Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically a core drilling device for geological exploration. Background Technology

[0002] Geological exploration is the investigation and research activity that uses various means and methods to explore and detect underground rock and soil masses, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It involves investigating and researching the geological conditions of a specific area, including rocks, strata, structures, minerals, hydrology, and geomorphology, to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and to provide the necessary mineral reserves and geological data for mine construction design.

[0003] Geological exploration core sampling is generally carried out in the field and requires the sample to be pulled to the sampling area using rollers. However, the rollers can cause shaking during the core sampling process, which can lead to a shift in the core sampling position and affect the quality of the sample analysis after sampling. Utility Model Content

[0004] The purpose of this invention is to provide a drilling core sampling device for geological exploration, which aims to solve the problem that the rollers are prone to shaking when in contact with the ground during the drilling core sampling process in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the drilling and coring device for geological exploration includes a drilling machine, the lower part of which is mounted on a base;

[0006] The base is provided with an inner cavity, and four sets of alternating lifting components are provided in the inner cavity. The four sets of alternating lifting components are arranged in a rectangular array. A driving device is fixedly provided in the base, and the output end of the driving device is connected to four sets of transmission components through a transmission component.

[0007] The alternating lifting assembly includes a limiting slide plate fixed to the inner wall of the base and extending in the vertical direction, an inner lifting plate and an outer lifting plate adapted to slide vertically and vertically on the limiting slide plate, and each transmission component is connected to the corresponding outer lifting plate so that the outer lifting plate can move vertically within the limiting slide plate.

[0008] The inner lifting plate is provided with a support plate, the outer lifting plate is provided with casters, and the bottom of the base is provided with a through hole for the support plate and casters to pass through.

[0009] The limiting slide plate is equipped with a gear that rotates between the inner lifting plate and the outer lifting plate. Both the inner and outer lifting plates are fixed with racks extending in the vertical direction on the side facing the gear. The gear meshes with the two racks to make the inner and outer lifting plates move in opposite directions, thereby causing the support plate and the universal wheel to alternately pass through the base to support the base.

[0010] Preferably, the transmission component includes a rotating plate, a plug-in post, and a closed limiting ring. The end of the plug-in post away from the rotating plate is inserted into the closed limiting ring and can reciprocate horizontally relative to the closed limiting ring, so that when the rotating plate rotates, the plug-in post drives the closed limiting ring to move horizontally up and down.

[0011] The plug is fixed on the side of the rotating plate facing the outer lifting plate;

[0012] The closed limiting ring is fixed to the outer lifting plate.

[0013] Preferably, the slide rail of the limiting slide plate has a concave cross-sectional shape, and the inner lifting plate and the outer lifting plate have a convex shape that matches the concave shape on the side near the limiting slide plate.

[0014] Preferably, the output end of the drive device is fixedly provided with a first bevel gear, and the first bevel gear meshes with a second bevel gear;

[0015] The rotating plate is connected to the second bevel gear for transmission.

[0016] Preferably, a fixing frame is fixed on the limiting slide plate; a round rod extending in the front-rear direction is fixed on the adjacent fixing frame;

[0017] The second bevel gear is mounted on the round rod;

[0018] The rotating plate is fixed to the round rod;

[0019] The transmission assembly includes a round rod, a first bevel gear, and a second bevel gear.

[0020] Preferably, an outer horizontal plate extending in the left-right direction is fixedly provided on the outer lifting plate, and a short rod is fixedly provided at the lower end of the outer horizontal plate, and the lower end of the short rod is fixedly connected to the top of the universal wheel.

[0021] Preferably, an inner horizontal plate extending in the left-right direction is fixedly provided on the inner lifting plate, and a storage frame with an opening facing downward is fixedly provided at the lower end of the inner horizontal plate.

[0022] The storage frame is equipped with a self-adjusting component, which is connected to the support plate.

[0023] Preferably, the self-adjusting component includes a lifting column that moves vertically along the storage frame, a vertical screw that is threadedly adapted to the lifting column and extends in the vertical direction, and a knob that is drivenly connected to the vertical screw.

[0024] The top of the vertical lead screw is rotatably mounted on the inner top wall of the storage frame;

[0025] The support plate is located at the bottom of the lifting column, and the knob is located on the outside of the storage frame.

[0026] Preferably, a connecting rod is fixedly provided on the knob, the connecting rod passes through the storage frame and is fixedly connected to a third bevel gear, and a fourth bevel gear that meshes with the third bevel gear is fixedly provided on the vertical lead screw.

[0027] Preferably, a level is mounted on the upper surface of the base.

[0028] The beneficial effects are: 1. When using this equipment, the support plate must first be finely adjusted. This adjustment allows the casters to retract while the support plate extends beyond the base, preventing excessive vertical swaying of the base. Next, the drive unit is activated, indirectly causing the rotating plate to rotate. This causes the inner and outer lifting plates to move in opposite directions. This ensures that while the casters retract into the base, the support plate remains firmly supported on the ground. In this way, the support plate provides excellent stability to the base. It's important to understand that if the equipment shakes during core sampling, the core sampling position may shift, negatively impacting the final test results.

