The specific embodiment
As shown in Figure 1-2, a kind of coordinated type ladle turret hydraulic drive mechanism described in the utility model embodiment, comprise checking cylinder 1, described checking cylinder 1 connects the working hole of solenoid directional control valve 3 by one way pressure-reducing valve 1, the oil-in Bonding pressure pipe of described solenoid directional control valve 3, together with the oil-in of the oil return opening of described solenoid directional control valve 3 and one way pressure-reducing valve 24, be connected to the oil-out of shuttle valve 5, described one way pressure-reducing valve 24 is connected with hydraulic clutch 6, the oil-in of described shuttle valve 5 is connected with respectively the working hole of hydraulic motor 7 and hand-operated direction valve 8, the oil-in Bonding pressure pipe of described hand-operated direction valve 8, the oil return opening of described hand-operated direction valve 8 connects oil return pipe.Described one way pressure-reducing valve 1, one way pressure-reducing valve 24 and hydraulic motor 7 are all connected with blow-by tube.The oil-in of described hand-operated direction valve 8 is connected with adjustable throttling 9.Described one way pressure-reducing valve 1, one way pressure-reducing valve 24 and adjustable throttling 9 are all connected with Pressure gauge 11 by pressure measuring tie-in 10; The entrance of hydraulic motor (7) is provided with pressure measuring tie-in 10.The entrance of described force pipe entrance, checking cylinder 1 entrance, hydraulic clutch 6 entrances and hydraulic motor 7 is equipped with stop valve 12.Described oil return pipe entrance is provided with check valve 13.
The coordinated type ladle turret hydraulic drive mechanism that the utility model provides, has been used the principle that shuttle valve 5 and one way pressure-reducing valve can reverse circulated.Under accident condition, when ladle turret rotates, drive the pressure oil of hydraulic clutch 6 and checking cylinder 1 to come from by shuttle valve 5 side that hydraulic motor 7 pressure are high; During ladle turret braking, hydraulic clutch 6 and checking cylinder 1 are by one way pressure-reducing valve, shuttle valve 5, hand-operated direction valve 8 oil returns; Thereby the interlock that has realized ladle turret is controlled.In the situation that assurance function is constant, the hydraulic circuit principle that ladle turret interlock is controlled is simplified, and has saved 1 solenoid directional control valve and 2 pilot operated directional control valves, with 1 shuttle valve, has replaced 4 check valves, has reduced element purchase cost; In hydraulic test, the design of oil path block is simplified, and the volume of oil path block reduces greatly, and difficulty of processing reduces, thereby has reduced production cost.
