[0026] 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.

[0027] The utility model provides a technical solution:

[0028] A soft rock slope protection device comprises a base plate 1 and further comprises:

[0029] Angle adjustment components, such as Figure 1 and Figure 2 As shown, the angle adjustment mechanism includes a diagonal support assembly 8 and an adjustment base 2, and one end of the adjustment base 2 is connected to the drive shaft 6. Specifically, a side plate 3 is provided on the other side of the upper end of the base plate 1, and a worm wheel 4 and a worm 5 are built into the adjustment base 2, and one end of the worm wheel 4 is connected to the drive shaft 6. One end of the worm 5 is connected to a handwheel 13. One end of the worm 5 is connected to the handwheel 13. When the handwheel 13 is manually turned, the worm 5 is driven to rotate, and the worm 5 drives the worm wheel 4 meshing therewith to rotate. When the worm wheel 4 rotates, it drives the drive shaft 6 to rotate, and the drive shaft 6 drives the protective plate 7 to rotate relative to the base plate 1, and the inclination angle of the protective plate 7 relative to the base plate 1 is adjusted. When performing protection, the inclination of the protective plate 7 is adjusted accordingly according to the inclination of the soft rock slope, so that the overall protection device is suitable for slopes with different inclinations, thereby improving the flexibility during use. The structure of the worm wheel 4 and the worm 5 has a certain self-locking property, that is, the worm 5 can easily rotate the worm wheel 4, but the worm wheel 4 cannot rotate the worm 5. Relying on the self-locking property, the protective plate 7 can maintain a certain inclination and remain motionless to provide protective support. The angle adjustment method of the protective plate 7 is simple, and on-site construction and assembly are convenient for soft rock slopes with different inclination angles.

[0030] A protective plate 7 is welded and fixed on the driving shaft 6, and the diagonal brace assembly 8 is telescopically located on one side of the protective plate 7. The diagonal brace assembly 8 is used to telescope to adjust the angle of the protective plate 7.

[0031] Protection components, such as Figure 1 As shown, the protection assembly includes an extension plate 9, a vertical plate 10 and a protection net 12. The extension plate 9 is built in the protection plate 7, and the extension plate 9 is slidably connected to the protection plate 7. Vertical plates 10 are arranged on both sides of the top of the extension plate 9. A roller 11 is arranged between the two vertical plates 10, and the protection net 12 is wound on the roller 11. By rotating the roller 11, the protection net 12 is retracted and released. The diagonal brace assembly 8 is located on one side of the protection plate 7, and the diagonal brace assembly 8 plays a role of diagonal support to improve the stability of the protection device.

[0032] The extension plate 9 is slidably connected to the protective plate 7, and a tightening seat 14 is provided on the outer side of the protective plate 7. The extension plate 9 and the protective plate 7 are fixed by a first tightening screw 15. When adjusting the extension plate, first loosen the first tightening screw 15 to release the fastening force between the extension plate 9 and the protective plate 7. At this time, the extension plate 9 can slide relative to the protective plate 7, and a certain external force is applied to the extension plate 9, so that the extension plate 9 can be pulled out from the inside of the protective plate 7 to extend the total height of the protective plate 7. After the adjustment is completed, tighten the first tightening screw 15 to tighten it. According to the structure of the soft rock slope, the extension length of the extension plate 9 can be adjusted, that is, the total height of the protective plate 7 can be adjusted, which is suitable for soft rock slopes of different heights, and further improves the flexibility during use.

[0033] like Figure 1 As shown, a protective net 12 is wound on the roller 11, which together constitute a net protection structure, and is located at the top of the protective device. When the protective plate 7 and the extension plate 9 are unable to protect the upper part of the soft rock slope, the protective net 12 is stretched, and the upper part of the soft rock slope is protected by the protective net 12, thereby increasing the protection area of ​​the protective device, thereby improving the protection effect of the protective device. The protective net 12 forms surface protection for the protected area, thereby preventing the collapse of rock and soil from falling, and playing a role in slope protection.

[0034] like Figure 3 As shown, the diagonal brace assembly 8 includes a sleeve 16 and a slide rod 17, and one end of the slide rod 17 is slidably embedded in the interior of the sleeve 16, and the sleeve 16 and the slide rod 17 are fixed by a second tightening screw 18. After the second tightening screw 18 is loosened, the slide rod 17 can slide relative to the sleeve 16. A certain external force is applied to the slide rod 17, and the protruding length of the slide rod 17 relative to the sleeve 16 can be adjusted, that is, the total length of the diagonal brace assembly 8 can be adjusted. After the adjustment is completed, the second tightening screw 18 is tightened to fix it, which makes it convenient to adjust the length of the diagonal brace assembly 8.

[0035] like Figure 3As shown, the other end of the slide rod 17 is connected to the U-shaped seat 19, and a fixed seat 20 is arranged on the U-shaped seat 19, and the fixed seat 20 is rotatably connected to the U-shaped seat 19 via a rotating shaft. Figure 1 and Figure 3 As shown, a mounting block 21 is provided on the outer side of the protective plate 7, and the mounting block 21 is fixed to the fixing seat 20 by screws.

[0036] like Figure 3 As shown, the diagonal support assembly 8 includes a base 22, a connecting block 23 is welded and fixed to one end of the sleeve 16, and the connecting block 23 is rotatably connected to the base 22 via a rotating shaft, as shown in FIG. Figure 3 and Figure 4 As shown, one end of the diagonal brace assembly 8 is fixedly connected to the mounting block 21 of the protective plate 7 through the fixing seat 20, and the other end of the diagonal brace assembly 8 is fastened to the ground. The protective plate 7 is reinforced by the diagonal brace assembly 8, and the stability of the protective device is improved by relying on the self-locking property of the worm gear 4 and the worm 5 and the diagonal support of the diagonal brace assembly 8.

[0037] like Figure 1 As shown, a first mounting groove 24 is formed on the base plate 1, a second mounting groove 25 is formed on the base 22, the base plate 1 is fastened to the ground via anchor bolts, and the base 22 of the diagonal brace assembly 8 is fastened to the ground via anchor bolts.

[0038] like Figure 1 As shown, the extension plate 9 is composed of a frame 26, and the frame 26 includes a frame and a wire mesh. By using the frame and the wire mesh, the slope is protected, the weight is reduced, and transportation and installation are convenient.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
