Description

Technical Field

[0001] The invention relates to the technical field of ground material sampling and detection, in particular to roadbed compaction detection equipment. Background Art

[0002] Roadbed is generally formed by the compaction of soil from the ground material. Roadbed compaction generally refers to the ratio of the dry density of the ground material after compaction to the standard maximum dry density. Roadbed compaction is a key indicator for evaluating the quality of roadbed and pavement construction, characterizing the density after on-site compaction. Higher compaction, greater density, and better overall material performance are generally achieved through coring and sampling of the ground material and measurement of relevant parameters to determine the compaction value.

[0003] Existing detection devices are generally sampling core drilling machines used as auxiliary extraction. As the ground material is extracted, it is generally pressed into a standard mold by hand, and then weighed and calculated. During this period, manual filling and pressing operations are required. Since the pressing force is controlled by manpower, there is still a difference in the compaction degree between the actual pressed soil sample and the actual ground material. This is generally due to the sampling error caused by manual operation, which also makes the actual calculated compaction degree have reference value but is not accurate. Summary of the Invention

[0040] When in use, the segmented storage part 11 is docked with the hole frame 7, and the segmented storage part 11 is inserted into the outer cylinder 8, and then the rotating connection part 6 connects the hole frame 7 and the segmented storage part 11. Under the drive of the rotating connection part 6, the hole frame 7 and the segmented storage part 11 rotate synchronously, and under the transmission of the outer cylinder 8, the barrel drill bit 10 rotates with the outer cylinder 8, the multi-stage active telescopic frame 5 contracts, and the rotating connection part 6 drops, so that the rotating connection part 6 drives the hole frame 7 to move downward, so that the outer cylinder 8 and the barrel drill bit 10 drill into the soil layer. At this time, the drilled soil core enters the segmented storage In the storage portion 11, as the multi-stage active telescopic frame 5 extends, the outer cylinder 8 and the cylindrical drill bit 10 are both separated from the soil, and then the clamping ring structure 12 is used to clamp the ring body 9 to limit the outer cylinder 8 and the cylindrical drill bit 10, and the rotating connection part 6 is separated from the hole frame 7, and the rotating connection part 6 docks the segmented storage portion 11. As the multi-stage active telescopic frame 5 further extends, the rotating connection part 6 removes the segmented storage portion 11 from the outer cylinder 8, and then the cutting and sampling structure 13 cuts the segmented storage portion 11 into several samples of equal volume and stores and collects them for subsequent direct weighing.

There are two adjacent groups of sample tubes 14, between the group of sample tubes 14 arranged at the bottom and the plug-in ring 15, and between the group of sample tubes arranged at the top. A cutting layer 47 is provided between the tube 14 and the connecting tube 16. The material of the cutting layer 47 can be selected from hot melt adhesive or solidified glue. The connecting tube 16 is fixedly connected to a plug-in block 17 movably connected to the rotating connecting part 6. A first docking hole 18 is provided on the plug-in block 17. A second docking hole 19 is provided on the plug-in block 17. The second docking hole 19 is movably connected to the rotating connecting part 6. The plug-in block 17 is movably connected to the hole frame 7. The hole frame 7 is provided with a through hole structure with the same aperture as the second docking hole 19. When installing the segmented storage part 11 into the outer cylinder 8, it is necessary to dock the plug-in ring 15 with the barrel drill bit 10, and insert the plug-in block 17 into the hole rack 7, so that the through hole of the hole rack 7 is docked with the second docking hole 19. As the rotating connecting part 6 passes through the hole rack 7 and docks with the second docking hole 19, the outer cylinder 8, the ring body 9, the barrel drill bit 10, and the segmented storage part 11 rotate synchronously. As the rotating connecting part 6 disengages from the second docking hole 19 and the hole rack 7 and docks with the first docking hole 18, as the ring body 9 is clamped by the ring structure 12, the rotating connecting part 6 applies an upward force to the first docking hole 18 to remove the plug-in ring 15, the connecting cylinder 16, the sample cylinder 14, the cutting layer 47, and the plug-in block 17 from the outer cylinder 8 together.

