Description

Technical Field

[0001] This invention relates to the field of mine roadway support technology, and in particular to a continuous support device for mine roadways. Background Technology

[0002] Mining roadways are the tunnels that form and serve the mining face during mining operations. These roadways include the opening cut of the mining face, section haulage tunnels, and section return air tunnels. To ensure that the mining roadways fully meet the needs of ore deposit mining, workers should promptly improve existing construction plans during the pressure support and maintenance construction of mining roadways to minimize unnecessary construction accidents. Furthermore, effective excavation and maintenance of mining roadways ensure that current mining roadway construction better meets the needs of ore deposit mining.

[0003] In iron ore mining, it is common to excavate pits underground along the ore body. Many iron ore deposits are distributed in a belt-like, multi-layered structure. This means that if cracks appear in the walls supporting the mining roadways during the mining process, it can affect the entire roadway and even cause collapses. Once a collapse occurs, it not only obstructs the roadway but also affects mining operations and even threatens the safety of miners. Protective netting laid on the top of the roadway fills the gaps in the supporting structure and effectively prevents falling rocks and other debris, forming a unified support structure. It plays a crucial role in the support work of mining roadways. Currently, however, protective netting on the top of mining roadways is mainly attached between supports, requiring individual installation and attachment. Furthermore, the spacing between supports varies, resulting in loose gaps between some protective netting and the roadway top, reducing its effectiveness in intercepting falling rocks.

[0004] In view of this, the present invention provides a continuous support device for mine roadways to solve the technical problems existing in the prior art. Summary of the Invention

Detailed Implementation

[0028] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0029] Reference Figure 1-8A continuous support device for a mining roadway includes a tracked mobile trolley 1 that travels inside the roadway. A support frame 18 and a mesh belt support frame 16 are fixedly connected to the top of the tracked mobile trolley 1 in sequence. A mesh belt roll 15 is rotatably installed on the top of the mesh belt support frame 16. Multiple support cylinders 20 are installed on the top of the support frame 18. A lifting frame 17 is installed between the tops of the support cylinders 20. A guide plate 19 is installed on the top of the lifting frame 17. A guide cavity that is slidably connected to the guide plate 19 is provided at the bottom of the support frame 18. An inclined support cylinder 2 is hinged between the top of the support frame 18 and the lifting frame 17. A mesh belt laying component is installed inside the lifting frame 17. A mesh belt fixing component is installed on the side of the lifting frame 17.

[0030] The mesh belt laying assembly includes multiple support rollers 9 rotatably mounted on the top of the lifting frame 17, and a drive assembly 13 movably mounted inside the lifting frame 17. A drive roller 11 is mounted on the top of the drive assembly 13, and a drive motor 21 connected to the drive roller 11 is mounted at both ends of the drive assembly 13. A mesh belt laying chain plate 8 is sleeved between the support rollers 9 and the outer side of the drive roller 11.

[0031] The mesh belt fixing assembly includes a fixing plate 4 installed on the side of the lifting frame 17 and a propulsion cylinder 3 installed on the fixing plate 4. A drilling power mechanism 5 is installed on the top of the propulsion cylinder 3. A guide mechanism 6 is installed above the fixing plate 4, and a mesh belt fixing anchor rod 7 is engaged inside the guide mechanism 6. The top of the drilling power mechanism 5 is connected to the bottom of the mesh belt fixing anchor rod 7.

[0032] In this invention, a tracked mobile trolley 1 is installed to travel inside the mining roadway. A protective netting belt, placed on the top of the mining roadway, is mounted on a netting belt support frame 16. After the device moves into the mining roadway, one end of the protective netting belt is unfolded and placed above the netting belt laying chain plate 8. Through the cooperation of the inclined support cylinder 2 and the support cylinder 20, the lifting frame 17 is raised, causing the netting belt laying chain plate 8 to fit against the top of the roadway. The netting belt laying chain plate 8 moves synchronously with the tracked mobile trolley 1, laying the protective netting belt on the top of the roadway during the movement. During the laying process, workers insert the netting belt fixing anchor rod 7 into the guide mechanism 6, and then drive it using the propulsion cylinder 3. Above the drilling power mechanism 5, the bottom end of the mesh belt fixing anchor 7 is embedded in the top of the drilling power mechanism 5, lifting the mesh belt fixing anchor 7 upward and rotating it. The mesh belt fixing anchor 7 is then drilled into the top of the roadway, firmly fixing the protective mesh belt to the top of the roadway. This continuous laying operation uses the mesh belt fixing anchor 7 to anchor the protective mesh belt. The mesh belt fixing anchor 7 and the protective mesh belt form a connection to the roadway support, increasing the support range and maintaining the tension of the protective mesh belt. This improves the tightness of the fit between the protective mesh belt and the top of the roadway, enhances the rockfall prevention effect, and effectively improves the support safety of the roadway top.

