Device and method for hoisting container on railway flatcar with F-TR locks

Abstract

The invention discloses a device and a method for hoisting a container on a railway flatcar with F-TR locks. The device includes a spin lock force measuring module, a data acquisition module, a wireless or wired communication module, a PLC control module, a frequency converter, a lifting motor, and a lifting mechanism. The spin lock force measuring module includes force sensors respectively installed on four spin locks of a container spreader. The data acquisition module reads the force value of each spin lock in the container lifting process. The wireless or wired communication module sends data acquired by the data acquisition module to the PLC control module in real time. The PLC control module processes detection data. The frequency converter receives a control command from the PLC control module, and outputs a speed control frequency to the lifting motor according to the control command. The lifting motor controls the action of the lifting mechanism according to the speed control frequency transmitted by the frequency converter. The action of a railway gantry crane is controlled intelligently according to the force detection results of the spin locks. A derailment accident caused by the fact that a corner piece at the bottom of a container is hooked to an F-TR lock is avoided.

Description

technical field [0001] The invention relates to the technical field of container loading and unloading safety, in particular to a device and method for lifting a container on a railway flat car with an F-TR lock. Background technique [0002] In the process of railway container transportation, in order to prevent the container from shifting and jumping up during transportation, F-TR locks (eagle head locks) are installed on the special flat cars for railway containers to lock the containers to ensure the safety of container transportation. In railway freight yards, container cranes are generally used for container loading and unloading. However, when the cargo in the container is loaded unbalanced, especially when the container is tilted longitudinally and eccentrically loaded, the lifting speed of the container is too fast, which may cause the F-TR lock to connect the bottom corner of the container. The derailment safety accident that causes the vehicle to be hoisted occurs...

In railway freight yards, container cranes are generally used for container loading and unloading. However, when the cargo in the container is loaded unbalanced, especially when the container is tilted longitudinally and eccentrically loaded, the lifting speed of the container is too fast, which may cause the F-TR lock to connect the bottom corner of the container. A derailment safety accident that caused the vehicle to be hoisted occurred, resulting in economic losses
