The invention provides a hydraulic control valve group and a hydraulic driving system, and relates to the technical field of hydraulics, the hydraulic control valve group comprises a prefill valve group, a parking electromagnetic valve, a parking pneumatic control reversing valve and a cable winding and unwinding reversing valve, the prefill valve group is connected with a hydraulic oil tank, and the cable winding and unwinding reversing valve is connected with the hydraulic oil tank; the liquid outlet end of the prefill valve set is used for being connected with a first braking energy accumulator, a second braking energy accumulator, a parking energy accumulator, the liquid inlet end of a parking electromagnetic valve and the liquid inlet end of a cable winding and unwinding reversing valve, the liquid outlet end of the parking electromagnetic valve is connected with the liquid inlet end of a parking pneumatic control reversing valve, and the liquid outlet end of the parking pneumatic control reversing valve is used for being connected with a parking brake. The liquid outlet end of the cable take-up and pay-off reversing valve is used for being connected with a cable take-up and pay-off motor. According to the hydraulic control valve bank, the arrangement space of the hydraulic control system and the complexity of pipeline arrangement in the hydraulic control system can be remarkably reduced, and maintenance personnel can conveniently overhaul the hydraulic control system.

    本发明提供了一种液压控制阀组及液压驱动系统,涉及液压技术领域,液压控制阀组包括充液阀组、驻车电磁阀、驻车气控换向阀及电缆收放换向阀,充液阀组与液压油箱连接,充液阀组的出液端用于分别与第一制动蓄能器、第二制动蓄能器、驻车蓄能器、驻车电磁阀的进液端及电缆收放换向阀的进液端连接,驻车电磁阀的出液端与驻车气控换向阀的进液端连接,驻车气控换向阀的出液端用于与驻车制动器连接,电缆收放换向阀的出液端用于与电缆收放马达连接。本发明的液压控制阀组可以显著减小液压控制系统的布置的空间和液压控制系统中管道布置的复杂度,方便维修人员对液压控制系统进行检修。
