Description

Technical Field

[0001] This invention relates to the field of mining or quarrying, and more particularly to a safe continuous drilling apparatus for metal mining. Background Technology

[0002] The metal mining industry is undergoing a technological transformation from traditional blasting methods to continuous and intelligent mining. Continuous drilling rigs, as core equipment, achieve continuous cuttings sampling through double-walled tubing air reverse circulation technology, significantly improving drilling efficiency and sample representativeness. However, existing rigs generally suffer from the drawback of a separate design between the support frame and the drilling system. For example, Chinese invention patent with authorization announcement number CN120575775A discloses a drilling equipment and method for ultra-large diameter boreholes in coal mines, including a moving device that moves along a coal mine roadway, a drilling device mounted on the moving device, and a plurality of drill rod assemblies connected end to end on the output shaft of the drilling device. The drill rod assembly includes a rod body with a spiral propulsion blade on its outer surface, a docking groove provided at one end of the rod body, a receiving groove provided at the other end of the rod body and the end of the output shaft, and a drill bit assembly provided on the farthest drill rod assembly. However, when this continuous drilling rig operates within the mine tunnel, it needs to move frequently to adapt to different working faces. Since the inner wall of the mine tunnel into which the drilling rig is drilled is in a loose state, a support frame needs to be installed on the inner wall of the mine tunnel to maintain stability. As the drilling equipment continues to move, if the support frame cannot move synchronously, the center of gravity of the equipment is prone to deviate from the stable area, especially when operating in soft rock or fault zones, which may cause the roof of the goaf to collapse. Summary of the Invention

[0003] To address the problems mentioned in the background section, the technical solution of this invention is as follows: A safe continuous drilling device for metal mining includes a mobile vehicle body, a support shell on the top of the mobile vehicle body, an upper support mechanism on the top of the support shell for supporting the inner wall of the mine tunnel, and a lower moving mechanism between the upper support mechanism and the support shell for driving the upper support mechanism to move. The lower moving mechanism includes multiple lower support legs arranged on both sides of the moving vehicle body. The top of the multiple lower support legs is provided with a lower connecting rod. An interactive plate is provided at the bottom of the lower connecting rod, and a bent surface for linkage with the upper support mechanism is provided at the end of the interactive plate away from the lower connecting rod. The upper support mechanism includes upper legs disposed on the outside of multiple lower legs, multiple upper connecting rods arranged on the top of the multiple upper legs, and a fixed main board inserted between the multiple upper connecting rods. A rotating seat is disposed on the side of the fixed main board away from the bending surface, and the rotating seat is telescopically connected to the lower connecting rod.

[0004] By adopting the above technical solution, the moving vehicle body moves and contacts the bottom of the interactive plate, thereby driving the lower connecting rod to retract. At the same time, the top of the supporting shell contacts the bottom of the lower connecting rod, thereby controlling the movement state of the lower moving mechanism and the upper supporting mechanism as a whole. The lower moving mechanism interacts with the upper supporting mechanism through the interactive plate, so that after the lower moving mechanism completes its movement, it drives the upper supporting mechanism to move, forming a stepping state and moving synchronously with the moving vehicle body. During the movement, the lower or upper support leg always provides support to maintain the stability of the inner wall of the mine tunnel.

[0005] Preferably, a first fixing seat is fixedly provided on the top of each of the plurality of lower support legs, and the plurality of first fixing seats are respectively inserted and fixed to the plurality of lower connecting rods. A lower stabilizing beam is inserted and fixed on the side of each of the plurality of first fixing seats adjacent to the lower connecting rod. A stop sensor is provided on one side surface of the plurality of lower stabilizing beams near the bending surface, and an extension sensor is provided on the bottom of the lower stabilizing beam on the side of the stop sensor.

[0006] By adopting the above technical solution, the first fixed seat connects the lower support leg and the lower connecting rod, and a lower stabilizing beam is inserted and fixed in the transverse direction to form a three-dimensional stability of the lower support leg, the lower connecting rod and the lower stabilizing beam, thereby increasing the stability of the lower moving mechanism. At the same time, the stop sensor is set to control the relative movement state of the lower moving mechanism and the upper support mechanism, and the extension sensor is set to control the extension state of the upper support leg.

[0007] Preferably, the lower end of the interactive panel has an upward-facing partition groove, and a first extrusion block is fixed in the middle of the inner wall of the partition groove.

