Currently, the hydraulic system of engineering vehicle such as the full Terrain Cranes are all made of the steel hydraulic oil of traditional structure both at home and abroad
Case, hydraulic oil container is a kind of special container, other than storing hydraulic oil, also distributes the effect of heat, precipitating grease.Thus liquid
When pressure oil case is in addition to cleaning fuel tank, upper cover cannot be at will opened, air filter is also set on fuel tank, is made in atmosphere and fuel tank
Air communicated by filter.Hydraulic oil container is generally by rapid refueling connector, air filter, thermometer, oil level indicator, oil suction
The main components such as self-packer, cabinet, blowdown valve composition.
By taking existing 200 tonnes of the full Terrain Cranes as an example, hydraulic oil container mainly uses one-piece steel cabinet, feature
Be: structure is simple, and handling ease realizes that cost is relatively low, but surface is gloomy coarse, needs further to be surface-treated and paint, add
Work defect is more, and weight is bigger than normal, and invalid trapped fuel is more.
Specific as follows: 1, fuel tank body material selection steel panel, steel plate material density is big, fuel tank weight, and fuel tank body is anticorrosive
Property it is poor, need to carry out spray painting protection, fuel tank increased costs, weight increase；2, tank bottoms only design an inlet port, by institute
There is hydraulic circuit oil suction, all from this inlet port oil suction, inlet port bore design comparison is big, to guarantee not suck air, it is necessary to
Guarantee the trapped fuel liquid level of fuel tank internal more than inlet port.Therefore, inlet port bore is big, causes liquid level line height high, deposits in vain
Oil mass is big, and inert weight is big；3, fuel tank internal baffle design, with fuel tank lower surface using being intermittently welded, partition is set for partition bottom
Notch is counted, partition two sides volume space inner fluid can mutually circulate.In the steering hydraulic system of double loop, one of circuit
Hydraulic fluid leak occurs, another loop hydraulic oil can also leak in leakage point, eventually lead to two steering circuits and all lose turn
To function, vehicle driving safety is influenced.

Specific embodiment
A kind of hydraulic oil tank device for crane as shown in Figures 1 to 7, including fuel tank body 1, the fuel tank body 1
Upper end be equipped with air cleaner 5 and at least two return oil filters, the lower part of the fuel tank body 1 is equipped with no less than two oil suctions
Mouthful, the lower surface 2 of the fuel tank body 1 is step type, lower side of the inlet port close to stepped lower surface 2, the oil
Partition 10 is equipped with inside cabinet 1,1 bottom of fuel tank body is divided into two mutual disconnected regions, the fuel tank body 1 by the partition 10
Side be equipped with liquid level liquid thermometer 3.
Fuel tank body of the invention is equipped at least two inlet ports, replaces a heavy caliber to inhale by multiple small-bore inlet ports
Hydraulic fluid port reduces single inlet port bore while guaranteeing hydraulic system oil absorption, reduces trapped fuel liquid level, and it is invalid to reduce
Trapped fuel liquid level reduces invalid trapped fuel, specifically refers to Fig. 6 and Fig. 7, and in Fig. 6, D is heavy caliber in the prior art suction
Hydraulic fluid port, E are the small-bore inlet port of the application, and inlet port only changes caliber size, do not change position of center line, therefore, trapped fuel
Highest scale B is dropped to by A；In Fig. 7, the aperture of inlet port not only reduces, while reducing the position of center line of inlet port installation,
Therefore the highest scale of trapped fuel continues to drop at C, and trapped fuel amount is further reduced, it is contemplated that the shape of fuel tank body bottom surface, this
The trapped fuel amount of application greatly reduces；
For fuel tank body lower surface design of the invention at stairstepping, inlet port is positioned close to lower the one of stairstepping
Side, the height of hydraulic oil is higher than inlet port topmost when use, compared with existing scheme tank bottoms are designed to planar structure, liquid
The invalid trapped fuel amount of pressure oil case substantially reduces；
Partition is set inside fuel tank body of the invention, is connected to fuel tank body bottom not, two sides oil liquid can not mutually circulate, can
A double loop steering hydraulic system is formed, circuit I is turned to and turns to circuit II in different inlet port oil suctions, different oil returns
There is oil liquid leakage when any one turns to circuit, all will not influence another and turn to circuit normal work, guarantee in mouth oil return
The safety of vehicle driving.
