After jacking up, a rigid support platform must be used to fix and support the upper disc of the electric shovel. Four special rigid support platforms need to be fabricated. After the upper disc of the electric shovel is jacked up, a forklift is used to transport the rigid support platform to the relevant position to support the upper disc of the electric shovel, and then the jack rod of the hydraulic jack is retracted. The entire jacking operation procedure is cumbersome and the workload is large. Not only are there many types of special brackets and platforms with single functions, increasing the corresponding manufacturing costs, but there are also certain potential safety hazards. The general idea is as follows: A hydraulic jack support device for a synchronous jacking system includes a support body 1, an upper platform 2, a lower platform 3, and support columns 4. Through holes 6 and seat holes 7 are respectively provided on the upper platform 2 and the lower platform 3.

It is designed according to the shape of the hydraulic jack in the synchronous jacking system. A hydraulic jack 14 is provided inside the support body 1. Both groups of adjusting seats 8 fix the upper and lower ends of the hydraulic jack 14 through screws 9. The material is high-strength steel plate. The seat hole 7 and the through hole 6 have the same diameter and are concentric. The diameters of the through hole 6 and the seat hole 7 are slightly larger than the outer diameter of the hydraulic jack 14. There are four support columns 4, which are distributed at the four corners of the support body 1 and are respectively fixedly connected to the upper platform 2 and the lower platform 3.
