Working principle:
Solenoid directional control valve 37 1 end electromagnet are opened; Valve body P chamber is communicated with the valve A chamber; Oil supply system is to valve body P accent input hydraulic pressure oil; Hydraulic oil is divided into two-way (R chamber oil circuit and AB chamber oil circuit) after getting into the P accent, and R chamber oil circuit flows out via valve body R chamber port through INSERTTYPE one-way valve 46, and oil circuit gets into cylinder body R through the R chamber
AB chamber oil circuit hydraulic oil is divided into three oil circuits (A chamber oil circuit, B chamber oil circuit, control oil channel) through piloted reducer 42, INSERTTYPE one-way valve 47; Control oil channel is through INSERTTYPE one-way valve 44, solenoid directional control valve 37; The control chamber that gets into the control cover plate 39 of tape travel limiters and remote control port through shuttle valve 38 is again closed inner valve body, thus B chamber oil circuit close, make hydraulic oil flow out from the valve A chamber; Get into cylinder body A chamber 18 through A chamber transport pipe 7; Front end piston rod 3 is moved to right-hand member withstand on rear end piston rod 24 left ends, connect pressure gauge through cylinder body R chamber pressure measuring tie-in 32 simultaneously, adjustment valve body piloted reducer 42, INSERTTYPE relief valve 35 make cylinder body A cavity pressure reach 5Mpa; Because the working principle of INSERTTYPE one-way valve 44 and closing of B chamber oil circuit make cylinder body A chamber 18 be in packing state.
Two above-mentioned work have realized the return action of hydraulic jack.Return action makes the hydraulic oil in cylinder pressure body B chamber 19 flow out through cylinder body B chamber port 12, flows to the valve B chamber again, and the spool of the control cover plate 34 of process band operating position point monitoring flows out from valve body T chamber and flows back to fuel tank again.
The electromagnet of solenoid directional control valve 37 the other ends is opened; Solenoid directional control valve 37 makes valve body P chamber be communicated with the B chamber; Control oil channel closes spool through the control oil pocket that INSERTTYPE one-way valve 44, solenoid directional control valve 37 get into the control cover plate 34 of band operating position point monitoring, thereby makes oil circuit close.Simultaneously the control oil pocket of the control cover plate 39 of tape travel limiter and remote control port flows back to fuel tank through shuttle valve 38, solenoid directional control valve 37, INSERTTYPE one-way valve 44 from valve body L chamber, makes the spool of control cover plate 39 of tape travel limiter and remote control port open.The hydraulic oil of B chamber oil circuit is through spool port outflow from the valve B chamber of the control cover plate 39 of tape travel limiter and remote control port; Flow into cylinder body B chamber port 12 by the B accent again and get into cylinder body B chamber 19; This moment, A chamber oil circuit was communicated with differential connection of formation with B chamber oil circuit, made the 3 quick step-downs of front end piston rod, and the plunger type pressure relay 40 when pressure reaches 5MPa on the valve body sends signal; Fuel feeding system is closed, and overturning mechanism begins turning.The own wt of rolling object makes the cylinder body B chamber 19 that presses oil cylinder produce high pressure (about 29Mpa) through joint shaft bearing 2, rod end earrings 1, front end piston rod 3 in umklapp process; Because producing pushed at high pressure rear end piston 13, cylinder body B chamber 19 make cylinder body R chamber 20 produce high pressure simultaneously; Valve body INSERTTYPE relief valve 43 is opened; The pressure oil in cylinder body R chamber 20 flows out through INSERTTYPE relief valve 43; Through piloted reducer 42, INSERTTYPE one-way valve 47, valve B chamber, carry out repairing again through 34 couples of cylinder body B of control panel chamber 19 of band operating position point monitoring, the article that are reversed the object loading are emptied after; Send signal overturning mechanism through the limit switch on the control cover plate 34 of band operating position point monitoring again and set back, realized do action one time.
