The invention provides a hydraulic valve bank of a full-hydraulic steering gear, which belongs to the technical field of hydraulic valve banks and comprises a valve body, a valve sleeve and a valve core, four oil ports, namely an oil port T, an oil port P, an oil port A and an oil port EF, are formed in one side of the valve body, an oil port B is formed in the other side of the valve body, the oil port T and the oil port P are used for communicating with a hydraulic pump station, and the oil port A and the oil port B are used for communicating with a steering oil cylinder of an electric forklift. The EF oil port is used for being communicated with a multi-way valve of the inserting arm lifting oil cylinder, and then the steering oil cylinder of the electric forklift is controlled to provide the pressure of the remaining hydraulic oil for the inserting arm lifting oil cylinder when working. The hydraulic valve bank of the full-hydraulic steering gear has the technical effects that one power unit can be used for steering of an electric forklift and lifting operation of an insertion arm, hydraulic oil can be reutilized, and energy conservation and emission reduction are achieved.
本发明提供了一种全液压转向器液压阀组,属于液压阀组技术领域,包括阀体、阀套和阀芯,阀体一侧设置有四个油口,分别为T油口、P油口、A油口和EF油口,另一侧设置有B油口,T油口和P油口用于连通液压泵站,A油口和B油口用于连通电动叉车的转向油缸,EF油口用于连通插臂升降油缸的多路阀,进而控制电动叉车的转向油缸在工作时将剩余液压油的压力提供给插臂升降油缸。本发明提供的一种全液压转向器液压阀组,具有能使用一组动力单元,用于电动叉车的转向和插臂升降操作,液压油可二次利用,实现节能减排的技术效果。
