Description

Technical Field

[0001] The invention relates to the technical field of engineering detection, in particular to a concrete drilling and coring device for engineering quality supervision. Background Art

[0002] Concrete coring is a commonly used concrete structure inspection method used to assess concrete quality and strength. This method uses specialized drilling equipment to obtain cylindrical core samples from concrete structures. Laboratory testing is performed on these core samples to measure physical properties such as compressive strength and density. This testing method is widely used in construction, bridge construction, and road construction, and is a crucial tool for ensuring project quality and safety.

[0003] In existing techniques, after drilling and cutting with a drilling device, the core sample is subjected to eccentric vibration hammering, using the impact force of the vibration to separate the bottom of the core sample from the substrate. However, because this method always relies on the irregular impact characteristics of eccentric vibration hammering, the stress distribution during the core sample separation process is uncontrollable, making it difficult to accurately locate the fracture position. This may cause the fracture surface at the bottom of the core sample to tilt and crack, or even cause internal cracks to expand, directly affecting the integrity of the sampling and the accuracy of the test results.

[0004] To sum up, how to solve the problem that the coring method in the existing technology uses eccentric vibration impact force to separate the bottom of the core sample from the matrix, which may cause the fracture surface of the bottom of the core sample to tilt, crack, or even expand the internal cracks, has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a concrete drilling and coring equipment for engineering quality supervision. Summary of the Invention

[0005] To address these issues, the present invention provides a concrete coring device for project quality supervision. Through the design of the coring assembly, a vertical guide rod drives the coordinated action of an inclined wedge and a cutting piece to achieve multi-directional and multi-angle impact and cutting of concrete samples, ensuring a smooth fracture surface. This method not only ensures sample integrity but also improves sampling accuracy.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: A concrete drilling and coring equipment for engineering quality supervision includes a frame and a control system for controlling the operation of the equipment. A moving component for driving the equipment to move, a drilling component for drilling concrete samples, and a coring component for taking concrete samples are symmetrically arranged on both sides of the frame.

[0007] The coring assembly includes a coring bracket fixedly connected to the side of the frame away from the drilling assembly, and a first telescopic member is fixedly connected to the top of the coring bracket; a control system is used to control the extension and contraction of the first telescopic member, and the output shaft of the first telescopic member passes through the coring bracket and is coaxially detachably connected to the coring barrel; a functional channel is opened in the side wall of the coring barrel along its circumference, and vertical guide rods are vertically slidably fitted in the functional channel, and the bottom ends of the vertical guide rods are fixedly connected to inclined wedge blocks; the inner wall of the lower part of the coring barrel is slidably fitted with a cutting piece along its circumference, and the inclined wedge blocks are in contact with the cutting piece, and the inclined wedge blocks can cut the concrete sample when in contact with the cutting piece; the cutting piece is fixedly connected to the first elastic piece, and the end of the first elastic piece away from the cutting piece is fixedly connected to the inner wall of the functional channel.

[0008] The inner wall of the coring barrel is provided with a hammer assembly for driving the vertical guide rod to slide; the inner wall of the coring barrel is also provided with a clamping assembly for clamping the concrete sample; the hammer assembly is used to drive the clamping assembly to operate to complete the coring operation.

[0009] The technical principles of the above scheme are as follows:

[0010] The moving assembly moves the equipment to the desired sampling position, and the drilling assembly is used to drill and cut the concrete sample first. After the drilling and cutting are completed, the moving assembly is used to align the core barrel above the drilling position. The hammer assembly drives the vertical guide rod to slide along the functional channel. The inclined wedge block at its bottom end contacts the cut-off piece and applies radial pressure, forcing the cut-off piece to move toward the center of the core barrel, and accurately cutting the bottom of the concrete sample through shear force. At the same time, the hammer assembly triggers the clamping assembly to apply radial clamping force to the core sample, ensuring that the core sample is lifted synchronously with the core barrel after cut-off to prevent it from falling off. The first elastic member provides a reverse rebound force after the cut-off is completed, pushing the cut-off piece back to its initial position, realizing continuous coring operation.

[0011] The above scheme has the following beneficial effects:

[0012] 1. The present invention utilizes a coring assembly designed with a vertical guide rod to drive the coordinated action of the inclined wedge and the cutting piece, achieving multi-directional and multi-angle impact and cutting of concrete samples, thereby ensuring a smooth fracture surface. This approach not only ensures sample integrity but also improves sampling accuracy.

[0013] 2. This invention automates concrete sampling through the design of its drilling and coring components. Through precise control of the control system, the entire process of drilling, sampling, and cutting can be completed rapidly. Compared to traditional manual sampling methods, this device significantly improves sampling efficiency and reduces the complexity and time cost of manual operation.

[0014] 3. The clamping assembly design of this invention applies radial clamping force simultaneously at the moment of truncation, evenly wrapping the core sample surface and reducing the stress concentration and localized damage caused by traditional vibration hammering. Its adaptive clamping force accommodates samples of varying diameters. After the truncation element precisely cuts off the bottom, the core sample is directly secured and lifted synchronously with the coring barrel, preventing it from falling or secondary damage. This significantly improves core sample integrity and sampling efficiency, while reducing manual intervention and operational risks.

[0015] Furthermore, the hammer assembly includes a hammer member and a second elastic member circumferentially fixedly connected to the inner wall of the coring barrel. The end of the second elastic member remote from the inner wall of the coring barrel is fixedly connected to the hammer member. The hammer member is also hingedly connected to a support rod along its circumference. The end of the support rod remote from the hammer member is hingedly connected to an adjacent vertical guide rod. The inner wall of the coring barrel is provided with a plurality of openings for the support rod to move. The inner wall of the coring barrel is also provided with a force storage assembly for striking the hammer member.

