Description

Technical Field

[0001] The present invention relates to the technical field of anti-bumping drilling vehicles, and in particular to an anti-bumping comprehensive drilling vehicle for coal mines. Background Art

[0002] Anti-bumping drilling vehicles are high-performance drilling equipment designed specifically for coal mines. They are mainly used for drilling operations in coal mine tunnels to release coal seam pressure and prevent rock burst accidents. These drilling vehicles are usually highly automated and intelligent, and can achieve safe and efficient drilling operations in complex coal mine environments. Anti-bumping drilling vehicles artificially change the stress distribution of coal seams by drilling specific holes in the coal seams, thereby reducing the stress concentration inside the coal seams and reducing the probability of rock burst events. Anti-bumping drilling vehicles can effectively perform anti-bumping tasks and provide important guarantees for safe production in coal mines.

[0003] When performing anti-bumping drilling, the purpose of destroying and softening the coal seam can be achieved by drilling a hole with a larger diameter in the coal seam, and the stress near the drill hole will be released. The large-diameter drilling technology can effectively consume the elastic energy stored in the coal seam, reduce the accumulation of energy, and reduce the risk of impact. After large-diameter drilling, the pressure in the coal seam is released, and coal seam debris may fall into the hole obtained by drilling. Therefore, the hole needs to be expanded, reinforced, and other necessary structural treatments are required to ensure that the hole can meet the requirements of subsequent construction. After the traditional anti-bumping drilling vehicle performs large-diameter drilling, it needs to wait for other equipment specially used for reinforcing the hole to process the hole. In this process, coal and rock debris may fall into the hole, which will cause the hole to be enlarged and difficult to fix in the later stage. Therefore, in order to be able to reinforce large-diameter holes in time, we proposed a comprehensive anti-bumping drilling vehicle for coal mines. Summary of the Invention

[0004] The present invention provides an anti-bumping integrated drilling vehicle for coal mines, which solves the problem in the prior art that traditional anti-bumping drilling vehicles cannot reinforce the holes in time after drilling holes with large diameters.

[0010] The stabilizing mechanism includes a second driving cylinder, a linkage rod, a support seat and a collar.

[0011] The output end of the driving cylinder 2 is inclined toward a side close to the drilling rig frame. A supporting groove is provided on one end of the baffle 1 and the baffle 2 close to the sliding ring. The supporting groove and the supporting seat are detachable.

[0012] The working principle and beneficial effects of the present invention are:

[0013] 1. In the present invention, baffle plate 1 and baffle plate 2 are provided. When drilling, the drill rod is drilled through the circular through hole formed by four arc-shaped plates. The sliding bars on both sides of baffle plate 1 are set at 90 degrees. When the two baffle plates 1 and the two baffle plates 2 move away from or approach each other at the same time, baffle plate 2 slides on baffle plate 1.

In the present invention, by providing a support seat and a support groove, when the output ends of the four driving cylinders 2 are extended, the distance between the four support seats gradually becomes farther, and the support seat extends into the support groove to push the baffle 1 and the baffle 2 to move. As the baffle 1 and the baffle 2 are closer to the coal seam, the four support seats respectively push the two baffles 1 and the two baffles 2 away from each other, and the baffle 2 slides on the sliding bar. Due to the sliding bar, the distance between the two baffles 1 and the two baffles 2 remains the same. When the baffle 1 and the baffle 2 gradually move away from each other, the hook-shaped plates on the fixed plate 1 and the fixed plate 2 gradually extend into the coal seam, making the combination of the baffle 1 and the baffle 2 and the coal seam more firmly. At the same time, the four arc plates gradually expand in the hole to fix the hole.

