Split Flushing Element for Rock Drill Shank Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rock drilling machines face challenges in mounting and replacing shank adapters due to conventional axial mounting methods, which restrict the independent dimensioning of different axial portions of the shank adapter and limit versatility.
Innovation Solution
A split configuration flushing element that surrounds the shank adapter, allowing for radial or transverse mounting and dismounting, thereby enabling the independent dimensioning of different axial portions of the shank adapter and facilitating easier replacement of worn components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional axial mounting method is used for shank adapter, then the flushing element structure is simple, but the outer diameters of different axial portions of shank adapter are restricted and versatility is limited
Solution Approach 1:
The flushing element is divided into multiple separable parts (first flushing element part and second flushing element part) that can be assembled together. This segmentation allows the shank adapter to be mounted in radial direction with greater freedom in dimensioning different axial portions, while the modular structure keeps the overall system manageable and maintainable.
Solution Approach 2:
The mounting direction is changed from conventional axial direction to radial direction. This dimensional change enables the shank adapter to pass through the flushing element from the side rather than from the end, allowing independent dimensioning of different axial portions and improving versatility without significantly increasing complexity.
2Ease of operation
If conventional axial mounting method is used for shank adapter, then the flushing element structure is simple, but the mounting and replacement process is difficult and time-consuming
Solution Approach 1:
The flushing element is divided into multiple separable parts that can be easily assembled and disassembled. This segmentation enables quick mounting and replacement of the shank adapter by allowing access from the radial direction, significantly improving ease of operation while maintaining reasonable structural complexity through modular design.
Solution Approach 2:
By changing the mounting direction from axial to radial, the patent enables easier access to the shank adapter for mounting and replacement operations. The radial mounting approach allows technicians to work from the side of the drilling machine rather than dealing with constrained axial access, greatly improving ease of operation.
3Adaptability or versatility
If split configuration flushing element is used, then the outer diameters of shank adapter can be dimensioned freely, but the flushing element requires radial or transverse mounting instead of conventional axial mounting
Solution Approach 1:
The patent implements radial or transverse mounting instead of conventional axial mounting by changing the orientation in which the shank adapter passes through the flushing element. This dimensional change enables free dimensioning of outer diameters of different axial portions while the split configuration of the flushing element facilitates this alternative mounting approach.
4Reliability
If split configuration flushing element is used, then the flushing sealings receive axial and radial support, but the flushing element structure becomes more complex with multiple parts
Solution Approach 1:
The flushing element is segmented into multiple parts that collectively provide both axial and radial support for the flushing sealings. The first and second flushing element parts work together to create a structured environment that ensures proper support and positioning of sealings, improving reliability while the modular nature keeps complexity manageable.

AI summary
A flushing element, rock drilling machine and method of providing a flushing space around a shank adapter of a rock drilling machine. The flushing element surrounds the shank adapter passing through it. The flushing element has a feed opening for feeding flushing agent to the flushing space and at least two sealing housings for flushing sealings and wherein the flushing sealings are on opposite axial sides of the flushing space. Furthermore, the flushing element has split configuration whereby it is mountable and demountable in radial direction.
