Description

Technical Field

[0001] This invention relates to the field of mineral mining technology, and more specifically to a rock drilling guide device for metal mining. Background Technology

[0002] When mining minerals, rock drilling equipment is needed to drill holes in the ore to facilitate the later installation of equipment such as anchor bolts, pipes, and cables. Rock drilling equipment generally uses tools that are harder and sharper than the rock to leave cylindrical holes or cavities in the target object through rotary cutting or rotary extrusion. Because the drill bit of the rock drilling equipment will rigidly stop the drill bit when it encounters relatively hard rock during the downward feeding process, it may cause the drill rod transmission mechanism to stop suddenly. The equipment has poor stability and is prone to vibration, which affects the rock drilling effect.

[0003] To solve the above-mentioned technical problems, the prior art utility model patent with publication number CN219061531U discloses a guiding device for rock drilling. When the drill bit vibrates, the stacked plate is pressed outward. Under the elastic buffering and recovery action of the damping spring assembly, the column placed on the inner side is laterally limited by the positioning rod, so as to realize the parallel guiding sliding of the column and the guide plate and avoid the problem of drill bit vibration.

[0004] In practical applications, the direction of drilling in mines depends on specific mining needs and geological conditions. In addition to vertical drilling, there is also inclined drilling. Existing drilling rigs use vertical drilling, which is only suitable for buffering horizontal vibrations during vertical drilling. When inclined drilling is required, the drill bit is prone to rigid collision with the rock, causing vibrations in its vertical direction. Existing technology cannot prevent vibrations in the vertical direction of the drilling rig body during inclined drilling. Summary of the Invention

[0005] Therefore, the present invention provides a rock drilling guide device for metal mining, which effectively solves the technical problem that the existing technology cannot achieve anti-shaking in the vertical direction of the drilling rig body during inclined drilling.

[0018] The center of the first transmission disc is connected to the bottom of the drive shaft, and the circular position of the third transmission disc is connected to the top of the drive shaft;

[0023] The annular mounting base has a notch on its side, and at least a portion of the outer periphery of the annular base extends beyond the notch;

[0024] The first U-shaped frame is equipped with a first drive motor, and the bottom end of the first drive motor is connected to a drive gear. The drive gear meshes with the tooth groove and drives the ring seat to rotate.

[0025] Furthermore, the second U-shaped frame has a sliding groove for the sliding seat to slide in. A drive cylinder is installed on both sides of the sliding groove.

Detailed Implementation

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a rock drilling guide device for metal mining, including a slide 1 and a drill frame 9 that moves along the slide 1.

[0052] A movable chamber 29 is movably installed outside the drill frame 8. The movable chamber 29 can move forward along the drill frame 8. Several limiting plates 16 are arranged in a circular pattern outside the movable chamber 29. An airbag 17 is installed between the outer wall of the movable chamber 29 and each limiting plate 16. An air drive structure 33 is connected to the airbag 17. The air drive structure 33 controls the inflation and deflation of the airbag 17, causing the airbag 17 to expand or contract. When the airbag 17 expands, the limiting plate 16 extends outward.

[0053] An adjustment drive structure is installed on the drill frame 9, and a drill bit 14 is provided on the adjustment drive structure. The adjustment drive structure can adjust the drilling position of the drill bit 14 and drive the drill bit 14 to rotate in a direction perpendicular to the drill bit 14.

[0054] A propulsion structure is provided on the slide 1. The propulsion structure 10 pushes the drill frame 9 forward along the direction of the slide 1 and drives the drill bit 14 forward to drill a hole.

[0055] The drill bit 14 drills a pre-installation hole on the surface to be drilled. The drill frame 9 is pushed to move the movable chamber 29 into the pre-installation hole. The limiting plate 16 extends outward and supports the inner wall of the pre-installation hole. The drill frame 9 is pushed forward along the movable chamber 29 and drives the drill bit 14 to continue drilling deeper.

[0056] A slide rail 2 is formed on the slide 1, and a mounting frame 3 is installed on the side of the slide 1. The slide 1 is rotatably mounted on the mounting frame 3 and can rotate around the mounting frame 3. A propulsion platform 7 is slidably mounted on the slide rail 2. A drill frame 9 is connected to the bottom of the propulsion platform 7 through a connecting rod 8. A propulsion structure 10 connected to the propulsion platform 7 is installed on the slide 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 frame 9.

