Description

Technical Field

[0001] The present application belongs to the technical field of rock cutting equipment, and specifically relates to a core cutting equipment and a cutting method. Background Art

[0002] In the process of geological exploration and mineral development, the analysis of cores is crucial. The cores of the target strata drilled from underground are cylindrical in structure, and it is often necessary to cut the cylindrical cores first, and then conduct different analysis tests on the cut cores according to research needs.

[0003] The quality of core cutting will affect the subsequent analysis and test results, especially for cores obtained from deep drilling, which are very precious and have high requirements for accurate core cutting. However, under existing technical conditions, core cutting is mainly done by pushing the core under the cutter with a hand-held push rod. It is difficult to achieve high-precision alignment by manually pushing the core to align the cutter, which greatly reduces the cutting accuracy and affects the subsequent analysis and testing of the core. In addition, in the past, after the core cutting was completed, the cut core parts could not be effectively stored and sorted, and were often randomly stacked, which was not only inconvenient for storage, but also easy to cause damage or loss of the core.

[0051] A specific embodiment of the present invention, as Figures 1 to 4 As shown, a core cutting device is disclosed, comprising: a cutting mechanism 10, having a cutting knife 11, which moves along the cutting center line 20 direction to cut the core after being aligned with the core axis; a first slide rail mechanism 31, which is driven and connected to a first loading seat 311, and the first loading seat 311 has first stoppers 312 at both ends; a second slide rail mechanism 32, which is spaced apart from the first slide rail mechanism 31, and the two are symmetrically arranged with respect to the cutting center line 20, and is driven and connected to a second loading seat 321, and the second loading seat 321 has second stoppers 322 at both ends. When the core is placed on the first loading seat 311 and the second loading seat 321, the first loading seat 311 and the second loading seat 321 respectively abut against two of the core side walls In relative position, the axis of the core is colinear with the cutting centerline 20, the first stopper 312 is located on one side of the cutting centerline 20, and the second stopper 322 is located on the other side of the cutting centerline 20; the cutting section elastic mechanism 40 is arranged between the cutting mechanism 10 and the starting position when the core is cut, and is used to apply a fixing force to the side wall of the core; the tail end elastic mechanism 41 is arranged between the cutting mechanism 10 and the end point of the transfer after the core cutting is completed, and is used to apply a fixing force to the side wall of the core; the transition piece 50 is arranged on the cutting centerline 20 between the cutting section elastic mechanism 40 and the tail end elastic mechanism 41; the storage box 60 is arranged corresponding to the first slide rail mechanism 31 and the second slide rail mechanism 32, and is tightly attached to the end of the tail end elastic mechanism 41.

[0052] In this embodiment, after the cutting knife 11 is aligned with the core axis through the provided cutting mechanism 10, it moves along the cutting center line 20 to cut the core. Specifically, the first loading seat 311 and the second loading seat 321 on the first slide rail mechanism 31 and the second slide rail mechanism 32 are moved to the loading position, and the first loading seat 311 and the second loading seat 321 are arranged side by side at this time, and there is a gap in the middle. The core is placed on the first loading seat 311 and the second loading seat 321. At this time, the axis of the core is in line with the cutting center line 20, and the side wall of the core is supported by the first loading seat 311 and the second loading seat 321 from opposite sides to ensure that the core is placed stably. At the same time, the cutting section elastic mechanism 40 applies a fixing force to the side wall of the core to further fix the core. The first material loading seat 311 and the second material loading seat 321 move at the same time, and the first material blocking member 312 and the second material blocking member 322 push the core in the blocking space formed on their respective tracks 71, so that the core is close to the cutting mechanism 10, and the cutting knife 11 cuts the core. After cutting, a cutting seam is generated. At the same time, the first material loading seat 311 and the second material loading seat 321 move at the same time, so that the transition piece 50 is inserted into the cutting seam, ensuring that the core after cutting remains stable under the action of the cutting section elastic mechanism 40 and will not scatter. The setting of the transition piece 50 prevents the core from being squeezed by the elastic force and causing a strong collision. Through the transition piece 50, one end of the core continues to move, and through the tail end elastic mechanism 41, one end of the core passes through the transition piece 50 and is gathered by the tail end elastic mechanism 41 until the core is within the range of the tail end elastic mechanism 41. At this time, the first material loading seat 311 and the second material loading seat 321 drive the separated cores to move at the same time, ensuring that they will not scatter due to different speeds until the core is pushed into the storage box 60. After the cutting knife 11 is aligned with the core axis, it moves along the cutting center line 20 to cut, and cooperates with the first slide rail mechanism 31 and the second slide rail mechanism 32 to accurately position the core, so that the core axis is in line with the cutting center line 20, ensuring the accuracy and precision of the cutting. This precise cutting provides high-quality samples for subsequent analysis and research on the core, reducing errors caused by cutting deviations.

