The invention discloses a gantry crane structure and an installation method, and belongs to the technical field of building construction, the gantry crane structure comprises a cart running mechanism moving along a track, a lower seat beam supported by the cart running mechanism, supporting legs installed on the lower seat beam, a main beam bridge erected on the supporting legs, and a crane car running along the main beam bridge; wherein the lower seat beam is provided with a rolling guide mechanism and a guide rope guide mechanism, the rolling guide mechanism is in rolling contact with the supporting legs, and the guide rope guide mechanism drags the supporting legs and further guides the supporting legs to the supporting leg installation positions of the lower seat beam, so that alignment of the supporting legs in the installation process is achieved. According to the method, the mounting positions of the supporting legs of the gantry crane and the supporting legs of the lower seat beam can be quickly and accurately aligned, the mounting efficiency and the alignment precision are improved, the swinging of the supporting legs in the hoisting process is small, and the method is very suitable for mounting construction of the gantry crane in windy areas such as mountainous area tunnels and ports.
本发明公开了一种龙门吊结构及安装方法,属于建筑施工技术领域,龙门吊结构包括:沿轨道运动的大车运行机构、被大车运行机构支撑的下座梁、安装至下座梁的支腿、架设在支腿上的主梁桥架、沿主梁桥架运行的起重车;其中,所述下座梁设置有滚动导向机构和引绳导向机构,滚动导向机构与支腿滚动接触,引绳导向机构牵引支腿,进而将支腿引导至下座梁的支腿安装位置,而实现安装过程中支腿的对位。本发明可以使得龙门吊的支腿与下座梁的支腿安装位置快速准确对位,提高安装效率和对位精度,且支腿吊装过程中摆动小,非常适合多风区域如山区隧道和港口等的龙门吊安装施工。
