Description

Technical Field

[0001] This utility model relates to the technical field of side-cutting and top-relief structures for roadways under strong dynamic pressure, and particularly to a side-cutting and top-relief structure for roadways under strong dynamic pressure. Background Technology

[0002] The high-pressure roadway side-cutting and roof-relief structure is an advanced roadway support and surrounding rock control technology for areas of abnormal stress concentration in mining. Its core idea is "guidance rather than confrontation", that is, by actively and deliberately destroying the key structure of the overlying strata, the concentrated pressure acting on the roadway is transferred to the deep parts on both sides of the roadway, thereby creating a stable "low-pressure protection zone" for the roadway.

[0003] Existing dynamic pressure roadway side-cutting and top-relief structures are composed of various components, including perforated plates to prevent coal collapse. Adjacent perforated plates are connected using a combination of screws, nuts, and pressure plates. However, because the screws cannot fully fit into the perforated grooves of the perforated plates, the connection using screws, nuts, and pressure plates cannot guarantee a tight connection between adjacent perforated plates. Therefore, the existing perforated plate connectors in dynamic pressure roadway side-cutting and top-relief structures are inconvenient to use. To address this, we provide a new dynamic pressure roadway side-cutting and top-relief structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the hollow plate of the side-cutting and top-relief structure for high dynamic pressure roadways cannot be tightly fixed using connectors, and to provide a side-cutting and top-relief structure for high dynamic pressure roadways.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-pressure roadway side-cutting and top-relief structure, comprising: a protective mechanism, the protective mechanism comprising a perforated plate one, a perforated plate two on one side of the perforated plate one, a fastening mechanism on one side of the perforated plate two, the fastening mechanism comprising a horizontal block one, a horizontal block two at one end of the horizontal block one, threaded rods sleeved inside both the horizontal block one and the horizontal block two, a movable block threadedly connected to the outer surface of the threaded rods, a connecting rod one at the top of the movable block, a connecting rod two at the bottom of the movable block, and an anti-detachment block fixedly connected to one end of both the connecting rod one and the connecting rod two.

[0006] In a preferred embodiment, the threaded rod is rotatably connected to the inner walls of both horizontal blocks one and two, and the movable block is sleeved inside horizontal blocks one and two.

[0007] In a preferred embodiment, the movable block is slidably connected to the inner walls of both horizontal block one and horizontal block two, the connecting rod one is fixedly connected to the movable block, and the connecting rod two is fixedly connected to the movable block.

[0008] In a preferred embodiment, a slider is fitted inside the second horizontal block, the slider is slidably connected to the inner wall of the second horizontal block, and the slider is fixedly connected to the first horizontal block.

[0009] In a preferred embodiment, a support block is provided on one side of the first horizontal block, the support block is fixedly connected to the first horizontal block, and a limiting piece is provided at one end of the threaded rod.

[0010] In a preferred embodiment, the limiting plate is fixedly connected to the threaded rod, and the limiting plate is rotatably connected to the inner walls of both horizontal block one and horizontal block two.

[0011] In a preferred embodiment, one end of the threaded rod is provided with a rotating block, which is fixedly connected to the threaded rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention, through the setting of a fastening mechanism, allows adjacent perforated plates one and two to be connected in a butt joint manner, thereby forming a more stable whole that can more effectively block large pieces of coal. A threaded rod is provided, and when the threaded rod rotates, it can drive the moving block in a threaded manner, allowing the moving block to move back and forth. This enables the connecting rod one and connecting rod two, which are fixedly connected to the moving block, to drive the anti-detachment block to tightly and securely fit onto the outer surface of perforated plates one and two. The setting of a support block allows the horizontal block one and the anti-detachment block to be quickly positioned appropriately. Furthermore, when the position of the anti-detachment block is adjusted using the threaded rod inside the horizontal block one, the anti-detachment block can be precisely fitted onto the outer surface of perforated plate two.

[0017] 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.

[0018] Example 1 like Figures 1-3 As shown, this utility model provides a technical solution: a side-cutting and top-relief structure for a high-pressure roadway, comprising: a protective mechanism 1, the protective mechanism 1 including a perforated plate 11, a perforated plate 12 on one side of the perforated plate 11, a fastening mechanism 2 on one side of the perforated plate 12, the fastening mechanism 2 including a horizontal block 21, a horizontal block 22 at one end of the horizontal block 21, threaded rods 23 are sleeved inside both the horizontal block 21 and the horizontal block 22, a moving block 24 is threadedly connected to the outer surface of the threaded rod 23, a connecting rod 25 is provided at the top of the moving block 24, a connecting rod 26 is provided at the bottom of the moving block 24, and an anti-detachment block 27 is fixedly connected to one end of both the connecting rod 25 and the connecting rod 26.

