Head sheave lubricating device of mine hoist

Abstract

The invention belongs to the technical field of mine hoists, and particularly relates to a mine hoist head sheave lubricating device which comprises a wheel shaft, a wheel body is fixedly connected to the surface of the wheel shaft, two bearings are arranged on the surface of the wheel shaft, oil injection pipes are arranged at the tops of the two bearings, and two connecting plates are fixedly connected to the surface of the wheel shaft. And an L-shaped scraping plate for cleaning the bearing is arranged on one side of each connecting plate. The technical means that the wheel body and the L-shaped scraping plate are matched is adopted, the L-shaped scraping plate is conveniently driven to scrape off redundant lubricant on the surface of a bearing through rotation of the wheel body, directional recovery of the lubricant is achieved through the preset inclined holes in the scraping-off process, the lubricant and impurities are conveniently separated through the filter plate in the recovery process, and the recovery efficiency is improved. After being filtered, the lubricant only circulates in a closed channel formed by the oil storage groove and the flexible coating plate and does not make contact with external coal dust and rock debris, so that the problems of equipment clamping stagnation, part abrasion and the like caused by impurities are effectively avoided, and then the elevator can be conveniently used in an underground coal mine.
