The invention discloses a three-dimensional portal girder crane for quickly assembling a spherical hinge module trolley. The three-dimensional portal girder crane comprises a bailey track beam, the spherical hinge module trolley, an assembled portal, a module walking lifting trolley and a hydraulic and electrical control system. The four sets of spherical hinge type module trolleys can rotate around the centers of the spherical hinge type module trolleys respectively and can walk on linear or curve rails under the guiding effect of steel rails, the assembled portal is composed of standard modularized steel pipe main columns and bailey beams, the portal and the four module lifting trolleys can be assembled according to needs, and the assembled portal is formed by assembling the standard modularized steel pipe main columns and the standard modularized bailey beams. The module walking lifting trolley can be a wheel track type module walking lifting trolley or a hydraulic sliding type module walking lifting trolley, four lifting points achieve four-change-three stress through steel wire penetrating and winding, heavy objects are lifted together, all the lifting hooks can achieve lifting action in a three-dimensional space, multi-degree-of-freedom accurate alignment of the lifted heavy objects in the high-altitude three-dimensional space can be well achieved, and the lifting effect is good. The steel ropes at the four lifting points are all used for vertically lifting heavy objects, and the height of the portal can be reduced under the working condition of the same lifting height.
本发明公开了一种球铰模块台车快速拼装三维门式架梁起重机,包括:贝雷轨道梁、球铰式模块台车、拼装式门架、模块式行走起重台车、液压及电气控制系统。本发明通过设置四组球铰式模块台车各自可绕自身中心旋转,在钢轨的导向作用下,可在直线或曲线轨道过行走,拼装式门架由标准模数化的钢管主柱和贝雷梁组成,可依据需要拼装成不同尺寸的门架,四台模块起重台车,可为轮轨式模块行走起重台车或液压滑移式模块行走起重台车,四吊点通过钢丝穿绕实现四变三受力,共同抬吊重物,各吊钩均可在三维空间实现起吊动作,能较好实现起吊重物在高空三维空间多自由度精确对位,四吊点钢绳均为垂直吊装重物,在同等起吊高度的工况下可降低门架高度。
