Description

Technical Field

[0001] This utility model relates to the field of mine roadway support technology, specifically a temporary support device for mine roadways. Background Technology

[0002] When open-pit mining reaches a certain depth, underground mining methods are required. This necessitates the creation of various passages between the surface and the ore body, forming roadways. When various operations are carried out through these roadways, temporary support equipment is needed to support the interior of the roadways and ensure safety during mining operations.

[0003] For example, CN219472129U discloses a roadway support device, belonging to the field of roadway support technology. It includes two columns and a top beam located at the top of the columns. A base plate is installed at the bottom of the columns, and the top beam is arched. Through holes are provided at both ends of the top beam and both ends of the columns. The top beam and columns are detachably connected. This utility model is easy to install. During installation, one side of the columns is first positioned and fixed with the base plate, then the other side of the columns is installed. After installation, one end of the top beam is first connected and fixed to the top of the column, and then the other end is fixed. Installation is simple and convenient, with high stability and support effect. The arc of the top beam can be adjusted by the threaded tightening component, which facilitates the installation of the top beam and improves installation convenience.

[0004] For example, CN114382504A discloses a tunnel support structure comprising: a first spray layer applied to the surface of the tunnel, the first spray layer having a porous media structure; one end of an anchoring structure penetrating the first spray layer and placed in the tunnel, the other end of the anchoring structure placed on the side of the first spray layer away from the tunnel, and the anchoring structure having a pre-tightening force. The tunnel support structure provided by this utility model, by setting a first spray layer with a porous media structure on the surface of the tunnel, has a good energy absorption effect and can also scatter and attenuate shock waves reaching the surrounding rock, reducing damage to the surrounding rock of the tunnel; setting an anchoring structure on the first spray layer, so that the anchoring structure and the first spray layer have a pre-tightening force, strengthen the first spray layer, and at the same time, the first spray layer can effectively homogenize the stress distribution of the impact force on the anchoring structure, protect the anchoring structure, and reduce the deformation and damage of the anchoring structure;

[0005] However, the support equipment mentioned in the above application still has some shortcomings in use. For example, as a temporary support, it is not convenient to disassemble and assemble the support equipment, which delays the work time and causes inconvenience to the staff. Moreover, during the support process, it is not convenient to reinforce and support the roadway in all directions at the same time, which reduces safety and also reduces the effectiveness of the support equipment.

[0006] Therefore, we propose a temporary support device for mine roadways to solve the problems mentioned above. Utility Model Content

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Example 1:

[0044] This embodiment discloses the method of supporting and reinforcing the tunnel body 1 using a first support plate 2 and a second support plate 3, and ensuring a firm connection between the first support plate 2 and the second support plate 3, specifically as follows: Figures 1-2 , Figure 4 , Figure 6 , Figures 9-11 As shown,

[0045] The inner side of the tunnel body 1 is provided with a first support plate 2 and a second support plate 3. A horizontal plate 4 is installed on the inner wall of the second support plate 3, and a hydraulic rod 5 is fixed to the upper surface of the horizontal plate 4 by screws. The output end of the hydraulic rod 5 is connected to an installation plate 6.

[0046] The first support plate 2 and the second support plate 3 are both fixed to the inner wall of the tunnel body 1 by bolts. The first support plate 2 and the second support plate 3 are both arc-shaped. There are two second support plates 3. The lower surface of the first support plate 2 is provided with a side baffle 9. The inner wall of the side baffle 9 is connected to a fixing airbag 10. The fixing airbag 10 is connected to the fixing cavity 12 through a connecting pipe 11. The fixing cavity 12 is opened inside the first support plate 2. The inner side of the fixing cavity 12 is provided with a movable block 13. The end of the movable block 13 is connected to the positioning plate 14. The interior of the second support plate 3 is provided with a positioning groove 15. The positioning plate 14 and the movable block 13 are an integral structure. The movable block 13 and the inner wall of the fixing cavity 12 are slidably connected. The size of the positioning plate 14 matches the size of the positioning groove 15. The positioning groove 15 is arc-shaped.

[0047] The first support plate 2 and the second support plate 3 are installed to the tunnel body 1 with bolts. The first support plate 2 and the second support plate 3 support the tunnel body 1. Both the first support plate 2 and the second support plate 3 are arc-shaped, thus ensuring the normal operation of the support work. The hydraulic rod 5 on the upper surface of the horizontal plate 4 is activated. The hydraulic rod 5 pushes the mounting plate 6 to rise. The mounting plate 6 will drive the top plate 8 to rise together. A side baffle 9 is provided on the lower surface of the first support plate 2. The inner wall of the side baffle 9 is connected to the fixing airbag 10. So when the top plate 8 rises, it will squeeze the fixing airbag 10. This will cause the gas inside the fixing airbag 10 to enter the fixing cavity 12 through the connecting pipe 11, increasing the amount of gas inside the fixing cavity 12. This will push the movable block 13 to move. The movable block 13 will drive the positioning plate 14 to move together, so that the positioning plate 14 slides and engages in the positioning groove 15. This can make the connection between the first support plate 2 and the second support plate 3 more secure.

