Pumping Apparatus Damping Means for Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pumping apparatuses for materials like concrete transmit high vibrations and oscillations to the bearing structure, leading to mechanical stress, premature deterioration, and instability, especially when used on heavy vehicles with extended outlet pipes, posing safety risks.
Innovation Solution
The introduction of damping means, comprising multiple damper elements made of elastic materials like rubber, strategically positioned between the pumping unit and the bearing structure to absorb and prevent the translation and roll of the pumping unit, thereby reducing vibrations and improving stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the pumping unit is rigidly attached to the bearing structure, then the structural strength and stability are improved, but high vibrations and oscillations are transmitted to the bearing structure, causing mechanical stress and premature deterioration
Solution Approach 1:
The patent introduces a bearing assembly as an intermediary component between the pumping unit and the bearing structure. This bearing assembly includes damping elements that absorb and reduce vibrations and oscillations generated by the pumping unit, preventing them from being transmitted to the bearing structure while still maintaining structural support and stability.
2Object-affected harmful factors
If damping elements are added to reduce vibrations, then the transmission of vibrations to the bearing structure is reduced, but the device complexity increases
Solution Approach 1:
The patent merges the damping function with the bearing support function by integrating damping elements into the bearing assembly. This combination allows the same structural component to serve dual purposes: supporting the pumping unit and reducing vibrations, thereby minimizing the increase in device complexity while achieving effective vibration reduction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly reduces vibrations transmitted to the bearing structure, enhancing the stability and durability of the vehicle, ensuring safer and more precise operation, especially when the outlet pipe is extended.
Implementation Method 1
damping means interposed between the pumping unit and the bearing structure in order to dampen at least the roll of the pumping unit
Implementation Method 2
