Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] As Figures 1-6 shown, the present utility model provides a subgrade edge protection device, including a bottom plate 1. A displacement block 4 is slidably connected to the top of the bottom plate 1. A displacement assembly is arranged on the top of the bottom plate 1, and the displacement assembly is used to drive the displacement block 4 to move. One end of the displacement block 4 is fixedly connected to a baffle 5. Parallel plates 20 are arranged on both sides of the baffle 5. A locking structure is arranged between the two parallel plates 20 and the baffle 5. A ground pile 10 is slidably connected to the inside of the bottom plate 1. Lifting assemblies are arranged on both sides of the displacement block 4 and on the top of the bottom plate 1, and the lifting assemblies are used to drive the ground pile 10 to move.

[0024] When using the subgrade edge protection device, first connect the parallel plate 20 to the baffle 5 through the locking structure. Then move the device body to the corresponding position, drive the ground pile 10 to move by using the lifting component, so that the bottom end of the ground pile 10 extends into the reserved positioning hole. Finally, push the baffle 5 close to and contact the subgrade edge through the displacement component, which facilitates corresponding adjustment according to the actual situation. At the same time, with the use of the ground pile 10, the stability of the device during use is improved.

[0025] As Figures 1-6 shown, the locking structure includes a first embedded plate 21 and a second embedded plate 22. The first embedded plate 21 and the second embedded plate 22 are fixedly connected to one side of the parallel plate 20. First slots 18 and second slots 19 are opened on both sides of the baffle 5. One ends of the first embedded plate 21 and the second embedded plate 22 respectively extend into the interiors of the first slot 18 and the second slot 19. A card slot 23 is opened on one side of the first embedded plate 21. A card block 17 is slidably connected to one side of the first slot 18. The inclined surface end of the card block 17 extends into the interior of the card slot 23. A function box 12 is fixedly connected to one side of the baffle 5. A slide plate 13 is slidably connected between the inner walls of the function box 12. One side of the slide plate 13 is fixedly connected to the card block 17. The other side of the slide plate 13 is fixedly connected to a connecting rod 14. One end of the connecting rod 14 extends outside the function box 12 and is fixedly connected to an adjustment block 16. A spring 15 is fixedly connected between the outer side of the connecting rod 14 and the inner wall of the function box 12 between the slide plate 13.

[0026] By inserting the first embedded plate 21 and the second embedded plate 22 on one side of the parallel plate 20 into the interiors of the first slot 18 and the second slot 19 respectively, one end of the first embedded plate 21 contacts the inclined surface of the card block 17, so that the card block 17 is stressed and moves into the interior of the function box 12, and the slide plate 13 moves in the function box 12 and compresses the spring 15. When the first embedded plate 21 is completely inserted into the first slot 18, the card block 17 extends into the interior of the card slot 23 under the influence of the elastic force of the spring 15, thus realizing the locking between the parallel plate 20 and the baffle 5.

[0027] As Figures 1-6As shown in the figure, the displacement component includes a fixed plate 2, which is fixedly connected to the top of the bottom plate 1. One side of the fixed plate 2 is rotatably connected to a threaded rod 3. The outer side of the threaded rod 3 is threadedly connected to a displacement block 4. A limiting groove 11 is provided inside the displacement block 4. One end of the threaded rod 3 is fixedly connected to a limiting plate 24, and the outer side of the limiting plate 24 is slidably connected to the inner wall of the limiting groove 11. A servo motor 7 is fixedly installed on one side of the fixed plate 2, and the output end of the servo motor 7 passes through the fixed plate 2 and is fixedly connected to the threaded rod 3. By driving the threaded rod 3 to rotate on one side of the fixed plate 2 by the servo motor 7, the displacement block 4 on the outer side of the threaded rod 3 moves on the top of the bottom plate 1, so as to conveniently adjust the position of the baffle 5 according to the actual use situation in cooperation with the fixing structure, thus facilitating the use of the roadbed edge protection device.

[0028] As Figures 1-6 shown in the figure, the lifting component includes two L-shaped plates 6, both of which are fixedly connected to the top of the bottom plate 1. An electric cylinder 8 is fixedly installed on the top of the L-shaped plate 6. The output end of the electric cylinder 8 passes through the L-shaped plate 6 and is fixedly connected to a connecting plate 9. The bottom of the connecting plate 9 is fixedly connected to a ground pile 10. By pushing the connecting plate 9 to move on the top of the bottom plate 1 by the electric cylinder 8, the ground pile 10 moves inside the bottom plate 1. By extending the bottom end of the ground pile 10 into the reserved positioning hole, the stability of the roadbed edge protection device during use is improved, and the use of the roadbed edge protection device is further facilitated.

[0029] Working principle: When using the roadbed edge protection device, first insert the first embedding plate 21 and the second embedding plate 22 on one side of the parallel plate 20 into the inside of the first slot 18 and the second slot 19 respectively, so that one end of the first embedding plate 21 contacts the inclined surface of the clamping block 17, causing the clamping block 17 to be stressed and move into the inside of the function box 12, so that the sliding plate 13 moves inside the function box 12 and compresses the spring 15. When the first embedding plate 21 is completely inserted into the first slot 18, the clamping block 17 extends into the inside of the card slot 23 under the influence of the elastic force of the spring 15, thus realizing the locking between the parallel plate 20 and the baffle 5. Then move the device body to the corresponding position, use the electric cylinder 8 to push the connecting plate 9 to move on the top of the bottom plate 1, so that the ground pile 10 moves inside the bottom plate 1. By extending the bottom end of the ground pile 10 into the reserved positioning hole, and finally drive the threaded rod 3 to rotate on one side of the fixed plate 2 by the servo motor 7, so that the displacement block 4 on the outer side of the threaded rod 3 moves on the top of the bottom plate 1, making the baffle 5 approach and contact the roadbed edge.
