DETAILED DESCRIPTION

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 4 As shown, a pipeline flaw detection and positioning device provided by an embodiment of the utility model includes a flaw detection and positioning instrument 1 and an adjustment shell 2, the front side of the adjustment shell 2 is fixedly connected to the rear side of the flaw detection and positioning instrument 1, the inner cavity of the adjustment shell 2 is movably connected to a device shell 3, the front side of the inner cavity of the device shell 3 is movably connected to a control block 4 through a rotating shaft, the rear side of the control block 4 penetrates the device shell 3 and extends to the outside of the inner cavity of the device shell 3, and the inner cavity of the device shell 3 is provided with a limiting device 5.

[0022] refer to Figure 4 The limiting device 5 includes two limiting shells 501, and the opposite sides of the two limiting shells 501 penetrate the device shell 3 and extend to the outside of the inner cavity of the device shell 3. The inner cavity of the device shell 3 is fixedly connected with two stabilizing blocks 502 used in conjunction with the limiting shells 501. The surface of the stabilizing blocks 502 is movably connected to the inner cavity of the limiting shell 501. The opposite sides of the two stabilizing blocks 502 are fixedly connected with springs 503, and the opposite sides of the two springs 503 are fixedly connected to the inner cavity of the limiting shell 501.

[0023] The above solution is adopted: by providing the limiting device 5 , when the movable clamp 12 moves to a suitable position, the limiting device 5 has a limiting effect on the position of the movable clamp 12 .

[0024] refer to Figure 4 The surface of the control block 4 is fixedly connected with an extrusion block 6, and the rear side of the limiting shell 501 is fixedly connected with an extrusion column 7 used in conjunction with the extrusion block 6, and the surface of the extrusion block 6 is in contact with the surface of the extrusion column 7.

[0025] The above scheme is adopted: by setting the extrusion block 6 and the extrusion column 7, when the control block 4 rotates, it will drive the extrusion block 6 to rotate along the surface of the extrusion column 7. The extrusion force of the extrusion block 6 on the extrusion column 7 can drive the two extrusion columns 7 to move toward each other. When the extrusion column 7 moves, it can drive the limit shell 501 to move.

[0026] refer to Figure 4 Two limiting grooves 8 for use with the limiting shell 501 are provided on the left and right sides of the inner cavity of the adjusting shell 2 , and the surface of the limiting shell 501 contacts the inner cavity of the limiting grooves 8 .

[0027] The above scheme is adopted: by setting the limit groove 8, when the device shell 3 moves to the appropriate position, the control block 4 is released, and the restoring force generated by the spring 503 restoring its shape will drive the limit shell 501 to be stuck into the inner cavity of the limit groove 8. The coordinated use of the limit shell 501 and the limit groove 8 has a limiting effect on the position of the device shell 3.

[0028] refer to Figure 4 The left and right sides of the device shell 3 are fixedly connected with sliders 9, and the left and right sides of the adjustment shell 2 are provided with slide grooves 10 used in conjunction with the sliders 9, and the surface of the slider 9 is movably connected with the inner cavity of the slide groove 10.

[0029] The above solution is adopted: by setting the slider 9 and the slide groove 10, when the device shell 3 moves, the slider 9 will be driven to move along the inner cavity of the slide groove 10. The coordinated use of the slider 9 and the slide groove 10 has a limiting effect on the moving position of the device shell 3.

[0030] refer to Figure 3 A winding drum 11 is fixedly connected to the rear side of the flaw detection locator 1. A cable is sleeved on the surface of the winding drum 11. A plug is arranged on the right side of the cable, and a detection head is arranged on the left side of the cable.

[0031] The above solution is adopted: by providing the winding drum 11, the setting of the winding drum 11 can conveniently store the cables so that the cables will not be tangled and knotted due to clutter.

[0032] refer to Figure 2 A mobile clamp 12 is fixedly connected to the bottom of the device shell 3, and a fixed clamp 13 used in conjunction with the mobile clamp 12 is fixedly connected to the rear side of the flaw detection locator 1. The rear side of the fixed clamp 13 contacts the front side of the mobile clamp 12, and the cable passes through the inner cavities of the fixed clamp 13 and the mobile clamp 12, and extends to the outside of the inner cavities of the fixed clamp 13 and the mobile clamp 12.

[0033] The above solution is adopted: by providing the movable clamp 12 and the fixed clamp 13, the coordinated use of the fixed clamp 13 and the movable clamp 12 has a limiting effect on the positions of the cable, the detection head and the plug.

[0034] The working principle of this utility model:

[0035] During use, when it is necessary to conveniently store the detection head, plug and cable used in the pipeline flaw detector locator 1, the user first moves the plug to the bottom of the fixing clamp 13, and drives the cable to move into the inner cavity of the fixing clamp 13, and then winds the cable around the surface of the winding reel 11. After the cable is wound, the other end of the cable is placed in the inner cavity of the fixing clamp 13, and the detection head is driven to move to the bottom of the fixing clamp 13. Then, the control block 4 is rotated to drive the control block 4 to rotate through the rotating shaft. When the control block 4 rotates, it will drive the extrusion block 6 to rotate along the surface of the extrusion column 7. The extrusion block 6 will generate an extrusion force on the extrusion column 7. The two extrusion columns 7 subjected to the extrusion force will move closer to each other. When the extrusion column 7 moves, it will drive the limit shell 501 to move along the surface of the stabilizing block 502. When the limit shell 501 moves The force generated causes the spring 503 to undergo elastic deformation. When the limit shell 501 disengages from the limit groove 8 located at the top of the inner cavity of the adjusting shell 2, the device shell 3 is pulled toward the side close to the cable. When the device shell 3 moves, it drives the slider 9 to move along the inner cavity of the slide groove 10, and at the same time drives the movable clamp 12 to move toward the side close to the fixed clamp 13. When the rear side of the fixed clamp 13 contacts the front side of the movable clamp 12, the control block 4 is released, and the restoring force generated by the spring 503 restoring its shape will drive the limit shell 501 to be clamped into the inner cavity of the limit groove 8. The coordinated use of the limit shell 501 and the limit groove 8 has a limiting effect on the position of the movable clamp 12. The coordinated use of the fixed clamp 13, the movable clamp 12 and the winding reel 11 has a limiting effect on the position of the cable, the detection head and the plug. At this time, the detection head, the plug and the cable used by the pipeline flaw detection locator 1 are conveniently stored.

[0036] In summary, the pipeline flaw detection and positioning device solves the problem that the existing pipeline flaw detection and positioning instrument is a device for detecting internal defects or damage of pipelines, and is usually used for pipeline detection and maintenance work in the industrial field. When in use, the plug needs to be connected to the flaw detection and positioning instrument, and then the detection head is used to detect the pipeline. The plug and the detection head are connected by a cable. The cable, the detection head and the plug are easy to be entangled with each other when not in use, making it difficult to use them again, and the cable is easy to be damaged. If it is not stored, it is easy to lose it. However, the existing pipeline flaw detection and positioning instrument does not have a component for conveniently storing the detection head, plug and cable used.
