Description

Technical Field

[0002] There are many types of mineral resource exploration equipment, mainly including drilling equipment, geophysical exploration equipment, geochemical analysis instruments, sampling and testing equipment, etc. The drilling rig is the core equipment of drilling operations. It combines the impact and rotation to break rocks. The impact force generated by the impactor and the rotation force of the drilling rig act together on the drill bit to improve drilling efficiency. It is especially suitable for hard and broken formations.

[0003] In the existing technology, inaccurate positioning of the drill rod will cause the actual drilling trajectory to deviate from the preset trajectory. The positioning error may cause the borehole to completely deviate from the designed path, resulting in the failure of the entire drilling mission. Inaccurate positioning of the drill rod will cause uneven force on the drill tool during the drilling process. Inaccurate positioning of the drill rod will cause uneven force on the borehole wall. In loose formations or broken zones, it is easy to cause the borehole wall to collapse, blocks to fall off, and even cause the drilling to be scrapped. Summary of the Invention

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] Example 1:

[0035] See also Figure 1 - Figure 4As shown, a drilling device for mineral resource exploration and positioning includes a drilling vehicle 1, a drill rod 2 and a fixing frame 3. The drill rod 2 and the fixing frame 3 are arranged at the front end of the drilling vehicle 1, and the drill rod 2 is arranged inside the fixing frame 3. The drill rod 2 of the drilling vehicle 1 can be rotated and extended inside the fixing frame 3, so that the end of the drill rod 2 can be drilled into the ground. Before the drill rod 2 is drilled into the ground, the drill rod 2 needs to be positioned and fixed at the same time. A positioning assembly 4 is provided at the end of the fixing frame 3. The positioning assembly 4 includes three fixing blocks 49. The fixing blocks 49 are arranged in a ring array. The three fixed blocks 49 are arranged in a row on the end face of the fixed frame 3. The internal rotation of the fixed block 49 is connected to the rotating sleeve 410. The internal part of the rotating sleeve 410 is provided with a drill bit 48. The three fixed blocks 49 can make the drill bit 48 face the ground, so that the drill bit 48 can be drilled into the ground for positioning. The center of the circle where the three drill bits 48 are located is aligned with the axis of the drill rod 2. The outside of the drill bit 48 is provided with a spur gear 47. The spur gear 47 rotates synchronously with the outside of the drill bit 48. The spur gear 47 can be restricted to the end of the drill bit 48 by the fixed sleeve 52 so that the spur gear 47 does not move. The drill bit 48 rotates synchronously with the drill bit 48 and can drill the drill bit 48 into the ground. A drive motor 41 is installed on the side wall of the end face of the fixed frame 3. A spur gear 1 42 is installed on the output end of the drive motor 41. The outer ring of the fixed frame 3 is provided with a fixed ring 43. The outer ring of the fixed ring 43 is provided with a bearing 44. The inner ring of the bearing 44 is fixed to the outer ring of the fixed frame 3. A spur gear 2 45 and a spur gear 3 46 are fixedly installed on the outer side of the bearing 44. The spur gear 3 46 is welded to one side of the spur gear 2 45. The spur gear 2 45 and the spur gear 3 46 rotate synchronously. The spur gear 1 42 and The spur gear 2 45 is meshed with each other, the spur gear 3 46 is meshed with the spur gear 4 47, and the three rotating groups of drill bits 48 are used to position the drill rod 2 while preventing the drill rod 2 from shifting. The drive motor 41 drives the spur gear 2 45 to rotate, and the spur gear 2 45 rotates around the bearing 44. The rotating spur gear 2 45 drives the spur gear 3 46 to rotate, and the spur gear 3 46 is meshed with the spur gear 47. At this time, the spur gear 47 drives the drill bit 48 to rotate inside the rotating sleeve 410, thereby drilling the drill bit 48 into the ground. The three groups of drill bits 48 position the drill rod 2.

