(3) latch oil hydraulic cylinder 7 piston rods withdrawals (descending)
When rotatable platform 1 turns an angle down in fork 3 effect, backstop iron stopped when slide block 6 arrived desired locations, the piston stop motion of active oil hydraulic cylinder 5; Initiatively the right chamber oil pressure of oil hydraulic cylinder 5 is elevated to the set pressure of pressure relay 19 immediately, and then pressure relay 19 signals and makes the 3YA dead electricity of solenoid directional control valve 13, then solenoid directional control valve 13 reset (meta); The 2YA of solenoid directional control valve 12 gets electric, and position, solenoid directional control valve 12 left side is inserted, and hydraulic oil gets into latch oil hydraulic cylinder 7 epicoeles through one-way throttle valve 14; Piston rod is withdrawn and is pulled pin, and after the action of pulling pin was accomplished, fork 3 lost with rotatable platform 1 and is connected; The hydraulic oil of latch oil hydraulic cylinder 7 cavity of resorptions is through Pilot operated check valve 16 and solenoid directional control valve 12 oil sump tanks 9; Because the existence of Pilot operated check valve 16 has constituted the locking loop, the action of pulling pin must could realize having bigger reliability in the epicoele oil-feed.
In-line: oil hydraulic pump 10 → reduction valve 11 → solenoid directional control valve 12 (position, a left side) → one-way throttle valve 14 → latch oil hydraulic cylinder 7 epicoeles.
Oil circuit: latch oil hydraulic cylinder 7 cavity of resorptions → Pilot operated check valve 16 → solenoid directional control valve 12 (position, a left side) → fuel tank 9.
(4) initiatively oil hydraulic cylinder 5 piston rods withdrawals (right lateral)
When position limit switch SA is met in the piston rod withdrawal of latch oil hydraulic cylinder 7; SA signals and makes the 2YA dead electricity of solenoid directional control valve 12, and solenoid directional control valve 12 resets (meta), and the 4YA of solenoid directional control valve 13 gets; Solenoid directional control valve 13 right positions are inserted; Hydraulic oil gets into the initiatively left chamber of oil hydraulic cylinder 5 through solenoid directional control valve 13 right positions, and the piston rod withdrawal is got back to initial position thereby drive slide block 6, connecting rod 4 and fork 3; And rotatable platform 1 is connected the position that rests on after the rotation and keeps state of rest because of losing with fork 3, and initiatively oil hydraulic cylinder 5 right chambeies are through one-way throttle valve 15 and solenoid directional control valve 13 right side oil sump tank 9.
In-line: oil hydraulic pump 10 → solenoid directional control valve 13 (right position) → initiatively oil hydraulic cylinder 5 left chambeies.
