The device is inflated, the power take-off fork is engaged, the power take-off is rotated, the hydraulic cylinder is extended, and the vehicle enters the lifting state. At the same time, the rear door cylinder is extended, the lock rod is rotated, and the door lock is opened. After unloading, the box body is lowered to the bottom. , the power take-off port is exhausted, the power take-off stops working, the cylinder is retracted to drive the lock rod to reverse, and the door lock locks the container door. Therefore, relying on the cylinder lock, even after the mechanical locking device is worn, the rear door can still be closed reliably. This eliminates the hidden danger of cargo being thrown away due to loosely closing the back door.

Description

A kind of container rear door opening and closing control mechanism

Technical field

The invention belongs to the technical field of containers, and particularly relates to a container rear door opening and closing control mechanism.

Background technique

At present, bulk material transportation mostly adopts the container transportation mode. During the transportation process, it can be fully enclosed and no throwing. Compared with the previous transportation mode, environmental problems such as dust throwing are avoided. It can not only reduce cargo damage, but also promote "bulk-to-transform integration". "A new green transportation model. The container transportation model reduces enterprise transportation costs, realizes closed transportation, and promotes the "bulk-to-collection" road-to-rail intermodal transportation mode. Therefore, sand and gravel containers and bulk grain transportation containers have emerged as the times require, equipped with self-unloading Semi-trailers greatly improve transportation efficiency.

The back doors of existing sand and gravel containers and bulk grain transport containers all use manual opening and closing structures. Before unloading, people need to manually open the back door. After unloading, people need to manually close the back door. The operation is cumbersome. After the manual mechanical locking structure is used for a period of time, There are many faults, and there are problems such as the back door not closing tightly.
