Coal face scraper conveyor speed reducer forced lubrication indicating and alarming device

Abstract

The invention relates to the technical field of monitoring, in particular to a coal face scraper conveyor speed reducer forced lubrication indicating and alarming device. The coal face scraper conveyor speed reducer forced lubrication indicating and alarming device comprises a bottom plate, a lubricating oil tank, a lubricating pump, a motor, a speed reducer, an indicating mechanism, an alarming mechanism and a flow meter, wherein the bottom plate is horizontally arranged, the lubricating oil tank, the lubricating pump, the motor, the speed reducer and the alarm mechanism are all fixedly installed on the upper portion of the bottom plate, and a rotating shaft of the motor is fixedly connected with an input shaft of the speed reducer. The device can indicate whether an oil pipe and an oil duct convey lubricating oil normally or not in real time and give an oil shortage alarm, so that a worker can observe the lubricating condition of a high-speed shaft bearing of the speed reducer in real time, the device can be stopped in time when lubrication is poor or oil shortage occurs, and normal production of a working face is prevented from being influenced by a falling-apart locking fault of the high-speed shaft bearing of the speed reducer, so that waste of manpower and material resources and larger economic loss are avoided.

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
