Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to a mobile support structure for mine support. Background Technology

[0002] Support structures are a type of support structure. In the process of mining, the support work of roadways is crucial, as it directly relates to the safety of mine workers and the smooth progress of mining operations. Support structures include mobile support structures, which can be moved by wheels.

[0003] The above-mentioned and existing technologies have the following drawbacks: Traditional mine support structures are mostly fixed, with poor flexibility, making it difficult to adapt to roadways of different shapes and sizes, resulting in unsatisfactory support effects and failing to provide reliable safety guarantees for mine mining.

[0004] Therefore, a mobile support structure for mine support is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of traditional mine support structures, which are mostly fixed, have poor flexibility, are difficult to adapt to roadways of different shapes and sizes, resulting in unsatisfactory support effects and failing to provide reliable safety guarantees for mine mining. Therefore, a mobile support structure for mine support is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mobile support structure for mine support, comprising a base plate, four second hydraulic rods fixedly installed on the surface of the base plate, a support plate fixedly installed at the output end of the four second hydraulic rods, four wheels fixedly installed on the lower surface of the base plate, two mounting plates slidably connected inside the support plate, a push plate fixedly installed at the far end of each of the two mounting plates, and four first hydraulic rods fixedly installed on the surface of the support plate, the output end of the first hydraulic rods being fixedly connected to the push plate.

[0007] The aforementioned components achieve the following effects: they can be adjusted according to the height of the mine roadway, allowing the support structure to adapt to roadways of different shapes and sizes, thereby improving the support effect of the support structure and effectively ensuring the safety of mine mining.

[0008] Preferably, two fixing plates are fixedly installed on the upper surface of the base plate, and two threaded rods are internally threaded on the fixing plates. The four threaded rods are grouped in pairs, and auxiliary plates are rotatably connected to the surfaces of the two groups of threaded rods. Rotating plates are fixedly installed on the surfaces of the threaded rods.

[0009] The effect achieved by the above components is as follows: rotating the rotating plate drives the threaded rod to move, and the threaded rod moves closer to the fixed plate. As the threaded rod moves, it drives the auxiliary plate to move. After the auxiliary plate moves a certain distance, the surface of the auxiliary plate squeezes the tunnel, thus achieving the effect of supporting the tunnel.

[0010] Preferably, four protective frames are fixedly installed on the surface of the base plate, and the cross-section of the protective frames is "L" shaped.

[0011] The effect achieved by the above components is that the protective frame can protect the threaded rod.

[0012] Preferably, a limiting pad is fixedly installed on the upper surface of the support plate, and the surface of the limiting pad is provided with anti-slip protrusions.

[0013] The effect achieved by the above components is that the limiting pad can assist the support plate in supporting the mine roadway.

[0014] Preferably, four fixing rods are fixedly inserted inside the base plate, and a connecting plate is slidably sleeved on the arc surface of the fixing rod. A fixing frame is fixedly installed on the surface of the connecting plate, and a cleaning brush is fixedly installed on the inner wall of the fixing frame. The surface of the cleaning brush is slidably connected to the wheel, and a bolt is threaded inside the connecting plate. The surface of the bolt abuts against the fixing rod.

[0015] The effect achieved by the above components is as follows: the connecting plate is placed on the fixing rod, and then the bolt is rotated. The bolt moves towards the fixing rod by means of the thread. After the bolt moves a certain distance, the surface of the bolt presses against the fixing rod. At this time, the fixing rod and the connecting plate are fixed together. At this time, the cleaning brush is fixed on the fixing rod. When the support structure is moved, the cleaning brush can remove the debris stuck on the wheels, so that the debris will not block the wheels and facilitate the movement of the support structure.

[0016] Preferably, four positioning plates are fixedly installed on the surface of the base plate, and the surfaces of the positioning plates are slidably connected to the connecting plate.

[0017] The effect achieved by the above components is that the positioning plate can assist the connecting plate in sliding, so that the connecting plate cannot rotate during the sliding process, making it convenient for workers to fix the connecting plate on the fixing rod.

[0018] Preferably, each of the four fixing frames has two threaded pins inside, and the pins slide through the cleaning brush.

[0019] The effect achieved by the above components is that the pin can fix the cleaning brush to the fixed frame, thereby improving the stability between the cleaning brush and the fixed frame.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, by setting components such as the first hydraulic rod and the second hydraulic rod, the height of the mine roadway can be adjusted according to the height of the roadway, so that the support structure can adapt to roadways of different shapes and sizes, thereby improving the support effect of the support structure and effectively ensuring the safety of mine mining.

