[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 As shown, the protective cover for a mining hydraulic support includes a base 1, a support 2, a side plate 3, a top plate 4, a hydraulic cylinder 5, and a protective component 6. One end of the base 1 is hinged to one end of the support 2, the other end of the support 2 is hinged to one end of the side plate 3, and the other end of the side plate 3 is hinged to one end of the top plate 4. The side plate 3 prevents coal blocks falling from the side from impacting the support, thus improving safety. The hydraulic cylinder 5 is fixedly installed on the base 1, and the movable end of the hydraulic cylinder 5 is hinged to the top plate 4. The hydraulic cylinder 5 is used to limit the relative position of the base 1 and the top plate 4. The protective component 6 is set around the hydraulic cylinder 5. One end of the protective component 6 is fixedly installed on the base 1, and the other end of the protective component 6 is fixedly connected to the movable end of the hydraulic cylinder 5. The protective component 6 can completely enclose the hydraulic cylinder 5, reducing the impact of coal blocks falling from the side and rear, and improving production safety.

[0031] like Figure 2As shown, the base 1 is set inside the mine. A connecting frame 11 is set at one end of the base 1. The connecting frame 11 is used to connect the bracket 2. The base 1 is provided with an installation groove 12. The hydraulic cylinder 5 and the protective component 6 are fixedly installed in the installation groove 12. The installation groove 12 can quickly locate the installation position of the hydraulic cylinder 5 and the protective component 6, reduce manual labor, and improve work efficiency.

[0032] like Figure 3 As shown, the protective component 6 includes a first protective cover 61, a second protective cover 62, and an end cap 63. One end of the first protective cover 61 is fixedly connected to the base 1. The inner ring of the first protective cover 61 is slidably sleeved on the outer periphery of the second protective cover 62. One end of the second protective cover 62 is provided with a detachable end cap 63. By setting the slidable first protective cover 61 and the second protective cover 62, the hydraulic cylinder 5 can be adapted to different extension and retraction states, ensuring the smooth operation of the hydraulic support and reducing potential safety hazards in production.

[0033] like Figure 4 As shown, the inner diameter of the first protective cover 61 is larger than the outer diameter of the second protective cover 62. The lower periphery of the first protective cover 61 and the second protective cover 62 are respectively provided with lower limit blocks 611, and the upper inner walls of the first protective cover 61 and the second protective cover 62 are respectively provided with upper limit blocks 612. The lower end of the upper limit block 612 of the first protective cover 61 abuts against the upper end of the lower limit block 611 of the second protective cover 62. The lower limit block 611 and the upper limit block 612 are used to limit the relative position of the first protective cover 61 and the second protective cover 62. The lower limit block 611 and the upper limit block 612 can prevent the first protective cover 61 and the second protective cover 62 from separating, thereby reducing potential safety hazards in production.

[0034] like Figure 4 As shown, the first protective cover 61 and the second protective cover 62 are also provided with a plurality of anti-collision blocks 613, and the plurality of anti-collision blocks 613 are evenly distributed along the inner circumference of the first protective cover 61 and the second protective cover 62, and each anti-collision block 613 is provided with anti-slip texture 6131. ​​By setting anti-collision blocks 211 and anti-slip texture 2111, the protective effect of the protective component 6 on the hydraulic support can be improved, the direct wear of the protective component 6 on the hydraulic support caused by external collision can be reduced, and the production safety can be improved.

[0035] like Figure 4 and Figure 5As shown, the first protective cover 61 is a ring structure. The first protective cover 61 also includes a left protective unit 614 and a right protective unit 615. The left protective unit 614 and the right protective unit 615 are arranged opposite each other, and the two ends of the left protective unit 614 are detachably connected to the two ends of the right protective unit 615. The left protective unit 614 includes a left protective plate 6141, a first step 6142 and a first buckle 6143. The two ends of the left protective plate 6141 are respectively provided with the first step 6142. A plurality of first buckles 6143 are provided on one side of the first step 6142, and the plurality of first buckles 6143 are evenly distributed along the axial direction of the first step 6142. The detachably connected left protective unit 614 and right protective unit 615 enable quick installation, reduce manual labor and increase work efficiency.

[0036] like Figure 6 As shown, the right protective unit 615 includes a right protective plate 6151, a second step 6152, and a slot 6153. The two ends of the right protective plate 6151 are respectively provided with a second step 6152 that matches the first step 6142, and the second step 6152 is provided with a slot 6153 that matches the first buckle 6143. The slot 6153 is used to limit the relative position of the first buckle 6143. By setting the second step 6152 that matches the first step 6142, the mating surface can be better sealed, reducing dust intrusion and reducing production safety hazards. By setting the slot 6153 that matches the first buckle 6143, quick docking and installation can be achieved, reducing manual labor.

[0037] like Figure 7 As shown, the end cap 63 includes a left cap body 631 and a right cap body 632. The left cap body 631 and the right cap body 632 have the same structure and are arranged opposite each other. The left cap body 631 includes a body 6311 and a positioning protrusion 6312 at its lower end. The outer periphery of the positioning protrusion 6312 is slidably connected to the inner ring of the second protective cover 62. The lower end of the positioning protrusion 6312 is provided with a second buckle 6313. The second buckle 6313 is used to limit the relative position of the second protective cover 62 and the body 6311. One side of the body 6311 is provided with a positioning groove 6314. The positioning groove 6314 is used to avoid the connecting ring of the moving end of the hydraulic cylinder 5. By setting the second buckle 6313, the upper end of the second buckle 6313 abuts against the lower end of the upper limit block 612, which can fix the end cap 6 to the upper end of the second protective cover 62, realize the quick connection between the second protective cover 62 and the moving end of the hydraulic cylinder, and reduce manual labor.

[0038] Working process of protective covers for mining hydraulic supports:

[0039] The base 1 is fixed inside the mine shaft and is connected to the support 2 via a connecting frame 11. The support 2 is hinged to the side plate 3 and the top plate 4 in sequence. A hydraulic cylinder 5 and a protective assembly 6 are installed in the mounting groove 12 of the base 1. The movable end of the hydraulic cylinder 5 is hinged to the top plate 4 to limit their relative positions. In the protective assembly 6, one end of the first protective cover 61 is fixed to the base 1. Its left protective unit 614 and right protective unit 615 are detachably connected via a first buckle 6143 and a slot 6153. The second protective cover 62 is slidably sleeved inside the first protective cover 61. The two are connected by a lower limit block 611 and an upper limit block 62. 2. The relative positions are defined. The end cap 63 at one end of the second protective cover 62 is connected to the second protective cover 62 through the positioning protrusion 6312 and the second buckle 6313. At the same time, it is sleeved on the periphery of the connecting ring 51 of the movable end of the hydraulic cylinder 5 through the positioning groove 6314. When the hydraulic cylinder 5 is working, its movable end drives the top plate 4 to move. At the same time, the protective component 6 extends and retracts with the movable end of the hydraulic cylinder 5. The first protective cover 61 and the second protective cover 62 slide relative to each other. The anti-collision block 613 and the anti-slip texture 6131 play a buffering and stabilizing role. The whole system realizes the protection of the hydraulic cylinder 5 and the linkage with the hydraulic support.
