[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a road and bridge inspection drilling and sampling device, including a support base 1, with limiting slide rods 103 symmetrically fixed on the support base 1, an upper bracket 104 fixed to the upper end of the limiting slide rods 103, an adjusting frame 2 between the upper bracket 104 and the support base 1, connecting lugs 201 fixed to both ends of the adjusting frame 2, the connecting lugs 201 being slidably connected to the limiting slide rods 103, a rotating connecting plate 401 rotatably mounted on the front of the adjusting frame 2, a bearing seat 4 fixed to the front of the rotating connecting plate 401, a drive shaft 403 rotatably mounted inside the bearing seat 4, a drive motor 402 fixed to the upper part of the bearing seat 4, the output end of the drive motor 402 being fixed to the drive shaft 403, a connector 404 fixed to the lower end of the drive shaft 403, a sampling bucket 6 fixed to the lower part of the connector 404, a dustproof sleeve 3 below the sampling bucket 6, and an avoidance hole 302 opened on the dustproof sleeve 3.

[0022] In this embodiment, starting the drive motor 402 can drive the drive shaft 403 to rotate. The rotation of the drive shaft 403 can drive the sampling barrel 6 to rotate via the connector 404. The connecting lug 201 and the limiting slide rod 103 are slidably engaged, and the adjusting frame 2 is slidably installed between the upper bracket 104 and the support seat 1. Adjusting the height of the adjusting frame 2 can drive the bearing seat 4 to move. The bearing seat 4 can drive the sampling barrel 6 to move. The high-speed rotating sampling barrel 6 moves down to drill holes in the bridge road for sampling. During the downward movement of the sampling barrel 6, it will pass through the avoidance hole 302, so that the dustproof sleeve 3 is fitted around the drilling position of the sampling barrel 6. Thus, the dust generated by the drilling will be blocked inside the dustproof sleeve 3, avoiding the problem of dust spreading in the air. The bearing seat 4 is rotatably installed on the front of the adjusting frame 2 via the rotating connecting plate 401, so that the bearing seat 4 can rotate at a certain angle. After sampling is completed, when the sample core is stuck inside the sampling barrel 6, the bearing seat 4 can be rotated to tilt the sampling barrel 6 at a certain angle, making it easier for the operator to remove the sample core inside the sampling barrel 6.

[0023] To achieve the purpose of driving the bearing seat 4 to move downward, the device adopts the following technical solution: support wheels 101 are fixedly connected to the bottom of the support seat 1 near the four corner edges, control box 102 is fixedly connected to the top of the support seat 1, threaded screw 105 is rotatably installed between the upper bracket 104 and the support seat 1, and a rotating handle 106 is fixedly connected to the upper end of the threaded screw 105. A threaded sleeve 203 is fixedly connected to the rear of the adjusting frame 2, and the threaded sleeve 203 is threadedly engaged with the threaded screw 105. A telescopic connecting rod 204 is fixedly connected to the bottom of the adjusting frame 2, and a compression spring 205 is sleeved on the telescopic connecting rod 204. A connecting foot 303 is fixedly connected to the rear of the dustproof sleeve 3, and the upper part of the connecting foot 303 is fixedly connected to the lower end of the telescopic connecting rod 204. A sealing gasket 301 is fixedly connected to the lower edge of the dustproof sleeve 3.

[0024] The device can be pushed on the ground by the support wheel 101, making it easy for operators to move the device. The support wheel 101 is equipped with a brake mechanism that can lock the roller. The control box 102 contains a battery to provide driving power for the drive motor 402. The rotating handle 106 can drive the threaded screw 105 to rotate. The threaded screw 105 is threadedly engaged with the threaded sleeve block 203. The rotation of the threaded screw 105 can drive the adjusting frame 2 to move up and down by the threaded sleeve block 203. The telescopic connecting rod 204 cooperates with the connecting foot 303 to install the dustproof sleeve 3 below the adjusting frame 2. At the same time, the compression spring 205 can provide a certain thrust to the connecting foot 303. The connecting foot 303 is pushed and will move the dustproof sleeve 3 downward. During the drilling and sampling process of the adjusting frame 2, the dustproof sleeve 3 will move down and fit against the road surface. The sealing gasket 301 can seal the gap between the dustproof sleeve 3 and the road surface.

[0025] To achieve the purpose of limiting the rotation of bearing housing 4, the device adopts the following technical solution: a limiter 5 is fixedly connected to one side of the rotating connecting plate 401, a limit groove 501 is opened in the limiter 5, a limit pin 502 is slidably installed in the limit groove 501, a limit hole 202 is opened on the front of the adjusting frame 2, the limit hole 202 and the limit pin 502 cooperate with each other, a spring washer 503 is fixedly connected to the limit pin 502, a return spring 504 is sleeved on the limit pin 502, and a pull ring 505 is fixedly connected to the end of the limit pin 502.

[0026] The return spring 504 can provide a certain thrust to the spring pad 503. When the spring pad 503 is pushed, it will drive the limit pin 502 to insert into the limit hole 202, thereby restricting the rotation of the rotating connecting plate 401 and keeping the bearing seat 4 and the sampling bucket 6 in a vertical position. The pull ring 505 can drive the limit pin 502 to move.

[0027] The working principle and usage process of this utility model are as follows: When using the device, it is necessary to move it to a suitable position so that the sampling barrel 6 is aligned with the position where drilling and sampling are required. Start the drive motor 402 to drive the sampling barrel 6 to rotate at high speed, and use the rotating handle 106 to drive the threaded screw 105 to rotate. The rotation of the threaded screw 105 can drive the adjusting frame 2 to move down. The downward movement of the adjusting frame 2 will simultaneously drive the dustproof sleeve 3 and the bearing seat 4 to move down. During the downward movement of the dustproof sleeve 3, after its bottom is in contact with the road surface, the telescopic connecting rod 204 and the compression spring 205 will be compressed, and the adjusting frame 2 will continue to drive the bearing seat 4 to move. The bearing seat 4 will drive the sampling barrel 6 to move down, so that the sampling barrel 6 passes through the avoidance hole 302 and contacts the road surface, thereby drilling and sampling the road surface to achieve the purpose of drilling and sampling.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