[0016] Beneficial Effects: The synergistic effect of the hammer and the second elastic member avoids the random fracture caused by traditional eccentric vibration hammering, ensuring a smooth shear surface and precise positioning, and reducing internal damage to the core sample. The energy storage component pre-accumulates energy and releases it instantly to strike the hammer. The buffering effect of the second elastic member and the leverage effect of the support rod improve energy utilization efficiency.

[0017] Furthermore, the force storage assembly includes a magnetic block vertically slidably connected to the inner wall of the core barrel, and there is a closed chamber between the magnetic block and the inner top wall of the core barrel, and the inner top wall of the core barrel is fixedly connected to a second telescopic member; the control system is used to control the extension and retraction of the second telescopic member, and the output shaft of the second telescopic member is fixedly connected to a first electromagnet, and the first electromagnet is magnetically matched with the magnetic block, and the control system is used to control the opening and closing of the first electromagnet; a number of third elastic members are fixedly connected to the inner top wall of the core barrel, and the bottom ends of the third elastic members are all fixedly connected to the magnetic blocks.

[0018] Beneficial Effect: When the second telescopic member pushes the first electromagnet downward, power is applied to the magnet, compressing the third elastic member to accumulate elastic potential energy and squeezing the air energy between the magnet and the core barrel. After power is removed, the magnet, driven by the rebound force of the third elastic member and the kinetic energy of the air, instantly plunges downward, generating an impact force that precisely strikes the hammer member, triggering the cutoff action. The sliding fit of the magnet and the buffering effect of the third elastic member reduces damage to the equipment caused by rigid collisions, while ensuring the vertical impact direction, preventing cutoff deviation, improving the smoothness of the core sample fracture and the success rate of coring. This makes it suitable for efficient and non-destructive sampling of high-strength concrete.

[0019] Furthermore, the clamping assembly includes a number of clamping blocks that are slidably fitted on the inner wall of the core barrel, and the ends of the clamping blocks close to the vertical guide rod are fixedly connected to the fourth elastic member; the ends of the fourth elastic members away from the clamping blocks are fixedly connected to the inner wall of the functional channel, and the vertical guide rods are fixedly connected to a number of resistance blocks that are in contact with the clamping blocks, and the resistance blocks can clamp the concrete samples when in contact with the clamping blocks; a second electromagnet is also embedded in the top of the hammering member, and the second electromagnet is magnetically matched with the magnetic block, and the control system is used to control the opening and closing of the second electromagnet.

[0020] Beneficial Effects: Precise clamping is achieved through the mechanical linkage of the resistance block and clamping block, coupled with control by a second electromagnet. As the vertical guide rod moves, the resistance block squeezes the clamping block, overcoming the resistance of the third elastic member and sliding radially toward the core sample, creating a uniform clamping force. The second electromagnet interacts with the magnetic block to maintain a stable clamping force. Upon power failure, the third elastic member resets and releases the core sample. Its adaptive elastic design accommodates core samples of varying diameters, avoiding surface damage caused by rigid clamping. Electromagnetic control also achieves precise synchronization between clamping and cutting, preventing core sample dropout or displacement, thereby improving sampling integrity and operational efficiency.

[0021] Furthermore, the drilling assembly includes a drilling bracket fixedly connected to the side of the frame away from the coring bracket, a first power member is fixedly connected to the top of the drilling bracket, and the control system is used to control the rotation of the first power member; the output shaft of the first power member passes through the drilling bracket and is coaxially fixedly connected to a screw rod, the screw rod is threaded with a support seat, and the support seat is vertically slidably matched with the drilling bracket.

[0022] A drilling rod is rotatably connected to the support base, and a drilling barrel is coaxially and detachably connected to the bottom end of the drilling rod. A second power element is fixedly connected to the frame, and a control system is used to control the rotation of the second power element. The output shaft of the second power element is in driving engagement with the drilling rod. The drilling rod has an injection channel for cooling water, and the bottom of the drilling barrel has several spray holes connected to the injection channel. A guide sleeve is detachably connected to the bottom of the frame to guide the drilling barrel during drilling. The guide sleeve is also equipped with a mud scraper assembly for scraping mud and sand from the drilling barrel.

[0023] Beneficial Effects: Precise feed control is achieved through the threaded fit of the screw and support base. The first power element drives the screw to rotate, causing the support base to rise and fall smoothly, ensuring the verticality of the drill barrel. The second power element drives the drill rod to rotate at high speed, and combined with the water injection channel to continuously inject cooling water, effectively reducing the drill bit temperature and flushing debris, improving drilling efficiency and core sample quality. The guide sleeve and mud scraper assembly work together to scrape mud and sand from the outer wall of the drill barrel in real time during the drilling process, preventing drill sticking and extending drill bit life. The modular design facilitates the rapid replacement of drill bits of different specifications to accommodate different hole diameters. The overall structure is compact and highly stable, making it suitable for high-precision engineering inspection scenarios.

[0024] Furthermore, the scraper assembly includes a trapezoidal cylinder rotatably connected to the top of the guide sleeve, with a sliding block fixedly connected to the bottom of the trapezoidal cylinder along its circumference; the bottom end of the screw is coaxially fixedly connected to a rotating disk, and the bottom of the rotating disk is eccentrically hinged to a connecting rod; the end of the connecting rod away from the rotating disk is hinged to a sliding plate, which is slidably connected to the frame, and the top of the sliding plate is fixedly connected to an oppositely arranged inclined block; the inclined surfaces of the inclined blocks are in contact with the sliding blocks, and when the inclined blocks respectively contact the sliding blocks, they can drive the trapezoidal cylinder to rotate; a number of scrapers and filter layers are fixedly connected to the inner wall of the trapezoidal cylinder, and the filter layers are all located below the scrapers. The support seat is also equipped with a water absorption component for extracting water accumulated in the trapezoidal cylinder.

