Technical Field

[0001] This invention belongs to the field of subsidence pit repair technology, specifically relating to a subsidence pit repair device and repair method used in metal mining. Background Technology

[0002] A subsidence pit is a geological phenomenon caused by the mining of underground ore or the construction of underground projects, which causes the area to collapse. Surface subsidence refers to the downward collapse of surface rock and soil due to human factors, forming a pit at the bottom.

[0003] With the continuous exploitation of metal mines, subsidence pits are constantly forming on the ground, making it easy for ore transport vehicles to encounter danger while driving. Therefore, these pits need to be repaired. Traditional repair methods rely on manual labor, which greatly increases the intensity of manual labor and has low efficiency and poor results. Summary of the Invention

[0004] The purpose of this invention is to address the problem that the continuous mining of metal mines leads to the formation of subsidence pits on the mine surface, which poses a risk to ore transport vehicles. Traditional methods of repairing these pits rely on manual labor, which is labor-intensive, inefficient, and ineffective. Therefore, this invention proposes a subsidence pit repair device and method for metal mines.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] In a preferred embodiment of the present invention, the heat dissipation assembly includes a heat dissipation mesh, connecting columns, a first fan blade, a second fan blade, and a second belt. The heat dissipation mesh is fixedly embedded in the side wall of the ramming machine module housing near the first reciprocating screw.

The other end of the connecting plate is fixedly connected to the top end of the limiting pin.

[0015] A method for repairing subsidence pits in metal mines, which utilizes the aforementioned equipment for repairing subsidence pits in metal mines, specifically includes the following steps:

[0016] S1. First, fill the sinkhole with soil, then turn on the motor. The motor's power output shaft drives the first reciprocating screw to rotate. The first reciprocating screw drives the first pulley to rotate. The first pulley drives the second pulley to rotate through the first belt. The second pulley drives the second reciprocating screw to rotate.

[0017] S2. The first reciprocating screw and the second reciprocating screw are respectively threaded to the connecting ring on it. When the first reciprocating screw and the second reciprocating screw rotate, they drive the connecting ring to move on its outer wall. The connecting ring drives the connecting block to move. The connecting block drives the scraper connecting plate to move through the insert rod. The scraper connecting plate drives the scraper plate to move, so that the filled soil is leveled with the surface of the collapse pit. Then the ramming machine module is opened.

[0018] S3. While the first reciprocating screw rotates, it drives the drive bevel gear to rotate. The drive bevel gear meshes with the first bevel gear at the bottom of the transmission rod, so that the transmission rod rotates synchronously. The first bevel gear at the top of the transmission rod meshes with the second bevel gear. The second bevel gear drives the fourth pulley to rotate, and the fourth pulley drives the first fan blade to rotate.

[0019] S4. The fourth pulley drives the third pulley to rotate via the second belt, and the third pulley drives the second fan blade to rotate, forming an exhaust air field inside the casing of the ramming machine module.

[0020] S5. To replace the old scraper blade with another type of scraper blade, rotate the turntable. The turntable drives the gear to rotate, and the gear meshes with the toothed rack. The toothed rack moves synchronously, and the toothed rack drives the extension plate to move. The extension plate drives the limit pin to move through the connecting plate. When the limit pin moves upward, the bottom of the limit pin leaves the positioning hole on the corresponding side of the insertion rod. Then, the scraper connecting plate and the scraper blade can be removed. Then, insert the new scraper blade or other type of scraper blade, and insert the insertion rods at both ends of the scraper connecting plate into the horizontal slots on the corresponding side. Then, rotate the turntable in the opposite direction. The limit pin moves downward, and the bottom of the limit pin inserts into the positioning hole on the corresponding side of the insertion rod.

