Design And Research Of 6000KN Filling Hydraulic Support

With the continuous increase of environmental protection in China,the filling problem after coal mining has been paid more and more attention.The current comprehensive mining technology supported by the three machines is also difficult to improve the production of coal mines.Especially in the process of fully mechanized mining,the continuous movement of the coal mining machine,scraper conveyor and hydraulic support makes the filling operation unable to follow up in time,which causes the mining and filling operations to be carried out in shifts,thus reducing production efficiency.In view of this,this paper designs and develops a hydraulic support with a working resistance of 6000 kN and capable of simultaneously adapting to mining and filling operations.Firstly,by analyzing the actual coal mining demand of a coal mine,the frame type and overall structural parameters of the hydraulic support are determined.The rationality of the design is verified by ADAMS simulation,and the design parameters are optimized to determine the large size of the hydraulic support.The structure and dimensions of the components and the creation of a 3D model in Solid Works.Through calculation,the initial strength check of the established hydraulic support model was carried out,especially for the check of the top beam and the base,and the structural strength was determined to be within the safe range;the specific pressure of the base was checked and verified.The base specific pressure is less than the design requirements.The kinematics simulation of the filled hydraulic support was carried out by ADAMS software,and it was verified that the top elevation and the top beam swing met the design requirements.Finally,the Solid Works Simulation module is used to analyze the stress and strain of the filled hydraulic support at the two ends of the top beam,the torsion loading of the top beam and the eccentric load of the top beam.It is verified that the stress is in the material yield strength under the above three conditions.Within the scope.
