The lifting cylinder 501 is fixedly connected to the bottom plate 1, the mounting plate 502 is fixedly connected to the output shaft of the lifting cylinder 501, the semi-circular plate 503 is movably installed at the side position of the mounting plate 502, the radar flaw detector 504 is fixedly connected to the inner side position of the semi-circular plate 503, the lifting and adjusting assembly 5 further includes a roller 505, the roller 505 is movably installed at the inner side position of the semi-circular plate 503. Starting the lifting cylinder 501 makes the roller 505 roll on the surface of the circular pier 4, and the radar flaw detector 504 slides on the surface of the circular pier 4, so that the height of the radar flaw detector 504 is easy to adjust, thereby facilitating the movement of the radar flaw detector 504 to different height positions of the circular pier 4.

[0022] As Figures 1 to 4As shown in the figure, the side plate 506 is fixedly connected to the upper position of the semi-circular plate 503. The gear teeth 507 are fixedly connected to the side position of the side plate 506. The arc-shaped rod 509 is fixedly connected to the lower position of the semi-circular plate 503. The connecting platform 510 is fixedly connected to the mounting plate 502. The arc-shaped rod 509 is movably installed with the connecting platform 510. The side plate 506 is movably installed with the transmission gear 513 through the gear teeth 507. The lifting and adjusting assembly 5 further includes an arc-shaped sliding hole 511. The arc-shaped sliding hole 511 is opened on the connecting platform 510. The arc-shaped rod 509 is movably installed with the connecting platform 510 through the arc-shaped sliding hole 511. The lifting and adjusting assembly 5 further includes an arc-shaped limiting platform 508. The arc-shaped limiting platform 508 is fixedly connected to the upper surface position of the side plate 506 and is located inside the gear teeth 507. The lifting and adjusting assembly 5 further includes a stepping motor 512. The stepping motor 512 is fixedly connected to the mounting plate 502 and is located on the side of the connecting platform 510. The output shaft of the stepping motor 512 is fixedly connected to the transmission gear 513. The lifting and adjusting assembly 5 further includes a connecting rod 514 and a pressing plate 516. The connecting rod 514 is fixedly connected to the transmission gear 513. The pressing plate 516 is fixedly connected to the connecting rod 514. The pressing plate 516 is located above the arc-shaped limiting platform 508. The pressing plate 516 is slidably connected to the arc-shaped limiting platform 508. When the transmission gear 513 rotates, the gear teeth 507 mesh with the transmission gear 513 to drive, causing the side plate 506 to start moving left or right. The semi-circular plate 503 rotates and adjusts on the surface of the circular pier 4. The arc-shaped rod 509 moves in the arc-shaped sliding hole 511. The pressing plate 516 is slidably connected to the arc-shaped limiting platform 508, keeping the semi-circular plate 503 horizontal. By rotating the transmission gear 513, the radar flaw detector 504 is facilitated to adjust its position left or right, making the position adjustment of the radar flaw detector 504 more flexible and facilitating multi-point acquisition.

[0023] It should be noted that the present utility model is a bridge pier detection device with a lifting function. The shape of the semi-circular plate 503 is adapted to the shape of the circular pier 4. The bottom plate 1 is pushed by the push rod 3, and the bottom plate 1 moves on the ground through the universal wheels 2. The bottom plate 1 approaches the circular pier 4, so that the semi-circular plate 503 is stuck on the circular pier 4. The radar flaw detector 504 and the roller 505 are movably connected to the surface position of the circular pier 4. The lifting cylinder 501 is started, so that the mounting plate 502 moves upward, and all the structures above and on the side of the mounting plate 502 move upward synchronously. The height of the semi-circular plate 503 and the radar flaw detector 504 inside the semi-circular plate 503 is easy to adjust. When the semi-circular plate 503 moves to a suitable position, the stepping motor 512 is started, so that the transmission gear 513 rotates. The transmission gear 513 meshes with the teeth 507 of the side plate 506 for transmission. As the transmission gear 513 rotates, the side plate 506 rotates left or right. The arc-shaped rod 509 slides in the arc-shaped sliding hole 511 of the connecting platform 510. The arc-shaped limiting platform 508 rotates with the side plate 506. The pressing plate 516 rotates together with the transmission gear 513 and is slidably connected to the arc-shaped limiting platform 508 at the same time, restricting the arc-shaped limiting platform 508 in the lower position to prevent the semi-circular plate 503 from tilting forward, so that the semi-circular plate 503 remains in a horizontal state. The semi-circular plate 503 moves left or right, and the radar flaw detector 504 inside it moves synchronously, making the position adjustment of the radar flaw detector 504 more flexible, facilitating the staff to select more flaw detection collection points. Through multi-point flaw detection, the detection result of the circular pier 4 is more accurate.
