The winding assembly is located above the adjusting support assembly, and the opening direction of the through slot 7 is parallel to the square telescopic strip 4.

[0031] During operation, the angle adjustment of the existing slope protection device for civil construction is inconvenient, the adjustment speed is slow, and the protection area cannot be adjusted according to the use situation, resulting in inconvenience in use and a small protection area.

After use, the rolling jacking assembly is controlled to be recovered. After the rolling jacking assembly is recovered, the coil 28 will be re-reeled in the winding assembly under the action of the winding assembly, and the angle adjustment effect can be achieved. Compared with traditional slope protection devices, the angle adjustment is more convenient and the protection area is larger, which effectively improves the convenience of use of the slope protection device.

[0033] The rolling lifting assembly includes three interlocking grooves 14, a lifting rod 20 and two motors 22. The lifting rod 20 is horizontally arranged on the side of the swing guard plate 2 facing the bottom plate 1.

When in use, the two motors 22 are controlled to operate. When the two motors 22 operate, they will respectively drive the two rotating threaded rods 23 to rotate. When the two rotating threaded rods 23 rotate, they will drive the lifting rod 20 to move upward under the limit of the guide groove 19. When the lifting rod 20 moves upward, it will drive the three lifting rods 16 to slide upward in the three engaging grooves 14 at the same time under the limit of the limiting ribs 17. When the three lifting rods 16 extend upward, they will drive the lifting rollers 18 at their tops to lift the coil 28 upward. , and one end of the coil 28 is fixed on the fixing bar 29. Under the lifting of the lifting roller 18, the coil 28 wound on the rotating sleeve 26 will be extended to the winding drum 24. When it needs to be recovered, the lifting rod 20 is controlled to move downward, so that the lifting rod 20 drives the three lifting rods 16 to retract into the three fitting grooves 14, so that the lifting roller 18 drops to the end surface of the swing guard plate 2. At this time, under the action of the volute spring sheet 27, the rotating sleeve 26 will rewind the coil 28 into the winding drum 24 again. When the device is used, the fixed threaded rod 31 is rotated and set in the No. 2 threaded hole 30, and the fixed threaded rod 31 is inserted into the soil layer under the bottom plate 1 after passing through the No. 2 threaded hole 30. The function of adjusting the protection area is achieved, which effectively improves the stability of the slope protection device.

[0039] Working principle: in the initial state, the spring 13 will always push the end of the swing plate 10 provided with the inclined surface block 11 into the inclined surface slot 8, so that the inclined surface block 11 is stuck in the inclined surface slot 8. When in use, the bottom plate 1 is placed on the ground, and then the angle between the swing guard plate 2 and the bottom plate 1 is adjusted according to the slope of the tunnel. When adjusting, the swing guard plate 2 is directly flipped onto the slope of the tunnel. When the swing guard plate 2 is flipped, it will drive the square telescopic strip 4 to extend from the hollow square tube 3, and the square telescopic strip 4 will extend to the swing guard plate in the hollow square tube 3. The plate 2 slides and extends. When the swing guard plate 2 is flipped open, the inclined surface of the inclined surface block 11 fits with the inner inclined surface of the inclined surface slot 8, and when the square telescopic strip 4 extends from the hollow square tube 3, the inclined surface block 11 will be sequentially inserted into the evenly arranged inclined surface slots 8, and the swing plate 10 will swing on the first fixed shaft 9. After being adjusted to the right position, the square telescopic strip 4 cannot be retracted into the hollow square tube 3 under the clamping of the inclined surface slot 8, and when the swing guard plate 2 is flipped over, the ends of the hollow square tube 3 and the square telescopic strip 4 will respectively pass through the first rotating shaft 9. The movable seat 5 and the second rotating seat 6 rotate on the bottom plate 1 and the swing guard plate 2, and then the angle between the swing guard plate 2 and the bottom plate 1 is fixed by extending the hollow square tube 3 and the square telescopic strip 4 with a fixed length. After use, the swing plate 10 is moved toward the side of the fixed plate 12 to move the inclined surface block 11 out of the inclined surface slot 8, and the square telescopic strip 4 is retracted into the hollow square tube 3. At this time, the swing guard plate 2 can be turned over and retracted for the next protective use. When adjusting the protective area according to the usage, the rolling jacking group is controlled The component is lifted in a direction parallel to the swing guard plate 2. When the rolling lifting component is lifted, the coil 28 wound in the winding component will be extended, so that the protection area of ​​the swing guard plate 2 will be increased after the coil 28 is extended.

Compared with traditional slope protection devices, the angle adjustment is more convenient and the protection area is larger, which effectively improves the convenience of use of the slope protection device.

[0040] In the initial state, the volute spring sheet 27 will always twist the rotating sleeve 26, so that the rotating sleeve 26 will reel the coil 28 into the reel 24. When in use, the two motors 22 are controlled to operate. When the two motors 22 operate, they will respectively drive the two rotating threaded rods 23 to rotate. When the two rotating threaded rods 23 rotate, they will drive the lifting rod 20 to move upward under the limit of the guide groove 19. When the lifting rod 20 moves upward, it will drive the three lifting rods 16 to slide upward in the three fitting grooves 14 respectively under the limit of the limit ribs 17. When the three lifting rods 16 extend upward, they will drive the lifting roller 18 at the top to lift the coil 28 upward. One end of the coil 28 is fixed on the fixing bar 29. The lifting of the lifting roller 18 will extend the coil 28 wound on the rotating sleeve 26 to the winding drum 24. When it needs to be recovered, the lifting rod 20 is controlled to move downward, so that the lifting rod 20 drives the three lifting rods 16 to retract into the three interlocking grooves 14, so that the lifting roller 18 drops to the end surface of the swing guard plate 2. At this time, under the action of the spiral spring sheet 27, the rotating sleeve 26 will rewind the coil 28 into the winding drum 24 again. When the device is used, the fixed threaded rod 31 is rotated and set in the No. 2 threaded hole 30, and the fixed threaded rod 31 is inserted into the soil layer under the base plate 1 after passing through the No. 2 threaded hole 30. The cooperation achieves the effect of adjusting the protection area, which effectively improves the stability of the slope protection device.