[0029] 2. When the support plate supports the ground to provide stable support for the base, there is a situation where the ground may not be flat and smooth, but rather uneven. In this case, the self-adjusting component can precisely adjust the elongation of the support plate to accommodate the unevenness of the ground. Through this adjustment, the support plate can better conform to the ground, maintaining effective contact with the ground regardless of its undulations, thus stably supporting the base. This design greatly improves the practicality of the entire device, enabling it to operate normally in various complex ground environments without being affected by uneven ground in terms of supporting stability of the base.

[0036] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0037] like Figures 1-5 As shown, a drilling core sampling device for geological exploration is mainly used to move the drilling core sampling device to the core sampling area via universal wheels 7. At the same time, universal wheels 7 are retracted into the base 2, and support plates 6 extend out from the base 2. Universal wheels 7 and support plates 6 alternately extend out from the base 2 to support the ground, so that the base 2 can be stable, thereby enabling the drilling machine 1 to perform core sampling stably and improve the accuracy of core sampling.

[0038] In this embodiment, the core drilling device includes a drilling machine 1, which is mounted on a base 2. The structure and principle of the drilling machine 1 are existing technologies and will not be described in detail here.

[0039] The base 2 provides support for the drilling machine 1, making it easier to use.

[0040] like Figures 2-5 As shown, the base 2 has an inner cavity containing four sets of alternating lifting components 3 arranged in a rectangular array. A drive device 4 is fixedly installed in the base 2. In this embodiment, the drive device 4 is a dual-head motor. The structure and principle of the dual-head motor are existing technologies and will not be described in detail here. The output end of the drive device 4 is connected to four sets of transmission components 5 through a transmission component. After the drive device 4 is started, it can drive the four sets of transmission components 5 to rotate through the transmission component.

[0041] Specifically, the transmission component 5 includes a rotating plate 501, a plug-in post 502, and a closed limiting ring 503. The end of the plug-in post 502 away from the rotating plate 501 is inserted into the closed limiting ring 503. The plug-in post 502 is fixed on the rotating plate 501 and inserted into the closed limiting ring 503, and can move horizontally back and forth relative to the closed limiting ring 503. When the rotating plate 501 rotates, the plug-in post 502 drives the closed limiting ring 503 to move horizontally up and down. When the rotating plate 501 rotates, it can drive the plug-in post 502 to move in the inner ring of the closed limiting ring 503, thereby driving the closed limiting ring 503 to move.

[0042] like Figure 3 As shown, when the closed limit ring 503 moves, it can drive the alternating lifting assembly 3 to move the support plate 6 and the universal wheel 7 in opposite directions.

[0043] Specifically, the alternating lifting assembly 3 includes a limiting slide plate 301 fixed to the inner wall of the base 2 and extending in the vertical direction, an inner lifting plate 302 and an outer lifting plate 303 adapted to slide vertically and vertically along the limiting slide plate 301. Each closed limiting ring 503 is fixed on the corresponding outer lifting plate 303. When the closed limiting ring 503 moves, it can drive the outer lifting plate 303 to move vertically along the limiting slide plate 301. In this embodiment, the slide cross-section of the limiting slide plate 301 is a U-shaped structure. The inner lifting plate 302 and the outer lifting plate 303 have a convex structure adapted to the U-shaped structure on the side near the limiting slide plate 301. By setting the U-shaped and convex structures, the inner lifting plate 302 and the outer lifting plate 303 will not deviate during the vertical movement along the limiting slide plate 301, thus improving the transmission effect.

[0044] The output end of the drive device 4 is fixedly provided with a first bevel gear 8, which meshes with a second bevel gear 11. A fixed frame 9 is fixed on the limiting slide plate 301. A round rod 10 extending in the front-back direction is fixed on the adjacent fixed frame 9. A round rod 10 extending in the front-back direction is fixed on the second bevel gear 11. When the drive device 4 is started, it can drive the first bevel gear 8 to rotate. Since the first bevel gear 8 meshes with the second bevel gear 11, it can drive the second bevel gear 11 to rotate, which in turn drives the round rod 10 to rotate. The rotation of the round rod 10 can drive the rotating plate 501 to rotate. The transmission component includes the round rod 10, the first bevel gear 8, and the second bevel gear 11.

[0045] In this embodiment, the fixing frame 9 can support the round rod 10 and prevent the round rod 10 from shaking during transmission.

[0046] like Figure 2 and Figure 3As shown, when the outer lifting plate 303 moves up and down along the limiting slide plate 301, it can drive the inner lifting plate 302 to move up and down along the limiting slide plate 301, so as to realize that the inner lifting plate 302 and the outer lifting plate 303 move in opposite directions, thereby allowing the support plate 6 and the universal wheel 7 to alternately pass through the base 2 to support the base 2.

