Stripping Plate Actuator Synchronization in Road Milling Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ground milling machines face challenges in achieving trouble-free and reliable operation of the stripping plate, particularly in height adjustment and pivot movements, due to rapid changes in friction values and the need for manual adjustment, which can lead to jamming and increased wear on guiding elements.
Innovation Solution
A monitoring device with sensors is used to detect the adjustment position and speed of the stripping plate, and a control device synchronizes the actuation of hydraulic actuators to ensure continuous, parallel operation, automatically compensating for changes in friction, thus eliminating the need for manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment of the stripping plate is performed, then the friction changes can be compensated, but the operation becomes time-consuming and requires regular intervention
Solution Approach 1:
The control device automatically monitors sensor signals and adjusts the actuators to maintain synchronized stripping plate operation, eliminating the need for manual intervention and enabling the system to self-correct friction-related deviations
Solution Approach 2:
Sensors continuously monitor the position and movement of the stripping plate and actuators, providing feedback signals to the control device which automatically adjusts the system to compensate for friction changes and maintain reliable operation
2Reliability
If the stripping plate is adjusted frequently to compensate for friction changes, then operational reliability improves, but productivity decreases due to repeated manual intervention
Solution Approach 1:
The automated control system continuously monitors and adjusts the actuators without requiring operator intervention, maintaining reliable stripping plate operation while allowing the milling operation to proceed uninterrupted at full productivity
Solution Approach 2:
The sensor-based feedback system detects deviations in stripping plate position or movement and automatically triggers actuator adjustments, ensuring trouble-free operation without impacting the overall milling productivity
3Reliability
If the actuators are not synchronized properly, then the stripping plate may jam or operate unreliable, but achieving synchronization requires complex manual adjustment
Solution Approach 1:
Sensors monitor the position and movement of both actuators and the stripping plate, providing real-time feedback to the control device which automatically adjusts actuator synchronization, achieving reliable operation without complex manual adjustment mechanisms
Solution Approach 2:
The patent replaces complex mechanical synchronization mechanisms with an electronic control system that uses sensors and automated actuator control to achieve and maintain synchronized operation, reducing mechanical complexity while improving reliability
