Description

Technical Field

[0001] This invention relates to the field of iron ore mining drilling rigs, and in particular to underground iron ore mining drilling rigs for hard rock formations. Background Technology

[0002] Hard rock rigs for underground iron ore mining are specialized drilling equipment designed for hard iron ore formations (f=10-16) such as quartz iron ore and magnetite hard rock. They are primarily used for drilling blasting holes, support holes, and exploration holes in underground iron ore mines. Adaptable to harsh working conditions such as narrow underground tunnels, high humidity and dust, and heavy-duty impacts, they are characterized by "high-efficiency rock breaking, stable positioning, and wear resistance." Through a composite rock breaking method of high-frequency impact and high-torque rotation, they overcome the difficulties of drilling in hard rock formations while also considering energy saving, consumption reduction, and underground operational safety. They are a core piece of equipment for the large-scale, high-efficiency mining of hard rock underground iron ore.

[0003] However, most existing drilling rigs used in hard iron ore formations are percussion drills to improve drilling efficiency. However, these percussion drills experience significant vibrations during operation, which can cause the equipment to shift even under fixed conditions due to continuous vibration. Furthermore, the vibrations of the drill itself increase energy consumption. Therefore, a drilling rig specifically designed for underground iron ore mining in hard rock formations is proposed. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this invention proposes an underground iron ore drilling rig for hard rock formations, which can effectively stabilize the percussion drilling rig, improve drilling stability and reduce energy consumption.

[0005] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

[0006] A drilling rig for underground iron ore mining in hard rock formations includes a tracked vehicle. Two electrically adjustable seats are mounted on the upper part of the tracked vehicle, and a steering shaft is connected between the two seats. A through-slot is formed on the tracked vehicle. Guide rails are installed on the front and rear inner walls of the through-slot. Slides are symmetrically slidably mounted on the left and right sides of the guide rails. Supports extending to the outside of the through-slot are connected to the ends of the slides on the left and right sides, and mounting frames are connected to the ends of the supports away from the slides. A shaft is rotatably mounted on the front and rear sides of each mounting frame. A support plate is mounted on the shaft, and a gear is also mounted on the shaft. A rack frame that meshes with the gear is slidably mounted on the mounting frame.

[0007] The mounting frame is equipped with an adjustment component. This component rotates the support plate on shaft one to a horizontal position when the two side slides move closer together, and when the two side slides move away from each other, it causes the support plate on shaft one to rotate freely and fall to contact the ground. A locking pin is connected to the rack frame. The mounting frame is also equipped with a locking component. This component adaptively locks each locking pin when each support plate rotates freely and falls to contact the ground, ensuring the support plate contacts the ground. Arc-shaped toothed sleeves are slidably installed on both sides of the upper end face of the tracked vehicle. Gear rings that engage with the arc-shaped toothed sleeves are fitted at both ends of the steering shaft. A stabilizing component is installed on the slide. This component drives the arc-shaped toothed sleeves and gear rings to engage when the two side slides move away from each other, thus stabilizing the steering shaft.

[0008] Preferably, a mounting plate is installed on the front side of the steering shaft, and telescopic components are installed at both ends of the front side of the mounting plate. The front output ends of the telescopic components on both sides are connected to guide frames. A frame is slidably fitted between the guide frames on both sides, and a drilling rig is installed inside the frame.

[0009] Preferably, telescopic components are installed on both sides of the upper surface of the tracked vehicle, and the front and rear ends of each slide are slidably sleeved in the front and rear guide rails. The left and right sides of the front and rear guide rails are symmetrical independent drive structures to control the slides on both sides to move closer or further apart.

[0010] Preferably, the front and rear support plates are connected to the front and rear shafts respectively at their close ends, while the front and rear support plates are rotatably mounted with shafts, and support feet are fitted on the shafts.

[0011] Preferably, the adjusting assembly includes a connecting plate, an inclined frame, a first sleeve frame, and a top rod. The connecting plate is connected to the bottom of the rack frame, the inclined frame is connected to the end of the connecting plate near the slide, the first sleeve frame is connected to the inner wall of the through groove, and is arranged on both the left and right sides of the inner wall of the through groove. The top rod is connected to the lower end of the sleeve frame and slides and abuts against the inclined frame on the connecting plate at the lower end of the front and rear rack frames.

