A kind of hydraulic dumping device, including hydraulic cylinder one and hydraulic cylinder two, described hydraulic cylinder one and hydraulic cylinder two are connected to control valve group one and control valve group two, wherein, being equipped with the valve that contends with in described control valve group one and control valve group two, the other end of described control valve group one and control valve group two is connected to Double throttle check valve jointly also by some pipelines, and described Double throttle check valve is connected to electro-hydraulic reversing valve, wherein, described pipeline is also equipped with ball valve and high-pressure rubber pipe.
Further, the release ball valve one and the release ball valve two that match it are also associated with between described hydraulic cylinder one with described hydraulic cylinder two.
Further, described release ball valve one is also connected with the drain tap of described electro-hydraulic reversing valve jointly with release ball valve two.
The beneficial effects of the utility model: by electro-hydraulic reversing valve, Double throttle check valve being arranged in control valve group, so can realize hydraulic cylinder commutation and speed-regulating function；The valve that will contend with is arranged on ram control valve block; and with electro-hydraulic reversing valve (y-function), Double throttle check valve (meter in control) with the use of; hydraulic cylinder can be made to be parked in optional position; the hypervelocity that can also prevent it in decline process owing to deadweight causes; also after can guarantee that pipe breakage, hydraulic cylinder can be locked in current location simultaneously, serves the function of overflow protection.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the hydraulic dumping device according to this utility model embodiment.
In figure:
1, hydraulic cylinder one；2, hydraulic cylinder two；3, valve group one is controlled；4, valve group two is controlled；5, contend with valve；6, Double throttle check valve；7, electro-hydraulic reversing valve；8, ball valve；9, high-pressure rubber pipe；10, release ball valve one；11, release ball valve two.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain, broadly fall into the scope of this utility model protection.
As shown in Figure 1, a kind of hydraulic dumping device according to this utility model embodiment, including hydraulic cylinder 1 and hydraulic cylinder 22, described hydraulic cylinder 1 and hydraulic cylinder 22 are connected to control valve group 1 and control valve group 24, wherein, described control valve group 1 and control valve group 24 are equipped with the valve 5 that contends with, the other end of described control valve group 1 and control valve group 24 is connected to Double throttle check valve 6 jointly also by some pipelines, described Double throttle check valve 6 is connected to electro-hydraulic reversing valve 7, wherein, described pipeline is also equipped with ball valve 8 and high-pressure rubber pipe 9.
In one embodiment, the release ball valve 1 and the release ball valve 2 11 that match it are also associated with between described hydraulic cylinder 1 with described hydraulic cylinder 22.
In one embodiment, described release ball valve 1 is also connected with the drain tap of described electro-hydraulic reversing valve 7 jointly with release ball valve 2 11.
Understand technique scheme of the present utility model in order to convenient, below by way of in specifically used mode, technique scheme of the present utility model is described in detail.
When specifically used, according to hydraulic dumping device described in the utility model, when ladle pot tilting device rises, electro-hydraulic reversing valve 7 is in right position, hydraulic medium enters hydraulic cylinder rodless cavity by electro-hydraulic reversing valve 7, Double throttle check valve 6, the valve 5 that contends with, and the hydraulic medium in hydraulic cylinder rod chamber returns to fuel tank by Double throttle check valve 6, electro-hydraulic reversing valve 7 simultaneously.Double throttle check valve 6 regulates the movement velocity of hydraulic cylinder.
When ladle pot tilting device stops, electro-hydraulic reversing valve 7 is in middle position, and the valve 5 that contends with cuts out, and makes ladle pot tilting device optional position lock.If load pressure exceedes the setting pressure of the valve 5 that contends with, the valve 5 that contends with is opened, it is to avoid hydraulic system is damaged due to superpressure.
When ladle pot tilting device declines, electro-hydraulic reversing valve 7 is in left position, hydraulic medium is directly entered the rod chamber of hydraulic cylinder by electro-hydraulic reversing valve 7, Double throttle check valve 6, hydraulic medium in hydraulic cylinder rodless cavity returns to fuel tank by the valve 5 that contends with, Double throttle check valve 6, electro-hydraulic reversing valve 7 simultaneously, because the valve 5 that contends with produces back pressure on oil return line, therefore it is prevented from oil cylinder in decline process owing to deadweight causes hypervelocity.
If broken at ladle pot tilting device decline process mesohigh sebific duct 9, the valve 5 that contends with cuts out, and hydraulic cylinder stops declining.After recovering high-pressure rubber pipe 9 connection, as long as the right position of electro-hydraulic reversing valve 7 obtains electric, system gets final product normal operation.
Release ball valve is for the manual release of hydraulic cylinder rod chamber.
In sum, by means of technique scheme of the present utility model, by electro-hydraulic reversing valve, Double throttle check valve being arranged in control valve group, hydraulic cylinder commutation and speed-regulating function so can be realized；The valve that will contend with is arranged on ram control valve block; and with electro-hydraulic reversing valve (y-function), Double throttle check valve (meter in control) with the use of; hydraulic cylinder can be made to be parked in optional position; the hypervelocity that can also prevent it in decline process owing to deadweight causes; also after can guarantee that pipe breakage, hydraulic cylinder can be locked in current location simultaneously, serves the function of overflow protection.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
