[0029] When implementing

[0030] When in use, first install the transmission mechanism and the lifting mechanism on the outside of the normal pressure container 1, keep the hydraulic cylinder 14 in a fully retracted state, and then start the ultrasonic probe 33. The ultrasonic probe 33 reflects the situation of the normal pressure container 1 here to the ultrasonic inspection device. The ultrasonic inspection device converts the signal fed back by the ultrasonic probe 33 into an image. The staff can judge whether the outer wall of the normal pressure container 1 is damaged by observing the ultrasonic inspection device, and then start the second drive motor 30. The output shaft of the second drive motor 30 drives the connecting shaft 29 and the gear 28 to rotate, and the gear 28 drives the gear ring 27 and the second matching block 26 to rotate, so that the limit block slides in the limit groove. , the second matching block 26 drives the fixing sleeve 32 and the ultrasonic probe 33 to rotate around the normal pressure container 1. When the ultrasonic probe 33 moves to a suitable position, the normal pressure container 1 continues to be inspected, and this process is repeated until the normal pressure container 1 is inspected all around. Then, the lifting mechanism is started at the same time, and the lifting mechanism drives the first matching block 25 to rise, and the normal pressure container 1 continues to be inspected all around until the inspection of the entire surface of the normal pressure container 1 is completed. The staff does not need to hold the infrared inspection device to inspect the normal pressure container 1. The staff only needs to stay in place to complete the inspection of the normal pressure container 1, thereby avoiding the situation where the staff is physically exhausted and the inspection efficiency is reduced.

[0031] When the lifting mechanism raises the first matching block 25, it first ensures that the clamping assembly fixes the second support block 18, starts the hydraulic cylinder 14, and the telescopic end of the hydraulic cylinder 14 drives the fixed block 13 and the third movable block 15 to move upward. The third movable block 15 drives the second support block 18 and the first matching block 25 to move upward through the clamping assembly. When the hydraulic cylinder 14 is fully extended, the staff moves the first support block 17 into the transmission mechanism through the through slot 9, so that the first support block 17 is clamped in the corresponding second fixed slot 8 on the first movable block 3 and the second movable block 4. At this time, the first support block 17 is vertically aligned with one group of the second support blocks 18, and then the fixation between the first movable block 3 and the base 2 is released by controlling the fixing mechanism. Then the staff rotates the first movable block 3, and the first movable block 3 drives the first support block 17 and the second movable block 4 to rotate, and several groups of slides move in the corresponding slide rails 5. At this time The first movable block 3, the second movable block 4 and the first supporting block 17 remain relatively still. When the adjacent second fixed groove 8 is aligned with the through groove 9, the staff continues to clamp the first supporting block 17 into the corresponding second fixed groove 8, and repeats this process until all the second fixed grooves 8 on the first movable block 3 and the second movable block 4 are clamped with the first supporting block 17. Then the staff controls the hydraulic cylinder 14 to descend, clamps one end of the second supporting block 18 into the corresponding first supporting block 17, and then controls the clamping assembly to release the fixation between the third movable block 15 and the second supporting block 18. Then the staff continues to control the hydraulic cylinder 14 to descend until the hydraulic cylinder 14 is completely retracted. At this time, the clamping assembly is aligned with the clamping groove 19 on the first supporting block 17. Then the clamping assembly is controlled to fix the first supporting block 17. Then the hydraulic cylinder 14 is controlled to rise, and the hydraulic cylinder 14 drives the third movable block 15 and the first matching block 25 to rise.

[0032] When the hydraulic cylinder 14 is fully extended, the staff places the second support block 18 in the first fixed groove 7, and then releases the fixation between the second movable block 4 and the first by controlling the fixing mechanism. Then the staff rotates the second movable block 4 to drive several groups of sliders 6 to move in the slide rail 5, and the second movable block 4 drives the second support block 18 to rotate. At this time, the base 2 and the first movable block 3 are fixed, and the second support block 18 is stationary relative to the second movable block 4 until the second support block 18 is clamped in the first fixed groove 7. Then the hydraulic cylinder 14 is controlled to clamp one end of the second support block 18 in the corresponding first support block 17, and then the clamping assembly is controlled to release the fixation between the first support block 17 and the third movable block 15. The third movable block 15 is moved to the position where the clamping assembly can fix the second support block 18 by the third hydraulic cylinder 14, and this is repeated; the position of the ultrasonic probe 33 is moved upward, and the staff can place the first support block 17 / second support block 18 in the transmission mechanism while the ultrasonic probe 33 is inspecting the atmospheric pressure container 1, which can save time and thus improve the efficiency of inspection.

[0033] When the support mechanism needs to be disassembled, the staff first drives the support mechanism and the first matching block 25 to descend through the lifting mechanism until the first support block 17 / the second support block 18 is moved to the corresponding first fixing groove 7 / the second fixing groove 8, and then controls the clamping assembly to separate from the first support block 17 / the second support block 18, and then controls the lifting mechanism to rise until the clamping assembly is aligned with the adjacent first support block 17 / the second support block 18, fixes the adjacent first support block 17 / the second support block 18 through the clamping assembly, and then the staff separates the first support block 17 from the adjacent second support block 18, and takes out the first support block 17 / the second support block 18, and repeats this process to complete the disassembly of the support mechanism; when inspecting the atmospheric pressure container 1, the atmospheric pressure container 1 is inspected at intervals at the inspection height, and half of the inspection points of the atmospheric pressure container 1 are inspected when ascending, and the other half of the inspection points of the atmospheric pressure container 1 are inspected when descending, which can reasonably use time. While inspecting the atmospheric pressure container 1, the staff can start to disassemble and assemble the support mechanism, thereby reasonably using time and improving the efficiency of inspection.

[0034] When it is necessary to release the fixing of the fixing mechanism, move the bayonet 10, and the bayonet 10 slides in the connecting sleeve 11 until one end of the bayonet 10 is aligned with the positioning groove 12, and then rotate the bayonet 10 so that one end of the bayonet 10 is clamped in the corresponding positioning groove 12; when the bayonet 10 is clamped in the fixing groove farther away from the base 2, the other end of the bayonet 10 is separated from the first movable block 3 and the second movable block 4, and the first movable block 3 can rotate on the base 2; when the bayonet 10 is clamped in the fixing groove closer to the base 2, the other end of the bayonet 10 is separated from the second movable block 4, and the second movable block 4 can move on the first movable block 3; when fixing is required, it is necessary to ensure that the bayonet 10 is aligned with one of the groups of pin holes 34 on the first movable block 3 / second movable block 4, and then the staff rotates the bayonet 10 to separate it from the positioning groove 12, and then moves the bayonet 10, and installs the bayonet 10 in the pin hole 34 to fix the base 2, the first movable block 3 and the second movable block 4.

[0035] When using the clamping assembly to fix the first support block 17 / the second support block 18, it is first necessary to ensure that the block 22 is aligned with the corresponding slot 19, and then start the first drive motor 20. The output shaft of the first drive motor 20 drives the double-headed screw 21 to rotate through the coupling, and the double-headed screw 21 drives the two groups of blocks 22 to move in the sliding groove 24, and the two groups of blocks 22 move in opposite directions until the block 22 is clamped in the corresponding slot 19, and the first support block 17 / the second support block 18 is fixed; when it is necessary to release the fixation of the first support block 17 / the second support block 18, start the first drive motor 20. At this time, the first drive motor 20 rotates in the opposite direction, driving the two groups of blocks 22 to move, so that the blocks 22 are separated from the corresponding slots 19.

[0036] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the utility model.