[0012] Preferably, a sliding frame is connected to the mounting bracket, a sliding plate is connected to the rack frame, the sliding plate is slidably fitted inside the sliding frame, a sliding rod frame is connected to both the front and rear sides of the lower end of the mounting bracket, the connecting plates on the front and rear sides are respectively slidably fitted outside the sliding rod frames on the front and rear sides, a tension spring fitted outside the sliding rod frame is connected between the upper surface of the connecting plate and the lower end of the mounting bracket, and the bracket is slidably fitted inside the frame.

[0013] Preferably, the positioning assembly includes a second sleeve frame, connecting rods, a retaining sleeve, a horizontal plate, and a sleeve plate. The second sleeve frame is connected to the front and rear sides of each mounting bracket and is sleeved on the outer side of the corresponding retaining post. The connecting rods slide through both sides of the second sleeve frame. The retaining sleeves are connected to the ends of the connecting rods on both sides inside the second sleeve frame that are close to each other and cooperate with the retaining post. The horizontal plate is connected to the ends of the connecting rods on both sides outside the second sleeve frame that are far apart from each other. Pull plates are slidably provided at the ends of the second sleeve frame on both the front and rear sides that are far apart from each other, and the two ends of the pull plates are rotatably connected to the horizontal plates on both sides by a first rotating plate. The sleeve plate is slidably sleeved on the front and rear inner walls of the through groove and abuts against the side of the tracked vehicle. Each sleeve plate is rotatably connected to the pull plate on its respective side by a second rotating plate.

[0014] Preferably, the locking pin slides within the second sleeve frame, and each of the front and rear sides of the second sleeve frame is connected to a sliding rod frame two on the side furthest from each other. The pull plate is slidably sleeved on the outside of the sliding rod frame two on its respective side. A spring sleeved on the outside of the sliding rod frame two connects the end of the pull plate furthest from the second sleeve frame two to the end of the sliding rod frame two. The inner walls of the front and rear of the through groove are connected to slide rails, and the slide rails are connected to stops on the side of the tracked vehicle. Each sleeve plate is slidably sleeved on the slide rail on its respective side and cooperates with the stops on the slide rail to abut.

[0015] Preferably, the stabilizing component slide bar frame three is connected to the arc-shaped toothed sleeve and slides on the upper surface of the tracked vehicle, and the slide bars on both sides are rotatably connected to the two side slide bar frames three.

[0016] Preferably, the inner wall of the through groove is provided with slide rails on both the left and right sides, and the slide rails on both sides are connected to vertical frames that slide in the slide rails. The upper end of the vertical frame extends to the top of the tracked vehicle and is rotatably connected to the rotating plate three at the extended end. The upper surface of the tracked vehicle is also connected to the two sides of the sleeve, and the slide rod frame three is slidably sleeved in the sleeve on each side.

[0017] The beneficial effects of this invention are:

[0018] 1. The technical solution of this invention controls the tracked vehicle to move the drilling rig to a designated position and drives the electric adjustment seat and guide frame to operate. The drilling rig is adjusted to the required angle and then drilling can be performed. Before drilling, the guide rails on both sides are controlled to move, causing the slides on both sides to move away from each other, so that the supports and mounting frames on both sides move away from each other. During the process, the inclined frames on the mounting frames on the left and right sides will gradually move the tracked vehicle away from the top rod, so as to eliminate the contact with the top rod. Then, under the action of the tension spring and the weight of the support plate itself, the support plate rotates downward about the first shaft until it is in contact with the ground. During the process, the rack frame will be driven to move upward. Due to the uneven ground, each support plate will rotate at a different angle, so that each rack frame moves upward at a different height. In this way, each support plate can be adaptively placed on the uneven ground during drilling to facilitate subsequent stable support. During movement, the slides on both sides can be adjusted to move closer to each other, so that the inclined frame and the top rod are in contact and drive the rack frame to move downward, and drive the gear and the support plate to rotate to a horizontal state to facilitate the movement of the tracked vehicle.

[0019] 2. The technical solution of this invention is that after each support plate is adaptively placed on the ground, as the two side slides continue to move away from each other, the sleeve plate that moves with the slide, bracket and mounting frame will gradually come into contact with the end of the slide rail, that is, the stop block at the end of the slide rail near the side of the tracked vehicle, so that the sleeve plate will no longer slide. Then the continued sliding of the slide will make the sleeve plate move away from the mounting frame and pull the rotating plate two to drive the pulling plate away from the sleeve frame two, thereby driving the rotating plate one to rotate, pulling the horizontal plates, connecting rods and sleeves on both sides to move closer to each other and to engage the locking pins on the rack frame that adaptively move up to different heights. After the locking pins are stably engaged, the position of the rack frame is fixed. At this time, the support plate will no longer be able to rotate freely, thus achieving stable support with the ground. Moreover, multiple supports can achieve multi-point adaptive stable support. With the extension part two extending upward to support the top of the mine, the stability during drilling is improved, energy consumption is reduced and accuracy is improved.

