Wheel Transfer Device Non-Return Mechanism Prevents Derailment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the manufacturing of automobile aluminum alloy wheels, the existing wheel transfer systems using I-shaped guide rails and driving chains are prone to derailment when the driving chain breaks, leading to safety hazards and reduced finished product ratios due to wheels falling.
Innovation Solution
A wheel transfer device with an I-shaped guide rail equipped with lifting lugs and non-return units, including non-return rotating plates and components, prevents the driving chain from moving backward, ensuring the rolling wheels remain in place even after chain breakage, and includes anti-fouling chain pieces for cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a driving chain is used to drive rolling wheels along the I-shaped guide rail, then the wheel transfer device achieves continuous motion and productivity, but when the driving chain breaks, the rolling wheels derail and wheels fall, reducing reliability and safety
Solution Approach 1:
The non-return unit is pre-installed on the I-shaped guide rail to provide preliminary protection against backward motion. When the driving chain breaks, the non-return unit's right-angle portion immediately abuts against the guide rail to prevent the rolling wheels from rolling backward, thus preventing derailment and wheel falling before the damage can occur
Solution Approach 2:
The invention converts the harmful effect of chain breakage into a beneficial locking action. When the driving chain breaks, the weight of the wheel assembly causes the non-return rotating plate to rotate and lock in place, with the right-angle portion abutting against the guide rail to create a mechanical stop that prevents catastrophic failure
2Device complexity
If the driving chain is allowed to move freely to accommodate chain breakage, then the device maintains simplicity, but the rolling wheels can reversely roll causing derailment and safety accidents
Solution Approach 1:
The non-return unit acts as an intermediary element between the driving chain and the rolling wheels. It allows the chain to move freely during normal operation but intervenes when backward motion is detected, using the right-angle portion to block the guide rail and prevent the rolling wheels from derailing
Solution Approach 2:
The non-return rotating plate provides dynamic response to chain breakage. During normal operation, it rotates freely with the chain movement. When the chain breaks, the weight-induced backward motion causes the plate to rotate and lock, with the right-angle portion abutting against the guide rail to create a dynamic safety mechanism
