Abstract
As for the conventional automatic tensioning system of scraper conveyor chain in fully mechanized mining face,its adjustment instructions are mostly single objective oriented,and the control response speed is slow,which leads to the increase of automatic tensioning delay.Therefore,the design of automatic tensioning system of scraper conveyor chain based on embedded in fully mechanized mining face is put forward.According to the automatic tensioning requirements,the electronic control equipment is first set up,and the chain embedded automatic tensioning control device is associated to complete the system hardware design.Multi-objective method is adopted to improve the control response speed,multi-objective automatic tensioning adjustment instruction is designed,and embedded interactive automatic tensioning control function module is connected to realize the design of system software.System test results show that,under different cylinder stroke,the final automatic tensioning delay of the five scraper conveyors is controlled below 0.4 s,indicating that the embedded automatic tensioning system of scraper conveyer chain in fully mechanized mining face is more efficient and more controllable in the process of application,which has practical application value.关键词
