Graded pushing trolley system for bridge continuous pushing operation and construction method
The invention discloses a graded pushing trolley system for bridge continuous pushing operation and a construction method. The system comprises a hydraulic pushing sliding device, a sliding way, an automatic control system, a positioning device and a stress monitoring device; wherein the front hydraulic heavy-load jack and the rear hydraulic heavy-load jack jack at the same time and lift a bridge body, the rear hydraulic rail clamping device is clamped, the front hydraulic rail clamping device is loosened, and the rear hydraulic jack is controlled to conduct forward jacking operation; after the rear hydraulic jack is pushed to the preset length, the rear hydraulic rail clamping device is loosened, the rear hydraulic jack is retracted, meanwhile, the front hydraulic rail clamping device is tightened, and the front hydraulic jack is controlled to conduct forward pushing operation; the automatic navigation control system assists pushing through a positioning device and a stress monitoring device; and the front pushing device and the rear pushing device circularly work to realize continuous pushing. The system and method has the advantages of being high in pushing speed, high in continuous operation capacity, capable of dynamically adjusting the pushing direction, capable of preventing rail jamming caused by curve pushing and the like.
本发明公开一种桥梁连续顶推作业的分级顶推台车系统及施工方法，该系统包括液压顶推滑移装置、滑道、自动化控制系统、定位装置、应力监控装置；通过前液压重载千斤顶、后液压重载千斤顶同时顶升将桥梁梁体抬起，夹紧后液压夹轨器、同时松前液压夹轨器，控制后液压千斤顶向前顶推作业；后液压千斤顶顶推至预定长度后，松后液压夹轨器、收后液压千斤顶、同时加紧前液压夹轨器，控制前液压千斤顶向前顶推作业；自动化导航控制系统通过定位装置与应力监控装置辅助顶推；前顶推装置与后顶推装置循环作业，实现连续顶推；该发明具有顶推速度快、连续作业能力强、可动态调整顶推方位、防曲线顶推卡轨等优势。
