[0031] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, devices, components and / or combinations thereof, but do not preclude the presence or addition of one or more other features, steps, operations, devices, components and / or combinations thereof.
[0032] Referring to Figures 1-9 The utility model provides a technical scheme:
[0033] A kind of ranging structure of rock hole punch survey machine, including bottom plate 1, feed system 2 and rotating power system 3, bottom plate 1 upper end is fixed with feed system 2, rotating power system 3 is installed in feed system 2 side, rotating power system 3 bottom end is connected with sampling assembly 4, sampling assembly 4 inboard is welded with depth measuring assembly 5, sampling assembly 4 includes core sampling tube 41, core sampling tube 41 inboard is set with interlayer cavity 42, depth measuring assembly 5 includes fixed column 51, fixed column 51 outside is slidably provided with with rod sleeve 52, fixed column 51 outside is equipped with compression spring 53, with rod sleeve 52 upper end is fixedly connected with plug column 54, plug column 54 outside is equipped with plug pipe 55, plug pipe 55 inboard is set with scale groove 56, plug pipe 55 upper end is embedded with glass sheet 57, with rod sleeve 52 bottom end is screw-connected with rotary connecting piece 58, rotary connecting piece 58 bottom end is installed with baffle 59, interlayer cavity 42 inboard is provided with movement prompting mechanism 6, movement prompting mechanism 6 includes sliding column 61, sliding column 61 is fixedly connected with lamp holder block 63 for penetration, lamp holder block 63 inboard is installed with light emitting diode 64.
[0034] As a further implementation of the present scheme, the upper end of the core sampling tube 41 is provided with a mounting hole 44, the plug tube 55 is inserted into the mounting hole 44, and the plug tube 55 is fixedly connected with the core sampling tube 41. A light guide strip 43 is embedded at the upper end of the core sampling tube 41, and a part of the light guide strip 43 protrudes outside the core sampling tube 41. The plug column 54 and the plug tube 55 are both provided with multiple, and the positions of the plug column 54 and the plug tube 55 correspond one by one. The outer side of the plug column 54 is attached to the inner side of the plug tube 55. The scale groove 56 is provided with multiple, which are evenly and equidistantly distributed on the inner side of the plug tube 55. Multiple scale grooves 56 are arranged below the glass sheet 57. The plug tube 55 is fixedly connected with the core sampling tube 41 through the mounting hole 44, which avoids the deviation of the plug tube 55 caused by the vibration of the device during sampling, and provides a stable observation reference for the scale groove 56. The outer side of the plug column 54 is attached to the inner side of the plug tube 55, and the two form a close sliding fit, which avoids the shaking or position deviation of the plug column 54 caused by the gap, so that the action of the plug column 54 blocking the scale groove 56 is strictly synchronized with the depth of core advancement. A part of the light guide strip 43 protrudes outside the core sampling tube 41 and can receive the light of the light-emitting diode 64 to form an illumination area, which provides sufficient light source for observation at the plug tube 55, effectively improves the visibility of the scale groove 56 below the glass sheet 57, and avoids reading errors caused by insufficient light. The glass sheet 57 can not only play a sealing protection role to prevent dust and debris from entering the plug tube 55 and affecting the sliding of the plug column 54, but also serve as a clear observation window. The design of one-to-one correspondence and multiple groups of plug columns 54 and plug tubes 55 can monitor the core advancement state according to multiple points, avoiding misjudgment caused by unclear observation of a single monitoring point.
[0035] As a further implementation of the present scheme, the inner side of the sandwich cavity 42 is fixedly provided with a magnetic tube 46, the projection of the magnetic tube 46 in the vertical direction is annular, the inner side of the magnetic tube 46 is bonded with a rubber tube 47, the inner side of the rubber tube 47 is provided with a columnar groove 48, the columnar groove 48 is fixedly bonded with a battery 49, the inner side of the battery 49 is fixedly connected with a flat cable 410, the inner side of the rubber tube 47 is embedded with a metal rod with holes 411, both ends of the metal rod with holes 411 are provided with a jack 412, the magnetic tube 46 forms a uniform magnetic field on the 360° circumference, and the stable disc 65 will be attracted by the magnetic force when it is close, which is automatically centered and has no angle blind area, ensuring that the sliding column 61 is instantaneously coaxially attached to the battery 49. The rubber tube 47 has certain flexibility and insulation, which protects the battery 49 and the flat cable 410 and other components in the columnar groove 48 from damage caused by hard impact, and can avoid short circuit and other situations caused by the charged components such as the battery 49 and other parts.
