Problems solved by technology
[0003] At present, the jacking device in construction machinery is generally composed of a hydraulic cylinder and a support plate, and the support plate is pushed on the structure that needs to be lifted. However, when the existing jacking device lifts a special-shaped structure, Since the surface of the special-shaped structure is often uneven, it is not easy to clamp and fix it, and there is a problem of poor jacking stability

The invention belongs to the technical field of engineering machinery, particularly relates to a jacking device suitable for a special-shaped structure. Aiming to solve the problem that an existing jacking device is not easy to stably jack a special-shaped structure, the following scheme is provided, the jacking device comprises a supporting base, and the outer wall of the center of the top of the supporting base is connected with a first hydraulic cylinder through a bolt; and a first supporting plate is arranged at the top of the first hydraulic cylinder, supporting columns are connected to the outer walls of the four corners of the top of the first supporting plate through bolts, and the outer walls of the tops of the four supporting columns are connected with the same supporting top plate through bolts. The jacking device suitable is firstly placed at the bottom of the special-shaped structure, then a second hydraulic cylinder is contracted, fixing clamping plates are made to rotate towards the interior of a fixing groove, then the first hydraulic cylinder jacks the first supporting plate, the bottom of the special-shaped structure is made to be located between the two fixing clamping plates, and the two fixing clamping plates achieve the wrapping effect on the bottom of the special-shaped structure; and the supporting area of the special-shaped structure is increased, and the jacking stability of the special-shaped structure is improved.
