Description

Technical Field

[0001] The utility model relates to the technical field of oil tank radiators, in particular to an oil tank radiator for engineering machinery. Background Art

[0002] At present, the oil tanks basically only have the function of storing oil, and their structures are only composed of the oil tank body and the oil inlet and outlet of the tank body. As for the temperature of the oil, the external air can only cool the surface of the oil tank body, driving the oil temperature in the tank to drop. With such a structure, there is no problem in storing oil for a long time in winter. However, in the hot summer, long-term and high-pressure work will cause the oil temperature to be too high, which will also cause the loss of power of the hydraulic system, making the pressure of the entire system unstable, causing safety accidents and other problems. In engineering machinery, the oil tank also needs to use an oil tank radiator.

[0003] The current fuel tank radiator has been gradually found to have the following defects during use:

[0004] (1) The existing oil tank cooling device does not have an ideal cooling effect when cooling the oil in the oil tank. When the machine is working at high intensity, the cooling effect of the oil tank is relatively poor, which can easily affect the machine and cause safety accidents.

[0005] (2) Traditional cooling fans are connected as a whole. After a long time, a lot of dust accumulates on the cooling fan and the protective net. It is very inconvenient to clean the cooling fan, which affects the cooling effect.

[0006] (3) Traditional oil tanks are directly connected by screws. When the construction machinery is running for a long time, the screws may loosen, making the oil tank unstable, which poses a safety hazard. At the same time, it is very inconvenient to disassemble and install the oil tank. Utility Model Content

[0015] As an improved technical solution, wherein: the threaded rod passes through the inside of the through hole, the anti-loosening spring is arranged between the T-block and the flower-shaped plate, and the two ends of the anti-loosening spring are not fixed.

[0016] After adopting the above technical solution, the beneficial effects of the utility model are:

[0017] The utility model uses an oil pump to circulate and extract oil through a connecting pipe, and cools the hot oil through cooling water inside the water storage chamber.
