Front supporting leg mechanism of bridge girder erection machine and bridge girder erection machine
The invention provides a front supporting leg mechanism of a bridge girder erection machine and the bridge girder erection machine comprising the front supporting leg mechanism of the bridge girder erection machine. The front supporting leg mechanism of the bridge girder erection machine comprises an upper telescopic device, a lower telescopic device, an upper fixing device, a lower fixing device and a turnover driving device. The upper telescopic device comprises an upper outer column body and an upper inner column body; and the upper inner column body is used for relatively moving or relatively fixing in the upper outer column body. The lower telescopic device comprises a lower outer column body and a lower inner column body; and the lower inner column body is used for moving or fixing in the lower outer column body. The bottom of the upper telescopic device is hinged to the top of the lower telescopic device, the upper and lower fixing device is used for fixing the upper telescopic device and the lower telescopic device, and the turnover driving device is used for driving the lower telescopic device to turn over. The front supporting leg mechanism of the bridge girder erection machine and the bridge girder erection machine provided by the invention have a larger construction height adjusting range, and can meet girder erection construction under various special working conditions.
本发明提供了一种架桥机前支腿机构和包括所述架桥机前支腿机构的架桥机，所述架桥机前支腿机构包括上伸缩装置、下伸缩装置、上下部固定装置和翻转驱动装置。所述上伸缩装置包括上外柱体和上内柱体；所述上内柱体用于在所述上外柱体内部相对移动或相对固定。所述下伸缩装置包括下外柱体和下内柱体；所述下内柱体用于在所述下外柱体内移动或固定。所述上伸缩装置的底部和所述下伸缩装置的顶部铰接，所述上下部固定装置用于固定所述上伸缩装置和所述下伸缩装置，所述翻转驱动装置用于驱动所述下伸缩装置翻转。本发明提供的架桥机前支腿机构和架桥机具有更大的施工高度调节范围，能够满足多种特殊工况下的架梁施工。
