adjusting member 5 can adjust the distance between the first pipe 1 and the second pipe 2 (the first port 11 and the third port 21) through the first fixing member 3. The first adjusting member 5 can drive (pull) the first fixing member 3 to move (rotate) relative to the second port to adjust the axial direction of the first pipe 1, so that the first pipe 1 and the second pipe 2 (the first port 11 and the third port 21) can be coaxially arranged. The first adjusting member 5 and the second adjusting member 6 can adjust the position of at least one of the first pipe 1 and the second pipe 2, so as to facilitate the alignment of the pipes, and then facilitate the welding of the pipes (the first pipe 1 and the second pipe 2).

[0049] Therefore, the pipeline alignment tool according to the embodiment of the present invention has the advantage of being convenient for pipeline alignment.

[0050] In some embodiments, the second adjusting member 6 can drive the second fixing member 4 to move toward or away from the first pipe 1 so that the third port 21 moves toward or away from the first pipe 1, and the second adjusting member 6 can drive the second fixing member 4 to move relative to the fourth port to adjust the axial direction of the second pipe 2. For example, the first adjusting member 5 and the second adjusting member 6 are mechanical arms.

[0051] like Figures 1 to 3 As shown, in some embodiments, there are multiple fixing parts and multiple adjusting parts, and the multiple adjusting parts are matched with the multiple fixing parts in a one-to-one correspondence. The multiple first fixing members 3 of the multiple fixing parts are arranged at intervals along the circumferential direction on the outer circumference of the first pipe 1. The multiple second fixing members 4 of the multiple fixing parts are arranged at intervals along the circumferential direction on the outer circumference of the second pipe 2. Specifically, the first fixing member 3 and the second fixing member 4 of each fixing part are (substantially) located at the same position in the circumferential direction, and the first adjusting member 5 and the second adjusting member 6 of the corresponding adjusting part are respectively connected to the first fixing member 3 and the second fixing member 4 of the corresponding fixing part.

[0052] In some embodiments, the adjusting portion includes a connecting frame 7, a first adjusting member 5, a second adjusting member 6 and a plurality of wedges 8, wherein the first adjusting member 5 and the second adjusting member 6 are disposed at both ends of the length direction of the connecting frame 7. For example, the first pipeline 1 is located on the left side of the second pipeline 2, the left end of the connecting frame 7 is welded to the first adjusting member 5, and the right end of the connecting frame 7 is welded to the second adjusting member 6.

[0053] like Figures 1 to 3 As shown, the first adjusting member 5 includes a first limiting plate 51 , a second limiting plate 52 and a third limiting plate 53 .

[0054] The first limiting plate 51 and the second limiting plate 52 are arranged at intervals (arranged in parallel) in the length direction of the connecting frame 7, and the first fixing member 3 is located between the first limiting plate 51 and the second limiting plate 52 in the length direction of the connecting frame 7. The distance between the first limiting plate 51 and the second limiting plate 52 is greater than the distance of the first fixing member 3 in the length direction of the connecting frame 7. Specifically, the first fixing member 3 can slide relative to the first limiting plate 51 and the second limiting plate 52 (in the length direction of the connecting frame 7), and the maximum distance value between the first fixing member 3 and one of the first limiting plate 51 and the second limiting plate 52 is greater than or equal to 2 cm and less than or equal to 3 cm. For example, the value of the distance between the first limiting plate 51 and the second limiting plate 52 minus the value of the distance of the first fixing member 3 in the length direction of the connecting frame 7 is greater than or equal to 2 cm and less than or equal to 3 cm. The first limiting plate 51 and the second limiting plate 52 are arranged at intervals in the left-right direction, and the first fixing member 3 is located between the first limiting plate 51 and the second limiting plate 52 in the left-right direction.

[0055] The third limiting plate 53 is located between the first limiting column 31 of the first fixing member 3 and the first pipeline 1. The third limiting plate 53 is connected to the first limiting plate 51 and the second limiting plate 52 at both ends in the length direction of the connecting frame 7, respectively. The third limiting plate 53 has a first limiting hole 54 passing through it. The size of the first limiting hole 54 in the length direction of the connecting frame 7 is larger than the size of the first fixing member 3 in the length direction of the connecting frame 7. The first fixing member 3 is slidably arranged in the first limiting hole 54 along the length direction of the connecting frame 7. The first fixing member 3 passes through the first limiting hole 54 and is connected to the first pipeline 1.

