An automatic mine cover-up machine

Abstract

This invention discloses an automatic mine jacking machine, relating to the field of jacking machine technology. It includes a tracked conveyor vehicle with a connecting platform at its top. A fixing frame, grippers, a conveyor arm, a rotary support device, a swing-lock clamping mechanism, and double-sided connecting supports are mounted on the top of the connecting platform. By incorporating the rotary support device, when the gripper moves towards the conveyor arm, and the rectangular support rod contacts the conveyor arm, the gripper continues to move, sliding relative to the rectangular support rod. This causes the rectangular support rod to push the connecting plate, rotating the rotary support blocks towards the inside of the conveyor arm. When the gripper abuts against the outer wall of the conveyor arm, the two rotary support blocks adhere to the outer wall, thus clamping the conveyor arm tightly. Simultaneously, the rotary support blocks support the bottom of the conveyor arm, increasing the gripping force and making the conveyor arm more stable, thereby preventing it from slipping during lifting.

Description

Technical Field

[0001] This invention relates to the field of shed-recovery machine technology, specifically an automatic shed-recovery machine for mining. Background Technology

[0002] The support system for coal mine tunneling roadways adopts a combination of anchor mesh spraying, cable beams, and anchor cables. Cable beams are usually made of U25 and U29 steel, and each cable beam weighs about 100 kilograms. Therefore, a cable beam installation machine is required to assist in the installation process.

[0003] Existing automatic mine rigging machines typically use hydraulic cylinders to drive a lifting grabber to clamp the conveyor arm used for lifting cable beams. The lifting equipment then raises the entire conveyor arm to transport the cable beam to the designated position. However, because the cable beam itself has a significant weight acting on the conveyor arm, and the clamping force of the lifting grabber only acts on the side of the conveyor arm, the conveyor arm is prone to slipping during the lifting process, thus affecting the installation of the cable beam. To address this issue, we provide an automatic mine rigging machine to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that when the lifting gripper used in an automatic shed-recovery machine clamps the side of the conveyor arm, the conveyor arm tends to slip during the lifting process due to the heavy weight of the cable beam itself. Therefore, this invention provides an automatic shed-recovery machine for mining.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic mine shed repair machine, comprising a tracked conveyor vehicle, a connecting platform at the top of the tracked conveyor vehicle, a fixed frame mounted at the top of the connecting platform, a first hydraulic cylinder rotatably connected to the inner side of the fixed frame, a hinge rotatably connected to the output end of the first hydraulic cylinder, a lifting arm rotatably connected to the inner side of the fixed frame, a fixed column fixedly connected to the inner side of the lifting arm, the outer wall of the fixed column rotatably connected to the hinge, and a second hydraulic cylinder mounted on the inner side of the lifting arm. The output end of the pressure cylinder extends through to the outside of the lifting arm and is fixedly connected to a gripper. A vision recognition module is installed on the outer wall of the second hydraulic cylinder. An inclined end is fixedly connected around the tracked conveyor. A conveying arm is provided on the outer wall of the inclined end. A rectangular frame is installed at one end of the conveying arm. A cable beam is fixedly connected to the bottom of the rectangular frame through a bayonet. A rotary support is provided on one side of the gripper. Two rotary support blocks are provided on one side of the gripper. A swing buckle clamping mechanism is provided on the inner side of each of the two rotary support blocks. Double-sided connecting supports are provided on both sides of the rotary support blocks.

[0006] The rotary support includes a first rotary shaft fixedly connected to the inner side of the rotary support block. The first rotary shaft passes through the inner side of the gripper and is rotatably connected to the gripper. A third torsion spring is installed on the outer walls of both sides of the rotary support block. One end of the third torsion spring is installed inside the gripper. A pressure rotary auxiliary component is provided on the gripper and the inner side of the rotary support block.

[0007] As a further embodiment of the present invention: the pressure-spinning auxiliary component includes a connecting plate fixedly connected to the inner side of the spin support block, a rectangular guide rod fixedly connected to the inner side of the gripper, a rectangular support rod slidably connected to the outer wall of the rectangular guide rod, the bottom end of the rectangular support rod abutting the top end of the connecting plate, and a second spring installed at the bottom end of the rectangular support rod, the bottom end of the second spring being installed inside the gripper.