[0057] In this invention, the adjustment drive structure includes a first U-shaped frame 4 fixed to the bottom of the drill frame 9. The first U-shaped frame 4 is fixed to the bottom of the drill frame 9. The drill frame 9 is equipped with a motor 11 facing downward. The bottom of the motor 11 is provided with a drive shaft 12, which passes through the first U-shaped frame 4. A second U-shaped frame 5 is rotatably installed inside the first U-shaped frame 4.

[0058] The transmission assembly 6 is installed inside 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 the transmission shaft 13. A drill bit 14 is installed at the bottom 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 with 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] Regardless of where the sliding seat 15 drives the transmission shaft 13, the transmission assembly 6 always performs the action of transmitting power between the drive shaft 12 and the transmission shaft 13.

[0060] The second U-shaped frame 5 is mainly a structure for installing the transmission component 6. The second U-shaped frame 5 can drive the drill bit 14 to rotate around the drive shaft 12. Assuming that the drive shaft 12 and the drill bit 14 are coaxial, the above rotation will only drive the drill bit 14 to rotate around itself. When the drill bit 14 moves to a position that is not coaxial with the drive shaft 12, the above rotation will drive the drill bit 14 to rotate around the drive shaft 12. This rotation can adjust the position of the drill bit 14 on the circumference of its location, thereby realizing the adjustment of the drilling position in the circumferential direction.

[0061] The movable chamber 29 is movably installed outside the drill frame 9. A limiting plate 16 is installed outside the movable chamber 29. An airbag 17 is provided between the limiting plate 16 and the drill frame 9. The airbag 17 is regarded as a buffer structure. An air injection pipe 18 is connected to the outside of the movable chamber 29, which penetrates the inner wall of the movable chamber 29 and connects to the inside of the airbag 17. The airbag 17 is inflated by air to drive the limiting plate 16 to expand outward and attach to the wall of the pre-drilled installation hole.

[0062] Inflating the airbag 17 not only causes it to expand, causing the limiting plate 16 to expand outward and be fixed inside the hole wall, but also adjusts the inflation degree of the airbag 17 itself, thereby regulating the cushioning effect of the airbag 17. The greater the inflation degree of the airbag 17, the smaller the cushioning space, and the worse the cushioning effect; the smaller the inflation degree, the larger the cushioning space, and the better the cushioning effect. However, in actual application, 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, it can no longer expand outward. After the airbag 17 is inflated, it expands in the vertical direction. The airbag 17 itself is made of stretchable rubber material. When the airbag 17 expands to a certain extent, it can no longer form a cushioning space. Therefore, it is necessary to control the inflation degree of the airbag 17 to avoid poor cushioning effect.

[0063] In this invention, the drill bit 14 can not only adjust the drilling position along the circumferential direction, but also along the radial direction. With the drive shaft 12 as the central axis, the drill bit 14 can adjust the drilling position radially under the drive of the sliding seat 15, and can also adjust the drilling position circumferentially under the rotation of the second U-shaped frame 5. In general, the combination of drilling adjustment in the two directions can realize the adjustment of the drill bit 14 to any drilling position within a certain range of the plane.

[0064] In this invention, a movable chamber 29 is provided outside the drill frame 9, and a limiting plate 16 is installed outside the movable chamber 29. An airbag 17 is provided between the limiting plate 16 and the movable chamber 29. The airbag 17 forms a buffer effect between the limiting plate 16 and the movable chamber 29. When the drill bit 14 vibrates due to a rigid collision with the rock, the airbag 17 buffers the drill frame 9 as a whole in a direction perpendicular to the drill frame 9, thus preventing the vibration of the drill frame 9 itself from causing the overall structure to vibrate and the drilling direction to deviate.

[0065] In addition, the drill bit 14 can be driven to adjust the drilling position radially by the sliding seat 15. On the one hand, the drilling position can be finely adjusted. On the other hand, by adjusting the drilling position radially and performing the drilling process multiple times in conjunction with the rotation action, a larger radius drilling action can be achieved to drill out the pre-installation hole. The movable chamber 29 is positioned in the pre-installation hole by means of the inflatable airbag 17, which realizes the buffer between the hole wall and the drill frame 9, further reducing the linkage vibration effect between the drill frame 9, the propulsion table 7, and the slide 1, and reducing the impact of the vibration action.

[0066] In this invention, the drill bit 14 basically does not produce any vibration or linkage action on the feed platform 7 during operation. To this end, the invention incorporates the following design features: Figure 5 and Figure 6 As shown, the top of the drill frame 9 is provided with a force application groove 19; the bottom of the connecting rod 8 is connected to a connecting seat 20, which is located in the force application groove 19.