[0033] As a further embodiment of the present invention, the lifting frame 17 is provided with a plurality of rectangular grooves 10 in the middle, and the drive assembly 13 is provided with grooves on both sides that are slidably connected to the edges of the rectangular grooves 10. A plurality of spring buffers 14 are installed between the bottom of the drive assembly 13 and the lifting frame 17. In the present invention, the drive roller 11 connecting the bottom of the mesh belt laying chain plate 8 is installed on the drive assembly 13, and the bottom of the drive assembly 13 is pulled downward by the spring buffers 14. Under the sliding cooperation of the rectangular grooves 10 and the grooves, the drive assembly 13 has an up-and-down floating movable connection with the lifting frame 17. When the mesh belt laying chain plate 8 pulls the protective mesh belt to fit against the top of the roadway, the top always maintains downward traction, maintaining the tightness of the fit between the upper end of the mesh belt laying chain plate 8 and the top of the roadway, and preventing the laid protective mesh belt from becoming loose.

[0034] As a further embodiment of the present invention, the outer surface of the mesh belt laying chain plate 8 is provided with multiple protrusions, and the height of the protrusions is the same as the thickness of the protective mesh belt in the mesh belt roll 15. In the present invention, after the protective mesh belt in the mesh belt roll 15 is unrolled, the protrusions on the outer surface of the mesh belt laying chain plate 8 are embedded in the mesh holes of the protective mesh belt, thereby improving the traction and laying effect of the protective mesh belt. When the mesh belt laying chain plate 8 is in contact with the top of the roadway, the protective mesh belt is pressed into the top of the roadway, so that the protective mesh belt is fully in contact with the top of the roadway and the tension of the protective mesh belt is maintained.

[0035] As a further embodiment of the present invention, the drive assembly 13 is internally equipped with a plurality of cleaning mechanisms 12 that cooperate with the drive roller 11. The cleaning mechanism 12 includes a collection frame 121. A plurality of cleaning blocks 122 are provided at the bottom of the collection frame 121. A connecting spring 123 is installed between the bottom of the cleaning block 122 and the collection frame 121. A plurality of inclined elastic columns 124 are provided at the top of the cleaning block 122. In the present invention, the cleaning block 122 and the elastic columns 124 are provided below the mesh belt laying chain plate 8. When the mesh belt laying chain plate 8 rotates, the elastic columns 124 on the surface of the cleaning block 122 are inserted between the protrusions of the mesh belt laying chain plate 8, sweeping the protrusions and debris on the surface of the mesh belt laying chain plate 8 into the collection frame 121, thereby completing the cleaning work on the outer surface of the mesh belt laying chain plate 8 and preventing debris from causing damage to the surface of the protective mesh belt.

[0036] As a further embodiment of the present invention, a ball bearing 125 with a spherical structure is rotatably mounted on the top of the cleaning block 122, and a vibration motor 126 is mounted on the bottom of the cleaning block 122. In the present invention, the cleaning block 122, under the action of the connecting spring 123, adheres to the lower surface of the connecting mesh belt laying chain plate 8, and is connected to the mesh belt laying chain plate 8 by the spherical ball bearing 125. Under the action of the vibration motor 126, the cleaning block 122 and the mesh belt laying chain plate 8 in contact with it vibrate, effectively improving the efficiency of cleaning debris on the surface of the mesh belt laying chain plate 8. Secondly, when the ball bearing 125 encounters a protrusion on the surface of the mesh belt laying chain plate 8, it moves to the periphery, thereby causing the cleaning block 122 to deflect. The elastic column 124 twists and shifts in the gap between the protrusions. Under the action of the vibration and the connecting spring 123, the cleaning block 122 resets, thereby causing the elastic column 124 to continuously insert between the protrusions, further improving the efficiency of cleaning debris on the surface of the mesh belt laying chain plate 8.

