Description
Technical field
The utility model relates to jack field, is specifically related to a kind of hydraulic jack.
Background technology
Traditional mechanical jack, in order to workpiece being lifted to the height required by, just need by motion jack lever or lever handle have come repeatedly, after workpiece has unloaded, for recovering original state, still need by motion jack lever or lever handle repeatedly, the work intensity of operative employee is large, inefficiency, and the requirement on traditional jack pair ground is also very high, the smooth degree on such as ground, degree of dip of bearing surface etc., which also limits the range of use of jack.
Summary of the invention
The utility model provides a kind of hydraulic jack, solves work intensity large, inefficiency and can not adapt to the problem on ground of different condition.
The technical solution of the utility model is: a kind of hydraulic jack, comprises oil-feed fuel tank, hydraulic actuating cylinder, oil return fuel tank, oil-feed oil pump, oil return oil pump, check valve, shutoff valve, base plate and tripod apparatus.Described oil-feed fuel tank is connected with oil suction pipe, oil-feed oil pump and check valve is connected with oil suction pipe successively between described oil-feed fuel tank and described hydraulic actuating cylinder, piston and piston rod is included in described hydraulic actuating cylinder, lower end, described hydraulic actuating cylinder side is provided with oil inlet, described oil inlet is connected with oil suction pipe, described hydraulic actuating cylinder bottom is provided with oil outlet, described oil outlet is connected with the first oil return pipe, described first oil return pipe is provided with shutoff valve, the described first oil return pipe other end stretches in oil return fuel tank, the second oil return pipe is connected with between described oil return fuel tank and described oil-feed fuel tank, described oil return oil pump is connected on the second oil return pipe, and described oil-feed fuel tank and described oil return fuel tank are fixed on base plate, described base plate mid-section bottom is provided with groove, described tripod is arranged on base plate bottom groove place, described base plate side is provided with tripod switch.
The beneficial effects of the utility model are: use this device, and work intensity is low, and efficiency is high, and hydraulic oil can be recycled, and jack all can be firm on unfairness floor and the different bearing surface of degree of dip.

Detailed description of the invention
A kind of hydraulic jack, comprises oil-feed fuel tank 1, hydraulic actuating cylinder 9, oil return fuel tank 13, oil-feed oil pump 4, oil return oil pump 14, check valve 5, shutoff valve 11, base plate 16 and tripod 18 device.Described oil-feed fuel tank 1 is connected with oil suction pipe 3, oil-feed oil pump 4 and check valve 5 is connected with oil suction pipe 3 successively between described oil-feed fuel tank 1 with described hydraulic actuating cylinder 9, piston 7 and piston rod 8 is included in described hydraulic actuating cylinder 9, lower end, described hydraulic actuating cylinder 9 side is provided with oil inlet 6, described oil inlet 6 is connected with oil suction pipe 3, described hydraulic actuating cylinder 9 bottom is provided with oil outlet 10, described oil outlet 10 is connected with the first oil return pipe 12, described first oil return pipe 12 is provided with shutoff valve 11, described first oil return pipe 12 other end stretches in oil return fuel tank 13, the second oil return pipe 15 is connected with between described oil return fuel tank 13 and described oil-feed fuel tank 1, described oil return oil pump 14 is connected on the second oil return pipe 15, described oil-feed fuel tank 1 is fixed on base plate 16 with described oil return fuel tank 13, described base plate 16 mid-section bottom is provided with groove 17, described tripod 18 is arranged on base plate 16 bottom groove 17 place, described base plate 16 side is provided with tripod 18 switch 19.
Principle of work of the present utility model is: start oil-feed oil pump 4, hydraulic oil 2 extracting from oil-feed fuel tank 1 is come, check valve 5 is opened automatically, and hydraulic oil 2 enters in hydraulic actuating cylinder 9 by oil inlet, up promotes piston 7 move at hydraulic actuating cylinder 9 cavity of resorption, thus impel piston rod 8 to head on workpiece to move up, when moving to required height, close oil-feed oil pump 4, check valve 5 is closed automatically, hydraulic oil 2 just can not flow backwards, thus ensure that workpiece can not fall voluntarily.Work and completely will recover initial position, as long as open shutoff valve 11, hydraulic oil 2 will be back in oil return fuel tank 13 by the first oil return pipe 12, workpiece and piston rod 8 also just fall after rise to initial position, then oil return oil pump 14 is started, extracted from oil return fuel tank 13 in oil-feed fuel tank 1 by hydraulic oil 2, ensure that oil-feed fuel tank 1 oil mass is sufficient, convenient supporting workpiece next time rises to certain altitude.
When ground unfairness or bearing surface have certain angle of inclination, can open base plate 16 sidewall switch 19, tripod 18 is propped up automatically, then adjusts whole jack position as the case may be and makes it firmly.
