TECHNICAL FIELD
[0001] The utility model relates to hot continuous rolling roller bed technical field, concretely is a roller bed oil supply pipeline detection device. BACKGROUND
[0002] In hot continuous rolling, the CSP layer cold roller bed functions to convey finished strip steel into a coiler. Each roller bed is driven independently, and the roller surface directly contacts the surface of the finished strip steel, which may scratch the strip steel when the roller bed is not rotating. Therefore, the lubrication of the roller bed is very important.
[0003] Based on the above, the present inventors found the following problems: the current hot rolling laminar flow roller bed is automatically dry oil lubricated, and the automatic dry oil lubrication is often composed of an oil pump, a double-line distributor, and an oil supply pipeline. The distributor outlet can ensure normal oil discharge during oil supply, but the oil supply pipeline is affected by external conditions, such as the loss of a clamp sleeve, corrosion, and the breaking of foreign objects, which may cause the oil supply pipeline to leak, and the roller bearing cannot be effectively lubricated. In addition, such phenomena cannot be discovered in time, which not only affects normal production, but also causes a large amount of waste of manpower and oil.
