Description

Technical Field

[0001] The present invention relates to the field of core sampling equipment, and specifically to a field portable rock plug sample collection device and method. Background Art

[0002] During field geological scientific investigations, geological surveyors usually need to hike into mountainous areas, jungles, canyons and other areas with complex terrain and landforms, and collect fresh rock plug samples on-site at the outcrop positions of geological profiles for determining the physical properties and reservoir physical properties of rocks under geological conditions. Some of the rock outcrop samples in the field profile are large in volume and weight and difficult to move, and it is necessary to drill plug samples in-situ inside large rock samples. In addition, some rock outcrop samples have undergone long-term weathering and infiltration of atmospheric precipitation, and have low degree of consolidation, making it difficult to obtain complete rock plug samples. In addition, during field on-site operations, it is difficult to use collection and sample preparation devices equipped with driving forces such as electricity and fuel. At present, rock plug samples are usually drilled on-site in the field by a hand-held battery drill. During the drilling process, the operator needs to hold the drill bit against a plane of a large rock and then push the drill bit forcefully to gradually penetrate into the rock. This type of device usually faces three problems during field sampling: First, many outcrop rock samples have irregular shapes, making it difficult to find a suitable plane to fix the rock block, and the rock block is likely to be thrown out during the drilling process, posing a certain safety hazard to the operator; Second, the rock particles generated during the drilling process are likely to cause the drill bit to get stuck, and the drilled sample is stuck inside the drill bit and difficult to take out, and it is also difficult to obtain a complete plug sample, resulting in low work efficiency; Third, the hand-held battery drill is easily damaged in a complex field environment, especially when operating in a humid environment, its performance is unstable. How to efficiently obtain rock plug samples is a technical problem faced by current field on-site operations.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The embodiments of the present invention will be described below according to its overall structure.

[0031] Please refer to Figures 1 to 9 , in an embodiment of the present invention, a field portable rock plunger sample collection device and method includes a bottom plate 1. Support rods 2 are welded and fixed on both sides of the bottom plate 1. One end of the support rod 2 is welded and fixed with a positioning column 3 located above the bottom plate 1. A sampling mechanism 4 for sampling rocks is distributed on the top of the bottom plate 1 and the outside of the positioning column 3. The sampling mechanism 4 includes a reciprocating lead screw 401 rotatably connected to the bottom of the positioning column 3 through a bearing. A movable block 402 is sleeved on the outside of the reciprocating lead screw 401. A positioning frame 409 is arranged on the outside of the reciprocating lead screw 401. An installation seat 408 located below the movable block 402 is arranged inside the positioning frame 409. A sampling drill bit 410 is installed at the bottom of the installation seat 408;

[0032] Connection mechanisms 5 for connecting the sampling drill bit 410 are distributed on the bottom of the movable block 402 and the top of the installation seat 408.

[0033] In this embodiment: When using this device, the sampling drill bit 410 can be moved downward while rotating through the sampling mechanism 4, so as to reduce the labor intensity of the staff. When the sampling drill bit 410 moves to the lowest position, the sampling drill bit 410 can be made to lose rotation through the connection mechanism 5, so that it cannot rotate relative to the movable block 402 during the upward movement of the movable block 402, thereby preventing the core in the sampling drill bit 410 from falling due to the movement of the sampling drill bit 410, which provides convenience for the sampling of the device.

