Description

Technical Field

[0001] The utility model belongs to the field of road surface detection, and in particular relates to a sampling device for roadbed and road surface. Background Art

[0002] Roadbed refers to a strip structure built as the foundation of the road surface according to the route location and certain technical requirements. Its main function is to provide the necessary conditions for track or road paving, bear the road load, and transfer and diffuse the load deep into the foundation.

[0003] Existing roadbed and pavement compaction detection requires sampling of the road surface. For example, patent CN202321290576.7 discloses an intelligent device for intelligent compaction monitoring of roadbed and pavement. The device moves a collecting barrel to a designated location and then drives the collecting barrel to drill into the road surface for sampling.

[0004] The above technical solution has the following problems: To facilitate the movement of the collection barrel, a universal wheel structure is provided, which makes the entire device unstable during the sampling process. Furthermore, the sampling process is similar to drilling a hole in the road surface. Generally, a lubricant (coolant) is sprayed on the collection barrel to facilitate its penetration. After sampling, a large amount of waste liquid remains on the road surface, and a large amount of waste liquid enters the hole left by the sampling. The waste liquid on the road surface is easy to clean, but the waste liquid in the hole is more difficult to handle. Utility Model Content

[0005] In response to the deficiencies in the prior art, the present invention provides a sampling device for roadbed and pavement to solve the problem that a large amount of waste liquid generated during the sampling process remains on the pavement, and a large amount of waste liquid enters the holes left by sampling and is difficult to handle.

[0006] According to the embodiment of the present invention, the present invention adopts the following technical solutions:

[0007] The sampling device for roadbed and pavement includes a moving component, a sampling component and a supporting component. The moving component includes a base plate and a moving part installed at the lower end of the base plate; the sampling component includes a bracket installed on the base plate, a slide connected to the bracket along a vertical sliding manner, and a sampling part installed on the slide, and a through hole is opened on the base plate for the sampling part to pass through; the supporting component includes a slide connected in the through hole along a vertical sliding manner and a supporting ring fixed at the lower end of the slide, a sealing part for sealing the gap between the support ring and the pavement is provided at the bottom of the support ring, and a plurality of suction tubes are evenly distributed along the circumference of the side wall of the slide, one end of the suction tube is located on the inner side of the slide, and the other end of the suction tube extends to the outer wall of the slide and is connected to a pipe joint.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] In this solution, after the sampling component is moved to the designated position by the mobile component, the sampling component can be sampled on the road surface after it moves downward through the through hole. In order to ensure the stability of the sampling process, the slide is slid downward so that the support ring gradually rests on the road surface. The support ring supports the road surface, thereby reducing the movement of the moving component during the sampling component drilling into the road surface. In addition, the setting of the sealing component can seal the gap between the support ring and the road surface. The waste liquid generated during the sampling process is concentrated on the inner side of the slide, which can be absorbed by the pipette and then processed centrally. After the sampling is completed, the pipette can also be extended into the hole left by the sampling to suck out the waste liquid in the hole, which is convenient for the treatment of the waste liquid.

[0010] Furthermore, the inner wall of the slide is provided with an adjusting member for adjusting the position of the pipette, the adjusting member includes a slider connected to the inner wall of the slide in a vertical sliding direction, the outer wall of the pipette is provided with a ring, and the slider and the ring are detachably connected.

[0011] Furthermore, a limit ring is fixed on the pipette, and the limit ring is used to limit the movement range of the ring on the pipette.

[0012] Furthermore, a magnetic block is fixed to the bottom of the slide, and a magnetic ring for attracting the magnetic block is fixed to the free end of the pipette.

[0013] Furthermore, an annular gap is provided at the lower portion of the inner wall of the slide; the sealing member includes a sealing ring fixed on the support ring, and the sealing ring includes a first section filled in the annular gap and a second section extending to the lower end of the support ring.