[0025] Beneficial Effects: Automated dredging is achieved through mechanical linkage. When the screw drives the rotating disk, the eccentrically hinged connecting rod drives the sliding plate to reciprocate. The contact between the tilting block and the sliding block drives the trapezoidal cylinder to rotate periodically, allowing the scraper to continuously scrape away silt adhering to the outer wall of the borehole cylinder, preventing drill sticking or deflection caused by debris accumulation. The filter layer intercepts silt and cooperates with the water absorption component to pump out accumulated water, realizing cooling water recycling and reducing water waste. The overall structure replaces manual cleaning with mechanical transmission, significantly improving the efficiency of continuous drilling operations, while reducing drill bit wear and maintenance costs, and ensuring the verticality of the drill hole and the quality of the core sample.

[0026] Furthermore, the water absorption assembly includes a water absorption cylinder fixedly connected to the top of the support seat, and the inner wall of the water absorption cylinder is laterally slidingly fitted with a movable plate; the top of the support seat is also fixedly connected to a gear box, and the drilling rod passes through the gear box and is coaxially fixedly connected to the main bevel gear; the main bevel gear is engaged with the secondary bevel gear, and the secondary bevel gear is coaxially fixedly connected to the rotating wheel, and the rotating wheel is rotatably connected to the outer wall of the gear box; the side of the rotating wheel away from the gear box is eccentrically hinged with a transmission rod, and the end of the transmission rod away from the rotating wheel is hinged with a movable rod; the end of the movable rod away from the rotating wheel passes through the water absorption cylinder and is fixedly connected to the movable plate.

[0027] The side of the water suction cylinder away from the movable rod is connected to an input pipe and an output pipe, and the connections between the input pipe, the output pipe and the water suction cylinder are connected to a first one-way valve; one end of the input pipe away from the water suction cylinder is connected to the bottom of the trapezoidal cylinder, and the end of the output pipe away from the water suction cylinder is connected to a filter barrel for filtering accumulated water.

[0028] Beneficial Effects: Efficient drainage and filtration are achieved through mechanical linkage. Rotation of the drill rod drives the primary bevel gear, which in turn drives the secondary bevel gear. This causes the rotating wheel, via an eccentrically hinged transmission rod, to push the movable plate back and forth within the suction cylinder. This creates negative pressure to draw water from the bottom of the trapezoidal cylinder. After being drawn in one way through the inlet pipe, it is pumped into the filter barrel through the outlet pipe for purification and reuse. This solution utilizes the rotational power of the drill rod itself to drive drainage, eliminating the need for additional energy and reducing energy consumption. The filter barrel recycles and purifies accumulated water, reducing cooling water consumption while preventing mud from contaminating the work environment, thereby improving operational efficiency.

[0029] Furthermore, the moving assembly includes several moving wheels, and a groove is opened at the bottom of the frame; the top wall in the groove is fixedly connected to a third telescopic member, and the control system is used to control the third telescopic member to extend and retract; the output shaft of the third telescopic member is fixedly connected to the wheel plate, and the moving wheel is symmetrically connected to the bottom of the wheel plate; the top wall in the groove is also fixedly connected to several telescopic rods, and the bottom ends of the telescopic rods are all fixedly connected to the wheel plate.

[0030] Beneficial Effects: The third telescopic member drives the wheel plate and telescopic rod to rise and fall in tandem, enabling the moving wheels to quickly extend or retract into their grooves. During movement, the third telescopic member extends, allowing the moving wheels to touch the ground and support the equipment's flexible movement. During drilling or coring operations, the moving wheels retract, allowing the bottom of the frame to directly contact the ground. This leverages the machine's weight to enhance stability and prevents the sway or shifting of traditional fixed wheels caused by uneven surfaces. The telescopic rod provides rigid support, preventing deformation of the wheel plate. The compact design reduces space usage, improves adaptability, and balances ease of movement with operational stability.

[0031] Furthermore, an extrusion cylinder is fixedly connected to the frame, and an extrusion plate is vertically slidably fitted on the inner wall of the extrusion cylinder; an extrusion rod is fixedly connected to the top of the extrusion plate, and the top end of the extrusion rod passes through the extrusion cylinder and is fixedly connected to the outer wall of the support seat.

[0032] The bottom of the extrusion cylinder is connected to a water inlet pipe and a water outlet pipe, and the connections between the water inlet pipe and the water outlet pipe and the extrusion cylinder are connected to a second one-way valve; the end of the water inlet pipe away from the extrusion cylinder is connected to the bottom of the filter barrel, and the end of the water outlet pipe away from the extrusion cylinder is connected to the water injection channel.

[0033] Beneficial Effects: Cooling water circulation is achieved through mechanical linkage. As the support seat rises and falls, the extrusion rod drives the extrusion plate up and down. When pressed downward, the volume of the extrusion barrel decreases, and the outlet pipe presses filtered cooling water into the water injection channel of the drilling barrel. When lifted, negative pressure is created inside the barrel, opening the one-way valve in the water inlet pipe and drawing water from the filter barrel for replenishment. The system utilizes the drilling action to synchronize water circulation, eliminating the need for an additional water pump and reducing energy consumption. It also ensures a continuous supply of cooling water to the drill bit, providing real-time cooling and flushing of debris, improving drilling efficiency and bit life. Combined with the filter barrel, it achieves water recycling, balancing efficient operation with environmental protection needs. It features a compact structure and low maintenance costs.

