[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figure 1-Figure 9 A drilling device for geological exploration engineering comprises a drilling frame 2 located above the land 1, and lifting openings 22 are penetrated at the four corners of the upper surface of the drilling frame 2, and transmission mechanisms are connected to the two ends of the upper surface of the drilling frame 2, and the output ends of the two transmission mechanisms are connected to linkage components, and the other two ends of the linkage components are connected to rotating components, and the other ends of the two rotating components are connected to two lifting components, and the lower ends of the four lifting components respectively penetrate the four lifting openings 22, and the ends of the four lifting components located below the drilling frame 2 are connected to grinding components, and the insides of the four grinding components are connected to anti-loosening components, one end of the drilling frame 2 is fixedly connected to an extension plate 11, and the other end of the extension plate 11 is connected to a tilting mechanism, and the output end of the tilting mechanism is connected to a leveling mechanism, and the lower end of the leveling mechanism is against the land 1, and the inner wall of one side of the drilling frame 2 is fixedly connected to a level sensor 14.

[0026] like Figures 1 to 9As shown, when the drilling device for geological exploration engineering in the present invention is installed and positioned before drilling, it can be divided into the following situations: 1. On the flat land 1 (i.e. parallel to the horizontal plane): At this time, you only need to move the drilling chassis 2 to the drilling position, and then start the two transmission mechanisms at both ends of the drilling chassis 2 at the same time (at the same time, the tilting mechanism and the leveling mechanism are both in the closed state). After the two transmission mechanisms are started, they will simultaneously rotate with the two linkage components, and as the linkage components rotate, the two rotating components at the same end of the drilling chassis 2 can be rotated, and then the two rotating components can be lifted and lowered with the two lifting components at the four corners of the drilling chassis 2, and the lifting components will also rotate with the smoothing components during the lifting process. After the smoothing components rotate, they can be rotated with the anti-loosening components to the inside of the land 1, thereby completing stable support. At this time, normal drilling can be carried out with the drill tool mounted on the upper surface of the drilling chassis 2.

[0027] 2. On a mountain or other slope (i.e., there is an inclined angle with the horizontal plane): In order to enable the drill to drill in a vertical and horizontal direction, after the drilling chassis 2 moves to the drilling position, the horizontal sensor 14 can be used to detect the angle at this time. Then the controller of the drilling device will start the tilting mechanism, so that the tilting mechanism controls the leveling mechanism to remain vertical to the horizontal direction, and then the leveling mechanism is started. After the leveling mechanism is started, the output end extends outward and rests on the slope surface of the land 1 during the extension process, and in the process of resting on the slope surface, the lower end of the drilling chassis 2 is gradually raised, and in the process of raising, the horizontal sensor 14 will continue to work until the drilling chassis 2 is in a horizontal state, and the controller closes the leveling mechanism. At this time, the two transmission mechanisms are opened again respectively, and then the two transmission mechanisms will drill support holes in the land 1 in the same way as the above steps, and keep themselves stable, and then the drilling project can be carried out normally through the drilling tool.

[0028] Special mention should be made here: In actual application, the upper surface of the drilling base frame 2 will normally carry a power system, a drilling tower (drilling frame), drilling tools, a circulation system, a lifting system and a control system, etc., so it is a mature mechanism in the existing drilling rig, so it will not be described in detail here.

[0029] The level sensor 14 may be a tilt sensor, an electronic bubble, an accelerometer, a gyroscope or other devices with equivalent functions commonly used in the market, without specific limitation.

[0030] As a preferred solution of the present invention, protective covers 3 are fixedly connected to both ends of the upper surface of the drilling frame 2, two transmission mechanisms are respectively connected to the outer walls of the two protective covers 3, and the linkage assembly and two rotating assemblies at one end of the drilling frame 2 are both located inside the protective covers 3.

[0031] More specifically, by providing the protective cover 3, firstly, support can be provided for the transmission mechanism, and secondly, shielding and protection can be provided for the linkage assembly and the two rotating assemblies.

