If it is actually used on site, it is necessary to prepare pressure pipeline detection devices of different specifications, which reduces the utilization rate of the pressure pipeline detection device and causes the pressure pipeline detection device to have limitations in use.

[0028] like Figure 3As shown, the rotating mechanism 6 includes: a flat screw disk 8 is rotatably connected inside the fixed box 3, a first bevel gear 9 is fixedly connected to the bottom of the flat screw disk 8, and a second bevel gear 10 is meshed with one side of the first bevel gear 9; a motor 11 is provided on the side of the second bevel gear 10 away from the first bevel gear 9, the motor 11 is fixedly connected to the fixed box 3, and the second bevel gear 10 is fixed to the outer surface of the output end of the motor 11, and the motor 11 is started, and the output end of the motor 11 drives the second bevel gear 10, the second bevel gear 10 drives the first bevel gear 9, and the first bevel gear 9 drives the flat screw disk 8 to rotate, and the flat screw disk 8 rotates while driving the claws 5, so that the six claws 5 move synchronously toward the pipe body 4, and then clamp the pipe body 4.

[0029] like Figure 5 As shown, the telescopic mechanism 7 includes: a hydraulic cylinder 12 is fixedly connected to the top of the gantry 2, and the telescopic end of the hydraulic cylinder 12 passes through the gantry 2 and extends to the lifting block 13. Both sides of the lifting block 13 are rotatably connected to the linkage rod 15 through the first rotating shaft 14; the end of the linkage rod 15 away from the first rotating shaft 14 is rotatably connected to the first pressure rod 17 and the second pressure rod 18 through the second rotating shaft 16, and the top of the first pressure rod 17 is rotatably connected to the first connecting frame 20 through the third rotating shaft 19, and the first connecting frame 20 is fixedly connected to the gantry 2, and the bottom end of the second pressure rod 18 is rotatably connected to the second connecting frame 22 through the fourth rotating shaft 21, and the second connecting frame 22 is fixedly connected to the lifting plate 23; the middle of the lifting plate 23 The part is provided with an electronic mechanism 24 for detecting the pressure value borne by the pipeline body 4.

The first pressure rod 17 rotates inside the first connecting frame 20 through the third rotating shaft 19 and presses down the second pressure rod 18 through the second rotating shaft 16. The second pressure rod 18 presses down the second connecting frame 22 through the fourth rotating shaft 21.

[0032] like Figure 6 As shown, the claw 5 includes a moving block 31, a two-way stepped positioning claw 32, a limiting block 33, a hexagon socket bolt 34 and a damping pad 35; the top of the moving block 31 is fixedly connected to the limiting block 33, the outer surface of the limiting block 33 is sleeved with a two-way stepped positioning claw 32, both sides of the two-way stepped positioning claw 32 are provided with a hexagon socket bolt 34, the hexagon socket bolt 34 penetrates the two-way stepped positioning claw 32 and extends to the moving block 31, the hexagon socket bolt 34 is threadedly connected to the moving block 31, and damping pads 35 are provided on both sides of the two-way stepped positioning claw 32, and the damping pads 35 are respectively fixedly connected to the two-way stepped positioning claw 32, the user can unscrew the hexagon socket bolt 34, turn the two-way stepped positioning claw 32 in direction, and then sleeve it on the outer surface of the limiting block 33, and finally fix it to the moving block 31 through the hexagon socket bolt 34, which greatly increases the maximum value range of the diameter of the pipe body 4 that can be clamped by the device and improves practicality.

[0033] like Figure 2 and Figure 4 As shown, two limit slide bars 36 are fixedly connected to the fixed box 3 near the moving block 31, and sliding grooves are provided on both sides of the moving block 31. The moving block 31 is slidingly connected to the limit slide bars 36 through the sliding grooves, and the moving block 31 can be limited, so that the moving block 31 and the fixed box 3 are slidingly connected.

[0034] Working principle: the user places the pipe body 4 to be inspected at the top center of the fixed box 3, and then starts the motor 11. The output end of the motor 11 drives the second bevel gear 10, the second bevel gear 10 drives the first bevel gear 9, and the first bevel gear 9 drives the flat screw plate 8 to rotate. The flat screw plate 8 rotates while driving the claws 5, so that the six claws 5 move synchronously toward the pipe body 4, and then clamp the pipe body 4, and then start the hydraulic cylinder 12. The telescopic end of the hydraulic cylinder 12 extends outward, pushing the lifting block 13 down. The lifting block 13 descends while driving the first rotating shaft 14. The first rotating shaft 14 pushes one end of the linkage rod 15, so that the other end of the linkage rod 15 pushes the first pressure rod 17 through the second rotating shaft 16. The first pressure rod 17 passes through the first pressure rod 17. While the three-axis 19 rotates inside the first connecting frame 20, it presses down the second pressure rod 18 through the second axis 16. The second pressure rod 18 presses down the second connecting frame 22 through the fourth axis 21. The second connecting frame 22 drives the lifting plate 23, and the lifting plate 23 drives the force column 25. When the force column 25 contacts the pipeline body 4, the lifting plate 23 drives the pressure sensor 26 to continue to move downward, so that the top of the force column 25 contacts the detection end of the pressure sensor 26, thereby achieving the purpose of detecting the pressure value applied by the force column 25 to the pipeline body 4, and transmitting the detection data to the inside of the controller 28. When the pipeline body 4 is deformed, the user observes the maximum pressure through the controller 28 to obtain the maximum pressure value that the pipeline body 4 can withstand.

[0035] The user can unscrew the hexagon socket bolt 34, reverse the direction of the two-way stepped positioning claw 32, and then put it on the outer surface of the limit block 33, and finally fix it to the moving block 31 through the hexagon socket bolt 34, which greatly increases the maximum value range of the pipe body 4 diameter that can be clamped by the device and improves its practicality.
