[0022] Example 1, combined with Figure 1 Explanation:

[0023] A hydraulic lifting device includes a lifting support assembly 1 and a hydraulic drive assembly 2. The lifting support assembly 1 includes a lifting plate 3, a base support plate 4, a sliding column 5, and a fixing bolt 6. The hydraulic drive assembly 2 includes a hydraulic jack 8 and a drive box 7. The sliding column 5 is fixedly installed on the base support plate 4. The lifting plate 3 is fixed to the sliding column 5 by the fixing bolt 6 and the fixing nut 31. The hydraulic jack 8 is fixedly installed in the drive box 7. The hydraulic drive assembly 2 is slidably installed in the lifting support assembly 1.

[0024] With this setup, the lifting support assembly 1 is driven by the hydraulic drive assembly 2. In the lifting support assembly 1, the lifting plate 3 is slidably mounted on the sliding column 5 and fixed by the fixing bolt 6 to keep the height of the lifted part constant, which facilitates reinforcement or foundation backfilling and leveling. The hydraulic jack 8 is fixed in the drive box 7. After the lifting plate 3 is fixed, when the lifting support assembly 1 can provide support for the lifted part on its own, the hydraulic jack 8 can be moved out to drive another set of lifting support assemblies 1, reducing the cost and weight of the device.

[0025] Example 2, based on Example 1, combined with... Figure 2 and Figure 3 Explanation:

[0026] The lifting plate 3 includes an insertion plate 11, a sliding plate 12, and a support plate 13. The insertion plate 11 and the sliding plate 12 are connected by an inclined plate, with the sliding plate 12 being higher than the insertion plate 11. The sliding plate 12 and the support plate 13 are also connected by an inclined plate, with the support plate 13 being higher than the sliding plate 12. The sliding plate 12 has a sliding hole 14 and a fixing hole 15 on its side, penetrating both the sliding plate 12 and the sliding hole 14. A fixing bolt 6 is fixedly installed in the fixing hole 15 by a fixing nut 31. One side of the insertion plate 11 is angled 17, and the bottom of the support plate 13 has a lifting groove 16. A hydraulic seat 19 is provided at one end of the base support plate 4, with impact seats 20 fixedly installed on both sides of the hydraulic seat 19. The other end of the base support plate 4 is angled 21. Multiple sets of through holes 18 are provided on the sliding column 5.

[0027] With this setup, the device is inserted between the ground and the lifted part by striking the impact seat 20, simplifying the operation. The insertion plate 11, sliding plate 12 and support plate 13 on the lifting plate 3 are fixedly connected by an inclined plate, so that a height difference is formed between the insertion plate 11 and the support plate 13. A hydraulic jack 8 is set up, and the lifting plate 3 slides and is lifted along the sliding column 5 through the cooperation between the sliding hole 14 and the sliding column 5. The lifting plate 3 is fixed by the fixing hole 15, the through hole 18 and the fixing bolt 6, so that the height of the lifted part remains unchanged.

[0028] Example 3, based on Example 2, combined with Figure 4 Explanation:

[0029] A handle 10 and an inspection cover 9 are fixedly installed on the drive box 7. A drive motor 23 is fixedly installed inside the drive box 7. The output end of the drive motor 23 is fixedly connected to a hydraulic pump 24 through a coupling 25. One end of the hydraulic pump 24 is connected to a hydraulic oil tank, and the other end of the hydraulic pump 24 is fixedly connected to a hydraulic jack 8. The hydraulic jack 8 is fixedly installed in a hydraulic fixed chamber 26. The hydraulic fixed chamber 26 is fixedly installed on one side of the drive box 7. A control panel 30 is fixedly installed on the top of the drive box 7. The control panel 30 is electrically connected to the drive motor 23.

[0030] With this configuration, the user can disassemble the hydraulic drive assembly 2 via the handle 10, inspect the internal devices via the inspection cover 9, and electrically connect and control the drive motor 23 via the control panel 30, making it convenient to control the height of the hydraulic jack 8. The drive motor 23 drives the hydraulic pump 24 via the coupling 25, and the hydraulic pump 24 drives the hydraulic jack 8.

[0031] Example 4, based on Example 3, combined with Figure 5 Explanation:

[0032] A connecting seat 22 is fixedly installed on the support plate 13. A connecting hole 27 is opened on the connecting seat 22. A connecting rod 28 is movably installed in the adjacent connecting hole 27. A level 29 is installed on the connecting rod 28.

[0033] With this setup, when leveling the lifted part is required, the connecting rod 28 is placed between the connecting holes 27, the height of multiple sets of lifting plates 3 is adjusted, and the level is achieved in conjunction with the level 29.

[0034] The working principle of this utility model is as follows: By inserting the insertion plate 11 and the bottom support plate 4 between the lifted part and the ground, the lifting plate 3 is lifted by the hydraulic jack 8. The lifting plate 3 is fixed by the cooperation between the fixing bolt 6 and the sliding column 5, keeping the height of the lifted part unchanged, which facilitates the reinforcement of the lifted part or the backfilling of the foundation. The detachable hydraulic drive component 2 saves the working space and the load on the workers when multiple sets of hydraulic lifting devices are needed. When the lifted part needs to be leveled, the multiple lifting support components 1 can be connected by the connecting rod 28. The level 29 on the connecting rod 28 assists in the leveling work. This utility model has a simple structure and significant effect. The lifting plate 3 is lifted by the hydraulic jack 8, and the lifting plate 3 is fixed by the sliding column 5 and the fixing bolt 6, which fixes the lifting effect, stabilizes the position of the lifted part, and facilitates subsequent work.
