Description

Technical Field

[0001] This invention relates to the field of coal mining equipment technology, and in particular to coal mining tunneling devices, systems and methods. Background Technology

[0002] Coal mining is generally divided into two categories: open-pit mining and underground mining. Underground mining requires the excavation of a series of shafts and tunnels to reach the underground coal seam and then extract coal. The mining area is the basic unit of underground production, and mine development and the layout of mining area roadways are important components of underground mining. Within a mining area, a series of roadways and several longwall faces are arranged, forming a production system from the longwall faces to the main underground roadways, including transportation, ventilation, power supply, compressed gas, and coal bunkers. Depending on the coal seam occurrence conditions, mining areas can be arranged within a single coal seam or jointly within several adjacent coal seams. To maintain continuous mine production, development work and preparation for new mining areas must be carried out in a timely manner while mining, forming new longwall faces. In addition, development shafts and tunnels connecting various underground mining areas must be arranged to form a comprehensive underground production system.

[0003] With the advancement of technology, underground mining has gradually shifted from traditional explosives-based methods to mechanized mining, making it safer. Underground mining is generally carried out using tunneling machines. The drill bit moves across the mine face, extracting coal that falls onto a collection plate. The coal then enters a conveying system and is transported away. However, the collection plate is usually located at the bottom of the mine, causing coal to scatter everywhere instead of settling effectively. This results in significant coal waste and severe pollution of the mine environment. Summary of the Invention

[0004] The purpose of this invention is to provide a coal mining tunneling device, system, and method to solve the problems mentioned in the background art.

[0022] The coal mining tunneling system, which operates based on the aforementioned coal mining tunneling device, includes a central controller that is electrically connected to the coal mining tunneling device and is used to control the coal mining tunneling device.

[0023] The coal mining tunneling method, based on the aforementioned coal mining tunneling equipment, includes the following steps:

[0024] S1. When the tunneling machine enters the mine to collect coal, the cylinder can be activated to drive the push rod, which in turn pushes the push frame to move. The push frame drives the two support rods to rotate, and the two support rods can open the two moving plates. The two moving plates can drive the two extension plates to unfold, so that the two extension plates can be moved to a position flush with the inner walls on both sides of the mine, thereby achieving the purpose of expanding the area of ​​the collecting plate and enabling the coal excavated by the tunneling drill bit to be fully collected.

[0025] S2. During the movement of the tunneling drill bit, two linkage rods can be moved, and the two linkage rods can pull the aggregate plate to move, so that the aggregate plate can move synchronously with the drill bit, helping the aggregate plate to more fully catch the coal excavated by the tunneling drill bit.

[0026] S3. When the two extension plates move, the two side supports can be moved by the two connecting rods. The side supports move in the four telescopic slots by the four telescopic rods. When the side supports move, they can drive the follower rod to rotate. The follower rod drives the rotating rod to rotate by the connecting shaft. The rotating rod can drive the intermediate shaft to move. The intermediate shaft can drive the movable block to slide in the movable slot. At the same time, the intermediate shaft can drive the shaft block to move. The shaft block drives the mounting strip to move by the top rod. The mounting strip can drive the top support to unfold upward to complete the support.

[0027] S4. The collected coal is transported to the conveying device through the discharge hose, and finally transported out through the conveying device to complete the coal mining.

[0028] The beneficial effects of the coal mining tunneling device, system, and method proposed in this invention are:

[0029] In this invention, by setting up an extension device and a linkage device, when the drilling bit is mining, the drilling bit can drive the collecting plate to move up and down synchronously through the linkage rod, which can fully collect the mined coal and prevent coal from scattering and polluting the mine environment. At the same time, the collecting plate can be unfolded by two extension plates to increase the collection area, which can further fully collect the coal.

[0030] Furthermore, in this invention, by setting up a support device, when the tunneling machine is tunneling, the two side support frames can support the two sides of the mine wall, and the top support frame can support the top wall of the mine, thus achieving effective support for the mine and avoiding accidents such as collapse during tunneling, making the use of the tunneling machine safer.