[0034] Furthermore, the control system includes the following modules:

[0035] The acquisition module is used to collect sample data and equipment data required for the quality supervision project, and transmit the collected sample data and equipment data to the information processing module.

[0036] The information processing module is used to match the equipment data according to the requirements of the sample data of the quality supervision project collected by the collection module.

[0037] The information classification module is used to classify equipment data into pre-preparation data, sampling data, coring data and post-sampling data according to the requirements of concrete drilling sampling.

[0038] The error correction module is used to match and compare the classified device data with the real-time data. When a discrepancy is found between the device data and the real-time data, the real-time data is checked and corrected.

[0039] The control module is used to control the operation of the equipment according to pre-preparation data, sampling data, coring data and post-sampling data to perform drilling and coring.

[0040] The alarm module is used to monitor and collect abnormal data during equipment operation in real time and issue an alarm for abnormal data.

[0041] Beneficial effects: The acquisition module can collect sample data and equipment data in real time, including key parameters of power components and magnetic components, and match and process them through the information processing module; ensuring the accuracy and completeness of the data, and providing a reliable basis for subsequent decision-making. At the same time, the information classification module classifies the data according to the operation process, making the decision-making process clearer and more efficient. The control module can intelligently control the different stages of the equipment based on pre-preparation data, sampling data, coring data and post-sampling data. It ensures the continuity and stability of the operation process and improves operation efficiency. At the same time, the error correction module and the early warning module can promptly detect and correct inconsistencies between data and predict abnormal signals, further enhancing the accuracy and reliability of the operation process.

[0055] The following is further described in detail through specific implementation methods:

[0056] Example 1:

[0057] As attached Figure 1As shown: A concrete drilling and coring equipment for engineering quality supervision includes a frame 1 and a control system for controlling the operation of the equipment. A moving component for driving the equipment to move, a drilling component for drilling concrete samples, and a coring component for taking concrete samples are symmetrically provided on both sides of the frame 1.

[0058] The coring assembly includes a coring bracket 2 fixedly connected to the frame 1 on the side away from the drilling assembly by bolts, and a first telescopic member 12 is fixedly connected to the top of the coring bracket 2 by bolts. In this embodiment, the first telescopic member 12 is a cylinder; the control system is used to control the first telescopic member 12 to extend and retract, and the output shaft of the first telescopic member 12 passes through the coring bracket 2 and is coaxially detachably connected to the coring barrel 3; combined with Figure 2 As shown, a functional channel is opened along the circumference of the side wall of the core barrel 3, and a vertical guide rod 4 is vertically slidably fitted in the functional channel. The bottom end of the vertical guide rod 4 is fixedly connected with an oblique wedge 5 by screws; Figure 10 As shown, the inner wall of the lower portion of the core barrel 3 is slidably fitted with a cutoff piece 6 along its circumferential direction. In this embodiment, the cutoff piece 6 is sharpened on the side away from the functional channel, and its sharpness is made of diamond material; the oblique wedge blocks 5 are in contact with the cutoff piece 6, and the oblique wedge blocks 5 can cut the concrete sample when in contact with the cutoff piece 6; the cutoff piece 6 is fixedly bonded with a first elastic member 7, and the end of the first elastic member 7 away from the cutoff piece 6 is fixedly bonded to the inner wall of the functional channel.

[0059] The inner wall of the coring barrel 3 is provided with a hammer assembly for driving the vertical guide rod 4 to slide; the inner wall of the coring barrel 3 is also provided with a clamping assembly for clamping the concrete sample; the hammer assembly is used to drive the clamping assembly to operate to complete the coring operation.

[0060] The hammer assembly includes a hammer member 8 and a second elastic member 9 fixedly connected to the inner wall of the core barrel 3 by a circumferential screw. In this embodiment, the hammer member 8 is made of high-strength alloy material; Figure 3 As shown, the end of the second elastic member 9 away from the inner wall of the core barrel 3 is fixedly connected to the hammer member 8 with screws; the hammer member 8 is also hinged with a support rod 10 along its circumference. In this embodiment, the support rod 10 and the second elastic member 9 are staggered. The end of the support rod 10 away from the hammer member 8 is hinged to the vertical guide rod 4 adjacent to it; the inner wall of the core barrel 3 is provided with a plurality of openings for the support rod 10 to move.

[0061] The inner wall of the core barrel 3 is also provided with a power storage assembly for striking the hammer 8. The power storage assembly includes a magnetic block 11 vertically slidably connected to the inner wall of the core barrel 3. In this embodiment, a buffer layer is coated on the outer wall of the magnetic block 11, so that the magnetic block 11 has magnetic force and high strength. There is a closed chamber between the magnetic block 11 and the inner top wall of the core barrel 3. Through the design of the closed chamber, the accumulation and release of air pressure can be achieved, thereby achieving a greater impact force to achieve a hammering effect. The inner top wall of the core barrel 3 is screw-fixedly connected to a second telescopic member 13. In this embodiment, the second telescopic member 13 is an electric control cylinder. The control system is used to control the extension and contraction of the second telescopic member 13. The output shaft of the second telescopic member 13 is screw-fixedly connected to a first electromagnet 14. The first electromagnet 14 is magnetically matched with the magnetic block 11. The control system is used to control the opening and closing of the first electromagnet 14. The inner top wall of the core barrel 3 is screw-fixedly connected to a plurality of third elastic members 15. The bottom ends of the third elastic members 15 are all screw-fixedly connected to the magnetic block 11.