[0034] Please pay special attention to Figure 1 , 2, 3, 4, 5, 9, the sampling mechanism 4 further includes a mounting frame 426 disposed on the top of the movable block 402. A sleeve 406 is disposed inside the movable block 402 and outside the reciprocating lead screw 401. A first synchronous pulley 405 is disposed on the top of the sleeve 406. A synchronous belt 407 is disposed outside the first synchronous pulley 405. A sampling drill 403 is disposed on the top of the mounting frame 426. The output end of the sampling drill 403 is connected to a first rotating column 411 rotatably connected to the mounting frame 426 through a bearing. A limiting frame 412 penetrating to the outside of the mounting frame 426 is disposed inside the mounting frame 426. A first turntable 413 is rotatably connected to the inside of the limiting frame 412 through a bearing and is located below the sampling drill 403. A second rotating column 415 penetrating to the bottom of the movable block 402 is rotatably connected to the top of the movable block 402. A second synchronous pulley 416 is disposed on the top of the second rotating column 415. A second rectangular card slot 418 is formed inside the second rotating column 415. A third rectangular card slot 419 is disposed below the bottom of the second rotating column 415 and inside the second rectangular card slot 418. A first rectangular card block 414 penetrating to the inside of the second rectangular card slot 418 is disposed inside the first turntable 413. A first telescopic spring 420 is disposed inside the second rectangular card slot 418 at the bottom of the first rectangular card block 414. A first rectangular card slot 417 is disposed inside the first rotating column 411 and is fitted with the top of the first rectangular card block 414. A limiting component is disposed outside the positioning column 3 and above the limiting frame 412.

[0035] In this embodiment: After placing the device on the rock, the sampling drill 403 can be started. When the sampling drill 403 operates, it can drive the first rotating column 411 to rotate. When the first rotating column 411 rotates, it can drive the second synchronous pulley 416 and the second rotating column 415 to rotate through the first rectangular card block 414, so that the second synchronous pulley 416 drives the first synchronous pulley 405 to rotate through the synchronous belt 407, thereby driving the sleeve 406 to rotate by the first synchronous pulley 405, so that the sleeve 406 moves downward along the reciprocating lead screw 401, thereby driving the movable block 402 to move downward by the sleeve 406. During this process, the connection between the second rotating column 415 and the sampling bit 410 can be realized through the connecting mechanism 5, so that the sampling bit 410 rotates as the second rotating column 415 rotates, so that the sampling bit 410 moves downward during rotation, so that the sampling bit 410 can be drilled into the rock. This process is simple to operate and reduces the labor intensity of the staff, providing convenience for the sampling of rock cores.

[0036] Please refer to Figure 1 , 2, 3, 9. A through hole larger than the diameter of the reciprocating lead screw 401 is provided inside the first synchronous pulley 405, and a through hole that fits with the first rectangular block 414 is provided inside the second synchronous pulley 416. The first synchronous pulley 405 and the second synchronous pulley 416 are rotationally connected by a synchronous belt 407.

[0037] In this embodiment: By setting this structure, when the second synchronous pulley 416 rotates, it drives the first synchronous pulley 405 to rotate through the synchronous belt 407, so as to make the first synchronous pulley 405 drive the sleeve 406 to rotate.

[0038] Please refer specifically to Figure 1 , 3 , 4, 5. The limiting component includes a baffle 404 provided outside the positioning column 3 and above the limiting frame 412. A first torsion spring 424 is provided inside the baffle 404. A U-shaped limiting plate 421 is provided at the top of the baffle 404. One end of the baffle 404 is rotationally connected by a rotating shaft to a stopper 422 located below the U-shaped limiting plate 421. A second torsion spring 425 is connected to the outside of the rotating shaft where the stopper 422 is connected to the baffle 404 through a card slot. A first limiting block 423 located inside the U-shaped limiting plate 421 is welded and fixed to the top of the stopper 422.

