Abstract
Description
Technical Field
[0001] This application relates to the field of slope reinforcement technology, specifically to a slope reinforcement device for open-pit coal mines. Background Technology
[0002] Open-pit coal mines refer to coal seams deposited on the surface or in shallow layers due to geographical changes. Through direct open-pit mining, slopes are formed, altering the original equilibrium conditions and creating a risk of landslides. Therefore, slope reinforcement is necessary. Existing technologies offer various slope reinforcement methods, such as grouting, steel mesh reinforcement, and reinforcing mesh reinforcement. Reinforcing mesh reinforcement is typically a monolithic structure, making it difficult to replace damaged sections and limiting its flexibility. Therefore, this paper proposes an open-pit coal mine slope reinforcement device. Utility Model Content
[0003] The purpose of this application is to address the technical problem that reinforcement mesh is usually an integral structure, which makes it difficult to replace the damaged parts when local damage occurs, resulting in poor flexibility in use. This application provides an open-pit coal mine slope reinforcement device.
[0004] To achieve the above objectives, this application specifically adopts the following technical solution:
[0005] An open-pit coal mine slope reinforcement device includes a slope body. The slope surface of the slope body is provided with a plurality of reinforcement frames and reinforcement cylinders. Two adjacent reinforcement frames abut and overlap, and the reinforcement cylinder abuts and overlaps with all four adjacent reinforcement frames. Multiple positioning strips are provided inside each reinforcement frame. A reinforcement mesh, which abuts and overlaps with all the positioning strips, is movably installed inside each reinforcement frame. Locking elements for locking or unlocking the reinforcement mesh are provided on each reinforcement frame. A recessed hole is constructed on each reinforcement cylinder, and a threaded anchor rod is threaded into the recessed hole and extends into the slope body. A locking part for locking or unlocking the four adjacent reinforcement frames is provided on the reinforcement cylinder.
[0006] Furthermore, the locking component includes a ring plate that is slidably disposed within the reinforcing frame. The ring plate is stepped and overlaps with the reinforcing mesh. The ring plate has multiple countersunk holes, and locking bolts that are threadedly engaged with the reinforcing frame are movably inserted into the countersunk holes.
[0007] Furthermore, the locking part includes a locking plate that is movably sleeved on the reinforcing cylinder and abuts and overlaps with the four adjacent reinforcing frames. The reinforcing frame is provided with a plurality of locking holes. The locking plate is provided with a plurality of locking blocks that are inserted and engaged with the locking holes. The reinforcing cylinder is threaded with a locking nut that abuts and overlaps with the locking plate.
[0008] Furthermore, sealing plugs are tightly inserted into both the recessed hole and the countersunk hole.
[0009] Furthermore, the reinforced frame is provided with multiple drainage outlets.
[0010] Furthermore, the bottom of the slope body is provided with multiple protective frames that abut and overlap in sequence. Adjacent protective frames are connected and fixed by connecting bolts. Multiple triangular blocks that abut and overlap with the reinforcement frame are provided on the protective frame. Reinforcement anchor rods that penetrate deep into the slope body are movably inserted on the protective frame.
[0011] Furthermore, a protective net is provided on the protective frame.
[0012] Furthermore, the protective frame is equipped with reinforcing rods by mounting bolts, and the free end of the reinforcing rods abuts and overlaps with the reinforcing frame, and the two are connected and fixed by fixing bolts.
[0013] The beneficial effects of this application are as follows: This application adopts a decomposition approach, breaking down the overall structure in the prior art into multiple relatively independent individuals. When a local reinforcement mesh is damaged, it is easier to replace the damaged reinforcement mesh, improving the flexibility of use and thus making it more practical. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0025] like Figures 1-9 As shown in one embodiment of this application, an open-pit coal mine slope reinforcement device includes a slope body 1. The slope body 1 has a slope bottom, a slope surface, and a slope top distributed sequentially from bottom to top. The slope bottom and slope top are both horizontal, while the slope surface is inclined. The slope surface of the slope body 1 is provided with a plurality of reinforcement frames 2 and reinforcement cylinders 3. Two adjacent reinforcement frames 2 abut and overlap, and the reinforcement cylinders 3 abut and overlap with four adjacent reinforcement frames 2. A plurality of positioning strips 4 are provided inside the reinforcement frames 2, and the plurality of positioning strips 4 are fixed. The reinforcing frame 2 is evenly distributed and has a reinforcing mesh 5 that is movably installed inside the reinforcing frame 2 and overlaps with multiple positioning strips 4. The reinforcing frame 2 is provided with a locking element for locking or unlocking the reinforcing mesh 5. The reinforcing cylinder 3 is constructed with a recessed hole 6, which is constructed along the length of the reinforcing cylinder 3. A threaded anchor rod 7 that penetrates into the slope body 1 is threaded inside the recessed hole 6. The free end of the threaded anchor rod 7 is constructed in a conical shape. The reinforcing cylinder 3 is provided with a locking part for locking or unlocking four adjacent reinforcing frames 2.
