Description

Technical Field

[0001] This application belongs to the field of rock sampling technology, specifically a rock core sampling device. Background Technology

[0002] When testing the physical properties of rocks, rock samples must first be prepared. These samples are typically cylindrical and obtained from the rock using specialized core drilling equipment. In the laboratory, the rocks collected in the field are placed on a platform, a drill bit of appropriate size is installed, and the core drilling equipment drives the drill bit to rotate at high speed, obtaining a sample from the rock for subsequent tests, such as compressive strength testing, expansion testing, and permeability testing.

[0003] Because the outer surface of rocks collected in the field may be irregular, it is difficult to control the tilt angle after placing them on the loading platform, making it impossible to accurately sample specific locations on the rock. Current technology adjusts the posture of irregularly shaped rocks by placing wooden blocks underneath them. This method often requires replacing blocks of different thicknesses and making repeated adjustments multiple times, resulting in low operational efficiency. Utility Model Content

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] Please refer to the following: Figures 1 to 4 The following describes a rock core sampling device provided in an embodiment of this application.

[0024] This application provides a rock core sampling device, including a frame 10, a core drilling assembly 20, and a clamping assembly 30.

[0025] The frame 10 is used to provide stable support for the various components installed on it. The frame 10 specifically includes a base 11, a column 12 and a cantilever 13. The base 11 is fixed to the ground and plays a role in stable support. The column 12 is vertically installed on the base 11. One end of the cantilever 13 is connected to the column 12, and the other end extends horizontally to the top of the base 11.

[0026] The core drilling assembly 20 is used to drill holes in rocks to obtain cylindrical rock samples for subsequent testing or experiments. The core drilling assembly 20 specifically includes a drill barrel 21 and a first drive unit 22. The diameter of the drill barrel 21 can be set in various ways. The drill barrel 21 is detachably installed on the cantilever 13, and different models and specifications of drill barrel 21 can be replaced as needed.

[0027] After installation, the drill barrel 21 is positioned above the base 11. The power output end of the first drive component 22 is connected to the drill barrel 21. The first drive component 22 can be a rotary drive device such as a motor, which drives the drill barrel 21 to rotate at high speed around its own axis through common gear transmission, chain transmission, or other methods. During core sampling, the drill barrel 21 rotates and moves downwards, gradually cutting into the interior of the rock. After drilling is completed, the drill barrel 21 is pulled upwards to obtain a cylindrical rock sample.

[0028] When the drill barrel 21 is working, it is driven to rotate by the first drive member 22. At the same time, the drill barrel 21 also needs to move downward at a constant speed. Optionally, the raising and lowering of the drill barrel 21 can be achieved by a drive device such as an electric lifting rod connected to the clamping assembly 30. The electric lifting rod can drive the drill barrel 21 and the first drive member 22 to rise and fall.

[0029] The rock core sampling device provided in this application embodiment can be obtained by adding a clamping component 30 to the existing core sampling machine. The shape, structure and working method of the base 11, column 12, cantilever 13, drill barrel 21 and first drive component 22 are all existing technologies in the field. Users can choose the appropriate specifications and models of the components available on the market according to their own needs.

[0030] The start and stop of the first drive component 22 and the lifting and lowering of the drill barrel 21 can be achieved by manual remote control, control of the equipment's built-in control panel, or automatic control by PLC control program. The above control methods are common in the electromechanical field, and their specific working principles will not be explained in detail.

[0031] The clamping assembly 30 is used to clamp the rock to be drilled. Most of the rocks collected in the field are irregular blocks. The clamping assembly 30 includes a material carrier plate 31, a second driving member 32, and a clamping mechanism 33. The material carrier plate 31 is located below the drill barrel 21 and forms a V-shaped clamping groove. The part of the material carrier plate 31 corresponding to the sharp end of the clamping groove is hinged to the base 11. The second driving member 32 is used to drive the material carrier plate 31 to rotate around the rotation axis of the base 11. Multiple clamping mechanisms 33 are arranged opposite to each other on both sides of the material carrier plate 31. The clamping mechanism 33 has a clamping rod 332 that extends and retracts along the extension direction of the clamping groove. The clamping rod 332 is used to abut against the rock and limit the rock.

[0032] The second driving component 32 is used to drive the material carrier plate 31 to rotate within a certain angle range to adjust the posture of the rock. The second driving component 32 can be a motor or an electric telescopic rod, etc. During the rotation of the rock, the two side walls of the V-shaped clamping groove can support and limit the rock. There is no limit to the specific range of the rotation angle of the material carrier plate 31, which should generally be between 0-90° to meet the usage requirements.

[0033] Compared with the prior art, the beneficial effects of the rock core sampling device provided in this application are: The rock core drilling and sampling device provided in this application includes a frame 10, a core drilling assembly 20, and a clamping assembly 30. The core drilling assembly 20 and the clamping assembly 30 are respectively mounted on the frame 10 and are vertically aligned. The clamping assembly 30 includes a material carrier plate 31, a second driving member 32, and clamping mechanisms 33. The material carrier plate 31 has clamping grooves for accommodating rocks. Multiple clamping mechanisms 33 clamp the rocks from both sides. By changing the extension and retraction lengths of the clamping rods 332 on both sides, the horizontal position of the rocks can be adjusted along the extension direction of the clamping grooves. The second driving member 32 can drive the material carrier plate 31 to rotate within a certain range to adjust the tilt posture of the rocks.

[0034] The second drive unit 32, the material carrier plate 31, and the clamping mechanism 33 work together to enable the drill barrel 21 to perform core sampling at specific locations on the rock. Compared with the adjustment method using pads in the prior art, the operation is more convenient and the clamping force on the rock is also more secure.

