[0039] like Figures 1 to 8 As shown, a core sample sampling device includes a base module and a support module 4, the base module includes a fixed submodule 1 and a translation clamping submodule 2, the fixed submodule 1 includes a fixed module body 1-1, the fixed module body 1-1 is provided with a core vacancy slot 1-6 and a debris cleaning slot 1-7 connected to the core vacancy slot 1-6; the translation clamping submodule 2 includes a clamping component, the clamping component is slidably connected to the fixed module body 1-1, and one end of the clamping component close to the core vacancy slot 1-6 is provided with a clamping Holding groove; a core fixing groove is provided on the top surface of the clamping component, and a locking piece is also provided on the edge of the core fixing groove of the clamping component, and an end clamping mechanism is provided at the end of the core fixing groove; the support module 4 includes a column 4-2 detachably connected to the fixing module body 1-1 and a beam rocker arm 4-1 connected to the column 4-2, a power combination module 3 for drilling cores is provided on the beam rocker arm 4-1, and a lubrication system is provided on the beam rocker arm 4-1, and the lubrication system includes a movably arranged cooling lubricating liquid conduit 4-4.

[0040] The present application places the core to be sampled into the core vacant slot, and the clamping slot of the clamping component can effectively fix the core to be sampled, and perform axial sampling of the core. After the core to be sampled is placed in the core fixing slot and the core to be sampled is locked by a locking member, the core can be sampled horizontally. The design of the clamping component realizes the collection of axial and horizontal cylindrical test samples, which effectively solves the problem of being unable to collect cylindrical test samples on site.

[0041] In one embodiment, the bottom shoulder of the core vacancy slot 1-6 has a groove, and the gasket 8 is detachably arranged at the bottom of the core vacancy slot 1-6; the debris cleaning slot 1-7 is connected to the groove of the bottom shoulder of the core vacancy slot 1-6. Preferably, the groove of the bottom shoulder is located at the center of the core vacancy slot 1-6, and the size of the shoulder groove is smaller than the size of the core vacancy slot 1-6. The purpose of setting the shoulder groove is to enable the drill bit to extend into the shoulder groove to achieve drilling through the core. By connecting the gasket 8 in the core vacancy slot 1-6, sampling of cores of different sizes can be achieved. The size of the debris cleaning slot 1-7 is compatible with the size of the shoulder groove. By connecting the debris cleaning slot 1-7 and the shoulder groove, it is easy to clean up the waste generated during the sampling process.

[0042] Furthermore, the shape of the core vacancy slot 1-6 can be circular to achieve the sampling of cylindrical cores, and the shape of the core vacancy slot 1-6 can also be square or other shapes to sample cores of different shapes. When the shape of the core vacancy slot 1-6 changes, the shapes of the clamping slot and other components also change accordingly.

[0043] The present application is described below by means of a specific embodiment, which is described using a cylindrical core sample.

[0044] The utility model is mainly used for obtaining cylindrical core samples at geological survey drilling sites, and is mainly composed of several modules such as a base module, a power combination module and a support module, wherein the base module further includes a corresponding upper translation clamping submodule.

[0045] The main function of the base module is to hold and clamp the core, and to provide support for the collection of cylindrical samples. In geological drilling, the core drilled from the ground by the drill rig usually has a fixed diameter, and the core length is relatively large, so it cannot be used directly for experiments. It is necessary to prepare samples of relevant shapes, dimensions and sizes according to the experimental requirements in order to conduct relevant experiments, such as mechanical experiments, permeability experiments and other types of experiments. At this time, cylindrical core samples are needed, and the utility model is designed for collecting such samples. In the process of collecting cylindrical samples, in order to ensure the safety and accuracy of sampling, the core must first be placed and tightened to facilitate the collection of cylindrical samples. At this time, the bottom module is needed to hold and clamp the core.

[0046] The base module includes two submodules, namely a fixed submodule 1 and a translational clamping submodule 2. The two submodules cooperate with each other to complete the bearing and clamping functions.

[0047] The fixed submodule 1 is located at the bottom of the base module and consists of 7 parts, namely the fixed module body 1-1, the fastening rocker arm 1-2, the rocker arm positioning tenon 1-3, the first screw movable bin 1-4 and the second screw movable bin 1-5, the core vacant slot 1-6, the debris cleaning slot 1-7 and the base fixing foot 1-8.

[0048] The fixed module body 1-1 is the main part of the fixed submodule, and other components are based on it and distributed around it. The fixed module body 1-1 is a rectangular parallelepiped structure.

