Example 2

[0019] Based on Embodiment 1, a preferred embodiment of the drill pipe joint defect detection device provided by this utility model is available for reference. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The inner wall of the movable frame 7 is connected to a reciprocating lead screw 9, one end of which is connected to a driven conical wheel 10. A slider 11 is connected to the surface of the reciprocating lead screw 9, and a lever 13 is connected to the surface of the slider 11. A support frame 14 is connected to the inner wall of the movable frame 7 above the slider 11. A movable block 15 is connected to the surface of the support frame 14, and a second probe 16 is connected to the bottom of the movable block 15. A fixed conical wheel 17 is connected to the surface of the motor box 5. Through the arrangement of the reciprocating lead screw 9, driven conical wheel 10, slider 11, guide rail 12, lever 13, support frame 14, movable block 15, second probe 16, and fixed conical wheel 17, it is convenient to perform different heights and angles of the drill pipe joint surface, further improving the detection range and thus solving the problem of inaccurate detection data.

[0020] Preferably, the inner wall of the movable frame 7 is connected to a guide rail 12 near the lower part of the slider 11. The guide rail 12 is distributed in a "U" shape, which facilitates the sliding guidance of the slider 11.

[0021] Preferably, the driven cone wheel 10 meshes with the fixed cone wheel 17, and the size of the driven cone wheel 10 is smaller than that of the fixed cone wheel 17, which facilitates the driven cone wheel 10 to rotate on its own axis while revolving around the fixed cone wheel 17.

[0022] Preferably, the movable frame 7 and the fixed conical wheel 17 form a rotating structure, and the movable frame 7 is distributed in a "U" shape, which facilitates the rotation of the movable frame 7 around the fixed conical wheel 17.

[0023] Preferably, the slider 11 is connected to the support frame 14 via the lever 13, and the movable block 15 is arranged in a "U" shape in side view. The movable block 15 has grooves on both sides that cooperate with the lever 13, which facilitates the slider 11 to rotate the movable block 15 via the lever 13 when sliding.

[0024] Preferably, the support frame 14 includes two fixed blocks connected by a pin, and the movable block 15 is rotatably connected to the support frame 14 via the pin, which facilitates the support of the movable block 15.

[0025] Preferably, a connecting frame is provided on the top of the fixed cone wheel 17, and the fixed cone wheel 17 is connected to the surface of the motor box 5 through the connecting frame. The connecting frame is distributed in a "+" shape when viewed from above, which facilitates the support of the fixed cone wheel 17.

[0026] The process of using the drill pipe joint defect detection device provided by this utility model is as follows: First, start the hydraulic cylinder 4, so that the hydraulic cylinder 4 drives the motor box 5 to descend, so that the motor box 5 drives the first probe 8 to descend. At this time, start the motor box 5, so that the drive shaft 6 drives the first probe 8 to rotate through the movable frame 7, which is conducive to the detection of the inner side of the drill pipe joint at different heights and angles.

[0027] Meanwhile, when the movable frame 7 rotates, the reciprocating screw 9 drives the driven cone wheel 10 to revolve around the fixed cone wheel 17, thereby causing the driven cone wheel 10 to rotate simultaneously. This rotation of the reciprocating screw 9 then drives the slider 11 to slide back and forth under the guidance of the guide rail 12. The slider 11 then drives the movable block 15 to rotate back and forth at a certain angle via the lever 13. This causes the movable block 15 to drive the second probe 16 to perform multi-range detection, effectively improving the detection range and further enhancing the accuracy of the detection data.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