[0062] Specifically, after the drilling operation is completed, the coring barrel 3 is lowered to the coring area via the first telescopic member 12. The control system activates the second telescopic member 13 (electrically controlled cylinder) to push downward, causing the first electromagnet 14 to contact the magnetic block 11 and energize it for adsorption. The output shaft of the second telescopic member 13 is then controlled to retract, causing the magnetic block 11 to move upward synchronously with the second telescopic member 13 within the closed chamber, compressing the third elastic member 15 to accumulate elastic potential energy; and compressing the gas within the closed chamber, thereby converting mechanical energy into air internal energy. At this point, the hammer member 8 is stationary, and the support rod 10 maintains its initial angle with the vertical guide rod 4.

[0063] When the magnet 11 reaches the preset height, the first electromagnet 14 is de-energized. The instantaneous disappearance of the retaining force causes the magnet 11 to plunge downward at high speed, driven by the rebound force of the third elastic member 15. During this process, the air's internal energy is rapidly released and converted into air kinetic energy. The compressed air, at this moment, generates a powerful shock wave and impact force on the magnet 11 at an extremely high speed, which then strikes the top of the hammer 8. The hammer 8 moves downward under the impact, while the support rod 10 swings about the hinge point. The fixed effect of the through-hole causes the support rod 10 to tilt. As the support rod 10 tilts, it drives the adjacent vertical guide rod 4 upward along the functional channel.

[0064] As the vertical guide rod 4 moves upward, the angled wedge 5 at its bottom radially compresses the cutoff piece 6, forcing it to move instantaneously toward the center of the coring barrel 3. This instantaneous shear force severs the bottom of the concrete core sample, creating a corresponding fracture at the end of the concrete sample. Combined with the downward hammering force of the top hammer 8, the impact forces at both ends act together to shear and remove the concrete sample. This method allows the core sample to be separated from the concrete matrix, reducing the problem of inconsistent fracture positions at the bottom caused by removing the sample only from the top, which can affect subsequent testing.

[0065] Combine Figure 10 As shown, the clamping assembly includes several clamping blocks 16 that slideably fit within the inner wall of the coring barrel 3. In this embodiment, the clamping blocks 16 are made of an elastic material and have arc-shaped ends to provide a flexible grip on the concrete sample, protecting its integrity. A fourth elastic member 17 is fixedly bonded to the end of each clamping block 16 near the vertical guide rod 4. In this embodiment, the first elastic member 7, the second elastic member 9, the third elastic member 15, and the fourth elastic member 17 are all springs. The end of each fourth elastic member 17 away from the clamping block 16 is fixedly bonded to the inner wall of the functional channel. Several resistance blocks 18 are screw-fastened to the vertical guide rod 4, contacting the clamping blocks 16. The resistance blocks 18 contact the clamping blocks 16 to clamp the concrete sample. A second electromagnet 19 is also embedded in the top of the hammer 8. The second electromagnet 19 magnetically cooperates with the magnet 11, and a control system is used to control the opening and closing of the second electromagnet 19.

[0066] Specifically, when the vertical guide rod 4 moves upward with the hammer 8, the resistance block 18 moves upward synchronously and contacts the clamping block 16, pushing the clamping block 16 to overcome the resistance of the fourth elastic member 17 and slide radially toward the concrete core sample, evenly wrapping the surface of the concrete sample to form a clamping force; while generating impact force at the upper and lower ends, the clamping force is used to fix the concrete sample, so that it remains stable during the coring process, avoiding the core sample from loosening or falling off due to the cut-off impact. After the concrete sample is cut, the second electromagnet 19 is energized, causing the second electromagnet 19 and the magnetic block 11 to produce mutual repulsion, maintaining the downward movement of the hammer 8, and using the support rod 10 to synchronously move the vertical guide rod 4 upward, bringing the resistance block 18 into contact with the clamping block 16, ensuring that the clamping block 16 continues to press the core sample. When the vertical guide rod 4 moves upward, the cut-off member 6 is used to move outward to clamp the core sample to prevent it from falling, completing the coring of the concrete sample.

[0067] The drilling assembly includes a drilling bracket 20 fixedly connected to the side of the frame 1 away from the coring bracket 2, and the top of the drilling bracket 20 is bolted fixedly connected to a first power member 21. In this embodiment, the first power member 21 is a motor; the control system is used to control the rotation of the first power member 21; the output shaft of the first power member 21 passes through the drilling bracket 20 and is coaxially fixedly connected to a screw rod 22 through a coupling, and a support seat 23 is threaded on the screw rod 22, and the support seat 23 is vertically slidably engaged with the drilling bracket 20.

[0068] A drilling rod 24 is rotatably connected to the support seat 23, and a drilling barrel 25 is coaxially and detachably connected to the bottom end of the drilling rod 24. In this embodiment, the diameter of the drilling barrel 25 corresponds to the diameter of the core barrel 3; a second power member 26 is bolted and fixedly connected to the frame 1. In this embodiment, the second power member 26 is an engine, and the control system is used to control the rotation of the second power member 26; the output shaft of the second power member 26 is coordinated with the drilling rod 24 through a belt transmission. In this embodiment, the belt transmission adopts the principle of existing technology, and its connection method and installation method are not described in detail in this embodiment; a water injection channel for connecting cooling water is opened inside the drilling rod 24. In this embodiment, the cooling water is transported to the water injection channel by an external device water pump or the like; a number of spray holes connected to the water injection channel are opened at the bottom of the drilling barrel 25; a guide sleeve 27 for guiding the drilling barrel 25 for drilling is detachably connected to the bottom of the frame 1.

