Description

Technical Field

[0001] The present invention relates to the technical field of geological exploration, and more specifically, to a modular steep slope geological exploration device adapted to complex terrain. Background Art

[0002] Geological exploration plays a crucial role in human production and life. It is a process of exploring and researching underground resources and geological structures. In geological exploration work, drilling samples for testing is one of the important means to obtain underground geological information. Under conventional terrain conditions, existing geological exploration equipment and technologies have been relatively mature and can complete the drilling and sampling tasks relatively smoothly.

[0003] However, when facing geological exploration of some steep slopes, the situation becomes extremely complex and intractable. Especially in steep slopes with loose soil layers, the hole wall lacks support after drilling, resulting in easy collapse of the steep slope and inconvenient drilling and sampling. In view of this, we propose a modular steep slope geological exploration device adapted to complex terrain. Summary of the Invention

When the first rotating end does not rotate and the second rotating end rotates, the support sleeve mechanism rotates relative to the sampling mechanism to form a drilling and supporting motion state. When the support sleeve mechanism is separated from the sampling mechanism, the support sleeve mechanism supports the drill hole on the steep slope. The support sleeve mechanism includes an inner pipe, the inner pipe is threadedly connected to the threaded column, a connecting ring is fixedly arranged at the top end of the inner pipe, an outer pipe is fixedly arranged on the outer edge surface of the connecting ring, and a plurality of threaded plates are annularly and equidistantly arranged in the gap between the inner pipe and the outer pipe.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. When the sampling mechanism and the support sleeve mechanism of the present invention rotate as a whole, a drilling and sampling motion state is formed. When the support sleeve mechanism rotates relative to the sampling mechanism, a drilling and support motion state is formed. And when the support sleeve mechanism rotates relative to the sampling mechanism, the support sleeve mechanism rotates and moves downward relative to the threaded column to continue drilling into the soil layer. After sampling, the support sleeve mechanism remains in the soil layer. The outer tube provides support for the drilled hole wall to prevent the steep slope from collapsing due to the lack of support for the hole wall after drilling. And the inner tube provides support for the outer tube through a plurality of threaded plates, improving the support strength of the outer tube. And in the drilling and support motion state and the drilling and sampling motion state of the support sleeve mechanism, the whole of it moves downward, and the soil is sent into the plurality of threaded cavities formed by the inner tube, the plurality of threaded plates and the outer tube through the spiral guide surface of the threaded plates, further improving the support strength of the support sleeve mechanism, and solving the technical problem of inconvenient drilling and sampling of the geological exploration device for the steep slope.

[0019] 2. Through the structural design of the sampling mechanism of the present invention, the circular plate is used as the first rotating end, and its rotation can drive the fixed shaft to rotate, so that the sampling mechanism rotates. After the sampling mechanism completes drilling and sampling, by rotating the adjusting ring, a plurality of cutting blocks can be made to enclose a partition plate, so that the sample in the sampling cavity is isolated from the loose soil layer of the side steep slope, preventing the sample in the sampling cavity from leaking, and further making sampling convenient.

[0020] 3. Through the structural design of the guide ring, the cross-section of the guide ring is set as a right triangle, which can divert the soil layer. The columnar soil layer located at the center passes through the inner hole of the guide ring, and the annular soil layer located on the outside passes through the gap between the guide ring and the outer pipe to form a compaction cavity. After compaction, it enters the threaded cavity, thereby improving the compactness of the soil and further enhancing the support strength of the support sleeve mechanism, making the hole wall less likely to collapse after drilling.

[0021] 4. Through the design of the adjusting ring and the guide ring, the rotation of the guide ring can drive the adjusting ring through the insertion block. When in the drilling support movement state, the support sleeve mechanism rotates and moves downward relative to the threaded column. When the insertion block is disengaged from the insertion hole, several cutting blocks enclose a partition board. During the installation process of the support sleeve mechanism, the top surface of the guide ring first contacts the bottom end of the insertion block. Since the sample in the sampling cavity needs to be rotated by the adjusting ring to reset the cutting block, until the threaded column is installed, the flange ring B and the flange ring A are fixed by bolts using tools. And at this time, the insertion hole is exactly corresponding to the position of the insertion block. Under the elastic force of the spring C, the insertion block is inserted into the insertion hole to complete the installation, which is convenient for installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] As Figures 1 to 19 shown, a modular steep slope geological exploration device adapted to complex terrains according to the present invention includes a climbing vehicle 1, an angle adjusting mechanism 2, a lifting mechanism 3, a rotating mechanism 4, a sampling mechanism 5 and a support sleeve mechanism 6.

