The invention discloses a semi-circular girder rail-mounted gantry crane general assembly method, and relates to the technical field of rail-mounted gantry crane general assembly. The method comprises the steps of track arrangement; a cart walking mechanism is arranged; hoisting the rigid leg side door frame and the flexible leg side door frame; hoisting the girder assembly; inclined struts are hoisted; hoisting an electrical room and a high-voltage room; hoisting the trolley assembly; installing a cable reel; the accessories are jacked and installed; and debugging the whole machine. The method has the advantages that the opening size of an upper opening is measured again before the rigid leg side door frame and the flexible leg side door frame are hoisted, the cart walking mechanism and the rigid leg side door frame are positioned and connected after positioning, the girder camber is measured again before the girder assembly is hoisted, the girder assembly is hoisted in place in a stable state, positioning is accurate during installation, the installation precision is guaranteed, and the installation efficiency is improved. All the parts are installed step by step according to a proper installation sequence, the balance stability is good during hoisting and installation, and the safety risk is reduced; when the trolley assembly is hoisted, the placement position is accurate, and the final assembly efficiency is improved.

    本发明公开了一种半圆形大梁轨道吊总装方法,它涉及轨道吊总装技术领域。步骤为:轨道布置;布置大车行走机构;吊装刚腿侧门框及柔腿侧门框;吊装大梁组件;吊装斜撑;吊装电气房、高压房;吊装小车总成;安装电缆卷盘;顶升安装附属件;整机调试。本发明的优点在于:吊装刚腿侧门框及柔腿侧门框前复测上口开档尺寸,定位后将大车行走机构与刚腿侧门框定位连接,大梁组件吊装前复测大梁拱度,大梁组件处于平稳状态进行吊装到位,安装时定位准确,安装精度得到保障,各部件按照合适的安装顺序逐步安装,吊装和安装时平衡稳定性好,降低安全风险;吊装小车总成时,放置位置准确,提升总装效率。
