Turning method of double-guide-girder bridge girder erection machine
The invention discloses a turning method of a double-guide-girder bridge girder erection machine. The turning method comprises the following steps of Step 1, distributing and arranging an auxiliary middle supporting leg at the bottom of a main girder between a front supporting leg and a middle supporting leg; Step 2, jacking and lifting the bridge girder erection machine by the front supporting leg, the auxiliary middle supporting leg and a rear supporting leg, so that the middle supporting leg is disengaged, and the middle supporting leg is heightened; Step 3, contracting and disengaging thefront supporting leg, so that the auxiliary middle supporting leg, the rear supporting leg and the middle supporting leg support the bridge girder erection machine; Step 4, dismounting the front supporting leg, and hoisting the front supporting leg to a position behind the rear supporting leg by a hoisting crane, and installing the front supporting leg on the lower part of the main girder; and Step 5, dismounting a front auxiliary supporting leg, and hoisting the front auxiliary supporting leg to the rear end of the bridge girder erection machine through the hoisting crane, and installing thefront auxiliary supporting leg at the lower part of the main girder. Auxiliary equipment such as other cranes is not needed; in-situ turning of the bridge girder erection machine is realized; the turning work efficiency is comprehensively improved; and the turning method can be widely applied to the technical field of the bridge girder erection machine operation.
本发明公开了一种双导梁架桥机调头方法，包括：S1：在所述前支腿和所述中支腿之间的主梁底部布设辅助中支腿；S2：所述前支腿、所述辅助中支腿和所述后支腿顶升抬高架桥机，使所述中支腿脱空并增高所述中支腿；S3：收缩脱空所述前支腿，使所述辅助中支腿、所述后支腿和所述中支腿支撑架桥机；S4：拆卸所述前支腿并通过所述起重天车将所述前支腿吊运至所述后支腿后方，将所述前支腿安装于所述主梁下部；S5：拆卸所述前辅助支腿并通过所述起重天车将所述前辅助支腿吊运至架桥机后端，将所述前辅助支腿安装于所述主梁下部。本发明无需其他吊车等辅助设备，实现架桥机原地调头，调头工效全面提高，可广泛应用于架桥机作业技术领域。
