Description

Technical Field

[0001] The utility model belongs to the technical field of drill bits, and in particular relates to a laser drill bit with adjustable light beam trajectory. Background Art

[0002] Laser drilling is an innovative drilling technology. The laser component installed on the drill bit first uses the laser component to illuminate the rock surface before breaking the rock through the drill bit, destroying the rock surface structure. The drill bit is then used to drill. Compared with the traditional drilling method using only the drill bit, it can improve drilling efficiency.

[0003] Laser components usually include a laser, a laser head and a lens. The laser is used to generate laser light. The laser head receives the laser light generated by the laser and shoots the laser light toward the lens. After being focused by the lens, the laser light is focused and accurately shot toward the rock surface.

[0004] In order to ensure the focusing effect of the laser, the position of the lens relative to the laser head needs to be adjusted. Therefore, a moving component needs to be set on the drill bit to move the lens. Although common moving components such as hydraulic cylinders or electric push rods can move the lens, these moving components have complex structures and large sizes, making them inconvenient to install on the drill bit.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

Therefore, they should not be understood as limitations on the present invention.

[0026] An embodiment of the present application provides a laser drill with an adjustable beam trajectory, comprising a drill body 1, a laser component, and a moving component 4. The drill body 1 is provided with a through hole along the axial direction of the drill body 1. The laser component includes a lens 2, and the lens 2 is provided in the through hole. The moving component 4 includes a pressure-applying portion 11 and a pushing portion 12. The pressure-applying portion 11 is movably connected to the drill body 1 along the axial direction of the drill body 1, and the pushing portion 12 is movably provided on the drill body 1 along a direction perpendicular to the axial direction of the through hole. The pushing portion 12 includes a first inclined surface, and the pressure-applying portion 11 abuts against the first inclined surface to push the pushing portion 12 to move. The pushing portion 12 also includes a second inclined surface, and the lens 2 abuts against the second inclined surface so that the pushing portion 12 pushes the lens 2 to move along the axial direction of the through hole.

[0027] The drill bit body 1 is a component used for drilling holes in rocks. Generally speaking, when the drill bit body 1 is working, the drill bit body 1 is connected to the drill rod, and the power of the drill rod is transmitted to the drill bit body 1, so that the drill bit body 1 can rotate.

[0028] The through hole is used to install the lens 2 on one hand, and on the other hand enables the laser to be emitted from the through hole and illuminate the rock surface.

[0029] The lens 2 is disposed in the through hole so that the lens 2 can be slidably connected to the drill body 1 , that is, the lens 2 can move along the axial direction of the through hole.

[0030] When the pressure-applying portion 11 moves, the pressure-applying portion 11 generates a force on the first inclined surface, thereby enabling the pushing portion 12 to move in a direction perpendicular to the axial direction of the through hole. When the pushing portion 12 moves, under the action of the second inclined surface, the lens 2 can move along the axial direction of the through hole, thereby enabling the position of the lens 2 relative to the laser head 3 to be adjusted.

[0031] Compared with the traditional moving component 4, the laser head 3 is moved by cooperating with the pressure-applying portion 11 and the pushing portion 12, which has a simple and reliable structure, occupies a small space, and is suitable for use in high-temperature environments.

[0032] The driving device of the pressure applying portion 11 can be selected from existing structures.

[0033] The pressure-applying part 11 is movably arranged on the drill body 1 along the axial direction of the drill body 1, so that the driving device of the pressure-applying part 11 can be arranged on one axial side of the drill body 1. On the one hand, it will not hinder the drilling work of the drill body 1. On the other hand, the driving device of the pressure-applying part 11 can be arranged outside the drill body 1, without the need to improve the structure of the drill body 1, thereby reducing the installation space occupied by the drill body 1.

[0034] In some embodiments, the drill body 1 is provided with an accommodating cavity 10 , the accommodating cavity 10 is communicated with the peripheral wall of the through hole, and the pushing portion 12 is provided in the accommodating cavity 10 .

[0035] The accommodating cavity 10 is connected to the through hole, so that when the lens 2 is located in the middle of the through hole, the lens 2 can still be pushed to move by the pushing portion 12 .

[0036] The inner wall surface of the accommodating cavity 10 may be provided with a limiting portion, which abuts against the pushing portion 12 , so that the pushing portion 12 can be movably disposed in the accommodating cavity 10 along a direction perpendicular to the axial direction of the through hole.

[0037] In some embodiments, the drill bit body 1 includes a first side 9 for connecting to a drill rod. The drill bit body 1 is provided with a sliding hole 15 . The pressure applying portion 11 is passed through the sliding hole 15 . The sliding hole 15 passes through the first side 9 .

[0038] The pressure applying portion 11 is inserted into the sliding hole 15 , so that the pressure applying portion 11 can move relative to the drill body 1 .

[0039] The slide hole 15 extends through the first side 9, allowing the pressure-applying portion 11 to be partially disposed outside the drill body 1, facilitating movement of the pressure-applying portion 11 by a driving device disposed outside the drill body 1. For example, a hydraulic cylinder may be disposed outside the drill body 1, with the telescopic end of the hydraulic cylinder connected to the pressure-applying portion 11, allowing the hydraulic cylinder to drive the pressure-applying portion 11 to move.

[0040] In some embodiments, the moving component 4 further includes a first elastic member 13 , which connects the lens 2 and the drill body 1 .

[0041] The first elastic member 13 may be a spring, and the first elastic member 13 connects the lens 2 and the drill body 1, so that the lens 2 can be kept against the second inclined surface, thereby improving the accuracy of the movement of the lens 2 driven by the pushing portion 12. Furthermore, the moving component 4 may also include a second elastic member 14, which may be a spring. The second elastic member 14 connects the pushing portion 12 and the drill body 1, so that the first inclined surface can be kept against the pressure portion 11, thereby improving the accuracy of the pressure portion 11 pushing the pushing portion 12 to move.

