Abstract
The utility model relates to a hoisting device. A main oil cylinder, an auxiliary oil cylinder and an oil duct are fixed on a base seat. The utility model is characterized in that the bottom of the lower cavity of the auxiliary oil cylinder is separately connected with the plunger cavity of the main oil cylinder and an oil sump through oil ducts, and back valves are provided at the nozzles of the two oil ducts; the upper cavity of the auxiliary oil cylinder is connected with the ring oil duct on the base seat through the oil duct. The ring oil duct is separately connected with the plunger cavity of the main oil cylinder and the oil sump through oil ducts, and the two oil ducts of the ring oil duct are separately equipped with back valves. The utility model has the advantages that the structure is simple and reasonable, and the utility model is a high efficiency hoisting jack which can do bidirectional acting.
Description
The utility model relates to a kind of hoisting device.
The jack that generally uses mostly is unidirectional acting, inefficiency at present.
The purpose of this utility model provides a kind of simple and reasonable for structure, the high efficiency jack of energy two-way work doing.
The purpose of this utility model is achieved in that fixes a master cylinder, an auxilliary oil cylinder and an oil guide pipe on base, it is characterized in that: the cavity of resorption bottom of auxilliary oil cylinder links to each other with oil sump with the plunger cavity of master cylinder by oil duct respectively, and be respectively equipped with boiler check valve at two oil duct junctions, the epicoele of auxilliary oil cylinder links to each other with annular oil circuit on the base by oil guide pipe, and annular oil circuit links to each other with oil sump with the plunger cavity of master cylinder respectively by oil duct, and two oil duct junction place is provided with boiler check valve respectively.
When using the utility model, lift or press down the piston of auxilliary oil cylinder on no matter, fluid all can enter the cavity of resorption of main oil cylinder piston, thereby the piston of master cylinder successively upwards rises, so its work efficiency greatly improves.
Accompanying drawing 1 is a structural representation of the present utility model.
Working process of the present utility model is achieved in that when pressing down the piston 5 of auxilliary oil cylinder 6, with the epicoele 8 of oil,, the oil in the auxilliary oil cylinder cavity of resorption makes upwards rise of piston 2 by oil duct 14, oil suction boiler check valve 13 and oil guide pipe 7 thereby then entering master cylinder 1 plunger cavity 4 by the boiler check valve 11 that hoists, oil duct 15 from the auxilliary oil cylinder of oil cylinder 3 suctions of master cylinder; When on when carrying the piston 5 of auxilliary oil cylinder 6, by oil duct 14, oil suction boiler check valve 12 oil is sucked the cavity of resorption 9 of auxilliary oil cylinder from oil sump 3, thereby the oil of auxilliary oil cylinder epicoele 8 then makes piston 2 continue upwards to rise by the plunger cavity 4 that oil guide pipe 7, annular oil circuit 16, hoist boiler check valve 10 and oil duct 15 enter master cylinder.Go round and begin again like this, can reach the time-saving and efficiency purpose fast with object jack-up.It is compared with existing jack, and its advantage is obvious, and its cost is also near existing jack.
Mark 17 is the handle of draining the oil in the accompanying drawing 1, and mark 18 is the oil return oil duct, and mark 19 is base.
Claims (1)
1, a kind of efficient oil jack, on base, fix a master cylinder, an auxilliary oil cylinder and an oil guide pipe, it is characterized in that: the cavity of resorption bottom of auxilliary oil cylinder links to each other with oil sump with the plunger cavity of master cylinder by oil duct respectively, and be respectively equipped with boiler check valve at two oil duct junctions, the epicoele of auxilliary oil cylinder links to each other with annular oil circuit on the base by oil guide pipe, and annular oil circuit links to each other with oil sump with the plunger cavity of master cylinder respectively by oil duct, and two oil duct junction place is provided with boiler check valve respectively.
