Track Bogie King Pin Switching for Towable Mobile Conveyors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile conveyor systems face challenges in easy transportation between distant work sites, as securing them onto trailers is difficult and costly.
Innovation Solution
A conveyor system with a track bogie and pivotal king pin, allowing the conveyor to be easily raised and lowered for operation on-site and towing between sites, respectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile conveyor is mounted onto a trailer for transport between sites, then the conveyor can be towed to distant work sites, but securing the conveyor onto the trailer is difficult and requires additional expensive equipment
Solution Approach 1:
The king pin is integrated directly into the bogie structure, merging the towing function with the mobility system. This eliminates the need for separate trailer mounting equipment and simplifies the securing process while maintaining the ability to transport the conveyor between distant work sites
2Adaptability or versatility
If the mobile conveyor is mounted onto a trailer for transport, then the conveyor can be moved between sites, but additional expensive equipment is required
Solution Approach 1:
By combining the towing function into the existing bogie structure through the integrated king pin, the invention eliminates the need for separate expensive trailer equipment, reducing overall equipment costs while maintaining transport capability
Solution Approach 2:
The king pin serves multiple functions: it enables towing between sites, allows for easy attachment/detachment, and integrates with the bogie structure. This multi-functionality replaces the need for dedicated trailer equipment, reducing overall system cost
3Ease of operation
If the king pin is in the raised position, then the continuous tracks can operate on the ground surface, but the conveyor cannot be towed
Solution Approach 1:
The king pin is designed to be dynamically positionable between raised and lowered states. This dynamic positioning allows the system to adapt between track operation mode (raised) and towing mode (lowered), resolving the contradiction between operational capability and transport capability
4Adaptability or versatility
If the king pin is in the lowered tow position, then the conveyor can be connected with a tow vehicle, but the continuous tracks cannot operate on the ground surface
Solution Approach 1:
The dynamic positioning mechanism allows the king pin to be lowered for towing operations and raised for track operations. This dynamic adjustment resolves the contradiction by enabling the system to switch between towing mode (king pin lowered) and operational mode (king pin raised)

AI summary
This disclosure provides a conveyor system having a track bogie with a pair of continuous tracks. A conveyor chassis is rotatably connected with the track bogie. A pivotal king pin is positioned between the continuous tracks and operable for pivoting between a raised position and a lowered tow position, the raised position allowing for operation of the continuous tracks on a ground surface and the lowered tow position allowing for connection with a tow vehicle.
