Description

Technical Field

[0001] This invention belongs to the field of geological exploration and drilling core testing technology, specifically relating to a core in-situ peeling and synchronous scanning testing device. Background Technology

[0002] This invention belongs to the field of geological exploration and drilling core testing technology, specifically relating to an in-situ core testing device. In oil and mineral extraction or geological exploration, obtaining underground core casings through drilling tools and detecting physical information such as morphology, fracture development, and geometric dimensions of the internal core column is a key means of analyzing stratigraphic structure. Traditional testing equipment and methods typically separate the fixing and clamping of the core casing, the unloading and stripping of the core column, and morphological measurement into independent offline steps: usually, a mechanical clamping mechanism and a propulsion unloading mechanism are used to completely push the core column out of the casing and place it in a core box, and then the stripped core column is transported to a specialized measuring instrument for surface data acquisition by handling or manual handling.

[0003] However, the existing offline detection mode of "unloading first, then transferring, and finally measuring" has many drawbacks. Because the peeling and morphological scanning are completely disconnected, the core column is exposed to air for a long time after being fully ejected and before measurement. Under the alternating influences of the external environment, it is highly susceptible to weathering, dehydration, or disintegration, resulting in measurement data that cannot accurately reflect the original physical morphology of the core underground. Traditional multiple transfer, placement, and retrieval operations can easily cause secondary fractures and surface physical damage to fragile or fractured core columns, severely compromising the integrity of the core structure. Furthermore, the multi-step offline operation leads to extremely low overall detection efficiency. During measurement, the relative movement trajectory between the detection sensor and the core is difficult to maintain absolute parallelism and stability. It is prone to spatial swaying or axial deviation during multi-axial movements or large strokes, and is easily obstructed by the physical structure of the equipment itself, thus failing to guarantee high accuracy and continuity of surface morphological data acquisition for the entire length of the core column. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a core in-situ desquamation and synchronous scanning detection device to solve the technical problems of offline detection in the prior art, which leads to long-term exposure of the core, easy weathering and disintegration, secondary damage caused by repeated handling and grasping, and low overall detection efficiency.

The C-shaped double inclined block is slidably disposed in a rectangular guide groove opened at the bottom of the lower clamping seat. A centering arc surface seat is fixed in a rectangular limiting groove at the bottom of the lower clamping seat. Lateral arc surface grippers that can slide horizontally are symmetrically arranged on the left and right sides of the centering arc surface seat. The gripper slide rods of the two lateral arc surface grippers slide through the guide transverse holes opened in the centering arc surface seat, and a split spring abuts between the two gripper slide rods. A wedge-shaped drive groove is opened on the top surface of the lateral arc surface gripper. The lower inclined surface of the C-shaped double inclined block slides through the wedge-shaped drive groove to drive the two lateral arc surface grippers to retract horizontally towards the center through inclined surface compression.

[0011] Optionally, the lower clamping seat has a mounting platform protruding from the center of its front end face. Three laser scanning sensors are provided and fixed side by side on the bottom surface of the mounting platform.

[0015] The beneficial effects of this invention are as follows: the device directly mounts a laser scanning sensor on the lower clamping seat, allowing it to perform real-time surface scanning of the exposed rock column as the clamping mechanism moves backward and axially removes the core casing. This in-situ integrated design of "peeling and detecting simultaneously" enables non-destructive measurement of the rock column the instant it is removed from the outer casing, greatly shortening the time the core is exposed to air and effectively preventing weathering, dehydration, or disintegration due to environmental changes. This ensures that the measurement data reflects the original underground morphology to the greatest extent possible. This method perfectly integrates peeling and morphological scanning in the same mechanical movement, eliminating the cumbersome offline steps of unloading, transporting, and measuring in traditional testing. This not only significantly improves testing efficiency but also completely eliminates the risk of further breakage and surface physical damage to the fragile rock column during secondary handling, placement, or manual handling, ensuring the integrity of the core. Because the sensor moves rigidly backward with the clamping seat, while the rock column is rigidly blocked and limited in place by the unloading pusher of the propulsion mechanism, this precise relative linear motion relationship ensures the absolute parallelism and stability of the sensor scanning trajectory and the rock column axis, thereby guaranteeing the high precision and continuity of data acquisition such as the surface geometry and apparent fracture development of the entire rock column.