[0008] By adopting the above technical solution, the opening of the partition groove provides a fixed space for the first extrusion block, and the extension and retraction of the lower support leg is controlled by the lateral reciprocating movement of the first extrusion block.

[0009] Preferably, a second fixing seat is fixedly provided on the top of each of the multiple upper support legs, and the multiple second fixing seats are respectively inserted and fixed to the multiple upper connecting rods. An upper stabilizing beam is inserted and fixed on the side of each of the multiple second fixing seats adjacent to the upper connecting rods, and multiple fixing auxiliary plates that are inserted and fixed to the upper connecting rods are provided between the multiple fixed main plates.

[0010] By adopting the above technical solution, the second fixed seat connects the upper support leg and the upper connecting rod, and the upper stabilizing beam is interspersed in the transverse plane to form a three-dimensional stability of the upper support leg, the upper connecting rod and the upper stabilizing beam. Then, the fixed main plate and the fixed auxiliary plate fix multiple upper connecting rods side by side, so that the upper support mechanism provides stable support in the mine tunnel.

[0011] Preferably, an electric actuator is rotatably mounted on the side of the rotating seat facing the interactive panel, and a connecting seat is rotatably mounted on the output end of the electric actuator facing the interactive panel. The end of the connecting seat away from the electric actuator is fixedly connected to the lower connecting rod at the top of the interactive panel.

[0012] By adopting the above technical solution, the electric actuator is rotatably connected to the rotating seat and the connecting seat on both sides, thereby avoiding misalignment caused by the lateral extension of the electric actuator. At the same time, the electric actuator is connected to the interactive plate through the connecting seat, thereby forming an integral connection between the lower connecting rod and the upper connecting rod. As the electric actuator extends and retracts, the distance between the lower connecting rod and the upper connecting rod is controlled, providing power for the movement of the lower connecting rod and the upper connecting rod.

[0013] Preferably, an upper rod sensor is provided on the side of the rotating seat away from the interactive panel, and an extrusion plate is provided in the middle of the lower end face of the rotating seat. The extrusion plate abuts against the stop sensor. A second extrusion block is fixed on the top of the support housing on one side of the limiting groove, and the top of the second extrusion block abuts against the upper rod sensor.

[0014] By adopting the above technical solution, when the interactive plate moves, it causes the bending surface to abut against the upper rod sensor, thereby controlling the upper support leg to retract and extend. As the electric push rod retracts, it causes the fixed main board to move, thereby causing the extrusion plate to abut against the stop sensor, thereby controlling the electric push rod to stop retracting. The second extrusion block abuts against the upper rod sensor back and forth, thereby controlling the retraction and extension of the electric push rod.

[0015] Preferably, a limiting groove is formed at the top of the supporting housing, the inner wall of the limiting groove is horizontally inserted into the interactive plate, a lower rod sensor is provided in the middle of the inner wall of the limiting groove, and the top of the lower rod sensor abuts against the first extrusion block.

[0016] By adopting the above technical solution, the opening of the limiting groove provides access space for the insertion of the interactive board, limits the movement of the interactive board, prevents the interactive board from deviating during movement, and at the same time, as the interactive board is inserted, it drives the first pressing block to contact the lower rod sensor, thereby controlling the lower support leg to extend and retract.

[0017] Preferably, the bottom of both sides of the mobile vehicle body is provided with track mechanisms for moving the mobile vehicle body, the top of the mobile vehicle body is fixedly provided with a driver's cab inside the support shell, and the front end of the mobile vehicle body is provided with a drilling structure for crushing ore.

[0018] By adopting the above technical solution, the tracked mechanism drives the mobile vehicle to move within the mine tunnel. The support shell and the cab provide dual protection for the operators. Then, the drilling structure breaks up the minerals in front and creates space for the mobile vehicle to move forward.

[0019] Preferably, the mobile vehicle body is provided with a collection bucket at the bottom of the drilling structure, and guide wheels are rotatably provided on both sides of the surface of the collection bucket. A feeding trough is provided between the two guide wheels in the collection bucket, and a discharge port is provided at one end of the feeding trough through the mobile vehicle body.

[0020] By adopting the above technical solution, the ore crushed by the drilling structure falls downward into the collection hopper, and is then fed into the feed trough by the rotating guide wheel. Finally, it is transported to the rear through the discharge port, thereby completing the ore transportation and preventing the falling ore from obstructing the forward movement of the moving vehicle.

