Analysis of Force on Four-Link Mechanism of ZZ5000 Hydraulic Support
In order to further investigate how to improve the operation quality of the roof beam part of the hydraulic support,the ZZ5000 hydraulic support commonly used in coal mining enterprises is taken as the object of research.Based on the establishment of the simulation model of the hydraulic support,the up and down errors of the relative positions of the base and the front linkage hinge point,the up and down errors of the base and the rear linkage hinge point,and the up and down errors of the front and rear linkage hinge points of the cover beam,as well as the up and down deviations of the cover beam length errors are analysed from four perspectives.The results show that the optimised hydraulic support four-link rod effectively supports the improvement of the support accuracy of the hydraulic support.