[0069] Specifically, when drilling a concrete sample, the control system activates the first power element 21 (motor), driving the screw 22 to rotate. This, through threaded engagement, drives the support base 23 to smoothly descend along the drilling bracket 20, aligning the drilling barrel 25 with the guide sleeve 27 and positioning the drill hole. The second power element 26 (motor) is activated, transmitting power to the drilling rod 24 via a belt drive, driving the drilling barrel 25 to rotate at high speed. Cooling water is pumped into the drilling barrel 25 through an injection channel and out through a spray hole, flushing the drill cuttings and cooling the drill bit to prevent overheating. The motor continuously rotates the screw 22, while the support base 23 pushes the drilling barrel 25 downward at a constant rate (e.g., 3-5 cm / min). The drilling barrel 25 rotates, cutting concrete to form a core sample. The debris, along with the cooling water, is discharged through the gap between the outer wall of the drilling barrel 25 and the hole wall. Upon reaching the predetermined drilling depth, the motor reverses, driving the screw 22 in rotation. The support base 23 drives the drilling barrel 25 upward and back out of the guide sleeve 27.

[0070] The guide sleeve 27 is also provided with a scraping assembly for scraping off the mud and sand from the drilling tube 25. Figure 5 Shown and Figure 6As shown, the mud scraper assembly includes a trapezoidal cylinder 28 rotatably connected to the top of the guide sleeve 27, and a sliding block 29 is fixedly bonded to the bottom of the trapezoidal cylinder 28 along its circumference; the bottom end of the screw rod 22 is coaxially fixedly clamped with a rotating disk 30, and the bottom of the rotating disk 30 is eccentrically hinged with a connecting rod 31; the end of the connecting rod 31 away from the rotating disk 30 is hingedly connected to a sliding plate 32, and the sliding plate 32 is slidably connected to the frame 1. In this embodiment, the sliding connection between the sliding plate 32 and the frame 1 can provide a limit for the sliding plate 32 so that it maintains a linear movement trajectory; the top of the sliding plate 32 is fixedly connected with inclined blocks 33 arranged in opposite directions by screws; the inclined surfaces of the inclined blocks 33 are in contact with the sliding blocks 29, and the inclined blocks 33 can drive the trapezoidal cylinder 28 to rotate when they are in contact with the sliding blocks 29 respectively; a number of scrapers 34 and filter layers 35 are fixedly bonded to the inner wall of the trapezoidal cylinder 28, and the filter layers 35 are all located below the scrapers 34. In this embodiment, the scraper 34 and the filter layer 35 are both made of flexible material. The flexible material can be sleeved on the outer wall of the drilling tube 25 to meet the different diameter requirements of the drilling tube 25.

[0071] The support seat 23 is also provided with a water absorbing component for extracting the water accumulated inside the trapezoidal cylinder 28. Figure 7 and Figure 8 As shown, the water absorption assembly includes a water absorption cylinder 36 fixedly connected to the top of the support base 23 by screws, and a movable plate 37 is laterally slidably engaged with the inner wall of the water absorption cylinder 36; a gear box 38 is also fixedly connected to the top of the support base 23 by screws, and the drilling rod 24 passes through the gear box 38 and is coaxially fixedly engaged with a main bevel gear 39; the main bevel gear 39 meshes with a secondary bevel gear 40, and the secondary bevel gear 40 is coaxially fixedly engaged with a rotating wheel 41. In this embodiment, the secondary bevel gear 40 is fixedly engaged with the rotating wheel 41 via a connecting shaft, and the rotating wheel 41 is rotatably connected to the outer wall of the gear box 38; a transmission rod 42 is eccentrically hinged on the side of the rotating wheel 41 away from the gear box 38, and a movable rod 43 is hinged on the end of the transmission rod 42 away from the rotating wheel 41; the end of the movable rod 43 away from the rotating wheel 41 passes through the water absorption cylinder 36 and is fixedly bonded to the movable plate 37. In this embodiment, the connection between the movable rod 43 and the water absorption cylinder 36 can provide a limit for the movable rod 43, so that the movable rod 43 maintains a linear movement trajectory.

[0072] The side of the water suction cylinder 36 away from the movable rod 43 is connected to an input pipe and an output pipe, and the connections between the input pipe and the output pipe and the water suction cylinder 36 are connected to a first one-way valve. In this embodiment, the first one-way valve is used to guide the one-way flow of the medium, so that the fluid flows into the input pipe and then flows out through the output pipe; the end of the input pipe away from the water suction cylinder 36 is connected to the bottom of the trapezoidal cylinder 28, and the end of the output pipe away from the water suction cylinder 36 is connected to a filter barrel 44 for filtering accumulated water; in this embodiment, the filter barrel 44 is installed on the frame 1, and a number of adsorption layers for filtering accumulated water are integrated in the filter barrel 44 to meet the efficiency of recycling accumulated water.

[0073] Specifically, when drilling, overflow of concrete debris and cooling waste water will be generated, causing the cooling waste water to flow to the outside through the guide sleeve 27, and the rotation of the screw 22 drives the rotating disk 30 coaxially fixed at the bottom to rotate synchronously, and the rotating disk 30 drives the sliding plate 32 to slide back and forth through the connecting rod 31 eccentrically hinged at the bottom. The inclined block 33 at the top of the sliding plate 32 moves with the sliding plate 32, and its inclined surface periodically contacts the sliding block 29 at the bottom of the trapezoidal cylinder 28. When the inclined block 33 contacts the sliding block 29, its inclined surface pushes the sliding block 29 to move circumferentially along the trapezoidal cylinder 28, driving the trapezoidal cylinder 28 to rotate around the top of the guide sleeve 27. Figure 5 For example, when the left-side tilting block 33 is pushed to slide rightward, its inclined surface contacts the sliding block 29, causing the trapezoidal cylinder 28 to rotate once clockwise. The spacing between the tilting blocks 33 provides just enough clearance for the sliding block 29 to rotate the trapezoidal cylinder 28. When the right-side tilting block 33 is pulled to slide leftward, its inclined surface contacts the sliding block 29, causing the trapezoidal cylinder 28 to rotate clockwise again. This reciprocating motion drives the rotation of the trapezoidal cylinder 28. The flexible scraper 34 on the inner wall of the trapezoidal cylinder 28 adheres to the outer wall of the drilling cylinder 25 as it rotates, scraping away adhering mud, sand, and debris. The filter layer 35 intercepts concrete debris and prevents it from entering the circulating waterway.