[0037] As a further embodiment of the present invention, the mesh belt fixing anchor 7 includes a tray 71 and a nut 72 located at the bottom. The mesh belt fixing anchor 7 also includes a drilling part 75 located at the top. In the present invention, the mesh belt fixing anchor 7 is pre-placed inside the guide mechanism 6. When the drilling power mechanism 5 rises, the nut 72 is embedded in the bottom of the drilling power mechanism 5 and forms a transmission connection. When the drilling power mechanism 5 continues to rise, it drives the mesh belt fixing anchor 7 to rotate. The drilling part 75 located at the top is inserted into the top of the tunnel, and the protective mesh belt is anchored to the top of the tunnel through the tray 71, thus completing the fixing operation of the protective mesh belt.

[0038] As a further embodiment of the present invention, the mesh belt fixing anchor 7 also includes a diaphragm portion 73 located in the middle, and a tensioning disc 74 is engaged between the drilling portion 75 and the diaphragm portion 73. The top of the tensioning disc 74 is provided with a plurality of embedded pins 76. In the present invention, when the mesh belt fixing anchor 7 is screwed into the top of the tunnel to half depth, the embedded pins 76 on the top of the tensioning disc 74 hook the protective mesh belt to rotate and tighten. As the diaphragm portion 73 is inserted into the tensioning disc 74, the embedded pins 76 are embedded into the top of the tunnel, firmly tightening the protective mesh belt, further enhancing the fit between the protective mesh belt and the top of the tunnel, and enhancing the protection strength against falling rocks, etc.

[0039] As a further embodiment of the present invention, the drilling power mechanism 5 includes a drilling connecting plate 52, and a plurality of telescopic extension sleeves 54 are installed on the top of the drilling connecting plate 52. A telescopic coupling is inserted into the inside of the extension sleeve 54. A transmission sleeve 51 adapted to the nut part 72 is provided on the top of the coupling. A drilling motor 53 connected to the coupling is installed at the bottom of the drilling connecting plate 52. In the present invention, when the drilling power mechanism 5 rises, the nut part 72 is embedded in the transmission sleeve 51 to complete the rotational transmission of the mesh belt fixing anchor 7, providing power for the mesh belt fixing anchor 7 to be inserted into the top of the roadway. Furthermore, through the extension sleeves 54 with telescopic function and the setting of the coupling, the mesh belt fixing anchor 7 is specifically inserted into the roadway for uneven parts of the roadway top and the protective mesh belt is fixed.

[0040] As a further embodiment of the present invention, the guide mechanism 6 includes a crossbar 61 fixedly connected to the fixing plate 4, and a plurality of L-shaped extension frames 63 are installed on the top of the crossbar 61. A C-shaped guide cylinder 62 is installed at one end of the extension frame 63, and a magnetic ring 64 is installed in the middle of the guide cylinder 62. In the present invention, when the mesh belt anchor rod 7 is installed, the mesh belt anchor rod 7 is inserted into the guide mechanism 6. Through the magnetic attraction of the magnetic ring 64, the mesh belt anchor rod 7 is suspended in the guide mechanism 6, and the upward movement of the mesh belt anchor rod 7 is guided, thereby improving the stability of the mesh belt anchor rod 7 during the drilling process.

[0041] In use, after the device is moved into the mining roadway, one end of the protective netting is unfolded and placed above the netting laying chain plate 8. Through the cooperation of the inclined support cylinder 2 and the support cylinder 20, the lifting frame 17 is raised, causing the netting laying chain plate 8 to fit against the top of the roadway. The netting laying chain plate 8 moves synchronously with the tracked mobile trolley 1, laying the protective netting on the top of the roadway during the movement. During the laying process, the workers insert the netting fixing anchor 7 into the guide mechanism 6, and drive the drilling mechanism through the propulsion cylinder 3. Above the power mechanism 5, the bottom end of the mesh belt fixing anchor 7 is embedded in the top of the drilling power mechanism 5, and the mesh belt fixing anchor 7 is lifted upward and rotated, drilling the mesh belt fixing anchor 7 into the top of the roadway, firmly fixing the protective mesh belt to the top of the roadway, and continuously laying the mesh belt. The mesh belt fixing anchor 7 is used to anchor the protective mesh belt, and the mesh belt fixing anchor 7 and the protective mesh belt form a connection to the roadway support, increasing the support range and maintaining the tension of the protective mesh belt.