[0015] 3. In the present invention, by setting a stabilizing mechanism, it can stabilize the hole during drilling, and can also drive baffle 1 and baffle 2 to reinforce the hole. By setting a shielding and reinforcing mechanism, it can shield the fallen coal blocks during drilling, and can also reinforce the hole after drilling. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 6 As shown, this embodiment proposes an anti-collision comprehensive drilling vehicle for coal mines, including a drilling vehicle platform 1, a mechanical arm 2 is rotatably provided on the drilling vehicle platform 1, and is characterized in that it also includes a drilling mechanism, a stabilizing mechanism and a shielding and reinforcing mechanism. The drilling mechanism is rotatably provided on the mechanical arm 2 at one end away from the drilling vehicle platform 1, the drilling mechanism is used to drill a coal seam, a plurality of stabilizing mechanisms are provided, and the plurality of stabilizing mechanisms are circumferentially arranged in the drilling mechanism, the stabilizing mechanism is used to support and stabilize the coal seam when the drilling mechanism is drilling, the shielding and reinforcing mechanism is provided on one end of the drilling mechanism, and the shielding and reinforcing mechanism is used to support and stabilize the coal seam when the drilling mechanism is drilling. The drilling mechanism is shielded and protected during drilling, and is used to reinforce the hole after drilling is completed. The shielding and reinforcing mechanism includes a driving assembly, which is arranged on one end of the drilling mechanism. A baffle assembly is detachably provided on the driving assembly. The driving assembly is used to drive the baffle assembly to rotate, and the baffle assembly is used to reinforce the borehole. When drilling is performed by the drilling mechanism, the stabilizing mechanism supports and stabilizes the drilling mechanism, and the shielding and reinforcing mechanism shields the fallen coal and rock. When drilling is completed, the supporting mechanism drives the shielding and reinforcing mechanism to reinforce the hole to prevent a large amount of coal blocks in the coal seam from falling.

[0026] like Figure 3 As shown, the drilling mechanism includes a drill frame 3, a drive cylinder 4 and a drill head 5. The drill frame 3 is configured to be a through-cylinder, the drill frame 3 is rotatably connected to the mechanical arm 2, a plurality of drive cylinders 4 are provided, and the plurality of drive cylinders 4 are fixedly installed inside the drill frame 3. The drill head 5 is slidably arranged in the drill frame 3, and the drill head 5 is connected to the output end of the drive cylinder 4. A plurality of grooves 6 are provided on one end of the drill frame 3, and a protrusion is provided on one side of the groove 6. The grooves 6 correspond to the stabilizing mechanism one by one. In this embodiment, four grooves 6 are provided, and the protrusions on the sides of the four grooves 6 are circumferentially arranged on the drill frame 3. When the baffle 12 and the baffle 2 14 rotate on the annular track 8 through the sliding ring 9, the baffle 1 and the baffle 2 14 stop rotating when they contact the protrusion. At this time, the support seat 20 is below the support groove 22.

[0027] like Figures 1 to 6As shown, the driving assembly includes a motor 7, an annular track 8 and a sliding ring 9. The motor 7 is fixedly mounted on the outside of the drilling rig frame 3, and the motor 7 is arranged at one end of the drilling rig frame 3 where a groove 6 is provided. A gear is provided on the output end of the motor 7. The annular track 8 is fixedly mounted on the outside of the drilling rig frame 3, and the annular track 8 is arranged on the side of the motor 7. The sliding ring 9 is sleeved on the outside of the annular track 8. The sliding ring 9 is slidably arranged on the annular track 8. A gear ring is provided on the sliding ring 9, and the gear is meshed with the gear ring. A plurality of fixing clips 10 are provided on the side of the sliding ring 9 close to the groove 6, and an elastic claw 11 is provided on the fixing clip 10. The fixing clip 10 is provided with a groove 6 corresponding to the baffle 2 14. When the two baffles 2 14 are fixed on the fixing clip 10, the elastic claw 11 presses the baffle 2 14 onto the fixing clip 10. A spring plate with a rear elasticity is provided on the elastic claw 11. When the output end of the driving cylinder 2 18 pushes the baffle 1 12 and the baffle 2 14 toward the hole, the elastic claw 11 bends and separates from the baffle 2 14.

[0028] like Figures 3 to 6 As shown, the baffle assembly includes a baffle 12 and a baffle 2 14, two baffles 12 are provided, and the two baffles 12 are arranged opposite to each other. Sliding bars 13 are provided on both sides of the baffle 12, and two baffles 14 are provided, and the two baffles 14 are arranged opposite to each other. The two baffles 12 and the two baffles 14 are staggered around the drill head 5, and the sliding bar 13 is slidably connected to the baffle 2 14. The baffle 2 14 is detachably connected to the fixing clamp 10. Arc plates 15 are provided at positions close to the baffles 12 and the baffles 2 14. The four arc plates 15 surround each other to form a circular through hole. The through hole formed by the arc plates 15 is aligned with the drill head 5. A fixing plate 16 is provided on the arc plate 15. The baffle 12 and the baffle A fixing plate 2 17 is provided on each of the two baffles 14. When drilling, the drill rod is drilled through the circular through hole composed of the four arc-shaped plates 15. The sliding bars 13 on both sides of the baffle 12 are set at 90 degrees. When the two baffles 12 and the two baffles 2 14 move away from or approach each other at the same time, the baffle 2 14 slides on the baffle 12. The arc-shaped plates 15 are set to a 90-degree fan shape. The four arc-shaped plates 15 can form a circular through hole. There are hook-shaped parts on the fixing plate 16 and the fixing plate 2 17. When the fixing plate 16 and the fixing plate 2 17 slide when extending into the coal seam, the hook-shaped part extends into the coal seam, which can make the combination of the fixing plate 16, the fixed plate 2 17 and the coal seam tighter, thereby avoiding falling when reinforcing the hole.

