Cageway Connecting Device for Mining Hoist Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional cageway connection method in mining equipment is prone to installation accuracy issues, deformation, maintenance difficulties, and replacement challenges due to limited adjustment capabilities and direct force transfer between cageways, which affects the straightness, smoothness, and flatness required for high-speed and heavy-load lifting systems.
Innovation Solution
A cageway connecting device featuring a notch at the top end of the lower cageway, with a connecting cageway, upper and lower cannulas, first steel angles, a fixed block, pin boss, and a fixed pin, allowing for adjustable and stable connection between cageways, and an assist mechanism with second steel angles and backing boards to enhance stability and prevent offset.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If direct butt joint is used to connect upper and lower cageways, then mutual interference between cageways is reduced, but dislocation between cageways occurs which is harmful to overall quality
Solution Approach 1:
The patent introduces a connecting cageway as an intermediary component between the upper and lower cageways. This connecting cageway includes positioning cannulas that fit into corresponding cannulas on the upper and lower cageways, creating a precise intermediary connection mechanism that eliminates direct butt joint dislocation while reducing mutual interference.
2Strength
If positioning cannula is welded at the end of cageway and directly inserted into another cageway, then connection strength is improved, but uncontrollable force transfer causes deformation of lower cageway beam and cageways
Solution Approach 1:
The patent segments the connection system into multiple independent components: the connecting cageway with positioning cannulas, the upper cageway, and the lower cageway. This segmentation allows each component to bear forces independently rather than transferring uncontrollable forces directly, preventing deformation while maintaining connection strength.
Solution Approach 2:
The connecting cageway acts as a force-distributing intermediary between upper and lower cageways. The positioning cannulas and corresponding cannulas create multiple contact points that distribute forces evenly, preventing the uncontrollable force transfer that causes deformation in direct welded connections.
3Area of stationary object
If multiple cageways are fixed on one cageway beam, then space utilization is improved, but position of each cageway cannot be adjusted and installation accuracy is reduced
Solution Approach 1:
The patent makes the connection system dynamic and adjustable through the connecting cageway design. The positioning cannulas and corresponding cannulas allow each cageway to be independently positioned and adjusted on the cageway beam, maintaining installation accuracy while enabling flexible spatial arrangement.
4Device complexity
If traditional connection structure is used, then structure simplicity is maintained, but maintenance and adjustment of cageway becomes difficult
Solution Approach 1:
The patent segments the connection system into modular components (connecting cageway, positioning cannulas, upper and lower cageways) that can be independently maintained and adjusted. This modular segmentation simplifies maintenance operations while keeping the overall structure relatively simple.