[0020] 3. The technical solution of the present invention, by moving the two side slides away from each other, can also drive the two side vertical frames away from each other and push the rotating plate three to rotate, so as to drive the slide rod three to move the arc-shaped toothed sleeve close to the toothed ring and perform clamp positioning with the toothed ring adjusted to a specified angle, thereby ensuring the stability of the steering shaft during operation, so as to improve the stability of the drilling rig on the tracked vehicle during drilling, and realize that both the tracked vehicle and the drilling rig on it can be stable during drilling, ensuring drilling accuracy and further reducing energy consumption.

[0031] The following will be combined with the appendix Figure 1 To be continued Figure 8 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] like Figure 1-8As shown, the present invention discloses an underground iron ore drilling rig for hard rock formations, including a tracked vehicle 1. Two electric adjustment seats 2 are installed on the upper end of the tracked vehicle 1, and a steering shaft 3 is connected between the two electric adjustment seats 2. A through slot 9 is opened on the tracked vehicle 1. Guide rails 11 are installed on the inner walls of the front and rear sides of the through slot 9. Slide frames 12 are symmetrically slidably mounted on the left and right sides of the guide rails 11. The ends of the slide frames 12 on the left and right sides that are far apart from each other are connected to brackets 13 extending to the outside of the through slot 9. The end of the bracket 13 that is far away from the slide frame 12 is connected to a mounting frame 14. A shaft 15 is rotatably mounted on the front and rear sides of each mounting frame 14. A support plate 16 is mounted on the shaft 15, and a gear 19 is also mounted on the shaft 15. A rack frame 22 that meshes with the gear 19 is slidably arranged on the mounting frame 14.

[0034] The mounting frame 14 is equipped with an adjustment component. When the two side slides 12 slide close to each other, the adjustment component drives the support plate 16 on the shaft 15 to rotate to a horizontal state. When the two side slides 12 move away from each other, the support plate 16 on the shaft 15 rotates freely and falls to contact the ground. The rack frame 22 is connected with a locking post 23. The mounting frame 14 is also equipped with a locking component. The locking component is used to adaptively lock the locking post 23 when each support plate 16 rotates freely and falls to contact the ground, so as to achieve the contact between the support plate 16 and the ground. Arc-shaped toothed sleeves 44 are slidably provided on both sides of the upper end face of the tracked vehicle 1. Both ends of the steering shaft 3 are fitted with toothed rings 45 that cooperate with the arc-shaped toothed sleeves 44 on both sides. The slide 12 is equipped with a stabilizing component. The stabilizing component is used to drive the arc-shaped toothed sleeves 44 and toothed rings 45 to engage when the two side slides 12 move away from each other, and to stabilize the steering shaft 3.

[0035] A mounting plate 4 is installed on the front side of the steering shaft 3. Telescopic components 5 are installed at both ends of the front side of the mounting plate 4. Guide frames 6 are connected to the front output ends of the telescopic components 5 on both sides. A frame 7 is slidably fitted between the guide frames 6 on both sides, and a drilling rig 8 is installed inside the frame 7.

[0036] Among them, the electric adjustment seat 2 is the existing drive seat with a motor. The two ends of the steering shaft 3 are connected to the output ends of the motors in the electric adjustment seats 2 on both sides, so as to realize electric rotation and facilitate the adjustment of the pitch angle of the drilling rig 8. The guide frame 6 is an existing device that is fixed itself but can drive the related equipment to slide linearly, so as to control the sliding of the guide frame 6 and further improve the flexibility of adjusting the drilling rig 8. The telescopic part 5 can also adjust the distance between the drilling rig 8 and the tracked vehicle 1.

[0037] The tracked vehicle 1 has telescopic components 41 installed on both sides of its upper surface. The front and rear ends of each slide 12 are slidably fitted into the front and rear guide rails 11. The left and right sides of the front and rear guide rails 11 are symmetrical and independently driven structures to control the slides 12 on both sides to move closer or further apart.

[0038] The extension component 41 allows it to extend so that it can contact the top of the mine when operating inside the mine, further improving the stability of the tracked vehicle 1.