[0018] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0019] Please refer to the figures. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0020] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0021] This invention provides a core in-situ desquamation and synchronous scanning detection device, comprising a base 1, with a leveling leg at each of the four corners of the base 1 for providing support and adjusting levelness. The leveling leg is specifically composed of an upper adjusting section 12 and a lower adjusting section 13 connected by an axial threaded joint. The top end of the upper adjusting section 12 is fixed to the bottom surface of the base 1, and the bottom end of the lower adjusting section 13 serves as a support end in contact with the ground. By rotating the lower adjusting section 13 or the upper adjusting section 12, the relative thread depth between them in the axial direction can be changed, thereby independently adjusting the height of the four corners of the base 1 relative to the ground, thus achieving precise leveling of the overall levelness of the top surface of the base 1.

[0022] On the top surface of the base 1, a gantry frame is horizontally fixed at both its front and rear ends along its length. The gantry frame has a symmetrical, U-shaped structure. Each gantry frame is specifically composed of two vertically distributed support columns 21 and a guide beam 22 horizontally fixed between the tops of the two support columns 21. The lower end of each support column 21 is firmly fixed to the edge of the top surface of the base 1, while its upper end is firmly connected to the bottom surfaces of both ends of the guide beam 22. On the vertical side of each guide beam 22 facing inwards, a beam guide groove 23 is formed along the entire transverse length of the guide beam 22. Inside the beam guide groove 23, a transverse trolley is horizontally slidable left and right along the length of the guide groove. The lateral trolley is specifically composed of a trolley frame 25 and multiple traveling rollers 26 disposed at the bottom of the trolley frame 25. The traveling rollers 26 are engaged inside the cavity of the crossbeam guide groove 23 and can roll smoothly along the cavity, thereby guiding the entire trolley frame 25 to slide laterally in a straight line within the crossbeam guide groove 23.

[0023] Inside the guide beam 22 of the gantry frame at the front end, a transverse drive screw 27 is horizontally mounted. A transverse drive motor 28 is fixedly installed at the outer transverse end of the guide beam 22 at the front end. The output shaft of the transverse drive motor 28 is coaxially and rigidly connected to the end of the transverse drive screw 27, thereby driving the transverse drive screw 27 to rotate around its own axis. A threaded through hole is provided on the trolley frame 25 of the transverse trolley at the front end. The aforementioned transverse drive screw 27 passes axially through the threaded through hole and forms a helical connection with the transverse trolley, so that the rotational motion of the transverse drive screw 27 can be converted into the transverse linear sliding of the front transverse trolley. Between the trolley frame 25 of the transverse trolley at the rear end and the trolley frame 25 of the transverse trolley at the front end, a longitudinal guide shaft 29 and a longitudinal transmission screw 210 are horizontally bridged and fixed. The longitudinal transmission screw 210 and the longitudinal guide shaft 29 are arranged parallel to each other in space. The front ends of both are fixed on the front transverse trolley and the rear ends are fixed on the rear transverse trolley. Thus, as the two transverse trolleys move laterally in sync, they move horizontally as a whole structure above the base 1.

[0024] A clamping mechanism for clamping and controlling the movement of the core tube is supported and suspended on the longitudinal guide shaft 29 and the longitudinal transmission screw 210. The clamping mechanism includes an upper mounting base 31 located on the upper part of the overall structure. Inside the upper mounting base 31, two parallel and through holes are formed along the front-to-back horizontal direction. A guide bushing 33 is tightly embedded in the inner wall of one of the upper through holes. The aforementioned longitudinal guide shaft 29 axially passes through this upper through hole with the guide bushing 33 and maintains a sliding connection with the inner surface of the guide bushing 33, thereby allowing the upper mounting base 31 to slide back and forth along the longitudinal guide shaft 29. Inside the other upper through hole, a longitudinal drive cylinder 34 is arranged in a manner that allows it to rotatably around its own axis. A longitudinal drive motor 35 is fixedly mounted on the upper end face of the upper mounting base 31. A transmission pinion 36 is coaxially fixedly mounted on the output end of the longitudinal drive motor 35. The teeth of the transmission pinion 36 form an external meshing connection with the gear structure on the outer circumferential direction of the longitudinal drive screw 34. The aforementioned longitudinal drive screw 210 axially passes through the upper through hole of the longitudinal drive screw 34 and forms a screw-nut transmission connection with the internal thread of the longitudinal drive screw 34. When the longitudinal drive motor 35 drives the transmission pinion 36 to rotate and drives the longitudinal drive screw 34 to rotate, it drives the entire upper mounting base 31 to move back and forth linearly along the longitudinal drive screw 210.

