Technical Field

[0001] This invention relates to the field of pipeline inspection device technology, specifically a sensor-based pipeline inspection device. Background Technology

[0002] After pipeline manufacturing, the roughness of the inner wall of the pipe needs to be inspected. The conventional inspection device is a rapid inspection method based on roughness detection sensors. Existing inspection devices install multiple roughness detection sensors and then slowly move them along the inner wall of the pipe. However, the roughness detection sensors are prone to misalignment during the movement, and the method of using multiple roughness detection sensors still has omissions. Usually, multiple inspections are required to obtain accurate inspection results. In order to address the above problems, the inventor proposes a sensor-based pipeline inspection device to solve the above problems. Summary of the Invention

The corner block is driven and connected to an adjustable detection mechanism. The adjustable detection mechanism is slidably connected to the main shaft. The moving component is threaded to move the tube body. The adjustable detection mechanism is moved manually along the inner wall of the tube body for detection. The adjustment device makes multiple corner blocks slide into the rotating ring, so that the guide wheel assembly and the adjustable detection mechanism can fit against the inner wall of the tube body. The guide wheel assembly makes it easy for the entire detection device to move inside the tube body. The rotating drive device drives the rotating ring and the adjustable detection mechanism to rotate together inside the tube body, thereby detecting the roughness of the inner wall of the tube body.

[0005] Preferably, the rotary drive device includes a second motor, the second motor is fixedly connected to an L-shaped block, the L-shaped block is fixedly connected to a fixed base, the output end of the second motor is provided with a gear, the gear drives a rotating ring, the second motor is fixedly installed on the fixed base and rotates through the gear drive of the rotating ring; both ends of the pipe body are provided with flanges, one of the flanges is threadedly connected to a moving component, the moving component is fixedly connected to the pipe body; the moving component includes a connecting plate, the connecting plate is threadedly connected to the flange, a push rod is movably inserted in the connecting plate, one end of the push rod is fixedly connected to a round seat, the side of the round seat is fixedly connected to an adjustment device, the connecting plate is fixedly installed, and then the adjustable detection mechanism is manually rotated in the pipe body by pushing the push rod.

[0006] Preferably, the adjusting device includes a first motor, which is fixedly mounted on the side of the circular base. A lead screw is provided at the output end of the first motor. A connecting sleeve is fixedly connected to the first motor, and a spline sleeve is fixedly connected to the connecting sleeve. The spline sleeve is fixedly connected to a fixed base. A spline shaft is slidably engaged within the spline sleeve. The lead screw is threadedly connected to the spline shaft. One end of the spline shaft is rotatably connected to a main shaft. The first motor causes the spline shaft to slide along the spline sleeve via the lead screw, enabling the corner block to slide, and the rotating ring can rotate on the outer surface of the spline shaft. A gear ring is fixedly provided on the outer surface of the rotating ring, meshing with a gear. An annular groove is formed on one side surface of the rotating ring, and a fixed base is rotatably connected within the annular groove. Multiple angular grooves are formed on the other side surface of the rotating ring. The corner block is slidably connected within the angular groove. Multiple inner guide grooves are provided on the inner wall of the rotating ring. The main shaft is slidably connected within these inner guide grooves. The gear drive ring and rotating ring rotate together along the fixed base without affecting the sliding of the corner block along the angular grooves on the rotating ring.

Multiple fixing blocks are fixedly provided on the outer surface of the rotating shaft. These fixing blocks movably pass through the inner guide grooves and are fixedly connected to the corner block.

[0007] Preferably, a second convex groove is formed on the inclined surface of the corner block. A push rod is slidably engaged in the second convex groove. The push rod movably passes through the rotating ring and is connected to the guide wheel assembly. A convex slider is fixed on the corner block and slidably disposed in the first convex groove. A pull shaft is fixed on the convex slider and is connected to an adjustable detection mechanism. A second spring is fixed at one end of the pull shaft, and one end of the second spring is fixed to the inner wall of the first convex groove. When the corner block slides into the corner groove, the push rod can be driven through the second convex groove. The guide wheel assembly moves to the inner wall of the tube, while the convex slider on the corner block slides along the first convex groove, enabling the adjustable detection mechanism to operate via a pull shaft drive. The guide wheel assembly includes a U-shaped seat, which is fixedly connected to a top rod. Cross grooves are formed on both sides of the U-shaped seat, and cross blocks slide within the cross grooves.

