Referring to Fig. 1; The hydraulic schematic diagram of disjunctor compression box hydraulic system; Disjunctor compression box hydraulic system comprises fuel tank 17, motor 11, oil hydraulic pump 12, oil-feed path 9, way to cycle oil 10, shoveling oil cylinder 21, overturning oil cylinder 22, differential valve 1, shoveling valve 2, interlock valve 3, roll-over valve 4, and said motor 11 links to each other with oil hydraulic pump 12; One end of said oil hydraulic pump 12 links to each other with said fuel tank 17 through filter 16, and the other end links to each other with oil-feed path 9; Said overturning oil cylinder 22 and said roll-over valve 4 link to each other through pipeline; Said differential valve 1, shoveling valve 2, interlock valve 3, roll-over valve 4 are the two-position four way change valve that comprises A, B, P, four hydraulic fluid ports of T; Said oil-feed path 9 is connected with the P mouth of interlock valve 3; Said way to cycle oil 10 directly links to each other with the T mouth of differential valve 1 and the T mouth of shoveling valve 2 respectively; And said way to cycle oil 10 also links to each other with the T mouth of interlock valve 3 and the T mouth of roll-over valve 4, is provided with an one-way valve between the P mouth of said oil-feed path 9 and interlock valve 3, is provided with a plug-in type one-way valve 5 between the T mouth of said way to cycle oil 10 and said roll-over valve 4; The A mouth of said interlock valve 3 links to each other with the P mouth of roll-over valve 4, and the B mouth of said interlock valve 3 links to each other with the P mouth of shoveling valve 2; The A mouth of said differential valve 1 and the A mouth of shoveling valve 2 are connected in parallel, and its oil circuit is connected with the rodless cavity of said shoveling oil cylinder 21; The P mouth of said differential valve 1 is connected with the rod chamber of said shoveling oil cylinder 21, between the T of said shoveling valve 2 mouth and A mouth, is provided with a stacking type hydraulic control check valve 6.
In the utility model, the B mouth of said differential valve 1 and the B mouth of shoveling valve 2 are connected in parallel, and its oil circuit links to each other with the control end of said stacking type hydraulic control check valve 6; The A mouth of said roll-over valve 4 all links to each other with rod chamber with the rodless cavity of said overturning oil cylinder 22 respectively with one-way throttle valve 8 through one-way valve 7 with the B mouth.Said way to cycle oil 10 also links to each other with fuel tank 17 through the one-way valve as back pressure valve.
In the utility model; Between said oil-feed path 9 and the way to cycle oil 10, be equipped with a relief valve 19 between the A mouth of said way to cycle oil 10 and interlock valve 3; Said way to cycle oil 10 is connected with fuel tank 17 through the filter 13 of cooler 14 and band bypass valve; Said fuel tank 17 also is connected with a level meter 15, also is connected with pressure transducer 18 and pressure measuring tie-in 20 on the said oil-feed path 9.On the said fuel tank 17 the prepressing type air-strainer is installed, fluid spills fuel tank when preventing the fuel tank inclination.
Aviation socket, emergency stop switch, key operation, yellow button, the green button, rising button and decline button are installed on the utility model panel.During work, press the green button, motor start-up; The electromagnet DT1 of differential valve 1 gets electric, oil hydraulic pump 12 fuel-displaced through the P of interlock valve 3 mouth to the B mouth, the P mouth that gets into shoveling valve 2 is to the B mouth; Again through the B of differential valve 1 mouth to the T mouth, oil sump tank 17 (being No Load Start motor and oil pump).The DT1 0.5 second dead electricity of delaying time, the oil hydraulic pump 12 fuel-displaced B mouths that change by differential valve 1 flow to the P mouth, get into the rod chamber of shoveling oil cylinder 21 again, promote shoveling oil cylinder 21 rollbacks.Have part fluid directly to walk around shoveling valve 2 in this fall back process and cool back fuel tank 17 through filter through the Pilot operated check valve of opening 6, part through shoveling valve 2 after filter cools back fuel tank 17.Reduce back pressure and power loss, the fluid heating reduces.
After shoveling return back to end of travel, pressure rose, and pressure transducer detects pressure greater than 150bar (adjustable), and it is electric that program gets the DT1 of differential valve 1, promptly sheds rod chamber and pumping pressure, delayed time 0.3 second, and the DT1 dead electricity, DT2 gets electric shoveling to begin.(differential timing A (X) beginning), DT2 promptly detects pressure after getting electric 0.3 second, and during less than 160bar (adjustable), DT1 gets electric, pushes open the beginning soon.When shoveling pressure was raised to 160bar, DT2 dead electricity (this moment DT1 not dead electricity) shed pump pressure, the DT1 dead electricity after 0.2 second of delaying time, and DT2 gets electric, pushes the beginning (differential timing A (X) completion) slowly open; When pressure is raised to 190bar (adjustable), dead electricity after DT2 delayed time 2.3 seconds again, DT1 gets electric, sheds pump pressure and shoveling rodless cavity pressure.The DT1 that delays time after 0.3 second gets electric, shoveling rollback, (retreating timing B (X) beginning); When shoveling return back to the oil cylinder stroke terminal point, pressure is elevated to 150 bar (adjustable), (retreating timing B (X) accomplishes).DT1 gets electric, sheds pumping pressure and rod chamber pressure, and DT1 time-delay dead electricity after 0.3 second is return completion.
DT1 time-delay is dead electricity after 0.3 second, begins second compression cycle immediately, DT2 again electric, shoveling is released and is begun ... Timing A (X+1), B (X+1); A (X+2), B (X+2); A (X+3), B (X+3); If press the green button, if under empty van zero load or underloading situation, differential timing time is greater than 17 seconds, only carry out 3 compression cycle after, return to the end, motor 11 is shut down; If press the green button, if under heavily loaded situation, differential timing time is less than 17 seconds, only carry out 1 compression cycle after, return to the end, motor 11 is shut down.Keep more than 10 seconds if pin the green button, shoveling is unrestrictedly circulation under normal circumstances, stops up to human intervention.
In the automatic cycle process, press yellow button, withdraw from automatic cycle.If do not continue by yellow button, direct power failure motivation just, if continue to pin yellow button, shoveling crawl retraction then, hand is parked in a certain position once decontroling, the power failure motivation, if crawl yellow button once more, then shoveling continues to return to bottom (original position).If continue by yellow button in " original position ", then " other warnings " literal appears in man-machine interface.If once more by yellow button, attonity.Must restart power supply, could recover normal.
When shoveling moves automatically, press and rise and two buttons that descend, stop the shoveling action at once, corresponding execution lifting action.After crawl finished, shoveling was then carried out automatically.
Half aviation socket (female end) is installed on the panel of the utility model; And second half aviation socket (public end) offers the user and connects electrical source of power; Emergency stop switch (urgent time press shutdowns) also is installed, key operation (avoiding unrelated person arbitrarily to operate without authorization) on the panel.
More than show and described basic principle of the utility model and the advantage of major character and the utility model; The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