[0036] As a further implementation of the scheme, the batteries 49 are arranged in pairs, and each pair of batteries 49 is electrically connected by a flat cable 410. The number of flat cables 410 corresponds to the number of hole metal rods 411. The batteries 49 are arranged in multiple groups, and the multiple groups of batteries 49 are arranged in a ring array. The position of the movement prompt mechanism 6 corresponds to the position of the battery 49. The shape of the insertion hole 412 is a circular truncated cone. The insertion hole 412 is axially aligned with the telescopic rod 67. Compared with the traditional circular cable, the flat cable 410 has better flexibility and space utilization. It is not easy to break when impacted. The flat cable 410 forms a series connection between the two batteries 49. At the same time, the number of flat cables 410 corresponds to the number of hole metal rods 411, so that the current transmission path is clear and explicit, avoiding the problem of line confusion and mutual interference. The movement prompt mechanism 6 must be pressed to the corresponding battery 49 to form a power circuit, and light occurs. The arrangement of the ring array of multiple groups of batteries 49 makes it possible that when the rock core is locally missing, the movement prompt mechanism 6 that does not contact the battery 49 will not continue to form a power circuit with the battery 49, and there will be no misjudgment of "one light off, whole circle dark". The insertion hole 412 is opened as a circular truncated cone, which is conducive to the smoother insertion of the telescopic rod 67 into the insertion hole 412. The circular truncated cone structure has a certain guiding effect. Even if the telescopic rod 67 has a certain angle deviation during insertion due to vibration, it can still be more easily aligned with the insertion hole 412 and inserted.
[0037] As a further implementation of this scheme, the upper end of the fixing column 51 is fixed to the top of the inner wall of the core sampling tube 41, and the upper end of the compression spring 53 is also fixed to the top of the inner wall of the core sampling tube 41. The fixing column 51, the sleeve with rod 52, the rotating connector 58, the baffle 59, and the central axis of the core sampling tube 41 are all on the same straight line. The horizontal projection of the baffle 59 is "I" shaped. A baffle 45 is welded to the inner side of the core sampling tube 41 and is locked in the baffle 59. The outer side of the baffle 59 is in contact with the inner side of the core sampling tube 41. After the core enters the core sampling tube 41, the force pushing the baffle 59, the elastic force of the compression spring 53, and the reaction force of the baffle 59 on the core are all transmitted along the central axis of the core sampling tube 41, avoiding eccentric compression due to force deviation, effectively reducing local friction or collision between the core and the tube wall of the core sampling tube 41, and reducing the probability of core breakage or jamming during sampling. During the core extraction stage, the restoring force of the compression spring 53 and the weight of the baffle 59 work together on the core to form a downward stable pressure. This pressure can evenly overcome the friction between the core and the tube wall, allowing the core to be smoothly removed from the sampling tube without the need for external force to knock or pull. This fundamentally avoids core breakage caused by vibration during manual core extraction, ensuring the integrity of the core. The "I"-shaped structure of the baffle 59 provides a precise locking space for the baffle 45. The baffle 45 can directly restrict the upward sliding of the baffle 59, forming a mechanical limit. The outer side of the baffle 59 is tightly fitted to the inner side of the core sampling tube 41. On the one hand, it can form a guiding effect, ensuring that the baffle 59 always slides vertically along the tube wall of the core sampling tube 41. On the other hand, it can reduce the entry of rock debris into the upper structure from the gap between the baffle 59 and the tube wall of the core sampling tube 41, preventing impurities from affecting the operational stability of components such as the compression spring 53 and the rod sleeve 52.