[0049] The core vacancy slot 1-6 is arranged in the middle of the top surface of the fixed module body 1-1. The core vacancy slot 1-6 is a circular groove. The shoulder at the bottom of the core vacancy slot 1-6 forms a small step with the fixed module body 1-1, that is, the shoulder at the bottom of the core vacancy slot 1-6 has a downward groove. The core is placed on the shoulder at the bottom of the core vacancy slot 1-6. The shoulder groove forms a space, which is convenient for drilling through cylindrical samples when drilling axial cores. In addition, a set of annular washers 8 are provided for the sampling device. The washers 8 can be detachably placed in the core vacancy slot 1-6 and cushioned at the bottom of cores of different diameters, so as to facilitate drilling through the core when drilling cylindrical samples longitudinally.

[0050] The debris cleaning grooves are located on both sides of the core vacancy grooves and are connected to the shoulder grooves at the bottom ends of the core vacancy grooves 1-6. The main function is to clean the rock debris generated during the drilling sample collection process.

[0051] The first screw movable chamber 1-4 and the second screw movable chamber 1-5 are arranged in the fixed module body 1-1. The first screw movable chamber 1-4 and the second screw movable chamber 1-5 are cavity structures for placing the screw assembly. The screw assembly is placed in the chamber, and the moving parts on the screw move back and forth in the chamber, so that the rotational motion is converted into the main spatial area of ​​the back and forth motion.

[0052] In the present application, the first screw movable bin 1-4 and the second screw movable bin 1-5 are in the same straight line and are respectively located on both sides of the core vacancy slot 1-6, so that the clamping parts at their output ends move toward or away from one side of the core vacancy slot 1-6.

[0053] The tightening rocker arm 1-2 is fixedly connected to the fixing module body 1-1 and forms a whole with the screw rod component. The screw is rotated manually to drive the screw to rotate, thereby driving the screw movable part to move forward and backward, thereby achieving the purpose of clamping and loosening the core. The output slider of the screw rod assembly is connected to the clamping part to drive the clamping part to rotate. Correspondingly, a screw positioning pin 1-3 is also configured. When the clamping part is in place, the screw positioning pin 1-3 is used to clamp the tightening rocker arm 1-2, so that the tightening rocker arm 1-2 cannot rotate, thereby locking the screw, so that the clamping part remains stationary, and effectively clamping the core.

[0054] In another embodiment, the part driving the screw assembly to rotate can also be in the form of a micro motor, and the rotation of the screw in the screw assembly can also be achieved by rotating the motor. The structure of the fastening rocker arm 1-2 is simpler and more convenient to carry.

[0055] The fixed module body 1-1 is also provided with base fixing feet 1-8 around it, and the base fixing feet 1-8 are used to fix the base module so that it can be firmly attached to the ground or a certain plane, thereby achieving the function of stably supporting the entire device. The number of base fixing feet 1-8 can be increased or decreased according to needs.

[0056] The rear of the fixed module body 1-1 is also provided with a column support component 1-9, which is the main component of the fixed column 4-2. The column support component 1-9 is a trapezoidal body as a whole, with the same height as the fixed module body 1-1, and a square hole is opened in the middle to fix the column 4-2. The bottom of the column support component is connected to the fixed module body 1-1, and the two form a stable base module. At the same time, a gap is reserved between the upper part of the column support component and the fixed module body 1-1 to ensure that the translation clamping module can move normally. There are also fixing bolts on the rear side of the column support component 1-9 for fixing the column.

[0057] The translational clamping submodule 2 is located at the upper part of the base module. The main body is two clamping parts that can move horizontally, mainly including clamping part 1 2-1, clamping part 2-2, core fixing groove 2 2-3, core fixing groove 1 2-4, clamping groove 1 2-6, clamping groove 2 2-5, buckle column 2-7, fastening buckle 2-8, and other parts.

[0058] The clamping component 1 2-1 and the clamping component 2-2 are located on the upper part of the fixed module and are arranged horizontally symmetrically. One side of the clamping component 1 2-1 and the clamping component 2 2-2 is a plane, and one side is designed as a clamping groove (clamping groove 1 2-6, clamping groove 2 2-5). The clamping groove is specifically a V-shaped groove, and the V-shaped groove clamps the core by moving the clamping component. The V-shaped groove mainly clamps the core to prepare for axial collection of cylindrical core samples; with the clamping of the V-shaped groove and the cooperation of the clamping component, axial drilling of cylindrical cores without dead angles can be achieved. In some other embodiments, the shape of the clamping groove can also be changed according to the shape of the test sample, such as being designed as an arc groove or a clamping groove of other shapes.

