Slipform Paver Conveyor Control for Continuous Mold Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slipform pavers require operators to manually control both the paver and the conveying device, complicating the operation and making it difficult to maintain continuous loading and optimal material transfer into the concrete mold.
Innovation Solution
A slipform paver system with a controller and input device that allows operators to specify the movement of the conveying device's location, using actuators to pivot and translate the device relative to the machine frame, ensuring precise positioning and collision avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conveying device is manually controlled by the operator, then the operation can be performed, but the operation becomes complicated and difficult to control
Solution Approach 1:
The conveying device is equipped with its own control system that includes a controller, actuators, and sensors. The device can autonomously adjust its position and orientation based on input from the operator through a simplified interface, reducing the need for manual control while maintaining operational flexibility.
Solution Approach 2:
Manual mechanical control of the conveying device is replaced with an automated control system that uses electronic signals to actuate the conveying device's positioning mechanisms. This substitution simplifies the operator's task while enabling more precise and reliable positioning.
2Productivity
If the first end of the conveying device is adjusted to ensure continuous loading, then loading continuity is improved, but the position of the second end (material transfer point) must be changed as well
Solution Approach 1:
The conveying device is divided into multiple independently controllable segments or sections. Each section can be positioned and oriented independently through separate actuators, allowing the first end to be adjusted for continuous loading while the second end remains fixed or is adjusted independently to maintain optimal material transfer.
Solution Approach 2:
The conveying device incorporates dynamic positioning capabilities where different parts of the device can move independently in real-time. This allows the first end to be dynamically adjusted for continuous loading operations while the second end maintains its optimal position for material transfer, or both ends are coordinated dynamically to achieve both objectives simultaneously.
3Reliability
If the first end of the conveying device is kept in a constant position for continuous loading, then loading stability is improved, but the location of material transfer into the concrete mold cannot be optimized
Solution Approach 1:
The conveying device is segmented into independently controllable sections with separate actuators for each section. This allows the first end to be held in a constant position for stable loading while the second end can be independently positioned to optimize material transfer into the concrete mold.
Solution Approach 2:
Different parts of the conveying device have different functional requirements and positioning characteristics. The first end is optimized for stable loading with constant positioning, while the second end is optimized for material transfer with adjustable positioning. Each section has localized control mechanisms that enable this differentiated optimization.