[0056] In some embodiments, the first fixing member 3 has a first fixing hole passing through it, and the first limiting column 31 is arranged in the first fixing hole. The extension direction of the first fixing hole and the first limiting column 31 is perpendicular to the length direction of the connecting frame 7. The first limiting column 31 is located between the first limiting plate 51 and the second limiting plate 52, and the third limiting plate 53 is located between the first pipe 1 and the first limiting column 31. Specifically, the first fixing member 3 can be welded to the first pipe 1, and then the first limiting hole 54 of the first adjusting member 5 is matched on the outer peripheral side of the first fixing member 3, and the first limiting column 31 is inserted into the first fixing hole, and the first limiting column 31 is located on the side of the third limiting plate 53 facing away from the first pipe 1, so that the first limiting column 31 and the first fixing member 3 form a fixing part connected to the first adjusting member. For example, in the length direction of the connecting frame 7, the value of the first limiting hole 54 minus the value of the first fixing member 3 is greater than or equal to 2 cm and less than or equal to 3 cm.

[0057] like Figures 1 to 3 As shown, the second adjusting member 6 includes a fourth limiting plate 61 , a fifth limiting plate 62 and a sixth limiting plate 63 .

[0058] The fourth limiting plate 61 and the fifth limiting plate 62 are arranged at intervals (arranged in parallel) in the length direction of the connecting frame 7, and the second fixing member 4 is located between the fourth limiting plate 61 and the fifth limiting plate 62 in the length direction of the connecting frame 7, and the distance between the fourth limiting plate 61 and the fifth limiting plate 62 is greater than the distance of the second fixing member 4 in the length direction of the connecting frame 7. Specifically, the second fixing member 4 can slide relative to the fourth limiting plate 61 and the fifth limiting plate 62 (in the length direction of the connecting frame 7), and the maximum distance value between the second fixing member 4 and one of the fourth limiting plate 61 and the fifth limiting plate 62 is greater than or equal to 2 cm and less than or equal to 3 cm. For example, the value of the distance between the fourth limiting plate 61 and the fifth limiting plate 62 minus the value of the distance of the second fixing member 4 in the length direction of the connecting frame 7 is greater than or equal to 2 cm and less than or equal to 3 cm. The fourth limiting plate 61 and the fifth limiting plate 62 are arranged at intervals in the left-right direction, and the second fixing member 4 is located between the fourth limiting plate 61 and the fifth limiting plate 62 in the left-right direction.

[0059] The sixth limiting plate 63 is located between the second limiting column 41 of the second fixing member 4 and the first pipeline 1. The sixth limiting plate 63 is connected to the fourth limiting plate 61 and the fifth limiting plate 62 at both ends in the length direction of the connecting frame 7, respectively, and the sixth limiting plate 63 has a second limiting hole 64 passing through it. The size of the second limiting hole 64 in the length direction of the connecting frame 7 is larger than the size of the second fixing member 4 in the length direction of the connecting frame 7, and the second fixing member 4 is slidably arranged in the second limiting hole 64 along the length direction of the connecting frame 7, and the second fixing member 4 passes through the second limiting hole 64 and is connected to the second pipeline 2.

[0060] In some embodiments, the second fixing member 4 has a second fixing hole running through it, and the second limiting column 41 is arranged in the second fixing hole. The extension direction of the second fixing hole and the second limiting column 41 is perpendicular to the length direction of the connecting frame 7. The second limiting column 41 is located between the fourth limiting plate 61 and the fifth limiting plate 62, and the sixth limiting plate 63 is located between the second pipe 2 and the second limiting column 41. Specifically, the second fixing member 4 can be welded to the second pipe 2, and then the second limiting hole 64 of the second adjusting member 6 is matched on the outer peripheral side of the second fixing member 4, and the second limiting column 41 is inserted into the second fixing hole, and the second limiting column 41 is located on the side of the sixth limiting plate 63 facing away from the second pipe 2, so that the second limiting column 41 and the second fixing member 4 form a fixing part connected to the second adjusting member. For example, in the length direction of the connecting frame 7, the value of the second limiting hole 64 minus the value of the second fixing member 4 is greater than or equal to 2 cm and less than or equal to 3 cm.

