Description

Anti-lifting detection and early warning device for loading and unloading of railway container special vehicle Technical Field The invention relates to the field of anti-lifting for loading and unloading of railway container special vehicles, in particular to an anti-lifting detection and early warning device for loading and unloading of railway container special vehicles. Background With the rapid development of the logistics industry, containerized transportation gradually becomes a trend of cargo transportation, and railway containerized transportation is also rapidly developed in railway freight. In railway container handling systems, due to the widely used F-TR locks on special scooters for railway containers, derailment accidents occur when trains are lifted during the lifting process. The F-TR lock is a novel container lock which is self-developed in China and is used for fixedly fixing a container on a special scooter for a railway container. The F-TR lock has a special eagle head structure, and three inclined planes act on corner fittings of the container, so that the F-TR lock acts, and when the lock is installed on a flat car special for the container, the eagle heads are arranged in the same direction at the same end and opposite directions at the two ends. The mounting position of the F-TR lock on the container-specific flatcar is shown in fig. 1. Compared with other locks, the F-TR lock has the advantages of simple structure, good locking property and smoothness, and the like, and is widely applied to flat cars special for containers. However, due to the special structure of the F-TR lock, the locking head is easy to be incompletely separated when the container is hoisted, so that the container is hoisted together with the flatcar, and huge economic loss and bad social influence are often brought.
