The invention discloses an installation method suitable for a large-span high-lift truss type gantry crane, and belongs to the field of hoisting machinery. The mounting method comprises the following steps of A, fixing the movable bottom cross beam, B, splicing the main beam, C, fixing the main beam, D, mounting the lifting electric hoist, E, hinging the tops of the supporting legs, F, lifting the main beam, G, fixing the tops of the supporting legs, H, integrally hoisting and translating, and I, fixing the bottom ends of the supporting legs. According to the method, the assembling sequence of the supporting legs and the lifting electric hoist in a traditional gantry crane mounting method is changed, and ground operation is achieved in the assembling process of the supporting legs and the main beam, the assembling process of the lifting electric hoist and the main beam and the final large assembling process of the gantry crane; ground splicing replaces traditional high-position splicing, a series of complex high-position stable auxiliary devices and measures can be omitted, the installation process is greatly simplified, the installation efficiency is improved, the equipment requirement is reduced, the operation risk of high-altitude splicing is avoided and reduced, the assembly safety of the gantry crane is greatly improved, and safe assembly is achieved.

    本发明公开一种适用于大跨度高扬程桁架式龙门吊的安装方法,属于起重机械领域。所述安装方法步骤如下:A、固定移动式底横梁,B、拼接主梁,C、固定主梁,D、安装起升电动葫芦,E、铰接支腿顶部,F、起吊主梁,G、固定支腿顶部,H、整体吊装平移,I、固定支腿底端。本发明改变了龙门吊传统安装方法中支腿及起升电动葫芦的拼装顺序,使支腿与主梁的拼装、起升电动葫芦与主梁的拼装、龙门吊最后的大组装过程均实现地面化作业,以地面拼装代替传统高位拼装能够省去一系列复杂的高位稳定辅助装置及措施,大大简化了安装过程,提高安装效率,减少设备需求,规避及降低了高空拼装的作业风险,大大提高龙门吊的组装安全性,实现安全组装。
