[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a pressure pipeline inspection and testing device, including a positioning seat 1; a motor 3 is provided on one side of the positioning seat 1, a cylinder 18 is provided on one side above the positioning seat 1, and a detector 20 is provided on one side of the cylinder 18; it also includes: a connecting frame 2 is fixedly connected to one side of the top of the positioning seat 1, a threaded rod 4 is rotatably connected to the middle of the connecting frame 2, a threaded block 5 is threadedly connected to the outer side of the threaded rod 4, and a lifting groove 6 is provided on one side of the threaded block 5; the upper end of the threaded rod 4 passes through the connecting frame 2 and is fixedly connected to the output end of the motor 3, and the lifting groove 6 is opened on the side of the connecting frame 2 near the positioning seat 1, so as to provide power for the movement of the threaded block 5 through the threaded rod 4, thereby facilitating the lifting and lowering of the connecting rod 7 driven by the threaded block 5.

[0031] One end of the threaded block 5 is fixedly connected to a connecting rod 7, and a buffer spring 12 is fixedly connected to the bottom of the connecting rod 7. A limit groove 8 is formed on one side of the upper end of the connecting rod 7, and a limit rod 9 is fixedly connected in the middle of the limit groove 8. A limit block 10 is slidably connected to the outer side of the limit rod 9, and a pressing block 11 is fixedly connected to one side of the limit block 10. One end of the threaded block 5 passes through the lifting groove 6 and is fixedly connected to the connecting rod 7. The pressing block 11 is slidably connected to one side of the connecting frame 2. A groove is formed in the middle of the upper end of the pressing block 11, and the two sides of the limit block 10 are connected to the limit rod 10. The upper end of the pressing block 11 is fixedly connected to the inner side, and the bottom of the buffer spring 12 is fixedly connected to the bottom surface of the groove of the pressing block 11. By setting the buffer spring 12, the limiting groove 8, the limiting rod 9 and the limiting block 10 between the connecting rod 7 and the pressing block 11, it is easy to achieve buffering between the connecting rod 7 and the pressing block 11, thereby reducing the damage of the pressing block 11 to the pressure pipeline. Moreover, by pressing the pressure pipeline with the pressing block 11, it is easy to achieve rapid positioning of the pressure pipeline, making the inspection and testing of the pressure pipeline more convenient and faster.

[0032] The positioning base 1 has a lower rotating rod 13 rotatably connected to one side of its top surface. A rotating shaft 14 is rotatably connected to the upper end of the lower rotating rod 13. A torsion spring 15 is sleeved on the outer side of the rotating shaft 14. An upper rotating rod 16 is rotatably connected to the other side of the rotating shaft 14. An upper positioning frame 17 is rotatably connected to the upper end of the upper rotating rod 16. A mounting bracket 19 is provided on one side of the upper positioning frame 17. The lower rotating rod 13, rotating shaft 14, torsion spring 15, and upper rotating rod 16 are symmetrically arranged on both sides of the pressing block 11. The mounting bracket 19 is fixedly connected to the positioning base 1. On one side of the top surface, cylinder 18 and detector 20 are fixedly connected to the bottom surface of the upper end of mounting bracket 19. Cylinder 18 is symmetrically arranged on both sides of detector 20. The lower end of cylinder 18 is fixedly connected to the top surface of upper positioning bracket 17, and the lower end of detector 20 is slidably connected to the middle of upper positioning bracket 17. The lifting and lowering of upper positioning bracket 17 is adjusted by cylinder 18, which facilitates the adjustment of the extension and retraction of upper rotating rod 16 and lower rotating rod 13, thereby facilitating the stable clamping of pressure pipeline and the stable inspection and testing of pressure pipeline.

[0033] Working principle: When using this pressure pipeline inspection and testing device, firstly, the pressure pipeline is sleeved on the outside of the pressing block 11, and the threaded rod 4 is rotated in the middle of the connecting frame 2 by controlling the motor 3, so that the threaded block 5 drives the connecting rod 7 to slide in the lifting groove 6.

[0034] Secondly, the connecting rod 7 drives the pressing block 11 to descend, so that the pressing block 11 contacts the lower end of the inner wall of the pressure pipe, and the bottom surface of the pressure pipe overlaps with the top surface of the positioning seat 1. Then the pressing block 11 pushes the buffer spring 12 to contract. At this time, the limiting block 10 slides in the limiting groove 8, and the limiting rod 9 slides in the limiting block 10, so as to achieve the effect of centering and positioning the pressure pipe.

[0035] Finally, by controlling the extension of the cylinder 18 on one side of the mounting bracket 19, the cylinder 18 pushes the upper positioning bracket 17, which in turn pushes the upper rotating rod 16 and the lower rotating rod 13 to rotate at the rotating shaft 14, and causes the torsion spring 15 to contract. This allows the pressure pipeline to be inspected and tested by controlling the detector 20.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