[0031] Furthermore, in this invention, by setting up a driving device, when the extension plate is unfolded, the two side support frames can be unfolded. The unfolding of the side support frames drives the follower rod to rotate, and the follower rod drives the rotating rod to rotate through the connecting shaft. In turn, the rotating rod drives the top rod to rotate, unfolding the top support frame. This allows the support work to be completed during the mining process, ensuring the safety of the mining work and preventing the mine from collapsing. Attached Figure Description

[0047] Please refer to the attached instruction manual. Figure 1-8 The coal mining tunneling device provided in this embodiment of the invention includes a tunneling machine 1, a tunneling arm 2 installed on the tunneling machine 1, a tunneling drill bit 3 installed on the tunneling arm 2, a conveying device 5 installed inside the tunneling machine 1, a material collection device 4 installed on the tunneling machine 1, the material collection device 4 being located below the tunneling drill bit 3, and two feeding rotating frames 10 installed on the material collection device 4.

[0048] Furthermore, the coal mining tunneling device provided in this embodiment of the invention also includes a linkage device 6, which is connected to the tunneling drill bit 3 and the collecting device 4. The tunneling drill bit 3 drives the collecting device 4 to move synchronously through the linkage device 6. An extension device 7 is installed on the collecting device 4 to expand the collecting area of ​​the collecting device 4. It should be noted that by connecting the collecting device 4 to the tunneling arm 2, the collecting device 4 can move with the movement of the tunneling arm 2. Therefore, when collecting coal collected by the tunneling arm 2, the collecting device 4 can be moved synchronously to the position where the coal falls. In addition, during the coal collection process, coal scattering can be effectively avoided. Furthermore, the extension device 7 is added to the collecting device 4 to further increase the collecting area of ​​the collecting device 4, so that the coal can be fully collected. During the upward movement of the collecting device 4, the mine wall can also be scraped, thus playing a role in actively collecting coal and further increasing the coal collection efficiency.

[0049] Furthermore, the coal mining tunneling device provided in this embodiment of the invention also includes a support device 8. The support device 8 is installed on both sides and the top side of the tunneling machine 1, and is used to support the side walls and top walls of the mine after tunneling. A driving device 9 is installed on the support device 8, and the driving device 9 is connected to the extension device 7. It should be noted that, in this embodiment of the invention, by setting the extension device 7 on the collecting device 4, the area of ​​the collecting device 4 can be expanded to fully collect the coal mined by the tunneling drill bit 3, preventing the coal from scattering on the bottom wall of the mine, thereby ensuring the environment of the mine; at the same time, by setting the support device 8, the inner walls on both sides and the top wall of the coal mine can be effectively supported during the tunneling process of the coal tunneling machine, further ensuring the safety of mining.

[0050] Please refer to the attached instruction manual. Figure 1-4 Furthermore, in this embodiment of the invention, the collecting device 4 includes a collecting plate 401, two feeding rotating frames 10 are rotatably mounted on the top side of the collecting plate 401, and sliding frames 402 are installed on both sides of the collecting plate 401. Two sliding grooves 403 are opened on one side of the tunneling machine 1, and sliding blocks 404 are slidably installed in both sliding grooves 403. The two sliding blocks 404 are respectively installed on both sides of the collecting plate 401, and a buffer spring 405 is installed on the bottom side of the sliding block 404. The bottom end of the buffer spring 405 is installed on the bottom inner wall of the sliding groove 403. It should be noted that the collecting plate 401 slides vertically in the two sliding grooves 403 through the two sliding frames 402, so that the collecting plate 401 can be closely attached to the mine wall, so that there is no gap between the collecting plate 401 and the mine wall. When the collecting plate 401 moves with the tunneling arm 2, it can prevent coal leakage and actively collect coal, thereby achieving the effect of fully collecting coal.

[0051] Please refer to the attached instruction manual. Figure 1-5 More specifically, a discharge hose 406 is connected to the collecting plate 401, and a mounting bracket 407 is installed on both sides of the discharge hose 406. The two mounting brackets 407 are respectively installed on the inner walls of both sides of the conveying device 5. It should be noted that in this embodiment of the invention, the material collection device 4 can move along with the tunneling drill bit 3. When the tunneling drill bit 3 moves, it can drive the material collection plate 401 to move. The movement of the material collection plate 401 drives the two sliding frames 402 to move, and the movement of the sliding frames 402 drives the two sliding blocks 404 to move. The sliding blocks 404 slide in the sliding groove 403, thereby enabling the material collection plate 401 to slide vertically, avoiding tilting and ensuring the collection of coal. At the same time, when the tunneling drill bit 3 moves downward, the material collection plate 401 can drive the sliding blocks 404 to slide down and squeeze the buffer spring 405, so that the material collection plate 401 can move downward with the tunneling drill bit 3. Thus, the buffer spring 405 can ensure that the tunneling arm 2 can tunnel normally without interfering with the coal mining work, further ensuring the full collection of coal.

