Usually, pipeline valves need to be connected by welding, and welding inspection is usually required after welding. The existing detection and adjustment device fixes the X-ray flaw detector through a support frame structure. The X-ray flaw detector detects the weld of the pipeline valve after welding. The existing detection and adjustment device is difficult to rotate around the pipeline valve weld for inspection, and the staff needs to rotate the pipeline valve for inspection. The inspection is relatively cumbersome. At the same time, the pipeline valve weld is prone to missed inspection when the pipeline valve is rotated for inspection, resulting in inaccurate inspection.

At the same time, when the pipeline valve is rotated for detection, the pipeline valve weld is prone to missed detection, resulting in inaccurate detection.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pipeline valve welding detection device that is convenient for full-angle detection, including a lifting and adjusting structure, wherein a full-angle detection structure is provided inside the lifting and adjusting structure;

[0005] The lifting and adjusting structure comprises a base body with a counterweight at the bottom, and a mounting groove is provided on one side above the base body for convenient fixing and connecting the bearing seat, and a testing platform is fixed on the base body for convenient placement and testing of the pipeline valve;

[0006] The base body is rotatably connected to one end of the ball screw through a bearing seat, and the other end of the ball screw passes through a ball nut and is fixedly connected to the output end of the drive motor. At the same time, the other end of the drive motor is fixedly connected to the connecting frame through a fixing plate.

[0007] By adopting the above technical solution, the provided connecting frame can assist in stabilizing the connection.

[0008] Preferably, the other end of the connecting frame is fixedly connected to one end of the limiting slide rod, and the other end of the limiting slide rod passes through the slider and is fixedly connected to the base body, while both sides of the base body are fixedly connected to the controller and the display respectively through mounting brackets.

[0009] By adopting the above technical solution, the detection data can be displayed through the set display.

[0010] Preferably, the full-angle detection structure includes a connecting disk with a hollow structure inside, and through holes are opened on both sides of the connecting disk to facilitate the penetration and fixation of the hollow tube, and the inside of the connecting disk is fixedly connected to the outer ring of the mounting bearing.

[0011] By adopting the above technical solution, the inner and outer rings are fixed by the arranged mounting bearing.

[0012] Preferably, the inner ring of the mounting bearing is fixedly penetrated by a through pipe, and a hollow platform is fixed at one end of the through pipe, while a toothed disc is fixed at the other end of the through pipe, and an ultrasonic probe is fixed on the hollow platform.

[0013] By adopting the above technical solution, the two ends are welded and fixed by the provided through pipe.

[0014] Preferably, the toothed disc is meshed and adjusted with the bevel gear, and the bevel gear is fixedly connected to the output end of the output motor, and the output motor is fixedly connected to the bottom of the connecting disc through a fixing plate.

[0017] By adopting the above technical solution, the through pipe is provided to achieve through-installation.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the pipeline valve welding detection device which is convenient for full-angle detection,

[0019] (1) This case sets up a full-angle detection structure to solve the problem that the existing detection and adjustment device is difficult to rotate around the pipeline valve weld for detection. The staff needs to rotate the pipeline valve for detection, which is cumbersome. At the same time, the pipeline valve weld is prone to missed detection when the pipeline valve is rotated for detection, resulting in inaccurate detection. When the pipeline valve needs welding detection, the operator controls the output motor to drive the bevel gear to move. When the bevel gear is rotated under force, it drives the gear plate and the through pipe to rotate. When the through pipe is rotated under force, it drives the ultrasonic probe to rotate around the pipeline valve. The ultrasonic probe in the rotating movement can perform welding detection on the pipeline valve in all directions and at all angles;

[0020] (2) By setting up a lifting and lowering adjustment structure, the problem of the full-angle detection structure being unable to be lifted and lowered is solved, resulting in the full-angle detection structure being able to only perform surrounding detection at a fixed height. When the full-angle detection structure is in operation, the driving motor drives the ball screw to move, and during the movement of the ball screw, the ball nut and the slider drive the connecting plate to move synchronously. When the connecting plate moves up and down, the synchronous lifting interval distance of the ultrasonic probe is changed to facilitate comprehensive detection of the pipeline valve.
