Description

Technical Field

[0001] This utility model relates to the field of weld inspection technology, specifically to a pressure vessel cylinder weld inspection device. Background Technology

[0002] The reliability and safety of pressure vessels largely depend on their airtightness. During long-term use, pressure vessels are exposed to sunlight and rain, temperature changes, internal and external corrosion, and prolonged high or negative pressure, which can lead to leaks, and even ruptures or explosions. Because pressure vessels inherently possess a high degree of danger, if leaks are not addressed promptly, the pressure vessel itself may rupture or explode, or the leaked substance may be highly hazardous. Therefore, leak detection and flaw detection are essential for pressure vessels.

[0003] The specification of a pressure vessel weld inspection device (publication number CN211086195U) mentions that "one end of the flaw detector body is provided with a cable, the other end of the cable is provided with a probe, and it also includes a movable flaw detector bracket. The bottom of the movable flaw detector bracket is provided with casters. The movable flaw detector bracket includes an arc plate, a base plate, a side plate, and a panel. The arc plate contacts and cooperates with the side of the pressure vessel. There are two side plates, which are arranged perpendicular to the arc plate. The probe is embedded in a movable detection block. The movable detection block is set on the arc plate. A set of movable support components is provided at both ends of the movable detection block. The movable support components are set in the track grooves provided on the side plate. A reduction motor and a power supply are provided at the top of the arc plate. The movable support components are driven by the reduction motor and move in an arc along the arc plate together with the probe." However, the weld inspection device in the prior art cannot flexibly rotate the pressure vessel cylinder. It is not stable when the pressure vessel cylinder is being inspected, which affects the comprehensiveness and accuracy of its weld inspection. It is not accurate or stable. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a pressure vessel shell weld inspection device is provided to solve the problems of existing weld inspection devices not being able to flexibly rotate the pressure vessel shell, being unstable when inspecting the pressure vessel shell, affecting the comprehensiveness and accuracy of weld inspection, and being inaccurate and unstable.

[0005] To achieve the above objectives, a pressure vessel shell weld inspection device is provided, comprising a base, a transport platform, and a left clamping structure. Side fixing plates are fixed to both ends of the upper surface of the base, and a Z-axis linear guide rail is provided on the upper inner surface of the side fixing plates. A first slider is slidably connected to the Z-axis linear guide rail and fixed to the outer end of the transverse moving frame. A Y-axis linear guide rail is provided in the middle of the upper surface of the base, and the transport platform is slidably connected to the Y-axis linear guide rail.

A third X-axis linear guide rail is provided on the right side of the upper surface of the transport platform, and a right clamping structure is slidably connected to the third X-axis linear guide rail.

[0006] Furthermore, a first X-axis linear guide rail is provided in the middle of the transverse moving frame, and a second slider is slidably connected on the first X-axis linear guide rail.

The upper end of the telescopic cylinders is fixed under the support plate, and the support plate adopts an arc-shaped support plate structure.

[0009] Furthermore, the lower part of the transport platform is provided with a base plate, and the lower end face of the base plate is provided with a third slider on both the left and right sides. The third slider is slidably connected to the Y-axis linear guide rail.

[0010] Furthermore, a left mounting bracket is provided on the left side of the left clamping structure, and a fourth slider is provided at the lower end of the left mounting bracket. The fourth slider is slidably connected to the second X-axis linear guide rail. A first motor is installed in the middle of the right side of the left mounting bracket, and a first rotating shaft is installed at the front end of the first motor. The front end of the first rotating shaft is fixed to the center of the left clamping plate. Annular sleeve plates are provided on both the upper and lower parts of the right side surface of the left clamping plate. Anti-slip protrusions are provided on the inner side of the annular sleeve plates. The anti-slip protrusions are made of silicone rubber.

[0011] Furthermore, a right mounting bracket is provided on the right side of the right clamping structure, and a fifth slider is provided at the lower end of the right mounting bracket. The fifth slider is slidably connected to the third X-axis linear guide rail, and a connecting bushing is installed in the middle of the left side of the right mounting bracket.

By raising it to a certain height through the support plate, the left and right clamping structures on both sides can safely clamp the left and right ends of the pressure vessel cylinder on the telescopic cylinder.

[0015] 3. This utility model uses a fourth slider that slides on the second X-axis linear guide rail, and a fifth slider that moves flexibly on the third X-axis linear guide rail. This facilitates the clamping of pressure vessel cylinders of different lengths between the left and right clamping structures. Furthermore, the first motor rotates the first shaft to rotate the left clamping plate, while the right end of the second shaft is rotatably connected to the connecting bushing. This facilitates the movement of the pressure vessel cylinder clamped between the left and right clamping plates, allowing for comprehensive weld seam detection on its outer ring surface, resulting in more comprehensive and accurate detection.
