Pipe alignment tools, as a key component of automated pipeline welding equipment, are primarily used to quickly align two pipes to be joined, and also serve to correct pipe end roundness, adjust misalignment, and adjust the alignment gap.

[0003] However, the existing pipe alignment tools are cumbersome to load and unload, and the workload for operators is large when performing pipe alignment work, resulting in low work efficiency. Utility Model Content

[0004] The main purpose of this utility model is to propose a pipe alignment tool, which aims to improve the problem that the existing pipe alignment tool is cumbersome to load and unload, and the operators have a large workload when performing pipe alignment work, resulting in low work efficiency.

[0005] To achieve the above objectives, the pipe alignment tooling proposed in this utility model includes:

[0006] A limiting component includes two limiting structures spaced apart in a first direction, each limiting structure being open at one end facing the other limiting structure in the first direction, the open ends of the two limiting structures enclosing each other, and the two limiting structures being used to be jointly fitted onto the openings of two pipes; and...

[0007] Multiple adjustment structures are spaced apart from the two limiting structures along an axis extending in a second direction, and the multiple adjustment structures are movably arranged in a direction close to or away from the axis extending in the second direction of the limiting components, each of the adjustment structures being used to abut against the two pipes.

[0008] In one embodiment, each of the adjustment structures includes:

[0009] An adjustment part is movably disposed in one of the limiting structures along an axis extending in a second direction toward or away from the limiting component;

[0010] An abutment portion is provided at the adjustment portion, and the abutment portion is used to abut against the two pipes.

[0011] In one embodiment, the end of the abutting portion away from the corresponding adjusting portion is arranged in an arc shape toward the adjusting portion for abutting the two pipes.

[0012] In one embodiment, the abutting portion and the adjusting portion are detachably connected.

[0013] In one embodiment, the abutting portion includes an abutting wheel, which is rotatably disposed about an axis extending in a second direction.

[0014] In one embodiment, each of the adjustment units includes:

[0015] At least two threaded holes are spaced apart along the second direction in the corresponding limiting structure; and,

[0016] At least two adjusting bolts are inserted into the corresponding threaded holes and are threaded into the threaded holes;

[0017] The abutting part includes at least two abutting members, which are rotatably disposed on the corresponding adjusting bolt about the axis of the corresponding adjusting bolt, and the two abutting members are respectively used to abut against the two pipes.

[0018] In one embodiment, the shape of each of the limiting structures includes a semi-circular shape.

[0019] In one embodiment, each of the limiting structures includes:

[0020] Two semi-rings are arranged at intervals along the second direction; and,

[0021] Multiple connecting parts are arranged at intervals around an axis extending in a second direction, and each connecting part is respectively connected to two semi-ring bodies at both ends in the second direction;

[0022] In the two limiting structures, the two semi-rings of one limiting structure and the two semi-rings of the other limiting structure are used to enclose and sleeve the openings of the two pipes;

[0023] Each of the aforementioned adjustment structures is located at the corresponding connecting portion.

[0024] In one embodiment, each of the limiting structures has a first end and a second end disposed opposite to each other;

[0025] The pipe alignment fixture also includes a locking structure, which comprises:

[0026] First locking portions, each of the first locking portions being disposed at a first end of one of the limiting structures, and rotatably connected to the first end of the other limiting structure along an axis extending in a second direction; and,

[0027] The second locking part is disposed at the second end of one of the limiting structures and is detachably connected to the second end of the other limiting structure.

At this time, the open ends of the two restrictive structures enclose each other, so that the pipe openings of the two pipes are fitted into the two restrictive structures. At this time, multiple adjusting structures are activated. Since multiple adjusting structures are spaced apart on the two restrictive structures around the axis extending in the second direction, and multiple adjusting structures are movable in the direction close to or away from the axis extending in the second direction of the restrictive components, at least some of the adjusting structures can be driven to move towards the axis extending in the second direction of the restrictive components, thereby enabling at least some of them to move towards the axis extending in the second direction of the restrictive components. The adjusting structure can press against the two pipes to adjust the gap between their openings. Once the gap is determined, the remaining adjusting structures are driven to move towards the axis extending in the second direction from the limiting component, so that all the adjusting structures press against the two pipes, thereby changing the position of the pipe openings to make them coaxial, ensuring the normal progress of pipe welding. After the pipe welding is completed, simply driving the adjusting structures away from the axis extending in the second direction from the limiting component releases the enclosure of the two pipes by the limiting structures, allowing the pipe fitting fixture to be disassembled. This design ensures safe pipe welding, high-quality and efficient installation, and simplifies disassembly after welding, reducing the workload of operators and maximizing work efficiency and economic utilization.

