Quay Crane Inspection Device Rotary Switching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current container inspection systems at ports are inefficient due to the need for a dedicated scanning area, which occupies space, slows down container circulation, and risks safety from prohibited items, with limited stations further reducing efficiency.
Innovation Solution
A container inspection system with a rotary switching mechanism on a quay crane allows the inspection device to rotate 180 degrees between multiple stations, enabling flexible scanning positions and reducing the need for a separate inspection area, thus improving efficiency and safety by allowing continuous scanning without transferring containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If containers are transported to a dedicated scanning inspection area after unloading, then scanning inspection can be performed, but large space is occupied and long time is consumed, reducing container circulation efficiency
Solution Approach 1:
The patent combines the scanning inspection function with the quay crane by integrating the inspection device directly onto the crane structure. This allows containers to be inspected during the loading/unloading process without requiring separate transportation to dedicated inspection areas, thereby eliminating space occupation and time consumption associated with separate inspection facilities while maintaining reliable scanning inspection capability
Solution Approach 2:
The quay crane is designed to perform multiple functions: it serves both as a loading/unloading device and as a scanning inspection device. The inspection device integrated on the quay crane enables the crane to simultaneously handle container movement and security inspection, improving container circulation efficiency by eliminating the need for separate inspection stations and reducing overall processing time
2Productivity
If only one station for scanning inspection is provided, then the system is simple, but scanning inspection efficiency is greatly limited, resulting in large accumulation of containers
Solution Approach 1:
The inspection platform is divided into multiple inspection stations (first inspection station, second inspection station, etc.) arranged at different positions. The inspection device can switch between these stations to inspect different containers simultaneously or sequentially, thereby greatly improving scanning inspection efficiency and reducing container accumulation without requiring an overly complex single-station system
Solution Approach 2:
The patent employs a switching mechanism that enables the inspection device to dynamically move between multiple inspection stations. This dynamic positioning capability allows the system to flexibly allocate inspection resources, handle multiple containers in parallel or sequence, and maintain high inspection efficiency while managing device complexity through modular station design
3Reliability
If a dedicated scanning inspection area is established, then prohibited cargo can be detected, but the area occupies large space and creates safety hazards by allowing dangerous items to enter the yard
Solution Approach 1:
The scanning inspection is performed before containers are moved to the yard or during the unloading process at the quay crane. By conducting inspection in advance at the dock area, the system detects prohibited cargo before it can enter the yard, thereby maintaining reliable detection capability while preventing safety hazards associated with storing potentially dangerous items in the yard area

AI summary
The disclosure relates to a container inspection system, a port facility, and a box inspection method. The container inspection system comprises a quay crane (100) and an inspection device (200), wherein the quay crane (100) comprises a first hoisting component (101) and an inspection platform (103) provided with a plurality of stations, the first hoisting component (101) being configured to hoist a container (300) and transporting the container (300) to at least one of the plurality of stations; and the inspection device (200) is disposed on the inspection platform (103) and configured to switch among the plurality of stations, to perform scanning inspection on the containers on the plurality of stations, respectively. The port facility comprises the container inspection system. The inspection position of the container inspection system in the present disclosure is more flexible. The inspection device is not limited to scanning inspection at a specific station. After finishing scanning inspection on the container on one of the stations, the inspection device may turn to another station and perform scanning inspection on the container on the another station, thus being beneficial to improving the efficiency of scanning inspection.
