Abstract
The utility model relates to a lifting device. A jacking tower for large steel structure building constructions comprises a lifting strength bearing bottom frame, a lifting cross-shaped beam, a lifting hydraulic jack, a top supporting frame and a standard knot. The lifting strength bearing bottom frame comprises a bottom steel beam, two stand columns, a top steel beam and a through hole. Two holes are formed at two ends of the bottom steel beam. The two stand columns are inserted into the two holes. The top steel beam is arranged at the upper ends of the two stand columns. The through hole is formed in the middle of the top beam. The lifting cross-shaped beam is arranged between the top steel beam and the bottom steel beam, two horizontal ends of the lifting cross-shaped beam are connected with the stand columns through the holes, and a through hole is formed in the middle of the lifting cross-shaped beam. The lifting hydraulic jack is arranged on the upper surface of the top steel beam, and is connected with threaded steel. The threaded steel penetrates through the through hole in the top steel beam and the through hole in the center of the lifting cross-shaped beam in sequence. Underboarding and a nut are respectively arranged at the two ends of the threaded steel. The top supporting frame comprises a beam and a vertical rod with two ends connected, and the side face of the lower end of the vertical rod is connected with two ends of the top beam. The upper end of the standard knot is connected with the lower end of the vertical rod of the top supporting frame, and the side face of the lower end of the standard knot is connected with the lifting cross-shaped beam. According to the jacking tower for the large steel structure building constructions, assembled quality is guaranteed, and working efficiency is improved.
Description
Technical field
The utility model relates to lifting appliance, relates in particular to large-scale steel structure building operations lifting appliance.
Background technology
In the large public building that adopts steel work, special building, disposable or accumulate stage by stage the jack-up construction technology and be employed more and more, at present main what adopt is to change on top and as the requisite jacking frame of this job practices, this method work high above the ground is many, potential safety hazard is large, and assembly and disassembly is inconvenient.