[0022] 2. In this utility model, by setting components such as cleaning brushes and fixing frames, the cleaning brushes can remove debris adhering to the wheels when the support structure is moved, so that the debris will not clog the wheels and the support structure can be moved easily.

Detailed Implementation

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figure 1-4As shown, this utility model provides a mobile support structure for mine support, including a base plate 4. Four second hydraulic rods 15 are fixedly installed on the surface of the base plate 4. Support plates 1 are fixedly installed at the output ends of the four second hydraulic rods 15. Four wheels 5 are fixedly installed on the lower surface of the base plate 4. Two mounting plates 20 are slidably connected inside the support plate 1. Push plates 13 are fixedly installed at the ends of the two mounting plates 20 that are far apart from each other. Four first hydraulic rods 14 are fixedly installed on the surface of the support plate 1. The output ends of the first hydraulic rods 14 are fixedly connected to the push plates 13. Two fixing plates 3 are fixedly installed on the upper surface of the base plate 4. Two threaded rods 17 are threadedly connected inside the fixing plates 3. The four threaded rods 17 are connected in pairs. One set of two sets of threaded rods 17 are rotatably connected to auxiliary plates 16. A rotating plate 18 is fixedly installed on the surface of each threaded rod 17. Rotating the rotating plate 18 causes the threaded rod 17 to move closer to the fixed plate 3. This movement of the threaded rod 17 also causes the auxiliary plate 16 to move. After moving a certain distance, the surface of the auxiliary plate 16 presses against the roadway, achieving the effect of supporting the roadway. Four protective frames 19 are fixedly installed on the surface of the bottom plate 4. The protective frames 19 have an "L"-shaped cross-section and can protect the threaded rods 17. Limiting pads 2 are fixedly installed on the upper surface of the support plate 1. The surface of the limiting pads 2 has anti-slip protrusions. The positioning pad 2 assists the support plate 1 in supporting the mine roadway. Four fixing rods 11 are fixedly inserted inside the base plate 4. A connecting plate 9 slides on the arc surface of each fixing rod 11. A fixing frame 6 is fixedly installed on the surface of the connecting plate 9. A cleaning brush 7 is fixedly installed on the inner wall of the fixing frame 6. The surface of the cleaning brush 7 is slidably connected to the wheel 5. A bolt 10 is threaded inside the connecting plate 9. The surface of the bolt 10 abuts against the fixing rod 11. When the connecting plate 9 is fitted onto the fixing rod 11, and then the bolt 10 is rotated, the bolt 10 moves closer to the fixing rod 11 via the thread. After the bolt 10 moves a certain distance, the surface of the bolt 10 presses against the fixing rod 11, thus fixing the fixing rod 11 and the connecting plate 9. The cleaning brush 7 is fixed on the fixing rod 11. When the support structure is moved, the cleaning brush 7 can remove the debris stuck on the wheel 5, so that the debris will not block the wheel 5, which facilitates the movement of the support structure. Four positioning plates 12 are fixedly installed on the surface of the base plate 4. The surface of the positioning plate 12 is slidably connected to the connecting plate 9. The positioning plate 12 can assist the connecting plate 9 to slide, so that the connecting plate 9 cannot rotate during the sliding process, which makes it convenient for the staff to fix the connecting plate 9 on the fixing rod 11. The interior of each of the four fixing frames 6 is threaded with two pins 8. The pins 8 slide through the cleaning brush 7 and can fix the cleaning brush 7 on the fixing frame 6, which improves the stability between the cleaning brush 7 and the fixing frame 6.

[0031] The overall working principle is as follows: When a support structure is required, the wheel 5 is used to place the support structure in the required position. Then, the second hydraulic rod 15 is activated. The output end of the second hydraulic rod 15 drives the support plate 1 to move upward. As the support plate 1 moves, the limiting pad 2 moves. After the limiting pad 2 moves a certain distance, the surface of the limiting pad 2 presses against the top of the roadway. Then, the first hydraulic rod 14 is activated. The output end of the first hydraulic rod 14 drives the push plate 13 to move. The push plate 13 moves closer to the side wall of the roadway. After the push plate 13 moves a certain distance, the surface of the push plate 13 presses against the side wall of the roadway. Next, the rotating plate 18 is rotated. As the rotating plate 18 rotates, the threaded rod 17 moves. The threaded rod 17 moves closer to the fixed plate 3. As the threaded rod 17 moves, the auxiliary plate 16 moves. After the auxiliary plate 16 moves a certain distance, the surface of the auxiliary plate 16 presses against the roadway. At this time, the roadway is supported by the support structure.

[0032] 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.