[0039] In this embodiment: When the limiting frame 412 contacts the baffle 404 due to moving upward relative to the reciprocating screw rod 401, the baffle 404 will obstruct the movement of the limiting frame 412. At this time, the movable block 402 continues to move upward, while the limiting frame 412 cannot move due to the obstruction of the baffle 404. In this way, the sampling drill 403 can move upward relative to the limiting frame 412, so that the first rectangular block 414 is separated from the first rotating column 411 due to the upward movement of the sampling drill 403, thereby separating the first rectangular block 414 from the first rectangular slot 417. At this time, when the sampling drill 403 operates, it cannot drive the second synchronous wheel 416 to rotate, so that the movable block 402 loses the power to move. In this way, the single up-and-down reciprocating movement of the movable block 402 can be realized, which provides convenience for the staff to take out the core in the sampling drill bit 410. After that, the core in the sampling drill bit 410 can be removed. When using it again, the baffle 404 can be pushed, so that the stopper 422 contacts the limiting frame 412. As the baffle 404 rotates, the stopper 422 will rotate relative to the baffle 404 due to being limited by both sides of the limiting frame 412. During this process, the first torsion spring 424 and the second torsion spring 425 are wound up, so as to make the baffle 404 lose the shielding of the limiting frame 412. At this time, the limiting frame 412 will move upward relative to the mounting frame 426 under the action of the first telescopic spring 420. If the first rectangular slot 417 is aligned with the first rectangular block 414, at this time, the first rectangular block 414 will be buckled into the first rectangular slot 417 under the action of the first telescopic spring 420, so as to realize the connection between the first rotating column 411 and the second rotating column 415. If the first rectangular slot 417 is not aligned with the first rectangular block 414, at this time, the first rectangular block 414 will be attached to the bottom of the first rotating column 411 under the action of the first telescopic spring 420. As the sampling drill 403 drives the rotation of the first rotating column 411 to align the first rectangular slot 417 with the first rectangular block 414, the first rectangular block 414 will be buckled into the first rectangular slot 417 under the action of the first telescopic spring 420, which provides convenience for the rotation of the first rotating column 411 and the second rotating column 415.

[0040] Please refer specifically to Figure 1 , 5 , both ends of the first torsion spring 424 are respectively clamped to the inner side of the baffle 404 and the outer side of the positioning column 3 through slots. A groove that fits the first limiting block 423 is provided on one side of the baffle 404, and sliding grooves that fit both sides of the limiting frame 412 are provided on both sides of the mounting frame 426.

[0041] In this embodiment: By setting this structure, when the baffle 404 rotates relative to the positioning column 3, the first torsion spring 424 is wound up, so that the baffle 404 can be restored under the action of the first torsion spring 424 later.

[0042] Please refer specifically to Figure 1 , 6 , 7, 8, 9. The connecting mechanism 5 includes a support plate 501 disposed on the top of the bottom plate 1 and located on one side of the sampling drill bit 410. One side of the support plate 501 is rotatably connected to a rack 510 through a rotating shaft. One end of the support plate 501 is provided with a second limiting block 511 above the rack 510. A connecting frame 504 is provided at the bottom of the movable block 402. The bottom of the connecting frame 504 is rotatably connected to a one-way lead screw 505 through a bearing. One end of the one-way lead screw 505 is welded and fixed to a spur gear 509. A limiting slider 507 is sleeved on the outer side of the one-way lead screw 505. One side of the limiting slider 507 is welded and fixed to a trapezoidal block 506. A fourth rectangular card slot 503 is opened at the top of the mounting seat 408. One side of the trapezoidal block 506 is slidably connected to a moving frame 508 through a chute. The inner side of the moving frame 508 is rotatably connected to a second turntable 513 located below the second rotating column 415 through a bearing. A second rectangular card block 502 is welded and fixed to the inner side of the second turntable 513. A third rectangular card block 514 penetrating into the inner side of the third rectangular card slot 419 is provided inside the second rectangular card block 502. A second telescopic spring 515 is provided at the bottom of the third rectangular card block 514 inside the second rectangular card block 502. A third torsion spring 512 is provided on the outer side of the rotating shaft connecting the support plate 501 and the rack 510 and located inside the support plate 501.