[0026] Before reinforcement, the reinforcement mesh 5 can be pre-installed. The reinforcement mesh 5 is placed horizontally on the ground, positioned horizontally and movably within the reinforcement frame 2. The reinforcement mesh 5 overlaps with multiple positioning strips 4, and is then locked in place using locking devices. This process is repeated to install multiple reinforcement meshes 5. During reinforcement, the reinforcement cylinder 3 is installed first. It is placed on the slope, and the threaded anchor rod 7 is threaded into the recessed hole 6 and extends deep into the slope body 1. This process is repeated to install multiple reinforcement cylinders 3, ensuring that adjacent reinforcement cylinders 3 are equidistantly distributed. Then, multiple reinforcing frames 2 are laid on the slope in sequence, so that two adjacent reinforcing frames 2 abut and overlap, and the reinforcing cylinder 3 abuts and overlaps with four adjacent reinforcing frames 2. The four adjacent reinforcing frames 2 are locked by the locking part. When the local reinforcing net 5 is damaged, the damaged reinforcing net 5 is unlocked by the locking part, so that the reinforcing net 5 moves away from the reinforcing frame 2 and multiple positioning strips 4. Then, the new reinforcing net 5 is movably set in the reinforcing frame 2 and abuts and overlaps with multiple positioning strips 4. The new reinforcing net 5 is then locked by the locking part. The damaged reinforcing net 5 can be replaced, improving the flexibility of use.
[0027] In summary, this application adopts a decomposition approach, breaking down the overall structure in the prior art into multiple relatively independent components. When a local reinforcement mesh 5 is damaged, it is easier to replace the damaged reinforcement mesh 5, improving the flexibility of use and thus making it more practical.
[0028] like Figures 2-9 As shown, in some embodiments, the locking element includes a ring plate 8 slidably disposed within the reinforcing frame 2. The ring plate 8 is stepped and overlaps with the reinforcing mesh 5. The ring plate 8 has a plurality of countersunk holes 9. Locking bolts 10 that are threadedly engaged with the reinforcing frame 2 are movably inserted into the countersunk holes 9. The reinforcing frame 2 has a plurality of threaded holes. The plurality of countersunk holes 9 are respectively connected to the plurality of threaded holes. The locking bolts 10 are threadedly engaged with the threaded holes.
[0029] Referring to the above, when locking the reinforcing mesh 5, the ring plate 8 is slidably set inside the reinforcing frame 2 and abuts against and overlaps with the reinforcing mesh 5. Multiple countersunk holes 9 are connected to multiple threaded holes respectively. Then, the locking bolt 10 is movably inserted into the countersunk hole 9 and tightened. Through the threaded engagement between the locking bolt 10 and the threaded hole, the ring plate 8 and the reinforcing frame 2 are fixed, thereby locking the reinforcing mesh 5. Conversely, by loosening the locking bolt 10 until it exits the threaded hole, the ring plate 8 is slid away from the reinforcing mesh 5 and the reinforcing frame 2, and the reinforcing mesh 5 can be unlocked.
[0030] like Figures 2-5As shown, in some embodiments, the locking part includes a locking plate 11 that is movably sleeved on the reinforcing cylinder 3 and abuts and overlaps with four adjacent reinforcing frames 2. The reinforcing frame 2 is provided with a plurality of locking holes 12. The locking plate 11 is provided with a plurality of locking blocks 13 that are inserted into the locking holes 12. The locking blocks 13 are fixed on the locking plate 11. The reinforcing cylinder 3 is threadedly sleeved with a locking nut 14 that abuts and overlaps with the locking plate 11. The reinforcing cylinder 3 is provided with a threaded section, and the locking nut 14 is threadedly engaged with the threaded section.
[0031] Referring to the above, when locking the four adjacent reinforcing frames 2, the locking plate 11 is movably sleeved on the reinforcing cylinder 3 until the locking plate 11 and the four adjacent reinforcing frames 2 are all in contact and overlap. During this process, multiple locking blocks 13 are respectively inserted into the locking holes 12 on the four adjacent reinforcing frames 2. Then, the locking nut 14 is threaded onto the reinforcing cylinder 3 until the reinforcing cylinder 3 and the locking plate 11 are in contact and overlap, thus locking the four adjacent reinforcing frames 2. Conversely, the locking nut 14 is loosened away from the reinforcing cylinder 3 and the locking plate 11, so that the locking plate 11 is away from the four adjacent reinforcing frames 2. The multiple locking blocks 13 are respectively disengaged from the locking holes 12 on the four adjacent reinforcing frames 2, thus unlocking the four adjacent reinforcing frames 2.
