Embodiment Construction

[0021] like figure 1 As shown, the device for lifting the container on the railway flat car with the F-TR lock, including the twist lock force measuring module of the container spreader, the data acquisition module, the wireless or wired communication module, the PLC control module, the frequency converter, the lifting motor, lifting mechanism;

[0022] The twistlock force measuring module includes force sensor one, force sensor two, force sensor three and force sensor four installed on the four twist locks of the container spreader. The data acquisition module is respectively connected with each force sensor of the force measurement module, and reads the force value of each twistlock during the container lifting process;

[0023] The PLC control module receives the force value of each twistlock collected by the data acquisition module through the wireless or wired communication module, and processes the detection data;

[0024] The frequency converter receives the control c...

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...
