Sliding advance of support integrated top beam combined suspension hydraulic bracket and method for sliding advance of support

The invention discloses a sliding advance of support integrated top beam combined suspension hydraulic bracket and a method for sliding advance of support and belongs to the technical field of mine support devices. The sliding advance of support integrated top beam combined suspension hydraulic bracket comprises a support beam, a top beam, hydraulic stand columns and a top beam moving jack, wherein the lower end of the top beam is hinged to four hydraulic stand columns; a hydraulic control system formed by the four hydraulic stand columns comprises a high-pressure liquid supply pipeline and a low-pressure liquid supply pipeline; the high-pressure liquid supply pipeline is used for ensuring normal working support force during normally supporting by the hydraulic stand columns; the low-pressure liquid supply pipeline is used for providing support force for moving while supporting a top plate by the hydraulic stand columns during sliding advance of support by the hydraulic stand columns; the sliding advance of support of the integrated top beam combined suspension hydraulic bracket is completed by the four hydraulic stand columns. The technology of the invention overcomes the technology prejudice and solves the problem of the sliding advance of support of the integrated top beam combined suspension hydraulic bracket; the support of the bracket is improved; the bracket moving speed is increased; the application range of the device is widened.