[0008] As the U-shaped carriage moves away from the pivot block, it drives the second rack to move. When the outer wall teeth of the second rack contact the first spur gear, the first spur gear drives the clamping block to move closer to the outer wall of the conveyor arm through the first rotating shaft. When the pivot block is attached to both sides of the conveyor arm, the clamping block abuts against one end of the conveyor arm, so that the clamping block, pivot block and gripper form a ring clamping structure, thereby further improving the stability of the gripper in fixing the conveyor arm.

[0009] As a further embodiment of the present invention: a rectangular support rod is fixedly connected to one side of the outer wall of the gripper, one end of the rectangular support rod extends through the interior of the lifting arm, and a rectangular groove matching the rectangular support rod is provided on the inner side of the lifting arm.

[0010] As a further embodiment of the present invention: the inner side of the rectangular support rod is provided with a through groove that matches the rectangular guide rod, the rectangular guide rod is disposed inside the through groove, and the inner side of the clamp is provided with a storage groove that matches the rectangular support rod.

[0011] As a further embodiment of the present invention: the double-sided connecting support includes two lateral connecting rods disposed inside the rotating support block. A second rotating shaft is fixedly connected to one outer wall of each lateral connecting rod. One end of the second rotating shaft extends through to the outside of the rotating support block and is rotatably connected to the rotating support block. A second torsion spring is installed on the outer wall of the second rotating shaft. One end of the second torsion spring is installed on the outer wall of the rotating support block. An inwardly recessed inclined groove is provided on the inner side of the gripper. The inclined groove matches the lateral connecting rod. A retraction linkage is provided on the outer wall of the rotating support block.

[0012] When the gripper moves towards the conveyor arm, and the rectangular support rod contacts the conveyor arm, the gripper continues to move, thus sliding relative to the rectangular support rod. This causes the connecting plate to rotate the swivel blocks towards the inside of the conveyor arm via the rectangular support rod. When the gripper abuts against the outer wall of the conveyor arm, the two swivel blocks fit against the outer wall of the conveyor arm, thus gripping the conveyor arm tightly. At the same time, the swivel blocks support the bottom of the conveyor arm, thereby increasing the clamping force of the gripper and making the conveyor arm more stable, thus preventing the conveyor arm from sliding down during the lifting process.

[0013] As a further embodiment of the present invention: the retraction linkage includes a U-shaped connecting frame fixedly connected to the outer wall of one side of the rotating support block, an L-shaped carriage slidably connected to the inner side of the U-shaped connecting frame, a U-shaped carriage fixedly connected to the front end of the L-shaped carriage, a roller rotatably connected to the inner side of the U-shaped carriage, the roller abutting against the outer wall of the side connecting rod, and a first spring fixedly connected to the inner side of the L-shaped carriage, one end of the first spring being fixedly connected to the U-shaped connecting frame.

[0014] As a further embodiment of the present invention: rectangular blocks are fixedly connected to the outer walls of both sides of the L-shaped carriage, and a guide groove matching the rectangular blocks is opened on the inner side of the U-shaped connecting frame. The L-shaped carriage is slidably connected to the U-shaped connecting frame through the rectangular blocks fixedly connected to the outer walls of both sides.

[0015] As a further embodiment of the present invention: the retractable linkage further includes a U-shaped fixing frame fixedly connected to the outer wall of one side of the U-shaped connecting frame, a third rotating shaft rotatably connected to the top of the U-shaped fixing frame, a second spur gear fixedly connected to the outer wall of the third rotating shaft, a first rack and a third rack meshing on both sides of the second spur gear respectively, a rectangular connecting block fixedly connected to one end of the third rack, one end of the rectangular connecting block fixedly connected to the L-shaped slide, a pull rope fixedly connected to one end of the first rack, a second rotating shaft rotatably connected to the inner side of the gripper, a pull rope wound up on the outer wall of the second rotating shaft, a small bevel gear fixedly connected to the top of the second rotating shaft, a large bevel gear fixedly connected to the outer wall of the first rotating shaft, and the large bevel gear meshing with the small bevel gear.

