Description

Technical Field

Highway engineering structures include: subgrade, pavement, bridge, culvert, tunnel, drainage system, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. Before highway engineering construction, it is necessary to detect the foundation of the construction site, and the detection of rock and soil is an important method for measuring the foundation.

[0003] At present, the main method for detecting rock and soil in the prior art is to take the rock and soil from underground and then detect the properties of the rock and soil. At this time, a rock and soil sampling device is needed.

[0004] The existing rock and soil sampling devices usually rotate the sampling cylinder into the ground, so that the rock and soil enter the sampling cylinder for storage, and finally the sampling cylinder is pulled out to complete the sampling. Although the rock and soil can be sampled, there are still some deficiencies. In order to ensure that the drill pipe can be smoothly dug down, it is necessary to ensure the stability of the base when the device is used. In the prior art, the device is placed on the ground or simply inserted into the ground and relies on the gravity of the device itself to complete the stability.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: A portable sampling mechanism for geotechnical engineering investigation includes a base 1. A middle part of the base 1 is fixedly connected with an outer shell 2. A middle part of the outer shell 2 is slidably connected with a pressing rod 3. A bottom of the pressing rod 3 is fixedly connected with a pressing plate 20. A bottom of the pressing plate 20 is fixedly connected with a motor 24. An output end of the motor 24 is fixedly connected with a mounting plate 4. A bottom of the mounting plate 4 is fixedly connected with a sampling cylinder 5. By pressing the pressing rod 3, the pressing plate 20 can drive the motor 24, the mounting plate 4 and the sampling cylinder 5 to move downward simultaneously. At this time, the sampling cylinder 5 can be brought into contact with the ground. At the same time, by driving the motor 24, the sampling cylinder 5 can be rotated, and when the sampling cylinder 5 rotates, the sampling cylinder 5 can be moved downward, thereby completing the sampling work of the rock and soil.

[0033] Refer to Figures 2 - 4, a bottom plate 6 is fixedly connected to the middle of the base 1. A first compression spring 7 is fixedly connected inside the bottom plate 6. The other end of the first compression spring 7 is fixedly connected to a movable block 8. A cone 9 is fixedly connected to the side of the movable block 8 close to the first compression spring 7. The cone 9 is slidably connected to the middle of the bottom plate 6. A rotating rod 10 is slidably connected to the middle of the bottom plate 6. The bottom of the rotating rod 10 is fixedly connected to a housing 11. The housing 11 is in contact with the movable block 8. Arcs are provided on the sides of the clamping block 13 and the movable block 8 close to each other.

[0034] Refer to Figures 2 - 4 , by inserting the bottom plate 6 into the soil and pressing the rotating rod 10, when the rotating rod 10 moves downward, the housing 11 can move downward and contact the movable block 8. At this time, the arc provided can enable the housing 11 to quickly squeeze the movable block 8. At this time, the movable block 8 can eject the cone 9 out of the middle of the bottom plate 6 and support the bottom plate 6, which can improve the connection strength between the bottom plate 6 and the soil, and further improve the stability of the base 1, prevent the base 1 from tilting during use, avoid the need to refix the device, thereby reducing the time consumed for sampling and improving the sampling efficiency. At the same time, when the movable block 8 moves, the first compression spring 7 can be compressed. A locking component is fixedly connected inside the housing 11.

[0035] Refer to Figure 3 and Figure 4 , the locking component includes a second compression spring 12. The second compression spring 12 is fixedly connected inside the housing 11. The other end of the second compression spring 12 is fixedly connected to a clamping block 13. A clamping groove 14 is formed inside the bottom plate 6. The clamping block 13 and the clamping groove 14 are in plug-in fit. When the housing 11 moves downward, the clamping block 13 can move simultaneously. When the clamping block 13 moves to a position parallel to the clamping groove 14 and there is no external force extrusion, the clamping block 13 can be ejected into the clamping groove 14 by the second compression spring 12. At this time, the housing 11 can be fixed, thereby preventing the cone 9 from being retracted into the bottom plate 6 during use and enabling the cone 9 to continuously support the bottom plate 6.

[0036] Refer to Figure 3 and Figure 4 , a partition plate 21 is slidably connected inside the housing 11. The partition plate 21 is fixedly connected between the second compression spring 12 and the clamping block 13. The partition plate 21 can limit the clamping block 13 to prevent the clamping block 13 from tilting during movement, thereby avoiding the problem that the second compression spring 12 is deformed and damaged due to inclined extrusion, improving the service life of the second compression spring 12. A pull rope 15 is fixedly connected to the outside of the rotating rod 10. The other end of the pull rope 15 is fixedly connected to the side of the clamping block 13 close to the second compression spring 12.