[0042] In some embodiments, the drill bit body 1 includes a first side 9 for connecting to a drill rod, the through hole includes a first hole section 7 and a second hole section 6, the aperture of the first hole section 7 is larger than the aperture of the second hole section 6, the first hole section 7 is close to the first side 9, and the laser component also includes a laser head 3, the laser head 3 is accommodated in the first hole section 7, and the lens 2 is accommodated in the second hole section 6.

[0043] The operating principle of the laser component is well known to those skilled in the art. In summary, when the laser component is operating, the laser light generated by the laser is transmitted via an optical fiber to the laser head 3. The laser light emitted by the laser head 3 is focused by the lens 2 and then emitted toward the rock surface. The principle of laser destruction of rock surfaces is well known to those skilled in the art and will not be further elaborated here.

[0044] The aperture of the first hole segment 7 is larger than that of the second hole segment 6. On the one hand, the laser head 3 of common laser components is often larger than the lens 2. The larger aperture of the first hole segment 7 than that of the second hole segment 6 allows the aperture of the first hole segment 7 to be adapted to the size of the laser head 3, allowing the laser head 3 to be installed in the through-hole. On the other hand, the larger aperture of the first hole segment 7 than that of the second hole segment 6 allows a transition surface to be formed between the first hole segment 7 and the second hole segment 6. The laser head 3 abuts against the transition surface, thereby fixing the relative position of the laser head 3 and the lens 2. On the other hand, the second hole segment 6 is used to adapt to the lens 2, allowing the lens 2 to be slidably connected to the drill body 1, thereby increasing the movement accuracy of the lens 2 relative to the through-hole.

[0045] In some embodiments, the through hole further includes a third hole segment 8 , which is disposed on a side of the first hole segment 7 close to the first side 9 , the aperture of the third hole segment 8 is larger than the aperture of the first hole segment 7 , and the laser head 3 is partially disposed in the third hole segment 8 .

[0046] The aperture of the third hole segment 8 is larger than that of the first hole segment 7 , which, on the one hand, increases the operating space and facilitates the disassembly and assembly of the laser head 3 , and on the other hand, can increase the heat dissipation effect of the laser head 3 .

[0047] In some embodiments, the drill body 1 is further provided with a fixing component 5 , the fixing component 5 is threadedly connected to the third hole section 8 , and the laser head 3 is threadedly connected to the fixing component 5 .

[0048] The outer circumferential wall of the fixing component 5 may be provided with threads, and the inner circumferential wall of the third hole section 8 may also be provided with threads, so that the fixing component 5 and the third hole section 8 can be threadedly connected.

[0049] The fixing component 5 and the third hole section 8 are connected by threads so that the two can be detachably connected, which facilitates the disassembly and assembly of the laser head 3 .

[0050] The laser head 3 and the fixing component 5 are threadedly connected. On the one hand, the laser head 3 is arranged on the fixing component 5 to facilitate the installation of the laser head 3. On the other hand, the position of the laser head 3 relative to the fixing component 5 can be adjusted, so that the position of the laser head 3 in the second through hole can be adjusted after the installation is completed.

[0051] In some embodiments, the fixing member 5 includes an outer ring body 18, an inner ring body 16, and a connecting wall 17. The outer ring body 18 is threadedly connected to the third hole segment 8. The outer ring body 18 is sleeved outside the peripheral wall of the inner ring body 16, and the laser head 3 is inserted into the inner ring body 16. The connecting wall 17 connects the outer ring body 18 and the side of the inner ring body 16 away from the first hole segment 7.

[0052] The inner ring body 16 can be threadedly connected to the laser head 3 .

[0053] The connecting wall 17 connects the inner ring body 16 and the outer ring body 18 on one side away from the first hole section 7. On the one hand, the inner ring body 16 and the outer ring body 18 are hollow, which reduces the weight of the fixed component 5. On the other hand, an installation space can be formed between the inner ring body 16 and the outer ring body 18 for installing other components.

[0054] In some embodiments, the fixing component 5 further includes a cooling medium channel 21 , and the cooling medium channel 21 is disposed around the outer peripheral wall of the inner ring body 16 .

[0055] The cooling medium channel 21 is used to pass the cooling medium, and the heat generated by the laser head 3 is transferred to the inner ring. Therefore, by cooling the inner ring body 16, the laser head 3 can be cooled to ensure that the laser head 3 is in a suitable working environment.

[0056] In some embodiments, a cooling medium cavity may be further included. Both ends of the cooling medium channel 21 are respectively connected to the cooling medium cavity. The cooling medium cavity contains cooling medium so that the cooling medium can circulate in the cooling medium channel 21 .

[0057] In some embodiments, the connecting wall 17 may be provided with a through hole 19 for allowing the cooling medium channel 21 to pass through and out between the inner ring body 16 and the outer ring body 18 .

[0058] In some embodiments, a groove 20 is provided on the outer peripheral wall of the inner ring body 16 . The groove 20 extends spirally along the axis of the inner ring body 16 , and the cooling medium channel 21 is accommodated in the groove 20 .

[0059] The recess is used to fix the cooling medium channel 21 , and the cooling medium channel 21 is accommodated in the groove 20 , thereby increasing the connection reliability between the cooling medium channel 21 and the inner ring body 16 .

[0060] The groove 20 extends in a spiral shape, which increases the contact area between the cooling medium channel 21 and the inner ring body 16 , thereby increasing the cooling effect on the inner ring body 16 .

[0061] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various deformations, modifications, alterations, and substitutions of the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
