Detailed description of the invention
As shown in Fig. 1, Fig. 3 and Fig. 4, the urgent return of a kind of slag ladle of the present invention and the hydraulic efficiency pressure system of unloading tank, between the rodless cavity 62 being connected to armful tank car big arm cylinder and rod chamber 61, comprise the first change-over valve 1 be connected with oil pump 9, first hydraulic fluid port a of the first change-over valve 1 is connected with the pilot control opening d of the second change-over valve 2, first hydraulic fluid port f of the second change-over valve 2 is connected with rodless cavity 62, and the second hydraulic fluid port e of the second change-over valve is connected with rod chamber 61.The present invention controls being communicated with of the second change-over valve first hydraulic fluid port f and the second hydraulic fluid port e by the first change-over valve 1, and then realize being communicated with of rodless cavity 62 and rod chamber 61, when embracing tank car and being out of order, still big arm cylinder can be made to work on, slag ladle is put back to safely on ground, car or complete and unload tank, improve the safety of slag ladle transport.
C1, V1 in Fig. 1 are the hydraulic fluid port that hydraulic efficiency pressure system of the present invention is connected with rod chamber, C2, V2 are the hydraulic fluid port that hydraulic efficiency pressure system of the present invention is connected with rodless cavity, Y, K are the hydraulic fluid port that hydraulic efficiency pressure system of the present invention is connected with oil pump, and T is the hydraulic fluid port that hydraulic efficiency pressure system of the present invention is connected with fuel tank.
First hydraulic fluid port a of above-mentioned first change-over valve 1 is also connected with the pilot control opening g of a balance cock 3, and a hydraulic fluid port of balance cock 3 is connected with described rodless cavity, and another hydraulic fluid port of balance cock is connected with fuel tank.First change-over valve 1 controls the keying of balance cock, and when the oil in rodless cavity can be made to enter rod chamber by the first change-over valve, a part is back to fuel tank, to avoid oil spilling.
Also comprise a Fill valve 4, the oil inlet of Fill valve 4 is connected with fuel tank, and the oil outlet of Fill valve is connected with rodless cavity 62.When the oil of rod chamber 61 flows to rodless cavity 62, for avoiding occurring vacuum state in rodless cavity, inject fluid by Fill valve in rodless cavity, the fluid accelerated in rod chamber flows in rodless cavity.
First change-over valve 1 is the priority valve of the second change-over valve 2, is pilot-controlled multi-way reversing valve, is at least hydraulic-control two-position three-way reversing valve.And the first change-over valve is connected with the 3rd change-over valve 10 in oil pump 9 by two other hydraulic fluid port b, c, which control by the 3rd change-over valve 10 hydraulic fluid port that first change-over valve 1 is connected with oil pump to be connected with the first hydraulic fluid port a, the second hydraulic fluid port b that first change-over valve is connected with oil pump is the pilot control opening of the first change-over valve, and the 3rd hydraulic fluid port c is return opening.3rd change-over valve can be two-position four way change valve.
Above-mentioned second change-over valve is at least hydraulic control bi-bit bi-pass change-over valve, can be other pilot-controlled multi-way reversing valve.
First change-over valve is adopted hydraulic-control two-position three-way reversing valve below, the second change-over valve is hydraulic control bi-bit bi-pass change-over valve further describes hydraulic efficiency pressure system of the present invention principle of work as preferred embodiment.
When vehicle breaks down, as driving engine, change speed gear box does not work or hydraulic system fault, embrace tank car cisco unity malfunction, and slag ladle is in airborne status, now, as shown in Figure 3, the second hydraulic fluid port b of the first change-over valve 1 in hydraulic efficiency pressure system of the present invention is passed to by process oil oil pump feed, now the lower end pilot control opening of the first change-over valve 1 communicates with the second hydraulic fluid port b, the upper end spring force of the first change-over valve is overcome in the effect of pressure, promote the spool upward movement of the first change-over valve, thus the second hydraulic fluid port b achieving the first change-over valve 1 communicates (see Fig. 1) with the first hydraulic fluid port a, then pressure oil branches to the pilot control opening d of the second change-over valve 2 and pilot control opening g of balance cock 3 by the first hydraulic fluid port a of the first change-over valve, second change-over valve 2 is under the effect of left side guide's oil pressure, overcome the effect of right-hand member spring force, promote its inner spool to move right, thus achieve being communicated with of big arm cylinder rodless cavity and rod chamber, large arm Bao Guan mechanism is under the Action of Gravity Field of slag ladle, being repositioned to safely and reliably by slag ladle on car puts on tank position or ground, also the slag ladle just in discharging can be completed and unload tank work.
Be in below in conjunction with big arm cylinder and extend or shrink the working process that two states introduce this hydraulic efficiency pressure system in detail.
As shown in Figure 2, in figure, solid line state is the state that slag ladle 7 takes in one's arms from ground by the large arm Bao Guan mechanism 8 of embracing tank car 5, and now big arm cylinder 6 is in the state of stretching out, and breaks down if this state embraces tank car, big arm cylinder work can not be made, now open hydraulic efficiency pressure system of the present invention.As shown in Figure 3, by oil pump 9 to hydraulic efficiency pressure system fuel feeding of the present invention, the rodless cavity 62 of big arm cylinder is communicated with rod chamber 61, fluid now in rod chamber flows in rodless cavity by the second change-over valve 2, additionally by Fill valve 4 from fuel tank to repairing in rodless cavity, thus ensures not form vacuum in rodless cavity, fluid in rod chamber flows into rodless cavity smoothly, big arm cylinder 6 will work on, and under the Action of Gravity Field of slag ladle, slag ladle is put back to ground safely by large arm Bao Guan mechanism 8.
As shown in Figure 2, in figure, dotted line is the state that slag ladle 7 takes in one's arms from car by the large arm Bao Guan mechanism 8 of embracing tank car 5, and now big arm cylinder 6 is in contraction state, breaks down if this state embraces tank car, big arm cylinder work can not be made, now open hydraulic efficiency pressure system of the present invention.As shown in Figure 4, by oil pump 9 to hydraulic efficiency pressure system fuel feeding of the present invention, the rodless cavity 62 of big arm cylinder is communicated with rod chamber 61, fluid now in rodless cavity flows in rod chamber by the second change-over valve 2, a fluid part in rodless cavity flows in rod chamber by the second change-over valve, another part fluid flows back to fuel tank by balance cock 3, fluid in rodless cavity flows into rod chamber, big arm cylinder will work on, and under the Action of Gravity Field of slag ladle, slag ladle is put back to safely on car by large arm Bao Guan mechanism 8.
After the system failure of vehicle is removed, the manual reverse of direction handle of the 3rd change-over valve 10 on operation oil pump 9, thus the second hydraulic fluid port b of the first change-over valve 1 in hydraulic efficiency pressure system of the present invention and fuel tank are disconnected, the lower end pilot control mouth pressure of the first change-over valve is zero, first change-over valve is under the effect of upper end spring force, and its spool moves downward; Thus the first hydraulic fluid port a achieving the first change-over valve communicates with the 3rd hydraulic fluid port c; Now the pressure oil of the second change-over valve pilot control opening d and the pressure oil of balance cock pilot control opening g all flow back to fuel tank by the first change-over valve 1, the pressure vanishing of pilot control opening, second change-over valve and balance cock get back to off-state under spring force, make the rodless cavity of armful tank car big arm cylinder and rod chamber become off-state by the connected state of hydraulic efficiency pressure system of the present invention, make to embrace a tank car with this and normally run.
