[0036] Combine Figures 1 to 5 As shown, an oil tank X-ray detection auxiliary mechanism includes an electric trolley 1, a suction cup mechanical arm 2, a height adjustment component 3 and an angle adjustment component 4.

[0037] The suction cup robotic arm 2 is arranged on the upper part of the electric trolley 1, and is used to absorb the X-ray film and stick the X-ray film on the inner wall of the oil tank cavity; the height adjustment component 3 is rotatably arranged on the upper part of the electric trolley 1, and the suction cup robotic arm 2 is fixedly provided on the top of the height adjustment component 3, and the height adjustment component 3 is used to adjust the height of the suction cup robotic arm 2; the angle adjustment component 4: the mounting end of the angle adjustment component 4 is hinged to the electric trolley 1, and the output end of the angle adjustment component 4 is hinged to the height adjustment component 3, and the angle adjustment component 4 is used to adjust the angle of the suction cup robotic arm 2.

[0038] Among them, through the combined action of the electric trolley 1 and the suction cup robotic arm 2, the suction cup robotic arm 2 can quickly and accurately absorb and stick the X-ray film on the inner wall of the oil tank cavity. At the same time, the electric trolley 1 serves as a mobile platform to drive the suction cup robotic arm 2 to move freely in the oil tank, so that the X-ray film can be stuck at any position in the oil tank cavity, greatly reducing the labor intensity of the staff; through the combined action of the height adjustment component 3 and the angle adjustment component 4, the angle and height of the suction cup robotic arm 2 can be adjusted according to actual conditions, so that the X-ray film can be stuck at any position in the oil tank cavity to meet the needs of oil tank weld detection. At the same time, there is no need to build a full-floor scaffolding, reducing the safety risks of the staff. Only in this way can the X-ray film be easily stuck on the vertical, inclined or curved inner wall, greatly improving the convenience and accuracy of detection, and also reducing the labor intensity and safety risks of the staff.

[0039] It should be noted that the electric car 1, the suction cup robot arm 2, the height adjustment component 3 and the angle adjustment component 4 are all wirelessly connected and controlled with an external control terminal by adopting a wireless connection method.

[0040] Combine Figure 2 、 Figure 3 and Figure 4 As shown, the height adjustment assembly 3 includes: a mounting base 31, a lifting block 33, a drive motor 34, and an adjustment screw 35. The mounting base 31 is rotatably mounted on the upper portion of the electric trolley 1, and a mounting slot 32 is defined on the mounting base 31; the lifting block 33 is slidably sleeved within the mounting slot 32; the drive motor 34 is disposed below the mounting base 31, and the output end of the drive motor 34 passes through the mounting base 31 and extends into the mounting slot 32; the adjustment screw 35 is vertically rotatably mounted within the mounting slot 32, with the bottom end of the adjustment screw 35 rotatably connected to the output end of the drive motor 34, and the top end of the adjustment screw 35 extends into the interior of the lifting block 33.

[0041] Among them, when the height of the suction cup robot arm needs to be adjusted, a wireless command is sent to the drive motor 34 through the control end, and the drive motor 34 starts after receiving the command, and drives the adjusting screw 35 to rotate through the output end of the drive motor 34. During the rotation of the adjusting screw 35, since the lifting block 33 and the mounting groove 32 are in sliding fit, and the lifting block 33 is provided with a thread matching the adjusting screw 35, the lifting block 33 will move along the adjusting screw 35 and under the restriction of the mounting groove 32 of the mounting seat 31, the lifting block 33 can only produce corresponding up and down movements. The up and down movement of the lifting block 33 will drive the suction cup robot arm to rise or fall synchronously, thereby realizing height adjustment.

