[0026] Example 1

[0027] Please see Figure 1-3 An adjustable hydraulic lifting frame includes a crossbeam 1 and a longitudinal beam 3. The dimensions of both the crossbeam 1 and the longitudinal beam 3 can be changed through a docking assembly 2. The docking assembly 2 includes a first beam segment 6 and a second beam segment 7. The first beam segment 6 is disposed at one end of the crossbeam 1 and / or the longitudinal beam 3, and the second beam segment 7 is disposed at the other end of the crossbeam 1 and / or the longitudinal beam 3. The second beam segment 7 can be inserted into the first beam segment 6 of the adjacent beam.

[0028] The second beam segment 7 is provided with an inner connecting segment 14, which can be inserted into the first beam segment 6;

[0029] An inner limiting ring 16 is provided inside the first beam segment 6.

[0030] A second reset groove 17 is provided in the first beam segment 6, and a reset block 13 is slidably connected in the second reset groove 17. A second spring 18 is provided between the reset block 13 and one end of the second reset groove 17. The reset block 13 is fixedly connected to the locking block 12, and the locking block 12 is slidably connected in the first beam segment 6.

[0031] The outer surface of the inner connecting section 14 is provided with a slot 15 corresponding to the slot block 12, and the slot block 12 can be engaged in the slot 15.

[0032] The outer surface of the first beam segment 6 is provided with a first reset groove 10, and an inner reset ring 9 is slidably connected in the first reset groove 10. A first spring 11 is provided between the inner reset ring 9 and one end of the first reset groove 10. The inner reset ring 9 is fixedly connected to a locking sleeve 8. The locking sleeve 8 is sleeved on the outside of the first beam segment 6, and the locking sleeve 8 is slidably connected to the first beam segment 6.

[0033] The inner wall of the locking sleeve 8 can abut against the locking block 12.

[0034] A lifting platform 4 is provided on the crossbeam 1, and a hydraulic jack is provided on the lifting platform 4.

[0035] The working principle and beneficial effects of the above scheme are as follows:

[0036] This application optimizes existing fixed-length crossbeams and longitudinal beams into several sets of beam segments that can be spliced ​​together. The shorter crossbeams 1 or longitudinal beams 3 are spliced ​​together by the connecting component 2, so that their dimensions can be set according to different plates to be adjusted, thereby adapting to the use of plates of different specifications.

[0037] During the reconnection, the locking sleeve 8 is moved, causing the locking block 12 to lose its restraint and pop out under the action of the second spring 18. Then, a set of second beam segments 7 is inserted into the first beam segment 6 of another set. The locking sleeve 8 is released and reset under the action of the first spring 11, compressing the locking block 12 so that the locking block 12 overcomes the action of the second spring 18 and is locked in the locking groove 15, completing the connection of the two sets of beams and increasing the length of the beam.

[0038] Example 2

[0039] Please see Figure 4 Based on Embodiment 1, a fixed platform 5 is provided on the longitudinal beam 3, and a fixed component is provided on the fixed platform 5.

[0040] The fixing assembly includes a support rod 19, on which a fixing frame 20 is rotatably connected. The fixing frame 20 is in the form of... The fixed frame 20 is threaded to one end with a screw 21, and the end of the screw 21 located inside the fixed frame 20 is rotatably connected to an upper fixed plate 23. The other end of the fixed frame 20 is provided with a lower fixed plate 24.

[0041] A handle 22 is fixedly connected to one end of the screw 21 located outside the fixing frame 20.

[0042] The working principle and beneficial effects of the above scheme are as follows:

[0043] The plate side is fixed in the fixed frame 20. Rotate the handle 22 to drive the screw 21 to move down. The upper fixed plate 23 and the lower fixed plate 24 are used to fix the plate side firmly. When the hydraulic jack of the lifting platform 4 lifts and performs reverse deformation, the plate side will form a certain angle with the fixed platform 5. The setting of the fixed frame 20 rotating and connected to the support rod 19 can make the reverse deformation of the plate side fit the deformation angle more closely.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