The second hinge seat is fixedly sleeved on the outer surface of the pull shaft. Multiple fixing strips are fixedly disposed on the inner wall of the adjusting ring. The fixing strips are fixedly connected to the outer surface of the main shaft. When the corner block slides into the corner groove, the pull shaft drives the second hinge seat to slide along the first convex groove. The first hinge seat is also driven to slide along the convex groove towards the outer ring of the adjusting ring through multiple pull rods. This causes the guide rod to push the roughness detection sensor to the inner wall of the tube body to detect the roughness of the inner wall of the tube body. The roughness detection sensor model can be selected from Zhongce TS.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] 1. The device is fixedly installed by the tube body and the connecting plate. Then, the entire detection device is rotated in the tube body by manually pushing the push rod. When the first motor moves the spline shaft through the screw drive, the corner block slides into the corner groove opened in the rotating ring. The rotating wheel is moved to the inner wall of the tube body through the push rod drive, so that the entire detection device can move stably along the inner wall of the tube body.

[0010] 2. As the corner block slides into the corner groove, it can move multiple pull rods through the pull shaft, which in turn causes the guide rod to push the roughness detection sensor to the inner wall of the tube. Then, the second motor drives the gear ring, rotating ring and roughness detection sensor to rotate along the inner wall of the tube, thereby performing roughness detection on the inner wall of the tube around its circumference.

[0035] By adopting the above technical solution, the main shaft 8 rotates together with the rotating ring 42, and when the lead screw 311 causes the spline shaft 35 to slide along the spline sleeve 34, it can cause the rotating shaft 82 to move along one end of the main shaft 8, and drive the corner block 9 to slide through multiple fixed blocks 83.

[0036] A second convex groove 91 is provided on the inclined surface of corner block 9. A top rod 92 is slidably engaged in the second convex groove 91.

[0039] By adopting the above technical solution, the rotating wheel 62 inside the U-shaped seat 61 driven by the push rod 92 moves to the inner wall of the tube body 1, and causes the first spring 63 on the cross block 64 to deform, so that the entire detection device can move stably along the inner wall of the tube body 1.

[0040] The adjustable detection mechanism 7 includes an adjusting ring 71. A plurality of convex grooves 711 are formed on one side surface of the adjusting ring 71. A first hinge seat 75 is slidably provided in the convex grooves 711. A guide rod 73 is fixedly connected to the first hinge seat 75.

[0041] By adopting the above technical solution, when the corner block 9 slides into the corner groove 422, the pull shaft 931 drives the second hinge seat 77 to slide along the first convex groove 81, and through multiple pull rods 76 drives the first hinge seat 75 to slide along the convex groove 711 towards the outer ring of the adjusting ring 71, thereby causing the guide rod 73 to push the roughness detection sensor 74 to move to the inner wall of the tube body 1 to detect the roughness of the inner wall of the tube body 1. The roughness detection sensor 74 can be a Zhongce TS1100 model.

[0042] Working principle: The connecting plate 21 is fixed to the flange 11 at one end of the pipe body 1 using bolts. Then, the adjustable detection mechanism 7 is moved and detected inside the pipe body 1 by manually using the push rod 22. The first motor 31 drives the lead screw 311 to rotate. When the lead screw 311 causes the spline shaft 35 to slide along the spline sleeve 34, it can move the rotating shaft 82 along one end of the main shaft 8. The rotating shaft 82 drives the corresponding corner block 9 to slide into the corner groove 422 through multiple fixed blocks 83. The corner block 9 can move the top rod 92 to drive the rotating wheel 62 in the U-shaped seat 61 to the inner wall of the pipe body 1 through the second convex sliding groove 91 opened at the inclined surface, and deform the first spring 63 on the cross block 64. Thus, when moving the entire detection device, it can move quickly and stably inside the pipe body 1. The corner block 9 slides into the corner groove 422. When the corner block 9 is in the groove 422, the convex slider 93 on the corner block 9 slides along the first convex groove 81 and can drive the second hinge seat 77 to slide along the first convex groove 81 through the pull shaft 931. It can also drive the first hinge seat 75 to slide along the convex groove 711 towards the outer ring of the adjusting ring 71 through multiple pull rods 76. Then, the guide rod 73 pushes the roughness detection sensor 74 to move to the inner wall of the tube body 1. Then, the second motor 51 drives the gear ring 43 and the rotating ring 42 to rotate through the gear 52. While the rotating ring 42 rotates along the fixed seat 41 through the annular groove 421, it will not interfere with the corner block 9 sliding into the corner groove 422 of the rotating ring 42. The rotating ring 42 drives the main shaft 8, the adjusting ring 71 and the roughness detection sensor 74 to rotate. Then, the roughness detection sensor 74 detects the roughness of the inner wall of the tube body 1 around the circumference.