[0025] A lower clamping seat 37 is disposed directly below the upper mounting base 31. Four vertical guide rods 38 are fixedly mounted vertically upwards at the four corners of the top surface of the lower clamping seat 37. These four vertical guide rods 38 extend vertically upwards and slide through four vertical guide holes opened in the upper mounting base 31. Through the precise sliding fit between the vertical guide rods 38 and the guide holes, the relative movement between the lower clamping seat 37 and the upper mounting base 31 is restricted, allowing it to move vertically only in a linear vertical direction. A lifting hydraulic cylinder 39 is fixedly installed inside the upper mounting base 31. The piston rod of the lifting hydraulic cylinder 39 extends vertically downwards through the upper mounting base 31 as the lower output end and is rigidly fixedly connected to the top surface of the lower clamping seat 37. The lower clamping seat 37 is driven to move vertically up and down relative to the upper mounting base 31 by the input and output of hydraulic oil. A mounting platform 322 extends horizontally forward from the center of the front end face of the lower clamping seat 37. Three laser scanning sensors 323 are horizontally fixedly mounted on the bottom surface of the mounting platform 322, arranged side by side from left to right. The main scanning probe of the laser scanning sensor 323 located in the center is vertically oriented downwards, while the main scanning probes of the other two laser scanning sensors 323 symmetrically distributed on the left and right sides of the central laser scanning sensor 323 are respectively inclined downwards, so that the scanning axes of the three laser scanning sensors 323 are arranged in an inverted V-shape radial pattern in space.

[0026] A clamping electric cylinder 310 with its output end facing directly downwards is disposed within the internal cavity of the lower clamping seat 37. The body of the clamping electric cylinder 310 is fixed to the internal top wall of the lower clamping seat 37, and its linearly extendable lower output end is vertically and fixedly connected to a C-shaped double-sloping block 311 with its opening facing directly downwards. The C-shaped double-sloping block 311 has two downwardly extending inclined sections that are symmetrically distributed horizontally and spaced apart. The inner opposing surfaces of these two downwardly extending inclined sections are machined into inwardly inclined extrusion slopes, so that the entire lower extension of the C-shaped double-sloping block 311 presents a symmetrical V-shaped shape that is narrower at the top and wider at the bottom. In the central region of the bottom surface of the lower clamping seat 37, a rectangular limiting groove 314 is horizontally recessed upwards. In the center of the inner top surface of the rectangular limiting groove 314, a rectangular guide groove 315 is further vertically recessed upwards. The aforementioned C-shaped double-sloping block 311 is embedded in the rectangular guide groove 315 in a vertically sliding manner. A centering arc-shaped seat 316 is horizontally fixed at the geometric center of the rectangular limiting groove 314. The arc-shaped concave surface of the centering arc-shaped seat 316 faces directly downwards, and the radius of curvature of this concave surface is adapted to the outer diameter of the core outer tube 5 to be clamped by the device. A lateral arc-shaped gripper 317 is symmetrically arranged on the left and right sides of the centering arc-shaped seat 316, and is horizontally sliding. Inwardly extending gripper slide rods 318 are horizontally fixedly connected to the sides of the two lateral arc-shaped grippers 317 facing the centering arc-shaped seat 316. A guide transverse hole is horizontally penetrated through the solid interior of the centering arc-shaped seat 316. The gripper slides 318 of the two lateral arc-shaped grippers 317 slide into the guide transverse holes from the left and right sides of the centering arc-shaped seat 316, respectively. Inside the guide transverse hole between the two gripper slides 318, a compressed split spring 320 is fitted and supported. The two ends of the split spring 320 abut against the opposite ends of the two gripper slides 318, thus maintaining an elastic tendency to push the two lateral arc-shaped grippers 317 outwards. On the top surface of each lateral arc-shaped gripper 317, a wedge-shaped drive groove 321 is vertically formed downwards, matching the shape of the lower inclined portion of the aforementioned C-shaped double-inclined block 311. The two downwardly extending inclined surfaces of the aforementioned C-shaped double inclined block 311 slide from above into the wedge-shaped drive grooves 321 of the two lateral arc-shaped grippers 317. Through the sliding contact between the inner pressing inclined surface of the C-shaped double inclined block 311 and the outer inclined surface of the wedge-shaped drive groove 321, the vertical downward thrust of the clamping electric cylinder 310 is converted into a lateral clamping force that drives the two lateral arc-shaped grippers 317 to retract horizontally toward the center to clamp the core outer tube 5.When the two lateral arc-shaped grippers 317 retract inward and firmly clamp the core outer tube 5, the inner arc surfaces of the two lateral arc-shaped grippers 317 are tightly attached to the outer walls of both sides of the core outer tube 5, while the arc concave surface of the aforementioned centering arc-shaped seat 316 is attached to the top outer wall of the core outer tube 5. When viewed from the front of the entire device, the contact surfaces of the two lateral arc-shaped grippers 317 are firmly attached to the upper and lower outer peripheries of the side of the core outer tube 5.

