Description

Technical Field

[0001] The utility model relates to the technical field of ore mining, in particular to a stope support device. Background Art

[0002] During the mining process of ore, the tunnel needs to be supported, and a support device is needed to increase the safety of the mine tunnel and avoid rockfall. For example, patent application number CN202320242249.8 discloses a mine tunnel support structure. The patent drives the threaded rod to rotate by a knob, and the threaded rod is engaged with the threaded sleeve to vertically move the threaded sleeve, the movable plate and the limit rod, so that the anchor rod is inserted into the tunnel ground to fix the support device, so that the movable plate contacts the ground of the tunnel, and the support mechanism is raised by continuing to rotate the knob and the threaded rod, which facilitates the support and protection of tunnels at different heights. The top surface of the first support top plate contacts the top surface of the tunnel, and the second support top plate and the first support top plate provide double-layer protection to improve safety.

[0003] However, the existing tunnel support is only suitable for temporary construction and not for fixed use. The main reason is that the bottom has universal wheels, which are very easy to be damaged. At the same time, once the threaded rod of the adjustment mechanism is deformed after being subjected to force, the threaded sleeve cannot move on the threaded rod and cannot be repaired.

[0015] The support plates and top plates provided in this application can support the tunnel. For the sake of stability, embedded plates are connected between the two support plates. The embedded plates can be embedded in the concrete, which can ensure that the concrete is not easily crushed by vehicles. At the same time, it can increase the stability of the support plates. In addition, a connecting rod is provided between two adjacent embedded plates to further increase the stability of the embedded plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic diagram of a stope support device of the present utility model.

[0017] Figure 2 It is a schematic diagram of a baffle on the embedded plate of the utility model.

[0018] Among them: top plate 10, support plate 20, positioning sleeve 21, baffle 30, positioning plate 40, limiting groove 50, embedded plate 60, plug plate 61, connecting rod 70, positioning groove 71, baffle 80, and baffle groove 81. DETAILED DESCRIPTION

[0019] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-2 In this embodiment 1, a stope support device includes

[0021] Several top plates 10, each with a support plate 20 on both sides;

[0022] A plurality of baffles 30, both ends of which are connected to two adjacent top plates 10 and support plates 20;

[0023] If the embedded plates 60 are included, they are respectively located below the top plate 10 and between the two support plates 20 and fixedly connected to the support plates 20;

[0024] A plurality of connecting rods 70 are located between two adjacent embedded plates 60;

[0025] The embedded plate 60 has a positioning groove 71 at a position corresponding to the connecting rod 70 , and the connecting rod 70 extends into the positioning groove 71 .

[0026] This embodiment is implemented as follows:

[0027] When the present application is in use, the top plate 10 on the support plate 20 can support the inner wall of the tunnel, and the retaining net 30 can prevent large pieces of falling rocks. In the present application, the embedded plate 60 is embedded in the bottom concrete of the tunnel and connected to the two support plates 20. This not only increases the stability of the support plate 20, but also prevents the concrete from being crushed by the mine car, thereby increasing the stability of the concrete floor.

[0028] The advantage of the present application over the prior art is that it can increase the stability of the support plate and is suitable for tunnel support.

[0029] See also Figure 1 , both sides of the support plate 20 are provided with positioning sleeves 21.

[0030] The support plate 20 is conveniently fixed by passing the positioning pins through the positioning sleeves 21 and connecting them to the inner wall of the tunnel.

[0031] See also Figure 1 、 2 A plurality of positioning plates 40 are fixedly connected to the positions of the support plate 20 corresponding to the embedded plates 60 , and a limiting groove 50 is formed between two adjacent positioning plates 40 . The positions of the embedded plates 60 corresponding to the limiting grooves 50 have inserting plates 61 extending into the limiting grooves 50 .

[0032] By extending the inserting plate 61 on the embedded plate 60 into the limiting groove 50 formed by the adjacent positioning plate 40, the horizontal position of the embedded plate 60 can be limited, and the stability is enhanced.

[0033] See also Figure 2 The upper surface of the embedded plate 60 has a baffle 80 , and the position of the positioning plate 40 corresponding to the baffle 80 has a baffle groove 81 , and the baffle 80 extends into the baffle groove 81 .

[0034] By fixing the baffle 80 on the embedded plate 60 and extending the baffle 80 into the retaining groove 81 of the positioning plate 40, the vertical position of the baffle 80 can be limited, thereby limiting the vertical position of the embedded plate 60, thereby further improving stability.

[0035] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, and these all fall within the scope of protection of the present invention.