[0053] The cutting section elastic mechanism 40 and the tail end elastic mechanism 41 have the same structure.

[0054] Each mechanism provided in this embodiment is arranged on the cutting table.

[0055] In some embodiments, the transition piece 50 includes a plurality of transition rods arranged at intervals, and the plurality of transition rods are arranged one by one along the moving direction of the core on the cutting centerline 20. A rubber roller 501 is rotatably connected to the transition rod. The diameter of the rubber roller 501 decreases from the first one close to the cutting mechanism 10 to the end point where the core is transferred after the cutting is completed. The diameter of the first rubber roller 501 is the same as the cutting seam after the cutting mechanism 10 cuts the core.

[0056] In some embodiments, a plurality of transition bars arranged at intervals are arranged one by one along the moving direction of the core on the cutting center line 20, and this arrangement provides continuous support and guidance for the core. A rubber roller 501 is rotatably connected to each transition bar, so that the core can contact the rubber roller 501 during the movement, rather than directly contacting the rigid transition bar, thereby reducing the possibility of friction and collision.

[0057] In some embodiments, the diameter of the rubber roller 501 decreases from the first one close to the cutting mechanism 10 to the end point where the core is transferred after the core is cut. This design is based on the actual needs of the core during movement. The diameter of the first rubber roller 501 is the same as the cutting seam after the cutting mechanism 10 cuts the core, and can be inserted into the cutting seam to provide initial support and guidance for the core. As the core moves, the subsequent rubber rollers 501 with smaller diameters play a role in turn, gradually guiding the core to move toward the end point.

[0058] After the core is cut, the first loading seat 311 and the second loading seat 321 move simultaneously, so that the transition piece 50 is inserted into the cutting slit. At this time, the first rubber roller 501 fits the cutting slit just right, providing support for the core. As the loading seat continues to move, the core moves forward under the rolling action of the rubber roller 501. Since the rubber roller 501 can rotate, the friction between the core and the rubber roller 501 is small, and the core can pass through the transition piece 50 smoothly. In this process, the diameter of the rubber roller 501 gradually decreases, which on the one hand adapts to the spatial changes of the core during the movement, and on the other hand, it also plays a role in gradually guiding the core to move toward the tail elastic mechanism 41 and the storage box 60.

[0059] It should be noted that the cutting section elastic mechanism 40 and the tail end elastic mechanism 41 can move back and forth, so the core can expand slightly outwards, all within the rebound range of the cutting section elastic mechanism 40 and the tail end elastic mechanism 41 .

[0060] In some embodiments, the bottom of the storage box 60 has a long groove 601, the first slide rail mechanism 31 and the second slide rail mechanism 32 extend below the long groove 601, and the entrance of the storage box 60 has an inclined surface. The provision of the long groove 601 makes it more convenient for the first slide rail mechanism 31 and the second slide rail mechanism 32 to directly push the cut cores to move into the storage box 60, and the storage box 60 can hold multiple cores at one time.

[0061] In some embodiments, the cutting section elastic mechanism 40 includes a squeeze plate 401, a spring and a base, one end of the spring is connected to the base, and the other end is connected to the squeeze plate 401. The squeeze plate 401 includes two squeeze plates 401, which are respectively arranged at opposite positions on both sides of the bottom of the core, and the squeeze plate 401 can apply squeeze force to the core. The rebound action of the cutting section elastic mechanism 40 and the tail end elastic mechanism 41 is realized by the action of the squeeze plate 401 and the spring, and the squeeze plate 401 can also assist in fixing the core.

[0062] In some embodiments, the first slide rail mechanism 31 and the second slide rail mechanism 32 both include a track 71, a slide 72, and a driver. The slide 72 is slidably connected to the track 71. The first loading seat 311 is connected to the slide 72. The driver is drivingly connected to the slide 72. The two tracks 71 are symmetrical with the cutting center line 20 as the axis.

[0063] In some embodiments, the core cutting device further comprises a protective cover 80, which is arranged outside the first slide rail mechanism 31 and the second slide rail mechanism 32, and the bottom of the protective cover 80 has a slide groove 801 for allowing the first slide rail mechanism 31 and the second slide rail mechanism 32 to move, and the side wall of the protective cover 80 has a cutting opening, and the side wall of the protective cover 80 has a side opening for allowing the extrusion plate 401 to extend into the protective cover 80. By setting the protective cover 80, it is possible to prevent gravel and debris from splashing and causing personal injury.