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

[0068] Under the influence of gravity, the drill frame 9 will inevitably be at the bottom of the connecting rod 8, and the connecting seat 20 will be at the opening in the force application groove 19. Due to size limitations, the connecting rod 8 and the drill frame 9 cannot be separated, and the connecting rod 8 and the drill frame 9 are not connected. Furthermore, the end of the connecting rod 8 can move within the force application groove 19.

[0069] During the drilling of the pre-installation hole, under the support of the rock at the bottom of the drill frame 9, the connecting seat 20 gradually moves to the bottom of the force application groove 19, and drives the drill frame 9 to move down through the force application groove 19.

[0070] In this invention, the pre-installation hole is generally larger than the rock hole to be drilled. The pre-installation hole is used to install the limiting plate 16, which transforms the linkage effect of the drill frame 9 shaking and causing the whole machine to shake into the linkage between the drill frame 9 and the limiting plate 16. The shaking of the drill frame 9 along its own vertical direction (lateral direction) will cause the air bag 17 to shake. The air bag realizes the buffering of the shaking action between the drill frame 9 and the limiting plate 16.

[0071] In addition, the vibration of the drill frame 9 along its own vertical direction will not cause the connecting rod 8 to vibrate, which avoids the vibration of the drill frame 9 causing the overall structure to vibrate.

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

[0073] In this invention, such as Figure 7 , Figure 8 As shown, the transmission assembly 6 realizes the transmission connection between the transmission shaft 13 and the drive shaft 12. The transmission assembly 6 adopts the following preferred embodiment. The transmission assembly 6 includes a first transmission disk 61, a second transmission disk 62, and a third transmission disk 63 installed sequentially from top to bottom with the same radius. The center of the first transmission disk 61 is connected to the bottom of the drive 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 disc 61 and the second transmission disc 63 are connected by a plurality of first transmission plates 64, all of which are in the same direction. The first transmission plates 64 are rotatably mounted on the first transmission disc 61 via a first connecting shaft 65 and rotatably mounted on the second transmission disc 62 via a second connecting shaft 66.

[0075] The second transmission disc 62 and the third transmission disc 63 are connected by a number of second transmission plates 67. The second transmission plates 67 are all in the same direction. The second transmission plates 67 are rotatably mounted on the second transmission disc 62 via a third connecting shaft 68, and mounted on the third transmission disc 63 via a fourth connecting shaft 69.

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

[0077] like Figure 9 As 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. Under the drive of the sliding seat 15, the third transmission disc 63 moves along the length direction of the second U-shaped frame 5, as shown. Figure 10 As shown, during this process, the second transmission plate 67 will exert a squeezing force on the second transmission disk 62, causing the second transmission disk 62 to move in a direction perpendicular to the movement of the third transmission disk 63. During this process, the distance between the central axes of the third transmission disk 63 and the second transmission disk 62 remains unchanged, and the distance between the central axes of the first transmission disk 61 and the second transmission disk 62 also remains unchanged. Furthermore, the first transmission disk 61, the second transmission disk 62, and the third transmission disk 63 always maintain a synchronous rotational transmission relationship.

[0078] In this invention, the second U-shaped frame 5 can rotate within the first U-shaped frame 4 to drive the radially adjusted sliding seat 15 to rotate. To drive the rotation of the second U-shaped frame 5, this invention is designed as follows: Figure 8 As shown, a ring seat 21 is installed at the top of the second U-shaped frame 5, and a toothed groove is provided on the outer periphery of the ring seat 21. A ring mounting seat 22 is installed at the bottom of the first U-shaped frame 5, and the top of the ring seat 21 extends into the ring mounting seat 22 and can rotate inside the ring mounting seat 22.

[0079] The drive shaft 12 passes through the ring seat 21 and the ring mounting seat 22.

[0080] The annular mounting base 21 has a notch 23 on its side, and at least a portion of the outer periphery of the annular base 21 extends beyond the notch 23.

[0081] The first U-shaped frame 4 is equipped with a first drive motor 24. The bottom end of the first drive motor 24 is connected to a drive gear 25. The drive gear 25 meshes with the tooth 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 this invention, to push the sliding seat 15 to slide, the invention is designed as follows, such as... Figure 8 As shown, the second U-shaped frame 5 has a sliding groove 26 for sliding seat 15. Both sides of the sliding groove 26 are equipped with drive cylinders 27. The output end of the drive cylinder 27 is connected to a push rod 28. The push rod 28 passes through the inner wall of the sliding groove 26 and faces the side of the sliding seat 15.

