[0021] The present invention will be further described below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] As Figures 1 to 3Shown as follows: This embodiment discloses an integrated multi-functional hydraulic oil tank for engineering vehicles, including a box body 1. Specifically, an L-shaped partition plate 1-7 is provided inside the box body 1 to divide the box body 1 into a cavity A and a cavity B. A baffle plate 1-10 is provided in the cavity B. The baffle plate 1-10 is provided with through holes communicating on both sides of the baffle plate. The baffle plate 1-10 can also use a perforated plate, and its function is to prevent the hydraulic oil from shaking too much and affecting the stable operation of the equipment.

[0023] Both the cavity A and the cavity B are provided with their own independent oil return filters, oil return filters, breather valves, liquid level detection devices, and drain ports. Among them, the liquid level detection device includes a liquid level sensor 9 and a visual liquid level gauge 10. Among them, the liquid level sensor 9 is used for electronically displaying the oil quantity of the hydraulic oil; the liquid level gauge 10 is used for visually observing the hydraulic oil level. The breather valve 2 is arranged on the top of the box body 1 to balance the pressure inside and outside the cavity and enable the normal operation of the hydraulic oil tank. The drain port is arranged at the bottom of the box body 1, and a drain valve 11 can be arranged at the drain port for replacing and cleaning the oil tank. When the hydraulic oil needs to be replaced after a certain period of use, the drain valve 11 is opened to drain the oil and dirt that need to be replaced.

[0024] The cavity A of this embodiment is a steering and lifting cavity. The side of the steering and lifting cavity is provided with a main pump oil drain port 1-2 and a fan motor oil drain port 1-5, and the bottom is provided with an oil suction port flange 1-1, which are respectively communicated with each hydraulic pipeline.

[0025] The oil suction filter 7 is provided with an oil suction filter cover plate 5, and the oil suction filter cover plate 5 is sealed through an O-ring 6. The oil pump outputs the hydraulic oil through the oil suction port flange 1-1, realizing the confluence of the steering and lifting systems; the oil return filter 8 is used for the filling and filtering of the return oil of the hydraulic oil.

[0026] The cavity B is a braking and cooling cavity. The braking and cooling cavity is provided with a brake pump oil suction port 1-3, a cooling pump oil suction port 1-4, and a brake oil return port 1-6, which are respectively communicated with each hydraulic pipeline. The hydraulic oil is filled and filtered through the oil return filter 4; heat dissipation pipes 3 are arranged in the cavity. The working hot oil in the gearbox enters the braking and cooling cavity through the heat dissipation steel pipes 3 and is cooled and then output. The heat dissipation pipes 3 are preferably annular steel pipes, which increase the contact area, can be cooled quickly, and extend the service life of each hydraulic component.

[0027] A mesh heat insulation plate 12 is also provided on the side of the box body 1. A certain size of gap is reserved between the mesh heat insulation plate 12 and the box body 1, which can effectively prevent being scalded when the outside contacts the hydraulic oil tank.

[0028] An installation seat 1-8 for easy fixation is also provided at the bottom of the box body 1. The installation seat 1-8 also plays a role in enhancing the overall rigidity and strength. Furthermore, a rib plate 1-9 is also provided above the box body 1, and the rib plate 1-9 is connected to the side and top of the box body 1.

[0029] Regarding the prior art, in this embodiment, the box body 1 is divided into two independent cavities by the L-shaped partition plate 1-7. Both of these two independent cavities are equipped with independent oil return filters, oil return filters, breathing apparatuses, liquid level detection devices, and oil drain ports, and can work independently. Compared with the two independent fuel tanks used in the prior art, this embodiment reduces the manufacturing cost, and at the same time facilitates the pipeline layout, installation, refueling and maintenance. Moreover, in the present invention, the transmission oil is introduced into the brake cooling cavity through the heat dissipation pipe 3 for cooling, which improves the heat dissipation capacity and prolongs the service life of each hydraulic component.

[0030] This embodiment also discloses an engineering vehicle, which includes the integrated multifunctional hydraulic oil tank for the engineering vehicle described above.

[0031] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
