Description

Technical Field

[0001] The present invention relates to the technical field of mineral extraction, and specifically relates to a rock drilling guiding device for metal mineral extraction. Background Art

[0002] When extracting minerals, it is necessary to use a rock drilling device to make holes in the ore for facilitating the installation of equipment such as anchor rods, pipelines, and cables in the later stage. The rock drilling device generally uses a tool that is harder and sharper than the rock to leave a cylindrical hole or cavity on the target object by means of rotary cutting or rotary extrusion. Since the drill bit of the rock drilling device is rigidly blocked from descending when encountering relatively hard rock during the downward feeding process, it may cause the drill pipe transmission mechanism to suddenly stop, resulting in poor equipment stability and easy vibration, which affects the rock drilling effect.

[0003] To solve the above technical problems, the utility model patent with the publication number CN219061531U in the prior art discloses a guiding device for rock drilling. When the drill bit vibrates, it presses the laminated plate outward, and under the elastic buffering and restoring action of the damping spring assembly, the column platform placed inside is horizontally limited by the positioning insertion rod to achieve parallel guiding sliding between the column platform and the guiding plate, avoiding the problem of drill bit vibration.

[0004] In practical applications, the direction of mine drilling depends on specific mining requirements and geological conditions. In addition to vertical drilling, there is also an inclined drilling method. The drilling method of the existing technology's drilling rig is vertical downward drilling, which is only applicable to buffering horizontal vibrations during vertical downward drilling. In the case of inclined drilling of rocks, the drill bit generally easily undergoes rigid collision with the rock and vibrates in its own vertical direction. The prior art cannot achieve anti-vibration in the vertical direction of the drilling rig body during inclined drilling. Summary of the Invention

Detailed implementation manners

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the present invention provides a rock drilling guiding device for metal ore mining, including a carriage 1 and a drill rig 9 movable along the carriage 1.

[0052] An activity cylinder cabin 29 is movably installed outside the drill rig 8. The activity cylinder cabin 29 can move forward along the drill rig 8. A number of limiting plates 16 are installed in a circular array outside the activity cylinder cabin 29. An airbag 17 is installed between the outer wall of the activity cylinder cabin 29 and each limiting plate 16. The airbag 17 is externally connected to an air driving structure 33. The air driving structure 33 controls the inflation and deflation of the airbag 17, so that the airbag 17 expands or contracts. When the airbag 17 expands, the limiting plate 16 extends outward;

[0053] An adjustment driving structure is installed on the drill rig 9. A drill bit 14 is arranged on the adjustment driving structure. The adjustment driving structure can adjust the drilling position of the drill bit 14 in a direction perpendicular to the drill bit 14 and drive the drill bit 14 to rotate;

[0054] A propulsion structure is arranged on the carriage 1. The propulsion structure 10 pushes the drill rig 9 to advance forward along the carriage 1 and drives the drill bit 14 to advance forward for drilling;

[0055] A pre-installation hole is drilled on the surface to be drilled by the drill bit 14. The drill rig 9 drives the activity cylinder cabin 29 into the pre-installation hole under the pushing action. The limiting plate 16 extends outward and supports on the inner wall of the pre-installation hole. The drill rig 9 advances forward along the activity cylinder cabin 29 under the pushing action and drives the drill bit 14 to continue to drill deeper.

[0056] A slide rail 2 is formed on the carriage 1. An installation frame 3 is installed on the side of the carriage 1. The carriage 1 is rotatably installed on the installation frame 3. The carriage 1 can rotate around the installation frame 3. A propulsion platform 7 is slidably installed on the slide rail 2. The bottom of the propulsion platform 7 is connected to the drill rig 9 through a connecting rod 8. A propulsion structure 10 connected to the propulsion platform 7 is installed on the carriage 9. The propulsion structure 10 can push the propulsion platform 7 to slide along the slide rail 2 to realize the propulsion of the drill rig 9.

[0057] In the present invention, the adjustment drive structure includes a first U-shaped frame 4 fixed to the bottom of the drill rig. The first U-shaped frame 4 is fixed to the bottom of the drill rig 9. The drill rig 9 is installed downward with a motor 11. A drive shaft 12 is provided at the bottom of the motor 11. The drive shaft 12 penetrates through the first U-shaped frame 4. A second U-shaped frame 5 is rotatably installed in the first U-shaped frame 4.

