Analysis and Control Measures of AGV Trolley Grounding Column Shedding
The grounding column in the AGV car has the functions of protecting electric shock,anti-static,and ensuring the operation of the electrical system.Once it falls off,it will cause incalculable losses.According to the recent two phenomena of the grounding column falling off when pressing the grounding cable,this paper uses the fishbone diagram to analyze,and finally concludes that it is caused by the lack of welding skills of the operator,the insufficient tensile capacity and strength of the grounding column,and the assembly torque excee-ding the torque of the grounding column.Therefore,a new welding method of stud filling welding is put for-ward,the strength grade of the grounding column is improved,and the corresponding protective measures such as the assembly torque range of the grounding column are deduced.The test scheme is developed to verify the a-bove solutions,which proves that the three control measures proposed are reliable and effective.It provides a reference scheme for the preventive measures of similar products or other products involving grounding column shedding,which has important practical significance and engineering design reference.