[0056] The angle adjusting mechanism 2 is fixedly arranged on the climbing vehicle 1;

[0057] The lifting mechanism 3 is fixedly arranged at the movable end of the angle adjusting mechanism 2; The climbing vehicle 1, the angle adjusting mechanism 2 and the lifting mechanism 3 are all prior arts and will not be elaborated here.

[0058] The rotating mechanism 4 includes a mounting seat 41, a rotating drive assembly 42, a one-way rotating assembly A 43 and a one-way rotating assembly B 44;

[0059] The mounting seat 41 is fixedly arranged at the movable end of the lifting mechanism 3, and a rotating groove A 411 is opened at the bottom end of the mounting seat 41, and a rotating groove B 412 is opened at the top end of the rotating groove A 411.

[0060] The rotation drive assembly 42 includes a motor 421, a coupling A 422, and a gear ring 424; the motor 421 is fixedly arranged at the top end of the mounting seat 41, the coupling A 422 is rotatably arranged on the mounting seat 41, the top end of the coupling A 422 is fixedly connected to the output shaft of the motor 421, the bottom end of the coupling A 422 penetrates into the rotating groove A 411 and is fixedly provided with an internal gear 423, the gear ring 424 is rotatably arranged on the rotating groove A 411, the gear ring 424 and the internal gear 423 are meshed and connected through a side gear 425, a coupling B 426 is fixedly arranged on the side gear 425, a connecting pipe 427 is fixedly arranged at the bottom end of the gear ring 424, a circular plate 420 is rotatably arranged in the connecting pipe 427, the top end of the circular plate 420 is rotatably connected to the bottom end of the coupling B 426, a flange ring A 428 is fixedly arranged at the bottom end of the connecting pipe 427, a flange ring B 429 is fixed to the flange ring A 428 through a plurality of bolts, and a plurality of arc plates 4210 are fixedly arranged at equal intervals in a ring shape at the bottom end of the flange ring B 429.

[0061] The one-way rotation assembly A 43 includes a limit ring A 431, the limit ring A 431 is fixedly arranged on the rotating groove B 412, a rotating ring 432 is rotatably connected inside the limit ring A 431, at least one arc groove A 433 is formed on the outer edge surface of the rotating ring 432, the groove depth of the arc groove A 433 gradually becomes smaller in the clockwise direction, a reverse limit cavity A is formed by the gap between the arc groove A 433 and the rotating ring 432, a limit post A 434 is movably arranged in the reverse limit cavity A, the limit post A 434 and the deep part of the arc groove A 433 are elastically connected through a spring A 435, and a circular groove A 436 is formed at the bottom end of the rotating ring 432. Through the structural design of the one-way rotation assembly A 43 in the present invention, under the elastic force of the spring A 435, both ends of the limit post A 434 are in contact with the arc groove A 433 and the rotating ring 432 respectively. Since the limit post A 434 cannot move towards the narrow part of the reverse limit cavity, when the rotating ring 432 has a force tending to rotate reversely, the limit ring A 431 locks the rotating ring 432 through the limit post A 434. Therefore, the rotating ring 432 can only rotate in the forward direction and cannot rotate reversely.

[0062] The one-way rotation assembly B 44 includes a limit ring B 441, the limit ring B 441 is fixedly arranged on the circular groove A 436, a rotating block 442 is rotatably connected inside the limit ring B 441, the bottom end of the rotating block 442 is fixedly connected to the top end of the coupling B 426, at least one arc groove B 443 is formed on the outer edge surface of the rotating block 442, a reverse limit cavity B is formed by the gap between the arc groove B 443 and the limit ring B 441, a limit post B 444 is movably arranged in the reverse limit cavity B, and the limit post B 444 and the deep part of the arc groove B 443 are elastically connected through a spring B 445.

[0063] The principle of the one-way rotation assembly B 44 of the present invention is the same as that of the one-way rotation assembly A 43, and the rotating block 442 can only rotate in the forward direction and cannot rotate reversely. It is worth mentioning that due to the Figure 17It is a bottom view, so the depth of the arc groove A433 seems to gradually increase in the clockwise direction. Through the structural design of the rotating mechanism 4 of the present invention, when the motor 421 is controlled to rotate forward by an external control mechanism, the coupling shaft A422 drives the internal gear 423 to rotate forward. Since the rotating block 442 cannot rotate backward, the coupling shaft B426 and the side gear 425 cannot rotate backward. Then, the internal gear 423 drives the circular plate 420, the rotating ring 432 and the toothed ring 424 to rotate forward as a whole through the coupling shaft B426 and the side gear 425, so that a plurality of arc plates 4210 rotate forward. When the motor 421 is controlled to rotate backward by an external control mechanism, the coupling shaft A422 drives the internal gear 423 to rotate backward. Since the rotating ring 432 cannot rotate backward, the internal gear 423 drives the side gear 425 to rotate forward, so that the toothed ring 424 still rotates forward.

