Stacker Reclaimer Integration for Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacker and reclaimer arrangements lead to cross-interference issues, resulting in increased civil engineering costs, poor stress rationality of the reclaimer's upper travelling platform, and limited material stacking height, which restricts the utilization of internal storage space.
Innovation Solution
The stacker and material input conveyor are located inside the reclaimer, allowing the reclaimer to straddle the stacker and input conveyor, eliminating cross-interference and enabling a more rational stress distribution, easier maintenance, and increased storage yard utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stacker is designed outside the reclaimer to avoid cross-interference, then spatial interference is avoided, but civil engineering quantity increases and the upper travelling platform structure becomes complex
Solution Approach 1:
The patent merges the stacker and reclaimer into a integrated structure where the stacker is positioned inside the reclaimer's working space. The reclaimer's upper travelling platform serves dual functions: supporting the reclaimer mechanism and providing the stacker's travelling platform, eliminating the need for separate supporting structures and reducing civil engineering quantity.
Solution Approach 2:
The stacker is nested within the reclaimer structure, with the stacker travelling track arranged on the reclaimer's upper travelling platform. This nested arrangement allows the smaller stacker system to utilize the space and structural support of the larger reclaimer system, avoiding cross-interference while simplifying overall structure.
2Reliability
If the stacker is designed outside the reclaimer to avoid cross-interference, then spatial interference is avoided, but maintenance difficulty increases
Solution Approach 1:
By merging the stacker and reclaimer structures, the patent creates a unified maintenance platform. The reclaimer's upper travelling platform serves as the maintenance platform for both devices, providing easy access to both travelling devices from the same location and simplifying maintenance operations.
3Reliability
If the upper travelling platform is individually arranged to avoid cross-interference, then spatial interference is avoided, but stress rationality of the supporting structure deteriorates
Solution Approach 1:
The patent combines the supporting structures of the stacker and reclaimer into a single integrated upper travelling platform system. This unified structure distributes loads more efficiently across the supporting framework, improving stress rationality and structural integrity compared to separate supporting structures.

AI summary
An arrangement structure of a stacker and a reclaimer, comprises a stacker, a reclaimer, a stacker travelling track, a reclaimer travelling track, a material input conveyor, a material output conveyor, a material storage yard, and a closed material storage shed. The stacker and the material input conveyor are inside the reclaimer, and the reclaimer upwards straddles the stacker and the material input conveyor. The stacker and the material input conveyor penetrate through an internal space of the reclaimer. An arrangement form that a rack of the reclaimer upwards straddles the stacker is adopted so that a problem of interference caused when the stacker is as high as an upper travelling platform of the reclaimer is solved. The upper travelling platform of the reclaimer does not need to be independently arranged.
