Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transport equipment in mining and underground excavation lacks sufficient load-bearing capacity and stability, particularly when turning in narrow tunnels, and requires separate body structures for different load capacities.
Innovation Solution
The development of articulated transport equipment with a mobile body, center articulation, and a connectable trailer featuring steerable wheels, which allows for improved load-bearing capacity and reduced space requirements for turning, along with enhanced stability through a well-distributed center of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the load-bearing capacity of transport equipment is increased, then the equipment can remove rock material more effectively, but the space required for turning in mining tunnels increases
Solution Approach 1:
The transport equipment is divided into separate modular components: a transport equipment body and a trailer that can be connected or disconnected. This segmentation allows the main body to be compact for narrow tunnel operation, while the trailer provides additional load-bearing capacity when connected, resolving the contradiction between load capacity and turning space requirements
Solution Approach 2:
The equipment incorporates dynamic articulation mechanisms including a center articulation in the body and steerable wheels on the trailer. These dynamic elements enable the equipment to adapt its configuration during operation, allowing tight turning when needed while maintaining high load-bearing capacity when the trailer is attached, thus resolving the static contradiction between size and capacity
2Strength
If the transport equipment is designed for higher load-bearing capacity, then rock material removal efficiency improves, but the stability during turning deteriorates
Solution Approach 1:
The steerable wheels on the trailer provide dynamic stability control during turning operations. By actively steering the trailer wheels in coordination with the center articulation, the equipment maintains stable movement even when carrying heavy loads, preventing the jack-knife toppling that occurs in conventional designs
Solution Approach 2:
The center articulation acts as an intermediary mechanism between the front and rear sections of the equipment. It mediates the forces and movements during turning, distributing loads and maintaining balance, thereby preventing instability and toppling while enabling high load-bearing capacity
3Reliability
If the body structure is designed separately for differently-sized transport equipment, then each configuration can be optimized, but it becomes impossible to utilize similar body structures in transport equipment having different bearing capacities
Solution Approach 1:
The equipment is designed with segmented modular components including interchangeable trailers and a standardized transport equipment body. This modular segmentation allows different trailer configurations to be attached to the same body structure, enabling optimization for different load capacities while maintaining structure reusability across various equipment configurations
Solution Approach 2:
The transport equipment body is designed as a universal platform that can work with multiple trailer types and configurations. This universal design allows the same body structure to be used across different equipment variants with different bearing capacities, achieving both optimized performance and structure reusability
