The invention provides a mounting method for assembling a quay crane superstructure, which comprises the following steps of: S1, jacking a front girder by using a plurality of hydraulic flatbeds, and withdrawing a jig frame; s2, the hydraulic flat car is moved to transfer the front girder to a preset position, and an upper hinged support of the front girder falls into a guide block of a rear girder; and S3, the hydraulic flat car located on the sea side is lifted, so that the part, located on the sea side, of the front girder is higher than the part, located on the land side, of the front girder, and it is ensured that a lower hinged shaft of the front girder does not make contact with a lower hinged support of the rear girder. Only two hydraulic flat cars are adopted for cooperative operation, and operation is easy and convenient; the requirements on workers are greatly reduced, and various cost investments are controlled; the installation method is not limited by sites or influenced by weather, and the working efficiency is obviously improved.
本发明提供了一种岸桥上部结构装配的安装方法,其包括以下步骤:S1、使用多个液压平板车顶起前大梁,撤出胎架;S2、移动所述液压平板车将所述前大梁转运至预先设定的位置,将所述前大梁的上铰支座落入后大梁的导向块内;S3、升高位于海侧的所述液压平板车,使所述前大梁处于并保持海侧的部分高于陆侧的部分,确保所述前大梁的下铰轴与所述后大梁的下铰座未接触。本发明仅需采用两台液压平板车配合作业,操作简便;工作人员需求大幅减少,各项成本投入得到控制;安装方法不受场地限制及天气影响,工作效率明显提高。