[0058] The transmission assembly 6 is installed in the second U-shaped frame 5. The input end of the transmission assembly 6 is connected to the drive shaft 12, and its output end is connected to a transmission shaft 13. A drill bit 14 is installed at the bottom end of the transmission shaft 13. A sliding seat 15 is slidably arranged at the bottom of the second U-shaped frame 5. The transmission shaft 13 is installed on the sliding seat 15 and moves along the length direction of the second U-shaped frame 5 following the sliding seat 15. The drive shaft 12 can drive the transmission shaft 13 at different positions to rotate through the transmission assembly 6.

[0059] No matter which position the sliding seat 15 drives the transmission shaft 13 to move to, the transmission assembly 6 plays the role of transmitting between the drive shaft 12 and the transmission shaft 13.

[0060] Among them, the second U-shaped frame 5 is mainly a structure for installing the transmission assembly 6, and the second U-shaped frame 5 can drive the drill bit 14 to rotate around the drive shaft 12 as the central axis. Assuming that the drive shaft 12 and the drill bit 14 are coaxial, the above rotation action will only drive the drill bit 14 to rotate around itself. When the drill bit 14 moves to a position where it is not coaxial with the drive shaft 12, the above rotation action will drive the drill bit 14 to rotate around the drive shaft 12. This rotation action can adjust the position of the drill bit 14 on the circumference at its position, so as to realize the adjustment of the drilling position in the circumferential direction.

[0061] The movable cylinder cabin 29 is movably installed outside the drill rig 9. A limiting plate 16 is installed outside the movable cylinder cabin 29. An airbag 17 is arranged between the limiting plate 16 and the drill rig 9. The airbag 17 is regarded as a buffer structure. An air injection pipe 18 is externally connected to the movable cylinder cabin 29 and penetrates through the inner wall of the movable cylinder cabin 29 and communicates with the inside of the airbag 17. The airbag 17 is inflated by injecting air to drive the limiting plate 16 to expand outward and adhere to the inner wall of the pre-installed hole that has been drilled.

[0062] By inflating the inside of the airbag 17, not only can the airbag 17 be inflated to drive the limiting plate 16 to expand outwards and be fixed within the hole wall, but also the inflation degree of the airbag 17 itself can be adjusted, thereby realizing the adjustment of the buffering effect of the airbag 17 itself. The larger the inflation degree of the airbag 17, the smaller the bufferable space, and the worse the buffering effect; the smaller the inflation degree, the larger the bufferable space, and the better the buffering effect. However, in the actual application process, the inflation degree of the airbag 17 is also affected by the limiting plate 16. After the limiting plate 16 is attached and fixed to the inner wall of the hole wall, it cannot expand outwards anymore. After the airbag 17 is inflated, it expands vertically. The airbag 17 itself is made of a stretchable rubber-like material. When the airbag 17 expands to a certain extent, a buffer space cannot be formed anymore. Therefore, it is necessary to control the inflation degree of the airbag 17 to avoid poor buffering effect.

[0063] In the present invention, the drill bit 14 can not only adjust the drilling position along the circumferential direction, but also adjust the drilling position along the radial direction. Taking the drive shaft 12 as the central axis, the drill bit 14 can be driven by the sliding seat 15 to adjust the drilling position along the radial direction, and can be driven by the rotation of the second U-shaped frame 5 to adjust the drilling position along the circumferential direction. Generally speaking, the cooperation of the drilling adjustments in the two directions can realize the adjustment of the drill bit 14 to any drilling position within a certain range in the plane.

[0064] In the present invention, an activity cylinder cabin 29 is arranged outside the drill rig 9, and a limiting plate 16 is installed outside the activity cylinder cabin 29. An airbag 17 is arranged between the limiting plate 16 and the activity cylinder cabin 29, and the buffering effect between the limiting plate 16 and the activity cylinder cabin 29 is formed by the airbag 17. When the drill bit 14 has a rigid collision with the rock and shakes, under the buffering action of the airbag 17, the whole drill rig 9 is limited in the direction perpendicular to the drill rig 9, so as to avoid the problems of the overall structure shaking and the drilling direction deviation caused by the shaking of the drill rig 9 itself.