[0040] This utility model proposes a pipe alignment tool. It aims to improve upon existing pipe alignment tools, which are cumbersome to install and remove, resulting in a heavy workload for operators and low work efficiency.

[0041] Please see Figure 1In one embodiment of this utility model, the pipe fitting fixture 100 includes a limiting component 1 and a plurality of adjusting structures 2. The limiting component 1 includes two limiting structures 11 spaced apart in a first direction. Each limiting structure 11 is open at one end in the first direction toward the other limiting structure 11. The open ends of the two limiting structures 11 are enclosed and fitted together at the pipe openings of the two pipes. The plurality of adjusting structures 2 are spaced apart on the two limiting structures 11 around an axis extending in a second direction. The plurality of adjusting structures 2 are movable in directions close to or away from the axis extending in the second direction of the limiting component 1. Each adjusting structure 2 is used to abut against the two pipes.

[0042] In the technical solution of this utility model, when it is necessary to align two pipes, firstly, the open sections of the two limiting structures 11 are arranged opposite each other. At this time, the open ends of the two limiting structures 11 surround each other to fit the pipe openings of the two pipes into the two limiting structures 11. At this time, multiple adjusting structures 2 are activated. Since multiple adjusting structures 2 are spaced apart on the two limiting structures 11 around the axis extending in the second direction, and multiple adjusting structures 2 are movable in the direction close to or away from the axis extending in the second direction of the limiting component 1, at least some of the adjusting structures 2 can be driven to move towards the axis extending in the second direction of the limiting component 1, thereby enabling at least Part of the adjustment structure 2 can abut against the two pipes to adjust the gap between the pipe openings. After the gap is determined, the remaining adjustment structure 2 is driven to move towards the axis extending in the second direction of the limiting component 1, so that all the adjustment structures 2 abut against the two pipes, thereby changing the position of the pipe openings so that the pipe openings are coaxial, ensuring the normal progress of pipe welding. After the pipe welding is completed, simply drive the multiple adjustment structures 2 away from the axis extending in the second direction of the limiting component 1 to release the enclosure of the two limiting structures 11 on the two pipes, thereby disassembling the pipe fitting fixture 100. This configuration ensures safe pipe welding, high-quality and efficient installation, and simple disassembly after pipe welding, reducing the workload of operators and maximizing work efficiency and economic utilization.

[0043] It is understood that, in this utility model, in order to ensure that the multiple adjustment structures 2 can smoothly and conveniently adjust the gap between the openings of the two pipes and the concentricity of the two pipes, in one embodiment of this utility model, each adjustment structure 2 includes an adjustment part 21 and an abutment part 22. The adjustment part 21 is movably disposed in one of the limiting structures 11 along an axis extending in a second direction close to or away from the limiting component 1. The abutment part 22 is disposed in the adjustment part 21 and is used to abut against the two pipes. With this configuration, when it is necessary to adjust the gap between the pipe openings of the two pipes and the concentricity of the two pipes, the operator only needs to drive the adjusting part 21 to move towards the axis extending in the second direction near the limiting component 1, so that the abutting part 22 presses against the two pipes. At this time, the abutting part will force the two pipes to move. Then, the operator drives multiple adjusting structures 2 to move, so that multiple abutting parts together force the two pipes to move. Under the joint calibration drive of multiple abutting parts, the gap between the pipe openings of the two pipes will decrease during the movement, and the concentricity of the two pipes will increase until all the abutting parts 22 press against the two pipes, and the two pipes are coaxially arranged to ensure the normal progress of pipe welding.

[0044] It should be noted that this utility model does not limit the specific structural form of the adjusting part 21. In one embodiment of this utility model, the adjusting part 21 can be configured as a telescopic rod, the main body of which is located on the limiting structure 11, and the rod portion of which is connected to the abutment part 22 to drive the abutment part 22 to move toward the axis extending in the second direction of the limiting component 1, thereby abutting the two pipes. In another embodiment of this utility model, the adjusting part 21 includes a threaded hole and an adjusting bolt. The threaded hole passes through the limiting structure 11, the adjusting bolt passes through the threaded hole, and the abutment part 22 is located on the adjusting bolt. With this configuration, the operator can rotate the adjusting bolt to drive the abutment part 22 to move toward the axis extending in the second direction of the limiting component 1, so that the abutment part 22 abuts the two pipes. In other embodiments of this utility model, the adjusting part 21 can also be configured with other structural forms, which can be selected according to the actual requirements.

