Pipeline system capable of achieving hydraulic support long-distance liquid supply

Abstract

The invention relates to a pipeline system capable of achieving hydraulic support long-distance liquid supply, and belongs to the technical field of coal mine long-arm working face fully-mechanized coal mining production. The pipeline system is composed of a main liquid inlet pipeline system, a main liquid return pipeline system and a spraying pipeline system. Each pipeline system comprises a diverter, pipelines, pipeline connectors, a reducer tee, a safety valve, a bypass hose, a pressure gauge, a pressure gauge switch, a multi-groove type high-pressure flat-plate brake valve, a mining U-shaped pin type quick connector, converters, universal bends and multi-angle bends, wherein the mining U-shaped pin type quick connector is used for being connected with a hose assembly or other hydraulic parts to enable working liquid to flow or block the working liquid, the mining U-shaped pin type quick connector is connected through U-shaped pins, the converters are used for transition connection of metal pipelines and hoses, and the universal bents and the multi-angle bents are used for transition of a complex roadway. Due to the adoption of the structure, long-distance split type arrangement of a pump station and a power station of a coal mine fully-mechanized coal mining working face liquid supply pipeline and a coal mining face is achieved, pressure detection and control of the liquid supply pipeline is achieved, equipment and the pipeline can be rapidly and conveniently installed and maintained, and meanwhile simultaneous long-distance liquid supply of a plurality of working faces is achieved.

Description

technical field [0001] The invention relates to a pipeline system capable of realizing long-distance liquid supply of a hydraulic support, and belongs to the technical field of production of long arm working faces in fully mechanized coal mining. Background technique [0002] Hydraulic support is one of the important supporting equipment for fully mechanized coal mining face, and its safety and reliability is one of the key factors that determine whether the working face can be produced safely and efficiently. It is a hydraulic power device that is moved to carry out roof support and management. Its power source is the use of the hydraulic system of the emulsion pump station to meet the needs of the hydraulic support for the emulsion through the delivery of the liquid supply pipeline. [0003] The traditional fully mechanized coal mining technology adopts a short-range liquid supply system, that is, the emulsion pumping station system, electrical control system and hydraulic...
