Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle conveying devices in scanning inspection systems face challenges such as high construction costs, low pass rates, and instability during movement, particularly with platform truck, wire rope dragging, and holding wheel structures, which hinder efficient advancement and retreatment of vehicles for inspection.
Innovation Solution
A vehicle conveying device with a combined structure of a conveying platform and traction device, where the platform can be connected or disconnected from the traction device, allowing the traction device to drive the vehicle to advance or retreat, and the platform to move along a preset route, ensuring stability and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a platform truck conveying structure is used, then the inspected vehicle can be driven to advance or retreat, but the civil construction required is huge and the platform truck cannot be used as a passage when scanning is not performed
Solution Approach 1:
The conveying device is divided into separate modular components: a conveying platform and a traction device. The traction device can be detached and stored when not in use, allowing the conveying platform to function as a passage. This segmentation resolves the contradiction by enabling both vehicle conveyance capability and passage functionality without requiring permanent complex civil construction.
Solution Approach 2:
The system transitions from a static platform truck structure to a dynamic configuration where the traction device can be connected or disconnected from the conveying platform. When the traction device is connected, the system provides vehicle advancement and retreat capability. When disconnected, the conveying platform remains as a simple passage structure, reducing civil construction requirements.
2Ease of operation
If a platform truck conveying structure is used, then the inspected vehicle can be driven to advance or retreat, but it takes time to place the vehicle on the platform truck and double-vehicle relay inspection cannot be implemented
Solution Approach 1:
The upper surface of the conveying platform is designed to be substantially flush with the ground, creating an equipotential surface that eliminates height differences. This allows vehicles to be placed on or removed from the platform without requiring lifting mechanisms or creating access difficulties, significantly reducing vehicle placement time and enabling efficient double-vehicle relay inspections.
3Ease of operation
If a wire rope dragging structure is used, then the inspected vehicle can be moved reciprocally, but the movement stability is poor and double-vehicle relay inspection cannot be implemented
Solution Approach 1:
The system replaces the unstable wire rope dragging mechanism with a more reliable traction device that provides stable mechanical contact. The traction device uses a wheel carrier and elevating mechanism to firmly engage with and move the vehicle, ensuring stable reciprocating movement and enabling double-vehicle relay inspections.
4Ease of operation
If a holding wheel structure with the dragging trolley arranged on the ground is used, then the vehicle can be dragged through the scanning area, but the dragging trolley blocks more of the inspected vehicle during horizontal scanning
Solution Approach 1:
The wheel carrier is elevated to a height lower than the vehicle traveling surface but higher than the ground, moving the dragging mechanism from the horizontal plane to an intermediate vertical dimension. This dimensional change allows the conveying platform surface to remain flush with the ground for minimal blocking during scanning, while the elevated wheel carrier provides effective vehicle dragging capability.

AI summary
The present disclosure relates to a vehicle conveying device and a scanning inspection system. Wherein, the vehicle conveying device includes a conveying platform and a traction device. The conveying platform can be connected to or disconnected from the traction device. When the conveying platform is disconnected from the traction device, the traction device can drive the vehicle to advance or draw the vehicle onto the conveying platform. When the conveying platform is connected to the traction device and the vehicle is placed on the conveying platform, the traction device can drive the conveying platform to advance or retreat, thereby implementing that the vehicle advances or retreats. The present invention uses a combined structure of the conveying platform and the traction device. The conveying platform can be connected to or disconnected from the traction device. When the conveying platform is disconnected from the traction device, the traction device may drive the vehicle to advance, or may also draw the vehicle onto the conveying platform. After the vehicle is drawn onto the conveying platform and the conveying platform is connected to the traction device, the traction device may drive the vehicle to advance or retreat by driving the conveying platform.
