Floor slab climbing crane shockproof structure

Abstract

This invention relates to a floor-climbing crane seismic isolation structure, primarily erected on a building steel frame. The building steel frame comprises multiple beams and columns, and multiple steel beams supporting each beam and column. The building steel frame defines multiple floors, each composed of various steel beams. The structure mainly includes: at least two foundation steel beam groups, multiple frame-supported steel beams, multiple lead-core rubber bearings, multiple dampers, multiple floor-climbing frame supports, and a crane beam frame. Each foundation steel beam group includes two foundation steel beams, and these foundation steel beam groups are located on steel beams at different floors. Each foundation steel beam has its two ends supported by steel beams. The steel beams of the frame base are respectively supported on the adjacent foundation steel beams at both ends. Each lead-core rubber bearing is set at both ends of each frame base steel beam and located between the foundation steel beams. Each damper is set at one end of the frame base steel beam and the other end of the beam and column. Each stair climbing frame base is set on each frame base steel beam and defines a through-hole. The crane beam is passed through each through-hole and connected to the stair climbing frame base. Through the above structure, the overall crane beam can be improved to ensure that the crane installed on the crane beam will not suffer structural damage (breakage or deformation) due to excessive shaking when subjected to strong shaking.
