Automatic container wharf loading and unloading system and method for yard

Abstract

The invention discloses an automatic container wharf loading and unloading system for a yard. The automatic container wharf loading and unloading system comprises quay cranes, trucks and yard single-cantilever rail-mounted gantry cranes, wherein the yard single-cantilever rail-mounted gantry cranes are automatically controlled. The quay cranes are used for perpendicularly and horizontally transporting containers from a container ship to a shore side operation area. The quay cranes are arranged on the front edge of a berth, and rails of the quay cranes are parallel to the direction of a berth shoreline. A hatchway cover of the container ship is unloaded into the rails of the quay cranes from a deck of the container ship. Truck loading and unloading lanes used for conducting ship loading and unloading operation are arranged behind quay crane landside rails. The trucks are used for horizontally transporting the containers in a harbor. The single-cantilever rail-mounted gantry cranes are used for perpendicularly or horizontally transporting the containers from the quay cranes to the yard. The invention further discloses an automatic container wharf loading and unloading method for the yard. The container capacity of the container yard in the harbor is increased to a certain degree, the road service level in the harbor is effectively improved, the truck transporting distance used for the ship loading and unloading operation is effectively shortened, and the loading and unloading efficiency and the energy-saving level of the whole system are improved.

Description

technical field [0001] The invention relates to the loading and unloading technology of port container terminals, in particular to a container terminal loading and unloading system suitable for yard automation. Background technique [0002] At present, the automatic loading and unloading systems of domestic and foreign container terminal yards are mainly arranged parallel to the shoreline of the terminal (see figure 1 ), the main features of the loading and unloading system are as follows: 1) Quayside bridge is used for loading and unloading operations at the wharf; 2) Container trucks are used for horizontal transportation of containers in the port; [0003] 3) The loading and unloading operation in the yard adopts the automatically controlled double cantilever rail crane (ARMG), and the ARMG track is arranged parallel to the shoreline of the wharf; 4) The loading and unloading operations of the container trucks inside and outside the port are carried out under the cantilev...

AI Technical Summary

Problems solved by technology

Other operations of the track crane in the container yard (such as container dumping and stacking operations in the container area) adopt a fully automatic operation mode; Due to the limitation of the lateral width of the field, the loading and unloading vehicle flow must go in a "big cycle" (such as figure 2 10 and 11 in the above), it will inevitably result in a longer transportation distance for horizontal transportation equipment in the port

In addition, because each horizontal road between adjacent track cranes forms a road intersection with each vertical road in the port, the number of road intersections in the port is relatively large (see image 3 , a total of 39 intersections 50), resulting in a large decline in the service level of the roads in the port