[0043] In this embodiment: When the movable block 402 moves downward under the action of the sleeve 406, the spur gear 509 will contact the rack 510 above one side of the support plate 501. Since the rack 510 and the support plate 501 are in an inclined state, when the spur gear 509 moves downward, it can press the rack 510 at a higher position on one side of the support plate 501, so as to make the rack 510 rotate relative to the support plate 501. At this time, the second limiting block 511 above it cannot limit the rack 510, and at the same time, the third torsion spring 512 is wound up. In this way, the rack 510 at a higher position on one side of the support plate 501 can be pushed by the spur gear 509 to rotate to a position parallel to one side of the support plate 501. When the spur gear 509 separates from the rack 510 above one side of the support plate 501, the rack 510 at a higher position will be restored under the action of the third torsion spring 512. As the movable block 402 moves downward, the spur gear 509 will contact the rack 510 at a lower position on one side of the support plate 501, so as to make the rack 510 at a lower position turn downward. At this time, the second limiting block 511 below the rack 510 at a lower position will limit the rack 510. In this way, the rack 510 can be meshed with the spur gear 509. In this way, when the spur gear 509 moves downward relative to the support plate 501, it can rotate relative to the connecting frame 504, so as to make the one-way lead screw 505 rotate, and then make the limiting slider 507 drive the trapezoidal block 506 to move toward one side of the support plate 501. During this process, the moving frame 508 can move downward under the action of the inclined surface of the trapezoidal block 506. In this way, the third rectangular clamping block 514 can be separated from the third rectangular clamping groove 419, so as to make the sampling drill bit 410 lose the connection with the second rotating column 415. When the movable block 402 moves to the lowest position, the spur gear 509 separates from the rack 510 at a lower position on one side of the support plate 501, so that the rack 510 at a lower position is restored under the action of the third torsion spring 512. When the movable block 402 moves upward, the sampling drill bit 410 cannot rotate with the rotation of the second rotating column 415, so as to prevent the core in the sampling drill bit 410 from falling due to the movement of the sampling drill bit 410. At the same time, the spur gear 509 cannot be meshed with the rack 510 at a lower position on one side of the support plate 501. When the movable block 402 is about to move to the highest position, the spur gear 509 will be meshed with the rack 510 at a higher position on one side of the support plate 501, so as to make the spur gear 509 reverse, so as to make the moving frame 508 restored under the action of the reverse rotation of the one-way lead screw 505. Thus, the moving frame 508 drives the third rectangular clamping block 514 to move upward, so that when the movable block 402 moves to the highest position, the third rectangular clamping block 514 is inserted into the third rectangular clamping groove 419, so as to realize the connection between the sampling drill bit 410 and the second rotating column 415, which provides convenience for the subsequent use of the equipment. If the third rectangular clamping block 514 is not aligned with the third rectangular clamping groove 419 during the rising process,The rising distance of the third rectangular clamping block 514 will be converted into the distance that the third rectangular clamping block 514 retracts into the second rectangular clamping block 502. During this process, the second telescopic spring 515 contracts. Then, as the second rotating column 415 rotates and the third rectangular clamping groove 419 aligns with the third rectangular clamping block 514, the third rectangular clamping block 514 will be buckled into the third rectangular clamping groove 419 under the action of the second telescopic spring 515, facilitating the connection between the sampling drill bit 410 and the second rotating column 415.

[0044] Please refer specifically to Figure 9 , the bottom of the second rectangular clamping block 502 fits the size of the fourth rectangular clamping groove 503, the third rectangular clamping block 514 fits the size of the third rectangular clamping groove 419, a chute that fits the top of the moving frame 508 is provided on one side of the trapezoidal block 506, and a threaded hole that matches the outer side of the one-way lead screw 505 is provided inside the limit slider 507. One side of the rack 510 meshes with the outer side of the spur gear 509.

