The utility model discloses a cartridge valve hydraulic station for preventing blocking. The cartridge valve hydraulic station consists of a motor, an oil pump system, an energy accumulator, an oil inlet pipe, an oil outlet pipe, a pressure relief pipe and various valves, which are connected, wherein various valves comprise a proportional overflow valve, a direct-acting overflow valve, a brass ball valve, an electromagnetic directional valve, a check valve and a high-pressure globe stop valve. The cartridge valve hydraulic station is characterized in that the oil hole diameter of each valve is 9mm; the flow path of an oil way is as follows: pressure oil output by the oil pump system enters a high-pressure filter through a first check valve, is filtered by a filter and separated into three paths, wherein the first path enters the oil inlet pipe of a first brake system through a first electromagnetic valve, the second path enters the oil inlet pipe of a second brake system through a third electromagnetic valve,