[0016] As a further embodiment of the present invention: the top end of the U-shaped fixing frame is provided with an inwardly recessed T-shaped groove, and the bottom end of the first rack is fixedly connected to a T-shaped guide block, and the first rack is slidably connected to the U-shaped fixing frame through the T-shaped guide block.

[0017] As a further embodiment of the present invention: the swing buckle clamping mechanism includes a fixed seat fixedly connected to the inner side of the rotating support block, a clamping block rotatably connected to the inner side of the fixed seat, a first rotating shaft fixedly connected to the outer walls of both sides of the clamping block, one end of the first rotating shaft passing through to the outside of the fixed seat and rotatably connected to the fixed seat, a first torsion spring installed on the outer wall of the first rotating shaft, one end of the first torsion spring installed on the outer wall of the fixed seat, a first spur gear fixedly connected to the outer wall of the first rotating shaft, and a second rack fixedly connected to both ends of the U-shaped slide, and the second rack meshing with the first spur gear.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By setting up a rotary support device, when the gripper moves towards the conveyor arm, when the rectangular support rod contacts the conveyor arm, the gripper continues to move and slides relative to the rectangular support rod. This causes the rectangular support rod to push the connecting plate, which in turn drives the rotary support block to rotate towards the inside of the conveyor arm. When the gripper abuts against the outer wall of the conveyor arm, the two rotary support blocks fit against the outer wall of the conveyor arm, thus gripping the conveyor arm tightly. At the same time, the rotary support blocks support the bottom of the conveyor arm, thereby increasing the gripping force and making the conveyor arm more stable, thus preventing the conveyor arm from sliding down during the lifting process.

[0020] 2. By setting up double-sided connecting supports and a retraction linkage, when the swivel support block drives the first rotating shaft to rotate, it drives the large bevel gear to rotate, thereby driving the small bevel gear to drive the second rotating shaft to rotate rapidly, winding up the pull rope, thereby pulling the first rack to move, thereby driving the second spur gear to move the third rack in the opposite direction, thereby driving the rectangular connecting block to drive the U-shaped slide to move away from the swivel support block through the L-shaped slide. When the swivel support block is in contact with the outer wall of the conveyor arm, the roller separates from the side connecting rod, so that the second torsion spring is no longer subjected to external force, and drives the side connecting rod to reset through the second rotating shaft, so that the side connecting rod is inserted into the inside of the inclined groove, thereby fixing the swivel support block and the clamp, thereby improving the overall force of the swivel support block, and thus enabling the swivel support block to support the conveyor arm more stably;

[0021] 3. By setting up a swing-lock clamping mechanism, when the U-shaped carriage moves away from the swivel support block, it drives the second rack to move. When the outer wall teeth of the second rack contact the first spur gear, it drives the first spur gear to drive the clamping block to move closer to the outer wall of the conveyor arm through the first rotating shaft. When the swivel support block is attached to both sides of the conveyor arm, the clamping block abuts against one end of the conveyor arm, so that the clamping block, the swivel support block and the gripper form a ring clamping structure, thereby further improving the stability of the gripper fixing the conveyor arm.

[0034] Please see Figures 1-9 In this embodiment of the invention, an automatic mine shed repair machine includes a tracked conveyor 1. A connecting platform 8 is provided at the top of the tracked conveyor 1, and a fixing frame 5 is installed at the top of the connecting platform 8. A first hydraulic cylinder 6 is rotatably connected to the inner side of the fixing frame 5, and a hinge 10 is rotatably connected to the output end of the first hydraulic cylinder 6. A lifting arm 7 is rotatably connected to the inner side of the fixing frame 5, and a fixing column 11 is fixedly connected to the inner side of the lifting arm 7. The outer wall of the fixing column 11 is rotatably connected to the hinge 10. A second hydraulic cylinder 12 is installed on the inner side of the lifting arm 7, and the output end of the second hydraulic cylinder 12... A gripper 14 is fixedly connected to the outside of the lifting arm 7. A vision recognition module 13 is installed on the outer wall of the second hydraulic cylinder 12. An inclined end 9 is fixedly connected around the tracked conveyor 1. A conveyor arm 2 is provided on the outer wall of the inclined end 9. A rectangular frame 3 is installed at one end of the conveyor arm 2. A cable beam 4 is fixedly connected to the bottom of the rectangular frame 3 through a bayonet. A rotary support is provided on one side of the gripper 14. Two rotary support blocks 16 are provided on one side of the gripper 14. A swing buckle clamping mechanism is provided on the inner side of the two rotary support blocks 16. Double-sided connecting supports are provided on both sides of the rotary support blocks 16.