[0032] As a preferred solution of the present invention, the transmission mechanism includes a transmission motor 4 and two transmission rods 5, the outer wall of the transmission motor 4 is fixedly connected to the upper surface of the protective cover 3, the output shaft of the transmission motor 4 is fixedly connected to the upper end of one of the transmission rods 5, the two transmission rods 5 are arranged in parallel, and the lower ends of the two transmission rods 5 are rotatably connected to the inner wall of the drilling base 2, the outer walls of the upper ends of the two transmission rods 5 are rotatably connected to the inner wall of the protective cover 3, the two ends of the linkage assembly are respectively connected to the two transmission rods 5, and the two rotating assemblies are respectively connected to the two transmission rods 5.

[0033] More specifically, when it is necessary to control the lifting of the lifting component, it is only necessary to turn on the transmission motor 4 through the controller, and the output shaft of the transmission motor 4 can drive the transmission rod 5 connected to it to rotate, and then the transmission rod 5 can drive another transmission rod 5 to rotate through the linkage component, and then the two transmission rods 5 can drive the two rotating components to rotate together.

[0034] As a preferred solution of the present invention, the linkage assembly includes a chain 25 and two sprockets 24. The two sprockets 24 are respectively sleeved and fixedly connected to the outer walls of the two transmission rods 5. The chain 25 is sleeved on the outer walls of the two sprockets 24, and the chain 25 is meshed with the two sprockets 24. The chain 25 and the two sprockets 24 are both located inside the protective cover 3.

[0035] More specifically, when the transmission motor 4 rotates with the transmission rod 5 connected to it, the sprocket 24 also connected to the transmission rod 5 will rotate together, and then the sprocket 24 will rotate with another sprocket 24 through the chain 25, and then can rotate with another transmission rod 5, and because of the transmission of the sprocket 24 and the chain 25, the two transmission rods 5 (i.e., two rotating components) will maintain the same rotation speed, and thus the lifting heights of the two lifting components at the same end of the drilling base 2 can be controlled to remain consistent.

[0036] As a preferred embodiment of the present invention, the rotating assembly includes a No. 1 gear 26, an anti-slip ring 27, a No. 2 gear 28 and a plurality of sliders 29. The No. 1 gear 26 is sleeved and fixedly connected to the outer wall of the transmission rod 5. The four corners of the upper surface of the drilling base 2 are provided with anti-slip openings 23. The outer wall of the anti-slip ring 27 is rotatably connected to the inner wall of the anti-slip opening 23. The upper end of the anti-slip ring 27 is fixedly connected to the bottom surface of the No. 2 gear 28. The No. 2 gear 28 is meshed with the No. 1 gear 26. The inner wall of the No. 2 gear 28 is fixedly connected to a plurality of sliders 29. The plurality of sliders 29 are all connected to the lifting assembly. The No. 1 gear 26, the anti-slip ring 27, the No. 2 gear 28 and the plurality of sliders 29 are all located inside the protective cover 3.

[0037] More specifically, when the transmission rod 5 rotates, it can drive the No. 1 gear 26 to rotate. After the No. 1 gear 26 rotates, it can drive the No. 2 gear 28 to rotate with the anti-slip ring 27 and the anti-slip mouth 23 as the axis. In the process of rotation, the lifting component inside the No. 2 gear 28 can be rotated synchronously, and the lifting and lowering of the grinding component can be controlled during the rotation.

[0038] As a preferred embodiment of the present invention, the lifting assembly includes an anti-slip plate 6, a threaded rod 7 and a threaded tube 15. The upper surface of the threaded tube 15 is fixedly connected to the bottom surface of the drilling base frame 2, the bottom surface of the anti-slip plate 6 is fixedly connected to the upper end of the threaded rod 7, the lower end of the threaded rod 7 passes through the second gear 28, the lifting port 22 and the threaded tube 15 and is connected to the flattening assembly, the outer wall of the threaded rod 7 is threadedly connected to the inner wall of the threaded tube 15, the side wall of the threaded rod 7 is provided with a plurality of sliding grooves 9, and the outer walls of a plurality of sliders 29 are respectively slidably connected to the inner walls of a plurality of sliding grooves 9.

