Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and disassembly of full-face machines, used for underground rock excavation, are time-consuming and limited to straight-line mining due to their complex nature and large size, making them inflexible for use in confined or curved mining routes.
Innovation Solution
A transport vehicle with a chassis and receiving frame designed to accommodate longitudinal modules of full-face machines, allowing for efficient transportation and handling in cramped spaces, featuring a U-shaped chassis with crawler tracks and a detachable receiving frame that can be inserted and removed axially, enabling modular assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If full-face machines are used for underground rock excavation, then high excavation speed and efficient construction can be achieved, but the machines are too large and complex for flexible use in confined or curved mining routes
Solution Approach 1:
The full-face machine is divided into multiple longitudinal modules that can be detached and transported separately. Each module can be handled independently by the transport vehicle, allowing the machine to be disassembled for navigation through confined spaces and reassembled at the destination to maintain high excavation productivity.
2Productivity
If full-face machines are designed as large integrated systems, then high excavation efficiency is achieved, but assembly and disassembly become time-consuming and complex
Solution Approach 1:
The machine is segmented into standardized longitudinal modules with detachable connections, enabling rapid assembly and disassembly operations compared to traditional integrated designs.
Solution Approach 2:
The modules are designed with pre-configured connection interfaces and attachment points that facilitate quick coupling and decoupling operations, reducing the time required for assembly and disassembly while maintaining the integrity of the complete machine system.
3Ease of operation
If traditional transport methods are used for large full-face machines, then the machines can be moved, but they cannot be efficiently transported and handled in cramped underground conditions
Solution Approach 1:
By dividing the full-face machine into longitudinal modules, each module becomes compact enough to be handled by the transport vehicle in confined underground environments, while the complete machine can be reassembled when space permits.
Solution Approach 2:
The transport vehicle utilizes vertical space by positioning the receiving frame between its traveling vessels, allowing modules to be loaded and transported in a compact configuration that fits within the limited horizontal clearance of underground mining areas.
4Adaptability or versatility
If full-face machines are designed as modular longitudinal modules, then flexible transport and reconfiguration are enabled, but the device complexity increases
Solution Approach 1:
The receiving frame is designed as a universal component that can accommodate different longitudinal modules through standardized interfaces. This universal design allows the same receiving frame structure to handle various module types, reducing overall system complexity despite the modular configuration.
Solution Approach 2:
The receiving frame acts as an intermediary device between the transport vehicle and the longitudinal modules. It provides a standardized interface that simplifies the interaction between the vehicle and diverse modules, managing the complexity of modular operations through a single mediating component.