[0045] It should be further explained that when the adjusting part 21 includes the threaded hole and the adjusting bolt, since the cross-sectional area of ​​the adjusting bolt in the second direction is small, in order to further improve the clamping and fixing ability of the adjusting structure 2 for the two pipes, in a further embodiment of this utility model, each adjusting part 21 includes at least two threaded holes and at least two adjusting bolts. The two threaded holes are arranged at intervals along the second direction in the corresponding limiting structure 11, and the two adjusting bolts pass through the corresponding threaded holes and are threadedly engaged with the threaded holes. The abutting part 22 includes at least two abutting members 221. The abutting members 221 are rotatably disposed on the corresponding adjusting bolt about the axis of the corresponding adjusting bolt, and the two abutting members 221 are respectively used to clamp the two pipes. With this configuration, in each of the adjustment structures 2, the two adjustment bolts can drive the corresponding abutment 221 to abut against the two pipes respectively. This not only further ensures the adjustment and fixing ability of the adjustment structure 2 on the pipes, but also further improves the precision of the pipe alignment work. Operators can adjust the position of one of the pipes individually according to the actual construction situation, so as to further improve the work quality of the pipe alignment work.

[0046] Furthermore, by setting two abutting parts 221 to abut against the two pipes respectively, the abutting part 22 can avoid the weld between the two pipes, thereby ensuring the normal progress of the welding work.

[0047] It is also understandable that when a user drives the corresponding abutment 221 to press against the pipe by rotating the adjusting bolt, in order to prevent the adjusting bolt from driving the corresponding abutment 221 to rotate and damage the pipe coating, the abutment 221 is rotatably mounted on the corresponding adjusting bolt around the axis of the corresponding adjusting bolt, so as to release the synchronous rotation of the abutment 221 and the adjusting bolt, and ensure the pressing effect between the abutment 221 and the pipe.

[0048] Of course, this utility model does not limit the specific structural form of the abutment part 22. In one embodiment of this utility model, the end of the abutment part 22 away from the corresponding adjustment part 21 is arranged in an arc shape towards the adjustment part 21 to abut against the two pipes. With this arrangement, the abutment part 22 is contoured to the abutment ends of the two pipes, so that the end of the abutment part 22 abutting against the two pipes can be closer to the shape of the two pipes, thereby increasing the contact area with the two pipes and making the pressure of the abutment part 22 on the two pipes uniform, thereby further protecting the coating of the two pipes.

[0049] Furthermore, to expand the applicability of the pipe alignment fixture 100, and to ensure that it can still accommodate pipes of various diameters even when the end of the abutment portion 22 away from the corresponding adjustment portion 21 is arc-shaped towards the adjustment portion 21, in a further embodiment of this invention, the abutment portion 22 and the adjustment portion 21 are detachably connected. With this configuration, when the pipe diameter changes, the operator can remove the abutment portion 22 from the adjustment portion 21 to replace it with an abutment portion 22 of the corresponding arc shape, thereby ensuring that the arc-shaped end face of the abutment portion 22 can adapt to the current pipe, thus expanding the applicability of the pipe alignment fixture 100.

[0050] In another embodiment of this utility model, the abutting part 22 further includes an abutting wheel, which is rotatably arranged about an axis extending in a second direction. With this arrangement, when multiple abutting wheels abut against the two pipes, so that the two pipes are coaxially arranged in the current state, the operator can drive the pipe alignment fixture 100 to rotate along the axis extending in the second direction, causing the positions of the multiple adjusting structures 2 relative to the pipes to change. This allows the operator to further check the concentricity of the two pipes and further improve the concentricity of the two pipes, thereby further improving the quality of the pipe alignment work, reducing the stress on the weld joints of the two pipes when the pipes are under load, and ensuring the quality of pipe welding.

[0051] In other embodiments of this utility model, the abutting part 22 can also be configured in other structural forms, which can be selected according to the actual requirements.

[0052] Furthermore, this utility model does not limit the specific structural form of the limiting structure 11. In one embodiment of this utility model, each of the limiting structures 11 includes a square frame, one end of which is open. In another embodiment of this utility model, each of the limiting structures 11 has a semi-circular shape. This arrangement allows the shape of the limiting structure 11 to fit the shape of the pipe more closely.

[0053] Specifically, in this invention, the shape of each of the limiting structures 11 includes a semi-circular shape.