[0029] like Figures 4 to 6As shown, the stabilizing mechanism includes a second driving cylinder 18, a linkage rod 19, a support seat 20 and a collar 21. The second driving cylinder 18 is rotatably arranged inside the drilling rig frame 3, the linkage rod 19 is arranged on the output end of the second driving cylinder 18, the support seat 20 is rotatably arranged on the end of the linkage rod 19 away from the second driving cylinder 18, the collar 21 is rotatably arranged on the drilling rig frame 3, and the linkage rod 19 is slidably arranged in the collar 21. As the output end of the second driving cylinder 18 extends to push the linkage rod 19 to slide in the collar 21, the distance between the four support seats 20 gradually increases.

[0030] like Figures 4 to 6 As shown, the output end of the driving cylinder 2 18 is inclined toward the side close to the drilling frame 3, and a support groove 22 is provided on the end of the baffle 1 12 and the baffle 2 14 close to the sliding ring 9. The support groove 22 and the support seat 20 are detachably provided. The driving cylinder 2 18 is rotatably connected to the drilling frame 3, and the distance between the driving cylinder 2 18 and the drilling frame 3 is farther than the distance between the collar 21 and the drilling frame 3. Therefore, when the output ends of the four driving cylinders 2 are extended, the distance between the four support seats 20 gradually becomes farther. After the support seat 20 is extended into the support groove 22, it pushes the baffle 1 12 and the baffle 2 14 to move. As the baffle 1 12 and baffle 2 14 are closer to the coal seam, and the four support seats 20 push the two baffles 12 and the two baffles 14 away from each other, and the baffle 2 14 slides on the sliding bar 13. Due to the sliding bar 13, the distance between the two baffles 12 and the two baffles 14 remains the same. When baffle 12 and baffle 2 14 gradually move away from each other, the hook-shaped plates on the fixed plate 16 and the fixed plate 2 17 gradually extend into the coal seam, making the combination of baffle 12 and baffle 2 14 and the coal seam more firm. At the same time, the four arc-shaped plates 15 gradually expand in the hole to fix the hole.

[0031] After the drill rig platform 1 moves to the position close to the drilling hole, the mechanical arm 2 rotates to support the drill frame 3, and the drill frame 3 rotates on the mechanical arm 2, and one end of the circular track 8 is aligned with the drilling position, and the drill rod is passed into the drill head 5. The drill head 5 drives the rotating rod to rotate, and the output end of the drive cylinder 1 4 is shortened to drive the drill head 5 toward the drilling position. After the drill rod passes through the through hole formed by the arc plate 15, the drilling position is drilled. The output end of the drive cylinder 2 18 is extended, and the linkage rod 19 slides on the collar 21. The support seat 20 is supported by the linkage rod 19 and moves toward the coal seam in the groove 6. The support seat 20 contacts the coal seam to stabilize the drill frame 3. The coal and rock blocks that fall during drilling fall on the baffle 1 12 and the baffle 2 14 to prevent the coal and rock blocks from affecting the drill head 5. When the drilling is completed, the output end of the drive cylinder 2 18 is shortened to pull the linkage rod 19 to slide, and the support seat 20 moves to the groove 6 In the process, the output end of the motor 7 drives the gear to rotate, and the gear drives the sliding ring 9 to rotate on the sliding track through the gear ring, and the fixed clamp 10 drives baffle 12 and baffle 2 14 to rotate. When baffle 2 14 rotates to contact the protrusion on the side of the groove 6, it stops rotating. At this time, the output end of the driving cylinder 2 18 extends to push the linkage rod 19 to slide, and the support seat 20 extends into the support groove 22. The four support seats 20 push baffle 1 12 and baffle 2 14 to move toward the hole, and the arc plate 15 and the fixed plate 1 16 and the fixed plate 2 17 extend into the coal seam. Since the driving cylinder 2 18 is inclined, as the support seat 20 gradually moves away from the groove 6, the distance between the four support seats 20 gradually becomes farther, and the four support seats 20 push the distance between baffle 1 12 and baffle 2 14 to become farther, and baffle 2 14 slides on the sliding bar 13, and the hook plates on the fixed plate 16 and the fixed plate 2 17 extend into the coal seam for fixation.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
