Abstract

The invention discloses a safety unlocking control method for a train F-TR lock unloading container. The method comprises the steps that a lifting appliance lifting height value is measured in real time through a lifting appliance absolute value encoder, and the measured lifting appliance lifting height is transmitted to an automatic unlocking controller in real time; the lifting appliance rotating angle is measured in real time through a lifting appliance angle sensor, and the measured lifting appliance rotating angle is transmitted to the automatic unlocking controller in real time; and stress data of each lock head are measured through a rotary lock scale and transmitted to the automatic unlocking controller in real time, real-time unbalance loading information and the total weight of the container are obtained according to the stress data of each lock head, the difference value between the real-time unbalance loading information and the total weight and the pre-stored container weight and unbalance loading data is obtained, whether the difference value is smaller than or equal to the preset range or not is judged, and if not, the lifting appliance is forbidden to ascend. By means of the system and method provided by the embodiment, the F-TR lock unlocking efficiency and smoothness can be effectively improved, and the hidden danger that due to manual operation unlocking control precision is insufficient, accidents are likely to be enlarged after padlock hanging is avoided.

Description

technical field

[0001] The invention belongs to the technical field of container safety control, and in particular relates to a method for controlling safety unlocking of a train F-TR lock and unload container. Background technique

[0002] Container freight has the advantages of convenient loading and unloading, high transportation efficiency, and standardized specifications. As a loading and unloading operation machine and safety protection device suitable for the containerization of railway freight, F-TR lock has the advantages of simple structure, durability, locking and smoothness. Moderate and other advantages, it is currently the most used lock type for railway container flat cars. With its unique eagle head structure design, the F-TR lock solves the problems of preventing empty boxes from falling and overturning by means of binding reinforcement. However, when the container is lifted upwards from the railway flatbed transport vehicle and the F-TR lock train is unloa...