[0064] The sampling mechanism 5 includes a fixed shaft 50, the fixed shaft 50 is fixed at the bottom end of the circular plate 420, a threaded column 51 is fixed at the bottom end of the fixed shaft 50, a sampling cavity 52 is opened at the bottom end of the threaded column 51, a circular groove B53 is opened at the bottom end of the sampling cavity 52, a fixed ring 54 is fixed at the top end of the circular groove B53, a plurality of inclined grooves 55 are annularly and equally spaced at the bottom end of the fixed ring 54, an adjusting ring 56 is rotatably arranged at the bottom end of the circular groove B53, a plurality of centripetal grooves 57 are annularly and equally spaced at the top end of the adjusting ring 56, and a plurality of cutting blocks 58 are arranged in the gap between the adjusting ring 56 and the fixed ring 54. The number of the plurality of cutting blocks 58, the plurality of centripetal grooves 57 and the plurality of inclined grooves 55 is equal. An activity column 59 is arranged on the cutting block 58, and both ends of the activity column 59 are movably connected with the centripetal groove 57 and the inclined groove 55 respectively;

[0065] When a plurality of activity columns 59 move to the centripetal end of the inclined groove 55, a plurality of cutting blocks 58 enclose a partition board. Through the structural design of the sampling mechanism 5 of the present invention, the circular plate 420 serves as the first rotating end, and its rotation can drive the fixed shaft 50 to rotate, so that the sampling mechanism 5 rotates. After the sampling mechanism 5 drills and samples, by rotating the adjusting ring 56, a plurality of cutting blocks 58 can enclose a partition board, so that the sample in the sampling cavity 52 is isolated from the loose soil layer on the side steep slope, preventing the sample in the sampling cavity 52 from leaking, and further making the sampling convenient.

[0066] An activity groove 561 is opened at the bottom end of the adjusting ring 56, a plug-in block 562 is movably arranged in the activity groove 561, an empty groove 563 is opened at the top end of the plug-in block 562, and the bottom end of the empty groove 563 and the top end of the activity groove 561 are elastically connected by a spring C564. Through the above design of the present invention, under the elastic action of the spring C564, the plug-in block 562 is located at the bottom end of the activity groove 561.

[0067] The cutting block 58 includes a connecting portion 581. The movable post 59 is rotatably arranged on the connecting portion 581. A cutting portion 582 is fixedly arranged at the centripetal end of the connecting portion 581. The cutting portion 582 has a triangular structure, and any two adjacent cutting portions 582 are slidably connected. Through the design of the cutting block 58 in the present invention, when a plurality of movable posts 59 move in the inclined slots 55, the centripetal ends of the plurality of cutting blocks 58 form a closed cutting structure, preventing the sample from entering the gap between the adjusting ring 56 and the fixed ring 54 during sampling.

[0068] The support sleeve mechanism 6 includes an inner tube 61. The inner tube 61 is threadedly connected to the threaded post 51. A connecting ring 62 is fixedly arranged at the top end of the inner tube 61. An outer tube 63 is fixedly arranged on the outer edge surface of the connecting ring 62. A plurality of insertion slots 631 are annularly and equidistantly arranged at the top end of the outer tube 63. The plurality of insertion slots 631 are respectively inserted and matched with the plurality of arc plates 4210. A plurality of threaded plates 64 are annularly and equidistantly arranged in the gap between the inner tube 61 and the outer tube 63. Both ends of the threaded plate 64 are fixedly connected to the inner tube 61 and the outer tube 63 respectively. Through the above settings in the present invention, the gap between any two adjacent threaded plates 64 forms a conveying channel, and the plurality of arc plates 4210 serve as the second rotating end, and their rotation can drive the outer tube 63 to rotate, so that the support sleeve mechanism 6 rotates. When the external control structure controls the motor 421 to rotate forward, the sampling mechanism 5 and the support sleeve mechanism 6 form a drilling and sampling motion state when rotating as a whole. When the external control structure controls the motor 421 to rotate reversely, the support sleeve mechanism 6 forms a drilling and supporting motion state when rotating relative to the sampling mechanism 5. And when the support sleeve mechanism 6 rotates relative to the sampling mechanism 5, the support sleeve mechanism 6 rotates and moves downward relative to the threaded post 51 to continue drilling into the soil layer. After sampling, the support sleeve mechanism 6 remains in the soil layer. The outer tube 63 provides support for the drilled hole wall to prevent the steep slope from collapsing due to the lack of support for the hole wall after drilling. And the inner tube 61 provides support for the outer tube 63 through the plurality of threaded plates 64, improving the support strength of the outer tube 63. And in the drilling and supporting motion state and the drilling and sampling motion state of the support sleeve mechanism 6, it moves downward as a whole, and the soil is sent into the plurality of threaded cavities formed by the inner tube 61, the plurality of threaded plates 64 and the outer tube 63 through the spiral guide surface of the threaded plate 64, further improving the support strength of the support sleeve mechanism 6, and solving the technical problem of inconvenient drilling and sampling of the geological exploration device for the steep slope.

