Oxygen Lance Guiding Assembly Using Drill Rod Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oxygen lance guiding assemblies require a drilling rod with a guide hole and a separate duct for the oxygen lance, complicating handling and increasing mass, especially when combined with a tap hole drilling unit.
Innovation Solution
The oxygen lance feeding device is positioned between the drilling rod guiding device and the drilling mechanism, using the drilling rod guiding device to define the oxygen lance guiding axis, allowing for a conventional drilling rod and mechanism without additional ducts, and is transferable between inoperative and operating positions via a pivoting motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the oxygen lance feeding device is disposed upstream of the drilling mechanism with a separate supply roll, then the oxygen lance can be fed through the drilling rod, but the device complexity and mass increase
Solution Approach 1:
The oxygen lance feeding device is merged with the tap hole drilling unit by positioning it between the drilling rod guiding device and the drilling mechanism. The drilling rod guiding device serves dual purposes: guiding the drilling rod during tap hole opening and guiding the oxygen lance during insertion. This eliminates the need for separate ducts in the drilling rod and mechanism, reducing structural complexity while maintaining both drilling and oxygen lance feeding functions.
Solution Approach 2:
The drilling rod guiding device is designed to perform multiple functions: it guides the drilling rod when the drilling mechanism is operational, and subsequently guides the oxygen lance after the drilling rod is removed. This multi-functionality eliminates the need for separate guiding structures for both operations, reducing overall device complexity and mass.
2Productivity
If the supply roll is disposed on the receptacle of the tap hole drilling unit, then the oxygen lance can be supplied, but the mass increases complicating handling
Solution Approach 1:
The supply roll is integrated into the existing tap hole drilling unit structure by positioning it on the receptacle alongside the oxygen lance feeding device. This merging approach allows the oxygen lance supply function to be added without requiring entirely separate support structures, minimizing the increase in overall mass while maintaining supply capability.
3Manufacturing precision
If the oxygen lance is inserted through a drilling rod with a guide hole, then the oxygen lance can be guided, but additional ducts are required in the drilling mechanism
Solution Approach 1:
The oxygen lance guiding function is extracted from the drilling rod and mechanism by using the existing drilling rod guiding device. Instead of requiring guide holes in the drilling rod and ducts in the mechanism, the oxygen lance is guided directly by the drilling rod guiding device after the drilling rod is removed, eliminating the need for additional ducts while maintaining guiding accuracy.
Solution Approach 2:
The drilling rod guiding device serves as a universal guiding structure for both the drilling rod during tap hole opening and the oxygen lance during insertion. This eliminates the need for separate guiding ducts in the drilling rod and mechanism, reducing structural complexity while maintaining the precision required for both operations.
4Ease of operation
If the drilling rod is provided with a guide hole for the oxygen lance, then the oxygen lance can pass through, but the drilling rod design becomes more complex
Solution Approach 1:
The oxygen lance guiding function is extracted from the drilling rod itself and transferred to the dedicated drilling rod guiding device. This allows the drilling rod to maintain its simple, conventional design without guide holes, while the oxygen lance is guided by the external guiding device after the drilling rod is removed from the tap hole.
Solution Approach 2:
The drilling rod guiding device is prepared in advance to receive and guide the oxygen lance. After the drilling rod completes its function of opening the tap hole and is removed, the guiding device is already positioned and configured to guide the oxygen lance insertion, eliminating the need for modifications to the drilling rod design.

AI summary
The invention relates to an oxygen lance guiding assembly having an oxygen lance feeding device, which is disposed on a tap hole drilling unit. The tap hole drilling unit has a drilling rod guiding device for a drilling rod, which is driven by a drilling mechanism, on a receptacle configured to have the drilling mechanism disposed thereon. The oxygen lance feeding device is disposed in an operating position in a space formed between the drilling rod guiding device and the drilling mechanism in such a manner that the drilling rod guiding device serves to form an oxygen lance guiding axis.
