Embodiment 2
[0025] Embodiment 2, steel grid lifting equipment, the base 11 includes a rectangular support base 110, two inclined beams 111 are connected between the four corners inside the rectangular support base 110, and the intersection of the two inclined beams 111 is passed through a flange plate 113 is fixedly connected to the jack 12, with the axis of the jack 12 as the symmetric line, two mutually symmetrical jacking frame supports 112 are arranged on the two inclined beams 111, and the jacking frame supports 112 correspond to the standard section 21 of the lattice column up and down . The support 112 of the jacking frame is provided to support stably when the jack 12 falls back and when the jacking frame 2 raises the steel grid frame to the elevation, which not only facilitates the installation of the next lattice column standard section 21, but also facilitates the installation of the steel grid. The stable support after the top of the rack is raised to the elevation.

Embodiment 3
[0027] Embodiment 3, steel grid frame jacking equipment, each of the jacking frame supports 112 corresponds to the four bolt balls 210 below the lattice column standard section 21 up and down, and the jacking frame supports 112 and the bolt balls 210 are on top of each other The upper end surface of the joint is provided with a spherical groove having the same spherical radian as the bolt ball 210 . Setting spherical grooves can further ensure the stability of the support.
[0028] Other structures of this embodiment are the same as those of Embodiment 2.
