The earthwork transfer bridge for the large foundation pit comprises symmetrically-arranged bridge bodies, each bridge body comprises symmetrically-arranged lower beam frames, a plurality of triangular steel frames are installed above the lower beam frames, an upper beam frame is fixedly connected to the tops of the triangular steel frames, the lower beam frames of the two bridge bodies are connected through a connecting mechanism, and a lifting bucket is arranged between the two bridge bodies. The two sides of the lifting bucket are connected with the lifting mechanism through steel ropes, the lifting mechanism is fixedly installed at the end, close to the connecting mechanism, of the upper beam frame, the stand columns are symmetrically and fixedly installed between the lower beam frame and the upper beam frame and fixedly installed at the ends, close to the connecting mechanism, of the lower beam frame and the upper beam frame, and the material guiding mechanism is fixedly installed between the stand columns. The distance between the two bridge bodies is adjustable, erection on foundation pits with different spans is facilitated, meanwhile, the supporting plates on the two sides can be conveniently dumped through the arrangement of the lifting hoppers and the lifting mechanisms, the earthwork transferring efficiency is improved, in addition, earthwork can be prevented from being scattered through the arrangement of the material guiding mechanisms, and meanwhile the service life of the material guiding mechanisms is prolonged.

    本发明公开了一种用于大基坑的土方转运桥,包括对称设置的桥体,桥体包括对称设置的下梁架,下梁架上方安装若干三角钢架,三角钢架顶部固定连接上梁架,两个桥体的下梁架之间通过连接机构相连,两个桥体之间设有提升斗,提升斗两侧通过钢绳与提升机构相连,提升机构固定安装在上梁架靠近连接机构一端,下梁架和上梁架之间还对称固定安装立柱,立柱固定安装在下梁架和上梁架靠近靠近连接机构一端,立柱之间固定安装导料机构。本发明两个桥体之间的间距可调,方便在不同跨度基坑上架设,同时提升斗和提升机构的设置方便对两侧的支撑板进行倾倒,提高了土方转运的效率,另外导料机构的设置可以防止土方洒落,同时延长了导料机构的使用寿命。