[0014] Furthermore, a plurality of anti-wear rings coaxially arranged with the support ring are fixed to the lower end of the support ring, and the anti-wear rings are arranged on the outside of the sealing member.

[0015] Furthermore, a plurality of telescopic rods are hingedly connected to the outer wall of the slide cylinder along its circumference, and support plates are hingedly connected to the ends of the telescopic rods. The support plates and the support rings are detachably connected.

[0016] Furthermore, a connecting rod is movably connected to the support ring, and the connecting rod and the support plate are detachably connected. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described in detail below with reference to the accompanying drawings, and specific implementation methods will be given.

[0022] like Figure 1 、 Figure 2 、 Figure 3 As shown, the sampling device for roadbed and pavement includes a moving component, a sampling component and a supporting component. The moving component includes a base plate 1 and a moving part 2 installed at the lower end of the base plate 1. The moving part 2 uses a universal wheel structure with a foot brake in the existing technology to facilitate moving the base plate 1 and moving the sampling component to a designated position for sampling.

[0023] The sampling assembly includes a bracket 3 installed on the base plate 1, a slide plate 4 connected to the bracket 3 along the vertical sliding direction, and a sampling piece 5 installed on the slide plate 4. A through hole for the sampling piece 5 to pass through is opened on the base plate 1, and the bracket 3 is fixed on the base plate 1. A cylinder for driving the slide plate 4 to slide is installed on the bracket 3. By driving the slide plate 4 to slide vertically, the slide plate 4 drives the sampling piece 5 to slide vertically, so that the sampling piece 5 can contact the road surface and drill into the road surface for sampling. The specific principle and process of the sampling piece 5 drilling into the road surface and taking samples can be designed with reference to the road surface sampling equipment in the prior art, and no improvement is made in this embodiment.

[0024] The support assembly includes a slide 6 connected vertically to the through hole and a support ring 9 fixed to the lower end of the slide 6. A cylinder for driving the slide 6 to slide is installed on the base plate 1. By driving the slide 6 to slide upward, the support ring 9 and the road surface are not in contact, which facilitates the movement of the base plate 1. By driving the slide 6 downward, the support ring 9 is pressed against the road surface, increasing the friction between the support ring 9 and the road surface, thereby improving the stability of the sampling process to a certain extent. A number of anti-wear rings 13 are fixed to the lower end of the support ring 9, which are coaxially arranged with the support ring 9. The anti-wear rings 13 are made of silicone or other wear-resistant materials to increase the friction between the support ring 9 and the road surface.

[0025] A seal is provided at the bottom of the support ring 9 for sealing the gap between the support ring 9 and the road surface. The seal is arranged on the inner side of the anti-wear ring 13. Specifically, the seal includes a sealing ring 12 fixed to the support ring 9, and the sealing ring 12 is made of rubber. An annular gap 20 with a right-angled triangular cross-section is provided at the lower portion of the inner wall of the slide 6. The sealing ring 12 includes a first section 10 that fills the annular gap 20 and a second section 11 that extends to the lower end of the support ring 9. The provision of the first section 10 prevents waste liquid from entering the lower end of the support ring 9 through the gap between the inner side of the support ring 9 and the road surface, and as much waste liquid as possible is blocked on the inner side of the slide 6.

[0026] Several suction pipes 16 are evenly distributed along the circumference of the slide 6. One end of the suction pipe 16 is located on the inner side of the slide 6, and the other end of the suction pipe 16 extends to the outer wall of the slide 6 and is connected to a pipe joint 15. Specifically, the pipe joint 15 uses a conventional joint for pipe connection in the prior art. Through the setting of the pipe joint 15, it is convenient to connect the suction pipe 16 to other pipes or directly to the water pump, thereby facilitating the suction of waste liquid from the inside of the slide 6. After the sampling is completed, the suction pipe 16 can also be extended into the hole left by the sampling and the waste liquid in the hole can be sucked out, which is convenient for the treatment of the waste liquid.