[0027] On the top surface of the base 1, in the area between the two gantry frames, a rectangular core storage box 14 is horizontally fixed. On the top surface of the core storage box 14, several downwardly recessed core receiving slots are arranged side-by-side in a transverse direction. The geometric center line of each core receiving slot extends completely parallel to the longitudinal movement direction of the aforementioned clamping mechanism. At the longitudinal front end of each core receiving slot, a front stop plane with a vertical surface is fixedly installed, while the longitudinal rear end of each core receiving slot is completely open without any obstructions or blocking components, facilitating the axial withdrawal of the fittings and the stripping and retention of the core column.

[0028] On the front end face of the trolley frame 25 of the lateral trolley located at the rear end, a cantilever-shaped tail support 44 is horizontally fixedly mounted. Directly below the tail support 44, a suspended bearing 41 that can move up and down is suspended in mid-air. At the four corners of the top surface of the suspended bearing 41, four lifting guide shafts 42 are vertically fixedly mounted. These four lifting guide shafts 42 slide upwards and pass into four lifting guide holes opened inside the tail support 44. At the center of the top upper surface of the suspended bearing 41, an adjusting screw 43 extending vertically upwards is also fixedly mounted. On the body structure of the tail support 44, a vertical through hole is opened vertically. Inside the vertical through hole, a lifting drive screw 45 is installed in a freely rotatable manner. The aforementioned adjusting screw 43 passes downwards through the vertical through hole where the lifting drive screw 45 is located, and forms a screw-nut pair with the internal thread of the lifting drive screw 45. A height adjustment motor 46 is fixedly installed on the outer wall of the tail support 44. A height transmission gear 47 is horizontally arranged at the end of the output shaft of the height adjustment motor 46. The height transmission gear 47 is connected to the outer peripheral gear teeth of the lifting drive screw 45. The height adjustment motor 46 drives the lifting drive screw 45 to rotate in the vertical through hole, thereby using the threaded pair to drive the adjusting screw 43 together with the suspension bearing 41 below to adjust the height in the vertical direction along the lifting guide shaft 42.

[0029] Inside the suspension support 41, a through hole is formed horizontally in the front-to-back direction. A propulsion drive cylinder 49 is rotatably nested inside the through hole. A propulsion motor 410 is fixedly mounted on the left outer wall of the suspension support 41. A propulsion drive gear 411 is fixedly mounted on the output shaft of the propulsion motor 410. The teeth of the propulsion drive gear 411 mesh with the outer peripheral teeth of the propulsion drive cylinder 49 to establish a transmission engagement. The detection device also includes a propulsion main screw 412 placed horizontally in the front-to-back direction. The propulsion main screw 412 passes axially through the aforementioned through hole and forms a screw-nut transmission pair with the internal thread of the propulsion drive cylinder 49. A cylindrical front guide shaft 413 extends forward axially from the front end of the propulsion main screw 412. A disc-shaped travel limit head 414 is fixed at the foremost end of the front guide shaft 413. On the outer circumferential surface of the front guide optical shaft 413, a tubular sliding buffer sleeve 415 is fitted in a manner that allows it to slide freely back and forth along the longitudinal movement direction of the clamping mechanism. Inside the hollow cavity of the sliding buffer sleeve 415, between the inner stepped surface of the sliding buffer sleeve 415 and the rear end face of the stroke limiting head 414, a pre-tightened buffer compression spring 416 is supported and fitted. An elastic floating pressure block 417 is rigidly fixedly connected to the outer edge of the front end of the sliding buffer sleeve 415. The bottom side of the elastic floating pressure block 417 is machined into a downwardly concave centering surface, and two rows of freely rotatable anti-friction balls 419 are arranged symmetrically on this centering concave surface. The elastic floating pressure block 417 presses down on the core column located in the aforementioned core receiving groove from above through the anti-friction balls 419. At the rear end of the main feed screw 412, a block-shaped transmission reversing block 420 is rigidly fixedly installed. A longitudinal push rod 421 extending horizontally forward is horizontally fixedly connected to the lower front side of the transmission reversing block 420. The longitudinal push rod 421 and the main push screw 412 are spatially strictly parallel. The longitudinal push rod 421 extends horizontally forward and passes through the suspension bearing seat 41, and a discharge pusher 422 is threadedly connected to its foremost end. The discharge pusher 422 is generally disc-shaped, and the outer diameter of the disc is machined to be smaller than the inner diameter of the aforementioned core outer tube 5, so that the discharge pusher 422 can extend into the core outer tube 5 without obstruction. In terms of spatial axial position, the foremost position of the aforementioned freely extending and elastic floating pressure block 417 is further forward than the front end face of the discharge pusher 422. Between the elastic floating pressure block 417 and the transmission reversing block 420, an anti-rotation auxiliary guide rod 423 is also horizontally fixedly connected to prevent the propulsion structure from rotating.The anti-rotation auxiliary guide rod 423 extends horizontally backward and slides through the suspension bearing seat 41.

