[0023] Example: Figure 1-4 As shown, a SBE ground lifting system device comprises a bucket 1, and a lifting rod 2 is movably connected to the top surface of the bucket 1, so that the bucket 1 can be lifted by the full lifting system;

[0024] Two arc-shaped shells 3 are symmetrically arranged on the outer wall of the bucket 1, and two arc-shaped plates 4 are symmetrically arranged between the two arc-shaped shells 3. The two sides of the arc-shaped plates 4 are respectively inserted into the arc-shaped shells 3 on both sides and the arc-shaped plates 4 are movably connected to the arc-shaped shells 3. The top surfaces of the arc-shaped plates 4 and the arc-shaped shells 3 are provided with mounting components 5, and the mounting components 5 include a mounting plate 10, and the mounting plate 10 is arranged in an inverted concave shape. The mounting plate 10 is sleeved on the top surface of the bucket 1. The mounting plate 10 is located on the side wall of the inner cavity of the bucket 1 and is threadedly connected with a first bolt 11. The first bolt 11 penetrates the mounting plate 10 and is tightened on the inner wall of the bucket 1, so that the device can be easily fixed to the bucket 1, and the device can be adjusted according to the size of the bucket, thereby improving the versatility of the device.

[0025] The inner wall of the arc-shaped shell 3 is provided with an arc-shaped groove 24, and the side wall of the arc-shaped plate 4 is fixedly connected with a slide plate 25. The slide plate 25 is inserted into the arc-shaped groove 24 and the slide plate 25 is movably connected to the arc-shaped groove 24, so that the arc-shaped plate 4 can run stably in the arc-shaped shell 3.

[0026] Among them, the top surface of the arc-shaped shell 3 is threadedly connected with a second bolt 17 near both sides. The second bolt 17 passes through the top surface of the arc-shaped shell 3 and is pressed against the top surface of the arc-shaped plate 4, which can effectively improve the stability between the arc-shaped shell 3 and the arc-shaped plate 4;

[0027] The center of the side wall of the arc shell 4 and the arc plate 3 away from the bucket 1 is fixedly connected with a fixed shell 6, and a movable plate 7 is movably connected in the fixed shell 6. A spacing adjustment component 8 is arranged on the movable plate 7, and the spacing adjustment component 8 includes a threaded hole 12. A threaded hole 12 is opened on the side wall of the movable plate 7, and a threaded rod 13 is threadedly connected in the threaded hole 12. The end of the threaded rod 13 away from the movable plate 7 is movably connected to the fixed shell 6, and a bevel gear 14 is fixedly connected to the side wall of the threaded rod 13. A vertical shaft 15 is movably connected to the top surface of the fixed shell 6, and a rotating wheel 16 is fixedly connected to the top of the vertical shaft 15, and another bevel gear 14 is fixedly connected to the other end of the vertical shaft 15. The two bevel gears 14 are meshed with each other, so that the length of the movable plate 7 and the fixed shell 6 can be adjusted, and multi-point positioning and tightening between the inner wall of the shaft can be achieved, so as to improve the stability of the bucket 1 during the lifting operation;

[0028] A protective assembly 9 is provided on the side of the movable plate 7 away from the fixed shell 6. The protective assembly 9 includes a fixed plate 18. The side of the movable plate 7 away from the fixed shell 6 is fixedly connected to the fixed plate 18. The fixed plate 18 is symmetrically and movably connected with two movable rods 19. The two movable rods 19 are fixedly connected to the same side shell 20 at one end away from the bucket 1. A roller 21 is installed in the side shell 20. A spring 22 is sleeved on the movable rod 19. One end of the spring 22 is fixedly connected to the fixed plate 18, and the other end of the spring 22 is fixedly connected to the side shell 20. The spring 22 can adapt to the unevenness of the inner wall of the shaft, improve the stability of the bucket 1 lifting, and have good safety.

[0029] Among them, one end of the movable rod 19 away from the side shell 20 is fixedly connected to the limiting plate 23. The limiting plate 23 is circular and the diameter of the limiting plate 23 is larger than the diameter of the movable rod 19, so as to limit the movement of the movable rod 19 and facilitate the use of the device.

[0030] Working principle: When the device of the utility model is in use, the arc shell 3 is first pulled to make the arc plate 4 extend from the arc shell 3 to a suitable length, and then the mounting plate 10 is sleeved on the top surface of the bucket 1, and the first bolt 11 and the second bolt 17 are rotated. The fixing between the mounting plate 10 and the bucket 1 is achieved by the first bolt 11, and the positioning and fixing between the arc shell 3 and the arc plate 4 is achieved by the second bolt 17. Then, the rotating wheel 16 is rotated according to the inner diameter of the shaft, and the rotating wheel 16 drives the bevel gear 14 on the vertical shaft 15 to rotate, and the bevel gear 14 is used to drive the threaded rod 13 to rotate. The threaded rod 13 rotates in the threaded hole 12, and the movable plate 7 moves in the fixed shell 6, changing the length between the movable plate 7 and the fixed shell 6, so that the roller 21 is against the inner wall of the shaft, completing the installation and adjustment operation of the device. During use, when the bottom lifting system lifts the bucket 1, the roller 21 at multiple positions is used to limit the operation of the bucket 1, which can effectively reduce the shaking of the bucket 1 and improve the safety of construction.