[0036] See also Figure 3 and Figure 4As shown, a rotating pin 412 is provided between the end face of the fixing frame 3 and the three groups of fixing blocks 49. The middle cross-section of the rotating pin 412 is square, and the two ends of the rotating pin 412 are circular. The rotating pin 412 can rotate the fixing block 49 while rotating, ensuring that the rotating pin 412 and the fixing block 49 rotate synchronously. The outer ring of the rotating sleeve 410 is threadedly connected with a fastening bolt 411, and a threaded hole aligned with the fastening bolt 411 is provided in the middle of the side wall of the drill bit 48. The end of the drill bit 48 is a self-tapping thread, and the middle cross-section of the drill bit 48 is square. The drill bit 48 with a square cross-section rotates along with the spur gear four 47, so that the drill bit 48 drills into the ground.

[0037] See also Figure 3 and Figure 4 As shown, the rotating sleeve 410 is fixed to the threaded hole of the drill bit 48 by the fastening bolt 411. The fastening bolt 411 is used to prevent the spur gear 47 from moving along the axial direction of the drill bit 48. The fastening bolt 411 screwed into the rotating sleeve 410 and the drill bit 48 can limit the movement of the drill bit 48 along the inside of the rotating sleeve 410, and can only ensure that the drill bit 48 and the rotating sleeve 410 rotate. The three groups of fixing blocks 49 are fixed to the fixing frame 3, and the end faces of the three groups of fixing blocks 49 are flush with the end faces of the fixing frame 3, and the axis of the drill bit 48 is parallel to the axis of the drill rod 2. The center of the circle where the three groups of drill bits 48 are located is aligned with the axis of the drill rod 2. The drill bit 48 is facing the ground and can drill the drill rod 2 into the ground. The three groups of drill bits 48 prevent the drill rod 2 from deflecting.

[0038] It should be noted that when prospecting for mineral resources, the drill rod 2 needs to be drilled into the ground. The fastening bolt 411 is screwed into the threaded hole of the drill bit 48 in advance to prevent the drill bit 48 from moving along the axis of the rotating sleeve 410, and the drill bit 48 and the spur gear 47 are restricted inside the fixed sleeve 52. The spur gear 47 rotates to drive the drill bit 48 to rotate, and the drill rod 2 is pointed at the place where the hole needs to be drilled. The three sets of drill bits 48 position the drill rod 2. At this time, the drive motor 41 can drive the spur gear 1 42, and the spur gear 47 can rotate. The first gear 42 drives the second spur gear 45 to rotate. Since the second spur gear 45 and the third spur gear 46 rotate relative to the fixed ring 43 through the bearing 44, the rotation of the third spur gear 46 can drive the fourth spur gear 47 to rotate, and the fourth spur gear 47 drives the drill bit 48 to rotate. The fourth spur gear 47 is restricted inside the fixed sleeve 52, and the fastening bolt 411 restricts the drill bit 48 from moving along the axial direction. The three groups of drill bits 48 can drill into the ground. The three groups of drill bits 48 can be used to position the drill rod 2 and prevent the position of the drill rod 2 from shifting.

[0039] Example 2:

[0040] See also Figure 2 、 Figure 5 - Figure 7As shown, a tilting assembly 5 is provided between the spur gear 2 45 and the fixed block 49, and the tilting assembly 5 includes a bevel gear 1 51, which is welded to the side wall of the spur gear 2 45, and the spur gear 3 46 and the bevel gear 1 51 are arranged opposite to each other. A bevel gear 2 53 is provided on the outside of the drill bit 48 and on one side of the spur gear 4 47, and the bevel gear 2 53 is welded to the spur gear 4 47. The bevel gear 2 53 is meshed with the bevel gear 1 51 to drive the drill bit 48 to rotate, and the bevel gear 2 53 and the spur gear 4 47 are both slidably connected to the drill bit 48. The drill bit 48, the fixed block 49 and the bevel gear 1 51 are rotated around the fastening bolt 411, so that the three drill bits 48 are rotated around a specific angle, and the meshing of the spur gear 3 46 and the spur gear 4 47 is transformed into the meshing of the bevel gear 1 51 and the bevel gear 2 53, so that the driving motor 41 can drive the bevel gear 1 51 and the bevel gear 2 53 to rotate The drill bit 48 rotates around the bevel gear 2 53, thereby tilting the three groups of drill bits 48 so that the end of the drill bit 48 faces the ground, and when the fixing frame 3 is pressed down, the self-tapping thread at the end of the drill bit 48 can enter the ground. The side wall of the drill bit 48 is provided with a sliding groove 54, and the end of the fastening bolt 411 is slidably connected with the sliding groove 54. The fastening bolt 411 and the sliding groove 54 are used to rotate the drill bit 48 while the drill bit 48 moves along the axis of the rotating sleeve 410. The three groups of drill bits 48 are tiltedly arranged on the end face of the fixing frame 3. The three groups of drill bits 48 are tilted and inserted into the base at the same time for positioning the drill rod 2. Since the end of the three groups of drill bits 48 enters the ground, the rotating drill bit 48 continues to enter the ground under the action of the self-tapping thread, and the fastening bolt 411 of the fixed block 49 moves along the sliding groove 54 of the drill bit 48, and the drill bit 48 continues to extend into the ground.