[0065] In addition, the sliding seat 15 can drive the drill bit 14 to adjust the drilling position along the radial direction. On the one hand, it can realize the fine adjustment of the drilling position. On the other hand, by adjusting the drilling position along the radial direction and cooperating with the rotation action to perform the drilling process multiple times, a drilling action with a larger radius can be realized to drill a pre-installation hole. The activity cylinder cabin 29 is positioned within the pre-installation hole by inflating the airbag 17, so as to realize the buffering between the hole wall and the drill rig 9, and further weaken the linkage shaking effect between the drill rig 9, the propulsion platform 7 and the sliding frame 1, and weaken the influence of the shaking action.

[0066] In the present invention, the drill bit 14 basically does not generate a shaking linkage action on the propulsion platform 7 during operation. For this, the present invention makes the following design, as Figure 5 and Figure 6 shown, a force application groove 19 is opened at the top of the drill rig 9; the bottom of the connecting rod 8 is connected with a connecting seat 20, and the connecting seat 20 is arranged within the force application groove 19;

[0067] Among them, the width of the connecting seat 20 is smaller than the width inside the force - applying groove 19, and the height of the connecting seat 20 is smaller than the depth of the force - applying groove 19, and the width of the connecting rod 8 is smaller than the width of the opening of the force - applying groove 19.

[0068] Under the action of gravity, the drill rig 9 must be at the bottommost part of the connecting rod 8, and the connecting seat 20 is at the opening part inside the force - applying groove 19. Due to the limitation of size, the connecting rod 8 and the drill rig 9 cannot be separated, and there is no connection relationship between the connecting rod 8 and the drill rig 9, and the end of the connecting rod 8 can move inside the force - applying groove 19.

[0069] During the process of drilling the pre - installation hole, under the supporting action of the rock at the bottom of the drill rig 9, the connecting seat 20 gradually moves to the inner bottom of the force - applying groove 19 and drives the drill rig 9 to move downward through the force - applying groove 19.

[0070] In the present invention, the pre - installation hole is generally larger than the rock hole to be drilled. The pre - installation hole is used to install the limit plate 16, converting the linkage effect of the shaking of the drill rig 9 driving the overall shaking of the machine into the linkage between the drill rig 9 and the limit plate 16. The shaking of the drill rig 9 in its own vertical direction (transverse) will drive the air bag 17 to shake, and the air bag realizes the buffering of the shaking action between the drill rig 9 and the limit plate 16.

[0071] In addition, the shaking of the drill rig 9 in its own vertical direction will not drive the connecting rod 8 to shake, which avoids the overall shaking of the structure caused by the shaking of the drill rig 9.

[0072] In the present invention, both the first U - shaped frame 4 and the second U - shaped frame 5 are arranged vertically, and the openings are opposite to each other.

[0073] In the present invention, as Figure 7 、 Figure 8 shown, the transmission component 6 realizes the transmission connection between the transmission shaft 13 and the driving shaft 12. The transmission component 6 adopts the following preferred embodiment. The transmission component 6 includes a first transmission disk 61, a second transmission disk 62, and a third transmission disk 63 that are installed in sequence from top to bottom and have the same radius. The center position of the first transmission disk 61 is connected to the bottom of the driving shaft 12, and the circular position of the third transmission disk 63 is connected to the top of the transmission shaft 13;

[0074] The first transmission disk 61 and the second transmission disk 63 are connected by a number of first transmission plates 64. The directions of the first transmission plates 64 are all the same. The first transmission plates 64 are rotatably installed on the first transmission disk 61 through the first connecting shaft 65 and rotatably installed on the second transmission disk 62 through the second connecting shaft 66;

[0075] The second drive disk 62 and the third drive disk 63 are connected by a number of second drive plates 67. The directions of the second drive plates 67 are all the same. The second drive plates 67 are rotatably mounted on the second drive disk 62 through the third connecting shafts 68 and are mounted on the third drive disk 63 through the fourth connecting shafts 69.

