[0001] This utility model relates to the field of mining technology, specifically to an underground advanced temporary roadway support device. Background Technology

[0002] In underground mining operations, numerous tunnels need to be excavated and supported to maintain unobstructed passage and the stability of the surrounding rock. The fundamental purpose of tunnel support is to reduce displacement and deformation of the surrounding rock, thereby extending the service life of the tunnels and improving the mine's production efficiency.

[0003] However, in actual construction, due to factors such as equipment quality, technical level, and construction management, the installation of support equipment often lags behind the tunnel excavation progress. This situation results in the surrounding rock being unsupported after tunnel excavation, increasing the danger to construction workers and the difficulty of tunnel maintenance. This phenomenon of support lagging behind excavation poses a threat to tunnel excavation and the safety of personnel.

[0004] To address the aforementioned issues, this application proposes an underground advanced temporary roadway support device. Utility Model Content

[0033] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the illustrations in a simple schematic manner.

[0034] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0035] In the process of underground mining, a large number of tunnels need to be excavated. Therefore, the use of tunnel support to keep the tunnels unobstructed and the surrounding rock stable is of great significance to the construction and production of underground mines. The basic purpose of tunnel support is to mitigate and reduce the displacement and deformation of the surrounding rock, extend the service life of the tunnels, and improve the mine's production efficiency.

[0036] However, during the excavation of underground mine tunnels, due to reasons such as equipment quality, technology, and construction management, the installation of support equipment often cannot keep up with the progress of excavation. This results in the surrounding rock being unsupported after the tunnel is excavated, increasing the danger to construction workers and the difficulty of tunnel maintenance. There is a phenomenon where support lags behind excavation, threatening tunnel excavation and the safety of personnel.

[0037] Please refer to the underground advanced temporary roadway support device provided by this utility model. Figure 1 , Figure 2 It includes a support frame 1 for support, and a protective plate 2 for supporting the tunnel dome is provided on the support frame 1.

[0038] The support frame 1 includes a support member 13. There are several support members 13, and each pair of support members 13 has a threaded through hole at one end that is close to each other. An adjusting rod 12 is installed at the through hole. The adjusting rod 12 is threaded and is adapted to the threaded through hole.

[0039] The top of the support member 13 is provided with a mounting groove 14, which is adapted to the guard plate 2 and is used to support the guard plate 2.

[0040] Among them, the guard plate 2 is arc-shaped and fits the top of the tunnel, closely adhering to the tunnel dome, which can effectively disperse the pressure from the top.

[0041] The guard plate 2 includes a plate body 21. The bottom of the plate body 21 is supported by a support block 24 and a top rod 23. A support plate 25 is provided at the bottom of the top rod 23. The support plate 25 is installed on the inner side of the plate body 21 of the guard plate 2.

[0042] Please see Figures 1-7 Each pair of support members 13 has a threaded through hole at one end that is close to each other, for installing an adjusting rod 12. The distance between the support members 13 can be adjusted by rotating the adjusting rod 12 to accommodate tunnels of different widths.

[0043] When connecting, the threaded through holes opened on the support member 13 are threaded through holes with different directions of rotation. At this time, the screw can be rotated to adjust the two support members 13.

[0044] In another adjustment method, the screw holes of the two support members 13 have the same direction of rotation, and the screw has two mirror threads arranged symmetrically. In this case, the support members 13 can also be adjusted.

[0045] Understandably, the screw can be replaced with a telescopic component, such as a double-ended pneumatic rod or a double-ended hydraulic rod, to achieve the same adjustment requirement.

[0046] The adjusting rod 12 is threaded and matches the threaded through hole on the support member 13. By rotating the adjusting rod 12, the position of the support member 13 can be adjusted to ensure the stability of the support frame 1.

[0047] The top of the support member 13 is provided with a mounting groove 14, which is adapted to the guard plate 2 and used to fix the guard plate 2. The mounting groove 14 ensures a tight connection between the guard plate 2 and the support member 13, and improves the stability of the overall support structure.

[0048] The guard plate 2 includes a plate body 21, the bottom of which is supported by a support block 24 and a top rod 23. The bottom of the top rod 23 is provided with a support plate 25, which is embedded in the inner side of the plate body 21 of the guard plate 2. The combination of the top rod 23 and the support plate 25 further improves the support strength of the guard plate 2.

[0049] The support block 24 is located at the bottom of the guard plate 2 body 21 and is connected to the push rod 23 through a shaft-like part. At this time, the push rod 23 can be adjusted according to the angle of the support.