[0042] Combine Figure 3 and Figure 4 As shown, a limit ring 311 is fixed to the upper portion of the mounting base 31, and a limit plate 331 is fixed to the lower portion of the lifting block 33 to prevent the lifting block 33 from sliding out of the mounting slot 32. When the adjusting screw 35 rotates, the lifting block 33 moves up and down along the adjusting screw 35. Without a limiter, after the lifting block 33 moves upward to a certain height, it may completely disengage from the mounting slot 32, causing the suction cup robot arm to lose support and fall, causing damage to the equipment or personal injury. The provision of the limit ring 311 and limit plate 331 effectively prevents this from happening. When the lifting block 33 rises to a certain height, the limit plate 331 contacts the limit ring 311, preventing the lifting block 33 from rising further. Similarly, when the lifting block 33 descends to a certain height, it is restrained by the limit plate 331 and limit ring 311, preventing it from descending further.

[0043] Combine Figure 1 As shown, the mounting seat 31 is rotatably mounted on the electric vehicle 1 through the first mounting plate 11 , and mounting posts 312 are fixedly mounted on both sides of the mounting seat 31 , and the mounting posts 312 are rotatably sleeved on the first mounting plate 11 .

[0044] By providing mounting posts 312 on either side of the mounting base 31 and rotatably fitting the mounting posts 312 onto the first mounting plate 11, the mounting base 31 and its height adjustment assembly can rotate within a certain range relative to the electric trolley. This allows the angle adjustment assembly to easily adjust the suction cup arm's angle to accommodate X-ray film placement requirements at various locations and angles.

[0045] Combine Figure 1 and Figure 5 As shown, a second mounting plate 12 is fixedly mounted on either side of the upper portion of the electric trolley 1. The second mounting plate 12 is located on one side of the first mounting plate 11. An angle adjustment assembly 4 is hingedly connected between the two second mounting plates 12. The angle adjustment assembly 4 includes a telescopic cylinder 41 and a sleeve 42. The telescopic cylinder 41 is rotatably mounted between the two second mounting plates 12. The sleeve 42 is fixedly mounted on the output end of the telescopic cylinder 41, and one end of the sleeve 42 is hingedly connected to the mounting base 31.

[0046] Among them, when it is necessary to adjust the angle of the suction cup robot arm, a wireless command is sent to the telescopic cylinder 41 through the control end. The telescopic cylinder 41 starts after receiving the command, and the sleeve 42 is driven to move through the output end of the telescopic cylinder 41. The movement of the sleeve 42 will cause the mounting base 31 and the height adjustment component thereon to rotate around the hinge point of the two first mounting plates 11, thereby changing the angle of the suction cup robot arm.

[0047] The working mode of the utility model is as follows:

[0048] First, a wireless command is sent to the suction cup robot arm 2 through the control end, causing the suction cup on it to absorb the X-ray film. Then, the electric trolley 1 moves inside the oil tank, moving the suction cup robot arm 2 and the X-ray film to the predetermined position. When the height of the suction cup robot arm 2 needs to be adjusted, a wireless command is sent to the drive motor 34 of the height adjustment component 3 through the control end. After receiving the command, the drive motor 34 starts and drives the adjustment screw 35 to rotate. Because the lifting block 33 is provided with a thread that matches the adjustment screw 35, and the lifting block 33 and the mounting slot 32 are slidably matched, the lifting block 33 will move up and down along the adjustment screw 35. The movement of the lifting block 33 will drive the suction cup robot arm 2 to rise or fall synchronously, thereby achieving height adjustment. When the angle of the suction cup robot arm 2 needs to be adjusted, a wireless command is sent to the telescopic cylinder 41 of the angle adjustment component 4 through the control end. After receiving the command, the telescopic cylinder 41 starts and drives the sleeve 42 to move through its output end. The movement of the sleeve 42 causes the mounting base 31 and the height adjustment assembly thereon to rotate around the hinge points of the two first mounting plates 11, thereby changing the angle of the suction cup robot arm 2. This allows the suction cup robot arm 2 to attach the corresponding X-ray film to the inner wall of the corresponding oil tank.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention.
