Steel box girder pushing structure for bridge construction

LIU BINGSHU

The invention discloses a steel box girder pushing structure for bridge construction, and particularly relates to the field of steel box girder pushing equipment.The steel box girder pushing structure comprises a pushing structure body, the pushing structure body is fixedly connected with a containing plate used for installing other parts, and the side wall of the containing plate is connected with two adjusting mechanisms used for adjusting the size; the two adjusting mechanisms are each connected with an inserting mechanism used for inserting other parts, the two inserting mechanisms are each connected with a pushing mechanism used for making contact with a bridge column, and the two pushing mechanisms are each connected with a contact mechanism matched with the two inserting mechanisms. Two fixing mechanisms used for fixed parts are connected to the containing plate, the protection plate can improve the stability of one side of the pushing structure, so that the situation that the pushing structure is inclined due to uneven stress is avoided, the pushing structure can be further more stable, and therefore the pushing structure can be normally used.

本发明公开了一种用于桥梁施工的钢箱梁顶推结构，具体涉及钢箱梁顶推设备领域，包括顶推结构，所述顶推结构上固定连接有用于安装其他零部件的放置板，所述放置板的侧壁上连接有两个用于调节尺寸的调节机构，两个所述调节机构上均连接有用于插设其他零部件的插设机构，两个所述插设机构上均连接有用于接触桥梁柱的推动机构，两个所述推动机构上均连接有分别与两个插设机构相匹配的接触机构，所述放置板上连接有两个用于固定零部件的固定机构，本发明中防护板能够提高顶推结构一侧的稳定性，从而避免了顶推结构受力不均匀而导致倾斜的情况发生，进一步的能够使顶推结构更为稳定，从而能够使顶推结构正常使用。
