Description

A cargo ship with intelligent container unloading function

technical field

The invention relates to the field of terminal transportation and cargo loading and unloading, in particular to a cargo ship with an intelligent container unloading function.

Background technique

The strong demand for container transportation in the world and the continuous growth of container port throughput have put forward newer and higher requirements for container handling technical equipment and handling technology. requirements for dock loading and unloading productivity. Since the 1990s, with the growth of global economy and trade, the volume of container transportation has surged. Driven by strong transportation requirements and good technical and economic benefits, the high-tech, especially automation control technology of quayside hoisting machinery has been comprehensively developed. However, the loading and unloading system of the container terminal currently used has the following problems. Generally speaking, the container terminal can be divided into two parts: the front of the terminal (shore) and the rear of the terminal (yard). For the arrangement of the containers in the yard, there are two schemes, one is that the direction of the containers in the yard is parallel to the direction of the containers on board, and the direction of the containers here refers to the direction of the long axis of the containers. Another way in recent years is that the direction of the container in the yard is different from the direction of the container on the ship. In recent years, in order to improve the utilization rate of the yard crane and improve the working efficiency of the yard, the following second method is usually used to arrange the containers, namely, : The direction of the containers on the container ship is perpendicular to the direction of the containers in the yard. For transportation between the yard and the quayside crane, currently the method used is a horizontal transport vehicle powered by an internal combustion engine for transportation between the front and the rear of the terminal, i.e. for unloading, the quayside crane lifts the container from the ship Loaded on the horizontal transport vehicle, the container is transported to the yard area by the horizontal transport vehicle, and the container is lifted from the vehicle by the yard crane and arranged on the yard. For the container truck, the yard crane lifts the container from the yard and puts it on the truck, and then the horizontal transport vehicle transports the container to the bottom of the quayside crane, and the quayside crane completes the loading.
