[0036] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model is a support device for phosphate mining, comprising a support assembly 1, on which a mounting frame 2 is arranged;

The lower end of the outer wall of the first limiting rod 121 is provided with an external thread, and the bottom end of the first limiting rod 121 passes through the surface of the U-shaped plate 11 and is threadedly sleeved with a first limiting nut 122, and the first limiting nut 122 is located below the fixing plate 13, and the buffer spring 12 is sleeved on the outer wall of the first limiting rod 121. The two ends of the buffer spring 12 are respectively fixedly connected to the facing surfaces of the U-shaped plate 11 and the fixing plate 13, and the U-shaped plate 11 and the fixing plate 13 are movably installed by the first limiting rod 121 and the first limiting nut 122, and the movement distance of the two is limited, thereby limiting the deformation of the buffer spring 12 to avoid elastic failure of the buffer spring 12;

[0038] The end surface of the fixing plate 13 is penetrated by sleeves 141 at equal intervals. The sleeves 141 penetrate the fixing plate 13 longitudinally. Meanwhile, the inner side surface of the sleeves 141 is provided with internal threads. The inner thread of the sleeves 141 is connected with a first threaded rod 142. One end of the first threaded rod 142 is movably connected with the L-shaped plate 14. The other end of the first threaded rod 142 is fixedly connected with a first knob 143.

[0039] The L-shaped plate 14 is respectively located at the front and rear ends of the fixed plate 13. Second limiting rods 144 are welded on both sides of the vertical arms of the L-shaped plate 14. The other ends of the second limiting rods 144 penetrate the end surface of the fixed plate 13 and are threadedly sleeved with second limiting nuts 145. The second limiting rods 144 and the second limiting nuts 145 are arranged to limit the movement of the L-shaped plate 14 and make the movement of the L-shaped plate 14 more stable.

[0040] Support columns 15 are fixedly connected to both sides of the lower surface of the horizontal support arm of the U-shaped plate 11. The inner column 152 is matched with the internal gap of the outer column 151 in the support column 15. The arrangement of the outer column 151 and the inner column 152 realizes the support of the U-shaped plate 11 and other structures. A first threaded hole 153 is provided above the end surface of the outer column 151, and a plurality of groups of second threaded holes 154 are provided on the end surface of the inner column 152 at equal intervals in the longitudinal direction. The internal thread of the first threaded hole 153 is connected with a first bolt 155. One end of the first bolt 155 passes through the first threaded hole 153 and is threadedly connected to the second threaded hole 154. Inside, the first threaded hole 153 and the second threaded hole 154 are used to install the first bolt 155, and the installation between the outer column 151 and the inner column 152 is realized by the setting of the first bolt 155. The bottom end of the outer column 151 is welded with a bottom plate 156, and the bottom plate 156 is used to support the bottom end of the outer column 151. Ribs 157 are fixedly connected to both sides of the upper surface of the bottom plate 156. One side of the rib 157 is fixedly connected to the outer walls of both sides of the outer column 151.

[0041] Based on the above arrangement, when in use, firstly, the outer column 151 is installed at a designated position in the phosphate mine through the bottom plate 156, and the height of the support column 15 is adjusted according to the height of the mine, the first bolt 155 is screwed so that the first bolt 155 moves out from the inside of the second threaded hole 154, and an external force is applied to the inner column 152 so that the inner column 152 slides relative to the outer column 151, and when the inner column 152 moves to the designated position, the first bolt 155 is screwed again so that one end of the first bolt 155 moves again to the inside of the second threaded hole 154, thereby completing the adjustment of the installation height of the installation frame 2;

[0042] Next, the two sides of the bottom of the installation frame 2 are placed on the fixed plates 13 located on both sides of the inside of the mine, and the first knob 143 is turned. The first knob 143 drives the first threaded rod 142 to rotate relative to the sleeve 141, and under the action of the threaded connection between the sleeve 141 and the first threaded rod 142, the first threaded rod 142 drives the L-shaped plate 14 to move toward the fixed plate 13, and the installation frame 2 is clamped on the upper surface of the fixed plate 13 through the L-shaped plate 14, completing the installation of the support device;

[0043] Finally, when there are falling rocks at the top of the mine, the falling rocks fall into the installation frame 2 and exert an external force on the fixed plate 13 through the installation frame 2, so that the fixed plate 13 drives the first limiting rod 121 to move relative to the U-shaped plate 11, and compresses the buffer spring 12 during the movement of the fixed plate 13, and then with the cooperation of the buffer spring 12 and the first limiting rod 121, the external force exerted on the fixed plate 13 and the installation frame 2 is absorbed, thereby realizing the support work of the mine.

[0044] See also Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, a protective component 3 is disposed inside the installation frame 2;

[0045] The U-shaped frames 21 in the installation frame 2 are respectively located on both sides, and the lateral arms of the U-shaped frame 21 are gap-fitted with connecting rods 22.

[0046] The winding rollers 31 in the protection assembly 3 are rotatably connected to one side of the inner part of the U-shaped frame 21, and a protection net 32 ​​is wound on the winding rollers 31. The front and rear ends of the winding rollers 31 are fixedly connected to a rotating shaft 33. The other end of the rotating shaft 33 passes through the front and rear end surfaces of the U-shaped frame 21 and is welded with a rotating disk 34. A plurality of positioning holes 341 are arranged in a circular array on the end surface of the rotating disk 34, and a limiting member 35 is arranged on one side of the rotating disk 34.

[0047] The mounting blocks 351 in the limiting member 35 are respectively fixedly connected to the other side of the back surface of the horizontal support arm of the U-shaped frame 21, and the second threaded rod 352 is rotatably connected inside the mounting block 351. A sliding groove is provided on the mounting block 351, and the second threaded rod 352 is rotatably installed in the sliding groove of the mounting block 351. The other end of the second threaded rod 352 passes through the end surface of the mounting block 351 and is fixedly connected to the second knob 353.

A positioning column 355 is welded on one side of the facing surface of the movable plate 354, and the other end of the positioning column 355 is clearance-fitted in the interior of the positioning hole 341. The movable plate 354 is used to drive the positioning column 355 to move, and the clearance fit between the positioning column 355 and the positioning hole 341 is used to limit the rotation of the turntable 34, thereby limiting the rotation of the winding roller 31;

[0048] Based on the above arrangement, when the protection area of ​​the protection net 32 ​​needs to be adjusted, the second knob 353 is first rotated, and the second knob 353 drives the second threaded rod 352 to rotate synchronously, and under the action of the threaded connection between the second threaded rod 352 and the moving plate 354, the moving plate 354 moves, so that the positioning column 355 on the moving plate 354 moves out from the inside of the positioning hole 341;

[0049] Then, the second bolt 23 is screwed, so that one end of the second bolt 23 moves out from the inside of the fourth threaded hole 221, and an external force is applied to the U-shaped frame 21, so that the U-shaped frame 21 moves in opposite directions or towards each other. During the movement of the U-shaped frame 21, the U-shaped frame 21 applies an external force to both ends of the protective net 32, so that the winding roller 31 rotates, and the protective net 32 ​​is rolled up and unrolled by the rotation of the winding roller 31, so that the length of the protective net 32 ​​is adjusted;

[0050] Finally, the second bolt 23 is screwed again so that one end of the second bolt 23 is threadedly connected to the inside of the fourth threaded hole 221 again, thereby completing the adjustment of the protection area.
