Description

Technical Field

[0001] The present invention relates to the technical field of oil pressure detection for the gearbox of a continuous rolling mill, and particularly to an automatic alarm device for the oil pressure of the gearbox of a continuous rolling mill. Background Art

[0002] During the use of a continuous rolling mill, it is necessary to continuously supply oil to the gearbox of the continuous rolling mill to maintain the lubrication effect of the gears in the gearbox. Usually, an oil tank for containing oil is externally connected to the gearbox, and the oil is slowly squeezed into the gearbox through the continuous pressure in the oil tank. In the prior art, after the traditional oil tank is connected to the gearbox, the internal pressure is often too large or too small, resulting in too fast or too slow oil delivery, thus affecting the oil use effect of the gearbox. Moreover, when the pressure in the oil tank is too large or too small, it is impossible to timely remind the staff to adjust it, further affecting the use of the gearbox oil. For this reason, we propose an automatic alarm device for the oil pressure of the gearbox of a continuous rolling mill to solve the above problems. Summary of the Invention
