The invention relates to a hydraulic stopper rod control system. The hydraulic stopper rod control system is characterized by comprising a support, an oil cylinder device provided with a displacement sensor, and a hydraulic control unit, wherein the oil cylinder device provided with the displacement sensor is connected with a stopper rod through the support, an upper oil port of the oil cylinder device passes a first rubber hose and a second high-pressure ball valve sequentially, a lower oil port of the oil cylinder device is sequentially connected with the hydraulic control unit through a second rubber hose and a third high-pressure ball valve, the hydraulic control unit is respectively connected with a main pressure pipeline and a main oil return pipeline through a fourth high-pressure ball valve and a second one-way valve, and the upper oil port and lower oil port of the oil cylinder device are connected through a first high-pressure ball valve. The hydraulic stopper rod control system is simple in structure and small in occupied space. The hydraulic stopper rod control system has the advantages that replacement is simplified, use is facilitated, the stopper rod can be closed automatically and quickly in emergency conditions, and safety production accidents cannot be caused. A stopper rod device has the advantages of accurate movement, convenience in control and maintenance, high use reliability, outstanding system safety and the like.
Description
technical field [0001] The invention relates to a stopper rod hydraulic control system. Background technique [0002] At present, the stopper rod control device of the tundish car of the continuous casting machine at home and abroad is driven by a high-precision servo motor driving a ball screw push rod. Due to the complex structure of the drive device composed of the servo motor and the ball screw, it takes up a lot of space and is difficult to replace, and the stopper cannot be automatically closed in an accident state, which easily leads to major safety production accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stopper rod hydraulic control system to overcome the defects in the prior art. [0004] Technical scheme of the present invention is: [0005] A stopper rod hydraulic control system, characterized in that: [0006] It includes a bracket, an oil cylinder device provided with a displacemen...