[0064] In some embodiments, the core cutting apparatus further comprises:

[0065] A high-pressure water spraying mechanism 91, the nozzle of which is tiltedly arranged in the protective cover 80, and is used to spray water toward the core;

[0066] Two force-bearing plates 92 are arranged on the inner wall of the protective cover 80 with the cutting center line 20 as the axis;

[0067] A plurality of pressure sensors are evenly arranged between the stress-bearing sheet 92 and the protective cover 80, the pressure sensors are connected to the stress-bearing sheet 92, and the stress-bearing sheet 92 is fixed by the pressure sensors;

[0068] Two pushing mechanisms 93 are respectively arranged on both sides of the top of the protective cover 80. The two pushing mechanisms 93 are symmetrically arranged with the cutting center line 20 as the axis, and the pushing mechanisms 93 are respectively opposite to the oblique extrusion plates 401. The pushing mechanisms 93 are configured so that during the core cutting process, when the pressure value monitored by the pressure sensor under the corresponding force-bearing piece 92 is abnormal, the control system controls the cutting mechanism 10 to stop, and controls the first slide rail mechanism 31 and the second slide rail mechanism 32 to retreat one core position at the same time, and the pushing mechanism 93 on the same side of the corresponding force-bearing piece 92 pushes the core to move a predetermined distance, and at the same time controls the pushing mechanism 93 on the other side to contract, so that the core is moved, so that the distance between the force-bearing piece 92 on the side with the abnormal pressure value and the core is increased, and the high-pressure water spraying mechanism 91 continues to spray water. After the pressure value monitored by the pressure sensor is normal, the pushing mechanism 93 is reset, and at the same time, the first slide rail mechanism 31 and the second slide rail mechanism 32 drive the core to continue cutting.

[0069] During the core cutting process, the nozzle of the high-pressure water spray mechanism 91 is tiltedly set in the protective cover 80 to spray water to the core, which plays a role in cooling and cleaning the core. Two stress-bearing plates 92 are set on the inner wall of the protective cover 80 with the cutting center line 20 as the axis, and multiple pressure sensors are evenly arranged between the stress-bearing plates 92 and the protective cover 80. The stress-bearing plates 92 are fixed by pressure sensors. When the core is being cut, if the pressure value detected by the pressure sensor under the stress-bearing plate 92 is abnormal, it means that the core has large gravel or cracks during the cutting process, causing part of the core to fall off. At this time, the gravel cannot be flushed out by water flow alone, and the gravel is stuck between the protective cover 80 and the side wall of the core. If the core continues to move, it will inevitably cause the cutting knife to break and the core to break. At this time, the control system will control the cutting mechanism 10 to stop, and control the first slide rail mechanism 31 and the second slide rail mechanism 32 to retreat one core position at the same time, and then the pushing mechanism 93 on the same side of the corresponding force-bearing plate 92 pushes the core to move a predetermined distance, and the pushing mechanism 93 on the other side contracts, so that the core is moved, thereby increasing the distance between the force-bearing plate 92 and the core on the side with abnormal pressure value. After the distance is increased, the gravel can be discharged in conjunction with the high-pressure impact of the water flow. If it cannot be discharged, the pressure sensor remains abnormal, and the machine is shut down for repair to avoid damage to the machine. In this process, the high-pressure water spraying mechanism 91 continues to spray water to cool and clean the core, and it also helps to remove impurities that may affect the cutting. After the pressure value detected by the pressure sensor is normal, the pushing mechanism 93 is reset, and at the same time, the first slide rail mechanism 31 and the second slide rail mechanism 32 drive the core to continue cutting. It should be noted that. Due to the combination of the squeezing plates 401 and the spring in the above-mentioned embodiment, when the core is placed between the squeezing plates 401, it has a tendency to control the core to move to the cutting center line 20. Because the position setting of the squeezing plates 401 cooperates with the operation of the pushing mechanism 93, it is ensured that the axis of the core reset is still in line with the cutting center line 20. Of course, another infrared detection device and reset propulsion motor can also be added to reset the subsequent core.

