Description

Technical Field

[0001] The utility model relates to the technical field of coring machines, in particular to a coring machine for highway engineering detection. Background Art

[0002] After the construction of a highway is completed, the quality of the highway needs to be tested to determine whether the highway meets the requirements and whether it can pass the acceptance inspection. When testing the highway, a coring machine is used to drill a piece of the completed highway and then send it to the test site for testing.

[0003] Because the diameter of the on-site core sampling sometimes cannot be selected to fully meet the standard aperture required for detection, it is necessary to conduct a second sampling of the sample in the coring barrel in the experimental site. In the prior art, the sampling barrel is fixed by the clamp of the sampling machine, and the sampling position is fixed. Sampling and testing are performed at different positions in the sample, and the clamp needs to be disassembled multiple times to change the position of the sampling barrel, resulting in low sampling efficiency. Therefore, there is an urgent need to design a coring machine for highway engineering inspection with high sampling efficiency. Utility Model Content

The spring rod is fixedly installed in the through hole, and one side of the clamping block is fixedly installed on the telescopic end of the spring rod.

[0009] As a further technical solution of the present utility model, a V-shaped limiting groove is provided on the other side of the clamping block.

A screw rod 15 is rotatably installed at the bottom of the movable base 1, one end of the screw rod 15 passes through the outer surface of the slider 16 and is threadedly connected thereto, a servo motor 17 is fixedly installed on one side of the bottom of the movable base 1, and a belt is sleeved between the output end of the servo motor 17 and the screw rod 15. Through the setting of the mobile structure of the equipment, the sampling bucket 13 can be carried through the bottom of the sampler body 3 for sampling. During the movement process, the gear 4 is meshed with the rack 5 to rotate, thereby driving the sampling bucket 13 to rotate. With the reciprocating movement of the mobile mechanism, the sampler body 3 can sample different positions of the sample in the sampling bucket 13, avoiding the need to disassemble the fixture to replace the position of the sampling bucket 13, thereby improving the sampling efficiency of the equipment.

[0023] Please see attached Figure 3 and attached Figure 4 In a preferred embodiment, the clamping mechanism includes a vertical plate 9, a clamping block 10 and a spring rod 12. The bottom end of the vertical plate 9 is fixedly installed on the top of the adapter plate 6. A through hole matching the spring rod 12 is provided on the surface of the vertical plate 9. The spring rod 12 is fixedly installed in the through hole. One side of the clamping block 10 is fixedly installed on the telescopic end of the spring rod 12. A V-shaped limiting groove is provided on the other side of the clamping block 10. The edges of the limiting groove are provided with rounded corners. One side of the clamping block 10 is linearly and evenly provided with multiple threaded holes 19. A handle 11 is rotatably installed on the other side of the clamping block 10.

Each handle 11 is connected to another clamping block 10 through the semi-threaded bolt 18. Threaded connection, by setting a clamping block 10, under the elastic force of the spring rod 12, the sampling barrel 13 can be clamped on the top of the shock absorber 7. The shock absorber 7 is preferably a rubber spring shock absorber, which adopts a spring made of rubber material and has good shock absorption and vibration isolation effects. When in use, the sampling barrel 13 with the sample is placed from above the two clamping blocks 10. According to the outer diameter of the sampling barrel 13, the two clamping blocks 10 are gradually pushed to compress the telescopic end of the spring rod 12. When the bottom of the sampling barrel 13 is against the top of the shock absorber 7, the handle 11 is turned, and the semi-threaded bolt 18 set at one end of the handle 11 is tightened in the threaded hole 19 of the other clamping block 10.

[0024] Please refer to the attached Figure 2 , in a preferred embodiment, a protective cover 2 is fixedly installed on the top of the mobile base 1. The protective cover 2 is in a U-shaped structure with an opening facing downwards. A sampling machine body 3 is installed on the top of the protective cover 2. A round hole for sampling is opened on the top of the protective cover 2. A transparent door 14 is hinged on one side of the protective cover 2 away from the clamping mechanism. A plurality of self-locking universal wheels are installed at the bottom of the mobile base 1. By setting the protective cover 2 and the transparent door 14, when the sampling machine body 3 samples the sample, it can prevent debris from splashing onto the operator. Through the transparent door 14, the operator can conveniently observe the sampling position and make adjustments, improving the practicability of the equipment.

[0025] Working principle: When in use, place the sampling bucket 13 on the top of the shock absorber 7. During the placement process, the two clamping blocks 10 can automatically adjust the spacing according to the diameter of the sampling bucket 13. The shock absorber 7 has a good shock absorption effect, preventing the sample from cracking due to resonance during sampling. Then, lock the two clamping blocks 10 through the two handles 11 to make the sampling bucket 13 stable on the top of the shock absorber 7. Start the servo motor 17 to drive the screw rod 15 to rotate. The screw rod 15 drives the slider 16 to slide along the chute 8, thereby driving the gear 4 to mesh with the rack 5 and rotate. The gear 4 drives the clamping mechanism to rotate, and then drives the sampling bucket 13 to rotate and move into the protective cover 2. Start the sampling machine body 3 to sample the sample from the top of the sampling bucket 13. As the sampling bucket 13 rotates and moves, multiple samplings at different positions can be realized, improving the sampling efficiency.
