In the process of pipeline weld joint assembly and welding, the accuracy of pipeline weld joint assembly is one of the important links in ensuring the quality of pipeline welding.

[0003] Existing pipe alignment devices cannot guarantee that the forces on both sides of the welded pipe are the same when aligning pipes. This can easily lead to misalignment inside the pipe during alignment, making it difficult to ensure the concentricity and coaxiality of the two sides of the welded pipe assembly. Consequently, it is difficult to guarantee the quality and accuracy of pipe alignment and affect the quality of pipe welding. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] A typical embodiment of this utility model is as follows: Figure 1 As shown, a pipe alignment adjustment device includes a support shaft 1, on which a support tube 2 is sleeved. There are two support tubes 2, symmetrically arranged at both ends of the support shaft 1. A support ring 3 is also sleeved on the support shaft 1 between the two support tubes 2. There are two support rings 3. A spring 4 is sleeved on the support shaft 1 between the support ring 3 and the support tube 2. The two ends of the spring 4 are connected to the support tube 2 and the support ring 3 respectively. The support ring 3 can slide along the axial direction of the support shaft 1. When the support ring 3 moves, it can be reset by the elastic force of the spring 4.

[0020] Multiple first adjusting plates 5 are hinged to the outer circular surface of the support ring 3. In this embodiment, there are four first adjusting plates 5, which are symmetrically arranged in pairs. Multiple second adjusting plates 6 are hinged to the outer circular surface of the end of the support tube 2 away from the support ring 3. In this embodiment, there are four second adjusting plates 6, which are symmetrically arranged in pairs. The ends of the first adjusting plates 5 away from the support ring 3 and the ends of the second adjusting plates 6 away from the support tube 2 are both connected to the support plate 7. The first adjusting plates 5 and the second adjusting plates 6 are respectively hinged to both ends of the support plate 7. A support arc plate 8 is provided on the upper surface of the support plate 7. The support arc plate 8 has a certain curvature. The outer surface of the support arc plate 8 is adapted to the inner wall of the pipe 16, so that the support arc plate 8 is firmly in contact with the inner wall of the pipe 16 when it is open, and perfectly fits the support tube 2 when it is tightened, without occupying other space.

[0021] When in use, the support shaft 1 is placed between two pipes 16 to be connected. The support arc plates 8 on both sides of the support shaft 1 are located inside the two pipes 16 to be connected. When the support ring 3 moves to the support pipe 2, under the action of the first adjusting plate 5 and the second adjusting plate 6, the support plate 7 drives the support arc plate 8 to open outward, thereby supporting the inner wall of the pipe 16.

[0022] like Figure 2As shown, a motor 9 and an adjusting shaft 10 are also provided on the support shaft 1. Both the motor 9 and the adjusting shaft 10 are sleeved on the outside of the support shaft 1 and located between the two support rings 3. The motor 9 is fixedly connected to one side of the support ring 3. The adjusting shaft 10 includes an inner connecting shaft 101 and an outer connecting shaft 102. The outer connecting shaft 102 is sleeved on the outside of the inner connecting shaft 101. The outer surface of the inner connecting shaft 101 is provided with an external thread, and the inner surface of the outer connecting shaft 102 is provided with an internal thread, so that the inner connecting shaft 101 and the outer connecting shaft 102 are threadedly connected. One end of the inner connecting shaft 101 is fixed on the other side of the support ring 3, and one end of the outer connecting shaft 102 is fixed on the output end of the motor 9. When the motor 9 rotates, it can drive the outer connecting shaft 102 to rotate. Since the outer connecting shaft 102 is threadedly connected to the inner connecting shaft 101, the inner connecting shaft 101 and the outer connecting shaft 102 move towards each other, thereby squeezing the support ring 3 and causing the support arc plate 8 to open outward.

[0023] A pressure sensor is installed between the support plate 7 and the support arc plate 8. A controller is installed inside the support shaft 1. The pressure sensor and the motor 9 are both connected to the controller. When the support arc plate 8 opens outward and contacts the inner wall of the pipe 16, the pressure sensor can detect the pressure between the support arc plate 8 and the inner wall of the pipe 16. When the pressure reaches the set value, the controller controls the motor 9 to stop working, thereby effectively supporting the pipe 16.

[0024] Since the motor 9 and the adjusting shaft 10 are located between the two support rings 3, when the adjusting shaft 10 moves to both sides, the two support rings 3 move synchronously, thereby driving the support arc plates 8 on both sides to open synchronously, which can realize the rapid centering of the pipe 16. At the same time, the two support pipes 2 are installed on the same support shaft 1, which can quickly achieve concentricity and coaxiality on both sides when assembling the weld joint, so that there is no misalignment inside the pipe 16, and the welding quality of the weld joint is improved.

[0025] The support shaft 1 has connecting rings 11 at both ends. One side of the connecting ring 11 is connected to the support tube 2, and the other end of the connecting ring 11 is connected to an adjusting support. The adjusting support includes a fixed plate 12, which is a circular steel plate. The axis of the fixed plate 12 coincides with the axis of the support shaft 1. Multiple adjusting nuts 13 are provided on the outer edge of the fixed plate 12. Adjusting screws 14 are threaded onto the adjusting nuts 13. The top end of the adjusting screws 14 is rotatably connected to a roller 15 through a roller bracket.

[0026] In use, by adjusting the length of the adjusting screw 14, the roller 15 is brought into contact with the inner wall of the pipe 16. A drive motor is fixedly installed on one side of the roller bracket, and the output shaft of the drive motor is fixedly connected to the roller 15, so that the adjusting device can move inside the pipe 16, allowing the adjusting device to quickly enter and exit the inside of the pipe 16.

[0027] Working principle When in use, first adjust the length of the screws at both ends of the support shaft so that the rollers can contact the inner wall of the pipe. Then, place the alignment adjustment device inside the pipe. With the alignment adjustment device in the tightened state, move it between the two pipes. The support arc plates on both sides of the alignment adjustment device are located inside the two pipes respectively. Start the motor, and the adjusting shaft will move to both sides, causing the support ring to open symmetrically to both sides and the support arc plate to open outward and contact the inside of the pipe. When the torque set by the gear is reached, the motor stops and remains fixed. After the assembly requirements are met, welding begins. When welding is completed or a certain strength is reached, the motor can be rotated to adjust the shaft to extend and retract, and the alignment adjustment device will begin to tighten. After tightening, the alignment adjustment device can be pulled out of the pipe.

[0028] This invention sets up two sets of symmetrical support pipes, so that the two sets of adjusting devices are subjected to the same force, and the support plates are opened evenly, ensuring that the two pipes are concentric and coaxial, so that there is no misalignment inside the pipes, thus improving the welding quality of the weld joint.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