[0054] When the shape of the limiting structure 11 is set as a semi-circular shape, in order to reduce the weight of the limiting structure 11 while ensuring the structural performance of the limiting structure 11, thereby reducing the workload of the operator, in one embodiment of the present invention, each limiting structure 11 includes two semi-circular bodies 111 and a plurality of connecting parts 112. The two semi-circular bodies 111 are arranged at intervals along the second direction, and the plurality of connecting parts 112 are arranged at intervals around the axis extending in the second direction. Each connecting part 112 is respectively connected to the two semi-circular bodies 111 at both ends in the second direction. In the two limiting structures 11, the two semi-circular bodies 111 of one limiting structure 11 and the two semi-circular bodies 111 of the other limiting structure 11 are used to enclose and sleeve the openings of the two pipes. Each adjusting structure 2 is provided on the corresponding connecting part 112. With this configuration, when operators need to perform pipe alignment work, the open ends of the two semi-rings 111 of the two limiting structures 11 are closed to fit onto the two pipes respectively. At this time, the multiple connecting parts 112 can ensure the relative stability of the two semi-rings 111 of each limiting structure 11, while providing installation space for the multiple adjusting structures 2 to ensure that the multiple adjusting structures 2 can adjust and fix the two pipes. This also significantly reduces the weight of the pipe alignment fixture 100, reduces the workload and intensity of the operators.

[0055] Furthermore, it should be noted that when the two limiting structures 11 surround and sleeve the openings of the two pipes, in order to ensure the strength of the enclosure connection of the two limiting structures 11 and thus ensure that the pipe alignment work can be carried out smoothly, in one embodiment of the present invention, each limiting structure 11 has a first end and a second end arranged opposite to each other. The pipe alignment fixture 100 also includes a locking structure 3. The locking structure 3 includes a first locking part 31 and a second locking part 32. Each first locking part 31 is disposed at the first end of one of the limiting structures 11 and is rotatably connected to the first end of the other limiting structure 11 along an axis extending in the second direction. Each second locking part 32 is disposed at the second end of one of the limiting structures 11 and is detachably connected to the second end of the other limiting structure 11.

[0056] In this embodiment, when it is necessary to fit the two limiting structures 11 onto the openings of the two pipes, the operator can release the connection between the second locking part 32 and the second end of the other limiting structure 11, so that the two limiting structures 11 can rotate relative to each other around the axis extending in the second direction of the first locking part 31. At this time, the second ends of the two limiting structures 11 are far apart from each other, and the operator can fit the two limiting structures 11 onto the openings of the two pipes. Then, the operator drives the two limiting structures 11 to rotate in the opposite direction around the axis extending in the second direction, so that the second ends of the two limiting structures 11 are close to each other, until the second locking part 32 reconnects to the second end of the other limiting structure 11. In this way, the fitting of the two limiting structures 11 is completed.

[0057] Of course, this utility model does not limit the detachable connection form between the second locking part 32 and the other limiting structure 11. In one embodiment of this utility model, the second locking part 32 is threadedly connected to the other limiting structure 11 by a locking bolt. With this configuration, when it is necessary to disconnect the connection between the second locking part 32 and the second end of the other limiting structure 11, the operator rotates the locking bolt to remove it; when it is necessary to reconnect the connection between the second locking part 32 and the second end of the other limiting structure 11, the operator reinstalls the locking bolt between the second locking part 32 and the second end of the other limiting structure 11.

[0058] In another embodiment of this utility model, the second locking structure 3 is provided with a first through hole along the second direction, and the other limiting structure 11 is provided with a second through hole corresponding to the first through hole. The locking structure 3 also includes a locking part 33, which is sequentially disposed through the first through hole and the second through hole along the second direction. With this configuration, when it is necessary to disconnect the second locking part 32 from the second end of the other limiting structure 11, the operator only needs to remove the locking part 33 from the first through hole and the second through hole. When it is necessary to reconnect the second locking part 32 from the second end of the other limiting structure 11, the operator only needs to insert the locking part 33 into the first through hole and the second through hole. The operation is convenient and simple, which can reduce the workload of the operator and further improve work efficiency.

[0059] In one embodiment of the present invention, the locking part 33 includes a pin; in another embodiment of the present invention, the locking part 33 includes a ring buckle; in other embodiments of the present invention, the locking part 33 may also be configured with other structural forms. In actual installation, it can be selected according to the requirements, and the present invention does not limit it.

[0060] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
