A vertical plate assembly 7 is installed on the side of the traction housing 1. A first vertical plate 3 is installed on the upper part of the side of the housing near the left side, and a second vertical plate 11 is installed on the upper part of the side of the housing near the right side. A first front guard plate 2 is installed between the first vertical plate 3 and the vertical plate assembly 7, and a second front guard plate 10 is installed between the vertical plate assembly 7 and the second vertical plate 11. A first lower guard plate 5, a second lower guard plate 6, and a third lower guard plate 8 are provided on the lower part of the side of the housing. The first lower guard plate 5 and the second lower guard plate 6 are sequentially arranged below the first front guard plate 2, and the third lower guard plate 8 is arranged below the second front guard plate 10.

[0021] This embodiment proposes a novel protective device that can effectively protect the old mining side space of the coal mining machine. The protection is reliable, easy to install and disassemble, and has a simple structure, solving the problems of easy failure and high failure rate of the original protection method.

[0022] The novel protective device provided in this embodiment is as follows: Figure 1 As shown, it includes a traction housing 1, a first front guard plate 2, a first upright plate 3, a first bottom support plate 4, a first lower guard plate 5, a second lower guard plate 6, an upright plate assembly 7, a third lower guard plate 8, a second bottom support plate 9, a second front guard plate 10, a second upright plate 11, a first top guard plate 12, and a second top guard plate 13.

[0023] The specific structure of the traction housing 1 is as follows: Figures 3-5 As shown, the system includes a first column 21, a second column 22, a third column 23, a first housing positioning pin hole 14, a first groove 15, a second housing positioning pin hole 16, a second groove 17, a third housing positioning pin hole 18, a third groove 19, and a fourth groove 20. The housing positioning pin holes increase the fixing reliability of the first upright plate 3, the upright plate assembly 7, and the second upright plate 11. The first upright plate 3, the upright plate assembly 7, and the second upright plate 11 are fixed to the traction housing 1 by positioning pins and screw sets, making the installation more secure. The three columns provide support for the corresponding protective plates. The traction housing 1 is equipped with a column structure to provide support for the corresponding protective plates, significantly increasing the structural strength. Each groove is used to embed the corresponding protective plate, improving the protective effect. The first front protective plate 2, the first lower protective plate 5, the second lower protective plate 6, the third lower protective plate 8, the second front protective plate 10, the first top protective plate 12, and the second top protective plate 13 are installed into the corresponding grooves, forming a completely enclosed space and greatly improving the protective effect.

[0024] Each protective plate is sunk into its corresponding groove, making it less susceptible to compression by coal or gangue, thus providing better protection.

[0025] The specific structure of the first upright plate 3 is as follows: Figures 6-8As shown, it is fixed to the traction housing 1 through the top threaded hole and the two pin holes on the left side. A U-shaped notch 73 is provided at the bottom to facilitate the installation of the first base plate 4, and the first base plate 4 is fixed through the bottom threaded hole. The small hole at the bottom of the pin hole on the left side of the first upright plate 3 is used for venting and to facilitate the installation and removal of the positioning pin.

[0026] The specific structure of the upright panel assembly 7 is as follows: Figures 9-11 As shown, the upright plate assembly 7 includes a top plate 77, support columns 78, support plates 79, and a bottom plate 80. One side of the top plate 77 is fixed to the traction housing 1, and the other end is connected to the support plate 79 through several support columns 78. One side of the support plate 79 is mounted on the bottom plate 80, and a reinforcing rib 72 is provided between the support plate 79 and the bottom plate 80. The reinforcing rib 72 is provided to improve the overall strength of the upright plate assembly 7. The upright plate assembly 7 is fixed to the traction housing 1 through a top threaded hole. The positioning pin holes of each upright plate are respectively installed to correspond to the positioning pin holes at the corresponding positions of the traction housing 1. A U-shaped notch 73 is provided to facilitate the installation of the first bottom support plate 4 and the second bottom support plate 9, and the first bottom support plate 4 and the second bottom support plate 9 are fixed through bottom threaded holes.

[0027] The specific structure of the second upright plate 11 is as follows: Figures 12-14 As shown, the second vertical plate 11 is fixed to the traction housing 1 via a top threaded hole and a left pin hole. A U-shaped notch 73 is provided at the bottom to facilitate the installation of the second bottom support plate 9, which is also fixed via a bottom threaded hole. The small hole at the bottom of the pin hole on the left side of the second vertical plate 11 is used for venting and to facilitate the installation and removal of the positioning pin.

[0028] The specific structure of the first base plate 4 is as follows: Figures 15-16 As shown, the cross-section is multi-step, with reinforcing ribs at the corners of the steps to enhance the overall strength of the first base plate 4. The first base plate 4 has flanged ends, which are respectively installed in the U-shaped notches 73 of the first upright plate 3 and the upright plate assembly 7, and fixed with corresponding screw sets, making installation convenient.

[0029] The specific structure of the second bottom support plate 9 is as follows: Figures 17-18 As shown, the cross-section is concave, and a reinforcing rib is provided at the bottom of the concave shape to enhance the overall strength of the second base plate 9. The two ends of the concave shape are flanged, and the flanged ends of the second base plate 9 are respectively installed in the U-shaped notches 73 of the second upright plate 11 and the upright plate assembly 7, and are fixed by corresponding screw groups, which facilitates installation.

[0030] It is feasible that the U-shaped notch 73 in the part forms a groove structure, and the first bottom support plate 4 and the second bottom support plate 9 can be easily pushed in, making installation convenient and maintenance easy.

[0031] In summary, this embodiment achieves good protection of the old mining area side space of the coal mining machine, greatly improves the reliability of the old mining area side protection device, avoids damage to related control components, increases the coal mining machine uptime, and can ensure the mine's efficient production.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