[0030] In the initial stage of the entire device's operation, the first step is to perform leveling on the four corners of the base 1. This is done by adjusting the leveling legs located at the four corners of the base 1's bottom surface. Specifically, rotating the lower adjusting section 13 of the leveling leg changes the relative screw depth between the lower and upper adjusting sections 12, thus allowing for independent adjustment of the height of each of the four corners of the base 1. Once the top surface of the base 1 is completely level, the leveling operation is complete, providing a high-precision horizontal reference for the subsequent precise linear displacement of each component in space.

[0031] After the overall level of the base 1 is adjusted, the device performs a lateral alignment operation. The control system starts the lateral drive motor 28, which is fixed to the outer end of the guide beam 22 of the front gantry frame. The lateral drive motor 28 drives the lateral drive screw 27, which is coaxially connected to its output shaft, to rotate around its own axis. The lateral drive screw 27 drives the front lateral trolley through a screw connection. Since the front lateral trolley and the rear lateral trolley are rigidly and horizontally connected and fixed by the longitudinal guide shaft 29 and the longitudinal transmission screw 210, when the front lateral trolley moves laterally, it synchronously pulls the rear lateral trolley. The traveling rollers 26 of the front and rear transverse trolleys roll smoothly in the crossbeam guide grooves 23 opened on the sides of the front and rear guide crossbeams 22, and carry the trolley frame 25 to slide laterally linearly. This causes the clamping mechanism suspended on the longitudinal guide shaft 29 and the longitudinal transmission screw 210, as well as the tail support seat 44 and suspension bearing seat 41 fixed at the front end of the rear transverse trolley, and other propulsion components to move laterally horizontally as a whole until the longitudinal centerline of the entire moving component is completely aligned with the extension direction of the target core receiving groove arranged on the core storage box 14 fixed on the top surface of the base 1.

[0032] After lateral alignment, the device performs the downward movement of the clamping mechanism and clamping of the outer core tube 5. The control system first activates the lifting hydraulic cylinder 39 fixed inside the upper mounting base 31 of the clamping mechanism. The lower output end of the lifting hydraulic cylinder 39 outputs vertically downwards, pushing the lower clamping seat 37 downwards relative to the upper mounting base 31. During this process, the four vertical guide rods 38 fixed at the four corners of the top of the lower clamping seat 37 slide upwards through the upper mounting base 31, precisely guiding the lower clamping seat 37 to move only linearly downwards in the vertical direction. The lower clamping seat 37 moves downwards until the concave surface of the centering arc surface seat 316 fixed in the middle of the rectangular limiting groove 314 abuts against the top side of the outer core tube 5 to be inspected. Subsequently, the control system activates the clamping electric cylinder 310 located inside the lower clamping seat 37. The lower output end of the clamping electric cylinder 310 extends vertically downwards, pushing the C-shaped double-inclined block 311 to slide vertically downwards within the rectangular guide groove 315. The two downwardly extending inclined surfaces of the C-shaped double-inclined block 311 slide into the wedge-shaped drive grooves 321 at the top of the two lateral arc-shaped grippers 317. The lateral force generated by the inner pressing inclined surfaces overcomes the elastic tension of the split springs 320 supporting the two gripper slide rods 318, driving the two lateral arc-shaped grippers 317 to retract towards the center. The gripper slide rods 318 of the two lateral arc-shaped grippers 317 slide from the left and right into the guide transverse holes that extend through the centering arc-shaped seat 316. The two lateral arc-shaped clamps 317 retract inward and firmly clamp the outer core tube 5, so that its two sides are attached to the inner arc surface of the lateral arc-shaped clamps 317. The centering arc-shaped seat 316 is attached to the top side of the outer core tube 5. From the front, the lateral arc-shaped clamps 317 are firmly attached to the upper and lower sides of the outer core tube 5, completing the centering and clamping of the outer core tube 5 around its perimeter and locking of its axis.

