The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figures 1-4 , a pipe clamping mechanism for weld detection, including a workbench 1 and a weld detector 5. Two chutes 15 are opened on both sides of the workbench 1. A carriage 2 is slidably connected between the two chutes 15. Fixing blocks 13 are fixed on both sides of the carriage 2 by bolts. A second bolt 16 is inserted into the inside of the fixing block 13. A plurality of jacks 14 are opened on the upper surface of the workbench 1, and the second bolt 16 is inserted into the jacks 14 with corresponding dimensions. Push the carriage 2 to move it along the chute 15, and adjust the distance between the two carriages 2 according to the length of the pipe. Then insert the second bolt 16 into the jack 14, so as to fix the position between the carriages 2. A plurality of second cylindrical grooves 17 are opened on the inclined surface of the carriage 2. A second rotating column 18 is rotatably connected in the second cylindrical groove 17. An elastic steel plate 6 is rotatably connected to the top of the carriage 2. A plurality of through holes 19 are opened inside the elastic steel plate 6. A first bolt 10 is inserted into one side of the carriage 2, and the first bolt 10 communicates with the corresponding through hole 19. Place the two pipes on the carriages 2 at both ends of the workbench 1 respectively, move the elastic steel plate 6 to make it in close contact with the top surface of the pipe, and then insert the first bolt 10 into the through hole 19 at the corresponding position, so as to limit and fix the pipe by the elastic steel plate 6. A plurality of third cylindrical grooves 20 are opened at the bottom of the elastic steel plate 6. A third rotating column 21 is rotatably connected in the third cylindrical groove 20. A power assembly is arranged at the bottom of the carriage 2. The slide plate 7 moves upward to make the first rotating column 12 in close contact with the pipe, and then rotates the first rotating column 12 through the power assembly, so as to rotate the clamped pipe. At the same time, the second rotating column 18 and the third rotating column 21 assist the pipe to rotate.

[0024] In the present utility model, it should be noted that the power assembly includes a sliding plate 7 which is slidably connected to the bottom of the sliding frame 2. A first cylindrical groove 11 is formed in the top of the sliding plate 7, and a first rotating column 12 is rotatably connected to the inside of the first cylindrical groove 11. One side of the sliding plate 7 is fixed with a motor by bolts, and one end of the output shaft of the motor is fixed to the first rotating column 12. An electric push rod 8 is fixed to the bottom of the sliding frame 2 by bolts, and the extending end of the electric push rod 8 is fixed to the bottom of the sliding plate 7. When the electric push rod 8 extends, the first rotating column 12 on the sliding plate 7 is in close contact with the pipeline. When the motor rotates, the first rotating column 12 rotates.

A guide rod is fixed in the chute 15 by bolts, and the sliding frame 2 is slidably connected to the guide rod.

[0025] Working principle: When it is necessary to detect the weld of the pipeline, first push the sliding frame 2 to move it along the chute 15 to adjust the distance between the two sliding frames 2 according to the length of the pipeline. Then insert the second pin 16 into the jack 14 to fix the position between the sliding frames 2. Place the two pipelines on the sliding frames 2 at both ends of the workbench 1 respectively. Move the elastic steel plate 6 to make it in close contact with the top surface of the pipeline. Then insert the first pin 10 into the through hole 19 at the corresponding position to limit and fix the pipeline by the elastic steel plate 6. Then start the electric push rod 8 and the motor. When the electric push rod 8 extends, the first rotating column 12 on the sliding plate 7 is in close contact with the pipeline. When the motor rotates, the first rotating column 12 rotates, so that the clamped pipeline rotates. Push the slider 4 to drive the weld detector 5 to move along the T-shaped sliding rail 3 to the bottom of the weld, so that the weld detector 5 can detect the pipeline weld.
