[0022] In this embodiment, the inner arc surface of the pressure plate 2 is adapted to the outer side of the main body 1, and the fixed support member 4 is inserted on the main body 1 and there are four groups in total. The main body 1 can be kept relatively stable in the pipe 3 through the fixed support member 4; the outer ring of the bearing 13 is fixedly embedded in the top of the fixed support member 4, the screw 6 passes through the main body 1 and is threadedly connected to the main body 1, one end of the screw 6 is fixed in the inner ring of the bearing 13, and the first rotating wheel 5 is rotatably installed at the bottom of the fixed support member 4 through the rotating rod 14, and the installation structure of each group of fixed support members 4 is consistent; the first detection component 7 and the second detection component 9 are both inserted on the main body 1, and there are several groups of the first detection component 7 and the second detection component 9, and the second rotating wheel 8 is rotatably installed at the bottom of the first detection component 7, and each group of the second detection component 9 is sleeved A detection sheath 12 is provided, and a scale 11 is engraved on each group of first detection components 7; a group of second detection components 9 is respectively arranged on both sides of each group of first detection components 7, and a magnetic ball 10 is rotatably installed at the bottom of the second detection component 9. The magnetic ball 10 is specifically cast as a strong magnet. Through the first detection component 7 and the second detection component 9, it is convenient to detect whether there is a depression or bulge on the corresponding pipeline 3; the rotating rod 14 is fixedly connected to the center position of both sides of the first rotating wheel 5, and the anti-slip jacket 15 is fixedly mounted on the first rotating wheel 5. The anti-slip jacket 15 can ensure the stability of the contact between the first rotating wheel 5 and the second rotating wheel 8 and the main body 1 to prevent deviation; the first rotating wheel 5 and the second rotating wheel 8 have the same structure and installation, and the anti-slip jacket 15 is specifically made of rubber.

[0023] The working principle and use process of the utility model are as follows: in actual use, the two ends of the pipe 3 to be inspected are erected by corresponding supporting devices, and the main body 1 is sleeved in the corresponding pipe 3 to be inspected, and the screw rod 6 is adjusted and rotated clockwise. Since the screw rod 6 is threadedly connected to the main body 1, the screw rod 6 gradually descends during the rotation and brings the fixed support member 4 close to the corresponding pipe 3 until the first rotating wheel 5 is close to the pipe 3. The four groups of fixed support members 4 are adjusted in the same way to keep the main body 1 relatively stable in the pipe 3 without offset. Then, pressure can be directly applied to the first detection component 7 and the second detection component 9 on the main body 1 through the arc-shaped pressure plate 2, so that the first detection component 7 and the second detection component 9 are extended into the main body 1 until the second rotating wheel 8 and the magnetic ball 10 are close to the pipe 3, and the detection sheath 12 is sleeved on the second detection component 9 and contacts the main body 1, and then the main body 1 can be pushed forward, and the main body 1 moves smoothly on the pipe 3 through the first rotating wheel 5 at the bottom of the fixed support member 4. If a depression appears on the outside of the pipe 3 during the process, the magnetic ball 10 The adsorption effect between the magnetic ball 10 and the metal pipe 3 can make the magnetic ball 10 always close to the outside of the pipe 3 (including the concave surface). When passing through the concave, the second detection component 9 extends into the main body 1 for a certain distance, and the extending distance depends on the depth of the concave. At this time, the detection sheath 12 will change its position on the second detection component 9 as the second detection component 9 changes. After passing through the concave position, the second detection component 9 returns to its original position. After the detection is completed, the distance between the detection sheath 12 and the main body 1 can be checked to determine whether there is a concave in the pipe 3, and the depth of the concave can be directly known. If a bulge appears on the pipe 3, the first detection component 7 will be lifted up and will not be restored when passing through the bulge position. After the detection is completed, the position of the scale 11 on the first detection component 7 corresponding to the main body 1 before the detection and the position of the scale 11 on the first detection component 7 corresponding to the main body 1 after the detection can be compared to determine whether there is a bulge on the pipe 3 and the height of the bulge on the pipe 3. A complete straightness detection can be performed. The overall detection device is similar to the caliber of the pipe 3, can be carried easily, and is not restricted in the use position.