[0037] Refer to Figure 3 and Figure 4, by rotating the rotating rod 10, the pulling rope 15 can be wound up. While the pulling rope 15 is being wound up, the clamping block 13 can be pulled out from the middle of the clamping groove 14, thereby releasing the restriction on the housing 11. At the same time, when the clamping block 13 moves, the second compression spring 12 can be compressed, and the second compression spring 12 can be used to make the clamping block 13 enter the clamping groove 14 again. At this time, by pulling the rotating rod 10 and under the action of the first compression spring 7, the housing 11 can move upward and complete the reset work. At the same time, under the action of the first compression spring 7, the movable block 8 can be extruded, and then the movable block 8 can drive the cone 9 to retract into the bottom plate 6 of the pile. At this time, the support for the bottom plate 6 of the pile can be quickly released, facilitating the removal of the base 1.

[0038] Refer to Figure 4 , a roller 22 is rotatably connected to the middle of the housing 11. The pulling rope 15 is in rolling contact with the roller 22. The pulling rope 15 can be restricted by the roller 22, thereby avoiding friction between the pulling rope 15 and the housing 11 during winding, improving the service life of the pulling rope 15. A handle is fixedly connected to the top of the rotating rod 10, and anti-slip grooves are provided on the outer side of the handle. The rotating rod 10 can be more conveniently operated through the handle and the anti-slip grooves, and the rotating rod 10 can be rotated effectively and comfortably at the same time.

[0039] Refer to Figure 2 and Figure 5 , two third compression springs 16 are fixedly connected inside the outer shell 2. The other ends of the third compression springs 16 are fixedly connected to a movable seat 17. A limiting block 18 is fixedly connected to the bottom of the movable seat 17. The limiting block 18 is slidably connected to the middle of the outer shell 2. Two limiting grooves 23 are provided inside the outer shell 2. The limiting block 18 is slidably connected to the middle of the limiting groove 23. The limiting block 18 can be limited by the limiting groove 23, thereby preventing the movable seat 17 from tilting during movement and enabling the pressing plate 20 to move up and down.

[0040] Refer to Figure 2 and Figure 5 , a connecting plate 19 is rotatably connected to the top of the movable seat 17. The connecting plate 19 is rotatably connected to the bottom of the pressing plate 20. When the pressing plate 20 moves downward, one side of the connecting plate 19 can be extruded. At this time, the connecting plate 19 can be flipped, and at the same time, under the action of the other side of the connecting plate 19, the movable seat 17 can be moved. When the movable seat 17 moves, the limiting block 18 can prevent the movable seat 17 from tilting during movement. At this time, the movable seat 17 can compress the third compression spring 16. After the sampling work is completed, by pulling the pressing rod 3 and under the action of the third compression spring 16, the movable seat 17 can move in the reverse direction. At this time, the pressing plate 20 can be extruded through the connecting plate 19 to make the pressing plate 20 move upward, enabling the employee to more conveniently take out the sampling cylinder 5 from the rock and soil, improving the sampling efficiency and reducing the labor intensity of the employee at the same time.

[0041] Working principle: When in use, by pressing the rotating rod 10, the housing 11 can squeeze the movable block 8, causing the movable block 8 to move. When the movable block 8 moves, the first compression spring 7 can be compressed and the cone 9 can be pushed out, thereby supporting the grounding plate 6 and improving the stability of the base 1. When the latch 13 moves to a position parallel to the card slot 14, under the action of the second compression spring 12, the latch 13 can be snapped into the card slot 14. At this time, the housing 11 can be fixed in the current position, preventing the cone 9 from being retracted into the grounding plate 6 during use. By rotating the rotating rod 10 and under the action of the pulling rope 15, the latch 13 and the card slot 14 can be separated. At this time, under the action of the first compression spring 7, the movable block 8 can squeeze the housing 11 and the cone 9 can be retracted, thereby releasing the support for the grounding plate 6 and facilitating the lifting of the base 1 to avoid the problem of the base 1 tilting during sampling.

[0042] Among them, by pressing the pressure rod 3, the pressure plate 20, the motor 24, the mounting plate 4, and the sampling cylinder 5 can move downward simultaneously. When the pressure plate 20 moves downward, the connecting plate 19 can be flipped, and the connecting plate 19 can drive the movable seat 17 and the limiting block 18 to move. When the movable seat 17 moves, the third compression spring 16 can be compressed. At this time, by driving the motor 24, the mounting plate 4 can drive the sampling cylinder 5 to rotate, thereby enabling the sampling cylinder 5 to perform sampling work. When the sampling cylinder 5 needs to be taken out, by pulling the pressure rod 3 and under the action of the third compression spring 16, the connecting plate 19 can squeeze the pressure plate 20, thereby facilitating and easily taking out the sampling cylinder 5 from the soil. At the same time, the time and energy consumed by employees during sampling can be reduced, and the sampling speed can be further improved.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
