Embodiment Construction

[0012] When in use, insert the monocolumn gap ring from the bottom of the monocolumn, and the inner ring 1 is close to the outer wall of the monocolumn. When the monocolumn falls or is in close contact with other equipment, the monocolumn gap ring will first contact the ground Or contact with other equipment, so that there is a gap of about 150mm between the single column and the ground or other equipment. At the same time, the internal plastic connecting rod 4 and the expanded foam 2 after drying will play a buffer role in time, effectively preventing the single column It falls directly on the top of the human body's feet to prevent people from being injured.

[0013] The assembly method of the inner ring 1 and the outer ring 3 is as follows: heat-melt the plastic connecting rod 4 and bond it to the outer surface of the inner ring 1; The foam gun sends the expanding foam between the plastic connecting rods 4, and the expanding foam connects the outer ring with the plastic con...

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.

Description

technical field [0001] The invention relates to a method for preventing pinching and crushing of a single column, in particular to a supporting collar, which belongs to the field of coal mine safety. Background technique [0002] In coal mines, when a single column falls down and an accident occurs, it will hit people's feet, causing accidents, or when moving the single column, the single column is clamped with other equipment, and the equipment and the single column are instantly Close contact will squeeze people and cause harm to the body, which needs to be solved urgently. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a method for preventing the single column from directly hitting the foot, which can prevent the single column from falling and sticking to the ground, or from being in close contact with other equipment, and pinching the human foot. [0004] A method for preventing a single ...
