Detachable coal mine underground pipeline connector protection device and mounting method

Abstract

The invention provides a detachable coal mine underground pipeline connector protection device and a mounting method. The device comprises a plurality of chain plates, a first connecting piece and a second connecting piece, wherein the chain plates are hinged end to end to form an annular body with a notch, the first connecting piece and the second connecting piece are hinged to the two ends of the notch of the annular body respectively, the ends, close to each other, of the first connecting piece and the second connecting piece are detachably connected, and elastic materials are laid at the ends, facing the inner side of the annular body, of the chain plates, the first connecting piece and the second connecting piece respectively. The protection device is simple in structure, and free disassembling and assembling of the protection device are achieved; the multiple chain plates are hinged end to end to form the annular body, so that the size of the protection device can be adjusted according to the specifications of a pipeline connector; the protection effect is improved; and the chain plates are high in adaptability, the storage specification range is reduced, only first connecting pieces and second connecting pieces of different specifications need to be stored, and therefore cost is lowered.

Description

technical field [0001] The invention relates to the technical field of coal mine pipeline installation equipment, in particular to a detachable coal mine underground pipeline interface protection device and an installation method. Background technique [0002] In order to ensure safe production in the coal mining industry, coal mining enterprises have invested a lot in the protection of circuits and pipelines. The underground environment of coal mines is harsh, and the frequency of damage to pipelines is high. These damages include geological disasters, human factors, and accidental impacts during equipment transportation. When damaged, it is easy to cause the interface between the pipelines to be staggered, and the staggered position will easily lead to the entry of dust, coal slag, and sewage, and the protection effect will be reduced, resulting in internal pollution of the pipeline, line wear and corrosion, etc., resulting in safety accidents. . In addition, there are m...

AI Technical Summary

Problems solved by technology

When damaged, it is easy to cause the interface between the pipelines to be staggered, and the staggered position will easily lead to the entry of dust, coal slag, and sewage, and the protection effect will be reduced, resulting in internal pollution of the pipeline, line wear and corrosion, etc., resulting in safety accidents.

In addition, there are many kinds of pipelines of different specifications underground. In order to replace the interface protection device in time, the enterprise needs to purchase and store a large number of protection devices of different specifications without specificity. The storage cost remains high, which is not conducive to economic production.