[0035] The rotary support includes a first rotary shaft 38 fixedly connected to the inner side of the rotary support block 16. The first rotary shaft 38 passes through the inner side of the clamp 14 and is rotatably connected to the clamp 14. A third torsion spring 39 is installed on the outer walls of both sides of the rotary support block 16. One end of the third torsion spring 39 is installed inside the clamp 14. The clamp 14 and the inner side of the rotary support block 16 are provided with a pressure rotary auxiliary component.

[0036] The pressure-spinning auxiliary assembly includes a connecting plate 44 fixedly connected to the inner side of the spin support block 16, a rectangular guide rod 49 fixedly connected to the inner side of the clamp 14, a rectangular support rod 15 slidably connected to the outer wall of the rectangular guide rod 49, the bottom end of the rectangular support rod 15 abutting the top end of the connecting plate 44, a second spring 37 installed at the bottom end of the rectangular support rod 15, the bottom end of the second spring 37 installed inside the clamp 14, a rectangular support rod 15 fixedly connected to one side of the outer wall of the clamp 14, one end of the rectangular support rod 15 penetrating into the interior of the lifting arm 7, a rectangular groove matching the rectangular support rod 15 opened on the inner side of the lifting arm 7, a through groove matching the rectangular guide rod 49 opened on the inner side of the rectangular support rod 15, the rectangular guide rod 49 being disposed inside the through groove, and a storage groove matching the rectangular support rod 15 opened on the inner side of the clamp 14.

[0037] In this embodiment: A hydraulically driven pneumatic hammer is fixedly connected to the outer wall of the tracked conveyor 1 via bolts. This hammer is used to strike the cable anchor after the cable beam 4 is installed. When it is necessary to clamp the conveyor arm 2, two second hydraulic cylinders 12 are activated. The output ends of the second hydraulic cylinders 12 drive the clamps 14 to abut against the outer wall of the conveyor arm 2. As the clamps 14 move, they also drive the rectangular support rod 15 to move. The rectangular support rod 15 supports the clamps 14. When the two clamps 14 abut against the outer wall of the conveyor arm 2, the conveyor arm 2 is clamped. When the clamps 14 move towards the conveyor arm 2, and the rectangular support rod 15 contacts the conveyor arm 2, the clamps 14 continue to move, thereby advancing relative to the rectangular support rod 15. The conveyor arm 2 slides, thereby pushing the connecting plate 44 through the rectangular support rod 15 to rotate the swivel block 16 towards the inside of the conveyor arm 2. When the clamp 14 abuts against the outer wall of the conveyor arm 2, the two swivel blocks 16 fit against the outer wall of the conveyor arm 2, thereby holding the conveyor arm 2 tightly. At the same time, the swivel blocks 16 support the bottom of the conveyor arm 2, thereby increasing the clamping force of the clamp 14 and making the conveyor arm 2 more stable. After the conveyor arm 2 is clamped, the first hydraulic cylinder 6 is activated, and the lifting arm 7 is driven by the first hydraulic cylinder to lift the cable beam 4 to the designated position. Then, the hydraulically driven air hammer is used to perform anchoring operations. The installation position of the cable beam 4 is identified by the vision recognition module 13, so that the workers can accurately install the cable beam 4.

