Intelligent walking type pushing system
The invention discloses an intelligent walking-type pushing system, and particularly relates to the technical field of bridge construction, an intelligent cluster controller is established to control all walking-type pushing equipment in a construction site, the intelligent walking-type pushing system is constructed, the intelligent cluster controller performs calculation according to real-time data of the pushing equipment in a cluster, and the real-time data of the pushing equipment in the cluster are calculated according to the real-time data of the pushing equipment in the cluster. A displacement and pressure signal instruction is sent to a single walking type pushing equipment controller to form an outer layer closed loop; the single walking type pushing equipment controller receives displacement and pressure signals of the pushing hydraulic system and outputs pressure and displacement signals to the two servo motor controllers respectively to form a displacement and pressure middle-layer closed loop; the servo motor controller converts the pressure and displacement signals into servo motor rotating speed signals to drive the servo motor to rotate as required, and meanwhile, a speed inner layer closed loop of the servo motor is formed through an encoder; through outer, middle and inner layers of closed loops, jacking and pushing synchronism and an automatic dynamic deviation correction function are accurately guaranteed.
本发明公开了智能步履式顶推系统，具体涉及桥梁施工技术领域，本发明建立智能集群控制器对施工场地所有的步履式顶推装备进行控制，构建智能步履式顶推系统，智能集群控制器根据集群内各顶推装备实时数据进行计算，对单台步履式顶推装备控制器发出位移和压力信号指令，构成外层闭环；单台步履式顶推装备控制器接收顶推液压系统位移和压力信号，并分别向两台伺服电机控制器输出压力和位移信号，构成位移和压力中层闭环；伺服电机控制器将压力和位移信号转换为伺服电机转速信号，驱动伺服电机按需转动，同时通过编码器，构成伺服电机的速度内层闭环；经过外、中、内三层闭环，精确保证顶升和顶推同步性及自动动态纠偏功能。