[0021] Compared with the prior art, the present invention has the following technical effects:

[0022] 1. This invention, through a scraper assembly, first fills the subsidence pit with soil, then turns on the motor. The motor's power output shaft drives the first reciprocating screw to rotate, which in turn drives the first pulley to rotate. The first pulley, via a first belt, drives the second pulley to rotate, which in turn drives the second reciprocating screw to rotate. The first and second reciprocating screws are threadedly connected to their respective connecting rings. Simultaneously, the rotation of the first and second reciprocating screws causes the connecting rings to move on their outer walls. The connecting rings then drive the connecting block to move, which in turn drives the scraper connecting plate to move via a rod. The scraper connecting plate then drives the scraper plate to move, leveling the filled soil with the surface of the subsidence pit. Finally, the ramming machine module is activated, and the ramming machine within the module compacts the soil. This design effectively achieves mechanical repair of subsidence pits, eliminating the need for traditional manual methods, significantly reducing labor intensity, improving the efficiency of subsidence pit repair, and demonstrating excellent performance.

[0023] 2. This invention utilizes a heat dissipation assembly. The rotation of the first reciprocating screw simultaneously drives the rotation of the drive bevel gear. The drive bevel gear meshes with the first bevel gear at the bottom of the transmission rod, causing the transmission rod to rotate synchronously. The first bevel gear at the top of the transmission rod meshes with the second bevel gear. The second bevel gear drives the fourth pulley to rotate, which in turn drives the first fan blade to rotate. The fourth pulley, via the second belt, drives the third pulley to rotate, which in turn drives the second fan blade to rotate. This creates an exhaust airflow inside the ramming machine module's outer shell. The heat generated during ramming is dissipated through the heat dissipation mesh. This design effectively removes heat from inside the ramming machine module's outer shell to the outside through the exhaust airflow generated by the fan blades, lowering the internal temperature and preventing it from rising. This significantly extends the service life of the ramming machine and results in excellent performance.

[0024] 3. This invention features a quick-release assembly. Rotating the turntable causes the gear to rotate, which meshes with the toothed rack. The toothed rack moves synchronously, driving the extension plate to move. The extension plate, through a connecting plate, moves the limiting pin, causing the limiting pin to move out of the positioning hole on the insertion rod. This design effectively allows for the replacement of the scraper, enabling the replacement of different types of scrapers for different types of subsidence pit repair operations. This greatly increases the practicality of the repair equipment and improves its performance. Attached Figure Description

A motor 21 is fixedly mounted on the outer wall of one end of the left screw housing 210, and the power output shaft of the motor 21 is fixedly connected to one end of the first reciprocating screw 22. A first pulley 24 is fixedly mounted on the other end of the first reciprocating screw 22, and a second pulley 25 is fixedly mounted on the end of the second reciprocating screw 23 near the first pulley 24. A first belt 26 is sleeved on the first pulley 24 and the second pulley 25. When the motor 21 rotates, it drives the first reciprocating screw 22 to rotate, which in turn drives the first pulley 24 to rotate. The first pulley 24 simultaneously drives the first belt 26 to rotate, which in turn drives the second pulley 25 to rotate. As a result, the second reciprocating screw 23 also rotates together with the first reciprocating screw 22.

[0039] Both the first reciprocating screw 22 and the second reciprocating screw 23 are fitted with connecting rings 212 via threaded engagement. The left connecting ring 212 is screwed onto the first reciprocating screw 22, and the right connecting ring 212 is screwed onto the second reciprocating screw 23. Connecting blocks 213 are fixedly installed on the right side of the left connecting ring 212 and the left side of the right connecting ring 212. Figure 2 , Figure 3 and Figure 4 As shown, insert rods 214 are fixedly installed on the outer walls of both the left and right sides of the scraping connecting plate 27. In this embodiment, the connecting ring 212 passes through the stroke groove 211 on the corresponding side of the lead screw housing 210 and can move along the stroke groove 211. The insert rod 214 on the left side of the scraping connecting plate 27 is set on the connecting block 213 on the left side, and the insert rod 214 on the right side is set on the connecting block 213 on the right side. A scraping plate 28 is fixedly installed on the bottom surface of the scraping connecting plate 27. The scraping connecting plate 27 is perpendicular to the first reciprocating lead screw 22.