[0061] In some embodiments, the third limiting plate 53 is an arc-shaped plate matched with the first limiting column 31, the concave surface of the third limiting plate 53 contacts the first limiting column 31, and the first limiting column 31 can rotate relative to the third limiting plate 53. The sixth limiting plate 63 is an arc-shaped plate matched with the second limiting column 41, the concave surface of the sixth limiting plate 63 contacts the second limiting column 41, and the sixth limiting plate 63 can rotate relative to the second limiting column 41.

[0062] like Figure 3 As shown, in some embodiments, each of the first limiting column 31 and the second limiting column 41 is connected to the connecting frame 7 through a connecting rope. Specifically, the connecting frame 7 is provided with a connecting ring, and each of the first limiting column 31 and the second limiting column 41 is connected to the connecting rope through a connecting rope. For example, the connecting rope is supported by a chain.

[0063] Each of the first limiting column 31 and the second limiting column 41 is a tapered cylinder. Each of the first limiting column 31 and the second limiting column 41 is a tapered cylinder. It is convenient for the first limiting column 31 to be inserted into the first fixing hole, and the second limiting column 41 to be inserted into the second fixing hole. The tapered cylinder is a geometric body formed by cutting off a portion of the top of a right circular cone. The cutting surface is parallel to the bottom surface of the cone and is between the bottom surface and the vertex.

[0064] like Figures 1 to 3 As shown, in some embodiments, the connecting frame 7 has a first adjustment surface 71, a concave surface 72, and a second adjustment surface 73 connected in sequence, the first adjustment surface 71 faces the first pipeline 1, and the second adjustment surface 73 faces the second pipeline 2. Specifically, the connecting frame 7 is plate-shaped, and the first adjustment surface 71, the concave surface 72, and the second adjustment surface 73 are sequentially arranged in the length direction of the connecting frame 7.

[0065] The first adjustment surface 71 and the second adjustment surface 73 are coplanar, or the first adjustment surface 71 and the second adjustment surface 73 are arranged in parallel. Specifically, the first adjustment surface 71 and the second adjustment surface 73 are located between the first adjustment member 5 and the second adjustment member 6. The first adjustment surface 71 and the second adjustment surface 73 are at the same distance from the first pipeline 1 (or the second pipeline 2). Alternatively, the first adjustment surface 71 and the second adjustment surface 73 are at unequal distances from the first pipeline 1 (or the second pipeline 2), so that the wedge 8 can be inserted into the first adjustment surface 71 and the second adjustment surface 73 at unequal distances. For example, the distance between the first adjustment surface 71 and the first pipeline 1 (or the second pipeline 2) is smaller than the distance between the second adjustment surface 73 and the first pipeline 1 (or the second pipeline 2).

[0066] like Figures 1 to 3As shown, the wedge 8 can be inserted into at least one of the gap between the first pipeline 1 and the first adjusting member 5, the gap between the first pipeline 1 and the connecting frame 7, the gap between the second pipeline 2 and the second adjusting member 6, and the gap between the second pipeline 2 and the connecting frame 7 so that the first pipeline 1 and the second pipeline 2 are coaxially arranged. Specifically, the first pipeline 1 and the second pipeline 2 are coaxially arranged, and the first fixing member 3 or the second fixing member 4 needs to be pulled so that the first pipeline 1 or the second pipeline 2 can be rotated (swinged outward) so as to adjust the axial direction of one of the first pipeline 1 and the second pipeline 2, so as to be coaxially arranged with the other. The wedge 8 is inserted into the gap between the first pipeline 1 and the adjusting part (at least one of the connecting frame 7, the first adjusting member 5 and the second adjusting member 6), and the gap between the second pipeline 2 and the adjusting part (at least one of the connecting frame 7, the first adjusting member 5 and the second adjusting member 6) so as to drive the first fixing member 3 or the second fixing member 4 to move outward (away from the pipeline). For example, the wedge block 8 can be inserted into the second adjustment surface 73, so that the second adjustment member 3 can abut against the second limiting column 41. During the continuous insertion of the wedge block 8, the thicker the wedge block 8 is inserted, the greater the distance between the second adjustment surface 73 and the second pipe 2, thereby driving the connecting frame 7 to rotate relative to the second limiting column 41, thereby driving the first adjustment member 5 to drive the first limiting column 31 to move outward, thereby allowing the first port 11 of the first pipe 1 to rotate, so as to adjust the axial direction of the first pipe 1.

