Trolley hydraulic system of steel rail grinding wagon
The invention discloses a trolley hydraulic system of a steel rail grinding wagon, which relates to the technical field of grinding equipment and comprises a hydraulic power source, a trolley ascending/descending oil cylinder, a trolley hook retracting/releasing oil cylinder and a dust blocking mechanism retracting/releasing oil cylinder. The trolley hook retracting/releasing oil cylinder is controlled through the trolley hook retracting/releasing control valve set, the dust blocking mechanism retracting/releasing oil cylinder is controlled through the dust blocking mechanism retracting/releasing control valve set, and the hydraulic power source provides hydraulic oil for the trolley ascending/descending control proportional multi-way valve, the trolley hook retracting/releasing control valve set and the dust blocking mechanism retracting/releasing control valve set. A trolley pressurization constant-pressure control unit is arranged on the trolley ascending/descending oil cylinder; and the trolley pressurization constant-pressure control unit is further provided with a pressure maintaining and energy storage control unit. The functions of trolley lifting, putting down, pressurizing and the like in the grinding operation process of the grinding wagon can be guaranteed, and therefore the grinding function is achieved.
本发明公开了一种钢轨打磨车的小车液压系统，涉及打磨设备技术领域，包括液压动力源、小车升/降油缸、小车挂钩收/放油缸、挡尘机构收/放油缸，小车升/降油缸通过小车升/降控制比例多路阀进行控制，小车挂钩收/放油缸通过小车挂钩收/放控制阀组进行控制，挡尘机构收/放油缸通过挡尘机构收/放控制阀组进行控制，且液压动力源为小车升/降控制比例多路阀、小车挂钩收/放控制阀组、挡尘机构收/放控制阀组提供液压油；所述小车升/降油缸上配设有小车加压恒压控制单元，小车加压恒压控制单元还配设有保压蓄能控制单元。本发明能保证打磨车在打磨作业过程中小车提升、放下和加压等功能，从而实现打磨功能。
