[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] An embodiment provided by the utility model: Figure 1 As shown, a safety protection support for coal mining includes a central support 1, a support member 2, a side support 3, a rotating support seat 4, a fixed support seat 5 and a dust prevention mechanism 6.
[0026] like Figure 1 and Figure 3 As shown, the upper and lower parts of the central support 1 are respectively fixedly connected to the side support 3 through the support member 2, and a rotating support seat 4 is arranged below the side support 3 at the bottom, and the rotating support seat 4 is rotatably connected to the side support 3 through a rotating connector 41. The rotating support seat 4 is provided with two groups, one group is located at the bottom of the support body 31 away from the second limit end 33, and the other group is located at the bottom of the second limit end 33. The bottom of the side support 3 is close to the second limit end 33 and is provided with a fixed support seat 5. When in use, the two groups of rotating support seats 4 are rotated to a state perpendicular to the side support 3, and the rotating support seats 4 can support the device on the ground, and the fixed support seat 5 consolidates the support in the middle part of the protective support, thereby improving the overall stability of the protective support, and is not easy to tip over in windy weather, thereby ensuring the safety of the protective support when in use. After use, the rotating support seat 4 is rotated back to a state parallel to the side support 3, saving the space occupied by the protective support and facilitating transportation.
[0027] like Figure 4 and Figure 5As shown, the central bracket 1 includes a first telescopic member 11 and a first limiting end 12, one end of the first telescopic member 11 is arranged inside the central bracket 1, and the other end is fixedly connected to the first limiting end 12. The side bracket 3 includes a bracket body 31, a second telescopic member 32 and a second limiting end 33, one end of the second telescopic member 32 is arranged inside the bracket body 31, the second telescopic member 32 is slidably connected to the bracket body 31, and the second limiting end 33 is installed at the other end of the second telescopic member 32. When in use, the first limiting end 12 and the second limiting end 33 are moved outward, and the first telescopic member 11 and the second telescopic member 32 extend outward from the center bracket 1 and the bracket body 31 respectively, so that the overall width of the protective bracket can be changed. According to the area of on-site protection, by adjusting the width of the protective bracket, it is easier to connect the protective brackets at different positions, thereby improving the efficiency of the use and operation of the protective bracket. After use, the first telescopic member 11 and the second telescopic member 32 are pushed to the inside of the central bracket 1 and the bracket body 31 respectively, and the first limiting end 12 and the second limiting end 33 are respectively pressed against the end edges of the central bracket 1 and the bracket body 31, so that the protective bracket is retracted, the overall volume is reduced, storage space is saved, and it is also convenient for transportation.
[0028] The side bracket 3 is provided with a dustproof mechanism 6, such as Figure 6 and Figure 7 As shown, the dustproof mechanism 6 includes a dustproof connecting frame 61 of the main part of the bracket, a dustproof connecting frame 62 of the telescopic part, a dustproof curtain 63 and a magnetic strip 64. The dustproof connecting frame 61 of the main part of the bracket and the dustproof connecting frame 62 of the telescopic part are both connected with the dustproof curtain 63. The dustproof connecting frame 61 of the main part of the bracket includes a first left connecting frame 611 and a first right connecting frame 612, and the dustproof connecting frame 62 of the telescopic part includes a second left connecting frame 621 and a second right connecting frame 622. The outer sides of the first left connecting frame 611 and the first right connecting frame 612 and the second left connecting frame 621 and the second right connecting frame 622 are all in the same plane, which is convenient for the connection between the two sets of dustproof curtains 63; when the dustproof curtain 63 is in the open state, the outer sides of the first left connecting frame 611 and the first right connecting frame 612 are respectively flush with the two ends of the bracket body 31, and the outer side of the second left connecting frame 621 is flush with the outer side of the second limit end 33, which is convenient for the connection of the dustproof curtain 63 between adjacent protective brackets.
[0029] like Figure 6As shown, the dustproof connecting frame 61 of the main part of the support and the dustproof connecting frame 62 of the telescopic part are both provided with a dustproof curtain 63, and the dustproof curtain 63 is in a foldable form, wherein the two ends of the dustproof curtain 63 of the dustproof connecting frame 61 of the main part of the support are respectively fixedly connected to the first left connecting frame 611 and the first right connecting frame 612, and the two ends of the dustproof curtain 63 of the telescopic part of the dustproof connecting frame 62 are respectively fixedly connected to the second left connecting frame 621 and the second right connecting frame 622. The protective support not only has the function of safety protection, but also the installation of the dustproof curtain 63 can isolate the space on both sides of the protection, play a role in blocking a large amount of coal dust in the air during the coal mining stage, and protect the respiratory health of the workers outside the protection area.
[0030] like Figure 1 , Figure 5 and Figure 7 As shown, the first left connecting frame 611 is fixedly connected to the bracket body 31. The first right connecting frame 612 is slidably connected to the bracket body 31 in a transverse direction. A first slide groove 311 is provided on a single side surface of the bracket body 31. The first right connecting frame 612 and the second right connecting frame 622 have similar structures and both include pulley components. The pulley components include a first pulley 6121 and a second pulley 6221. The first pulley 6121 of the first right connecting frame 612 is located in the first slide groove 311. When the width of the protective bracket does not need to be extended during use, it is only necessary to open the dust curtain 63 on the bracket body 31. The first left connecting frame 611 at one end of the dust curtain 63 is fixed, and the first right connecting frame 612 at the other end is moved to slide to one side on the first slide groove 311 of the bracket body 31. The dust curtain 63 is fully unfolded to achieve the effect of isolating the two sides of the bracket body 31.
[0031] like Figure 1 , Figure 5 and Figure 7As shown, the two ends of the second left connecting frame 621 are respectively fixedly connected to the upper and lower groups of second telescopic members 32.

The second telescopic member 32 is provided with a second slide groove 321 on the same side as the slot of the bracket body 31, and the second pulley 6221 of the second right connecting frame 622 is located in the second slide groove 321. When the width of the protective bracket is extended during use, the dust curtain 63 on the bracket body 31 is unfolded, and the dust curtain 63 on the second telescopic member 32 also needs to be opened. The second left connecting frame 621 at one end of the dust curtain 63 is fixed, and the second right connecting frame 622 at the other end is moved to slide to one side on the second slide groove 321 of the second telescopic member 32. The width of the corresponding dust curtain 63 is unfolded according to the length of the second telescopic member 32, so as to achieve the effect of isolating the two sides of the second telescopic member 32. When there is no large amount of coal powder in the air, the two sets of dust curtains 63 can also be folded to the original position so that the protection bracket does not block the field of vision, making it easy to observe the inner and outer areas of the protection.
[0032] like Figure 8 As shown, magnetic strips 64 are respectively provided on the left side of the first left connecting frame 611, the right side of the first right connecting frame 612, the left side of the second left connecting frame 621, and the right side of the second right connecting frame 622. The two adjacent groups of protective brackets are connected by the magnetic strips 64 on the right side of the first right connecting frame 612 and the left side of the second left connecting frame 621; the inside of each group of protective brackets is connected by the magnetic strips 64 on the left side of the first left connecting frame 611 and the second right connecting frame 622, so that the dust curtain 63 can be connected and reach a closed state, thereby improving the effect of isolating coal dust.