[0059] The clamping component 1 2-1 and the clamping component 2-2 are connected to the fixed module body 1-1 by a dovetail groove, which can ensure the guidance of the clamping component 1 2-1 and the clamping component 2 2-2. The clamping component 1 2-1 and the clamping component 2 2-2 are connected to the output end of the screw assembly, and under the action of the screw assembly, the clamping component 1 2-1 and the clamping component 2 2-2 can be effectively driven to move.

[0060] The core fixing grooves (core fixing groove 2-3, core fixing groove 1 2-4) are arc-shaped grooves. The core fixing groove 1 2-4 is arranged on the top surface of the clamping component 1 2-1, and the core fixing groove 2-3 is arranged on the top surface of the clamping component 2-2. The main function is to place the core. The core is placed in the core fixing groove, which is more convenient for fixing the core.

[0061] The buckle column 2-7 and the fastening clamp 2-8 are two parts for fastening the core. The buckle column 2-7 is arranged on the front and rear sides of the core fixing groove. The two ends of the fastening clamp 2-8 are respectively connected to the buckle columns 2-7 on the front and rear sides. The horizontally placed core can be firmly fastened by the cooperation of the two. There is a nut on the buckle column. When the fastening clamp is buckled on the column, the purpose of fastening or loosening the core can be achieved by tightening or loosening the nut. The number of the buckle column 2-7 and the fastening clamp 2-8 can be increased or decreased according to actual needs.

[0062] In one embodiment, anti-skid pads are also provided in the core fixing groove 2-3 and the core fixing groove 1-4. The provision of the anti-skid pads can make the core placed therein to be sampled more stable, and the core will not slide during the sampling process.

[0063] Furthermore, an end clamping mechanism 9 is designed at the left end of the core fixing groove 2-3 and the right end of the core fixing groove 1-4. The end clamping mechanism 9 can be a screw clamping member, specifically including a support block 9-1, an extrusion block 9-2, a crank handle 9-3 and a plug rod 9-4. The support block 9 is arranged on the top of the plug rod 9-4, and the screw sleeve is arranged in the support block 9-1.

[0064] For example, a connecting hole is designed at the left end of the core fixing groove 2-3 and at the bottom of the right end fixing groove of the core fixing groove 1-4 (the connecting hole is not a through hole design), and the square plug-in rod 9-4 is plugged into the connecting hole. The connecting hole is a square hole corresponding to the square plug-in rod 9-4. The top of the supporting block 9 is provided with a screw sleeve arranged in the left and right directions. The screw is rotatably arranged in the screw sleeve. An extrusion block 9-2 is provided at the end of the screw. The screw is driven to rotate by rotating the crank handle 9-3, so that the extrusion block 9-2 at its end contacts the end of the core to be sampled, so as to limit the axial direction of the core to be sampled. Combined with the setting of the buckle column 2-7 and the fastening clamp 2-8, the all-round fixing effect of the core to be sampled can be guaranteed.

[0065] The power combination module is the main power combination of the sampling device. The power module uses electric energy as energy and an electric motor as a power device. The power generated by the electric motor is transmitted to the drill bit through a speed change gear combination, thereby drilling a cylindrical core sample that meets the experimental requirements. The power combination module requires a combination of high torque and medium and low speeds to achieve the goal of smoothly drilling samples. The power combination module is fixedly connected to the crossbeam rocker arm 4-1.

[0066] The power combination module mainly includes a main box 3-1, a lifting arm handle 3-2, a drill clamping device 3-3, a lifting auxiliary device 3-4, and a motor 3-5.

[0067] The main box 3-1 contains a speed change gear assembly kit and a main box lifting device, both of which can use universal components. A control button group is set on the outside of the main box to adjust the speed of the drill bit to achieve a reasonable match between the output power and the speed and the corresponding rock. The motor 3-5 is the main power output device in the power combination module and adopts a universal standard motor. The motor is located at the upper part of the main box and is connected to the speed change gear assembly in the main box 3-1 through a transmission shaft.

[0068] The drill bit clamping device 3-3 is arranged at the lower part of the main box. The drill bit clamping device 3-3 is mainly used to clamp coring drill bits of various diameters. The clamping device adopts a three-claw or four-claw structure to clamp the drill bit.