[0042] In one case of this embodiment, the rotating connection part 6 includes a power shell 20 fixedly connected to the multi-stage active telescopic frame 5, the power shell 20 is fixedly connected to the first motor 21, the output end of the first motor 21 is fixedly connected to the gear 56, the gear 56 is meshed with the ring gear 22, the ring gear 22 is fixedly connected to the dovetail ring 23, the dovetail ring 23 is rotatably installed in the power shell 20, the ring gear 22 is fixedly connected to the synchronization ring 24, the synchronization ring 24 is fixedly connected to multiple groups of fixed frames 25, each group of fixed frames 25 is fixedly connected to a hydraulic box 26, and the hydraulic box 26 has a hydraulic chamber 27.

The hydraulic chamber 27 is slidably connected to a step rod 29, and the step rod 29 is fixedly connected to a special-shaped frame 30, and the special-shaped frame 30 is hinged to an articulated frame 31. Multiple groups of articulated frames 31 are jointly hinged to a group of coaxial frames 32, and the coaxial frames 32 are rotatably connected to an adapter 33. The power shell 20 is fixedly connected to a first active telescopic rod 34, and the moving end of the first active telescopic rod 34 is fixedly connected to the adapter 33. The first active telescopic rod 34 drives the adapter 33 to move, so that the adapter 33 drives the coaxial frame 32 to move, and the coaxial frame 32 drives the articulated frame 31 to move, so that the special-shaped frame 30 drives the step rod 29 to move. As the step rod 29 moves away from the first docking hole 18, under the pressure of the oil in the hydraulic chamber 27, the first pin 28 passes through the hole frame 7 and is inserted into the second docking hole 19. If the step rod 29 is inserted into the first docking hole 18, driven by the oil in the hydraulic chamber 27, the first pin 28 disengages from the hole frame 7 and the second docking hole 19, and when the first pin 28 connects the hole frame 7 and the second docking hole 19, the first motor 21 drives the gear 56 to rotate, and the rotating gear 56 drives the ring gear 22 to drive the synchronizer ring 24 to rotate, so that the synchronizer ring 24 drives the fixed frame 25 to rotate, so that the hydraulic box 26 drives the first pin 28 to rotate, thereby making the hole frame 7 and the plug-in block 17 rotate synchronously.

The dual-axis motor 36 drives the first screw 37 to rotate, and the rotating first screw 37 drives the clamping arm 38 to move along the bidirectional frame 35, thereby adjusting the spacing between the clamping arms 38. As the clamping arms 38 approach each other, the clamping arms 38 clamp the ring body 9, thereby limiting the movement of the ring body 9.

[0044] In one case of this embodiment, the cutting and sample making structure 13 includes two groups of cross frames 39, wherein one group of cross frames 39 is fixedly connected to a second motor 40, an output end of the second motor 40 is fixedly connected to a second screw 41, the second screw 41 is threadedly connected to a frame 42 that is slidably connected to one group of cross frames 39, the frame 42 is fixedly connected to a gear box 43, the gear box 43 is fixedly connected to a fourth motor 44, and two groups of bevel gears 45 that mesh with each other are rotatably installed in the gear box 43, wherein one group of bevel gears 45 is coaxially fixedly connected to the output shaft of the fourth motor 44, and the other group The bevel gear 45 is coaxially fixedly connected to a saw disk 46, and the thickness of the saw disk 46 is the same as the thickness of the cutting layer 47. Another set of cross frames 39 is fixedly connected to a third motor 48, and the output end of the third motor 48 is fixedly connected to a third screw 49.