[0050] The threaded design of the adjusting rod 12 allows for flexible adjustment of the position of the support frame 1 according to the specific size and shape of the tunnel, ensuring the stability and adaptability of the support structure. The arc-shaped setting of the guard plate 2 and the combination of the support block 24 and the top rod 23 greatly improve the strength of the support structure, ensuring stable support force even under high pressure. The modularity of the support frame 1 and the guard plate 2 makes the installation and disassembly process simple and quick, reducing construction time and labor costs, and improving construction efficiency.

[0051] By using advanced temporary support, the displacement and deformation of the surrounding rock were effectively reduced, the risks to construction workers were lowered, construction safety was ensured, and the stable support structure reduced the damage to the surrounding rock of the roadway, extended the service life of the roadway, and improved the production efficiency of the mine.

[0052] In some embodiments, as Figure 1-Figure 4 As shown, a sliding groove 26 is provided on the inner side of the plate 21. The sliding groove 26 is slidably connected to the support plate 25, and both ends of the plate 21 are provided with connecting protrusions 28, which are adapted to the mounting grooves 14 on the support member 13.

[0053] With the above configuration, the slide groove 26 allows the support plate 25 to be snapped into place inside the plate 21, ensuring a tight fit between the support plate 25 and the guard plate 2, which can improve the support strength and stability of the guard plate 2.

[0054] The connecting protrusions 28 provided at both ends of the plate 21 can be adapted to the mounting grooves 14 on the support member 13, which can ensure a stable connection between the guard plate 2 and the support member 13 and prevent the guard plate 2 from shifting or falling off when subjected to force.

[0055] The bottom of the support plate 25 is slidably connected to the groove 26 on the inner side of the guard plate 2, thereby dispersing and absorbing the pressure from the surrounding rock and reducing the direct impact on the guard plate 2 and the support member 13.

[0056] The connecting protrusion 28 allows the two ends of the guard plate 2 to be precisely embedded in the mounting groove 14 of the support member 13, which not only enhances the connection stability between the guard plate 2 and the support member 13, but also simplifies the installation process and improves construction efficiency.

[0057] Please see Figures 1-7 The support plate 25 includes a body 251. Several horizontally arranged load-bearing blocks 22 are provided on the top of the body 251, and a support shaft 253 is installed on the top of the load-bearing blocks 22. The support shaft 253 is adapted to the bottom of the top rod 23 to support the top rod 23.

[0058] The top of the body 251 of the support plate 25 is provided with several load-bearing blocks 22. These load-bearing blocks 22 are evenly distributed and can effectively disperse the pressure from the top rod 23. The support shaft 253 installed on the top of the load-bearing block 22 allows the top rod 23 to be stably installed on the load-bearing block 22, ensuring a firm connection between the top rod 23 and the load-bearing block 22.

[0059] The push rod 23 is adapted to the support shaft 253 to ensure that the push rod 23 can be stably installed on the support shaft 253. In order to ensure the angle adjustment of the push rod 23, the push rod 23 then makes a circular motion on the support shaft 253 to cooperate with the bottom of the plate 21 to form a reliable connection.

[0060] The top rod 23 is pressurized by hydraulic or mechanical devices to further improve the support strength of the guard plate 2, and can effectively absorb and disperse the pressure from the surrounding rock.

[0061] The combination of multiple load-bearing blocks 22 on the support plate 25 and the support shaft 253 effectively improves the support strength and stability of the support structure. The matching design of the top rod 23 and the support shaft 253 ensures the stability of the top rod 23 under stress, preventing the top rod 23 from shifting or falling off. The uniform distribution of the load-bearing blocks 22 allows the pressure of the top rod 23 to be evenly distributed on the support plate 25, reducing local stress concentration and improving the pressure resistance of the overall support structure.

[0062] Furthermore, a reinforcement member 252 can be provided at the bottom of the support shaft 253. The reinforcement member 252 is adapted to the outer side of the support shaft 253, which further improves the stability of the support shaft 253.

[0063] In addition, to ensure the stability and adaptability of the support, a telescopic component 11 can be provided at the bottom of the support component 13. The bottom of the telescopic component 11 is adapted to the bottom of the roadway. The inner sides of multiple support components 13, together with the guard plate 2, form a protective area 15 for the protection of the dome of the roadway.

[0064] Please see Figure 4 In another embodiment, the protective plate 2 can be configured as multiple, specifically:

[0065] There are several bodies 251, and every two bodies 251 are connected by connectors 27.

[0066] In this connection method, the main body 251 can be adapted to the irregular height of the dome. With the use of the top rod 23 and the support plate 25, it can achieve the supporting effect, meet the needs of use, and fit the dome better, thereby supporting the dome.

[0067] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