[0052] It should be emphasized that in other embodiments of the present invention, the collected coal flows out through the discharge hose 406. The discharge hose 406 is a flexible pipe, such as a rubber hose, a corrugated pipe or other pipe, which can help with the discharge without interfering with the movement of the collecting plate 401. The specific choice is best to meet the actual use requirements.

[0053] Please refer to the attached instruction manual. Figure 4 Furthermore, in this embodiment of the invention, the linkage device 6 includes two linkage rods 601. A linkage seat 602 is rotatably mounted on one side of each linkage rod 601. The linkage seat 602 is mounted on the top side of the collecting plate 401. Two linkage shafts 603 are rotatably mounted on the linkage rods 601, and the two linkage shafts 603 are respectively mounted on the tunneling arm 2 and the linkage seat 602. It should be noted that, in this embodiment of the invention, when the tunneling drill bit 3 moves, the two linkage rods 601 can be moved by the two linkage shafts 603. The two linkage rods 601 can also move the two linkage seats 602 by the other two linkage shafts 603. This achieves the purpose of vertically moving the collecting plate 401 during the movement of the tunneling drill bit 3, ensuring sufficient coal collection.

[0054] Please refer to the attached instruction manual. Figure 3-5Furthermore, in this embodiment of the invention, the expansion device 7 includes two expansion plates 701, and a surrounding plate 702 is installed on the top side of both expansion plates 701 and the collecting plate 401. The discharge hose 406 is installed on the surrounding plate 702. Two moving grooves 408 are opened on the bottom side of the collecting plate 401. A moving plate 703 is installed on both expansion plates 701, and the other moving plate 703 is slidably installed in the moving groove 408. Translation grooves 704 are opened on both sides of the inner wall of the moving groove 408. Translation strips 705 are installed on both sides of the moving plate 703, and the two translation strips 705 are slidably installed in the two translation grooves 704 respectively. It should be noted that, in this embodiment of the invention, the extension plate 701 can move within the moving groove 408 via two moving plates 703, while the moving plates 703 move within the two moving grooves 704 via two translation bars 705, allowing the extension plate 701 to slide only horizontally. With the moving plates 703 in place, when the collecting plate 401 collects coal, the moving plates 703 can expand the width of the extension plate 701, thereby allowing the width of the collecting plate 401 to be fully adjusted, enabling the collecting plate 401 to obtain a larger receiving area and fully collect the collected coal. Furthermore, the width of the extension plate 701 is easily adjustable, allowing for full adaptation to mines of different widths, effectively increasing the versatility of the extension plate 701.

[0055] It should be emphasized that the installation of a surrounding plate 702 on the top side of both the expansion plate 701 and the collecting plate 401 can prevent coal from scattering. At the same time, setting the end faces of the expansion plate 701 and the collecting plate 401 as inclined surfaces can better catch the coal.

[0056] Furthermore, please refer to the appendix of the instruction manual. Figure 1-3 In this embodiment of the invention, a cylinder 706 is installed on the bottom side of the collecting plate 401, a push rod 707 is installed at the output end of the cylinder 706, a push frame 708 is installed at the end of the push rod 707, and two spreading rods 709 are rotatably installed on the push frame 708. The two spreading rods 709 are respectively rotatably installed on two moving plates 703.

[0057] More specifically, two expansion shafts 710 are rotatably mounted on the expansion rod 709, and the two expansion shafts 710 are respectively mounted on the moving plate 703 and the push frame 708. It should be noted that, in this embodiment of the invention, after the tunneling machine enters the mine, the position of the two expansion plates 701 can be adjusted according to the inner walls on both sides of the mine. At this time, the cylinder 706 is activated, and the cylinder 706 can push the push rod 707 to move. The push rod 707 drives the push frame 708 to move. The push frame 708 drives the two expansion plates 701 to move through the two expansion rods 709 until the two expansion plates 701 can abut against the inner walls on both sides of the mine, thereby realizing the adjustment of the width of the aggregate plate 401. It can be adapted to mines of different widths, is convenient to use, and has good versatility.