[0067] The wedge block 8 can be inserted into at least one of the gap between the first fixing member 3 and the first limiting plate 51, the gap between the first fixing member 3 and the second limiting plate 52, the gap between the second fixing member 4 and the fourth limiting plate 61, and the gap between the second fixing member 4 and the fifth limiting plate 62 to adjust the distance between the first port 11 and the third port 21. For example, the first limiting plate 51, the second limiting plate 52, the fourth limiting plate 61, and the fifth limiting plate 62 are sequentially arranged in the length direction (left-right direction) of the connecting frame 7. When the distance between the first pipeline 1 and the second pipeline 2 is close and needs to be separated, the wedge block 8 can be inserted into the gap between the first fixing member 3 and the second limiting plate 52, or the wedge block 8 can be inserted into the gap between the second fixing member 4 and the fourth limiting plate 61.

[0068] The pipe alignment tool according to the embodiment of the present invention has a simple structure and is easy to process and manufacture. It is suitable for the alignment of large-diameter pipes of various specifications and thick walls of various materials. The tool can be used repeatedly and has a wide range of applications. It can improve the alignment accuracy, reduce the amount of misalignment, and reduce costs. It can adjust the weld gap of the aligned pipes to ensure that the weld gap is at the optimal size, thereby effectively improving the subsequent welding efficiency. At the same time, when aligning large-diameter pipes, there is no need to use adjustment tools such as lifting machinery and chain hoists, which reduces mechanical damage and improves economic efficiency.

[0069] The present invention also proposes a pipeline alignment method using the pipeline alignment tool according to an embodiment of the present invention. The pipeline alignment method according to an embodiment of the present invention comprises the following steps:

[0070] Multiple first fixing members 3 of multiple fixing parts are welded to the outer circumference of the first pipe 1 and the multiple first fixing members 3 are spaced apart in the circumferential direction, and multiple second fixing members 4 of multiple fixing parts are welded to the outer circumferential surface of the second pipe 2 and the multiple second fixing members 4 are spaced apart in the circumferential direction. That is, multiple fixing parts are used.

[0071] The first adjusting members 5 of the multiple adjusting parts are matched one by one with the multiple first fixing members 3, and the second adjusting members 6 of the multiple adjusting parts are matched one by one with the multiple second fixing members 4. Thus, the multiple adjusting parts are connected to the multiple fixing parts one by one.

[0072] The wedge block 8 can be inserted into at least one of the gap between the first pipe 1 and the first adjusting member 5, the gap between the first pipe 1 and the connecting frame 7, the gap between the second pipe 2 and the second adjusting member 6, and the gap between the second pipe 2 and the connecting frame 7 so that the first pipe 1 and the second pipe 2 are coaxially arranged.

[0073] The wedge block 8 can be inserted into at least one of the gap between the first fixing member 3 and the first limiting plate 51, the gap between the first fixing member 3 and the second limiting plate 52, the gap between the second fixing member 4 and the fourth limiting plate 61, and the gap between the second fixing member 4 and the fifth limiting plate 62 to adjust the distance between the first port 11 and the third port 21. Through multiple wedge blocks 8, the positions of multiple adjusting members in the circumferential direction can be adjusted, thereby driving the corresponding first fixing member 3 and the second fixing member 4 to move (slide, rotate), so that the first pipeline 1 and the second pipeline 2 are coaxially arranged and adjacent to each other. After the adjustment process and the adjustment is completed, a measuring tool such as a level ruler can be used to measure whether the first pipeline 1 and the second pipeline 2 are coaxially arranged and the distance between the first pipeline 1 and the second pipeline 2.

[0074] Therefore, the pipeline alignment method according to the embodiment of the present invention has the advantage of being easy to align the pipeline.

[0075] In some embodiments, the adjusting portion cooperates with the fixing portion so that the first pipe 1 and the second pipe 2 are coaxially arranged and the distance between the first port 11 and the third port 21 is greater than or equal to 0.8 mm and less than or equal to 1.2 mm. For example, the adjusting portion cooperates with the fixing portion so that the distance between the first port 11 and the third port 21 is 1 mm.

[0076] In some embodiments, the number of the adjusting parts and the fixing parts is greater than or equal to three sets. Specifically, the larger the diameter of the pipeline, the more the adjusting parts and the fixing parts are used. For example, the number of the adjusting parts and the fixing parts is four sets. For a pipeline with a diameter of DN1000, six sets of adjusting parts and the fixing parts can be used. For a pipeline with a diameter greater than DN1000, the number of the adjusting parts and the fixing parts is greater than or equal to eight sets, which can achieve a better adjustment effect.
