Movable Portal Frame Inspection System for Long-Distance Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable article inspection systems face limitations due to site restrictions and high pre-investment costs for infrastructure, and are not suitable for long-distance transitions, as they require specific chassis or track-based setups.
Innovation Solution
A movable article inspection system with a portal frame, wheeled traveling device, and ray-based inspection assembly that allows for long-distance transition without site-specific construction, featuring a transverse beam, vertical beams, and a steerable wheeled traveling mechanism with a radiation source and detection unit for fan-shaped scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vehicle-mounted inspection system is used, then mobility is improved, but the system is confined by road laws and regulations
Solution Approach 1:
The patent replaces the vehicle-mounted mechanical system with a portal frame structure equipped with wheeled traveling devices. This substitution allows the inspection system to operate independently of road regulations while maintaining mobility, as the portal frame can traverse various terrains and locations without being subject to vehicle traffic laws.
2Manufacturing precision
If a mobile gantry inspection system is used, then scanning inspection capability is improved, but site construction requirements increase
Solution Approach 1:
The patent transforms the static gantry structure into a dynamic mobile portal frame with wheeled traveling devices. This allows the inspection system to move to different locations without requiring permanent track construction, eliminating the need for extensive site preparation while maintaining the scanning inspection capability.
3Measurement precision
If track-based mobile gantry system is used, then inspection accuracy is improved, but long-distance transition capability deteriorates
Solution Approach 1:
The patent creates a universal portal frame system that combines inspection accuracy with mobile versatility. The wheeled traveling devices enable the system to transition to different locations independently, eliminating the need for fixed track infrastructure and enabling long-distance relocation while maintaining inspection precision through the radiation source and detection unit configuration.

AI summary
The present disclosure relates to a movable article inspection system comprising: a portal frame and a ray-based inspection assembly. The portal frame comprises: a portal frame, comprising: a transverse beam (1) located at a top of the portal frame; and vertical beams (2) located on opposite sides of the transverse beam (1) and connected with the transverse beam (1); a wheeled travelling device provided at lower ends of the vertical beams (2), for moving the portal frame; and a ray-based inspection assembly for carrying out an inspection of an article passing through the portal frame. With the movement of the wheeled travelling device, the position adjustment and the transition of the inspection assembly are realized. On one hand, there are fewer site restrictions and basically no civil construction for the inspection site, which reduces the pre-construction investment. On the other hand, the wheeled travelling device can achieve a long-distance transition and therefore has better applicability.