[0033] After the outer core tube 5 is centered and clamped around its perimeter, the device performs a longitudinal pushing and positioning operation. The control system activates the longitudinal drive motor 35 fixed to the upper end of the upper mounting base 31 of the clamping mechanism. The longitudinal drive motor 35 drives the transmission pinion 36 at its end to rotate. The transmission pinion 36 engages axially with the outer teeth of the longitudinal drive screw 34, which is rotatably located in one of the upper through holes, thereby driving the longitudinal drive screw 34 to rotate around its own axis. Since the longitudinal drive screw 210 axially passes through the upper through hole where the longitudinal drive screw 34 is located and is threadedly connected to the longitudinal drive screw 34, and the longitudinal guide shaft 29 axially passes through the other upper through hole where the guide bushing 33 is located and is slidably connected to the guide bushing 33, the rotation of the longitudinal drive screw 34 drives the entire upper mounting base 31 to move forward linearly along the longitudinal drive screw 210. The upper mounting base 31 is rigidly and laterally connected to the vertical guide rod 38 and the lifting hydraulic cylinder 39, which drives the lower clamping base 37 to move forward synchronously, thereby causing the clamping mechanism to clamp the core outer tube 5 and move forward as a whole until the front end of the core outer tube 5 is completely abutted against the front stop plane at the front end of the target core receiving groove, so that the core outer tube 5 is firmly limited by the front stop plane in the longitudinal axial direction.

[0034] Subsequently, the device performs preliminary adjustment and clamping operations on the propulsion mechanism. The control system first starts the propulsion motor 410 fixed on the left side of the suspension support 41. The propulsion motor 410 rotates, and the propulsion transmission gear 411 at its end drives the propulsion transmission screw 49, which is rotatably installed in the front and rear through holes, to rotate. Since the propulsion main screw 412 is threadedly connected to the propulsion transmission screw 49, the rotation of the propulsion transmission screw 49 drives the propulsion main screw 412 to extend forward in the front and rear horizontal direction. As the propulsion main screw 412 moves forward, it drives the transmission reversing block 420 fixed at its rear end, the longitudinal propulsion rod 421 fixed at the lower front side of the transmission reversing block 420, and the unloading push head 422 fixed at the front end of the longitudinal propulsion rod 421 to move forward horizontally in sync. During this period, the anti-rotation auxiliary guide rod 423 fixed between the elastic floating pressure block 417 and the transmission reversing block 420 slides through the suspension support 41 to prevent the propulsion main screw 412 from rotating. The propulsion motor 410 drives the unloading pusher 422 forward to a predetermined position, so that the unloading pusher 422 accurately approaches and aligns with the unobstructed rear end of the core outer tube 5, but controls it to maintain a small axial distance without actually contacting the core outer tube 5. Immediately afterwards, the control system activates the height adjustment motor 46 fixed on the outside of the tail support 44. The height adjustment motor 46 drives the lifting drive screw 45, which is set in the vertical through hole, to rotate through the height transmission gear 47. The rotation of the lifting drive screw 45 drives the adjusting screw shaft 43 to move vertically downward, thereby causing the suspension bearing 41, together with the four lifting guide shafts 42 fixed at the four corners of the suspension bearing 41 and extending upward, to slide vertically downward within the tail support 44. The suspension bearing 41, along with the propulsion mechanism, continues to move smoothly downwards. Because the axial position of the elastic floating pressure block 417 is designed to be ahead of the unloading pusher 422, during the downward translation of the entire mechanism, the elastic floating pressure block 417, which is slidably mounted on the front guide shaft 413 and fixed to the end of the sliding buffer sleeve 415, first contacts the core outer tube 5. The suspension bearing 41 continues to move downwards a small distance, causing the centering concave structure of the bottom side of the elastic floating pressure block 417 and the symmetrically arranged two rows of anti-friction ball bearings 419 to adhere and firmly press against the core outer tube 5 from above, achieving flexible, elastic, and stable pressure on the top of the core outer tube 5.