[0038] As a further implementation of the present scheme, the sliding column 61 is sleeved with a reset spring 62 outside, one end of the reset spring 62 is welded with the core sampling tube 41, the other end of the reset spring 62 is welded with the lamp holder block 63, the sliding column 61 is fixedly connected with the stabilizing disc 65, the lamp holder block 63 is welded with the conductive block 66 outside, the conductive block 66 is fixedly provided with the telescopic rod 67 inside, one end of the telescopic rod 67 is fixedly connected with the core sampling tube 41, one side of the stabilizing disc 65 close to the rubber tube 47 is arc-shaped, the lateral projection of the stabilizing disc 65 is annular, the center axes of the sliding column 61, the stabilizing disc 65 and the columnar groove 48 are on the same straight line, the outside diameter of the stabilizing disc 65 is 1.2 times of the diameter of the columnar groove 48, the stabilizing disc 65 is magnetically attracted to the magnetic tube 46, the core sampling tube 41 and the lamp holder block 63 are welded at the two ends of the reset spring 62 respectively, under normal circumstances, the sliding column 61 is slightly stretched due to the magnetic attraction of the stabilizing disc 65 to the magnetic tube 46, and reset tension is provided for the sliding column 61, when the core extrudes the sliding column 61, the magnetic attraction of the stabilizing disc 65 to the magnetic tube 46 overcomes the spring tension of the reset spring 62, the stabilizing disc 65 is adsorbed close to the magnetic tube 46 and blocks the columnar groove 48, the arc-shaped design of one side of the stabilizing disc 65 and the design that the outside diameter of the stabilizing disc 65 is 1.2 times of the diameter of the columnar groove 48 make part of the stabilizing disc 65 be able to embed into the columnar groove 48 without entering it completely, the center axes of the sliding column 61, the stabilizing disc 65 and the columnar groove 48 coincide, which ensures that the thrust of the core extruding the sliding column 61 is transmitted along the axial direction, avoiding the tilting or jamming of the stabilizing disc 65 due to eccentricity, when the lamp holder block 63 moves with the conductive block 66, the telescopic rod 67 can be accurately telescoped along the axial direction, which ensures that the circular table-shaped insertion hole 412 of the hole metal rod 411 is always axially aligned, realizing stable insertion.
[0039] Workflow: When the device is in use, first, the on-site reconnaissance of the survey area is carried out, the rock type, rock layer trend, slope and surface attachments and various environmental conditions are determined, the specific position of the proposed drilling is marked, then the bottom plate 1 is moved to the appropriate position and fixed, then the rotary power system 3 is controlled to move up and down along the feeding system 2, and at the same time the rotary power system 3 is started to rotate, so that the rotary power system 3 drives the sampling assembly 4 to rotate to drill and sample the rock;
[0040] As the sampling component 4 gradually penetrates deeper into the rock, the rock core cut out by the core sampling tube 41 also gradually enters the core sampling tube 41 as it moves. When the cut rock core comes into contact with the depth sounding component 5 installed in the core sampling tube 41, the rock core exerts an upward force on the baffle 59. This causes the baffle 59 to slide on the outside of the fixed column 51 via the rotating connector 58, and the rod sleeve 52 to compress the compression spring 53, causing it to deform. During this process, the outer side of the baffle 59 remains in contact with the inner wall of the core sampling tube 41. Since the baffle 59 is installed at the bottom of the rotating connector 58 and can rotate inside the core sampling tube 41, the rock core can be pushed stably, ensuring a smoother and more continuous sampling process and reducing the risk of rock core breakage or jamming. The rod sleeve 52 slides outside the fixed column 51, driving the plug 54 to be inserted into the plug tube 55. The movement of the plug 54 in the plug tube 55 can be seen through the glass plate 57 installed at the upper end of the plug tube 55. Since the outer side of the plug 54 is in contact with the inner side of the plug tube 55, when the plug 54 moves in the plug tube 55, it will cover multiple scale grooves 56 one by one from top to bottom. This is used to determine the distance from the upper end of the cut rock core to the bottom opening of the rock core sampling tube 41. When the plug 54 completely covers all the scale grooves 56 in the plug tube 55, the bottom end of the baffle 45 just restricts the baffle 59 from continuing to slide upward. At the same time, the rod sleeve 52 can no longer slide outside the fixed column 51. The rotation power system 3 stops running. After ensuring the overall stability of the device, the rotation power system 3 is slowly lifted along the feeding system 2, so that it drives the rock core sampling tube 41 out of the sampling point.
