Centralized automatic lubricating device for coal mine belt conveyor

Abstract

The invention relates to a centralized automatic lubricating device for a coal mine belt conveyor. The centralized automatic lubricating device comprises a lubricating oil tank, a lubricating pipeline, a temperature sensor and a central control unit, wherein a liquid level sensor is arranged in the lubricating oil tank and used for detecting the oil level height of lubricating oil in the lubricating oil tank, and the lubricating oil in the lubricating oil tank is conveyed into a bearing chamber through the lubricating pipeline by a pump arranged on the lubricating oil tank; the lubricating pipeline comprises a plurality of lubricating pipelines, pressure changes in the lubricating pipeline are detected through pressure sensors arranged on the lubricating pipelines, and a flow meter is arranged at the tail end of each lubricating pipeline and used for detecting the lubricating oil flowing out of the lubricating pipeline; the temperature sensor is arranged on one side of a bearing and used for detecting the real-time temperature of the bearing; and the central control unit is connected with the liquid level sensor, the pump, the pressure sensors, the flow meters and the temperature sensor and controls working parameters of the pump. By gradually adjusting the filling speed, the labor intensity of work can be well relieved, accurate filling is conducted, and the filling efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of belt conveyors, in particular to a centralized automatic lubricating device for belt conveyors in coal mines. Background technique [0002] For the bearing lubrication of the pulley of the underground belt conveyor, at present, the lubrication of the bearing is mainly achieved by manual and regular filling of grease. The problems caused by this are: every time the grease is added, it is also a standard indicator for filling for the sake of safety. , fill the bearing chamber with grease until new clean grease overflows. There are two negative effects brought about by this: one is that the amount of lubricating grease added each time is excessive, resulting in a huge waste of lubricating grease, and also brings huge pollution to the environment; the excessive amount of lubricating grease added hinders the bearing The movement of the internal rolling elements and the cage - among the bearings, the rolling e...
