The invention provides a method for assembling and disassembling a portal crane and an auxiliary supporting structure. The auxiliary supporting structure for assembling and disassembling the portal crane comprises steel supporting pieces, an upper hinged support, a lower hinged support and a concrete ground anchor, and the concrete ground anchor is poured and buried between two portal crane supporting legs of the portal crane. The lower hinged support is arranged on the concrete ground anchor, the two portal crane supporting legs are respectively provided with the upper hinged support, the twogroups of steel supporting pieces are respectively connected with the portal crane supporting legs, one end of each steel supporting piece is connected with the upper hinged support, the other end ofeach steel supporting piece is connected with the lower hinged support, and the steel supporting pieces and the portal crane supporting legs form a triangular stable structure. A steel supporting structure is adopted, and a steel support has certain rigidity and can be pulled and pressed, so that the steel support and the portal crane supporting legs can form the stable triangular structure without shaking, and the more safety of the portal crane in the assembling and disassembling process is ensured.
本发明提出一种用于门式起重机拼装与拆除的方法以及辅助支撑结构,所述用于门式起重机拼装与拆除的辅助支撑结构包括钢支撑件、上铰座、下铰座和混凝土地锚,所述混凝土地锚浇筑埋设于门式起重机的两门机支腿之间,所述下铰座设于所述混凝土地锚之上,所述的两门机支腿上分别设置有所述上铰座,所述钢支撑件有两组,分别与所述门机支腿连接,其一端连接所述上铰座,另一端连接所述下铰座,由所述钢支撑件、门机支腿构成三角稳定结构。本申请采用钢支撑结构,由于钢支撑具有一定的刚度,既能受拉也能受压,所以其与门机支腿可组成一个稳定的三角结构而不晃动,确保门机拼装与拆除过程更加安全。
