[0002] Mining dump trucks are off-road dump trucks, mainly used for transporting ores and mineral materials in large open-pit mines. The hydraulic oil tank of a mining dump truck is an important component of the mining dump truck and is a container for storing hydraulic oil.

[0003] The hydraulic oil tank of a mining dump truck is a container for storing hydraulic oil. The atmospheric pressure respirator is a connecting element, which is generally a normal pressure direct connection structure. It connects the inside of the hydraulic oil tank with the atmosphere, and at the same time filters impurities in the air to ensure the cleanliness of the internal air. The atmospheric pressure respirator is fixed on the top or upper side of the oil tank. The atmospheric pressure respirator ensures that the inside of the hydraulic oil tank is connected to the atmosphere, and its utilization rate is extremely high. If a mining dump truck is bumpy during operation, the oil may gush out through the atmospheric pressure respirator, causing oil leakage, especially on slope sections where the oil level is tilted, the situation is more serious.

[0017] The following description sufficiently illustrates specific embodiments of the present invention to enable those skilled in the art to practice and reproduce the same.

[0018] like Figure 1 The figure is a schematic diagram of the structure of the anti-oil leakage hydraulic oil tank of the mining dump truck in the utility model.

[0019] The anti-oil hydraulic oil tank for a mining dump truck comprises: a normal pressure breathing apparatus 1, a joint 2, a cover plate assembly 3, and a hydraulic oil tank 4.

[0020] The hydraulic oil tank 4 is provided with an oil tank through hole 41 at the top, a connection port 42 is provided at the oil tank through hole 41 , and a threaded hole (threaded blind hole) is provided at the connection port 42 .

[0022] like Figure 2 , which is a schematic structural diagram of the cover plate assembly 3 in the present invention.

[0023] The cover plate assembly 3 includes: a cover plate screw 31, a threaded seat 32, an oil-proof cover plate 33, and a deflector tube 34; the oil-proof cover plate 33 is provided with a cover plate connecting through hole 35 and an air pressure balance through hole, and multiple cover plate connecting through holes 35 are located outside the air pressure balance through holes (two); the threaded seat 32 is connected to the upper part of the air pressure balance through hole, and the threaded seat 32 is provided with an internal threaded hole; the top of the deflector tube 34 is connected to the bottom of the oil-proof cover plate 33, and the inner wall of the deflector tube 34 is provided with multiple deflectors 36.

[0024] The multiple baffles 36 are parallel to each other, and the ends of the multiple baffles 36 are respectively connected to the inner wall of the baffle cylinder 34.

[0025] An annular boss is provided at the bottom of the oil-proof cover plate 33, and the top of the deflector cylinder 34 is welded to the annular boss.

[0026] The cover plate screw 31 passes through the cover plate connection through hole 35 and is connected to the threaded hole of the connection port 42, connecting the cover plate assembly 3 and the hydraulic oil tank 4 together; both ends of the connector 2 are respectively provided with external threads, the lower end of the connector 2 is connected to the internal threaded hole of the threaded seat 32, and the upper end is threadedly connected to the interface of the normal pressure breathing apparatus 1.

[0027] like Figure 3 The figure shows the use state of the anti-oil leakage hydraulic oil tank of the mining dump truck in the utility model.

[0028] In order to fix the anti-oil leakage hydraulic oil tank of the mining dump truck to the frame 5, a fixing device 6 is set on the hydraulic oil tank 4, and the fixing device 6 includes: a connecting longitudinal plate 61 and a steel belt 62.
