[0002] In the current field of mechanical lifting technology, cylinder lifting and hinged mechanical dead point lifting structures are two common implementation methods. However, both technologies have certain limitations.

[0003] Although the cylinder-type lifting can achieve a relatively smooth lifting action, its lifting reaction force is limited by the output force of the cylinder itself, resulting in a relatively low load-bearing capacity and difficulty in meeting large load or high-demand application scenarios. In addition, the stroke and speed control of the cylinder are also relatively complex, which increases the difficulty and cost of operation.

[0004] On the other hand, although the hinged mechanical dead point lifting structure is compact, it is difficult to design, manufacture and maintain due to its complex mechanical structure. The complex mechanical structure not only increases the manufacturing cost, but also easily leads to misoperation or jamming due to external interference during operation, affecting the stability and reliability of the lifting. At the same time, the mechanical lifting position is fixed and single, which makes it difficult to meet the diverse lifting needs, limiting its application scope. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See attached Figure 1 --2. The utility model provides a supporting jacking device, comprising:

[0028] A lifting platform 100, wherein the lifting platform 100 is provided with a through hole, and the lifting platform 100 is provided with a plurality of flexible abutment blocks 110 on the peripheral side of the through hole;

[0029] A lifting mechanism 200, the lifting mechanism 200 is used to drive the lifting platform 100 to move in the vertical direction;

[0030] The abutment mechanism 300 includes a flexible abutment member 310 and a counter-pushing member 320, wherein the counter-pushing member 320 is used to drive the abutment member 310 to move upward along the axis of the through hole;

[0031] The limiting mechanism 400 moves in a horizontal direction;

[0032] When the abutting member 310 moves from above to abut, the limiting mechanism 400 can move horizontally to abut below the abutting member 310 .

[0033] Based on the above technical features, the lifting platform 100 is used to receive the object, and the flexible abutment block 110 is provided to achieve flexible abutment and lifting of the workpiece; the lifting mechanism 200 drives the lifting platform 100 to achieve horizontal lifting of the received object, and a through hole is provided in the middle of the abutment block 110, so that the abutment mechanism 300 can move from the top through the through hole to achieve abutment on the object, and the surrounding side of the object abuts on the abutment block 110, and the abutment mechanism 300 further supports the object, and reduces the rigid abutment on the workpiece through the flexible abutment member 310 to avoid deformation of the workpiece, and abuts on the bottom of the abutment member 310 through the limiting mechanism 400 to achieve limiting of the abutment member 310, and further provides vertical support force for the abutment member 310, thereby improving the pressure resistance, and has a simple structure and flexible lifting support capability for the support reaction force position of the workpiece.

[0034] Furthermore, the limiting mechanism 400 includes a latch head 410 for abutment, the top of the latch head 410 is an inclined plane, the abutment member 310 includes an abutment plane 311 abutting against the latch head 410, and the abutment plane 311 is parallel to the top of the latch head 410. By setting the latch head 410 at an angle, the stroke can be changed according to different workpieces, so that a height difference can be generated in the height direction, and a small range of products of different heights can be compatible.

[0035] Specifically, the abutment mechanism 300 includes a first abutment unit 330 and a second abutment unit 340 which are arranged at intervals, and the first abutment unit 330 can be close to or away from the second abutment unit 340 in the horizontal direction.

[0038] Specifically, the fixing frame 600 is symmetrically provided with the jacking mechanism 200 to improve the jacking stability of the jacking platform 100 .

[0039] In this embodiment, the inclination angle of the abutment plane 311 is 5°, so as to avoid the impact of supporting stability caused by excessive lifting height due to too large an angle, and to avoid the inability to significantly achieve stroke adjustment for different heights due to too small an angle.

[0040] Furthermore, the abutting planes 311 are located on both sides of the abutting member 310 , and the latch heads 410 abut against the abutting members 310 accordingly, further improving the stable abutment between the abutting member 310 and the latch heads 410 .
