Development of test platform for electrical components of JOY continuous shearer and shuttle car
In order to solve the problem that the electrical components of imported JOY continuous shearer and shuttle car cannot be tested before assembly,which will affect the operation stability and reliability of the electric control system of the whole machine after assembly,resulting in high maintenance and rework rate of the equipment and electric control system.The equipment maintenance center of Shendong Coal Group redesigned and manufactured electrical component test platform(including electrical system design,display mode,load and signal feedback mode,test bench construction)to build the elec-trical communication and control circuits of continuous shearer and shuttle cars for single or joint testing of components.Ac-cording to the measured data,when the test platform is used for single or joint testing of maintenance components,the fault detection rate of components can reach 100%,and the rework rate of equipment can be reduced to 2.4%,which is esti-mated to reduce the cost of maintenance,parts and personnel by 770000 yuan per year.Overall,the test platform is safe,re-liable and cost-effective.