[0069] A guide ring 611 is fixedly installed at the bottom end of the inner tube 61. The cross-section of the guide ring 611 is a right triangle. The gap between the guide ring 611 and the outer tube 63 forms a compaction cavity. An insertion hole 612 is opened at the top end of the guide ring 611, and the insertion block 562 is inserted and matched with the insertion hole 612. Through the structural design of the guide ring 611 in the present invention, the rotation of the guide ring 611 can drive the adjustment ring 56 through the insertion block 562. When in the drilling and supporting motion state, the support sleeve mechanism 6 rotates and moves downward relative to the threaded column 51. When the insertion block 562 is separated from the insertion hole 612, several cutting blocks 58 surround to form a partition board. The cross-section of the guide ring 611 is designed as a right triangle to divert the soil layer. The columnar soil layer located at the central position passes through the inner hole of the guide ring 611, and the annular soil layer located on the outside passes through the gap between the guide ring 611 and the outer tube 63 to form a compaction cavity, and after being compacted, enters the threaded cavity, thereby improving the compactness of the soil, and further improving the support strength of the support sleeve mechanism 6, making the hole wall after drilling less likely to collapse.

[0070] Working principle: This embodiment provides a modular steep slope geological exploration device adapted to complex terrains. When in use, the remote control climbing vehicle 1 is moved to an appropriate position, and the motor 421 is controlled to rotate forward through an external control structure. The movable end of the external control lifting mechanism 3 descends, so that the sampling mechanism 5 and the support sleeve mechanism 6 rotate integrally. The soil layer is diverted by the guide ring 611. The columnar soil layer located at the central position enters the sampling cavity 52 through the inner hole of the guide ring 611, and the annular soil layer located on the outside passes through the gap between the guide ring 611 and the outer tube 63 to form a compaction cavity, and after being compacted, enters the threaded cavity, thereby improving the compactness of the soil, and further improving the support strength of the support sleeve mechanism 6 until the sampling is completed;

[0071] The motor 421 is controlled to rotate reversely through an external control structure. When the support sleeve mechanism 6 rotates relative to the sampling mechanism 5, a drilling and supporting motion state is formed. The movable end of the external control lifting mechanism 3 is raised, so that the sampling mechanism 5 rises, while the support sleeve mechanism 6 continues to drill. The support sleeve mechanism 6 rotates and moves downward relative to the threaded column 51. When the insertion block 562 is separated from the insertion hole 612, several cutting blocks 58 surround to form a partition board, so that the sample in the sampling cavity 52 is isolated from the loose soil layer on the side steep slope, preventing the sample in the sampling cavity 52 from leaking. The columnar soil layer located at the central position enters the inner tube 61 through the inner hole of the guide ring 611, and the annular soil layer located on the outside passes through the gap between the guide ring 611 and the outer tube 63 to form a compaction cavity, and after being compacted, enters the threaded cavity, until the support sleeve mechanism 6 drills into the steep slope, the compacted soil completely fills the threaded cavity, the sampling mechanism 5 is separated from the support sleeve mechanism 6, the sampling is completed, the support sleeve mechanism 6 remains in the soil layer, and the outer tube 63 provides support for the drilled hole wall;

[0072] Installation of the support sleeve mechanism 6: Use a tool to remove the bolts, remove the flange ring B429 and several arc plates 4210 from the flange ring A428, take out the new support sleeve mechanism 6, insert the several arc plates 4210 into the several insertion slots 631 respectively, and rotate the support sleeve mechanism 6 along the threaded column 51. During this process, the top surface of the guide ring 611 comes into contact with the bottom end of the insertion block 562 first. Since the cutting block 58 needs to be reset by rotating the adjusting ring 56 when taking out the sample in the sampling cavity 52, until the threaded column 51 is completely installed, use a tool to fix the flange ring B429 and the flange ring A428 with bolts. And at this time, the insertion hole 612 is exactly corresponding to the position of the insertion block 562. Under the elastic force of the spring C564, the insertion block 562 is inserted into the insertion hole 612 to complete the installation.
