Hydraulic control system on underwater hydraulic automatic grabbing beam
A hydraulic control system on an underwater hydraulic automatic grabbing beam comprises a hydraulic shaft penetrating device arranged on a grabbing beam body and a shaft penetrating signal hydraulic controller controlling the hydraulic shaft penetrating device. The hydraulic shaft penetrating device comprises pin shafts arranged in rodless cavities and iron bars arranged on the pin shafts. A pump is communicated with the interior of each rodless cavity through a loop of the hydraulic shaft penetrating device. The shaft penetrating signal hydraulic controller comprises a first oil cylinder and a first piston rod arranged in the first oil cylinder, a first oil tank is communicated with the first oil cylinder, and the first piston rod is connected with the iron bars. Multiple first liquid level sensors are arranged in the first oil tank and connected with the pumps. The hydraulic control system has the advantages that an electrical control system is replaced by the hydraulic system, and safety and stability of the control system are improved.
