Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Be the structural representation of the hydraulic oil container of the utility model one embodiment shown in Fig. 1, this hydraulic oil container at least comprises casing 1 and cavity 3.Wherein, this casing 1 is for holding hydraulic oil, and it can be full-closed structure, and can be also semi-closed structure, the utility model be not limited to this.
This casing 1 is provided with oil pump suction mouth 2, during operation of oil pump from this oil pump suction mouth 2 by hydraulic oil sucking-off.In addition, this casing 1 also can be connected with the return line of hydraulic system.Abovementioned cavity 3 is arranged in casing 1, and this cavity 3 is the structure independent of casing 1.In this cavity 3 for input and output gas to change the hydraulic oil liquid level in casing 1, the bottom of cavity 3 is provided with the hydraulic fluid port passed in and out for the hydraulic oil in casing 1, and this hydraulic fluid port is lower than oil pump suction mouth.Namely in casing 1, after filling liquid force feed, the upper end of hydraulic oil liquid level higher than oil pump suction mouth 2 need be ensured, this cavity 3 hide at least partially below the liquid level of hydraulic oil.
Preferably, cavity 3 is formed by the shielding can be arranged in casing 1, and the lower ending opening of shielding can forms aforementioned hydraulic fluid port, and this cavity 3 can be made up of steel structure.As another kind of mode of execution, in order to change the hydraulic pressure oil mass in cavity, in cavity 3, be provided with air bag, this air bag is used for input and output gas to change the volume of cavity 3, and within it after blanketing gas, hydraulic oil liquid level improves.
In addition, in order to control the pneumatic work of turnover, this cavity 3 is also connected with the air valve 4 passing in and out direction for controlling gas, and air valve 4 is connected with gas holder 5, air.This air valve 4 preferably at least can realize three states, and one is cut-off state, and it two is that gas flows to the state of cavity 3 from gas holder 5, and it three is that gas flows to the state of ambient atmosphere from cavity 3.
Previous embodiment, when the operating mode needing hydraulic pressure oil mass larger, can make gas enter cavity 3, and then the hydraulic oil liquid level in casing 1 is improved (liquid level with reference to marking A place in figure 1), oil pump now can be avoided to inhale empty; And when the operating mode needing hydraulic pressure oil mass less, gas can be made emptying from cavity 3, revert to original level (liquid level with reference to marking B place in figure 1) in casing 1.
On the basis of preceding solution, because liquid level in casing 1 can according to Operating condition adjustment, thus can optimize hydraulic oil container volume and volume read-out, minimizing takes up room as far as possible, reduces hydraulic oil waste, is convenient to the space layout on overall engineering machine.
Further, preferably on casing 1, be also provided with liquid level sensor, liquid level sensor is connected by controller with air valve 4.When liquid level sensor detects that liquid level is on the low side, controller can control air valve 4, makes gas flow to cavity 3 from gas holder 5; When liquid level is higher, control action is just in time contrary, and then can realize automation and the intellectuality of Liquid level, better with the Conditions Matching of oil pump.
Except the hydraulic oil container of previous embodiment, the utility model also provides a kind of engineering machinery being provided with previous embodiment.Other structure of this project machinery with reference to technology that is existing or that improve, can not repeat this herein.
As a kind of preferred embodiment, this project machinery is concrete mixer, and the oil pump suction mouth 2 on aforementioned casing 1 is connected with the oil pump of concrete mixer, to meet the working condition of its complexity.When pumping procedure, oil pump suction is many, now to cavity 3 air feed, can improve the liquid level in hydraulic oil container; And when other needs oil mass to reduce, then make evacuate air, very convenient to use, and have reduce hydraulic oil waste, be convenient on concrete mixer space layout etc. in advantage.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
