AI Technical Summary
Technical Problem
In the existing technology, the connection and disconnection of the flange interface of the tank truck requires the frequent use of explosion-proof wrenches, which leads to inconvenience and low efficiency.
Method used
The system employs a transmission limit mechanism and a locking disc in conjunction with an explosion-proof motor drive. The automatic locking and unlocking of the flange is achieved through the coordinated movement of the hook rod and the rotating rod, reducing the required operating space.
Benefits of technology
It enables rapid locking and unlocking of flange interfaces, improving the efficiency of loading and unloading tank trucks and reducing manpower consumption and the risk of chemical damage.

Abstract
An automatic flange locking device includes a pipe flange mounted at the end of a pipe and a tank truck interface flange that docks with the pipe flange. It includes a transmission limiting mechanism mounted on the pipe, an annular locking disc along the side of the transmission limiting mechanism facing the pipe flange, and a locking mechanism for locking the tank truck interface flange along its circumference on the pipe flange. The locking mechanism includes a rotating rod rotatably mounted on the pipe flange via bearings. One end of the rotating rod extending outside the pipe flange is configured as a guide end that docks with the tank truck interface flange. The inner end of the guide end is configured as a driving tooth end that drives its swing. The portion between the guide end and the driving tooth end is configured as a sliding end. A swing block that can slide axially along the sliding section and rotates with the rotating rod is mounted on the sliding end. A hook rod for locking the tank truck interface flange is mounted on the swing block. The beneficial effect of this invention is that it can accurately lock the flange in a small space, significantly improving the efficiency of loading and unloading tank trucks.
