Detailed Embodiment

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0017] Embodiment: As Figures 1-4As shown in the figure, the utility model provides an internal thread detection device for oil pipelines, which includes a bottom plate 1. On one side of the top end of the bottom plate 1, there is a fixed plate 21. On one side of the top end of the fixed plate 21, a first motor 22 is fixedly installed. In the middle of the fixed plate 21, a first screw rod 24 is rotatably installed. One end of the first screw rod 24 is fixedly installed at the driving end of the first motor 22. In the middle of the top end of the fixed plate 21, there is a moving plate 25. In the middle of the bottom end of the moving plate 25, a moving block 241 is fixedly installed. The middle part of the moving block 241 is threadedly installed on the outer surface of the middle part of the first screw rod 24. On the top end of the moving plate 25, a second motor 26 is fixedly installed. On one side of the second motor 26, there is a detection device body 27. One side of the detection device body 27 is fixedly installed at the driving end of the second motor 26. On the other side of the top end of the bottom plate 1, a placing table 3 is fixedly installed. In the middle of the top end of the placing table 3, there is an oil pipeline body 4.

[0018] On the upper part of the placing table 3, two mirror-image distributed double-headed screw rods 31 are rotatably installed. On the outer surfaces of the two double-headed screw rods 31, two mirror-image distributed sliding blocks 32 are threadedly installed. On the top ends of the four sliding blocks 32, clamping blocks 33 are fixedly installed.

[0019] On the top end of the fixed plate 21, two mirror-image distributed limiting blocks 23 are fixedly installed. On the bottom end of the moving plate 25, four evenly distributed sliding blocks 231 are fixedly installed. The four sliding blocks 231 are all slidably clamped on the outer surface of the upper part of the limiting blocks 23. By setting the limiting blocks 23, the sliding blocks 231 are limited by the limiting blocks 23, so that when the first screw rod 24 rotates to drive the moving plate 25 to move, it is more stable.

[0020] On one side of the top end of the bottom plate 1, a protective cover 2 is fixedly installed. The fixed plate 21 is fixedly installed in the middle of the protective cover 2. By setting the protective cover 2, the detection device body 27, the first motor 22 and the second motor 26 can be protected.

[0021] On the upper part of the placing table 3, two mirror-image distributed sliding grooves 311 are opened. The four sliding blocks 32 are all slidably clamped inside the sliding grooves 311. By setting the sliding grooves 311, when the double-headed screw rods 31 rotate to drive the sliding blocks 32 to move, the sliding blocks 32 are limited by the sliding grooves 311, so that when the clamping blocks 33 move relatively to clamp and fix the oil pipeline body 4, it is more stable.

[0022] One end of the two double-headed screw rods 31 passing through the placing table 3 is fixedly installed with a handle 34. By setting the handle 34, rotating the handle 34 drives the double-headed screw rods 31 to rotate, so that the two clamping blocks 33 move relatively, and thus the oil pipeline body 4 can be clamped and fixed.

[0023] At the four corners of the bottom end of the bottom plate 1, bases 11 are fixedly installed. By setting the bases 11, the whole device can be supported.

[0024] A plurality of uniformly distributed mounting holes 111 are provided in the upper parts of the four bases 11. By providing the mounting holes 111, the bases 11 can be fixed by bolts, making the whole device more stable.

[0025] Working principle: During actual use, driven by the second motor 26, the detection device body 27 is driven to rotate. At the same time, the first motor 22 is started to drive the first screw rod 24 to rotate, thereby driving the moving block 241 threadedly mounted on the outer surface of the first screw rod 24 to move, that is, driving the moving plate 25 to move, and further driving the second motor 26 and the detection device body 27 to move into the interior of the oil pipeline body 4, so as to detect the internal thread of the oil pipeline body 4 while the detection device body 27 rotates and moves.

[0026] When fixing the oil pipeline body 4, the oil pipeline body 4 is placed at the middle of the top of the placing table 3. By rotating the handle 34 to drive the double-headed screw rod 31 to rotate, the two sliding blocks 32 threadedly mounted on the outer surface of the double-headed screw rod 31 move relatively, thereby driving the two clamping blocks 33 to move relatively, so as to clamp and fix the oil pipeline body 4, avoiding shaking during detection and resulting in inaccurate detection results.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these changes and modifications.
