Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of lubricating device of the guide of cage of hoist of vertical shaft steel wire rope guide, belong to mine steel wire rope guide equipment technical field. BACKGROUND

[0002] In the production process of mine, the hoisting equipment is the key part of connecting well and underground, and bears the task of lifting, lowering personnel and materials. In the vertical shaft hoisting equipment, the guide is installed on the hoisting container and the counterweight for the steel wire rope guide, so that the hoisting container can run along the guide steel wire rope. In actual use, the guide steel wire rope and the guide rub against each other, which inevitably causes wear. The degree of wear of the guide steel wire rope and the guide is strictly regulated, and the guide needs to be replaced when it reaches the standard. To reduce wear, personnel need to manually apply oil to the worn parts regularly. Due to the high risk of shaft operation and high labor intensity, manual operation poses a serious safety hazard and affects stable and safe production. For example, the main shaft hoisting equipment of a certain iron mine uses six sealed steel wire ropes with a diameter of 50 mm. The guide of the cage is a whole structure made of cast iron. Due to the influence of the humid mine environment and heavy water spraying in the shaft, the average replacement cycle of the guide of this hoisting system equipment is about 15 days. The steel wire rope is severely corroded and worn, and its service life is nearly two years shorter than that of other mines. Therefore, the frequency of replacing the guide and the guide steel wire rope is relatively high. During the replacement and maintenance process, the shaft structure is complex, and there are significant safety hazards in the maintenance work. Due to the structure of the guide of the cage, it cannot be used when the wear reaches 8 mm, and the entire guide needs to be replaced. The service life of the guide steel wire rope and the guide of the cage is relatively short, resulting in a serious waste of spare parts.

[0003] Currently, the method of regular personnel manually applying oil to isolate water spraying and reduce the wear of the guide steel wire rope and the guide of the cage is not effective. It also increases the labor intensity of personnel, occupies a long equipment downtime for maintenance, and seriously affects the hoisting efficiency and continuous and stable production of the hoisting system. Therefore, it is necessary to design a device that can replace personnel manually applying oil to extend the service life of the guide. UTILITY MODEL CONTENTS
