Integral Lifting Structure Over Obstacles Using Hydraulic Push Kits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction methods for lifting structures integrally over obstacles in a vertical direction with different horizontal projections pose safety hazards, compromise construction quality, and prolong construction periods due to high-altitude working conditions and challenging environmental conditions for welding.
Innovation Solution
A construction apparatus comprising parallel platform beams with slide rails, lifting beams, and hydraulic push instrument kits, along with baffles and a rotatable support, allows for controlled and stable lifting and positioning of structures over obstacles by adjusting the height and horizontal projection using hydraulic lifters and push instrument kits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If assembly in bulk in high altitude is adopted to lift structure over obstacles, then the structure can be positioned over obstacles, but safety hazards increase and construction quality deteriorates
Solution Approach 1:
The invention changes the working dimension from high-altitude assembly to ground-level operation. The lifting device is assembled and operated on the ground, then the entire structure is lifted vertically as a complete unit. This dimensional change eliminates the safety hazards and quality issues associated with high-altitude welding and assembly operations.
Solution Approach 2:
The structure is completely assembled and prepared on the ground before lifting. All welding, positioning, and preparation work are completed at ground level where safety conditions are good, rather than attempting to assemble portions of the structure while elevated over obstacles.
2Adaptability or versatility
If assembly in bulk in high altitude is adopted, then structure positioning is achieved, but construction period increases
Solution Approach 1:
By completing all assembly work on the ground before lifting, the invention eliminates the need for time-consuming high-altitude assembly operations. The structure is fully prepared in advance, and the lifting operation itself is rapid compared to traditional incremental assembly at height.
Solution Approach 2:
The ground-based assembly allows for continuous, uninterrupted work without the interruptions and safety pauses required during high-altitude operations. The entire structure can be assembled and then lifted in one continuous process, improving overall construction efficiency.
3Ease of manufacture
If traditional high-altitude working methods are used, then structure installation is completed, but labor intensity remains high and construction mode is backward
Solution Approach 1:
The invention replaces manual high-altitude assembly operations with a mechanical lifting system. A hydraulic or mechanical lifting device is used to raise the complete structure, substituting for the labor-intensive process of assembling and positioning components while workers are elevated.
Solution Approach 2:
The invention transitions from vertical high-altitude assembly to horizontal ground-based assembly followed by vertical lifting. This allows modern, efficient ground-level construction methods to be used, improving productivity and moving away from backward labor-intensive high-altitude practices.

AI summary
A construction apparatus and method for lifting structure integrally over obstacles in vertical direction to a position with different horizontal projection. The apparatus has two platform beams placed each other in parallel, two lifting beams laterally relative to the platform beams and a lifter equipped with the lifting beams. Push instrument kits are installed on the platform beams and the lifting beams respectively, and a plurality of sets of baffles installed on both sides of the platform beams to provide the push instrument kits with a counter-force when the push instrument kits work. When the structure encounters obstacles during the process of lifting the structure by two lifters, the posture of the structure can be altered by operating the push instrument kits and the lifters, such that the horizontal projection of the structure will be reduced and the structure can therefore be lifted over the obstacle in vertical direction.
