DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figure 1-5 , the utility model provides a technical solution:

[0027] Embodiment 1: A pressure pipe wall thickness detection flaw detection device, including a top plate 1 and a workbench 25, the top of the top plate 1 is fixedly connected to an electric push rod 2, the output end of the electric push rod 2 is fixedly connected to a connecting frame 3, the other end of the connecting frame 3 is fixedly connected to a connecting block 4, the bottom of the connecting block 4 is fixedly connected to a clamping block 5, the top of the top plate 1 is fixedly connected to three slide rails 6, the inner wall of the connecting block 4 is rotatably connected to a rotating rod 7, the other end of the rotating rod 7 is fixedly connected to a triangular plate 8, and the inside of the triangular plate 8 is rotatably connected to a fixed column 9, and the fixed column 9 is fixedly connected to the top plate 1, and the two corners of the triangular plate 8 are rotatably connected to the rotating rod 1 2. The other end of the rotating rod 2 12 on both sides is rotatably connected with a connecting block 2 13. The bottom of the connecting block 2 13 on both sides is fixedly connected with a clamping block 2 14. At the same time, the connecting block 14 and the top of the connecting block 2 13 are fixedly connected with a bracket 10. The outer walls of the brackets 10 on both sides are provided with a clamping plate 11. The slide rails 6 are in a triangular array, and the clamping block 15 corresponds to one of the slide rails 6. At the same time, the clamping block 15 is slidably connected to the slide rail 6, and the clamping block 2 14 is slidably connected to the two corner slide rails 6. The inner wall of the bracket 10 is fixedly connected with a pair of springs 15. At the same time, the clamping plate 11 is fixedly connected to the other end of the spring 15, and the outer wall of the clamping plate 11 is fixedly connected with a cushion 16.

[0028] The pressure pipe is sleeved on the outside of the three clamping plates 11, and then the electric push rod 2 is started, which drives the movement of the connecting block 14 by pushing the connecting frame 3 forward and backward. The connecting block 14 keeps the same direction on the slide rail 6 through the limiting action of the clamping block 15. When the connecting block 14 moves forward, it will drive the rotating rod 17 to rotate and straighten the rotating rod 17. When the rotating rod 17 is straightened, the rotating rods 2 12 on the other two corners are driven to straighten through the triangular plate 8, and the connecting block 2 13 will move outward with the connecting block 14. The outward movement of the connecting block 14 and the connecting block 2 13 will drive the clamping plate 11 on the bracket 10 to move, and start to clamp and fix the pressure pipe. When clamping and fixing the pressure pipe, the elasticity of the spring 15 and the softness of the cushion 16 play a role in protecting the inner diameter of the pressure pipe and preventing it from being damaged. Their cooperation makes it possible to quickly fix the pressure pipes with different inner diameters, thereby improving work efficiency. Through this design, the installation and fixing of the pressure pipe becomes more convenient and efficient.

[0029] Embodiment 2: The top of the workbench 25 is fixedly connected to a fixing frame 18, and an adjustment component is arranged outside the fixing frame 18, and the adjustment component includes a threaded rod 20 and a slider 21, and the slider 21 is threadedly connected to the outer wall of the threaded rod 20, and the top wall of the fixing frame 18 is fixedly connected to an electric hydraulic rod 24, and the output end of the electric hydraulic rod 24 is fixedly connected to a fixing plate 19, and a pair of positioning rods 22 are fixedly connected to the inner wall of the fixing plate 19, and the slider 21 is slidably connected to the positioning rods 22, and a detection probe 23 is fixedly connected to the bottom of the slider 21, and the threaded rod 20 is rotatably connected in the fixing plate 19, and at the same time, the top of the fixing plate 19 A pair of limit rods 17 are fixedly connected on both sides, and the limit rods 17 pass through the fixed frame 18 and are slidably connected to the inside of the fixed frame 18. A mounting plate 26 is fixedly connected to the outer wall of the workbench 25, and a motor 27 is fixedly connected to the top wall of the mounting plate 26. A rotating shaft 28 is fixedly connected to the output end of the motor 27. The rotating shaft 28 passes through the mounting plate 26 and extends to the inside of the workbench 25. A gear 1 29 is fixedly connected to the bottom wall of the rotating shaft 28. At the same time, a support column 30 is fixedly connected to the top center of the workbench 25, and a gear 2 31 is fixedly connected to the outer wall of the support column 30, and the gear 2 31 is meshed with the gear 1 29.