[0021] The beneficial technical effects of the present invention are as follows: 1. By utilizing the movement of the mobile vehicle, the first extrusion block reciprocates with the lower rod sensor, the second extrusion block reciprocates with the extension sensor, the bending surface reciprocates with the upper rod sensor, and the extrusion plate reciprocates with the stop sensor. The mobile vehicle only needs to move to drive the lower and upper support legs to complete the step-by-step advancing action, so that the mobile vehicle always remains under the support and coverage of multiple lower and upper connecting rods, avoiding the mine tunnel collapse problem caused by the drilling process of the drilling structure.

[0022] 2. By utilizing multiple upper support legs formed by the second fixed seat and the horizontal upper connecting rod and the vertical upper stabilizing beam, and multiple lower support legs formed by the first fixed seat and the horizontal lower connecting rod and the vertical lower stabilizing beam, combined with the sleeved connection between the lower moving mechanism and the upper supporting mechanism, the support effect on the moving vehicle body is effectively guaranteed, and the safety is improved.

[0025] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0026] This invention discloses a safe continuous drilling device for metal mining.

[0027] Reference Figure 1 , Figure 2 , Figure 3 A safe continuous drilling device for metal mining includes a mobile vehicle body 1. Track mechanisms 2 are provided on both sides of the bottom of the mobile vehicle body 1. The rod of the track mechanism 2 is located inside the mobile vehicle body 1 and connected to the motor end. As the track inside the track mechanism 2 rotates, it drives the mobile vehicle body 1 to move in the mine tunnel. The mobile vehicle body 1 is fixed with a driver's cab 3 that is easy for personnel to operate. A support shell 4 is fixed on the top of the mobile vehicle body 1 on the outer surface of the driver's cab 3. The support shell 4 partially covers the driver's cab 3 to form a cover and prevent the falling rocks in the mine tunnel from causing personnel injury. A drilling structure 7 is provided at the front end of the mobile vehicle body 1. The drilling structure 7 is composed of a drill bit, a telescopic structure, a rotating mechanism, etc. As the mobile vehicle body 1 moves, the drilling structure 7 is driven to drill into the front end of the mine tunnel. A collection bucket 8 is fixed at the bottom of the drilling structure 7 at the front end of the mobile vehicle body 1. The end of the collection bucket 8 facing the mine tunnel is provided with an inclined surface to facilitate the shoveling of fallen ore into the bucket. Guide wheels 9 are rotatably provided on both sides of the upper surface of the collection bucket 8, and a feed chute 10 is opened downward on the surface of the collection bucket 8 between the two guide wheels 9. As the guide wheels 9 rotate, the ore is brought into the feed chute 10. The front end of the mobile vehicle body 1 is provided with a discharge port 14 through the feed trough 10. The ore is driven by the movement of the mobile vehicle body 1 and the rotation of the guide wheel 9, and enters the discharge port 14 from the feed trough 10. A conveyor belt structure is provided at the rear end of the mobile vehicle body 1 at the discharge port 14, so as to transport the ore to the outside.

[0028] Reference Figure 5 , Figure 6 , Figure 7 The lower moving mechanism 5 includes two lower support legs 51 arranged in pairs on both sides of the moving vehicle body 1 (the lower support legs 51 are composed of a base at the bottom and a push rod structure at the top). The top of each of the four lower support legs 51 is screwed with a first fixed seat 52, and the top of each of the four first fixed seats 52 is horizontally inserted with a lower connecting rod 53 in pairs. A crossbar is fixed in the middle of the opposite side of the two lower connecting rods 53. An interactive plate 55 is fixed on the lower end face of the crossbar. The interactive plate 55 is T-shaped and extends horizontally in the same direction as the lower connecting rod 53. The extended end of the interactive plate 55 is outside the coverage area of ​​the lower connecting rod 53 and is fixed with a bending surface 56. The bending surface 56 is made of high-strength steel and has a certain curvature angle on its surface. A partition groove 57 is provided at the center of the lower end face of the interactive panel 55, and a first pressing block 58 is fixedly provided at the center of the top of the partition groove 57. The first pressing block 58 is a trapezoid with both sides contracting inward. At the same time, a limiting groove 11 is provided at the center of the upper end face of the support housing 4. The groove 11 has the same T-shape as the interactive panel 55, and the interactive panel 55 is located in the limiting groove 11 and moves through it. A lower rod sensor 13 is fixedly provided in the middle of the limiting groove 11. The lower rod sensor 13 is connected to the push rod structure in the lower support leg 51. When the interactive panel 55 is fully inserted into the limiting groove 11, the limiting groove 11, the partition groove 57, and the first pressing block 58 are connected to form two isolation chambers. At this time, the lower rod sensor 13 is located in one of the chambers. As the moving vehicle body 1 moves, the lower rod sensor 13 is pressed against the first pressing block 58. During the process of the lower rod sensor 13 entering the other chamber, it controls the lower support leg 51 to retract and extend. Lower stabilizing beams 54 are installed through each pair of the four first fixed seats 52 on the side surface adjacent to the lower connecting rods 53. The lower stabilizing beams 54 form an integral support frame with the lower connecting rods 53 through the first fixed seats 52, thereby supporting and stabilizing the inner wall of the mine tunnel. A stop sensor 59 is fixedly installed on the side surface of one of the lower stabilizing beams 54 near the bending surface 56. The lower end face of the lower stabilizing beam 54 is slotted upward on the side of the stop sensor 59, and an extension sensor 510 is fixedly installed in the slot. The extension sensor 510, the stop sensor 59, and the lower rod sensor 13 can all be configured as pressure sensors. A second extrusion block 12 is protruding from the upper end face of the moving vehicle body 1 on the side of the limiting groove 11, and the bottom of the extension sensor 510 is in contact with the second extrusion block 12.

