A tamping mechanism for a gangue filling hydraulic support comprises a swing beam, a swing beam jack, a primary telescopic beam, a primary compaction jack, a secondary telescopic beam and a secondary compaction jack. The swing beam, the primary telescopic beam and the secondary telescopic beam are box structures, the primary telescopic beam and the primary compaction jack are disposed in the swing beam, a sliding pair is arranged between the primary telescopic beam and the swing beam along the length direction of the primary telescopic beam, two ends of the primary compaction jack are respectively hinged on the swing beam and the primary telescopic beam, the secondary telescopic beam and the secondary compaction jack are disposed in the primary telescopic beam, another sliding pair is arranged between the secondary telescopic beam and the primary telescopic beam along the length direction of the secondary telescopic beam, and two ends of the secondary compaction jack are respectively hinged on the primary telescopic beam and the secondary telescopic beam. The tamping mechanism for the gangue filling hydraulic support is designed into a double-stage telescopic structure, a filling range is expanded, tamping ability is improved, sufficient tamping and filling are realized, and the problem that recesses are formed after tamping in the prior art is avoided to the greatest extent.
Description
technical field [0001] The invention relates to a hydraulic support for a comprehensive mechanized coal mining face in a coal mine, in particular to a support and filling hydraulic support, in particular to a tamping mechanism for the gangue filling hydraulic support. Background technique [0002] With the shortage of energy, the pace of coal mining in my country is accelerating, and more and more mines are facing the problem of resource depletion. Through the adoption of traditional strip mining, relocation of villages, filling mining and other technical measures, China has liberated the "three lower" coal pressing and improved the coal recovery rate. However, with the increase of mining depth, the increase of village relocation cost and the improvement of filling technology, the filling mining technology has become a trend of vigorous development. At present, the backfilling of goafs generally uses paste filling and gangue filling. The gangue needs to be tamped when fill...