[0032] like Figures 4-7 As shown, in some embodiments, sealing plugs 15 are tightly inserted into both the recessed hole 6 and the countersunk hole 9. The sealing plug 15 in the recessed hole 6 has a stepped structure and abuts and overlaps with the threaded anchor rod 7 and the locking nut 14. The sealing plug 15 in the countersunk hole 9 abuts and overlaps with the locking bolt 10.
[0033] Referring to the above, during reinforcement, multiple sealing plugs 15 are tightly inserted into multiple recessed holes 6 and multiple countersunk holes 9. The sealing plugs 15 can play a waterproof role, preventing rainwater from entering the recessed holes 6 and countersunk holes 9, thereby preventing the threaded anchor rods 7, locking bolts 10 and locking nuts 14 from rusting.
[0034] like Figure 7 As shown, in some embodiments, the reinforcing frame 2 is provided with a plurality of drainage outlets 16;
[0035] Referring to the above, when it rains, multiple drainage outlets 16 are used to guide the rainwater, allowing it to flow down the slope and preventing it from accumulating inside the reinforced frame 2.
[0036] like Figures 1-9As shown, in some embodiments, the bottom of the slope body 1 is provided with a plurality of protective frames 17 that abut and overlap in sequence. Adjacent protective frames 17 are connected and fixed by connecting bolts 18. The protective frame 17 has through holes. The connecting bolts 18 include a screw and a nut. The screw is movably inserted into the through hole. The nut is threaded on the screw and abuts and overlaps with the protective frame 17 to realize the connection and fixation of adjacent protective frames 17. The protective frame 17 is provided with a plurality of triangular blocks 19 that abut and overlap with the reinforcing frame 2. The triangular blocks 19 are fixed on the protective frame 17. The reinforcing anchor rods 20 that penetrate into the slope body 1 are movably inserted into the protective frame 17. The reinforcing anchor rods 20 are vertical. The protective frame 17 has vertical through holes. The reinforcing anchor rods 20 are movably inserted into the through holes.
[0037] Referring to the above, during reinforcement, multiple protective frames 17 are placed at the bottom of the slope and overlap in sequence. Adjacent protective frames 17 are connected and fixed by connecting bolts 18. Triangular blocks 19 and the reinforcement frame 2 located below overlap in contact. Then, reinforcement anchor rods 20 are movably inserted on the protective frames 17 and penetrate into the slope body 1, thereby fixing the protective frames 17. The protective frames 17 and triangular blocks 19 together form a support structure to support the reinforcement frame 2, thereby improving the reinforcement strength.
[0038] like Figure 5 As shown, in some embodiments, a protective net 21 is provided on the protective frame 17, and the protective net 21 is vertical and fixed on the protective frame 17.
[0039] Referring to the above, during reinforcement, the installation of protective netting 21 can protect against falling stones, thereby improving safety.
[0040] like Figures 5-8 As shown, in some embodiments, a reinforcing rod 23 is provided on the protective frame 17 by mounting bolts 22. The reinforcing rod 23 is horizontal. The protective frame 17 has a through hole, and the reinforcing rod 23 has a threaded hole and a through hole. The mounting bolts 22 are movably inserted into the through hole and threadedly engaged with the threaded hole to achieve the connection and fixation of the reinforcing rod 23 and the protective frame 17. The free end of the reinforcing rod 23 abuts and overlaps with the reinforcing frame 2, and the two are connected and fixed by fixing bolts 24. The reinforcing frame 2 has a threaded hole, and the fixing bolts 24 are movably inserted into the through hole and threadedly engaged with the threaded hole to achieve the connection and fixation of the reinforcing rod 23 and the reinforcing frame 2.
[0041] Referring to the above, during reinforcement, the reinforcing rod 23 is placed horizontally on the protective frame 17, so that the free end of the reinforcing rod 23 abuts and overlaps with the reinforcing frame 2. The reinforcing rod 23 is connected and fixed to the protective frame 17 by the mounting bolt 22, and the reinforcing rod 23 is connected and fixed to the reinforcing frame 2 by the fixing bolt 24. The reinforcing rod 23 provides further support to the reinforcing frame 2, thereby further improving the reinforcement strength.