[0038] Please refer to this carefully. Figures 4-9The double-sided support includes two lateral connecting rods 18 disposed inside the rotating support block 16. A second rotating shaft 28 is fixedly connected to one outer wall of the lateral connecting rod 18. One end of the second rotating shaft 28 extends through to the outside of the rotating support block 16 and is rotatably connected to the rotating support block 16. A second torsion spring 29 is installed on the outer wall of the second rotating shaft 28, and one end of the second torsion spring 29 is installed on the outer wall of the rotating support block 16. An inwardly recessed inclined groove 19 is provided on the inner side of the clamp 14, and the inclined groove 19 matches the lateral connecting rod 18. A retraction linkage is provided on the outer wall of the rotating support block 16, and the retraction linkage includes a fixed connection. A U-shaped connecting frame 32 is attached to the outer wall of one side of the pivot support block 16. An L-shaped carriage 33 is slidably connected to the inner side of the U-shaped connecting frame 32. A U-shaped carriage 20 is fixedly connected to the front end of the L-shaped carriage 33. A roller 30 is rotatably connected to the inner side of the U-shaped carriage 20. The roller 30 is in contact with the outer wall of the side connecting rod 18. A first spring 36 is fixedly connected to the inner side of the L-shaped carriage 33. One end of the first spring 36 is fixedly connected to the U-shaped connecting frame 32. Rectangular blocks 21 are fixedly connected to the outer walls on both sides of the L-shaped carriage 33. A guide groove matching the rectangular block 21 is provided on the inner side of the U-shaped connecting frame 32. The L-shaped carriage 33 is slidably connected to the U-shaped frame 32 via rectangular blocks 21 fixedly connected to the outer walls on both sides. The retraction linkage also includes a U-shaped fixing frame 45 fixedly connected to one outer wall of the U-shaped frame 32. A third rotating shaft 48 is rotatably connected to the top of the U-shaped fixing frame 45. A second spur gear 47 is fixedly connected to the outer wall of the third rotating shaft 48. A first rack 26 and a third rack 34 are respectively meshed on both sides of the second spur gear 47. A rectangular connecting block 35 is fixedly connected to one end of the third rack 34. One end of the rectangular connecting block 35 is fixedly connected to the L-shaped carriage 33. The first rack 26... One end of 6 is fixedly connected to a pull rope 41. The inner side of the clamp 14 is rotatably connected to a second rotating shaft 40. The pull rope 41 is wound around the outer wall of the second rotating shaft 40. A small bevel gear 43 is fixedly connected to the top of the second rotating shaft 40. A large bevel gear 42 is fixedly connected to the outer wall of the first rotating shaft 38, and the large bevel gear 42 meshes with the small bevel gear 43. The top of the U-shaped fixing frame 45 is provided with an inwardly recessed T-shaped groove 46. A T-shaped guide block 27 is fixedly connected to the bottom of the first rack 26. The first rack 26 is slidably connected to the U-shaped fixing frame 45 through the T-shaped guide block 27.

[0039] In this embodiment: when the swivel support block 16 drives the first swivel shaft 38 to rotate, it also drives the large bevel gear 42 to rotate, thereby driving the small bevel gear 43 to drive the second swivel shaft 40 to rotate rapidly, winding up the pull rope 41, thereby pulling the first rack 26 to move, thereby driving the second spur gear 47 to move the third rack 34 in the opposite direction, thereby driving the U-shaped slide 20 to move away from the swivel support block 16 through the rectangular connecting block 35 via the L-shaped slide 33. When the swivel support block 16 is attached to the outer wall of the conveying arm 2, the roller 30 separates from the side connecting rod 18, so that the second torsion spring 29 is no longer subjected to external force, and drives the side connecting rod 18 to reset through the second rotating shaft 28, so that the side connecting rod 18 is inserted into the interior of the inclined groove 19, thereby fixing the swivel support block 16 and the clamp 14, thereby improving the overall force of the swivel support block 16, and thus enabling the swivel support block 16 to more stably lift the conveying arm 2.