[0045] In this embodiment: By setting this structure, when the rack 510 meshes with the spur gear 509, the spur gear 509 rotates relative to the movable block 402 under the action of the movement of the movable block 402, thereby driving the one-way lead screw 505 to rotate. When the one-way lead screw 505 rotates, the limit slider 507 can move along the one-way lead screw 505, so that the trapezoidal block 506 moves. In this way, the moving frame 508 can drive the second rectangular clamping block 502 to move under the action of the inclined surface of the trapezoidal block 506.

[0046] Please refer specifically to Figure 1 , 7 , on one side of the support plate 501, two racks 510 are provided, and the rotatable directions of the two racks 510 are opposite. The diameter of the spur gear 509 is larger than the diameter of the one-way lead screw 505.

[0047] In this embodiment: By setting this structure, when the sampling drill 403 drives the first rectangular clamping block 414 to rotate through the first rotating column 411, the first rectangular clamping block 414 can drive the second synchronous pulley 416 to rotate, so that the second synchronous pulley 416 drives the sleeve 406 to rotate through the synchronous belt 407 and the first synchronous pulley 405, thereby enabling the movable block 402 to move along the reciprocating lead screw 401.

[0048] Please refer specifically to Figure 1 , 3 , a crescent pin that fits the outer side of the reciprocating lead screw 401 is provided inside the sleeve 406. The height of the chute on one side of the trapezoidal block 506 is greater than the height of the third rectangular clamping block 514, and the depth of the fourth rectangular clamping groove 503 is greater than the height of the third rectangular clamping block 514.

[0049] In this embodiment, when the sleeve 406 rotates relative to the movable block 402 by setting this structure, the sleeve 406 drives the movable block 402 to move reciprocally along the reciprocating lead screw 401. When the connecting mechanism 5 operates, the second rectangular block 502 can move within the fourth rectangular slot 503.

[0050] The following provides a method for collecting rock plunger samples in the field on-site in combination with the above-mentioned field portable rock plunger sample collection device and method, which specifically includes the following steps:

[0051] S1: When using the device, the sampling drill 403 can be started, and then the baffle 404 is pushed, so that the stopper 422 contacts the limit frame 412. As the baffle 404 rotates, the stopper 422 will rotate relative to the baffle 404 due to the limitation on both sides of the limit frame 412. During this process, the first torsion spring 424 and the second torsion spring 425 are wound up, so as to make the baffle 404 lose the shielding of the limit frame 412. At this time, the limit frame 412 will move upward relative to the mounting frame 426 under the action of the first telescopic spring 420;

[0052] S2: If the first rectangular slot 417 is aligned with the first rectangular block 414, at this time, the first rectangular block 414 will be buckled into the first rectangular slot 417 under the action of the first telescopic spring 420, so as to realize the connection between the first rotating column 411 and the second rotating column 415. If the first rectangular slot 417 is not aligned with the first rectangular block 414, at this time, the first rectangular block 414 will be attached to the bottom of the first rotating column 411 under the action of the first telescopic spring 420. As the sampling drill 403 drives the first rotating column 411 to rotate, the first rectangular slot 417 will be aligned with the first rectangular block 414, so that the first rectangular block 414 is buckled into the first rectangular slot 417 under the action of the first telescopic spring 420;

[0053] S3: Then, when the sampling drill 403 operates, it can drive the first rotating column 411 to rotate. When the first rotating column 411 rotates, it can drive the second synchronous wheel 416 and the second rotating column 415 to rotate through the first rectangular block 414, so that the second synchronous wheel 416 drives the first synchronous wheel 405 to rotate through the synchronous belt 407, so that the first synchronous wheel 405 drives the sleeve 406 to rotate, so that the sleeve 406 moves downward along the reciprocating lead screw 401, so that the sleeve 406 drives the movable block 402 to move downward. During this process, the connection between the second rotating column 415 and the sampling bit 410 can be realized through the connecting mechanism 5, so that the sampling bit 410 rotates as the second rotating column 415 rotates, so that the sampling bit 410 moves downward during rotation, so that the sampling bit 410 can be drilled into the rock;