[0019] In this embodiment, by providing an anti-detachment block 27, and ensuring that the inner dimensions of the anti-detachment block 27 are appropriately matched to the thicknesses of the first perforated plate 11 and the second perforated plate 12, the anti-detachment block 27 will prevent the first perforated plate 11 and the second perforated plate 12 from wobbling within the anti-detachment block 27 when it is fitted onto their outer surfaces. Simultaneously, horizontal blocks 1 21 and 2 22 are provided, and these blocks can be used alternately via a slider 28. Therefore, the positions of the horizontal blocks 1 21 and 2 22 can be adjusted according to actual usage. The situation is finely adjusted so that any errors in the connection between the first hollow plate 11 and the second hollow plate 12 can be compensated in time, so that the anti-detachment block 27 can be fitted onto the outer surface of the first hollow plate 11 and the second hollow plate 12. A threaded rod 23 is provided, and when the threaded rod 23 rotates, it can drive the moving block 24 by thread, so that the moving block 24 can move back and forth, so that the connecting rod 25 and the connecting rod 26, which are fixedly connected to the moving block 24, can drive the anti-detachment block 27 to be tightly and securely fitted onto the outer surface of the first hollow plate 11 and the second hollow plate 12.

[0020] Example 2 like Figures 1-3As shown, the threaded rod 23 is rotatably connected to the inner walls of both horizontal block 21 and horizontal block 22. The movable block 24 is sleeved inside both horizontal block 21 and horizontal block 22, and is slidably connected to the inner walls of both horizontal block 21 and horizontal block 22. The connecting rod 25 is fixedly connected to the movable block 24, and the connecting rod 26 is fixedly connected to the movable block 24. A slider 28 is sleeved inside horizontal block 22, and is slidably connected to the inner wall of horizontal block 22. The slider 28 is fixedly connected to horizontal block 21. A support block 29 is provided on one side of horizontal block 21, and is fixedly connected to horizontal block 21. A limiting piece 201 is provided at one end of the threaded rod 23, and is fixedly connected to the threaded rod 23. The limiting piece 201 is rotatably connected to the inner walls of both horizontal block 21 and horizontal block 22. A rotating block 202 is provided at one end of the threaded rod 23, and is fixedly connected to the threaded rod 23.

[0021] In this embodiment, when the support block 29 is provided and its size is matched with that of the anti-detachment block 27, and the support block 29 is fitted onto the outer surface of the perforated plate 11, the distance between the horizontal block 21 and the perforated plate 11 is consistent. Therefore, when it is necessary to use the horizontal block 21 and the anti-detachment block 27 that works with the horizontal block 21, the support block 29 allows the horizontal block 21 and the anti-detachment block 27 to be quickly positioned in a suitable state. Thus, when the position of the anti-detachment block 27 is adjusted using the threaded rod 23 inside the horizontal block 21, the anti-detachment block 27 can be precisely fitted onto the outer surface of the perforated plate 12.

[0022] Working principle: like Figures 1-3As shown, when using this utility model, if it is necessary to connect the upright perforated plate 11 and perforated plate 22, the support block 29, which is fixedly connected to the horizontal block 21, can be first attached to the perforated plate 22. At this time, the horizontal block 21 and the anti-detachment block 27 can be in a suitable position, and the anti-detachment block 27 can be placed in a perforated hole opened on the perforated plate 22. Then, a tool that matches the rotating block 202 is used to drive the threaded rod 23 to rotate. With the cooperation of the limiting piece 201, the threaded rod 23 can drive the moving block 24 to move, so that the moving block 24 can drive the connecting rod 125 and the connecting rod 26 fixedly connected to it to move. Under the drive of the connecting rod 125 and the connecting rod 26, the anti-detachment block 27 can be tightly sleeved on the outer surface of the perforated plate 22. At this time, the horizontal block 11 and the anti-detachment block 27 can be tightly sleeved on the outer surface of the perforated plate 22. After stabilizing the first plate, the anti-detachment block 27, which cooperates with the second horizontal block 22, is fitted onto the outer surface of the first perforated plate 11. The position of the anti-detachment block 27, which cooperates with the second horizontal block 22, is adjusted in the same way. If the position of the anti-detachment block 27 is offset, the position of the second horizontal block 22 can be slid so that the second horizontal block 22 can be in a suitable position under the guidance of the slider 28, until the anti-detachment block 27 can be fitted onto the outer surface of the first perforated plate 11. All anti-detachment blocks 27 can be tightly fitted onto the outer surface of the first perforated plate 11 or the second perforated plate 12 in subsequent adjustments. Thus, the first perforated plate 11 and the second perforated plate 12 can be further tightly connected, so that the first perforated plate 11 and the second perforated plate 12 can be further connected and fixed after being erected during construction, thereby ensuring the stability of the two when used together.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