[0041] See also Figure 6 and Figure 7 As shown, the outer walls of the three groups of fixed blocks 49 are welded with fixed sleeves 52, and the spur gear four 47 and the bevel gear two 53 are both located inside the fixed sleeve 52. The spur gear four 47 and the bevel gear two 53 are confined inside the fixed sleeve 52. The drill bit 48 is driven by the bevel gear two 53 to rotate. The drill bit 48 is connected to the internal rotation of the fixed sleeve 52. The corner of the fixed block 49 is against the edge of the fixed frame 3. The three groups of drill bits 48 rotate around the rotating pin 412. At this time, the fixed block 49 is against the edge of the fixed frame 3, and the drill bit 48 is arranged at an angle so that it can be inserted into the ground at an angle.

[0042] See also Figure 6 and Figure 7As shown, a square groove 55 is provided inside the rotating sleeve 410 that is adapted to the cross-section of the drill bit 48. The rotating sleeve 410 is used to ensure that the rotating sleeve 410 and the drill bit 48 rotate synchronously. The three groups of fixed blocks 49 rotate around their respective rotating pins 412. The spur gear 47 and the bevel gear 2 53 rotate around the rotating pin 412. The fixed block 49 rotates around the rotating pin 412 so that the bevel gear 1 51 and the bevel gear 2 53 can be engaged.

[0043] It should be noted that when the drill bit 48 needs to be inserted into the ground at an angle, the drill bit 48 and the fixed block 49 can be rotated around the rotating pin 412, so that the spur gear 47 and the bevel gear 2 53 can also rotate around the rotating pin 412, so that when the corner of the fixed block 49 is against the edge of the fixed frame 3, the bevel gear 1 51 and the bevel gear 2 53 are engaged. At this time, the driving motor 41 drives the spur gear 2 45 to rotate, so that the bevel gear 1 51 drives the bevel gear 2 53 to engage, and the drill bit 48 rotates around the rotating sleeve 410. The drill bit 48 with the self-tapping bolt is moved, thereby drilling into the ground. Since the fixing frame 3 is pressed downwardly toward the ground, it is conducive to the drill bit 48 drilling into the ground, and the fastening bolt 411 slides along the inner sliding groove 54 of the drill bit 48, thereby ensuring that the drill bit 48 rotates while driving the drill bit 48 to continue to enter the ground. When the drill rod 2 just contacts the ground, the three groups of drill bits 48 enter the ground first. At this time, not only can the three groups of drill bits 48 be used to position the drill rod 2, but the inclined drill bit 48 can also enter the ground more securely.

[0044] Example 3:

[0045] See also Figure 2 、 Figure 8 - Figure 11As shown, a locking assembly 6 is provided at the edge of the fixing frame 3 and at one end of the rotating pin 412. The locking assembly 6 includes a fixing box 61, which is welded to the edge of the fixing frame 3. A fixing groove 62 is provided inside the fixing box 61. A rotating ring 63 and a knob 64 are provided at the end of the rotating pin 412 and located inside the fixing box 61. The rotating pin 412, the rotating ring 63 and the knob 64 rotate synchronously. When the drill bit 48 and the fixing block 49 rotate, the rotating ring 63 will be driven to rotate synchronously to ensure that the rotating pin 412 is driven to rotate when the fixing block 49 rotates. The rotating ring 63 can be used to limit the rotation of the rotating pin 412. Four locking teeth 68 are provided on the edge of the rotating ring 63. A locking pin 65 is provided at the upper end of the fixing groove 62. A first locking rod 66 and a second locking rod 69 are rotatably connected to the upper end of the fixing groove 62 and located on both sides of the locking pin 65. The end of the first locking rod 66 and the end of the second locking rod 69 are aligned with the locking teeth 68 of the rotating ring 63. The upper end of the fixed groove 62 and located on one side of the first locking rod 66 and one side of the second locking rod 69 are both provided with a telescopic spring 67. The telescopic spring 67 is used to push the first locking rod 66 and the second locking rod 69 to rotate. The locking pin 65 is used to push the first locking rod 66 and the second locking rod 69 to rotate. When the rotating pin 412 rotates, it drives the rotating ring 63 to rotate. The first locking rod 66 and the second locking rod 69 are used to control the forward and reverse rotation or stop of the rotating ring 63. The locking pin 65 is adjusted to push the first locking rod 66 or the second locking rod 69 away from the locking pin 65, so that the first locking rod 66 or the second locking rod 69 is away from the locking pin 65, thereby controlling whether the first locking rod 66 or the second locking rod 69 is engaged with the locking teeth 68 of the rotating ring 63.

[0046] See also Figure 9 As shown, the locking pin 65 rotates against the first locking rod 66, the end of the first locking rod 66 is separated from the locking tooth 68, and the end of the second locking rod 69 is engaged with the locking tooth 68. The fixed block 49 and the rotating circle 63 only rotate clockwise, and the locking pin 65 presses against the first locking rod 66 so that the first locking rod 66 is separated from the locking tooth 68, and the second locking rod 69 is engaged with the locking tooth 68. At this time, the locking tooth 68 of the rotating circle 63 can rotate clockwise. When rotating in the opposite direction, the locking tooth 68 of the rotating circle 63 presses against the second locking rod 69, and the rotating circle 63 and the rotating pin 412 cannot rotate counterclockwise.

[0047] See also Figure 10As shown, the locking pin 65 is separated from the first locking rod 66 and the second locking rod 69, and the end of the first locking rod 66 and the end of the second locking rod 69 are both engaged with the locking teeth 68, the fixed block 49 and the rotating circle 63 stop rotating, and the locking pin 65 is not in contact with the first locking rod 66 and the second locking rod 69. At this time, the first locking rod 66 and the second locking rod 69 are both engaged with the locking teeth 68 of the rotating circle 63, so that the rotating circle 63 and the rotating pin 412 cannot rotate, thereby restricting the rotation of the fixed block 49 and the drill bit 48.

[0048] See also Figure 11 As shown, the locking pin 65 rotates against the second locking rod 69, the end of the second locking rod 69 is separated from the locking tooth 68, and the end of the first locking rod 66 is engaged with the locking tooth 68. The fixed block 49 and the rotating circle 63 only rotate counterclockwise, and the locking pin 65 presses against the second locking rod 69 so that the second locking rod 69 is separated from the locking tooth 68, and the first locking rod 66 is engaged with the locking tooth 68. At this time, the locking tooth 68 of the rotating circle 63 can rotate counterclockwise. When rotating in the reverse direction, the locking tooth 68 of the rotating circle 63 presses against the first locking rod 66, and the rotating circle 63 and the rotating pin 412 cannot rotate clockwise.

[0049] It should be noted that when the drill bit 48 is parallel to the axis of the drill rod 2 or when the drill bit 48 is inclined to the axis of the drill rod 2, the locking pin 65 can be placed in an intermediate state, so that the first locking rod 66 and the second locking rod 69 are both engaged with the locking teeth 68 of the rotating ring 63, and the drill bit 48 and the fixed block 49 will not rotate. When it is necessary to adjust the rotation of the drill bit 48 and the fixed block 49, the locking pin 65 can be pressed against the first locking rod 66 or the second locking rod 69, so that the end of the first locking rod 66 or the end of the second locking rod 69 is engaged with the locking teeth 68 of the rotating ring 63, and the locking teeth 68 of the rotating ring 63 can be rotated in one direction, and the drill bit 48 and the fixed block 49 can be rotated clockwise or counterclockwise around the rotating pin 412.