[0040] The structure of the damping component is as follows Figure 5As shown, the damping assembly 3 includes a damping plate 31, fixing nails 32, telescopic rods 33, and damping springs 34. The damping plate 31 is located below the base plate 29 and parallel to the base plate 29. Multiple telescopic rods 33 are evenly distributed between the base plate 29 and the damping plate 31. Each telescopic rod 33 consists of at least two inserted tube sections, and adjacent tube sections can slide relative to each other axially. The top end of the telescopic rod 33 is fixedly connected to the bottom surface of the base plate 29, and the bottom end of the telescopic rod 33 is fixedly connected to the top surface of the damping plate 31. Each telescopic rod 33 is fitted with a damping spring 34. One end of the damping spring 34 presses against the bottom surface of the base plate 29, and the other end of the damping spring 34 presses against the damping plate 31. Multiple vertical fixing nails 32 are evenly distributed on the bottom surface of the damping plate 31.

[0041] The heat dissipation assembly 4 includes a heat dissipation mesh 41, a connecting column 43, a first fan blade 44, a second fan blade 47, a second belt 45, a mounting plate 49, and a transmission rod 48, as shown below. Figure 6 and Figure 7As shown. The heat dissipation mesh 41 is fixedly embedded in the side wall of the ramming machine module housing 1. In this embodiment, the side wall of the ramming machine module housing 1 is provided with an elongated hole, and the heat dissipation mesh 41 is fixedly embedded in the elongated hole. At least two fixed circular plates 42 are fixedly installed on the inner side wall of the heat dissipation mesh 41. Each fixed circular plate 42 is correspondingly installed with a connecting post 43. One end of the connecting post 43 is rotatably connected to the fixed circular plate 42. The other end of the connecting post 43 near the end of the first reciprocating screw 22 is fixedly connected to one side of the central shaft of the first fan blade 44.

Mounting plate 49 is horizontally fixedly installed on the bottom of the inner wall of the ramming machine module housing 1. Transmission rod 48 passes vertically through mounting plate 49 and rotates with mounting plate 49. First bevel gear 411 is fixedly installed at both ends of transmission rod 48. Second bevel gear 412 is fixedly installed at the other end of the central shaft of first fan blade 44. Drive bevel gear 410 is fixedly installed at one end of first reciprocating screw 22. Second bevel gear 412 meshes with first bevel gear 411 at the top of transmission rod 48. Drive bevel gear 410 meshes with first bevel gear 411 at the bottom of transmission rod 48. The rotation of the first reciprocating screw 22 simultaneously drives the drive bevel gear 410 to rotate. The drive bevel gear 410 meshes with the first bevel gear 411 at the bottom of the transmission rod 48, causing the transmission rod 48 to rotate synchronously. The first bevel gear 411 at the top of the transmission rod 48 meshes with the second bevel gear 412. The second bevel gear 412 drives the fourth pulley 413 to rotate, which in turn drives the first fan blade 44 to rotate. The fourth pulley 413, through the second belt 45 and the third pulley 46, drives the second fan blade 47 to rotate, generating an exhaust airflow inside the ramming machine module housing 1. This exhaust airflow removes the heat generated by the ramming machine and some of the dust through the heat dissipation mesh 41. The ramming machine module and the ramming machine within it are existing technologies and will not be described further.

