The invention relates to a device for disassembly, assembly and replacement of pipelines, in particular to a hydraulic-controlled device for cleaning, rapid disassembly and assembly and replacement of pipelines. The invention solves the problems of large labor intensity of operators and overlong consumed time because cleaning pieces are disassembled and replaced and pipe joints are assembled under a coal mine. The hydraulic-controlled device for cleaning, rapid disassembly and assembly and replacement of pipelines comprises a mechanical part and a hydraulic-controlled part; the mechanical part comprises a box body, an inlet connector penetratively fixed on the rear end surface of the box body and an outlet connector penetratively fixed on the front end surface of the box body; and a matched seal sleeve is connected to the front end of the inlet connector in a sealing way, and a sliding seal sleeve is connected to the outer wall of the outlet connector in a sliding sleeving way. By using the device disclosed by the invention, the problems of large labor intensity of the operators and overlong consumed time because cleaning pieces are disassembled and replaced and pipe joints are assembled under the coal mine are effectively solved, and the device is suitable for disassembling and replacing cleaning pieces and assembling pipe joints under the coal mine.
