[0052] Punching member 402: Two punching members 402 are provided. Both punching members 402 are provided below the support frame 2. The upper surface of the right punching member 402 is fixedly connected to the lower end surface of the right output shaft 304. The upper surface of the left punching member 402 is rotatably connected to the outer surface of the left output shaft 304 via a bearing.

[0053] Sliding plate 403: The outer surface of the sliding plate 403 is fixedly connected to the inner wall of the left punching member 402, the inner wall of the sliding plate 403 is slidingly connected to the upper end surface of the first stroke column 302, and the inner wall of the sliding plate 403 is rotationally connected to the outer surface of the left output shaft 304 through a bearing.

[0054] The above scheme is adopted: the right output shaft 304 is driven to rotate by the motor 401, and the right output shaft 304 drives the right punching piece 402 to rotate to punch holes in the ground. After punching, the output shaft 304 on the left punching piece 402 is docked with the output end of the motor 401, and the motor 401 is started again. The motor 401 drives the left output shaft 304 to rotate, and the left output shaft 304 drives the travel disk 303 to rotate, so that the inner wall of the travel disk 303 squeezes the outer surface of the first travel column 302, and the first travel column 302 slides inward along the inner wall of the sliding disk 403.

[0071] The above solution is adopted: in order to rotate the travel bar 603, by starting the electric cylinder 804, the electric cylinder 804 pushes or pulls back the rack 803, so that the rack 803 and the outer surface of the gear 802 engage with each other, and the gear 802 rotates with the support column 801 as the rotation center. At the same time, the gear 802 can drive the support column 801 to rotate together, and the support column 801 drives the travel bar 603 to rotate together.

[0076] The working principle of this utility model:

[0077] When in use, by starting the motor 401, the motor 401 drives the right output shaft 304 to rotate, and the right output shaft 304 drives the right punching piece 402 to rotate to punch holes in the ground. After punching, the electric cylinder 804 is started, and the electric cylinder 804 pushes the rack 803, so that the rack 803 and the outer surface of the gear 802 are meshed with each other, and the gear 802 rotates with the support column 801 as the rotation center. At the same time, the gear 802 can drive the support column 801 to rotate, and the support column 801 drives the stroke bar 603 to rotate together. The inner wall of the stroke bar 603 squeezes the outer surface of the second stroke column 602, so that the second stroke column 602 slides along the inner wall of the stroke bar 603, and the second stroke column 602 on the left can drive the fixing piece 601 below to move toward the motor 401 output end approaches, and the other fixing part 601 is driven by the second stroke column 602 on the right side to start moving away from the output end of the motor 401. The left fixing part 601 pushes the left output shaft 304 close to the main shaft of the motor 401 until the left positioning column 502 enters the positioning groove 501 and completes the docking with the output end of the motor 401. The motor 401 is started again, and the motor 401 drives the left output shaft 304 to rotate. The left output shaft 304 drives the stroke disk 303 to rotate, so that the inner wall of the stroke disk 303 squeezes the outer surface of the first stroke column 302, and the first stroke column 302 slides inward along the inner wall of the sliding disk 403. At the same time, the first stroke column 302 can drive the grab plate 301 to move inward together until the gravel inside the hole is clamped and taken out.

[0078] To sum up: this drilling device for road and bridge inspection, through the base 1, support frame 2, grabbing assembly 3, driving assembly 4, positioning assembly 5, stroke assembly 6, sliding groove 7, transmission assembly 8 and telescopic assembly 9, solves the problem of unstable road foundation caused by gravel remaining in the hole, because these gravel will become new stress concentration points, which may cause further crack expansion and reduce the overall bearing capacity and stability of the road.