[0035] After the elastic floating pressure block 417 stably presses down on the core outer tube 5, the control system restarts or continues to start the propulsion motor 410, driving the propulsion transmission gear 411 and the propulsion transmission screw 49 to rotate, causing the propulsion main screw 412 to extend further forward horizontally. The propulsion main screw 412 drives the longitudinal propulsion rod 421 and the unloading pusher 422 at the front end to continue moving forward horizontally through the transmission reversing block 420 at the rear end. Since the unloading pusher 422 has a disc structure with a diameter smaller than the inner diameter of the core outer tube 5, it smoothly extends into the internal cavity of the core outer tube 5 from the rear end without obstruction. The unloading pusher 422 continues to move forward inside the core outer tube 5 until its front end face completely and tightly abuts against the rear end face of the core column located inside the core outer tube 5. During this process, since the sliding buffer sleeve 415 is slidably mounted on the front guide shaft 413 along the moving direction of the clamping mechanism, as the main screw 412 continues to move forward, the front guide shaft 413 slides forward inside the sliding buffer sleeve 415, while the elastic floating pressure block 417 remains pressed against the surface of the core outer tube 5 without interference under the action of the anti-friction ball 419. Subsequently, the propulsion motor 410 stops rotating and locks itself, and the propulsion transmission screw 49 rigidly locks the main screw 412, the transmission reversing block 420, the longitudinal propulsion rod 421, and the unloading pusher 422 in the axial direction, preventing them from retreating, thereby establishing an absolutely firm axial blocking boundary at the rear end of the core column.

[0036] Next, the entire device enters the core stage of shell removal and in-situ measurement. The control system controls the longitudinal drive motor 35 of the clamping mechanism to start and reverse. The longitudinal drive motor 35 rotates in the opposite direction, driving the transmission pinion 36 at the end to rotate in the opposite direction. The transmission pinion 36 meshes with the outer axial periphery of the longitudinal drive screw 34, driving the longitudinal drive screw 34 to rotate in the opposite direction. Since the longitudinal drive screw 210 is kept axially locked by the transverse trolley, the rotation of the longitudinal drive screw 34 drives the entire upper mounting base 31 to move backward in a straight line along the longitudinal drive screw 210 and the longitudinal guide shaft 29. At this time, the lower clamping base 37, fixed below the upper mounting base 31, moves backward synchronously with the upper mounting base 31 through the vertical guide rod 38 and the lifting hydraulic cylinder 39. Since the lateral arc-shaped grippers 317 and the centering arc-shaped seat 316 inside the lower clamping base 37 still maintain a strong clamping state on the core outer tube 5, the core outer tube 5 is pulled out backward along with the entire clamping mechanism. However, the core column located inside the outer core tube 5 is unable to move backward axially and remains stationary due to the strong restriction imposed by the unloading pusher 422, which is axially locked and stationary at its rear end. As the outer core tube 5 is continuously pulled backward axially by the entire clamping mechanism, the core column gradually peels off from the front end of the outer core tube 5 and remains stably and neatly in place within the pre-aligned core receiving groove due to the unobstructed rear end of the core receiving groove. During this relative extraction process, the lateral arc-shaped grippers 317 and the centering arc-shaped seat 316 of the clamping mechanism, together with the elastic floating pressure block 417, jointly move and guide the outer core tube 5 in multiple directions, ensuring extreme stability of the outer tube's backward axis and preventing the outer tube from jumping. At the same time, the three laser scanning sensors 323 fixed on the lower side of the mounting platform 322 protruding from the front end of the lower clamping seat 37 move backward synchronously with the lower clamping seat 37 and start working. The three laser scanning sensors 323 perform multi-angle and all-round synchronous surface scanning measurement on the core column that is continuously peeled off and exposed in the core receiving groove, accurately obtaining the in-situ morphological physical information of the core column.