[0074] After the silt is scraped off, the remaining water is sucked out by the input pipe. When the drilling rod 24 rotates, the drilling rod 24 drives the coaxially fixed main bevel gear 39 to drive the secondary bevel gear 40 to engage the transmission, thereby driving the rotating wheel 41 to rotate. The rotating wheel 41 converts the rotational motion into the linear reciprocating motion of the movable rod 43 through the eccentric hinged transmission rod 42. The movable rod 43 pushes the movable plate 37 to slide in the water suction cylinder 36 to Figure 8 For example, when the movable plate 37 moves to the right, the internal volume of the water suction cylinder 36 increases to form a negative pressure, and the water accumulated at the bottom of the trapezoidal cylinder 28 is sucked into the water suction cylinder 36 through the input pipe; when the movable plate 37 moves to the left, the internal volume of the water suction cylinder 36 decreases, and the accumulated water is pressed into the filter barrel 44 through the output pipe, and is purified by the adsorption layer (such as activated carbon) and then reused.

[0075] Combine Figure 4 As shown, the moving assembly includes a number of moving wheels 45, and a groove is opened at the bottom of the frame 1; the top wall in the groove is fixedly connected with a third telescopic member 46 by bolts. In this embodiment, the third telescopic member 46 is an electric control rod, and the control system is used to control the third telescopic member 46 to extend and retract; the output shaft of the third telescopic member 46 is fixedly connected with a wheel plate 47 by bolts, and the moving wheel 45 is symmetrically connected to the bottom of the wheel plate 47 for rotation; the top wall in the groove is also fixedly connected with a number of telescopic rods 48 by bolts, and the bottom ends of the telescopic rods 48 are fixedly connected with the wheel plate 47 by bolts.

[0076] Specifically, the control system activates the extension of the third telescopic member 46, pushing the wheel plate 47 vertically downward along the groove, and the moving wheel 45 contacts the ground; the telescopic rod 48 extends synchronously to provide support for the wheel plate 47. At this time, the equipment is supported by the moving wheel 45 and can be flexibly pushed to the target position. After reaching the working position, the third telescopic member 46 retracts, the traction wheel plate 47 rises, the moving wheel 45 is retracted into the groove, and the bottom of the frame 1 directly contacts the ground, using the weight of the equipment to enhance stability; the telescopic rod 48 contracts synchronously to keep the wheel plate 47 in a compact storage state in the groove, avoiding shaking due to uneven ground during operation. When working on inclined ground, the telescopic rod 48 can independently fine-tune the telescopic amount (such as extending the telescopic rod 48 on one side). In this embodiment, the telescopic rod 48 adopts the principle of existing technology, and its structural connection method will not be introduced in detail in this embodiment. The wheel plate 47 is tilted to compensate for uneven ground, ensuring the overall levelness of the frame 1 and improving the accuracy of drilling and coring.

[0077] The specific implementation process is as follows:

[0078] Before drilling begins, the control system activates the extension of the third telescopic member 46 (electrically controlled rod), pushing the wheel plate 47 downward, and the moving wheels 45 contact the ground to support the equipment. The telescopic rod 48 simultaneously extends to provide rigid support, allowing the moving wheels 45 to flexibly adjust the direction and propel the equipment to the target position. After the guide sleeve 27 is positioned for drilling, the third telescopic member 46 retracts, the moving wheels 45 retract into the groove, and the bottom of the frame 1 contacts the ground, stabilizing the equipment using its own weight.

[0079] The control system activates the first power member 21 (motor), driving the screw 22 to rotate, which in turn drives the support seat 23 downward, so that the drilling barrel 25 is aligned vertically with the ground through the guide sleeve 27. An external water pump delivers cooling water through the water injection channel of the drilling rod 24 to the spray hole of the drilling barrel 25 to flush the drill bit. The second power member 26 (engine) is activated, and the drilling barrel 25 is driven to rotate at high speed (e.g., 1200 r / min) via a belt drive. The motor continuously drives the screw 22, and the support seat 23 presses down at 3-5 cm / min. The drilling barrel 25 cuts the concrete to form a core sample. The screw 22 drives the rotating disk 30 to rotate, which drives the sliding plate 32 to reciprocate through the eccentric connecting rod 31. The tilting block 33 pushes the trapezoidal barrel 28 to rotate; the flexible scraper 34 scrapes off the mud and sand on the outer wall of the drilling barrel 25, and the filter layer 35 intercepts it. The drilling rod 24 rotates synchronously to drive the main bevel gear 39, which drives the secondary bevel gear 40 and the rotating wheel 41 to rotate, and drives the movable rod 43 to move through the eccentric transmission rod 42. The movable rod 43 synchronously drives the movable plate 37 to reciprocate and suck the accumulated water at the bottom of the trapezoidal cylinder 28 into the filter barrel 44 for purification.

