Solution Overview
Problem
The conventional out-shaft lifting system for mine construction occupies large space, has a fixed and inflexible vertical lifting rope route, and lacks safety, particularly in blind shaft construction where space is limited and construction efficiency is hindered.
Innovation Solution
A vertical lifting device comprising a fixed frame with a sliding frame and stepping vehicles that alternately lower or lift weights, allowing flexible adjustment of the lifting rope route and incorporating a control mechanism, braking mechanism, and pulleys to ensure safe and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a derrick structure is used for out-shaft lifting, then the lifting system can support heavy loads and maintain stability, but it occupies large ground area and requires high space
Solution Approach 1:
The derrick structure is segmented into multiple independent supporting columns distributed around the wellhead. Each column independently supports the lifting system, eliminating the need for a large centralized derrick structure while maintaining load distribution and system stability.
Solution Approach 2:
The lifting system transitions from a ground-based derrick structure to an overhead structure suspended from the cap shaft. This dimensional change moves the support structure from the horizontal plane to the vertical plane, significantly reducing ground area occupation while maintaining lifting capacity.
2Reliability
If a derrick structure is used for out-shaft lifting, then the lifting system can maintain stable operation, but it occupies large space including ground area and vertical height
Solution Approach 1:
The derrick structure is segmented into multiple independent supporting columns distributed around the wellhead. Each column independently supports the lifting system, eliminating the need for a large centralized derrick structure while maintaining load distribution and system stability.
Solution Approach 2:
The lifting system transitions from a ground-based derrick structure to an overhead structure suspended from the cap shaft. This dimensional change moves the support structure from the horizontal plane to the vertical plane, significantly reducing ground area occupation while maintaining lifting capacity.
3Reliability
If a fixed derrick structure is built, then the lifting system can provide stable support, but the vertical route of the lifting rope cannot be flexibly adjusted
Solution Approach 1:
The lifting system incorporates movable pulleys and adjustable rope routing mechanisms that allow the vertical route of the lifting rope to be flexibly adjusted. The supporting columns remain fixed for stability, while the rope path can be dynamically reconfigured to accommodate different construction equipment and operational requirements.
Solution Approach 2:
The lifting system is designed with universal components that can accommodate multiple rope routing configurations. The same supporting columns and pulley system can serve different construction scenarios, making the system adaptable to various equipment types and operational needs while maintaining structural stability.
4Reliability
If a derrick is built in limited space such as blind shaft construction, then the lifting system can provide stable support, but it greatly obstructs the construction of construction equipment inside the shaft
Solution Approach 1:
The derrick structure is segmented into multiple independent supporting columns distributed around the wellhead. Each column independently supports the lifting system, eliminating the need for a large centralized derrick structure while maintaining load distribution and system stability.
Solution Approach 2:
The lifting system transitions from a ground-based derrick structure to an overhead structure suspended from the cap shaft. This dimensional change moves the support structure from the horizontal plane to the vertical plane, significantly reducing ground area occupation while maintaining lifting capacity.