[0070] In some embodiments, the pushing mechanism 93 includes a bracket 931, a pushing motor 932, and a pushing plate 933. A top opening is provided at the top of the protective cover 80. The pushing plate 933 extends into the protective cover 80 through the top opening. When the pushing plate 933 is in the initial position, it abuts against the side wall of the core. The pushing motor 932 is installed on the bracket 931, and the pushing plate 933 is connected to the driving end of the pushing motor 932. The pushing motor 932 can push the pushing plate 933 to extend and retract. The pushing plate 933 and the extrusion plate 401 include two respectively, two pushing plates 933 are located at the top, and two extrusion plates 401 are located at the bottom, and each plate is spaced ninety degrees apart. Each pushing plate 933 corresponds to an oblique one hundred and eighty degree extrusion plate 401, and the pushing plate 933 moves to shrink the corresponding oblique extrusion plate 401.

[0071] Furthermore, a guide rail 934 is installed on the bracket 931 , and a slider on the guide rail 934 is connected to the driving end of the push motor 932 . The guide rail 934 is parallel to the driving direction of the push motor 932 .

[0072] In some embodiments, the high-pressure water spraying mechanism 91 includes a water pump, a water pipe 911 , and a spray head, and the spray head is installed in the protective cover 80 .

[0073] In some embodiments, the tail elastic mechanism 41 is also provided with a corresponding pushing mechanism 93 to help fix and position the core.

[0074] This embodiment also provides a core cutting method, using the above core cutting equipment.

[0075] Compared with the prior art, the core cutting device and cutting method provided in this embodiment can achieve the following beneficial effects:

[0076] 1. Through the provided cutting mechanism, after the cutting knife is aligned with the core axis, it moves along the cutting centerline direction to cut the core. Specifically, the first loading seat and the second loading seat on the first slide rail mechanism and the second slide rail mechanism are moved to the loading position. The first loading seat and the second loading seat are arranged side by side at this time, and there is a gap in the middle. The core is placed on the first loading seat and the second loading seat. At this time, the axis of the core is in line with the cutting centerline, and the side wall of the core is supported by the first loading seat and the second loading seat from opposite sides to ensure that the core is placed stably. At the same time, the elastic mechanism of the cutting section applies a fixing force to the side wall of the core to further fix the core. The first loading seat and the second loading seat move at the same time, and the core in the blocking space formed on their respective tracks is pushed by the first blocking member and the second blocking member, so that the core is close to the cutting mechanism, and the cutting knife cuts the core. After cutting, a cutting seam is generated, and the first loading seat and the second loading seat move at the same time, so that the transition member is inserted into the cutting seam, to ensure that the core after cutting remains stable under the action of the cutting section elastic mechanism and will not scatter. The setting of the transition member prevents the core from being squeezed by the elastic force and producing a strong collision. Through the transition member, one end of the core continues to move, and through the tail end elastic mechanism, one end of the core passes through the transition member and is gathered by the tail end elastic mechanism until the core is within the range of the tail end elastic mechanism. At this time, the first loading seat and the second loading seat drive the separated core to move at the same time, to ensure that it will not scatter due to different speeds until the core is pushed into the storage box. After the cutting knife is aligned with the core axis, it moves along the cutting centerline to cut. The first slide rail mechanism and the second slide rail mechanism are used to accurately position the core so that the core axis is aligned with the cutting centerline, ensuring the accuracy and precision of the cutting. This precise cutting provides high-quality samples for subsequent core analysis and research, reducing errors caused by cutting deviations.

[0077] 2. The first loading seat and the second loading seat support the side wall of the core from opposite sides to ensure the stable placement of the core. At the same time, the elastic mechanism of the cutting section further applies a fixing force to the core, so that the core will not shake or move during the cutting process, greatly improving the cutting stability. This helps to avoid poor cutting caused by unstable cores and improves the success rate and cutting accuracy of cutting.

[0078] 3. The setting of the transition piece plays a key role in the cutting process. When the cutting produces a cutting seam, the transition piece is inserted into the cutting seam, which not only ensures that the core after cutting remains stable under the action of the cutting section elastic mechanism and will not scatter, but also avoids the core from being damaged by strong collision caused by elastic extrusion. This design improves the safety of the core cutting process and protects the integrity of the core.

[0079] 4. The first loading seat and the second loading seat move simultaneously, pushing the core close to the cutting mechanism and continuing to move after cutting. The tail end elastic mechanism gathers one end of the core to ensure that the core will not scatter due to different speeds during movement. Finally, the separated cores are pushed into the storage box for orderly storage. This design of synchronous movement and orderly storage improves work efficiency, reduces the workload of manual sorting, and also facilitates the management and subsequent processing of the cut cores.