[0039] The front and rear support plates 16 are connected to the front and rear shafts 15 respectively at their close ends, while the front and rear support plates 16 are rotatably mounted with shafts 17 at their far ends, and support feet 18 are fitted on shafts 17.

[0040] The support foot 18 is designed so that it can always face downward under its own weight, and remains facing downward when the support plate 16 rotates downward until it is in contact with the ground, thereby increasing the area of ​​the support plate 16 supporting the ground, forming surface support, and improving the stability of the support.

[0041] Example 2:

[0042] like Figure 1-8 As shown, the present invention discloses an underground iron ore mining drill for hard rock formations. Compared with Embodiment 1, this embodiment discloses the structure of the adjustment component.

[0043] The adjustment assembly includes a connecting plate 24, an inclined frame 25, a sleeve frame 28, and a top rod 29. The connecting plate 24 is connected to the bottom of the rack frame 22. The inclined frame 25 is connected to the end of the connecting plate 24 near the slide 12. The sleeve frame 28 is connected to the inner wall of the through groove 9 and is arranged on both the left and right sides of the inner wall of the through groove 9. The top rod 29 is connected to the lower end of the sleeve frame 28 and slides and contacts the inclined frame 25 on the connecting plate 24 at the lower end of the rack frame 22.

[0044] A sliding frame 20 is connected to the mounting bracket 14, and a sliding plate 21 is connected to the rack frame 22. The sliding plate 21 is slidably fitted inside the sliding frame 20. The front and rear sides of the lower end of the mounting bracket 14 are connected to the sliding rod frame 26. The connecting plates 24 on the front and rear sides are slidably fitted outside the sliding rod frame 26 on the front and rear sides, respectively. A tension spring 27 fitted outside the sliding rod frame 26 is connected between the upper end face of the connecting plate 24 and the lower end face of the mounting bracket 14. The bracket 13 is slidably fitted inside the sleeve frame 28. The sliding fit of the sliding plate 21 and the sliding frame 20 improves the stability of the rack frame 22 sliding up and down. The sliding fit of the connecting plate 24 outside the sliding rod frame 26 also improves the stability of the connecting plate 24 sliding. Under the action of the tension spring 27, the rack frame 22 has an upward force. Under the action of the weight of the support plate 16, when the inclined frame 25 does not contact the top rod 29, the support plate 16 can fall and rotate freely until it is in contact with the ground.

[0045] In practical use, the tracked vehicle 1 moves the drilling rig 8 to a designated position and drives the electric adjustment seat 2 and guide frame 6 to adjust the drilling rig 8 to the required angle before drilling can begin. Before drilling, the guide rails 11 on both sides are controlled to move, causing the slides 12 on both sides to move away from each other, and the supports 13 on both sides to move away from the mounting frames 14. During this process, the inclined frames 25 on the mounting frames 14 on both sides will gradually move the tracked vehicle 1 away from the top rod 29, thus eliminating the contact with the top rod 29. Then, under the tension of the tension spring 27 and the weight of the support plate 16 itself, the support plate 16 moves away from the shaft. Rotate downwards around 15 until it is in contact with the ground. During this process, the rack frame 22 will move upwards. Due to the uneven ground, each support plate 16 will rotate at a different angle, and thus each rack frame 22 will move upwards at a different height. This allows each support plate 16 to adaptively place on the uneven ground during drilling, facilitating subsequent stable support. During movement, the two side slides 12 can be adjusted to move closer to each other, causing the inclined frame 25 and the top rod 29 to contact and drive the rack frame 22 downwards. This drives the gear 19 and the support plate 16 to rotate to a horizontal position, facilitating the movement of the tracked vehicle 1.

[0046] Example 3:

[0047] like Figure 1-8 As shown, this invention discloses an underground iron ore mining drill for hard rock formations. Compared with Embodiment 2, this embodiment discloses the structure of the positioning component.

[0048] The positioning assembly includes a second sleeve 30, a connecting rod 31, a retaining sleeve 32, a horizontal plate 33, and a sleeve plate 39. The second sleeve 30 is connected to the front and rear sides of the upper end of each mounting bracket 14 and is fitted onto the outside of the corresponding retaining post 23. The connecting rod 31 slides through both sides of the frame 30. The retaining sleeve 32 is connected to the two ends of the connecting rod 31 inside the frame 30, which are close to each other, and cooperates with the retaining post 23 to retain the sleeve. The horizontal plate 33 is connected to the two ends of the connecting rod 31 outside the frame 30, which are far apart from each other. Pull plates 35 are slidably provided at the far ends of the front and rear sides of the frame 30, and the two ends of the pull plates 35 are rotatably connected to the horizontal plates 33 on both sides by rotating plates 36. The sleeve plate 39 is slidably fitted onto the front and rear inner walls of the through groove 9 and abuts against the side of the tracked vehicle 1. Each sleeve plate 39 is rotatably connected to the pull plate 35 on its respective side by rotating plates 40.

