Design And Research Of ZZ13000/27/60D Type Powered Support With Large Mining Height

China’s coal reserves are abundant in gently inclined thick seam of coal production accounted for roughly half of the total coal production. In gently inclined thick seam mining mainly uses a full- height mechanized mining methods mining. So high hydraulic support of large mining has very important significance.Drawing on domestic large mining height hydraulic supports advanced design and manufacturing experience, based on theoretical calculations using correct, computer-aided design and method of combining practical test, design and development of ZZ13000 / 27 / 60 D type large mining height covering hydraulic four-post support bracket.Completed the overall design of the bracket, top-down design for the bracket structure is designed. Focusing on large mining height hydraulic supports four-bar linkage design with lordosis curve as the four bar linkage trajectory curve. And the use of hydraulic support design software Mai solid four-bar linkage parameters for scaffold design calculations, analysis and comparison of all the major parameters finally obtained support structure members.Mai use design software for real- hydraulic support structure cross-section of the strength check. By stent stress analysis, the final determination of the front cover of the beam in the roof beams and front hinge hole box-section, covering the beam cross-section front linkage, front and rear link-section and a base, posterior column nest-section, stress analysis and strength check. Analysis of the results, when the safety factor calculated from the corresponding structure is too large, consider using low-grade steel to replace the standard steel thickness can also be thinning, or reduce the number of ribs and other methods to strengthen. Adjust different strength steel structural members of the stent material ratio, to optimize the design, the stent can improve the carrying capacity, reduce its own weight, manufacturing cost savings.Solidworks software with three-dimensional three-dimensional hydraulic support virtual prototype design is completed, and interference checking. In this way you can improve design efficiency and quality, reduce cost of product development prototype trial.This study high hydraulic support large mining methods and conclusions have some practical engineering application value. The produc t is in the thick Coal Seam provides reliable full- height face a performance support equipment, but also for the further development of similar large mining height bracket provides a reliable reference.
