Indicate.In building machinery field, the hydraulic jack of many engineering machinery is all by hydraulic system fuel feeding and driving, hydraulic system
In include the hydraulic oil tank of storage hydraulic oil, the driving cantilever of such as hydraulic crawler excavator, forearm, scraper bowl etc. is to use liquid
Press pump oil from hydraulic oil container to hydraulic jack delivery hydraulic pressure, then it is back to hydraulic oil container from hydraulic jack.So needing to hydraulic pressure
Fuel tank is ventilated, and to ensure the pressure in hydraulic oil container and external atmosphere pressure dynamic balance, makes the easily flowing of internal hydraulic pressure oil,
Can normally be passed in and out in the presence of atmospheric pressure.But if ventilation is improper, the hydraulic oil adhered in the air of discharge will be by logical
Stomata is discharged, and causes hydraulic oil to overflow the problem of leakage.
Utility model content
The utility model solve technical problem be：A kind of hydraulic jack air-breather for preventing hydraulic oil from overflowing is provided,
Ensure the pressure and external atmosphere pressure dynamic balance in hydraulic oil container, make the easily flowing of internal hydraulic pressure oil, and can effectively prevent hydraulic pressure
Oil is oozed out outside oil cylinder.
The technical solution of the utility model is：A kind of hydraulic jack air-breather for preventing hydraulic oil from overflowing, is in hydraulic pressure
Cover plate through hole is opened up on fuel tank upper cover plate, breather pipe and lower breather pipe are respectively mounted at the two ends of the cover plate through hole, it is described
Upper breather pipe lower end is provided with boss, and sealing ring is lined between boss and hydraulic oil container upper cover plate, and the cover plate through hole middle part is installed
There is dividing plate, four passages I are provided with the dividing plate, the bottom surface of the lower breather pipe is provided with base plate, is provided with the base plate
Four passages II on four passages II, four passages I on the dividing plate and the base plate are mutually staggered certain angle
Degree.
Further, in such scheme, four passages on four passages I on the dividing plate and the base plate
The angular dimension being mutually staggered is 20 °~70 °.
The beneficial effects of the utility model are：Present apparatus simple structure, it is reasonable in design, by the passage opened up on dividing plate
With the passage opened up on base plate, it is ensured that ventilation is smooth, it is ensured that pressure and external atmosphere pressure dynamic balance in hydraulic oil container, make interior
Portion's hydraulic oil easily flows；The certain angle simultaneously because passage opened up on dividing plate and the passage opened up on base plate stagger,
So can effectively prevent hydraulic oil from being oozed out outside oil cylinder with air.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