[0040] Please refer to this carefully. Figure 5 The swing buckle clamping mechanism includes a fixed seat 22 fixedly connected to the inner side of the rotating support block 16. A clamping block 17 is rotatably connected to the inner side of the fixed seat 22. A first rotating shaft 23 is fixedly connected to the outer walls of both sides of the clamping block 17. One end of the first rotating shaft 23 extends through to the outside of the fixed seat 22 and is rotatably connected to the fixed seat 22. A first torsion spring 25 is installed on the outer wall of the first rotating shaft 23. One end of the first torsion spring 25 is installed on the outer wall of the fixed seat 22. A first spur gear 24 is fixedly connected to the outer wall of the first rotating shaft 23. A second rack 31 is fixedly connected to both ends of the U-shaped slide 20, and the second rack 31 meshes with the first spur gear 24.

[0041] In this embodiment: when the U-shaped carriage 20 moves away from the pivot block 16, it drives the second rack 31 to move. When the outer wall teeth of the second rack 31 contact the first spur gear 24, the first spur gear 24 is driven to drive the clamping block 17 to move closer to the outer wall of the conveying arm 2 through the first rotating shaft 23. When the pivot block 16 is attached to both sides of the conveying arm 2, the clamping block 17 abuts against one end of the conveying arm 2, so that the clamping block 17, the pivot block 16 and the clamp 14 form a ring clamping structure, thereby further improving the stability of the clamp 14 in fixing the conveying arm 2.

[0042] Working principle: When it is necessary to clamp the conveying arm 2, the two second hydraulic cylinders 12 are activated. The output end of the second hydraulic cylinders 12 drives the clamping gripper 14 to press against the outer wall of the conveying arm 2. While the clamping gripper 14 moves, it drives the rectangular support rod 15 to move. The rectangular support rod 15 supports the clamping gripper 14. When the two clamping grippers 14 press against the outer wall of the conveying arm 2, the conveying arm 2 is clamped.

[0043] When the gripper 14 moves toward the conveyor arm 2, when the rectangular support rod 15 contacts the conveyor arm 2, the gripper 14 continues to move and slides relative to the rectangular support rod 15. This causes the connecting plate 44 to be pushed by the rectangular support rod 15, which in turn drives the rotating support block 16 to rotate toward the inside of the conveyor arm 2. When the gripper 14 abuts against the outer wall of the conveyor arm 2, the two rotating support blocks 16 fit against the outer wall of the conveyor arm 2, thereby holding the conveyor arm 2 tightly. At the same time, the rotating support blocks 16 support the bottom of the conveyor arm 2, thereby increasing the clamping force of the gripper 14 and making the conveyor arm 2 more stably fixed.

[0044] When the swivel support block 16 drives the first swivel shaft 38 to rotate, it drives the large bevel gear 42 to rotate, thereby driving the small bevel gear 43 to drive the second swivel shaft 40 to rotate rapidly, winding up the pull rope 41, thereby pulling the first rack 26 to move, thereby driving the second spur gear 47 to move the third rack 34 in the opposite direction, thereby driving the U-shaped slide 20 to move away from the swivel support block 16 through the rectangular connecting block 35 via the L-shaped slide 33. When the swivel support block 16 is attached to the outer wall of the conveyor arm 2, the roller 30 separates from the side connecting rod 18, so that the second torsion spring 29 is no longer subjected to external force, and drives the side connecting rod 18 to reset through the second swivel shaft 28, so that the side connecting rod 18 is inserted into the interior of the inclined groove 19, thereby fixing the swivel support block 16 and the clamp 14, thereby improving the overall force of the swivel support block 16, and thus enabling the swivel support block 16 to more stably lift the conveyor arm 2;

[0045] As the U-shaped carriage 20 moves away from the pivot block 16, it drives the second rack 31 to move. When the outer wall teeth of the second rack 31 contact the first spur gear 24, the first spur gear 24 is driven to move the clamping block 17 closer to the outer wall of the conveying arm 2 via the first rotating shaft 23. When the pivot block 16 is attached to both sides of the conveying arm 2, the clamping block 17 abuts against one end of the conveying arm 2, so that the clamping block 17, the pivot block 16 and the clamp 14 form a ring clamping structure, thereby further improving the stability of the clamp 14 in fixing the conveying arm 2.

[0046] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
