[0041] Embodiment 2:

[0042] On the basis of Embodiment 1, please refer to Figure 2 、 Figure 3 and Figure 6 .

[0043] Specifically, limiting grooves 5 are provided at the bottoms of the first support frame 3 and the second support frame 4. At the bottoms of the inner walls of the two sliding frames 2, first hydraulic push rods 6 are connected respectively. The output ends of the two first hydraulic push rods 6 are respectively connected to the tops of the two limiting grooves 5. The clamping assembly 15 includes a support base 151. The support base 151 is connected to the output ends of the two second hydraulic push rods 14. A plurality of fixing plates 152 are connected to the top of the support base 151. Second springs 153 are connected to one sides of the plurality of fixing plates 152 respectively. A plurality of clamping plates 154 are respectively connected to the other ends of the second springs 153. The plurality of clamping plates 154 cooperate with each other. A placing seat 155 is connected to the top of the support base 151. The placing seat 155 is located below the support assembly 10. The distance between any point on the bottom of the plurality of clamping plates 154 and any point on the top of the placing seat 155 is greater than zero. A first rotating shaft 7 and a second rotating shaft 8 are respectively rotatably connected to the first support frame 3 and the second support frame 4. Two sides of the support plate 9 are respectively connected to the opposite ends of the first rotating shaft 7 and the second rotating shaft 8. A first gear 11 is connected to the second rotating shaft 8. The first gear 11 is located on the other side of the second support frame 4. A movable shaft 12 is rotatably connected to the other side of the second support frame 4. The movable shaft 12 is driven by an external motor, and the external motor used is not shown in the figure. A second gear 13 is connected to the movable shaft 12. The radius ratio of the first gear 11 to the second gear 13 is 1:5, so as to realize the first gear 11 smoothly meshing with and driving the second gear 13 to rotate. By adopting the above technical solution, the first support frame 3 and the second support frame 4 are pushed by the first hydraulic push rod 6, so that the first support frame 3 and the second support frame 4 are synchronously raised in the sliding frame 2, thereby driving the support plate 9 to be raised. After the cylinder block rotates, the height of the cylinder block is reduced, which is convenient for the staff to detect. The clamping plates 154 are pushed by the second springs 153. When the cylinder block is placed between the plurality of clamping plates 154, the cylinder block is clamped and limited. Since the distance between any point on the bottom of the clamping plates 154 and any point on the top of the placing seat 155 is greater than zero, it is avoided that the clamping plates 154 contact the placing seat 155, which affects the clamping operation. Through the radius ratio of the first gear 11 and the second gear 13, the driving operation of the first gear 11 on the second gear 13 is realized.

[0044] The working principle of the present utility model is as follows: During use, the staff places the cylinder block to be detected on the placement seat 155 at the top of the support seat 151, and places the cylinder block between multiple clamping plates 154. The top of the relative sides of the multiple clamping plates 154 is provided with slopes, which facilitates the smooth placement of the cylinder block on the placement seat 155. When placing, the surface of the cylinder block pushes the clamping plates 154, squeezing the second spring 153 between the clamping plates 154 and the fixed plate 152, causing the second spring 153 to undergo elastic deformation, so that the second spring 153 generates a thrust on the clamping plates 154. After the cylinder block is completely placed on the placement seat 155, the multiple second springs 153 on the fixed plate 152 synchronously push the clamping plates 154 to move closer to the middle, thereby pushing and clamping the placed cylinder block. After clamping, the staff can perform inspection operations on the inner wall of the cylinder block. After inspection, it is powered by an external power supply to drive the second hydraulic push rod 14 to start working. The two second hydraulic push rods 14 shorten synchronously, driving the support seat 151 to rise, thereby driving the cylinder block clamped on the support seat 151 to rise. During the rising process, the opening of the cylinder block contacts the support assembly 10 on the support plate 9. During the continuous rising of the cylinder block, the support assembly 10 gradually enters the cylinder block. When the clamping seat 1017 below the support block 1001 contacts the inner wall bottom of the cylinder block, the clamping seat 1017 squeezes the first spring 1016, causing the first spring 1016 to undergo elastic deformation, so that the first spring 1016 generates a thrust on the clamping seat 1017 to push the inner wall bottom of the tank body. Through the cooperation of the support seat 151, the clamping operation on the cylinder block is realized. After clamping, the second hydraulic push rod 14 stops working.

[0045] Through the operation of the motor 1012, the threaded rod 1013 is driven to rotate in the working groove 1011, driving the threaded barrel 1014 to descend on the threaded rod 1013, driving the sliding plate 1015 to descend in the working groove 1011, thereby driving the four sliding sleeves 1004 to descend synchronously on the four sliding rods 1003, driving the four first fixing seats 1005 to descend synchronously, driving the first push rod 1006 to rotate on the first fixing seat. Through the cooperation of the first push rod 1006, the other ends of the first push rod 1006 and the second push rod 1008 move away from the support block 1001, pushing the contact plate 1010 on the pin shaft 1009 to move around. After the contact plate 1010 touches the inner wall of the cylinder block, the motor 1012 stops working. Through the cooperation of the four contact plates 1010, the inner wall of the cylinder block is supported, assisting the support seat 151 and the clamping seat 1017 to clamp and limit the cylinder block, preventing the cylinder block from rotating on the support seat 151 when driving the cylinder block to move. Through the operation of an external motor, the movable shaft 12 is driven to rotate, driving the second gear 13 on the movable shaft 12 to rotate, meshing and driving the first gear 11 to rotate. Through the radius ratio of the first gear 11 and the second gear 13, the second gear 13 can rotate smoothly, driving the second rotating shaft 8 to rotate on the second support frame 4. With the assistance of the rotation of the first rotating shaft 7 on the first support frame 3, the support plate 9 is driven to rotate between the first support frame 3 and the second support frame 4, thereby driving the cylinder block fixed by the support assembly 10 and the clamping assembly 15 to rotate. After the second gear 13 rotates 180 degrees, the cylinder block is turned over and placed. The support assembly 10 supports the cylinder block. The movable shaft 12 stops rotating. Through the operation of the first hydraulic push rod 6, the two first hydraulic push rods 6 shorten synchronously, driving the first support frame 3 and the second support frame 4 to descend synchronously in the sliding frame 2, thereby driving the cylinder block to descend through the support plate 9, facilitating the staff to perform inspection operations on the cylinder block. The first hydraulic push rod 6 works, and the two second hydraulic push rods 14 extend synchronously, driving the clamping assembly 15 away from the cylinder block, thereby enabling the staff to perform inspection operations on the cylinder block in all directions.

[0046] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