[0069] The lifting arm handle 3-2 is the main component for adjusting the height of the drill bit. The lifting arm handle 3-2 is rotatably connected to the crossbeam rocker arm 4-1, and its output end acts on the drill bit clamping device 3-3 or the drill bit. The height of the drill bit is raised or lowered by rotating the lifting handle. The lifting handle has three grips, which can be alternately held to rotate the lifting arm.

[0070] The lifting auxiliary device 3-4 assists the lifting of the drill bit.

[0071] The support module 4 is an important component for supporting the power assembly module. It is located at the rear of the fixed module as a whole.

Fixing bolts 4-5 are provided on the outer side of the circle and one side of the crossbeam to tighten the connection between the crossbeam and the column; a cooling lubricant bottle 4-3 is also provided on one side of the crossbeam.

[0073] The column 4-2 is the main component supporting the rocker beam 4-1. The column is square, and the upper square joint matches the size of the square through hole on the crossbeam rocker. The upper part is connected to the square hole of the rocker beam through the square joint. The lower part of the column 4-2 is inserted into the square hole of the column support component 1-9. The column support component 1-9 is provided with fixing bolts 4-7 and 4-8. The fixing bolts 4-7 and 4-8 are used to tighten the connection between the column and the support component.

[0074] The cooling lubricant bottle 4-3 is a container for storing cooling lubricant. The container is installed on one side of the beam. A cooling lubricant conduit 4-4 is designed at the bottom. One end of the conduit is connected to the cooling lubricant bottle 4-3 and the other end is arranged above the sampling drilling. It is the main component for cooling and lubricating the drill bit and the core. An exhaust hole is designed on the top of the cooling lubricant bottle.

[0075] The cooling lubricant conduit 4-4 is the main component for guiding the cooling lubricant. One end is connected to the cooling lubricant bottle 4-3, and the other end is arranged above the sampling drilling, so that the cooling lubricant acts on the drill bit and the core. A switch is designed on the cooling lubricant conduit to close or open the cooling lubricant conduit.

[0076] The beam positioning bolts 4-5 are located at one end of the beam outside the circular shape of the beam, and are used to fasten the connection between the beam and the column. A plurality of beam positioning bolts are designed on the circular shape outside as needed.

[0077] The triangular support plate 4-6 is a component supporting the cross beam, and is triangular in shape as a whole. It is located below the cross beam and on one side of the column, and is fixedly connected to the column as a whole.

[0078] The connection between the column and the rocker beam is that the top of the triangular support plate 4-6 is horizontal after the connection, the lower part of the rocker beam is in close contact with the triangular support plate, and the triangular support plate 4-6 and the column 4-2 form a combined force to provide good support for the rocker beam.

[0079] The clamping module is the main component of the sampling device for fixing core samples. According to different clamping characteristics, three clamping buckles are designed, namely buckle one 5, buckle two 6 and buckle three 7. Buckle one mainly includes a buckle body 5-1, an upper buckle 5-2 and a lower buckle 5-3.

[0080] The buckle body 5-1 is the main component of the buckle, which is U-shaped as a whole, with the upper part threadedly connected to the upper buckle 5-2, and the lower part threadedly connected to the lower buckle 5-3. The upper buckle 5-2 is located at the upper part of the buckle body 5-1, and is threadedly connected to the buckle body. It is tightened or loosened by rotation. The bottom of the upper buckle is a disc-shaped joint, and a cylindrical protrusion is designed in the middle of the disc. This design matches the base fixing foot 1-8 on the fixed base. Through the rotation movement of the upper buckle, the function of tightening the foot is achieved. The lower buckle 5-3 is located at the lower part of the buckle body 5-1, and is threadedly connected to the buckle body. It is tightened or loosened by rotation. The bottom of the lower buckle is a disc-shaped joint, which is clamped with the workbench by rotation to tighten the core sample sampling device.

[0081] The sizes of the buckle main body parts of buckle one 5, buckle two 6 and buckle three 7 are different, and correspondingly, the numbers of upper buckles and lower buckles configured are different.

[0091] In summary, the existing patent technology and this patent have different application purposes and results, and it is impossible to obtain regular core samples that meet the experimental requirements at the drilling site. The samples obtained still need to be crushed twice to meet the requirements of the experimental test. The utility model tackles the problem of collecting cylindrical experimental samples on site, and realizes the collection of axial and transverse experimental samples at the field work site through the innovation of the clamping method and the fixing method, which well solves the problem of not being able to collect cylindrical cores on site.

[0092] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