[0048] Example 2:

[0049] This embodiment discloses a limiting structure, in which the tunnel body 1 is supported and reinforced by the first support plate 2 and the second support plate 3, and the second vertical plate 17 can support the second support plate 3, as detailed below. Figure 8 and Figure 12 As shown:

[0050] The mounting plate 6 has a limiting structure on its side, and the limiting structure includes a fixing plate 7. The upper surface of the mounting plate 6 is connected to a top plate 8. The second support plate 3 and the horizontal plate 4 are fixed together by bolts. The upper surface of the fixing plate 7 is equipped with a first vertical plate 16, and a second vertical plate 17 is provided above the first vertical plate 16. The top of the second vertical plate 17 is connected to the second support plate 3. The first vertical plate 16 and the second vertical plate 17 are slidably connected.

[0051] When the mounting plate 6 rises, it also drives the fixing plate 7 to rise. The rise of the fixing plate 7 drives the first vertical plate 16 to rise. A second vertical plate 17 is provided above the first vertical plate 16, and the top of the second vertical plate 17 is fixed to the second support plate 3. The first vertical plate 16 and the second vertical plate 17 are slidably connected. Therefore, when the fixing plate 7 drives the first vertical plate 16 to rise, the first vertical plate 16 will slide along the second vertical plate 17. This can always support the second support plate 3. Moreover, the maximum distance the first vertical plate 16 rises is equal to the maximum distance the positioning plate 14 slides. Thus, when the positioning plate 14 and the positioning groove 15 are engaged, the first vertical plate 16 can rise stably.

[0052] Example 3:

[0053] This embodiment discloses a support structure that can simultaneously reinforce the tunnel body 1 in all directions, improving the safety of the tunnel body 1 during use. Specifically, as follows... Figure 3 , Figure 5 , Figure 7 and Figure 13 As shown:

[0054] The bottom of the fixed plate 7 is equipped with a support structure that can provide lateral support for the second support plate 3, and the support structure includes a partition plate 18.

[0055] The inner wall of the tunnel body 1 is fitted with a reinforcing plate 31 by bolts, and reinforcing rods 32 are provided on both the upper and lower sides of the reinforcing plate 31. A connecting plate 33 is installed at the top of the upper reinforcing rod 32.

[0056] A first rack 19 is provided on the inner wall of the partition 18, a rotating shaft 20 is provided above the horizontal plate 4, and a first gear 21 is installed on the outer wall of the rotating shaft 20. The first gear 21 and the second gear 22 are meshed and connected, and a third gear 23 is provided below the second gear 22. The shaft inside the second gear 22 and the shaft inside the third gear 23 are connected by a transmission belt.

[0057] The third gear 23 is meshed with the second rack 24, and the second rack 24 is mounted on the upper surface of the push plate 25. The lower surface of the push plate 25 is provided with a locking block 26, and the locking block 26 forms a sliding structure with the horizontal plate 4 through the fixing groove 27. The fixing groove 27 is opened on the inner wall of the horizontal plate 4, and there is always a gap between the partition plate 18 and the second rack 24.

[0058] A spring 28 is installed between the inner wall of the fixing groove 27 and the locking block 26. The push plate 25 is L-shaped, and a support rod 29 is installed on the outer surface of the push plate 25. A roller 30 is installed at the end of the support rod 29 away from the push plate 25.

[0059] The reinforcing rod 32 and the reinforcing plate 31 are fixed together by bolts, and the reinforcing rod 32 and the connecting plate 33 at the upper position are an integral structure, and the connecting plate 33 and the horizontal plate 4 are fixed together by bolts;

[0060] When the fixed plate 7 rises, it will drive the partition plate 18 to rise, which in turn will drive the first rack 19 to rise. The first rack 19 will drive the first gear 21 to rotate counterclockwise, and the first gear 21 will drive the rotating shaft 20 to rotate counterclockwise. Because the first gear 21 and the second gear 22 are meshed, when the first gear 21 rotates counterclockwise, it will drive the second gear 22 to rotate clockwise. This will cause the shaft inside the second gear 22 to drive the third gear 23 to rotate clockwise via the transmission belt. The third gear 23 is meshed with the second rack 24 on the upper surface of the push plate 25, thus causing the second rack 24 and the push plate 25 to move towards the second... The inner wall of the support plate 3 is close to the inner wall. When the push plate 25 moves, it will drive the locking block 26 to slide along the fixed groove 27 and squeeze the spring spring 28. Under the action of the locking block 26, the push plate 25 will move more smoothly. The outer surface of the push plate 25 is rotatably connected to one end of the support rod 29, and the other end of the support rod 29 is rotatably connected to the roller 30. So when the push plate 25 contacts the second support plate 3, the push plate 25 continues to move and will cause the roller 30 to roll against the inner wall of the second support plate 3, changing the inclination of the support rod 29. In this way, the second support plate 3 can be supported again by the support rod 29.

[0061] The inner wall of the tunnel body 1 is also equipped with a reinforcing plate 31, and reinforcing rods 32 are provided on both the upper and lower sides of the reinforcing plate 31. The upper reinforcing rod 32 is fixed to the horizontal plate 4 through the connecting plate 33. Therefore, the horizontal plate 4 can be supported by the reinforcing rod 32. Thus, by working together with the support rod 29, the second vertical plate 17 and the reinforcing rod 32, the tunnel body 1 can be simultaneously supported and reinforced, making the equipment more stable during use and easier to disassemble and assemble. Under the action of the fixing plate 7, the first gear 21, the second gear 22 and the third gear 23 can be protected, effectively reducing the impact of dust in the tunnel on the first gear 21, the second gear 22 and the third gear 23, thereby completing a series of tasks.

[0062] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
