Grinding system carried on steel rail grinding wagon
The invention discloses a grinding system carried on a steel rail grinding wagon, which relates to the technical field of grinding equipment and comprises a hydraulic power source, a grinding angle adjusting oil cylinder, a grinding stone ascending/descending oil cylinder, a grinding beam rotating oil cylinder, a grinding beam bolt locking/releasing oil cylinder and a grinding stone buckle locking/releasing oil cylinder. The grinding angle adjusting oil cylinder is controlled through a grinding angle adjusting control valve set, the grinding stone ascending/descending oil cylinder is controlled through a grinding stone ascending/descending control proportional multi-way valve, and the grinding beam rotating oil cylinder is controlled through a grinding beam rotating control proportional multi-way valve. The polishing beam bolt locking/releasing oil cylinder is controlled through a polishing beam bolt locking/releasing control valve group, and the millstone buckle locking/releasing oil cylinder is controlled through a millstone buckle locking/releasing control valve group; the hydraulic power source provides hydraulic oil for the grinding angle adjusting control valve set, the grinding stone ascending/descending control proportional multi-way valve, the grinding beam rotation control proportional multi-way valve, the grinding beam bolt locking/releasing control valve set and the grinding stone buckle locking/releasing control valve set. And the millstone ascending/descending oil cylinder is also provided with a millstone pressurizing and constant-pressure control unit. It can be guaranteed that in the grinding operation process of the grinding wagon, the grinding angle of the grinding mechanism is adjusted; lifting, putting down and pressurizing the millstone; rotating the polishing beam; locking and unlocking a polishing beam bolt; and the grinding stone buckle has unlocking and locking functions, so that the grinding function is realized.
本发明公开了一种搭载在钢轨打磨车上的打磨系统，涉及打磨设备技术领域，液压动力源、打磨角度调节油缸、磨石升/降油缸、打磨梁旋转油缸、打磨梁插销锁止/解除油缸、磨石扣锁止/解除油缸，且打磨角度调节油缸通过打磨角度调节控制阀组进行控制，磨石升/降油缸通过磨石升/降控制比例多路阀进行控制，打磨梁旋转油缸通过打磨梁旋转控制比例多路阀进行控制，打磨梁插销锁止/解除油缸通过打磨梁插销锁止/解除控制阀组进行控制，磨石扣锁止/解除油缸通过磨石扣锁止/解除控制阀组进行控制；所述液压动力源分别为打磨角度调节控制阀组、磨石升/降控制比例多路阀、打磨梁旋转控制比例多路阀、打磨梁插销锁止/解除控制阀组、磨石扣锁止/解除控制阀组提供液压油；所述磨石升/降油缸上还配设有磨石加压恒压控制单元。本发明能保证打磨车在打磨作业过程中打磨机构实现打磨角度调整；磨石提升、放下和加压；打磨梁旋转；打磨梁插销锁止和解除；磨石扣解锁和锁止功能，从而实现打磨功能。