[0042] Quick-release assembly 5 includes a limit pin 56, a gear 52, a toothed rack 53, an extension plate 54, and a connecting plate 55, as follows: Figure 3 and Figure 4As shown. A horizontal slot 57 is provided on the connecting block 213, and a positioning hole 58 is provided on the insert rod 214. The insert rods 214 at both ends of the scraper connecting plate 27 are inserted into the horizontal slots 57 on the corresponding side of the connecting block 213. A guide hole is vertically provided on the connecting block 213. The guide hole is located above the positioning hole 58. The top end of the guide hole is flush with the top surface of the connecting block 213, and the bottom end of the guide hole communicates with the positioning hole 58. A limiting pin 56 is vertically inserted into the guide hole on the corresponding side and slides with the guide hole. The bottom end of the limiting pin 56 is inserted into the positioning hole 58 on the insert rod 214 on the corresponding side. Gear 52 is mounted on the outer wall of connecting block 213 and rotates in cooperation with connecting block 213. Toothed rack 53 is mounted vertically on the outer wall of connecting block 213 and slides in cooperation with the outer wall of connecting block 213 in the vertical direction. Gear 52 and toothed rack 53 are meshed together. Turntable 51 is fixedly mounted on the outer wall of gear 52. Extension plate 54 and connecting plate 55 are both horizontally arranged. The top end of toothed rack 53 is fixedly connected to one end of extension plate 54. The other end of extension plate 54 is fixedly connected to one end of connecting plate 55. The other end of connecting plate 55 is fixedly connected to the top end of limit pin 56. Rotating the turntable 51 causes the gear 52 to rotate on one side of the connecting block 213. The gear 52 meshes with the toothed rack 53, and the toothed rack 53 moves synchronously. The toothed rack 53 moves upward, which in turn causes the extension plate 54 to move upward. The extension plate 54 moves upward through the connecting plate 55, causing the limit pin 56 to move upward, so that the limit pin 56 moves out of the positioning hole 58 on the insertion rod 214.

[0043] A method for repairing subsidence pits in metal mines, which utilizes the aforementioned equipment for repairing subsidence pits in metal mines, specifically includes the following steps:

[0044] S1. First, fill the sinkhole with soil, then turn on the motor 21. The power output shaft of the motor 21 drives the first reciprocating screw 22 to rotate. The first reciprocating screw 22 drives the first pulley 24 to rotate. The first pulley 24 drives the second pulley 25 to rotate through the first belt 26. The second pulley 25 drives the second reciprocating screw 23 to rotate, thus realizing that the second reciprocating screw 23 and the first reciprocating screw 22 rotate together.

[0045] S2, the first reciprocating screw 22 and the second reciprocating screw 23 are respectively threaded to the connecting ring 212 on them. When the first reciprocating screw 22 and the second reciprocating screw 23 rotate, they drive the connecting ring 212 to move on its outer wall. The connecting ring 212 drives the connecting block 213 to move. The connecting block 213 drives the scraper connecting plate 27 to move through the insert rod 214. The scraper connecting plate 27 drives the scraper plate 28 to move, scraping the filled soil and leveling it with the surface of the collapse pit. Then the ramming machine module is turned on, and the ramming machine is started to ram the soil and continuously compact the filled soil.

[0046] S3. When the first reciprocating screw 22 rotates, it drives the drive bevel gear 410 to rotate. The drive bevel gear 410 meshes with the first bevel gear 411 at the bottom of the transmission rod 48, so that the transmission rod 48 rotates synchronously. The first bevel gear 411 at the top of the transmission rod 48 meshes with the second bevel gear 412. The second bevel gear 412 drives the fourth pulley 413 to rotate, and the fourth pulley 413 drives the first fan blade 44 to rotate.

[0047] S4. The fourth pulley 413 drives the third pulley 46 to rotate via the second belt 45. The third pulley 46 drives the second fan blade 47 to rotate, generating an exhaust air field inside the outer shell 1 of the ramming machine module. This exhaust air field discharges the soil generated by the ramming machine through the heat dissipation net 41.

[0048] S5. To replace the old scraper blade 28 or a scraper blade 28 of another model, rotate the turntable 51. The turntable 51 drives the gear 52 to rotate. The gear 52 meshes with the toothed rack 53, and the toothed rack 53 moves synchronously. The toothed rack 53 drives the extension plate 54 to move. The extension plate 54 drives the limit pin 56 to move through the connecting plate 55. When the limit pin 56 moves upward, the bottom of the limit pin 56 leaves the positioning hole 58 on the corresponding side of the insertion rod 214. Then, the scraper connecting plate 27 and the scraper blade 28 can be removed. Then, replace it with a new or other model of scraper blade 28. Then, insert the insertion rods 214 at both ends of the scraper connecting plate 27 into the horizontal slots 57 on the corresponding side. Then, rotate the turntable 51 in the opposite direction. The limit pin 56 moves downward, and the bottom of the limit pin 56 inserts into the positioning hole 58 on the corresponding side of the insertion rod 214.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