[0054] S4: When the movable block 402 moves downward under the action of the sleeve 406, the sampling drill 403 drives the sampling drill bit 410 to rotate. At the same time, the spur gear 509 will contact the rack 510 located above one side of the support plate 501. Since the rack 510 and the support plate 501 are in an inclined state, when the spur gear 509 moves downward, it can press the rack 510 located at a higher position on one side of the support plate 501, so as to make the rack 510 rotate relative to the support plate 501. At this time, the second limiting block 511 located above it cannot limit the rack 510, and at the same time, the third torsion spring 512 is wound up. In this way, the rack 510 located at a higher position on one side of the support plate 501 can be pushed by the spur gear 509 to rotate to a position parallel to one side of the support plate 501. When the spur gear 509 separates from the rack 510 above one side of the support plate 501, the rack 510 located at a higher position will be restored under the action of the third torsion spring 512. As the movable block 402 moves downward, the spur gear 509 will contact the rack 510 located at a lower position on one side of the support plate 501, so as to make the rack 510 located at a lower position flip downward. At this time, the second limiting block 511 below the rack 510 located at a lower position will limit the rack 510. In this way, the rack 510 can be meshed with the spur gear 509. In this way, when the spur gear 509 moves downward relative to the support plate 501, it can rotate relative to the connecting frame 504, so as to make the one-way lead screw 505 rotate, thereby making the limiting slider 507 drive the trapezoidal block 506 to move toward one side of the support plate 501. During this process, the moving frame 508 can move downward under the action of the inclined surface of the trapezoidal block 506. In this way, the third rectangular clamping block 514 can be separated from the third rectangular clamping groove 419, so as to make the sampling drill bit 410 lose the connection of the second rotating column 415. When the movable block 402 moves to the lowest position, the spur gear 509 separates from the rack 510 located at a lower position on one side of the support plate 501, so that the rack 510 located at a lower position is restored under the action of the third torsion spring 512;

[0055] S5: When the movable block 402 moves upward, the sampling drill bit 410 cannot rotate along with the rotation of the second rotating column 415, so as to prevent the core in the sampling drill bit 410 from falling due to the movement of the sampling drill bit 410. At the same time, the spur gear 509 cannot mesh with the rack 510 at the lower position on one side of the support plate 501. When the movable block 402 is about to move to the highest position, the spur gear 509 will mesh with the rack 510 at the higher position on one side of the support plate 501, so as to reverse the spur gear 509, so that the moving frame 508 is restored under the action of the reverse rotation of the one-way lead screw 505, so that the moving frame 508 drives the third rectangular block 514 to move upward, so that when the movable block 402 moves to the highest position, the third rectangular block 514 is inserted into the third rectangular slot 419, so as to realize the connection between the sampling drill bit 410 and the second rotating column 415, which provides convenience for the subsequent use of the equipment;

[0056] S6: When the limit frame 412 contacts the baffle 404 due to moving upward relative to the reciprocating lead screw 401, the baffle 404 will hinder the movement of the limit frame 412. At this time, the movable block 402 continues to move upward, while the limit frame 412 cannot move due to the obstruction of the baffle 404. In this way, the sampling drill 403 can move upward relative to the limit frame 412. In this way, the first rectangular block 414 can be separated from the first rotating column 411 due to the upward movement of the sampling drill 403, so as to separate the first rectangular block 414 from the first rectangular slot 417. At this time, when the sampling drill 403 operates, it cannot drive the second synchronous pulley 416 to rotate, so that the movable block 402 loses the power to move. In this way, the single up-and-down reciprocating movement of the movable block 402 can be realized, which provides convenience for the staff to take out the core in the sampling drill bit 410. After that, the core in the sampling drill bit 410 can be taken out, which provides convenience for the subsequent detection of the core plug sample.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacement or change, and should be covered by the protection scope of the present invention.
