Optimisation Design Study of the Trough Gang Structure in the Middle Trough of Mining Scraper Conveyor
The trough gang structure in the middle of scraper conveyor bears a large load during work and is prone to failure problems.Taking SGB420/22 scraper conveyor as the research object,the finite element model of the trough gang structure was established by using ANSYS Workbench software,and it was found that the contact stresses of the upper and lower edges of the trough gang inner side were bigger,and the former was bigger,with the maximum contact stress of 12 900 Pa.The line shape of the trough gang inner side of the central trough was optimized,and the analysis of the model was established again,and it was found that the contact stresses of the upper and lower edges were bigger,and the contact stresses of the upper and lower edges were bigger,and the maximum contact stress was 12900 Pa.The contact stresses at the upper and lower edges are more uniform,and the maximum stress is reduced to 8 784 Pa,with a reduction of 19.34％.The optimised channel gang structure was put into practice for 3 months,and the effect was found to be good,and its service life was increased by more than 15％.