[0039] More specifically, when the second gear 28 rotates, the threaded rod 7 can be rotated through the abutment between the slider 29 and the slide groove 9. When the threaded rod 7 rotates, it can be lifted and lowered inside the threaded tube 15 through the threads between the threaded tube 15, thereby lifting and lowering the grinding component located at the lower end of the threaded rod 7.

[0040] In addition, because the second gear 28 and the threaded rod 7 are connected through the slider 29 and the slide groove 9, although the second gear 28 can rotate with the threaded rod 7, because the second gear 28 is restricted on the drilling base 2 by the anti-slip ring 27, the threaded rod 7 will also slide in the slide groove 9 through the slider 29 during the rotation process, thereby controlling the threaded rod 7 to rise and fall during the rotation process.

[0041] Furthermore, because the lower end of the threaded rod 7 is connected to the grinding assembly, the threaded rod 7 will also grind the surface of the land 1 through the grinding assembly during its rotation, thereby grinding out a plane or even a pit on the land 1, thereby increasing the stability of the entire drilling device.

[0042] As a preferred solution of the present invention, the grinding assembly includes a support plate 8 and a plurality of grinding blades 16, the upper surface of the support plate 8 is fixedly connected to the lower end of the threaded rod 7, the bottom surface of the support plate 8 is fixedly connected to the upper surfaces of the plurality of grinding blades 16, the plurality of grinding blades 16 are equidistantly distributed on the bottom surface of the support plate 8, the anti-loosening assembly is located inside the support plate 8, and the plurality of grinding blades 16 are all arc-shaped.

[0043] More specifically, when the threaded rod 7 is raised or lowered, the support plate 8 and the grinding blade 16 connected to the threaded rod 7 will be raised or lowered together. Similarly, the anti-loosening component connected to the support plate 8 will also be raised or lowered together.

[0044] In addition, when the threaded rod 7 rotates, the threaded rod 7 will also rotate with the support plate 8 and the grinding blade 16. When the grinding blade 16 rotates, a plane can be scraped on the surface of the land 1. As the threaded rod 7 continues to extend, the support plate 8 will continue to rotate, so the grinding blade 16 will drill a hole in the land 1, thereby increasing the support stability of the entire drilling device and reducing the probability of the device sliding on the slope.

[0045] It should be particularly noted here that the outward end of the grinding blade 16 protrudes from the support plate 8. This arrangement allows the scraped soil to be discharged from the side of the support plate 8 to avoid clogging.

[0046] As a preferred embodiment of the present invention, the anti-loosening component includes a plurality of limit strips 17, a plurality of No. 1 magnets 31, a plurality of connecting rods 32 and a plurality of No. 2 magnets 33. The side wall at the lower end of the support plate 8 is provided with a plurality of storage openings 30. The upper ends of the plurality of connecting rods 32 are rotatably connected to the top surfaces of the plurality of storage openings 30 respectively. The lower ends of the plurality of connecting rods 32 are fixedly connected to one end of the plurality of limit strips 17 respectively. The outer walls of the plurality of limit strips 17 are slidably connected to the inner walls of the plurality of storage openings 30 respectively. The plurality of No. 2 magnets 33 are fixedly connected to the other ends of the plurality of limit strips 17 respectively. The plurality of No. 1 magnets 31 are fixedly connected to the side walls of the plurality of storage openings 30 away from one end of the connecting rods 32 respectively. The plurality of No. 1 magnets 31 repel the plurality of No. 2 magnets 33 respectively. The plurality of limit strips 17 are all arc-shaped, and the bending direction of the arc is the same as the bending direction of the plurality of grinding blades 16.

[0047] More specifically, when the support plate 8 is raised or lowered, the plurality of limit bars 17 , the plurality of No. 1 magnets 31 , the plurality of connecting rods 32 and the plurality of No. 2 magnets 33 connected to the surface of the support plate 8 will also be raised or lowered together.