[0058] It should be emphasized that in practical applications, in order to reduce resistance, an auxiliary wheel can be added to the side of the extension plate 701 near the mine wall. Adjusting by cylinder 706 is only one of the rotation adjustment methods. Manual adjustment, motor adjustment, or other adjustment methods can also be used to meet the actual use requirements.

[0059] Please continue to refer to the attached instruction manual. Figure 1-4 In this embodiment of the invention, the support device 8 includes a top support frame 802 and two side support frames 801. Connecting rods 711 are installed on both extension plates 701. The two connecting rods 711 are respectively installed on the two side support frames 801. Four telescopic slots 803 are provided on both sides and the top side of the tunneling machine 1. Telescopic rods 804 are installed at the four corners of the top support frame 802 and the two side support frames 801. The multiple telescopic rods 804 are movably installed in the multiple telescopic slots 803.

[0060] More specifically, multiple casters 805 are installed on the top support frame 802 and the two side support frames 801 to facilitate their smooth movement. It should be noted that in this embodiment of the invention, when the extension plate 701 moves, the connecting rod 711 can drive the side support frames 801 to move as well. Simultaneously, the side support frames 801 can drive the top support frame 802 to unfold, thereby enabling the two side support frames 801 and the top support frame 802 to support the inner walls and top wall of the mine. This allows support work to be completed during mining operations, ensuring the safety of the mining work and preventing mine collapse.

[0061] Furthermore, please refer to the appendix of the instruction manual. Figure 7-8In this embodiment of the invention, the driving device 9 includes a follower rod 901, which is movably mounted on the side support frame 801. The side support frame 801 has a sliding hole 914, and a sliding shaft 913 is slidably installed in the sliding hole 914. The sliding shaft 913 is rotatably mounted on the follower rod 901. A bearing seat 902 is rotatably mounted on the follower rod 901. The bearing seat 902 is mounted on the side wall of the tunneling machine 1. A connecting shaft 903 is rotatably mounted on the bearing seat 902. The follower rod 901 is sleeved on the connecting shaft 903. A rotating rod 904 is sleeved on the connecting shaft 903. It should be noted that, in this embodiment of the invention, when the side support frame 801 moves, it can drive the follower rod 901 to rotate. The follower rod 901 drives the rotating rod 904 to rotate through the connecting shaft 903, which in turn drives the top rod 909 to rotate, thus unfolding the top support frame 802. The extension device 7 and the support device 8 can be connected through the driving device 9. When the extension plate 701 is adjusted, both the side support frame 801 and the top support frame 802 can be unfolded synchronously, playing a supporting role. Thus, when the tunneling machine 1 is tunneling, it can be protected by the support device 8 synchronously without any delay. Therefore, the protection measures can be fully deployed at the beginning of the tunneling work, ensuring the safety of the tunneling operation at the start of the tunneling work. This ensures the safety of the coal collection work when the tunneling machine 1 is collecting coal.

[0062] Furthermore, please refer to the appendix to the instruction manual. Figure 6-7 In this embodiment of the invention, a movable groove 905 is provided on the top side of the tunneling machine 1, a movable block 906 is slidably installed in the movable groove 905, an intermediate shaft 907 is installed on the top side of the movable block 906, a shaft block 908 is sleeved on the intermediate shaft 907, a top rod 909 is rotatably installed on the shaft block 908, and an installation strip 910 is rotatably installed on the top rod 909. The installation strip 910 is installed on the top support frame 802. A movable hole 912 is provided on the rotating rod 904, the intermediate shaft 907 is installed in the movable hole 912, and two top shafts 911 are rotatably installed on the top rod 909. The two top shafts 911 are respectively installed on the shaft block 908 and the installation strip 910. It should be noted that in this embodiment of the invention, the rotating rod 904 can drive the intermediate shaft 907 to move, the intermediate shaft 907 can drive the movable block 906 to slide in the movable groove 905, and at the same time the intermediate shaft 907 can drive the shaft block 908 to move. The shaft block 908 drives the mounting strip 910 to move through the top rod 909. The mounting strip 910 can drive the top support frame 802 to unfold upward to complete the support. The collected coal is transported to the conveying device 5 through the discharge hose 406, and finally transported out through the conveying device 5 to complete the coal mining.

