Bucket Wheel Changeover Using Detachable Operating Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bucket wheel machine maintenance processes are time-consuming and pose safety risks due to the need for crane operations, leading to prolonged downtime and potential hazards.
Innovation Solution
A bucket wheel machine system with a detachable operating block and support frame that allows simultaneous removal and replacement of components like the bucket wheel, chute, and drive, eliminating the need for cranes by supporting the weight of the operating block during maintenance using a support structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the bucket wheel, chute, and drive are removed and replaced separately using crane operations, then the maintenance can be performed, but the maintenance time is prolonged and safety risks increase
Solution Approach 1:
The patent combines the bucket wheel, chute, and drive into a single integrated operating block that can be removed and replaced as one unit. This merging of components eliminates the need for separate crane operations for each component, significantly reducing maintenance downtime while maintaining ease of repair.
Solution Approach 2:
The patent segments the bucket wheel machine into modular components: the operating block (containing bucket wheel, chute, and drive) and the base. This segmentation allows the operating block to be detached and replaced independently, enabling faster maintenance without requiring disassembly of the entire machine.
2Ease of operation
If crane operations are used to lift and position the bucket wheel and components, then the heavy components can be handled, but safety risks for surrounding people and equipment increase
Solution Approach 1:
By merging the bucket wheel, chute, and drive into a single operating block, the patent reduces the number of separate lifting operations required. This consolidation minimizes the exposure of surrounding people and equipment to crane operations, thereby reducing safety risks while maintaining the ability to handle heavy components.
3Productivity
If the operating block is detached from the base, then the components can be replaced faster, but the operating block requires support during removal and installation
Solution Approach 1:
The patent introduces a support structure as an intermediary element that assists in the removal and installation of the operating block. This support structure provides the necessary stability and guidance during the transition states, enabling faster maintenance operations without significantly increasing overall system complexity.
