Cleaning and oil changing equipment for mining speed reducer and using method of cleaning and oil changing equipment

Abstract

The invention relates to cleaning and oil changing equipment for a mining speed reducer, which belongs to the field of mechanical oil changing equipment, realizes cleaning of the interior of a gear box and replacement of gear oil through single-power bidirectional pumping of a medium, is non-standard automatic equipment with coal safety qualification, and realizes cleaning of the interior of the gear box and replacement of gear oil through single-power bidirectional pumping of the medium. The equipment structure is simplified, the cleaning mode combining cleaning, quantitative oil change, physical cleaning and chemical cleaning of the underground gearbox of the coal mine can be achieved, cleaning is more efficient, the automatic operation level is high, and the current situation that no product can be used in the cleaning and oil change operation of an underground speed reducer is changed. Physical and chemical cleaning dual effects are achieved, cleaning is efficient and thorough, a PLC program and an overflow valve are used for dual protection of pressure intensity, safety is high, and manual misoperation can be avoided due to the fact that an automatic control element is additionally arranged.

Description

technical field [0001] The invention belongs to the field of mechanical oil changing equipment, in particular, the invention relates to a cleaning and oil changing equipment for a mine reducer. Background technique [0002] The reducer is one of the important components of various large-scale equipment such as scraper conveyors, belt conveyors, and reloaders in the fully mechanized mining face of coal mines. These devices have large power, large transmission ratio, and high load. The cleaning and maintenance process must be kept perfect, so as to reduce the failure rate and repair rate of the downhole reducer. It can be achieved by replacing the lubricating oil inside the reducer. The cleaning of the deposits inside the reducer and the replacement of the lubricating oil inside the reducer in coal mines are all done manually. First, discharge the old oil in the reducer through the oil discharge port, then manually add new oil from the oil inlet to flush the deposits inside t...

AI Technical Summary

Problems solved by technology

First, discharge the old oil in the reducer through the oil discharge port, then manually add new oil from the oil inlet to flush the deposits inside the reducer, and add new oil directly after flushing, which is inconvenient, unscientific and unsafe , low efficiency, and incomplete cleaning; therefore, it is very necessary to develop a set of mine cleaning and oil change equipment with coal safety qualifications for the cleaning and maintenance of coal mine reducers
