[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, a lifting mechanism is provided inside. The clockwise rotation of the motor drives the first helical gear to rotate, which in turn drives the second helical gear to rotate, causing the threaded screw to rotate. This causes the screw seat on the threaded screw to move, and simultaneously the first pressing block on the screw seat moves, causing the first pressing block to press the first pressing rod. This causes the first pressing rod to move inward, which in turn presses the second pressing rod. Consequently, the second pressing rod moves inward, pressing the second pressing block. This causes the second pressing block to move upward, causing the lifting block on the second pressing block to move upward, and finally, the lifting block moves upward and out of the through slot at the top of the first cavity. Through this design, the manhole cover on the fixed seat is lifted by the lifting block, creating a gap between the manhole cover and the fixed seat. This provides a gripping space for the manhole cover, making it easier for workers to remove the manhole cover from the fixed seat, thereby speeding up the testing process.

[0014] 2. In this utility model, a clamping mechanism is provided inside. The motor rotates counterclockwise, driving the first helical gear to rotate, which in turn drives the second helical gear on the first helical gear to rotate. This causes the threaded screw on the second helical gear to rotate, which in turn causes the screw seat on the threaded screw to move inward. This causes the connecting frame on the screw seat to move, which in turn causes the connecting rod on the connecting frame to move. At the same time, the second bonding plate on the connecting rod moves, so that the first bonding plates on both sides of the second bonding plate come into contact with the manhole cover. This causes the first bonding plate to rotate after being squeezed. Through this design, the first bonding plate can better fit manhole covers of different sizes, which can better ensure the clamping mechanism's fixation of the manhole cover, thereby ensuring the stability of the manhole cover on the fixed base.

The second extrusion rod 604 is attached to one side of the second extrusion block 603. A groove is provided on one side of the inner cavity of the first cavity 7. The bottom of the second extrusion rod 604 is slidably connected to the inner cavity of the groove in the first cavity 7 by a slider.

[0023] Specifically: When the manhole cover needs to be removed, the motor 404 rotates clockwise, driving the first helical gear 401 to rotate, which in turn causes the second helical gear 402 on the first helical gear 401 to rotate. This causes the threaded screw 403 on the second helical gear 402 to rotate, which in turn causes the screw seat 405 on the threaded screw 403 to move. Simultaneously, the first pressing block 601 on the screw seat 405 moves, causing the first pressing block 601 to press the first pressing rod 602. This causes the first pressing rod 602 to move inward, thereby pressing the second pressing rod 602. Rod 604, so the second extrusion rod 604 moves inward, causing the second extrusion rod 604 to press the second extrusion block 603, causing the second extrusion block 603 to move upward, causing the lifting block 608 on the second extrusion block 603 to move upward and thus move out of the through slot opened at the top of the first cavity 7, thereby causing the manhole cover on the fixed seat 3 to be lifted, thus creating a gap between the manhole cover and the fixed seat 3, thus creating a gripping space for the manhole cover, making it easier for the staff to remove the manhole cover from the fixed seat 3, thereby speeding up the testing progress.

[0024] The clamping mechanism 5 further includes: A connecting frame 501 is connected at its bottom to the top of a lead screw seat 405. A connecting rod 507 is connected to one side of the connecting frame 501. One end of the connecting rod 507 is connected to one side of a second bonding plate 503. A first bonding plate 502 is rotatably connected to both sides of the second bonding plate 503. A first rotating rod 504, one end of which is rotatably connected to one side of the first bonding plate 502 at the corresponding position, and the other end of which is rotatably connected to a second rotating rod 506. One side of the first extrusion block 601 is connected to one side of the corresponding screw seat 405. Both ends of the bottom of the lifting block 608 are connected to the second spring 605. The other end of the second spring 605 is connected to one side of the inner cavity of the first cavity 7. The connecting rod 507 has movable cavities on both sides. The outer side of the second rotating rod 506 is slidably connected to the inner side of the movable cavity of the corresponding connecting rod 507. One side of the second rotating rod 506 is connected to the first spring 505. The other end of the first spring 505 is connected to one side of the movable cavity of the corresponding connecting rod 507. The outer side of the screw seat 405 is attached to the inner side of the inner cavity of the third cavity 9. The top of the fixed seat 3 is connected to the support frame 1. One side of the support frame 1 is connected to the hydraulic cylinder 2.

[0025] Specifically: When clamping the manhole cover, the motor 404 first rotates counterclockwise, driving the first helical gear 401 to rotate, which in turn drives the second helical gear 402 on the first helical gear 401 to rotate. This causes the threaded screw 403 on the second helical gear 402 to rotate, which in turn causes the screw seat 405 on the threaded screw 403 to move inward. This causes the connecting frame 501 on the screw seat 405 to move, which in turn causes the connecting rod 507 on the connecting frame 501 to move. At the same time, the second bonding plate 503 on the connecting rod 507 moves, so that the first bonding plates 502 on both sides of the second bonding plate 503 come into contact with the manhole cover. This causes the first bonding plates 502 to rotate after being compressed, which allows the first bonding plates 502 to better fit manhole covers of different sizes and better ensures the stability of the manhole cover on the fixing seat 3.

[0026] Working principle: When clamping the manhole cover, the motor 404 rotates counterclockwise, driving the first helical gear 401 to rotate, which in turn rotates the second helical gear 402 on the first helical gear 401. This causes the threaded screw 403 on the second helical gear 402 to rotate, which in turn causes the screw seat 405 on the screw 403 to move inward. This causes the connecting frame 501 on the screw seat 405 to move, which in turn causes the connecting rod 507 on the connecting frame 501 to move. Simultaneously, the second helical gear 407 on the connecting rod 507... The bonding plate 503 moves, causing the first bonding plates 502 on both sides of the second bonding plate 503 to contact the manhole cover. This causes the first bonding plates 502 to rotate under pressure, simultaneously moving the first rotating rod 504 on the first bonding plate 502. This causes the second rotating rod 506 on the first rotating rod 504 to move within the moving cavity, resulting in the second rotating rod 506 compressing the first spring 505. When the manhole cover needs to be removed, the motor 404 first rotates clockwise... The rotation of the needle drives the first helical gear 401 to rotate, causing the second helical gear 402 on the first helical gear 401 to rotate, which in turn causes the threaded screw 403 on the second helical gear 402 to rotate. This causes the screw seat 405 on the threaded screw 403 to move outward, causing the first spring 505 to be compressed and the first bonding plate 502 to return to its original position. At the same time, the first pressing block 601 on the screw seat 405 moves, causing the first pressing block 601 to press the first pressing rod 602, which in turn causes the first pressing rod 602 to move inward, thus pressing the second pressing rod 604. As a result, the second pressing rod 604 moves inward, pressing the second pressing block 603, which in turn causes the second pressing block 603 to move upward. This causes the lifting block 608 on the second pressing block 603 to move upward, thus moving the lifting block 608 upward into the through slot opened at the top of the first cavity 7. This causes the manhole cover on the fixed seat 3 to be lifted, thus creating a gap between the manhole cover and the fixed seat 3.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
