[0016] Reference Figure 1-4 This utility model provides a weld inspection device for a steel oil storage tank, which includes a base 1. Two bases 1 are provided and are symmetrically distributed. A caster wheel 2 is fixedly connected to the lower side of the base 1. Two casters wheel 2 are provided on the lower side of the corresponding base 1. A hydraulic rod 3 is fixedly connected to the upper side of the two bases 1 respectively.

[0017] The output end of the right hydraulic rod 3 is fixedly connected to a semi-circular ring block 10, and the output end of the left hydraulic rod 3 is fixedly connected to a semi-circular ring block 21. The upper and lower sides of the semi-circular ring block 10 have track grooves 12, and the upper and lower sides of the semi-circular ring block 21 have track grooves 23. Rollers 16 are installed inside the track grooves 12, and rotating rods 17 are fixedly connected to the outer sides of the rollers 16. U-shaped blocks 18 are installed on the outer sides of the upper and lower rollers 16. Motors 19 are fixedly connected to the upper and lower sides of the U-shaped blocks 18, and a moving plate 20 is fixedly connected to the outer side of the U-shaped blocks 18. A weld inspection device 21 is fixedly connected to the outside of 20. A square groove 14 is opened on the right side of the semi-circular ring block 2 11. A square block 15 is fixedly connected to the left side of the semi-circular ring block 10. The semi-circular ring block 10 and the semi-circular ring block 2 11 are movably connected. There are two square grooves 14 and two square blocks 15. The square blocks 15 are set inside the corresponding square grooves 14 and are slidably connected to the semi-circular ring block 2 11. The upper end of the upper rotating rod 17 and the lower end of the lower rotating rod 17 pass through the U-shaped block 18 and are fixedly connected to the output end of the motor 19. The rotating rod 17 and the U-shaped block 18 are rotatably connected.

[0018] A fixing block 4 is fixedly connected to the upper side of the right base 1. The left end of the fixing block 4 is set on the upper side of the left base 1, and the front and rear sides of the left end of the fixing block 4 are slidably connected to the fixing block 5. The fixing block 5 is fixedly connected to the left base 1. A circular hole 6 is opened on the front side of the fixing block 4, and a circular hole 7 is opened on the front side of the fixing block 5. A threaded rod 8 is provided inside the circular hole 6 and the corresponding circular hole 7. A control block 9 is fixedly connected to the outer end of the threaded rod 8. The threaded rod 8 is threadedly connected to the fixing block 4 and the fixing block 5.

[0019] The operator uses a PLC controller and is electrically connected to the hydraulic rod 3, motor 19, and weld inspection equipment 21 to facilitate the operation of the control components. When the two bases 1 are put together, the operator holds the control block 9 and rotates the threaded rod 8 into the first circular hole 6 and the second circular hole 7 to fix the two connected bases 1, ensuring that the first semicircular ring block 10 and the second semicircular ring block 11 are connected together. This allows the roller 16 to rotate the weld inspection equipment 21 to detect circular welds. For straight welds, the hydraulic rod 3 can be directly activated to move the first semicircular slider and the second semicircular ring block 11 and related structures up and down, allowing the weld inspection equipment 21 to move up and down to detect straight welds. The setup of the first semicircular ring block 10, the second semicircular ring block 11, the roller 16, the rotating rod 17, the U-shaped block 18, the motor 19, the moving plate 20, and the weld inspection equipment 21 allows the operator to perform weld inspections on oil steel storage tanks without the aid of a scaffold, saving time and effort, making it convenient and quick, and reducing the workload of the operator.

[0020] Working principle: When using the device to inspect a vertical steel oil storage tank, the operator first pushes the base 1, which is followed by the casters 2, to the front of the tank. Then, the first fixing block 4 is slid into the corresponding second fixing block 5. Simultaneously, the square block 15 of the semi-circular ring block 2 is slid into the square groove 14 of the semi-circular ring block 10. At this point, the two hydraulic rods 3 are activated, moving the semi-circular ring block 10 and the second semi-circular ring block 11 to the desired inspection height. Then, the motor 19 is activated, causing the rotating rod 17 to rotate. The roller 16 rotates in track groove 12 and track groove 23. The rotation of the roller 16 causes the U-shaped block 18 to rotate around semi-circular ring block 10 and semi-circular ring block 21. At the same time, the U-shaped block 18 moves the moving plate 20. The moving plate 20 moves the weld detection device 21 to detect whether there is a leak at the weld joint of the oil steel storage tank. If a problem is detected, the buzzer alarm (not shown in the figure) will sound to remind the staff. At this time, the motor 19 stops rotating the roller 16, so that the weld detection device 21 stops at the weld leak.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
