Displaceable Covering Element for High-Pressure Blasting Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing markings and applications from paved surfaces, such as high-pressure blasting, often damage sensitive components like bitumen joints and transverse joints due to the high-pressure jet, leading to potential damage and slowed process speed.
Innovation Solution
A module with a fastening device, a displaceable covering element, and a displacement device that allows relative movement between the covering element and the fastening device, positioned between the spray nozzles and sensitive sections to shield them from the blasting agent, ensuring protection without impeding the milling process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-pressure blasting is used to remove markings from paved surfaces, then the removal efficiency is improved, but sensitive components like bitumen joints and transverse joints are damaged
Solution Approach 1:
The milling device is divided into multiple functional segments: a working unit with spray nozzles for blasting, and separate covering units with protective elements that can be positioned over sensitive components. This segmentation allows the blasting operation to proceed efficiently on non-sensitive areas while sensitive areas are protected by individual covering elements.
Solution Approach 2:
Protective covering elements are introduced as intermediary components between the high-pressure blasting agent and the sensitive paved surface components. These covering elements act as mediators that absorb or deflect the blasting agent, preventing direct contact with and damage to bitumen joints and transverse joints while allowing the blasting operation to continue.
2Object-affected harmful factors
If protective covering is applied to sensitive sections, then damage to sensitive components is prevented, but the process speed of the milling operation is reduced
Solution Approach 1:
The covering units are designed with displaceable protective elements that can dynamically adjust their position. The protective elements can be quickly moved into position over sensitive components when needed and retracted or displaced when not needed, allowing the milling device to maintain high process speed while providing protection only when and where required.
Solution Approach 2:
The protective covering elements are pre-positioned or quickly deployable before the blasting agent reaches sensitive components. This preliminary action ensures that protection is in place just in time, minimizing the time the covering elements obstruct the blasting operation and maintaining overall process speed.
3Object-affected harmful factors
If a fixed protective barrier is used to shield sensitive sections, then sensitive components are protected from high-pressure jets, but the milling device cannot operate freely and process speed is slowed
Solution Approach 1:
The protective elements are designed to be displaceable rather than fixed, allowing them to move relative to the milling device and the paved surface. This dynamic design enables the protective elements to adapt to the movement of the milling device, maintaining protection while allowing free operation without obstruction.
Solution Approach 2:
The covering units are integrated into the milling device structure and automatically follow or adjust with the device's movement. The protective elements self-adjust to maintain their protective function without requiring separate control or intervention, allowing the milling device to operate freely while protection is maintained.
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
Effectively prevents damage to sensitive sections while maintaining the speed and efficiency of the demarcation or removal process, allowing the milling device to operate unhindered while protecting vulnerable areas from high-pressure jets.
Implementation Method 1
blasting agent is fed under high pressure through the spray bar to the spray nozzles and discharged in the direction of the road. The blasting agent applied under high pressure to the paved surface or road serves to detach the road marking from the roadway.
Implementation Method 2
The blasting agent applied under high pressure to the paved surface or road serves to detach the road marking from the roadway.
Implementation Method 3
the at least one covering element is located in the vertical direction between the joint and the spray nozzles for discharging the jet of blasting media, so that the jet of blasting media impinges on the covering element but not on the sensitive component of the fixed surface.
