Slipform Paver Conveyor Collision Zone Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of slipform pavers and their conveyor devices is complex, requiring operators to control both the paver and the conveyor, which increases the need for simplification to enhance efficiency and safety.
Innovation Solution
A control device is implemented to define a collision area within the movement space of the conveyor device, using actuators and sensors to position and control the conveyor device, outputting control signals for warnings or stops to prevent collisions, and allowing for manual or automatic adjustment of the collision area based on changing machine configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conveyor device is made movable and adjustable within a movement space, then the adaptability and versatility of the slipform paver is improved, but the device complexity and operational difficulty increase
Solution Approach 1:
The conveyor device is designed to be dynamically movable within a defined movement space relative to the machine frame, allowing it to adapt to different material sources and work positions. This dynamic capability enables the conveyor to pivot about horizontal and vertical axes, transforming the system from static to adaptive configuration
Solution Approach 2:
The movable conveyor device serves multiple functions: it can receive material from different locations, transport it to various work positions, and adjust its configuration based on operational requirements. This multi-functionality allows a single conveyor system to handle diverse paving scenarios without requiring multiple specialized conveyors
2Adaptability or versatility
If the conveyor device is made movable and adjustable, then the adaptability is improved, but the ease of operation deteriorates
Solution Approach 1:
A control device continuously monitors the position of the movable conveyor device within the movement space and provides feedback control. This ensures that the conveyor remains positioned safely within defined boundaries while automatically adjusting for minor position variations, reducing the operational burden on the operator
Solution Approach 2:
The control device acts as an intermediary between the operator and the complex movable conveyor system. It manages the coordination of multiple actuators and position adjustments, translating simple operator commands into coordinated movements of the conveyor device while maintaining safety constraints
3Reliability
If a control device with collision detection is implemented, then the safety is improved, but the device complexity increases
Solution Approach 1:
The control device pre-defines collision-free zones within the movement space before operation begins. By establishing these protected areas in advance, the system proactively prevents collisions rather than merely reacting to them, reducing the need for complex real-time collision detection and response mechanisms
Solution Approach 2:
The control device performs preliminary positioning and boundary setting of the conveyor device within the movement space. By pre-establishing safe operating parameters and collision-free zones, the system prepares the operational framework before material handling begins, simplifying ongoing safety management