[0047] Specifically, a gear 12 is rotatably mounted on the limiting slide plate 301. The gear 12 is located between the inner lifting plate 302 and the outer lifting plate 303. Both the inner lifting plate 302 and the outer lifting plate 303 have racks 13 extending in the vertical direction fixed on the side facing the gear 12. The gear 12 meshes with the two racks 13. When the outer lifting plate 303 moves up and down, it can drive the racks 13 on the outer lifting plate 303 to move up and down, thereby driving the gear 12 to rotate. When the gear 12 rotates, it can drive the inner lifting plate 302 to move up and down through the meshing of the gear 12 with the racks 13 on the inner lifting plate 302, so that the inner lifting plate 302 and the outer lifting plate 303 move in opposite directions.

[0048] like Figure 4 and Figure 5 As shown, an outer horizontal plate 14 extending in the left-right direction is fixedly mounted on the outer lifting plate 303. A short rod is fixedly mounted on the lower end of the outer horizontal plate 14, and the lower end of the short rod is fixedly connected to the top of the caster wheel 7. An inner horizontal plate 15 extending in the left-right direction is fixedly mounted on the inner lifting plate 302. A storage frame 16 with an opening facing downward is fixedly mounted on the lower end of the inner horizontal plate 15. An autonomous adjustment component 17 is provided inside the storage frame 16. The autonomous adjustment component 17 is connected to the support plate 6. A through hole is provided at the bottom of the base 2 for the support plate 6 and the caster wheel 7 to pass through. A closing door is provided on the base 2. After the closing door is opened, the support plate 6 can be finely adjusted inside the base 2.

[0049] In this embodiment, before the drive device 4 is started, the support plate 6 can be finely adjusted inside the base 2 so that while the caster 7 is retracted into the base 2, the support plate 6 has extended out of the base 2, thus preventing the base 2 from falling when the support plate 6 and the caster 7 are alternating.

[0050] Specifically, the self-adjusting component 17 includes a lifting column 1701 that moves vertically along the storage frame 16, a vertical lead screw 1702 that is threadedly adapted to the lifting column 1701 and extends in the vertical direction, and a knob 1703 that is drivenly connected to the vertical lead screw 1702; the top of the vertical lead screw 1702 is rotatably mounted on the inner top wall of the storage frame 16; the support plate 6 is located at the bottom of the lifting column 1701, and the knob 1703 is located on the outside of the storage frame 16.

[0051] A connecting rod is fixedly installed on the knob 1703. The connecting rod passes through the storage frame 16 and is fixedly connected to the third bevel gear 19. A fourth bevel gear 20 that meshes with the third bevel gear 19 is fixedly installed on the vertical screw 1702. When the operator opens the closed door, he rotates the knob 1703 inside the base 2, so that the knob 1703 can drive the third bevel gear 19 to rotate through the connecting rod. Since the third bevel gear 19 meshes with the fourth bevel gear 20, the fourth bevel gear 20 can drive the vertical screw 1702 to rotate, so that the lifting column 1701 can move up and down along the storage frame 16, thereby realizing the fine adjustment of the support plate 6.

[0052] In this embodiment, after the support plate 6 extends out of the base 2, the extension of the support plate 6 needs to be adjusted again to suit the uneven ground. The above operation is repeated to adjust the support plate 6.

[0053] like Figure 1 As shown, a level 21 is mounted on the upper surface of the base 2. The level 21 is designed to observe whether the device is stable and to determine whether further adjustments are needed.

[0054] Working principle: When in use, the device is moved to the core extraction area by the casters 7. In this embodiment, the core extraction area is pre-planned and belongs to the prior art, so it will not be described in detail here. Then, the closed door is opened and the knob 1703 is manually turned. The knob 1703 can indirectly drive the vertical screw 1702 to rotate through the connecting rod, so that the lifting column 1701 moves up and down along the storage frame 16, and the extension of the support plate 6 can be finely adjusted.

[0055] Then the drive device 4 is started, which can drive the first bevel gear 8 to rotate. Since the first bevel gear 8 meshes with the second bevel gear 11, it can drive the second bevel gear 11 to rotate, which in turn drives the round rod 10 to rotate. When the round rod 10 rotates, it can drive the rotating plate 501 to rotate. When the rotating plate 501 rotates, it can drive the insertion post 502 to move in the inner ring of the closed limiting ring 503, so as to drive the outer lifting plate 303 to move up and down along the limiting slide plate 301. When the outer lifting plate 303 moves up and down, it can drive the rack 13 on the outer lifting plate 303 to move up and down, which drives the gear 12 to rotate. When the gear 12 rotates, it meshes with the rack 13 on the inner lifting plate 302, thereby driving the inner lifting plate 302 to move up and down, so that the inner lifting plate 302 and the outer lifting plate 303 move in opposite directions, thereby causing the support plate 6 and the universal wheel 7 to alternately pass through the base 2 to alternately support the base 2.

[0056] After the support plate 6 extends out of the base 2 and is supported on the ground, the operator can turn the knob 1703 again. The knob 1703 indirectly drives the vertical screw 1702 to rotate, just like the above operation, to adjust the extension of the four sets of support plates 6. This is suitable for uneven ground and improves practicality.

[0057] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
