With the development of modern railway logistics,container transportation has become the main direction of the development of railway logistics.Reach stacker have strong mobility,high efficiency and easy operation when lifting containers,and are widely used in railway freight yard container operations.This paper combines the structural characteristics of the reach stacker to design the hook sensor required by the container overload and unbalanced load detection system.Hook type sensor realizes container weighing,over-unbalanced load detection and hoisting.Combining the operation process of the reach stacker,the force characteristics of the hook in the process of lifting the container and the requirements of the hook service life,the structure and life prediction of the hook sensor are designed.At the same time,the finite element analysis method is used to optimize the structural parameters,checking structural strength and service life of the sensor.Through the experimental verification,the sensor designed and processed in this paper has a reasonable structure,and the strength and accuracy meet the requirements.The application of this method provides a new solution for the design,processing and maintenance of the hook sensor.