[0037] As the clamping mechanism continues to move backward while holding the core outer tube 5, the lower clamping seat 37 gradually moves backward until it comes into contact with the elastic floating pressure block 417. Since the initial position of the elastic floating pressure block 417 in the spatial axial direction is ahead of the unloading pusher 422, after the clamping mechanism moves backward and comes into contact with the elastic floating pressure block 417, as the clamping mechanism moves further backward, the rear solid structure of the lower clamping seat 37 overcomes the resistance and begins to apply a backward thrust to the elastic floating pressure block 417. This backward thrust overcomes the elastic force of the buffer compression spring 416, forcing the sliding buffer sleeve 415 to slide axially relative to the front guide optical shaft 413 and the stroke limit head 414, thereby causing the buffer compression spring 416, which is supported inside the sliding buffer sleeve 415 and between the stroke limit head 414, to undergo elastic compression. In this state, the clamping mechanism pushes the elastic floating block 417 and the sliding buffer sleeve 415 backward along the front guide optical axis 413, which remains stationary and locked, following the clamping mechanism. The clamping mechanism drives the elastic floating block 417 to move backward synchronously, avoiding physical obstruction of the scanning and measurement paths of the three laser scanning sensors 323 on the mounting platform 322, ensuring unobstructed sensor visibility. The clamping mechanism and the elastic floating block 417 continue to move backward synchronously until the outer core tube 5 is completely extracted from the core column, thus achieving complete physical separation of the outer core tube 5 from the core column. At this point, the entire core column remains intact in the core receiving groove, and the three laser scanning sensors 323 have simultaneously completed scanning the entire surface of the core column, successfully completing the data acquisition and measurement work.

[0038] After all the measurement work is completed, the device lifts the components to facilitate material removal. The control system simultaneously starts the lifting hydraulic cylinder 39 of the clamping mechanism and the height adjustment motor 46 of the propulsion mechanism. The lower output end of the lifting hydraulic cylinder 39 retracts vertically upward, pulling the lower clamping seat 37, mounting platform 322, laser scanning sensor 323, centering arc surface seat 316, and two lateral arc surface grippers 317 vertically upward along the four vertical guide rods 38. At the same time, the height adjustment motor 46 drives the lifting drive cylinder 45, which is set in the vertical through hole, to rotate in the opposite direction through the height transmission gear 47. Utilizing the threaded engagement with the adjusting screw 43, it drives the adjusting screw 43, together with the suspension bearing seat 41, the four lifting guide shafts 42 fixed at the four corners of the suspension bearing seat 41 and extending upward, as well as the entire propulsion main screw 412, transmission reversing block 420, longitudinal propulsion rod 421, unloading push head 422, and elastic floating pressure block 417, to be vertically lifted. By simultaneously moving vertically upwards through the clamping mechanism and the propulsion mechanism, the core outer tube 5 clamped on the lower clamping seat 37 is significantly raised in vertical height, making it significantly higher than the core column that remains flat in the core receiving groove. This creates a completely open and interference-free extraction channel for the core column, greatly facilitating the safe removal of the empty core outer tube 5 and the intact core column from the device by operators or external extraction robots.

[0039] After the material is collected, all components and actuators of the entire device undergo reset and cycle preparation.

[0040] In this invention, the leveling legs at the bottom of the device, connected by threaded upper and lower adjustment sections 12 and 13, can independently adjust the height of the four corners to accurately compensate for ground unevenness, thus establishing a high-precision horizontal measurement benchmark for the equipment. The synchronous linkage design of the double gantry frame and the front and rear transverse trolleys, driven by the transverse drive motor 28 and the lead screw, ensures extremely high stability and alignment accuracy of the clamping and propulsion mechanisms when aligning with the target core receiving slot during transverse switching positions. The clamping mechanism is vertically guided by the lifting hydraulic cylinder 39 and uses the clamping electric cylinder 310 to drive the C-shaped double inclined block 311, forcing the lateral arc-shaped grippers 317 to retract inward. This achieves multi-point self-centering and balanced clamping of the top and sides of the core outer tube 5, locking the working axis and preventing local deformation of the outer tube. Furthermore, the propulsion mechanism, through an elastic floating pressure block 417 equipped with a buffer compression spring 416 and anti-friction balls 419, flexibly presses the tube from above during unloading. Combined with an axially locked unloading pusher 422 and a rearward-moving clamping mechanism, this achieves stable in-situ peeling and detachment of the core column, effectively preventing core jumping or fracturing and perfectly preserving its original physical morphology. Simultaneously, three laser scanning sensors 323 arranged in an inverted V-shape move backward synchronously with the lower clamping seat 37, enabling multi-view, all-around in-situ non-destructive scanning. Later, the clamping mechanism automatically pushes the elastic floating pressure block 417 backward, creating a sliding and retraction mechanism, eliminating physical obstructions along the measurement path. This ensures complete and seamless acquisition of the surface morphology data of the entire core column, resulting in a high degree of automation and significant advantages for in-situ integrated detection.
