[0019] Please see Figs. 1-3 This utility model provides a technical solution: a highway pile hole diameter detector, including a circular plate 1, a first electric cylinder 11 fixedly installed at the bottom of the circular plate 1, a square connecting plate 12 fixedly installed at one end of the telescopic rod of the first electric cylinder 11, a first support rod 5 movably installed on the square connecting plate 12, an arc plate 6 movably installed at the end of the first support rod 5 away from the square connecting plate 12, a handle 10 fixedly installed at the top of the circular plate 1, and the first support rod 5 and the arc plate 6 are movably connected by a limiting block 14.

[0020] In practice, a spring 7 is fixedly installed between the center of the arc-shaped plate 6 near the top and the first support rod 5 near the bottom. Normally, under the action of the spring 7, the arc-shaped plate 6 is close to the first support rod 5. When the arc-shaped plate 6 moves closer to the inner wall of the pile hole, the bottom of the arc-shaped plate 6 will first contact the top and the inside of the pile hole, simultaneously pressing the arc-shaped plate 6 to rotate, increasing the contact area with the inner wall of the pile hole. The four first support rods 5 are movably installed on the four sides of the square connecting plate 12. Connecting blocks 3 are fixedly installed on the first support rods 5. A first protective cover 2 is fixedly installed on the bottom of the circular plate 1. A connecting block 3 that matches the connecting block 3 on the first support rod 5 is fixedly installed on the surface. A first connecting rod 4 is movably installed between the matching connecting blocks 3. A first guide groove 13 corresponding to the first support rod 5 is opened on the surface of the first protective cover 2. When the first electric cylinder 11 is activated, the telescopic rod drives the square connecting plate 12 and the first support rod 5 to compress downward. Under the action of the first connecting rod 4, the other end of the first support rod 5 tilts upward, and the arc plate 6 unfolds outward in a circular shape. This can quickly align the borehole detector 9 with the center of the pile hole, improving the detection speed and making it suitable for pile holes of different diameters.

[0021] See Figs. 1-3 A handle 10 is fixedly installed on the top of the circular plate 1, a first protective cover 2 is fixedly installed on the bottom of the circular plate 1, a motor 15 is fixedly installed on the first protective cover 2, a second electric cylinder 21 is rotatably installed at the center of the bottom of the motor 15, a circular connecting plate 22 is fixedly installed on one end of the telescopic rod of the second electric cylinder 21, a second connecting rod 18 is movably installed on the circular connecting plate 22, the end of the second connecting rod 18 away from the circular connecting plate 22 is movably installed on the second support rod 17, a brush 16 is fixedly installed on one end of the second support rod 17, and the other end is movably installed on the fixed plate 23.

[0022] In specific implementation, a connecting block 3 is fixedly installed near the center of the surface of the second support rod 17. The second support rod 17 is connected to the base plate 19 through the connecting block 3. There are two second connecting rods 18, which are movably installed on both sides of the circular connecting plate 22. The second support rod 17 is movably installed on both sides of the fixed plate 23 corresponding to the second connecting rod 18. A second protective cover 8 is rotatably installed at the bottom of the motor 15. The surface of the second protective cover 8 has a second guide groove 20 that matches the second support rod 17 and the second connecting rod 18. By starting the second electric cylinder 21, the telescopic rod... The circular connecting plate 22 and the second connecting rod 18 are compressed downwards. Under the action of the second connecting rod 18, the second support rod 17, together with the brush 16, unfolds outwards in a circular shape. When it unfolds to a suitable angle, the motor 15 is started. The second electric cylinder 21, the circular connecting plate 22, the second connecting rod 18 and the second support rod 17 drive the brush 16 to rotate back and forth, which can remove the residual soil on the inner wall of the pile hole, making it easier for the borehole detector 19 to accurately detect. The borehole detector 9 can rotate 360° without dead angles to detect, making the detection results more accurate.

[0023] Working principle: A first electric cylinder 11 is fixedly installed at the bottom of the circular plate 1. A square connecting plate 12 is fixedly installed at one end of the telescopic rod of the first electric cylinder 11. First support rods 5 are movably installed on all four sides of the square connecting plate 12. An arc-shaped plate 6 is movably installed at the end of the first support rod 5 away from the square connecting plate 12. The first support rod 5 and the arc-shaped plate 6 are movably connected by a limiting block 14. A spring 7 is fixedly installed between the center of the arc-shaped plate 6 near the top and the first support rod 5 near the bottom. Normally, under the action of the spring 7, the arc-shaped plate 6 is close to the first support rod 5. When the arc-shaped plate 6 moves closer to the inner wall of the pile hole, the bottom of the arc-shaped plate 6 will first contact the top and the inside of the pile hole, while simultaneously pressing the arc-shaped plate 6 to rotate, increasing the contact with the inside of the pile hole. The increased contact area of ​​the wall improves the stability of the aperture detector 9 during operation. The first support rod 5 is fixedly equipped with a connecting block 3, and the bottom of the circular plate 1 is fixedly equipped with a first protective cover 2. The surface of the first protective cover 2 is fixedly equipped with a connecting block 3 that matches the connecting block 3 on the first support rod 5. The first connecting rod 4 is movably installed between the matching connecting blocks 3. When the first electric cylinder 11 is activated, the telescopic rod drives the square connecting plate 12 and the first support rod 5 to compress downwards. Under the action of the first connecting rod 4, the other end of the first support rod 5 tilts upwards, causing the arc plate 6 to expand outwards in a circular shape. This allows the aperture detector 9 to quickly align with the center of the pile hole, improving the detection speed. At the same time, it is applicable to pile holes of different diameters, meeting the requirements of efficient construction.

[0024] By activating the second electric cylinder 21, the telescopic rod drives the circular connecting plate 22 and the second connecting rod 18 to compress downwards. Under the action of the second connecting rod 18, the second support rod 17, along with the brush 16, unfolds outwards in a circular shape. When it unfolds to a suitable angle, the motor 15 is activated. Through the second electric cylinder 21, the circular connecting plate 22, the second connecting rod 18, and the second support rod 17, the brush 16 is driven to rotate back and forth, which can remove the residual soil on the inner wall of the pile hole, facilitating the accurate detection of the borehole detector 19. The borehole detector 9 can rotate 360° without blind spots, making the detection results more accurate.