[0080] After the drilling and cutting of the concrete sample is completed, the core barrel 3 is moved to the sampling position; the first telescopic member 12 (cylinder) is activated by the control system to push the core barrel 3 down to the top of the concrete core sample formed by the drill hole. The second telescopic member 13 (electrically controlled cylinder) pushes down the first electromagnet 14 to attract the magnetic block 11. After adsorption, the second telescopic member 13 shrinks and the output shaft moves upward, compressing the third elastic member 15 and squeezing the gas in the closed chamber to store energy, thereby compressing the gas in the closed chamber. After the magnetic block 11 reaches the appropriate position, the first electromagnet 14 is powered off, and the magnetic block 11 hits the hammer 8 at high speed under the drive of elastic potential energy and compressed air, and the support rod 10 swings to push the vertical guide rod 4 upward. When the vertical guide rod 4 moves, the inclined wedge block 5 radially squeezes the cut-off member 6, and the sharp part of the cut-off member 6 instantly cuts off the bottom of the core sample and cooperates with the hammering action of the hammer 8 to separate the core sample from the concrete matrix.

[0081] After the core sample is released, the second electromagnet 19 repels the hammer member 8, causing it to move downward and pull the vertical guide rod 4. At this time, the resistance block 18 simultaneously squeezes the clamping block 16, which wraps around the core sample and maintains the clamping force. The first telescopic member 12 retracts and lifts the coring barrel 3 to remove the core sample. After the core sample is removed, the second electromagnet 19 is de-energized, and the clamping block 16, under the action of the fourth elastic member 17, releases the core sample, completing the sampling.

[0082] In the conventional process of extracting concrete core samples, most people use clamps or other tools to directly remove them. However, this will cause fractures or uneven cross-sections in the lower part of the concrete, thereby affecting the actual sampling quality. This embodiment compresses the third elastic member 15 to accumulate elastic potential energy and squeeze the internal energy of the air formed between the magnetic block 11 and the core barrel 3. After power is cut off, the magnetic block 11 is driven by the rebound force of the third elastic member 15 and the kinetic energy of the air, instantly rushing downward to generate an impact force, striking the hammer 8 to trigger the cut-off action. At the same time, the flexible fixation of the clamping block 16 improves the stability of the core sample, allowing the sample to be completely removed to improve the sampling quality.

[0083] Example 2:

[0084] As attached Figure 1 and Figure 9 As shown, the difference from the above embodiment is that an extrusion cylinder 49 is also bolted to the frame 1, and an extrusion plate 50 is vertically slidably fitted on the inner wall of the extrusion cylinder 49; an extrusion rod 51 is fixedly bonded to the top of the extrusion plate 50, and the top end of the extrusion rod 51 passes through the extrusion cylinder 49 and is fixedly connected to the outer wall of the support seat 23 by screws.

[0085] The bottom of the extrusion barrel 49 is connected to a water inlet and outlet pipe. A second one-way valve is connected to each of the two pipes at their junctions with the extrusion barrel 49. The end of the inlet pipe, remote from the extrusion barrel 49, is connected to the bottom of the filter barrel 44, while the end of the outlet pipe, remote from the extrusion barrel 49, is connected to the water injection channel. In this embodiment, the second one-way valve is used to guide the flow of the medium in one direction. Before drilling the concrete sample, purified water from the filter barrel 44 is preferentially pumped into the extrusion barrel 49. During concrete drilling, the purified water is simultaneously delivered to the water injection channel.

[0086] The specific implementation process is as follows: When the support base 23 is driven downward by the screw 22, the extrusion rod 51 simultaneously pushes down the extrusion plate 50, causing the extrusion plate 50 to slide downward within the extrusion barrel 49, reducing the volume within the barrel 49. Purified water is forced into the water injection channel of the drilling rod 24 and ejected through the spray holes of the drilling barrel 25, cooling the drill bit and flushing away debris. This mechanical linkage achieves cooling water circulation, balancing efficient operation with environmental protection, resulting in a compact structure and low maintenance costs.

[0087] Example 3:

[0088] As attached Figure 11 As shown, the difference from the above embodiment is that the control system includes an acquisition module for collecting information, an information processing module for matching and processing data, an information classification module for classifying data, an error correction module for comparing real-time data, a control module for controlling equipment operation and an alarm module for early warning, and each module is connected to each other by signal.

[0105] Error correction processing: When data errors are found, comprehensive inspection and error correction processing are carried out to ensure the accuracy and reliability of the data.

[0106] The control module is used to control the operation of the equipment according to pre-preparation data, sampling data, coring data and post-sampling data to perform drilling and coring.

[0107] Specifically, the control module implementation process is as follows:

[0108] Data reading: Read pre-preparation data, sampling data, core sampling data and post-sampling data from the classified stored data.

[0109] Equipment control: Based on the data read, the equipment is controlled at different stages, such as adjusting the drill bit speed, feed rate and other parameters to perform drilling and coring operations.

[0110] Real-time feedback: Real-time feedback of equipment operating status and operation progress is provided through the data interface to enable timely adjustment of control strategies.

[0111] The alarm module is used to monitor and collect abnormal data during equipment operation in real time and to generate alarms for abnormal data.

[0112] Specifically, the alarm module implementation process is as follows:

[0113] Real-time monitoring: Real-time monitoring of the equipment's operating status and data through the data interface.

[0114] Anomaly detection: Through preset rules or algorithms, in this embodiment, anomaly detection uses a machine learning algorithm, and the machine learning algorithm uses the random forest algorithm for anomaly detection; detect whether the data is abnormal or exceeds the preset range.

[0115] Alarm processing: When abnormal data is found, the alarm mechanism is triggered immediately, such as sound and light alarm, SMS or email notification, etc., so that the operator can take timely measures to deal with it.

[0116] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
