Bolt anti-loosening structure for hollow end cover of ball mill and installation method

Abstract

The invention belongs to the technical field of loosening prevention of fixed bolts of heavy machinery, and specifically relates to a bolt anti-loosening structure for a hollow end cover of a ball mill and an installation method. The anti-loosening structure comprises a hollow end cover fixed at one side of the ball mill by bolts, a strip slot is formed in the hollow end cover above the bolts, a Z-shaped fastener passes through the hollow end cover, one end of the Z-shaped fastener is clamped in the hollow end cover, and the other end of the Z-shaped fastener is clamped on the bolts; and the Z-shaped fastener is composed of an L-shaped plate and a bolt clamping block, the L-shaped plate comprises a middle connecting part and a clamping part in the end cover, and the strip slot is matched with the L-shaped plate. With an ingenious structure, simple and convenient installation and disassembly, the bolt anti-loosening structure can prevent bolts from loosening effectively during equipmentoperation, avoid equipment shutdown and accidents caused by bolts falling, improve equipment operation efficiency, and avoid equipment shutdown affecting production and safety risks. The frequent maintenance, inspection and repair to the equipment are avoided, the labor is saved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a bolt anti-loosening structure and an installation method for a hollow end cover of a ball mill, and belongs to the technical field of anti-loosening bolts for heavy-duty mechanical fixing. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. This type of grinding machine is filled with a certain number of steel balls in its cylinder as the grinding medium. The ball mill is suitable for grinding various ores and other materials, and is widely used in mineral processing. However, after the installation of the hollow end cover of the ball mill in the mineral processing plant, the bolts that fix the end cover often loosen as the mill runs. If the inspection is not timely, it will easily cause prolapse and fall off, causing equipment shutdown to affect normal production, and even cause safety accidents. .
