Abstract
The utility model discloses a dumper front top closed type oil tank device which comprises an oil tank, an oil outlet, an oil filing opening and an oil return device, wherein the oil filling opening is arranged at the top of the oil tank and connected with an oil storage device. The oil outlet is arranged at the bottom end of the oil tank, the oil return device is arranged on the oil tank, and the tail end of the oil return device extends to the bottom of the interior of the oil tank. The oil outlet and the oil return device are respectively connected with an oil cylinder by a pipeline. The dumper front top closed type oil tank device further comprises a partition plate, wherein the partition plate is arranged inside the oil tank and fixedly connected with the inner wall of the oil tank, the tail end of the oil return device penetrates through the partition plate and extends to the bottom of the oil tank, and a plurality of through holes are formed in the partition plate. The dumper front top closed type oil tank device can prevent outside dust, rainwater and the like from entering the oil tank, can reduce pollution sources of hydraulic oil, greatly reduces polluted speed of the hydraulic oil, improves use time of the hydraulic oil, and is beneficial to improving reliability and service life of a dumper.
Description
Technical field
The utility model belongs to the tank mounting of dumping car, is specifically related to a kind of dumping car sinciput sealed reservoir device.
Background technique
Used dumping car sinciput hydraulic system is generally open system, only has an air-strainer to realize the filtration of air on fuel tank, and external dust is easy to enter in hydraulic oil in fuel tank, the contaminated liquid force feed.Hydraulic oil is in a single day contaminated, will form the mixture that grinds matter and enter in oil hydraulic cylinder, if these objects just are easy to by the junction point that pressure oil is pressed onto seal ring and cylinder barrel the seal ring that weares and teares, causes the generation of Seepage.In addition, when the oil hydraulic cylinder oil return or when driving, have the situation generation that hydraulic oil splashes, and the hydraulic oil that splashes contacts with air-strainer, dust in making hydraulic oil and being filled into filter cleaner mixes and forms greasy filth and air-strainer is stopped up, and is easy to cause that fuel tank is swollen snaps and cause accident; Externally the abominable mining area of environment is especially obvious for this situation.
Summary of the invention
The problems referred to above that exist in order to overcome the prior art field, the purpose of this utility model is, a kind of dumping car sinciput sealed reservoir device is provided, and solves the problem of the easy contaminated and hydraulic oil seepage of hydraulic oil in the fuel tank of present dumping car sinciput hydraulic system.
the dumping car sinciput sealed reservoir device that the utility model provides, it comprises fuel tank, oil outlet, oil filler, oil return apparatus, described oil filler is arranged on top of oil-tank, be connected with Fuel Tanking Unit, described oil outlet is arranged on the fuel tank bottom, oil return apparatus is arranged on fuel tank, and the oil return apparatus end extends to the fuel tank inner bottom part, oil outlet, oil return apparatus is connected with oil cylinder respectively by pipeline, it also comprises dividing plate, described dividing plate is arranged on fuel tank internal, be fixedly connected with inner wall of oil tank, the oil return apparatus end passes dividing plate and extends to bottom fuel tank, described dividing plate is provided with several through holes.Describedly be arranged on dividing plate in fuel tank apart from the height of the fuel tank bottom height a little more than hydraulic oil in fuel tank.
The dumping car sinciput sealed reservoir device that the utility model provides, its beneficial effect is, this device can completely cut off external dust, rainwater etc. and enter in the middle of fuel tank, can reduce the pollution sources of hydraulic oil, greatly reduce the contaminated speed of hydraulic oil, improve the service time of hydraulic oil, help to improve reliability and the life time of dumping car.
Description of drawings
Fig. 1 is the utility model embodiment's overall structure schematic diagram.
Mark in figure:
1. fuel tank; 2. oil outlet; 3. oil filler; 4. oil return apparatus; 5. dividing plate; 6. through hole; 7. hydraulic oil.
Embodiment
With reference to the accompanying drawings, in conjunction with the embodiments, the dumping car sinciput sealed reservoir device to the utility model provides is described in detail.
Embodiment
with reference to Fig. 1, the dumping car sinciput sealed reservoir device of the present embodiment, it comprises fuel tank 1, oil outlet 2, oil filler 3, oil return apparatus 4, described oil filler 2 is arranged on fuel tank 1 top, be connected with Fuel Tanking Unit, described oil outlet 2 is arranged on fuel tank 1 bottom, oil return apparatus 4 is arranged on fuel tank 1, and oil return apparatus 4 ends extend to fuel tank 1 inner bottom part, oil outlet 2, oil return apparatus 4 is connected with oil cylinder respectively by pipeline, it also comprises dividing plate 5, described dividing plate 5 is arranged on fuel tank 1 inside, be fixedly connected with fuel tank 1 inwall, oil return apparatus 4 ends pass dividing plate 5 and extend to fuel tank 1 bottom, described dividing plate 1 is provided with several through holes 6, blocking-up hydraulic oil 7 mixes with dividing plate 1 upper air, the increasing amount of air pressure when dividing plate 1 top is left large quantity space and is used for discharging the liquid level dimensional changes.Describedly be arranged on dividing plate 5 in fuel tank 1 apart from the height of the fuel tank 1 bottom height a little more than the interior hydraulic oil 7 of fuel tank 1, utilize the variation of fuel tank 1 volume to reduce the rising of the air pressure inside of fuel tank 1 airtight rear formation.
Utilize hydraulic oil 7 to cause the variation of hydraulic oil 7 volumes into and out of fuel tank 1, fuel tank 1 inner air pressure is changed, by analytical calculation, the pressure maximum that fuel tank 1 is suffered is controlled at 0.2MPa.During work, the hydraulic oil 7 in fuel tank 1 enters oil cylinder by oil outlet 2, and the air pressure in fuel tank 1 descends, and when fuel tank 1 stops fuel-displacedly, air pressure is atmospheric pressure; When hydraulic oil 7 was pushed back fuel tank 1 by oil return apparatus 4 under the pressure of compartment deadweight, air pressure increased, and when oil return was complete, the final position of hydraulic oil 7 was no more than the position of dividing plate 5, and air pressure increases to and is no more than 0.2MPa; When the hydraulic oil 7 in fuel tank 1 is not enough, refuel by oil filler 3, refuels complete after, seal oil filler 3 intact.This device can completely cut off external dust, rainwater etc. and enter in the middle of fuel tank 1, can reduce the pollution sources of hydraulic oil 7, helps to improve reliability and the life time of dumping car.