[0076] The first drive disk 61 can drive the second drive disk 62 to rotate through the first drive plate 64. The second drive disk 62 can drive the third drive disk 63 to rotate through the second drive plates 67, thereby driving the transmission shaft 13 to rotate.

[0077] As Figure 9 shown, in the initial state, the drill bit 14 is coaxial with the drive shaft 12, and the transmission shaft 13 is coaxial with the drive shaft 12. Driven by the sliding seat 15, the third drive disk 63 moves along the length direction of the second U-shaped frame 5. As Figure 10 shown, during this process, under the extrusion of the second drive plates 67, an extrusion force will be generated on the second drive disk 62, causing the second drive disk 62 to move along a direction perpendicular to the movement direction of the third drive disk 63. During this process, the distance between the central axes of the third drive disk 63 and the second drive disk 62 always remains unchanged, and the distance between the central axes of the first drive disk 61 and the second drive disk 62 also remains unchanged, and the first drive disk 61, the second drive disk 62, and the third drive disk 63 always maintain a synchronous rotation transmission relationship.

[0078] In the present invention, the second U-shaped frame 5 can rotate within the first U-shaped frame 4 to drive the sliding seat 15 that has been adjusted radially to rotate. To drive the rotation of the second U-shaped frame 5, the present invention makes the following design. As Figure 8 shown, a ring seat 21 is installed at the top end of the second U-shaped frame 5. A toothed groove is provided on the outer peripheral side of the ring seat 21. An annular mounting seat 22 is installed at the bottom of the first U-shaped frame 5. The top of the ring seat 21 extends into the annular mounting seat 22 and can rotate inside the annular mounting seat 22;

[0079] Among them, the drive shaft 12 passes through the ring seat 21 and the annular mounting seat 22.

[0080] A notch 23 is provided on the side of the annular mounting seat 21, and at least part of the outer periphery of the ring seat 21 extends outside the notch 23;

[0081] A first drive motor 24 is provided inside the first U-shaped frame 4. The bottom end of the first drive motor 24 is connected with a drive gear 25. The drive gear 25 meshes with the toothed groove and drives the ring seat 21 to rotate.

[0082] The first drive motor 24 drives the drive gear 25 to rotate, thereby driving the ring seat 21 to rotate and driving the second U-shaped frame 5 to rotate. During the rotation of the second U-shaped frame 5, the sliding seat 15 and the transmission shaft 13 move accordingly.

[0083] In the present invention, to drive the sliding seat 15 to slide, the following design is made in the present invention, as Figure 8 shown, a sliding groove 26 for the sliding seat 15 to slide is provided in the second U-shaped frame 5. Driving cylinders 27 are installed on both sides inside the sliding groove 26. The output end of the driving cylinder 27 is connected with a push rod 28, and the push rod 28 penetrates through the inner wall of the sliding groove 26 and faces the side of the sliding seat 15.

[0084] The driving cylinder 27 drives the push rod 28 to apply a thrust to the sliding seat 15, and the position of the sliding seat 15 in the sliding groove 26 can be controlled by controlling the lengths of the two push rods 28.

[0085] In the present invention, the transmission assembly 6 can also reduce the jitter of the drill bit 14 in a certain direction. Assuming that the drill bit 14 jitters along the direction of the sliding groove 26, it will cause the positions of the third transmission disc 63 and the second transmission disc 62 to change. The first transmission disc 61, the second transmission disc 62, and the third transmission disc 63 always maintain a synchronous rotation transmission relationship. The transmission assembly 6 will only change its own position within a small range in the case of jitter, and will not directly conduct the jitter to the drive shaft 12 to achieve anti-jitter along the direction of the sliding groove 26.

[0086] In the present invention, after the height position of the movable cylinder chamber 29 relative to the limiting plate 16 is fixed and cannot be lowered anymore, at this time, if the operation of lowering and drilling is still required, the following design is made in the present invention. Skid plates 30 are symmetrically installed inside the movable cylinder chamber 29 at positions facing the drill rig 9. A connecting plate 31 is installed outside the drill rig 9, and the connecting plate 31 is slidably arranged between the two skid plates 30. The bottom of the skid plate 30 is closed, and a spring is provided between the connecting plate 31 and the closed bottom of the skid plate 30.

