Large-tonnage bridge pushing deviation rectifying device
The invention relates to a large-tonnage bridge pushing deviation rectifying device which comprises a base, a counter-force bracket, a deviation rectifying jack, a displacement box and jacking jacks, a low-friction-resistance sliding plate is installed in a clamping groove of the base, the displacement box is placed on the low-friction-resistance sliding plate, the jacking jacks are placed in the displacement box, the displacement box is of a buckling cover type structure, and an upper cover is connected to the box body of the displacement box in a buckling and pressing mode; the counter-force bracket is arranged at one front end part of the base, the horizontal deviation rectifying jack is arranged between the counter-force bracket and the displacement box, and the counter-force bracket provides sufficient horizontal counter-force support for the horizontal deviation rectifying jack; displacement limiting screw rods and scales are arranged on the two sides and the rear end portion of the base, the displacement limiting screw rods can adjust the internal elongation amount through screwing, and the elongation amount is accurately controlled through the scales. The use method is simple, operation is convenient and fast, the device can be used for pushing and deviation rectifying construction of a large-tonnage bridge with the large weight, the limiting and locking functions are achieved, and a practical and feasible solution is provided for deviation rectifying construction after the bridge deviates.
本发明涉及一种大吨位桥梁顶推纠偏装置，包括基座、反力牛腿、纠偏千斤顶、位移箱、顶升千斤顶，基座的卡槽内安装低摩阻滑板，低摩阻滑板上放置位移箱，位移箱内放置多台顶升千斤顶，位移箱为扣盖式构造，位移箱的箱体上扣压连接上盖；基座的一前端部设置反力牛腿，反力牛腿与所述位移箱之间设置水平纠偏千斤顶，由所述反力牛腿为水平纠偏千斤提供充足的水平反力支撑；基座两侧及后端部设置位移限制螺杆及标尺，位移限制螺杆可通过旋拧调节内部伸长量，并通过标尺对伸长量进行精确控制。本发明使用方法简单、操作便捷，可用于重量较大的大吨位桥梁顶推纠偏施工，并具有限位锁定功能，为桥梁偏移后需要进行纠偏施工提供实际可行的解决方案。