[0027] During specific use, after the base plate 1 moves the sampling assembly to the designated position, the slide 6 is slid downward so that the support ring 9 rests on the road surface, the position of the pipette 16 in the slide 6 is moved to prevent the pipette 16 from affecting the sampling, and the pipette 16 is connected to the water inlet pipe of the water pump through the pipe joint 15, and then the slide 4 is slid downward, and sampling is carried out through the sampling piece 5, and at the same time, suction is carried out through the water pump. The waste liquid generated during the sampling process is blocked on the inside of the slide 6 and sucked out through the pipette 16. After the sampling is completed, the pipette 16 is extended into the hole left by the sampling and the waste liquid in the hole is sucked out.

[0028] In another embodiment of the present invention, the inner wall of the slide 6 is provided with an adjusting member for adjusting the position of the suction tube 16. The adjusting member includes a slider 17 vertically connected to the inner wall of the slide 6 for sliding. The slide 6 is installed with a cylinder for driving the slider 17 to slide. The pipette 16 is made of a flexible pipe, such as a plastic hose, so that the pipette 16 can be bent to a certain extent. The outer wall of the pipette 16 is provided with a ring 18. There is no connection between the ring 18 and the pipette 16, so that the ring 18 can move on the pipette 16. The slider 17 and the ring 18 are detachably connected. Specifically, the slider 17 and the ring 18 are bolted together. When the slider 17 slides up and down in the slide cylinder 6, the pipette 16 can be driven to move by the ring 18. When the slider 17 slides up, the middle part of the pipette 16 is also driven to move upward, so that the free end of the pipette 16 can remain in a drooping state but will not accumulate on the road surface to avoid obstructing sampling. When the pipette 16 needs to be inserted into the hole left by the sampling, the slider 17 is slid downward so that the free end of the pipette 16 can be further downward and inserted into the hole left by the sampling. A limiting ring 22 is fixed on the pipette 16 , and the limiting ring 22 is used to limit the movement range of the circular ring 18 on the pipette 16 . Specifically, two limiting rings 22 are provided and are respectively located on both sides of the circular ring 18 .

[0029] In another embodiment of the present invention, in order to prevent the free end of the pipette 16 from shaking randomly and affecting sampling after the middle part of the pipette 16 is suspended by the slider 17, a magnetic block 19 is fixed to the bottom of the slide 6, and a magnetic ring 21 for attracting the magnetic block 19 is fixed to the free end of the pipette 16. Through the mutual attraction between the magnetic block 19 and the magnetic ring 21, during the sampling process, the free end of the pipette 16 can be adsorbed at the position at the bottom of the slide 6, which does not affect the suction of the waste liquid and does not hinder the sampling. When it is necessary to suck the waste liquid in the hole left by the sampling, the end of the pipette 16 can be pulled into the hole.

[0030] In another embodiment of the present invention, a plurality of telescopic rods 8 are hingedly connected to the outer wall of the slide 6 along its circumference. The telescopic rods 8 can be selected from conventional electric telescopic rods or other rods with telescopic functions. The ends of the telescopic rods 8 are hingedly connected to support plates 7. By deflecting the telescopic rods 8 and adjusting their length, the support plates 7 can be brought into contact with the road surface. After deflecting the support plates 7, the support plates 7 can be pressed against the road surface. The telescopic rods 8 and support plates 7 are arranged along the circumference of the slide 6 to improve the support strength of the slide 6 on the road surface. Specifically, a connecting rod 14 is movably connected to the support ring 9. The connecting rod 14 and the support plate 7 are detachably connected. In this embodiment, one end of the connecting rod 14 is rotatably connected to the support ring 9, and the other end of the connecting rod 14 is bolted to the support plate 7. This design integrates the slide 6, support ring 9, telescopic rods 8, and support plate 7 into a stable triangular structure, and prevents the support plate 7 and telescopic rods 8 from deflecting on their own, thereby improving stability.