[0063] This invention also provides a coal mining tunneling system, which is used in accordance with the above-described coal mining tunneling device provided in this invention. The system includes a central controller, which is electrically connected to the coal mining tunneling device and is used to control the device. It should be noted that, in this invention, electrical components such as the cylinder 706 can be connected to the central controller on the original tunneling machine 1, so that the operator can better control the tunneling machine 1 for mining operations.

[0064] This invention also provides a method for tunneling in coal mining, which is carried out using the coal mining tunneling device provided in the above-described embodiments of the invention, and includes the following steps:

[0065] S1. When the tunneling machine 1 enters the mine to collect coal, the cylinder 706 can be activated to drive the push rod 707, which in turn pushes the push frame 708 to move. The push frame 708 drives the two spreading rods 709 to rotate. The two spreading rods 709 can spread the two moving plates 703. The two moving plates 703 can drive the two extension plates 701 to unfold, so that the two extension plates 701 can move to a position flush with the inner walls on both sides of the mine, thereby achieving the purpose of expanding the area of ​​the collecting plate 401, which can fully collect the coal excavated by the tunneling drill bit 3.

[0066] S2. During the movement of the tunneling drill bit 3, it can drive the two linkage rods 601 to move. The two linkage rods 601 can pull the collecting plate 401 to move, so that the collecting plate 401 can move synchronously with the drill bit 3, and help the collecting plate 401 to more fully catch the coal dug out by the tunneling drill bit 3.

[0067] S3. When the two extension plates 701 move, the two side support frames 801 can be moved by the two connecting rods 711. The side support frames 801 move in the four telescopic grooves 803 through the four telescopic rods 804. When the side support frames 801 move, they can drive the follower rod 901 to rotate. The follower rod 901 drives the rotating rod 904 to rotate through the connecting shaft 903. The rotating rod 904 can drive the intermediate shaft 907 to move. The intermediate shaft 907 can drive the movable block 906 to slide in the movable groove 905. At the same time, the intermediate shaft 907 can drive the shaft block 908 to move. The shaft block 908 drives the mounting strip 910 to move through the top rod 909. The mounting strip 910 can drive the top support frame 802 to unfold upward to complete the support.

[0068] S4. The collected coal is transported to the conveying device 5 through the discharge hose 406, and finally transported out through the conveying device 5 to complete the coal mining.

[0069] In summary, the working principle of the coal mining tunneling device provided in this embodiment of the invention is as follows: When the tunneling machine 1 enters the mine to collect coal, the cylinder 706 can be activated, driving the push rod 707, which in turn pushes the push frame 708 to move. The push frame 708 drives the two spreading rods 709 to rotate, and the two spreading rods 709 can spread the two moving plates 703. When the moving plates 703 move, they slide horizontally in the spreading groove 704 through the translation bar 705. The two moving plates 703 can drive the two extension plates 701 to unfold, so that the two extension plates 701 can move to a position flush with the inner walls on both sides of the mine, thereby achieving the purpose of expanding the area of ​​the collecting plate 401 and enabling sufficient collection of the coal excavated by the tunneling drill bit 3.

[0070] Furthermore, during the movement of the tunneling drill bit 3, two linkage shafts 603 can drive two linkage rods 601 to move. The two linkage rods 601 can pull the aggregate plate 401 to move through the other two linkage shafts 603. At the same time, the linkage rods 601 rotate on the two linkage shafts 603, thereby achieving the purpose of the aggregate plate 401 moving synchronously with the drill bit 3, helping the aggregate plate 401 to more fully catch the coal excavated by the tunneling drill bit 3.

[0071] Furthermore, when the two extension plates 701 move, the two side support frames 801 can be moved by the two connecting rods 711. The side support frames 801 move within the four telescopic grooves 803 via four telescopic rods 804. When the side support frames 801 move, the sliding shaft 913 moves through the sliding hole 914. The sliding shaft 913 can drive the follower rod 901 to rotate. The follower rod 901 drives the rotating rod 904 to rotate through the connecting shaft 903. The rotating rod 904 can drive the intermediate shaft 907 to move through the movable hole 912. The intermediate shaft 907 can drive the movable block 906 to slide within the movable groove 905. At the same time, the intermediate shaft 907 can drive the shaft block 908 to move. The shaft block 908 drives the mounting strip 910 to move through the top rod 909. The mounting strip 910 can drive the top support frame 802 to unfold upwards to complete the support. The collected coal is transported to the conveying device 5 through the discharge hose 406 and finally transported out through the conveying device 5, completing the coal mining.
