Power-supply-free automatic lubricating and oil supplying device for elevator head sheave sliding bearing

Abstract

The invention provides a novel power-supply-free automatic lubricating and oil supplying device for an elevator head sheave sliding bearing to easily, reliably and automatically provide lubrication for the sliding bearing and reduce accidents such as the abnormal sound of a head sheave bearing bush, the high temperature and bush burning. Each half copper bush of a travelling sheave is equipped with one set of the novel power-supply-free automatic lubricating and oil supplying device, centrifugal force generated through rotation of a head sheave is used as driving force, and a piston in the novel power-supply-free automatic lubricating and oil supplying device pumps lubricating grease into the copper bushes; according to the running period of the head sheave, oil is automatically, quantificationally and continuously provided for the sliding bearing, and the good lubricating effect is achieved; and the structure is simple, the cost is low, energy conservation and environmental friendliness are achieved, and the safe and effective effects are achieved.

Description

technical field [0001] The invention relates to a hoist used in the field of mines, in particular to an automatic lubricating oil supply device without power supply for the sliding bearing of the sky wheel of the hoist. Background technique [0002] Mine hoists are currently widely used in the field of mines and are key equipment for mine hoisting and transportation. [0003] The sky wheel is the key component of the floor hoist, and it is the most stressed part in the hoisting system. However, most of the current sky wheels use copper tile structure, and the timeliness and reliability of the lubrication will directly affect the operation of the sky wheel. , thus affecting the safe operation of the entire lifting system. At present, there is a trend of heavy-duty and large-scale development of the hoist, which requires higher reliability of the hoist and the sky wheel. [0004] The sky wheel of the friction hoist is composed of two parts: the traveling wheel and the fixed ...

AI Technical Summary

Problems solved by technology

Since the sky wheel is located high in the sky and away from the ground, it is inconvenient to maintain, the labor intensity of personnel is high, and the operation is dangerous, which often leads to untimely refueling and insufficient lubrication. Lubrication failure often occurs during the operation of the equipment, resulting in abnormal noise, wear, and tile temperature of the sky wheel bearings. Accidents such as high temperature and tile burning seriously endanger the safe operation of equipment

[0006] At present, other sky wheel lubrication schemes mainly include: dry oil lubrication system using electric lubrication pump, which needs to process the sky wheel shaft into a hollow shaft, which is difficult, complicated, and expensive, and cannot be upgraded on the existing sky wheel device. Difficult to promote