[0029] It should be noted that the upper support mechanism 6 is stacked on top of the lower moving mechanism 5 and is provided with electric push rods 68 that are respectively connected to the rotating seat 67 and the lower connecting rod 53, forming a connection between the upper support mechanism 6 and the lower moving mechanism 5. First, the movement of the mobile vehicle body 1 causes the first pressing block 58 to press against the lower rod sensor 13, thereby controlling the retraction end of the lower support leg 51 to retract. As the lower support leg 51 retracts, the support of the lower support leg 51 and the lower connecting rod 53 on the mine tunnel is canceled. At this time, the mobile vehicle body 1 completes the displacement and stops moving, and cooperates with the drilling structure 7 to drill into the inner wall of the mine tunnel. At the same time, the movement of the mobile vehicle body 1 causes the second pressing block 12 to press against the extension sensor 510, thereby controlling the electric push rod 68 to extend. At this time, the electric push rod 68 pushes the lower connecting rod 53, which is in the unsupported state, so that the lower connecting rod 53 moves towards the mobile vehicle body 1, thereby causing the first pressing block 58 and the second pressing block 12 to press against the lower rod sensor 13 and the extension sensor 510 again, thereby causing the lower support leg 51 to extend and the electric push rod 68 to retract, thus completing the movement and support action of the lower support leg 51.

[0030] Reference Figure 2 , Figure 4 , Figure 7 The upper support mechanism 6 includes upper supports 61 located outside the four lower supports 51. The structure of the upper supports 61 is the same as that of the lower supports 51. A second fixing seat 62 is screwed to the top of each of the four upper supports 61. Upper connecting rods 63 are horizontally inserted into the top of each of the four second fixing seats 62. Fixed main plates 64 are inserted into the middle of the upper connecting rods 63 on both sides. Fixed auxiliary plates 65 are inserted into the outer sides and between the two fixed main plates 64 of the upper connecting rods 63. The fixed main plates 64 are responsible for connecting the upper connecting rods 63 located in the middle position as a whole. The fixed auxiliary plates 65 are responsible for connecting the upper connecting rods 63 located on both sides to the middle position, thereby improving the stability of the upper connecting rods 63 (adjustable force sensors can be installed at the bottom of the lower supports 51 and the upper supports 61 to adjust the support force according to the actual conditions of the mine). One of the fixed main plates 64 near the bending surface 56 extends downwards, and an upper rod sensor 611 is fixedly installed on the side of the surface facing the bending surface 56. The upper rod sensor 611 is of the same type as the stop sensor 59, and the upper rod sensor 611 is aligned with the center of the bending surface 56. A rotating seat 67 is provided at the bottom of the fixed main plate 64 on the other side of the upper rod sensor 611. The fixed end of the electric push rod 68 is located on the side of the rotating seat 67 away from the fixed main plate 64, and the electric push rod 68 is rotatably connected to the rotating seat 67. The telescopic end of the electric push rod 68 extends laterally, and a connecting seat 69 is rotatably connected to the extended end. The end of the connecting seat 69 away from the electric push rod 68 is fixedly connected to the middle of the crossbar of the lower connecting rod 53, thereby forming a lateral installation of the electric push rod 68. Both ends of the electric push rod 68 are rotatably connected to avoid misalignment with the lower connecting rod 53 and the upper connecting rod 63 due to the extension of the electric push rod 68. On the side of the four second fixed seats 62 adjacent to the upper connecting rods 63, upper stabilizing beams 66 are inserted in pairs to form a fixed structure at the bottom of the multiple upper connecting rods 63, thereby improving the stability of the frame formed by the upper connecting rods 63. A pressing plate 610 is provided extending downward from the bottom of the rotating seat 67. The pressing plate 610 is aligned with the center of the stop sensor 59. Both the upper stabilizing beams 66 and the lower stabilizing beams 54 are made of Q345B alloy steel with a tensile strength of 500MPa, thereby improving the connection stability between the upper connecting rods 63 and the lower connecting rods 53.