[0030] By rotating the threaded rod 20, the slider 21 will move forward and backward for adjustment, and the moving direction will be positioned on the positioning rod 22. When the slider 21 moves, the detection probe 23 will approach the edge of the pressure pipe and begin to detect its wall thickness. After starting the electric hydraulic rod 24, the fixed plate 19 and the detection probe 23 will be adjusted up and down. The fixed plate 19 ensures that its up and down moving directions are consistent through the limiting effect of the limiting rod 17, thereby realizing the detection of the upper and lower positions of the pressure pipe. Starting the motor 27 on the mounting plate 26 will drive the gear 1 29 on the rotating shaft 28 to rotate, and then drive the gear 2 31 meshed with it to rotate. This will cause the top plate 1 on the support column 30 to rotate, thereby causing the pressure pipe to rotate. These coordinations make the detection of the pressure pipe more comprehensive, improve work efficiency and the reliability of monitoring data.

[0031] When working, the pressure pipe wall thickness detection and flaw detection device is a device used to detect and flaw the wall thickness of the pressure pipe. It usually includes various sensors, detectors and measuring instruments, which are used to detect the thickness of the pipe wall and possible cracks, corrosion or other defects. First, the pressure pipe is sleeved on the outside of the three clamping plates 11, and then the electric push rod 2 is started. Under the action of the electric push rod 2, the connecting frame 3 is pushed forward and backward. At this time, the connecting frame 3 drives the connecting block 4 to move under the action of the thrust. The connecting block 4 moves on the slide rail 6 through the limiting action of the clamping block 5 and keeps the same direction. When the connecting block 4 moves forward, it will drive the rotating rod 7 to rotate and promote The rotating rod 1 7 is in a straightened state. When the rotating rod 1 7 is straightened, the rotating rods 2 12 on the other two corners will be driven to straighten through the triangular plate 8. At this time, the two corner connecting blocks 2 13 will follow the connecting block 1 4 to move outward. When the connecting blocks 1 4 and 13 move outward, the clamping plate 11 on the bracket 10 will move and start to clamp and fix the inner diameter of the pressure pipe. When clamping and fixing the pressure pipe, the elasticity of the spring 15 and the softness of the cushion 16 are used to protect the inner diameter of the pressure pipe from damage. Through their cooperation, the pressure pipe is protected from damage. The pressure pipes with different inner diameters can be quickly fixed, which improves the work efficiency. After the fixing is completed, by rotating the threaded rod 20, when the threaded rod 20 rotates, the slider 21 will be driven to move forward and backward for adjustment, and the moving direction will be positioned on the positioning rod 22. When the slider 21 moves, the detection probe 23 will be driven to move and approach the edge of the pressure pipe, and the wall thickness of the pressure pipe will be detected at the same time. In conjunction with the start of the electric hydraulic rod 24, the fixing plate 19 and the detection probe 23 will be pushed up and down for adjustment. At the same time, the fixing plate 19 is limited by the limiting rod 17, so that the fixing plate 19 moves up and down in the same direction, so that the upper and lower positions of the pressure pipe can be detected. At this time, the motor 27 on the starting mounting plate 26 is driven to rotate the gear 1 29 on the rotating shaft 28 under the action of the motor 27, and the meshing gear 2 31 will be driven to rotate, thereby driving the top plate 1 on the support column 30 to rotate, and the pressure pipe will rotate. The cooperation between them makes the pressure pipe more comprehensive during detection, improves the work efficiency and the reliability of the monitoring data.