[0048] In addition, when the support plate 8 and the grinding blade 16 rotate toward the inside of the soil 1, although the second magnet 33 will extend outward with the limit bar 17 due to the repulsive property between the first magnet 31, the inclination direction of the limit bar 17 is the same as that of the grinding blade 16, so it will not affect the plane being ground or the hole being drilled; however, when the grinding blade 16 stops at a certain position, the threaded rod 7 rotates in the opposite direction under the drive of the transmission motor 4. At this time, the limit bar 17 will rotate and open with the connecting rod 32 as the axis due to the repulsive property between the first magnet 31 and the second magnet 33, and during the rotation process, the connecting rod 32 will be inserted into the soil 1, and then a limit can be performed inside the soil 1 through a plurality of limit bars 17, thereby improving the stability of the entire drilling device.

[0049] It should be noted here that when the threaded rod 7 rotates in the opposite direction, it only needs to be rotated until the limit bar 17 is inserted into the soil 1, and it does not need to be rotated continuously. The specific rotation angle can be changed according to the number and expansion angle of the limit bar 17, which is not limited here.

[0050] As a preferred embodiment of the present invention, the tilting mechanism includes a tilting motor 12, two fixed blocks 18 and two rotating rods 19. A rotating opening 21 is provided at one end of the extension plate 11 away from the drilling base frame 2. The upper ends of the two fixed blocks 18 are fixedly connected to the bottom surface of the extension plate 11. The outer wall of the tilting motor 12 is fixedly connected to the side wall of one of the fixed blocks 18. The output shaft of the tilting motor 12 is fixedly connected to one end of one of the rotating rods 19. The outer walls of the two rotating rods 19 are respectively rotatably connected to the inner walls of the two fixed blocks 18, and the two rotating rods 19 and the two fixed blocks 18 are respectively located on both sides of the rotating opening 21. The leveling mechanism is located in the middle of the rotating opening 21, and the two rotating rods 19 are respectively connected to both sides of the leveling mechanism. The leveling mechanism includes a hydraulic rod 10, a trapezoidal plate 13 and two rotating blocks 20. The upper ends of the two rotating blocks 20 are fixedly connected to the outer wall of the hydraulic rod 10. The two rotating blocks 20 are respectively sleeved and fixedly connected to the outer walls of the two rotating rods 19. The output end of the hydraulic rod 10 is fixedly connected to the upper surface of the trapezoidal plate 13, and the inclined surface of the trapezoidal plate 13 is against the ground 1.

[0051] More specifically, when the horizontal sensor 14 detects that the drilling chassis 2 is not in a horizontal state, it will automatically detect the angle between it and the surface of the land 1, and then start the tilt motor 12 through the controller. After the tilt motor 12 is started, the output shaft drives the rotating rod 19 to rotate inside the fixed block 18, and when the rotating rod 19 rotates, it can drive the rotating block 20 to rotate. After the rotating block 20 rotates, it can drive the hydraulic rod 10 and the trapezoidal plate 13 to rotate together, until the hydraulic rod 10 and the trapezoidal plate 13 rotate to an angle perpendicular to the horizontal plane, the controller turns off the tilt motor 12, and the controller turns on the hydraulic rod 10 at the same time, and then the output end of the hydraulic rod 10 extends outward, and one end of the drilling chassis 2 can be lifted by the reaction force of the trapezoidal plate 13 against the surface of the land 1 until the horizontal sensor 14 detects that the drilling chassis 2 is in a horizontal state and stops.

[0052] It should be particularly noted here that the tip of the trapezoidal plate 13 first contacts the ground 1 to increase the insertion speed, and then, after the trapezoidal plate 13 is fully inserted into the ground 1, one end of the drilling base 2 can be lifted upward by the reaction force.

[0053] Finally, it is important to emphasize that: When the output shaft of the transmission motor 4 rotates clockwise with the transmission rod 5 connected to it, the sprocket 24 connected to the transmission rod 5 will rotate with the other transmission rod 5 and the sprocket 24 through the chain 25, and the transmission of the chain 25 is in the same direction, so the two sprockets 24 and the two transmission rods 5 all rotate clockwise, and the two clockwise transmission rods 5 will simultaneously and separately drive the two No. 1 gears 26 to rotate clockwise, so the No. 2 gears 28 respectively meshing with the two clockwise rotating No. 1 gears 26 are both in counterclockwise rotation.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