A group of openings 53 are provided on the notched disk 52, and a waste hopper 54 fixedly connected to the notched disk 52 is provided below the opening 53. The second motor 40 drives the second screw 41 to rotate and the third motor 48 and the third screw 49 to rotate respectively, so that the frame 42 moves along one group of cross frames 39, and the lower bracket 50 moves along another group of cross frames 39, so that the lower bracket 50 moves to below the plug-in ring 15, and the frame 42 drives the gear box 43 to move, and the fourth motor 44 drives the bevel gear 45 to rotate. Under the action of the mutual engagement and transmission of the two groups of bevel gears 45, the saw disk 46 rotates and cuts the cutting layer 47 above the plug-in ring 15, so that the plug-in ring 15 falls into the waste hopper 54, and then the fifth motor 51 drives the notch disk 52 to rotate, and the frame 42 drives the gear box 43 away from the segmented storage part 11, and the multi-stage active telescopic frame 5 contracts, so that the sample tube 14 approaches the notch.

At this time, the sample volume in the sample tube 14 is the same and is the size of the space enclosed when the two ends of the sample tube 14 are closed. It is only necessary to measure in advance the volume when the two ends of the sample tube 14 are enclosed, and there is no need to measure the volume of each group of mud blocks separately. Since the same sample tube 14 is used, the mass of the sample tube 14 can also be measured in advance to eliminate the influence of the sample tube 14 on the weight measurement operation, and at the same time, the process of re-sampling the dug mud blocks is eliminated, which is convenient and quick.

[0045] In one aspect of this embodiment, the notched disc 52 is fixedly connected to a plurality of limiting rings 55 , wherein the inner diameter of the limiting rings 55 is larger than the outer diameter of the sample container 14 .

At this time, the outer cylinder 8, the ring body 9, the tubular drill bit 10, and the segmented storage part 11 rotate synchronously. The multi-stage active telescopic frame 5 contracts and the rotating connection part 6 drops, so that the rotating connection part 6 drives the hole frame 7 to move downward, so that the outer cylinder 8 and the tubular drill bit 10 drill into the soil layer. At this time, the drilled soil core enters the segmented storage part 11. As the multi-stage active telescopic frame 5 extends, the outer cylinder 8 and the tubular drill bit 10 are separated from the soil, and then the clamping ring structure 12 is used to clamp the ring body 9 to limit the outer cylinder 8 and the tubular drill bit 10, and the rotating connection part 6 is separated from the hole frame 7.

As the multi-stage active telescopic frame 5 is further extended, the rotating connecting part 6 takes the segmented storage part 11 out of the outer cylinder 8, and the second motor 40 drives the second screw 41 to rotate and the third motor 48 and the third screw 49 to rotate respectively, so that the frame 42 moves along one group of cross frames 39, and the lower bracket 50 moves along another group of cross frames 39, so that the lower bracket 50 moves to the bottom of the plug-in ring 15, and the frame 42 drives the gear box 43 to move, and the fourth motor 44 drives the bevel gear 45 to rotate, and the two groups of bevel gears 45 are meshed with each other. Under the action of the saw disk 46 and the transmission, the saw disk 46 rotates and cuts the cutting layer 47 above the plug-in ring 15, so that the plug-in ring 15 falls into the waste hopper 54, and then the fifth motor 51 drives the notched disk 52 to rotate, and the frame 42 drives the gear box 43 away from the segmented storage part 11, and the multi-stage active telescopic frame 5 contracts, so that the sample tube 14 approaches the disk surface of the notched disk 52, and as the cutting layer 47 on the sample tube 14 is cut off by the moving saw disk 46, the sample tube 14 and the sample in the sample tube 14 fall onto the notched disk 52 to cut out the sample, and then the frame 42 and the lower bracket 50 are reset, and then the above-mentioned cutting steps are repeated to cut each group of sample tubes 14 into the limiting rings 55 at each location of the notched disk 52, and the limiting rings 55 limit the sample tube 14 to complete the sample preparation operation.
