The invention discloses a portal crane rigid bracket convenient for transition, and relates to the technical field of hoisting mechanical equipment. The rigid support comprises two supporting frames which are symmetrically supported at the bottom of a main beam foundation section in a splayed mode and are in an A shape, a cross brace connected between the middles of the two supporting frames in a flange and bolt matching mode, and an inclined brace with the two ends hinged to the positions between the upper portions of the two supporting frames and the bottom of the foundation section respectively to form a triangular supporting structure. The supporting frame is of an A-shaped supporting structure formed by connecting the bottoms of a main supporting leg and an auxiliary supporting leg in a hinged mode and connecting the middles of the main supporting leg and the auxiliary supporting leg with a transverse connecting rod in a flange and bolt matching mode. According to the invention, the two A-shaped support frames are used as a main body and are quickly connected through the cross rod to be assembled into a rigid support, and each A-shaped support frame is formed by movably connecting the main support leg, the auxiliary support leg and the cross connecting rod, so that quick disassembly and quick assembly can be realized, the assembly or disassembly time is shortened, the transition efficiency of the crane is improved, and transition and transportation are facilitated.
本发明公开一种便于转场的门式起重机刚性支架,涉及起重机械设备的技术领域。所述刚性支架包括呈外八字型对称方式支撑在主梁基础节底部、自身呈A字型的两片支撑架,通过法兰和螺栓配合方式连接在两片支撑架中部之间的横撑,两端分别铰接在两片支撑架的上部与基础节底部之间、形成三角支撑结构的斜撑;支撑架是由主支腿和副支腿底部通过铰接相连、中部通过法兰和螺栓配合方式连接横连杆后形成的A字型支撑结构。本发明是以两片A字型的支撑架为主体通过横杆快连后组装成一个刚性支架,而A字型的支撑架本身是由主支腿、副支腿、横连杆活连接而成,能够实现快速拆卸和快速组装,缩短安装或拆卸时间,提高起重机的转场效率,便于转场和运输。
