Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foundation detection methods, such as the ballast platform counterforce apparatus, require significant resources and time due to the need for large cranes and repeated assembly/disassembly of balancing weights, leading to high costs and long operation times, even for short distances between measurement points.
Innovation Solution
A movable foundation static load test apparatus featuring a rack with a crawler traveling mechanism and a position adjusting mechanism, which includes hydraulic cylinders to efficiently position the balancing weight and facilitate travel, reducing the need for extensive assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a ballast platform counterforce apparatus is used for foundation detection, then the stress condition is close to reality and the operation is simple, but a large crane and workers are required to stack and load balancing weights, resulting in large test scale and high cost
Solution Approach 1:
The patent applies the dynamics principle by transforming the static ballast platform into a movable apparatus. The rack can be dynamically positioned at different test points through the crawler traveling mechanism, allowing the same apparatus to serve multiple locations without requiring disassembly and relocation of heavy balancing weights. This dynamic capability reduces the test scale and operational complexity while maintaining the simple operation characteristic.
2Adaptability or versatility
If balancing weights are repeatedly assembled and disassembled for each measurement point, then the apparatus can be positioned at different locations, but the operation time becomes long
Solution Approach 1:
The movable rack with crawler traveling mechanism enables dynamic repositioning between test points without requiring disassembly and reassembly of balancing weights. The entire apparatus can be moved as a single unit to different locations, significantly reducing the time lost to repeated assembly and disassembly operations while maintaining the ability to adapt to different measurement points.
Solution Approach 2:
The apparatus is pre-configured with the balancing weights already loaded on the rack. This preliminary action eliminates the need for on-site assembly and disassembly of weights at each test point, allowing the apparatus to be directly positioned and operated at different locations, thereby reducing operation time.
3Measurement precision
If a large crane is used to stack and load balancing weights, then the balancing weight can be positioned accurately, but the detection cost increases
Solution Approach 1:
The apparatus is designed to be self-sufficient with the balancing weights already integrated into the rack structure. The crawler traveling mechanism enables the apparatus to move and position itself at test points without requiring external large cranes for weight stacking and loading. This self-service capability maintains positioning accuracy while eliminating the need for expensive crane operations, thereby reducing detection costs.
