Guide Fixture With Curved Plates for Coke Oven Block Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Precast blocks in coke ovens are difficult to install accurately due to their large and heavy nature, leading to potential misalignment in the battery direction, which can cause unevenness in carbonization chambers and hinder smooth coke discharge.
Innovation Solution
A guide fixture comprising two guide plates with outward-flaring curved portions and a connecting body to sandwich and align precast blocks, allowing precise positioning and installation without misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If precast blocks are suspended and lowered by a traveling crane for installation, then the installation process can be performed, but misalignment in the battery direction occurs making it difficult to install accurately
Solution Approach 1:
A guide fixture is introduced as an intermediary device between the traveling crane and the precast block. The guide fixture includes guide plates with curved portions that contact the precast block and guide it into proper alignment with the combustion chamber during installation, eliminating misalignment issues while maintaining the crane-based suspension method
Solution Approach 2:
The guide fixture is attached to the precast block before suspension and lowering operations. The curved portions of the guide plates are pre-positioned to engage with the precast block, ensuring that alignment correction occurs automatically during the lowering process rather than requiring manual adjustment during installation
2Ease of manufacture
If precast blocks are used instead of refractory bricks to reconstruct combustion chambers, then reconstruction can be performed, but the large size and weight make accurate positioning difficult
Solution Approach 1:
The guide fixture acts as a mediator between the heavy precast block and the installation environment. The guide plates with curved portions provide mechanical guidance that constrains the block's movement path, enabling precise positioning despite the block's large size and weight that would otherwise make manual positioning impractical

AI summary
A problem to be solved by the present invention is to allow a precast block (PB)to be easily installed without misalignment in a battery direction (SD). A guide fixture (5, 6) includes: two guide plates (51, 61) capable of sandwiching a precast block (PB) for a coke oven (1); and a connecting body (52, 62) configured to connect the two guide plates (51, 61) opposing one another. The two guide plates (51, 61) each include a curved portion (512, 612) having an end portion flaring outward.
