Method of preventing feet from being directly hurt by single column

Abstract

"A method for preventing direct damage to the foot by a single column" relates to a method for preventing pinching and crushing injuries of a single column, specifically a support collar, which belongs to the field of coal mine safety; The structure of the gap ring on the outer surface of the single column achieves the above purpose. Specifically, the support ring is a double-layer hollow structure, the inner layer is a plastic ring that is placed on the outer surface of the single column, and the outer layer is a resin ring. The inner ring and the outer ring are combined. The thickness is 150mm, the inner ring and the outer ring are both 80mm wide, and the thickness of the inner ring and the outer ring are 30mm respectively; after use, it can prevent the single column from clinging to the ground or other equipment when it falls, After a fall or contact with other equipment, through the slipped gap, the hazard of the single column directly hitting the feet is reduced, and at the same time, the feet are protected to prevent the single column from directly hitting the human feet and causing damage to the instep.