[0087] After the movable cylinder chamber 29 follows the limiting plate 16 and is fixed at a specific height in the pre-installed hole, the pushing platform 7 is further pushed, and the drill rig 9 is pushed down through the connecting rod 8. During this process, the connecting plate 31 slides between the skid plates 30, the spring is gradually compressed, and the drill rig 9 is pushed down to drive the drill bit 14 to move down for drilling.

[0088] To realize the telescopic adjustment of the airbag 17 itself, the following design is made in the present invention, as Figure 2 and Figure 3 shown, an air vent pipe 32 is provided in the movable cylinder chamber 29. The air vent pipe 32 communicates with the airbag 17 and the air injection pipe 18.

[0089] In the above embodiments, the air driving structure 3 can be externally connected to a gas source, and an air pump can be arranged inside the air driving structure 3. The gas source is pumped into the air injection pipe 18 and filled into the airbag 17 through the air pump.

[0090] In the present invention, the propulsion structure 10 can achieve the propulsion of the propulsion platform 7 and the drill rig 9. The propulsion structure 10 adopts the following preferred embodiment. The propulsion structure 10 includes a propulsion cylinder and a chain 101 installed in the carriage 1;

[0091] The output end of the propulsion cylinder is connected to the propulsion platform 7, and the end of the chain 101 is connected to the propulsion platform 7. A bearing bracket 102 is installed on the back of the carriage 7, and the end of the chain 101 is wound around the bearing bracket 102. The chain 101 extends outward from the bearing bracket 102 when the propulsion platform 7 moves along the slide rail 2.

[0092] The propulsion cylinder can push the propulsion platform 7 forward. During the forward movement, the chain 101 is gradually stretched.

[0093] In the present invention, the carriage 1 can rotate to adjust its own angle, so as to adjust the overall forward angle of the drill rig 9 and the drilling angle. For this purpose, the present invention makes the following design. A hydraulic cylinder 34 is installed on the mounting frame 3, and the output end of the hydraulic cylinder 34 is connected to the side wall of the carriage 1. By driving the hydraulic cylinder 34 to push the side wall of the drill rig 9, the angle of the drill rig 9 is adjusted accordingly.

[0094] The mounting frame 3 is fixedly installed on the traveling structure or the fixed platform 35, and the traveling structure can be a crawler vehicle or the like.

[0095] In the present invention, the drill bit 14 can be set as a detachable threaded connection, so as to replace drill bits 14 with different diameters in different application scenarios.

[0096] In summary, the main implementation process of the present invention is as follows:

[0097] Preset the drilling angle, and adjust the angle of the drill rig 9 by driving the hydraulic cylinder 34, and adjust the position of the mounting frame 3 so that the drill rig 9 faces the position to be drilled;

[0098] First, install the large-diameter drill bit 14 on the transmission shaft 13, and push the propulsion platform 7 to move forward along the direction of the slide rail 2 through the propulsion structure 10, and drive the drill rig 9 to gradually move forward through the connecting rod 20;

[0099] The motor 11 drives the drive shaft 12 to rotate, and drives the transmission shaft 13 to rotate through the transmission assembly 6. The drill bit 14 rotates and moves forward to achieve drilling and obtain a pre-installation hole;

[0100] Assume that the diameter of the pre-installation hole obtained by single drilling is not sufficient to install the limit plate 16 and the movable cylinder compartment 29. Then, adjust the position of the sliding seat 15 by driving the cylinder 27 and adjust the position of the drill rod 14 by driving the first driving motor 24 to drive the second U-shaped frame 5 to rotate, so as to be able to install the limit plate 16 as the standard. Adjust the position multiple times and perform the drilling action to obtain a pre-installation hole with a larger diameter;

[0101] Inflate the inside of the airbag 17, and the airbag 17 is inflated to drive the limit plate 16 to expand outward and adhere to the inner wall of the pre-drilled pre-installation hole;

[0102] The height position of the movable cylinder chamber 29 in the pre-installation hole is fixed. Then, the propulsion structure 10 continues to advance on the basis of the original propulsion position, and the drill rig 9 is pushed forward by the connecting rod 8. The drill rig 9 moves forward relative to the movable cylinder chamber 29 to realize drilling of deeper rocks.