[0035] Please see Figures 1 to 4 The material carrier plate 31 includes two plates that intersect each other. One end of the two plates is connected to each other as a whole, and the other end extends outward. A V-shaped clamping groove is formed between the two plates. The angle of the clamping groove can be 80°, 90°, 100°, etc. A clamping mechanism 33 is provided on both sides of the plate.

[0036] The clamping mechanism 33 can be an electrically operated telescopic rod, or it can be a manually adjustable clamping structure. For details, please refer to [link / reference needed]. Figure 3 and Figure 4 The clamping mechanism 33 also includes a fixing block 331 and a handwheel 333. The fixing block 331 is fixedly mounted on the plate and has an adjustment hole that is threadedly engaged with the clamping rod 332. The handwheel 333 is located at the end of the clamping rod 332 away from the material carrier plate 31. Rotating the handwheel 333 can extend or retract the clamping rod 332 to clamp or release the rock.

[0037] Considering that the rock surface may be sloping, please refer to [link / reference needed] for improved clamping effect. Figure 3 and Figure 4A pressure block 334 is hinged to one end of the clamping rod 332 facing the clamping groove. The rotation axis of the pressure block 334 is perpendicular to the axis of the clamping rod 332. During clamping, the pressure block 334 is used to abut against the rock surface. The pressure block 334 is hinged to the clamping rod 332 and can adaptively change its rotation angle to conform to the rock surface. The material of the pressure block 334 can be rubber or wood.

[0038] It should be noted that in order to prevent the pressure block 334 from rotating with the clamping rod 332, the clamping rod 332 should be a two-section structure. The clamping rod 332 includes a screw and a sliding rod. The screw is threadedly engaged with the threaded hole of the fixed block 331. The sliding rod is located at one end of the screw near the clamping groove. The end of the screw is rotatably engaged with the sliding rod. The pressure block 334 is hinged to the sliding rod.

[0039] A stop structure should also be provided between the sliding rod and the screw to prevent them from separating. Both the screw and the sliding rod can be made directly from existing parts on the market, and will not be discussed in detail here.

[0040] Please see Figure 1 and Figure 2 The cantilever 13 has a guide sleeve 131 that slides with the column 12. The rock core sampling device also includes a lifting assembly 40 for driving the cantilever 13 to slide along the column 12. The lifting assembly 40 can be an electric screw jack, which can change the height of the cantilever 13, thereby changing the height of the drill barrel 21 and the first drive member 22.

[0041] It is understandable that the lifting assembly 40, the first drive component 22, and the second drive component 32 can all be directly selected from existing drive products in the electromechanical field. They all need to be connected to the power source during operation, and their specific specifications and usage methods will not be elaborated here.

[0042] Please see Figure 1 and Figure 2 A mounting block 132 is slidably fitted on the cantilever 13 along its own length direction. The drill barrel 21 and the first driving component 22 are respectively mounted on the mounting block 132. The mounting block 132 can drive the drill barrel 21 and the first driving component 22 to move along the cantilever 13, changing the relative position of the drill barrel 21 and the rock.

[0043] The movement of mounting block 132 can be driven by an electric telescopic rod or a hydraulic push rod. When a hydraulic push rod is used, it needs to be connected to a hydraulic pump station and controlled by necessary hydraulic control valves. The hydraulic push rod, hydraulic pump station, and hydraulic valves are all existing technologies, and their specific structures and usage methods will not be described in detail.

[0044] Please see Figures 1 to 3The base 11 includes a first fixed plate 111, a slide 112, and a second fixed plate 113. The first fixed plate 111 is fixed to the ground by anchor bolts or other connecting parts. The slide 112 is disposed on the first fixed plate 111, and a first sliding groove is provided on the upper surface of the slide 112. The length direction of the first sliding groove is perpendicular to the extension direction of the clamping groove. The second fixed plate 113 is disposed on the slide 112 and slides in cooperation with the first sliding groove. The material carrier plate 31 and the second driving member 32 are respectively disposed on the second fixed plate 113. The second fixed plate 113 can drive the material carrier plate 31 and the second driving member 32 to move along the first sliding groove for fine adjustment of the horizontal position.

[0045] To cool the drill barrel 21 during core drilling and extend its service life, the rock core sampling device also includes a cooling assembly. This assembly comprises a water storage tank and a water delivery mechanism. The water storage tank is used to store cooling water, and the water delivery mechanism includes a water pump and cooling water pipes to deliver the cooling water from the storage tank to the contact point between the drill barrel 21 and the rock. During use, the outlet end of the cooling water pipe is aligned with the contact point between the drill barrel 21 and the rock. The cooling water pipe can be held by hand or fixed in place using a support or similar structure.

[0046] To prevent cooling water from contaminating the ground, a water receiving tray is installed on the base 11, located below the material carrier plate 31, to collect the cooling water flowing down from the material carrier plate 31. After sampling, the rock is removed from the material carrier plate 31, and the material carrier plate 31, drill barrel 21, and water receiving tray are cleaned.

[0047] Please see Figure 3 and Figure 4 The inner wall of the clamping groove is provided with multiple second sliding grooves 311 at intervals, and the second sliding grooves 311 are arranged along the extension direction of the clamping groove. The second sliding grooves 311 can serve as flow channels for cooling water discharge, and as needed, some pad components for supporting or limiting the rock can be installed on the second sliding grooves 311. They can be fixed in the second sliding grooves 311 by screws or other fasteners.

[0048] The aforementioned pad can move along the second slide groove 311 and can be fixed with screws after moving to the designated position. The cross-sectional shape of the second slide groove 311 and the first slide groove mentioned above can be a common slide groove shape such as T-shape or dovetail shape, which can prevent the pad and other components from coming out of the groove.

[0049] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
