Prestress continuous beam pushing device
The invention belongs to the technical field of bridge construction, and particularly relates to a prestressed continuous beam pushing device which comprises a supporting block, a first jack is arranged at the lower end of the supporting block, a concentric-square-shaped block is fixedly connected to the upper end of the supporting block, a rectangular plate is fixedly connected to one side of the upper end of the concentric-square-shaped block, and a first rectangular sliding block is slidably connected to the upper end of the supporting block. Second jacks are fixedly connected to the two sides of the middle of the rectangular plate correspondingly, the output ends of the second jacks are fixedly connected with a first rectangular sliding block, a plurality of arc-shaped protruding strips are arranged at the lower end of the first rectangular sliding block, and oil leakage assemblies are arranged on the two sides of the lower end of the first rectangular sliding block correspondingly. The oil leakage assembly comprises third rectangular grooves formed between every two adjacent arc-shaped protruding strips, fourth rectangular grooves are formed in the upper ends of the multiple third rectangular grooves, the multiple arc-shaped protruding strips are arranged at the lower end of the first rectangular sliding block, the arc surface makes contact with the supporting block, and the contact area is reduced; the problem that the friction force between the first rectangular sliding block and the supporting block is large when the continuous beam is pushed is solved.
本发明属于桥梁施工技术领域，具体的说是一种预应力连续梁顶推装置，包括支撑块，所述支撑块下端设有第一千斤顶，所述支撑块上端固接有回形块，所述回形块上端一侧固接有矩形板，所述支撑块上端滑动连接有第一矩形滑块，所述矩形板中部两侧分别固接有第二千斤顶，所述第二千斤顶输出端与第一矩形滑块固接，所述第一矩形滑块下端设有若干弧形凸条，所述第一矩形滑块下端两侧分别设有漏油组件，所述漏油组件包括相邻两个弧形凸条之间均设有的第三矩形槽，若干所述第三矩形槽上端设有第四矩形槽，通过在第一矩形滑块下端设有若干弧形凸条，弧面与支撑块接触减少接触面积，解决了在对连续梁进行推动时第一矩形滑块与支撑块之间的摩擦力较大的问题。
