The utility model is popularized and used at various plate hanging locations in the whole mine, and the use effect is good.

[0011] 2. In Embodiment 1 of the present utility model, the size of the plate fixing device can be changed according to the sizes of different plates, which improves the applicability of the plate fixing device and facilitates processing and manufacturing. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 is the front view of the overall structure of Embodiment 1 of the present utility model.

[0013] Figure 2 is the front view of the overall structure of Embodiment 2 of the present utility model.

[0014] The reference numerals in the attached drawings of the specification include: bottom frame 1, first fixing ear 2, first retaining rod 3, side frame 4, second fixing ear 5, second retaining rod 6, limit nut 7, baffle 8. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present utility model will be further introduced below in conjunction with the attached drawings and specific embodiments.

[0016] Embodiment 1:

[0017] A plate fixing device, as Figure 1 shown, includes a bottom frame 1 arranged in the horizontal direction. The length of the bottom frame 1 is 606 mm. A side frame 4 arranged in the vertical direction is welded to each of the left and right ends of the bottom frame 1. The height of the side frame 4 is 406 mm. The cross-sections of the bottom frame 1 and the side frame 4 are both L-shaped. The bottom frame 1 and the side frame 4 are both ∠30×30 mm angle steels; an inclined first retaining rod 3 is welded between the front side of the lower part of each side frame 4 and the bottom frame 1; a horizontal second retaining rod 6 is welded between the front sides of the upper ends of the two side frames 4; the first retaining rod 3 and the second retaining rod 6 are both ∅8 mm round steel. A first fixing ear 2 is arranged on the bottom frame 1. The first fixing ear 2 is a square iron block with a side length of 20 mm. A first through hole with a diameter of ∅8 mm is arranged on the first fixing ear 2; a second fixing ear 5 is arranged on the side frame 4. A second through hole with a diameter of ∅8 mm is arranged on the second fixing ear 5. The structure of the second fixing ear 5 is the same as that of the first fixing ear 2.

[0018] Fabricate the present utility model by welding in advance according to the size of the plate, then carry it into the underground roadway, and fix the present utility model on the side wall of the roadway by using expansion screws and the cooperation of the first through hole and the second through hole. Then place the plate between the bottom frame 1 and the side frame 4 from top to bottom. The rear sides of the bottom frame 1 and the side frame 4 prevent the plate from tilting backward, and the first retaining rod 3 and the second retaining rod 6 prevent the plate from tilting forward. When the plate needs to be replaced, directly take out the plate and put in a new plate.

[0019] Embodiment 2:

[0020] The difference between Embodiment 2 and Embodiment 1 is that:

[0021] As Figure 2 shown, the lower end of the right side frame 4 is slidably connected to the bottom frame 1 and the upper end is higher than the height of the second stop lever 6. A third through hole allowing the second stop lever 6 to pass through is provided in the upper part of the right side frame 4, and the lower part of the right side frame 4 is in the shape of a strip plate. The right end of the second stop lever 6 is a threaded rod, and a limit nut 7 is threadedly connected to the right end of the threaded rod. A baffle 8 arranged vertically is fixed to the front side of the middle parts of the left and right side baffles 8.

[0022] Since the sizes of different nameplates are different, in order to facilitate matching of nameplates of different sizes, in this embodiment, by sliding the right side baffle 8 and limiting with the limit nut 7, it can be matched with nameplates of different sizes, and has strong applicability.

[0023] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
