AI Technical Summary

Technical Problem

The existing curved hatch opening and closing process is labor-intensive, inefficient, and has a low degree of automation. Manually pushing the latch and using the motor drive are cumbersome.

Method used

The system employs a hydraulic control system, including a power unit, a first load control unit, and a second load control unit. It achieves automated opening and closing of the arc-shaped hatch through components such as proportional directional valves and hydraulic cylinders, and uses hydraulic drive motors and hydraulic cylinders to drive the hatch to rotate and move.

Benefits of technology

The automated opening and closing of the arc-shaped hatch has been achieved, which greatly improves the opening and closing efficiency, reduces manual operation, and simplifies the opening and closing process.

Abstract

The hydraulic control system of the arc-shaped cabin door provided by the present disclosure belongs to the field of hydraulic control. The hydraulic control system comprises a power unit, a first load control unit and a second load control unit. The power unit comprises an oil tank and a variable drive pump, and the oil suction port of the variable drive pump is in communication with the oil tank. The first load control unit comprises a first proportional directional valve and a first oil cylinder, the oil inlet of the first proportional directional valve is in communication with the oil outlet of the variable drive pump, and the oil return port of the first proportional directional valve is in communication with the oil tank. The second load control unit comprises a second proportional directional valve and a motor, the oil inlet of the second proportional directional valve is in communication with the oil outlet of the variable drive pump, and the oil return port of the second proportional directional valve is in communication with the oil tank. The present disclosure can improve the opening and closing efficiency of the arc-shaped cabin door through the hydraulic control system.
