Abstract
The utility model provides a double-powering hydraulic jack, which comprises a bottom base. The bottom base is fixed with a main oil cylinder and an auxiliary oil cylinder. The auxiliary oil cylinder adopts two layers of cavity bodies. The upper end of an inner cavity is provided with a through hole. The space between the inner cavity body and an outer cavity body forms an annular oil storage cavity respectively connected with oil tank and the plunger cavity of the main oil cylinder by an oil path. The oil path opening connected with the oil tank of the main oil cylinder is provided with a non-return valve used for absorbing the oil. The bottom part of the plunger cavity of the auxiliary oil cylinder is also respectively connected with the oil tank and the plunger cavity of the main oil cylinder by the oil path. The oil path opening connected with the oil tank of the main oil cylinder is provided with one non-return valve used for absorbing the oil. The two oil path inlets of the plunger cavity of the main oil cylinder are respectively provided with a non-return valve used for lifting. The utility model is a new jack with scientific and reasonable structure, high work efficiency, time saving and labor saving. The utility model is suitable for being widely popularized and used.
Description
The utility model relates to a kind of jack, particularly a kind of hydraulic jack that can two-way work done.
At present, generally sell on the market and the jack that uses mostly is and prolongs the common unidirectional hydraulic jack of attacking for many years, its sealing adopts disposable sealings, in case can not adjust once more after reinforcing.This jack is because only can unidirectional work done, so the Use Limitation rate is low, the time-consuming merit of taking.
The purpose of this utility model provides a kind of scientific and reasonable for structure, high efficiency, time saving and energy saving novel double cropping merit hydraulic jack.
The purpose of this utility model is achieved in that it comprises base, be fixed with the master on the base, auxilliary two oil cylinders, it is characterized in that: auxilliary oil cylinder adopts double-layer cavity, and the upper end of inner chamber is provided with through hole, in, form annular shoe cream room between the outer chamber, the annular shoe cream room links to each other with plunger cavity with the oil sump of master cylinder by oil duct respectively, its oil duct junction place that links to each other with the master cylinder oil sump is provided with the oil suction boiler check valve, auxilliary oil cylinder plunger cavity bottom also links to each other with plunger cavity with the oil sump of master cylinder respectively by oil duct, its oil duct junction place that links to each other with the master cylinder oil sump is provided with the oil suction boiler check valve, and master cylinder plunger cavity two oil duct entrance are respectively equipped with the boiler check valve that hoists.
When using the utility model, lift or press down the plunger piston of auxilliary oil cylinder on no matter being, fluid all can enter in the cavity of resorption of master cylinder plunger, thereby make main oil cylinder piston remain upward movement, therefore it can make full use of and lift and press down two processes and realize two-way work done, thereby can improve the work efficiency of jack greatly, time saving and energy saving.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the utility model comprises base 17, be fixed with the master on the base 17, auxilliary two oil cylinders 1,7, auxilliary oil cylinder 7 adopts double-layer cavity, and the upper end of inner chamber 6 is provided with through hole, in making, exocoel 6, form annular shoe cream room 8 between 4 bodies, annular shoe cream room 8 is respectively by oil duct 10,14 link to each other with plunger cavity 20 with the oil sump 3 of master cylinder 1, its 10 mouthfuls of places of oil duct that link to each other with master cylinder 1 oil sump 10 are provided with oil suction boiler check valve 9, auxilliary oil cylinder 6 plunger cavities bottom is also by oil duct 12,13 link to each other with plunger cavity 20 with the oil sump 10 of master cylinder 1 respectively, it is provided with oil suction boiler check valve 11 with oil duct 13 entrance that master cylinder 1 oil sump 10 links to each other, and 20 liang of oil duct entrance of master cylinder 1 plunger cavity are respectively equipped with the boiler check valve 15 that hoists, 16.In order to realize resetting fast of jack, master cylinder 1 plunger cavity, 20 bottoms and oil sump 10 bottoms also are provided with oil drain hole 19 and are connected 18 with the oil cock that is rotated with on base 17.Working process of the present utility model is achieved in that when assisting the piston 5 of oil cylinder 7 plungers with subordinate pressure, by oil duct 14 and oil suction boiler check valve 9 oil is sucked auxilliary oil cylinder 7 plunger epicoeles from oil sump 10, make its piston 2 upward movements thereby the oil of plunger cavity of resorption enters master cylinder 1 plunger cavity 20 by the oil duct 13 and the boiler check valve 16 that hoists; When on when lifting auxilliary oil cylinder 7 pistons 5, by oil duct 12 and oil suction boiler check valve 9 oil is sucked auxilliary oil cylinder 7 plunger cavity of resorptions from oil sump 10, the oil of plunger epicoele enters master cylinder 1 plunger cavity of resorption by the oil duct 14 and the boiler check valve 15 that hoists, thereby make its piston 2 continue upward movement, going round and beginning again gets final product two-way work done, finally realizes efficient, time saving and energy saving purpose.
