Lateral limiting device for pushing prestressed continuous beam
The invention belongs to the technical field of lateral limiting of prestressed continuous beams, and particularly relates to a lateral limiting device for pushing a prestressed continuous beam which comprises a pier body, a continuous beam body erected on the pier body and a plurality of pushing devices arranged on the pier body. Each pushing device comprises a first hydraulic cylinder rotationally arranged on one side of the pier body; the output end of the second hydraulic cylinder is fixedly connected with a top frame; the pushing device further comprises a lateral limiting device arranged on one side of the second hydraulic cylinder, the lateral limiting device comprises a fixing frame rotationally arranged on one side of the top frame, and a limiting plate is arranged in the fixing frame. The two transverse plates are fixedly connected to one side of the top frame, the ends, away from the transverse plates, of the gears are meshed with first rack plates, and second rack plates are arranged between the two transverse plates in a sliding mode, by arranging the lateral limiting devices, the problem that before a continuous beam body is jacked up by a second hydraulic cylinder, slight deviation possibly occurs is solved, and therefore the deviation distance of the continuous beam is increased, and the stability of the continuous beam body is improved. And the subsequent butt joint of the continuous beam body is influenced.
本发明属于预应力连续梁侧向限位技术领域，具体的说是一种用于预应力连续梁顶推的侧向限位装置，该预应力连续梁包括墩体，搭设在墩体上的连续梁体，以及设置在墩体上的若干个顶推装置，每个顶推装置均包括转动设置在墩体一侧的第一液压缸；第二液压缸的输出端固接有顶框；顶推装置还包括设置在第二液压缸一侧的侧向限位装置，侧向限位装置包括转动设置在顶框一侧的固定框，固定框内设置有限位板；以及固接在顶框一侧的两个横板，齿轮远离横板的一端啮合有第一齿条板，两个横板之间滑动有第二齿条板，通过设置侧向限位装置，解决了连续梁体在被第二液压缸顶起之前，可能已经发生轻微偏移的情况，从而使连续梁偏移的距离增大，影响连续梁体后续对接的问题。
