Forced lubrication indication and alarm device for scraper conveyor reducer in coal mining face

Abstract

The invention relates to the technical field of monitoring, in particular to a forced lubrication indication and alarm device for a scraper conveyor reducer on a coal mining face, including a bottom plate, a lubricating oil tank, a lubricating pump, a motor, a reducer, an indicating mechanism, an alarm mechanism and a flow rate The base plate is set horizontally, the lubricating oil tank, the lubricating pump, the motor, the reducer and the alarm mechanism are all fixedly installed on the upper part of the base plate, and the rotating shaft of the motor is connected to the The input shaft of the reducer is fixedly connected. The present invention can indicate in real time whether the oil pipes and oil passages are normally transporting lubricating oil and alarm for lack of oil, so that the staff can observe the lubrication condition of the high-speed shaft bearing of the reducer in real time, and can stop the machine in time when the lubrication is poor or lack of oil, so as to avoid Cause the high-speed shaft bearing of the reducer to fall apart and lock, which will affect the normal production of the working face, thereby avoiding the waste of manpower and material resources and large economic losses.

Description

technical field [0001] The invention relates to the technical field of monitoring, and more specifically relates to a forced lubrication indication and alarm device for a scraper conveyor reducer on a coal mining face. Background technique [0002] The high-speed shaft bearing of the scraper conveyor reducer in the coal mine fully mechanized mining face generally uses a lubricating pump to absorb lubricating oil from the oil pool, and the lubricating oil enters the bearing through the oil pipe and the oil passage inside the reducer to perform forced lubrication on the bearing. Due to the damage of the lubricating pump, the blockage of the oil pipe or oil passage, etc., the high-speed shaft bearing of the reducer is short of oil, which can cause the bearing to fall apart and lock, affecting the normal production of the working face, resulting in waste of manpower and material resources and large economic losses. [0003] Therefore, it is necessary to design a device that can ...

Problems solved by technology

Due to the damage of the lubricating pump, the blockage of the oil pipe or oil passage, etc., the high-speed shaft bearing of the reducer is short of oil, which can cause the bearing to fall apart and lock up, affecting the normal production of the working face, resulting in waste of manpower and material resources and large economic losses.

[0003] Therefore, it is necessary to design a device that can indicate in real time whether the oil pipes and oil passages are normally transporting lubricating oil and alarm the lack of oil, so that the staff can observe the lubrication status of the high-speed shaft bearings of the reducer in real time, and when the lubrication is poor or lack of oil, it can Stop in time to avoid the failure of the high-speed shaft bearing of the reducer to fall apart and lock, which will affect the normal production of the working face, thereby avoiding the waste of manpower and material resources and large economic losses
