PURPOSE: A hydraulic connecting device for a ladle sliding gate is provided to eliminate residual pressure by discharging oil existed between a gate hydraulic cylinder and a main valve using a sub-valve. CONSTITUTION: A hydraulic connecting device for a ladle sliding gate is composed of a turret side hydraulic connecting unit(100) and a ladle side hydraulic connecting unit(200). The turret side hydraulic connecting unit comprises a coupling socket for connecting a pipe and a coupling hydraulic cylinder. The coupling socket has a locking member. The coupling hydraulic cylinder ascends and descends the locking member. The ladle side hydraulic connecting unit comprises a ladle side hydraulic pipe and a coupling plug for connecting the pipe. The coupling plug is automatically inserted into the coupling socket when a ladle(20) is installed in a ladle turret(10). |
