Description
Technical field
The utility model relates to a kind of ladle lifting hydraulic cylinder hydraulic control device.
Background technique
Ladle turret is constituent element important in casting machine, be usually arranged on converter bay and continuous casting across between.In order to realize protective casting, between ladle and tundish, submersed nozzle being installed, requiring that ladle can move up and down on traverse platform; Due to the restriction of continuous casting workshop layout, ladle is also often needed to move up and down.Because hydraulics has: specific power is high, flexible configuration, prevent the advantages such as overload, it is ladle elevating control mode conventional at present.
In order to ensure security of system, current conventional ladle lifting hydraulic control system all by locking position and speed-regulating function integrated installation on ladle lifting hydraulic cylinder, and and oil hydraulic cylinder be arranged on together near equipment.The drawback of this design is: steel ladle lifting speed must adjust near ladle, cannot realize speed adjustment in process of production; And after pipe breakage, ladle also can decline with the speed of setting, can't stop completely.
Model utility content
The utility model embodiment provides a kind of ladle lifting hydraulic cylinder hydraulic control device, to overcome prior art above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of ladle lifting hydraulic cylinder hydraulic control device, comprise the ladle lifting hydraulic cylinder, two-way plug-in valve, high-pressure rubber pipe and the electro-hydraulic reversing valve that are connected successively, described electro-hydraulic reversing valve is arranged on control valve platform, the oil supply loop of described ladle lifting hydraulic cylinder is provided with relief valve, and described relief valve, two-way plug-in valve, safety overflow valve and release ball valve form ram control valve group; The valve block of described ladle lifting hydraulic cylinder is provided with safety overflow valve and release ball valve; Described control valve platform is provided with series flow control valve.
Further, described series flow control valve is located between electro-hydraulic reversing valve and high-pressure rubber pipe.
Further, described ram control valve group is connected with the drain tap (L end) of electro-hydraulic reversing valve.
The beneficial effects of the utility model: in ladle decline process, when by relief valve flow exceed setting flow time, relief valve close, ladle stop decline; Described series flow control valve is installed on control valve platform, then can away from the speed that the control valve platform of ladle regulates ladle to be elevated; When induced pressure exceedes the setting pressure of safety overflow valve, safety overflow valve is opened, and avoids hydraulic system to damage due to superpressure; Release ball valve is used for manual release to be made ladle decline to avoid ladle to meet accident accident.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment 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 prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the ladle lifting hydraulic cylinder hydraulic control device according to the utility model embodiment.
In figure:
1, ladle lifting hydraulic cylinder; 2, two-way plug-in valve; 3, high-pressure rubber pipe; 4, electro-hydraulic reversing valve; 5, control valve platform; 6, relief valve; 7, safety overflow valve; 8, release ball valve; 9, series flow control valve; 10, ram control valve group.
Embodiment
Below in conjunction with the accompanying drawing 1 in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, belongs to the scope of the utility model protection.
According to embodiment of the present utility model, as shown in Figure 1, provide a kind of ladle lifting hydraulic cylinder hydraulic control device, comprise the ladle lifting hydraulic cylinder 1, two-way plug-in valve 2, high-pressure rubber pipe 3 and the electro-hydraulic reversing valve 4 that are connected successively, described electro-hydraulic reversing valve 4 is arranged on control valve platform 5, and the oil supply loop of described ladle lifting hydraulic cylinder 1 is provided with relief valve 6; The valve block of described ladle lifting hydraulic cylinder 1 is provided with safety overflow valve 7 and release ball valve 8; Described control valve platform 5 is provided with series flow control valve 9.Described series flow control valve 9 is located between electro-hydraulic reversing valve 4 and high-pressure rubber pipe 3.Described relief valve 6, two-way plug-in valve 2, safety overflow valve 7 and release ball valve 8 form ram control valve group 10.Described ram control valve group 10 is connected with the drain tap (L end) of electro-hydraulic reversing valve 4.
Described in the utility model embodiment, the working principle of ladle lifting hydraulic cylinder hydraulic control device is as follows:
When ladle rises, electro-hydraulic reversing valve 4 is in right position, two-way plug-in valve 2 pilot valve is in right position, hydraulic medium enters ladle lifting hydraulic cylinder 1 by electro-hydraulic reversing valve 4, series flow control valve 9, two-way plug-in valve 2 and relief valve 6, and series flow control valve 9 regulates the speed of ladle lifting hydraulic cylinder 1.
When ladle stops, electro-hydraulic reversing valve 4 is in left position, two-way plug-in valve 2 pilot valve is in right position, and two-way plug-in valve 2 is closed, and makes ladle locking position.
When ladle declines, electro-hydraulic reversing valve 4 is in left position, two-way plug-in valve 2 pilot valve is in left position, two-way plug-in valve 2 is oppositely opened, and hydraulic medium takes back oil by relief valve 6, two-way plug-in valve 2, series flow control valve 9 and electro-hydraulic reversing valve 4, and series flow control valve 9 regulates the speed of ladle lifting hydraulic cylinder 1.
If broken at the reverse opening process mesohigh sebific duct 3 of two-way plug-in valve 2, then increased by the flow of relief valve 6, once flow exceed the setting flow of relief valve 6, relief valve 6 cuts out, and ladle lifting hydraulic cylinder 1 stops declining.After recovering high-pressure rubber pipe 3 connection, as long as the right position of electro-hydraulic reversing valve 4 obtains electric, the A mouth pressure of relief valve 6 is raised, and relief valve 6 resets, and system can normally work.
If induced pressure exceedes the setting pressure of safety overflow valve 7, safety overflow valve 7 is opened, and avoids hydraulic system to damage due to superpressure.Release ball valve 8 makes ladle decline for manual release.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