[0031] Reference Figures 1 to 8 The method of using this invention is as follows: S01. First, the mobile vehicle body 1 needs to be moved to the entrance of the mine tunnel to be drilled, and the lower moving mechanism 5 and the upper support mechanism 6 are arranged on the outer surface of the mobile vehicle body 1 and unfolded. At this time, the push rods of the lower support leg 51 and the upper support leg 61 are in the extended state, pushing the bottom base and the top connecting rod 63 to form a support in the mine tunnel. As the moving vehicle body 1 moves, the lower rod sensor 13 moves laterally in sync. The lower rod sensor 13 in the limiting groove 11 abuts against the bottom of the first pressing block 58, causing the lower rod sensor 13 to control the push rod in the lower support leg 51 to retract. The lower support leg 51 retracts and cancels the support state. At this time, as the moving vehicle body 1 continues to move, it drives the second pressing block 12 to move. When the second pressing block 12 abuts against the bottom of the extension sensor 510, the extension sensor 510 controls the output end of the electric push rod 68 to extend outward. The electric push rod 68 extends and pushes the crossbar between the lower connecting rods 53, so that the lower connecting rod 53 moves as a whole with the direction of the moving vehicle body 1. S02. During the movement of the lower connecting rod 53, the interactive plate 55 moves synchronously, which in turn causes the interactive plate 55 to move the first extrusion block 58 along the limiting groove 11, thereby extruding it again against the lower rod sensor 13. The lower rod sensor 13 is extruded and the lower support leg 51 extends, so that the bottom of the lower support leg 51 re-abuts against the inner wall of the mine tunnel, thereby restoring the support state of the lower connecting rod 53 and completing the displacement. During the movement of the lower connecting rod 53, the lower stabilizing beam 54 moves synchronously through the connection relationship of the first fixed seat 52. As the lower stabilizing beam 54 moves, it causes the extension sensor 510 to be squeezed again by the second compression block 12. The extension sensor 510 is squeezed and the electric push rod 68 retracts. At this time, the extension end of the electric push rod 68 is affected by the fixed state of the lower connecting rod 53, forming an interaction force that applies a pulling force to the rotating seat 67. The pulling force is then transmitted to the upper support leg 61 through the rotating seat 67 (the distance of extension and retraction of the lower support leg 51 and the electric push rod 68 is fixed each time, and this distance can be manually adjusted according to the actual mine environment). S03. As the electric actuator 68 retracts, it drives the lower connecting rod 53 to move, causing the lower connecting rod 53 to move the interactive plate 55. The interactive plate 55 then causes the bending surface 56 to come into contact with the upper rod sensor 611. The upper rod sensor 611 is compressed and controls the push rod inside the upper support leg 61 to retract. Subsequently, the upper support leg 61 is released from its supporting state. At this time, the upper connecting rod 63 is driven by the retraction force of the electric actuator 68, thus moving towards the lower connecting rod 53. The movement of the upper connecting rod 63 drives the fixed main plate 64 to move, causing the fixed main plate 64 to drive the pressing plate 610 to come into contact with the stop sensor 59. The stop sensor 59 is compressed and controls the electric actuator 68 to stop running. This completes the stepping action of the lower support leg 51 and the upper support leg 61 (moving synchronously with the moving vehicle body 1). And through the overall support state of the lower connecting rod 53 and the upper connecting rod 63, the support of the inner wall of the mine tunnel is completed.

For those skilled in the art, the present invention can have various modifications and variations.
