The utility model provides a hydraulic device for replacing a wear plate of a bogie. The device comprises a vehicle body, a hydraulic station arranged on the vehicle body, a controller and a group ofhydraulic oil cylinders, wherein the hydraulic oil cylinders are detachably connected with a hydraulic station through hydraulic pipes, each hydraulic oil cylinder comprises a piston rod used for achieving ejection, when a wear-resisting sheet of the bogie is replaced, the piston rods of the hydraulic oil cylinders make contact with the bottom face of the bogie, and the heights of the piston rodsare adjustable. The problems that in the prior art, operation is complex, replacement efficiency is low, and jacking synchronism is difficult to guarantee when a bogie wear-resisting sheet is replacedare solved. 本实用新型提出一种转向架耐磨片更换用液压装置，包括有车体、设置在车体上的液压站、控制器和一组液压油缸，所述一组液压油缸通过液压管与液压站可拆卸式连接，所述液压油缸包括有用于实现顶出的活塞杆，转向架更换耐磨片时，所述一组液压油缸的活塞杆均与所述转向架底面接触，所述活塞杆为高度可调节的。通过本实用新型解决了现有技术中的转向架耐磨片更换存在的操作复杂、更换效率低、顶升同步性难以保证的问题。
