DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0020] As shown in the accompanying drawings Figure 1 As shown in the accompanying drawings Figure 5 The safety protection device for mine mining is provided with an adjusting protection assembly, which can adjust the protection area according to actual needs, so that the mine mining safety protection has wider adjustability, and the specific structure of the adjusting protection assembly is as follows.

[0021] In the technical solution, as shown in the accompanying drawings Figure 1 As shown in the accompanying drawings Figure 2As shown, the sliding frame 2 slides on one side of the support frame 1. The adjusting screw 3 is rotatably connected to the inner wall of the sliding frame 2, and the outer wall of the adjusting screw 3 is provided with an adjusting protective assembly. The adjusting protective assembly includes a sleeve block 4 threadedly connected to the outer wall of the adjusting screw 3, and the sleeve block 4 is slidably connected to the sliding frame 2. A strip plate 5 is fixedly installed on one side of the sleeve block 4, and the strip plate 5 is fixedly connected to the support frame 1 and slidably connected to the support groove frame 6. One end of the adjusting screw 3 extends to the outside of the sliding frame 2 and is fixedly connected to a rotating cap 7. Multiple sliding columns 8 are slidably connected to the inner wall of the support groove frame 6. The sliding frame 2 is fixedly connected to the support groove frame 6, and the outer wall of the sliding frame 2 and the inner wall of the support groove frame 6 are smooth surfaces. The outer wall of the sleeve block 4 and the inner wall of the sliding frame 2 are both smooth surfaces. The vertical cross-section of the multiple sliding columns 8 is circular, and the outer walls of the multiple sliding columns 8 are all smooth surfaces.

[0022] In this technical solution, as shown in the appendix Figure 1 As shown, a limiting block 9 is fixedly connected to one end of each sliding column 8. The vertical cross-section of the multiple limiting blocks 9 is polygonal, so that the sliding column 8 can drive the limiting block 9 to move to the left. The limiting block 9 performs a limiting operation with the support groove 6. A base plate 10 is fixedly installed on the lower surface of the support groove 6, and an mounting plate 11 is fixedly connected to the lower surface of the support frame 1. Multiple mounting holes 12 are opened on the inner walls of the base plate 10 and the mounting plate 11, so that bolts can be inserted into the mounting holes 12, so that the mounting plate 11 and the base plate 10 can be connected and installed.

[0023] In use, the protective device for mining safety in this technical solution works by rotating the rotating cap 7, which drives the adjusting screw 3 to rotate. The adjusting screw 3 rotates inside the sliding frame 2, causing the sleeve block 4 to move to the left under the action of the threaded transmission force. The sleeve block 4 then moves the strip 5 to the left, and the strip 5 moves to the left along the inner wall of the support slot frame 6. The strip 5 also moves the support frame 1 to the left, which in turn moves multiple sliding columns 8 to the left. The sliding columns 8 move the limiting block 9 to the left, and the support frame 1 moves the mounting plate 11 to the left. This creates a gap between the support frame 1 and the support slot frame 6, and a gap between the mounting plate 11 and the base plate 10. The distance between the support frame 1 and the support slot frame 6 can be adjusted according to the actual support range, providing greater adjustability. The sliding columns 8 move the limiting block 9, which is positioned at the limiting position of the support slot frame 6. This makes the distance between the support frame 1 and the support slot frame 6 adjustable, making adjustable support more convenient. After adjustment, insert the bolt into the mounting hole 12 to complete the insertion and installation of the mounting plate 11 and the base plate 10.

[0024] In this technical solution, as shown in the appendix Figure 3 - Appendix Figure 5As shown, the two sides of the sliding frame 2 are provided with arc-shaped blocks 13, and the two arc-shaped blocks 13 are fixedly connected with the support frame 1; one end of each arc-shaped block 13 is fixedly installed with an arc-shaped support plate 14, and the arc-shaped block 13 and the arc-shaped support plate 14 are slidably connected with the support groove frame 6; the inner wall of the arc-shaped block 13 is fixedly installed with an arc-shaped support strip 18, and the inner wall of the arc-shaped support strip 18 is fixedly installed with a support block 15; one side of the support block 15 is fixedly connected with an inclined block 16, and the other side of the support block 15 is fixedly installed with a reinforcing inclined block 17; the inclined block 16 and the reinforcing inclined block 17 are fixedly connected with the arc-shaped support strip 18. The reinforcing inclined block 17 and the inclined block 16 are fixedly connected with the arc-shaped support strip 18, and the reinforcing inclined block 17 and the inclined block 16 are symmetrically arranged about the support block 15; the reinforcing inclined block 17, the inclined block 16 and the support block 15 are fixedly connected with the support frame 1.

[0025] When the mine mining safety protection device is used, the support frame 1 drives the two arc-shaped blocks 13 to move left, the arc-shaped blocks 13 drive the arc-shaped support plates 14 to move left, and the arc-shaped blocks 13 and the arc-shaped support plates 14 move left along the inner wall of the support groove frame 6; at the same time, the arc-shaped blocks 13 drive the arc-shaped support strips 18 to move, the arc-shaped support strips 18 drive the support blocks 15 to move, and the support blocks 15 drive the inclined blocks 16 and the reinforcing inclined blocks 17 to move synchronously, so that the support frame 1 and the support groove frame 6 can be adjusted, and the support frame 1 and the support groove frame 6 are stably reinforced and supported, and the reinforcing and supporting force after adjustment is better.

[0026] The above only describes preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