[0049] The locking pin 23 slides within the sleeve frame 2 30. The front and rear sides of the sleeve frame 2 30 are each connected to a sliding rod frame 2 34 on the side furthest from each other. Pull plates 35 are slidably fitted onto the outside of their respective sliding rod frames 2 34. A spring 37, fitted onto the outside of the sliding rod frame 2 34, connects the end of the pull plate 35 furthest from the sleeve frame 2 30 to the end of the sliding rod frame 2 34. The inner walls of the through groove 9 are connected to slide rails 38. A stop block is connected to the side of the tracked vehicle 1 on the slide rail 38. Each sleeve plate 39 is slidably fitted onto its respective slide rail 38 and engages with the stop block on the slide rail 38. The stop block allows the sleeve plate 39 to engage with it at one end, and during this movement, the support plate 16 will rotate freely and fall, fitting against the ground. The spring 37 allows the pull plate 35 to slide closer to the sleeve frame 2 30 without external force, causing the two sleeves 32 to move away from each other and not act on the locking pin 23.

[0050] After the various support plates 16 are adaptively placed on the ground, as the two side carriages 12 continue to move away from each other, the sleeve plate 39, which moves with the carriage 12, bracket 13, and mounting frame 14, will gradually come into contact with the stop block at the end of the slide rail 38, that is, the end of the slide rail 38 closest to the side of the tracked vehicle 1. This will prevent the sleeve plate 39 from sliding. Subsequently, the continued sliding of the carriage 12 will cause the sleeve plate 39 to move away from the mounting frame 14, and pull the rotating plate 40 to move the pulling plate 35 away from the sleeve frame 30, thereby driving the rotating plate 1. Rotating 36 pulls the horizontal plates 33, connecting rods 31 and clamping sleeves 32 closer together and clamps the clamping posts 23 on the rack frame 22 that adaptively move upward at different heights. After the clamping posts 23 are stably clamped, the position of the rack frame 22 is fixed. At this time, the support plate 16 will no longer be able to rotate freely, thus providing stable support to the ground. Multiple supports can achieve multi-point adaptive stable support. In conjunction with the telescopic component 41 extending upward to support the top of the mine, it improves stability during drilling, reduces energy consumption, and improves accuracy.

[0051] Example 4:

[0052] like Figure 1-8 As shown, the present invention discloses an underground iron ore mining drill for hard rock formations. Compared with Embodiment 3, this embodiment discloses the structure of the stabilizing component.

[0053] The stabilizing component slide bar frame 3 43 is connected to the arc-shaped toothed sleeve 44 and slides on the upper surface of the tracked vehicle 1. The slides 12 on both sides are rotatably connected to the slide bar frames 3 43 on both sides by rotating plates 3 47.

[0054] Slides 10 are provided on both the left and right sides of the inner wall of the through groove 9. Vertical frames 46 that slide in the slides 10 are connected to the slide frames 12 on both sides. The upper end of the vertical frame 46 extends to the top of the tracked vehicle 1 and is rotatably connected to the rotating plate 3 47 at the extended end. Sleeve seats 42 are also connected to both sides of the upper surface of the tracked vehicle 1. The slide rod frame 3 43 is slidably fitted in the sleeve seat 42 on its respective side.

[0055] This causes the two side slides 12 to move away from each other, and also causes the two side vertical frames 46 to move away from each other, and pushes the rotating plate 3 47 to rotate, so as to push the slide rod frame 3 43 to move the arc-shaped toothed sleeve 44 close to the toothed ring 45 and perform a clamping positioning with the toothed ring 45 on the steering shaft 3 adjusted to a specified angle, thereby ensuring the stability of the steering shaft 3 during operation, so as to improve the stability of the drilling rig 8 on the tracked vehicle 1 during drilling, and realize that both the tracked vehicle 1 and the drilling rig 8 on it can be stable during drilling, ensuring drilling accuracy and further reducing energy consumption.

[0056] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
