[0002] The fully-mechanized coal mining process - a coal mining process in which coal breaking, coal loading, coal transportation, support, and goaf treatment in a coal mining face are all mechanized, also known as fully-mechanized mining. The equipment in a fully-mechanized mining face generally includes a coal shearer, a hydraulic support, and a scraper conveyor.

[0003] The main inlet and return liquid pipelines of the hydraulic support in a fully-mechanized mining face are located on the support base between two adjacent supports. During the process of pulling the support, the pipelines rub against the support base, which may cause serious wear and explosion of the pipelines, resulting in personal injury accidents.

[0006] One end of the steel wire rope is fixed to the fixed seat, the other end of the steel wire rope passes through the movable pulley assembly and the fixed pulley assembly in sequence, and is fixed to the fixator fixed to the movable pulley assembly. The fixator is used to fix the main inlet and return liquid pipelines of the hydraulic support in a fully-mechanized mining face, so that the inlet and return liquid pipelines are suspended in the air, reducing the lifting amplitude of the inlet and return liquid pipelines during the support moving process, eliminating friction with the support, and reducing or even eliminating the probability of the pipelines being broken, so as to ensure safety, thus solving the problem that the pipelines rub against the support base during the process of pulling the support, resulting in serious wear and explosion of the pipelines and personal injury accidents.

When the fully-mechanized caving hydraulic support moves the support, the pipeline moves along with the roof, and the movable ring moves along with the pipeline at the bottom of the fixed frame, thereby increasing the flexibility of the pipeline and improving the protection of the pipeline.

[0012] Wherein, the movable ring is provided with a limiting bracket, and the fixed frame has a limiting groove. The limiting bracket is located inside the limiting groove.