[0041] During the process of the core sampling tube 41 being pulled out from the sampling point, the compression spring 53 recovers its deformation and exerts downward pressure on the rod sleeve 52, which acts on the baffle 59 through the rotating connector 58. The baffle 59, combined with its own gravity, acts on the core. At this time, the core, under its own gravity and the force exerted on it by the baffle 59, will overcome the friction between itself and the inner wall of the core sampling tube 41 and exit from the core sampling tube 41. This can avoid the core breaking due to vibration when the core is taken out of the core sampling tube 41 with the help of external force.
[0042] In the process of core cutting and sampling, when the core enters the core sampling tube 41 to contact the baffle 59, the core will contact the plurality of movement prompt mechanisms 6 corresponding to the position of the battery 49, the core extrudes the sliding column 61, so that the sliding column 61 slides in the interlayer cavity 42, and the fixed lamp holder block 63 is driven to move, when the lamp holder block 63 moves, a pulling force is generated on the reset spring 62 to make the reset spring 62 deform, after the sliding column 61 moves a certain distance, it will extend into the columnar groove 48 and abut against the battery 49, at this time, one side of the arc-shaped setting of the stabilizing disc 65 is embedded in the columnar groove 48 and is subjected to the magnetic attraction of the magnetic tube 46, so as to be kept stable, so that the columnar groove 48 is in stable contact with the battery 49, at the same time, the lamp holder block 63 drives the welded fixed conductive block 66 to move, so that the conductive block 66 pulls the telescopic rod 67, so that the telescopic rod 67 is elongated and inserted into the insertion hole 412 of the hole metal rod 411, at this time, the upper and lower two batteries 49 in a group of batteries 49 and the flat cable 410 connecting the two batteries 49 will form a path with the hole metal rod 411, the telescopic rod 67 inserted into the insertion hole 412, the conductive block 66 and the two sliding columns 61 corresponding to the battery 49 respectively, so that the battery 49 can provide power for the light-emitting diode 64 installed in the lamp holder block 63, so that it emits light and illuminates the interlayer cavity 42, which can be observed through the light guide strip 43 embedded on the upper end of the core sampling tube 41, part of the light guide strip 43 is protrudingly arranged outside the core sampling tube 41, so that the light can pass through the light guide strip 43 to form an illuminated area, which is more convenient for clearly seeing the scale groove 56 on the inner side of the plug tube 55, if the core entering the core sampling tube 41 has a crack, during the continuous deepening or lifting of the core sampling tube 41, the movement prompt mechanism 6 corresponding to the lower battery 49 in the same group of batteries 49 will be temporarily out of contact with the core, at this time, the magnetic attraction of the magnetic tube 46 to the stabilizing disc 65 is not as strong as the pulling force of the reset spring 62 to the lamp holder block 63, which will make the sliding column 61 reset, at this time, the sliding column 61 does not abut against the battery 49, and the light-emitting diode 64 stops emitting light, by observing the brightness change of the light guide strip 43, part of the dimness indicates that part of the movement prompt mechanism 6 is not in contact with the core at this time, which indicates that there is a defect on the surface of the core in the core sampling tube 41 but not completely broken, and the complete extinction indicates that the rock at this place has a fault crack before sampling, and the upper and lower strata are not in contact, when the light guide strip 43 is completely extinguished, the relative position of the rotary power system 3 and the feeding system 2 is recorded, corresponding to the crack upper along depth position, until the light guide strip 43 is lit again, the relative position of the rotary power system 3 and the feeding system 2 is recorded again, corresponding to the crack lower along depth, the longitudinal length of the crack can be accurately obtained through the position difference of the two times of recording, combined with the sampling depth data, the effect of accurately recording the sampling depth, breaking and crack information is achieved, avoiding the broken core being moved or rearranged during extraction and transportation, which leads to the inability to distinguish which is the natural geological crack,Which are artificial cracks generated during sampling or transportation, so as to obtain the original integrity and authenticity of the sampling data.