[0084] The drive cylinder 27 drives the push rod 28 to apply a thrust to the sliding seat 15. By controlling the length of the push rods 28 on both sides, the position of the sliding seat 15 in the slide groove 26 can be controlled.

[0085] In this invention, the transmission component 6 can also reduce the vibration of the drill bit 14 in a certain direction. Assuming that the drill bit 14 vibrates along the direction of the slide groove 26, it will cause the positions of the third transmission disk 63 and the second transmission disk 62 to change. The first transmission disk 61, the second transmission disk 62, and the third transmission disk 63 always maintain a synchronous rotation transmission relationship. The transmission component 6 will only change its own position slightly under the condition of vibration, and will not directly transmit the vibration to the drive shaft 12 to achieve anti-vibration along the direction of the slide groove 26.

[0086] In this invention, after the height position of the movable chamber 29 relative to the limiting plate 16 is fixed, it cannot be moved down. At this time, it is necessary to perform the action of moving down to drill. For this purpose, the invention is designed as follows: sliding plates 30 are symmetrically installed inside the movable chamber 29, directly opposite the drill frame 9. A connecting plate 31 is installed outside the drill frame 9. The connecting plate 31 is slidably disposed between the two sliding plates 30. The bottom of the sliding plates 30 is closed, and a spring is provided between the connecting plate 31 and the closed bottom of the sliding plates 30.

[0087] After the movable chamber 29 is fixed at a specific height in the pre-installation hole along with the limiting plate 16, the propulsion platform 7 continues to advance, and the drill frame 9 is pushed down through the connecting rod 8. During this process, the connecting plate 31 slides between the slide plates 30, the spring is gradually squeezed, and the drill frame 9 moves down, driving the drill bit 14 to move down to drill a hole.

[0088] To achieve the telescopic adjustment of the airbag 17 itself, the present invention makes the following design, such as Figure 2 and Figure 3 As shown, a ventilation pipe 32 is provided inside the movable pod 29. The ventilation pipe 32 is connected to the airbag 17 and the air injection pipe 18. A pneumatic drive structure 33 is installed on the propulsion platform 7. The air injection pipe 18 is connected to the pneumatic drive structure 33.

[0089] In the above embodiments, the air-driven structure 3 can be connected to an external air source, and an air pump can be installed inside the air-driven structure 3 to draw the air source into the air injection pipe 18 and inflate the air bag 17.

[0090] In this invention, the propulsion structure 10 can propel the propulsion platform 7 and the drill frame 9. The propulsion structure 10 adopts the following preferred embodiment, which includes a propulsion cylinder and a chain 101 installed in the slide 1.

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

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

[0093] In this invention, the slide 1 can rotate to adjust its own angle, thereby adjusting the overall forward angle of the drill frame 9 and the drilling angle. To this end, the invention is designed as follows: 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 slide 1. By driving the hydraulic cylinder 34 to push the side wall of the drill frame 9, the angle of the drill frame 9 is adjusted.

[0094] Mounting bracket 3 is fixedly installed on the traveling structure or fixed platform 35. The traveling structure can be a tracked vehicle, etc.

[0095] In this invention, the drill bit 14 can be configured with a detachable threaded connection, thereby allowing the replacement of drill bits 14 of different diameters in different application scenarios.

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

[0097] The drilling angle is preset, and the angle of the drill frame 9 is adjusted by driving the hydraulic cylinder 34, and the position of the mounting bracket 3 is adjusted so that the drill frame 9 is facing the position to be drilled;

[0098] First, the large-diameter drill bit 14 is installed on the drive shaft 13. The propulsion structure 10 pushes the propulsion table 7 forward along the slide rail 2, and the connecting rod 20 drives the drill frame 9 to move forward gradually.

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

[0100] If the diameter of the pre-installation hole obtained by a single drilling is insufficient to install the limiting plate 16 and the movable chamber 29, the position of the sliding seat 15 is adjusted by the drive cylinder 27, and the position of the drill rod 14 is adjusted by the first drive motor 24 driving the second U-shaped frame 5 to rotate. The position is adjusted multiple times and drilling is performed to obtain a pre-installation hole with a larger diameter, so that the limiting plate 16 can be installed.

[0101] Inflate the airbag 17. The airbag 17 expands to drive the limiting plate 16 to expand outward and attach to the wall of the pre-drilled mounting hole.

[0102] The movable chamber 29 is fixed at a height within the pre-installation hole. Then, the propulsion structure 10 continues to advance from its original position, pushing the drill frame 9 forward via the connecting rod 8. The drill frame 9 moves forward relative to the movable chamber 29, enabling drilling into deeper rock layers.

[0103] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
