Gantry Crane Rail Fixing Device for Flexible Beam Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing size of factory buildings poses a challenge for existing gantry crane systems, as the distance between supporting pillars grows, making it impractical to customize the length of longitudinal beams and the span of gantry cranes, leading to inefficiencies in using standard equipment.
Innovation Solution
The introduction of a device comprising a main body with protruded supports that can be fixed under the crossbeam of a factory building, allowing for flexible positioning of longitudinal beams and rails, enabling the use of existing equipment in larger structures by adjusting the distance between supporting bases and protruded supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the distance between supporting pillars is increased to accommodate larger factory buildings, then the building size and capacity are improved, but the distance between supporting bases and longitudinal beams increases, making it impossible to use existing standard equipment
Solution Approach 1:
The longitudinal beam is divided into multiple segments that can be independently positioned using the fixing device. Instead of requiring a single long beam to span the entire distance between pillars, the system uses multiple standard-length beams positioned at different locations along the crossbeam, allowing the building to accommodate larger spans while using existing standard equipment dimensions.
Solution Approach 2:
The fixing device acts as an intermediary component between the crossbeam and the longitudinal beam. It provides adjustable positioning capability that allows standard longitudinal beams to be placed at optimal locations along the crossbeam, enabling the system to adapt to various building sizes without requiring custom-length beams.
2Adaptability or versatility
If custom-length longitudinal beams and gantry cranes are manufactured for each building, then the equipment fits the specific building requirements perfectly, but the manufacturing cost and complexity increase significantly
Solution Approach 1:
The fixing device is designed to be universally applicable to different building configurations and sizes. By providing adjustable positioning capability, a single fixing device design can support multiple longitudinal beam arrangements, making the system adaptable to various building requirements without requiring custom-manufactured equipment for each project.
Solution Approach 2:
The fixing device incorporates adjustable and movable components that allow the longitudinal beam position to be dynamically optimized for different building layouts. This dynamic positioning capability enables the same standard equipment to be adapted to various building sizes and configurations, eliminating the need for custom manufacturing while maintaining optimal fit.
3Length of moving object
If the length of longitudinal beams is increased to span larger distances between pillars, then the equipment can cover larger building areas, but the equipment can no longer be used in standard sizes
Solution Approach 1:
The longitudinal beam system is segmented into multiple standard-length beam sections that can be positioned at different locations along the crossbeam. This segmentation allows the overall span to be extended by combining multiple standard sections rather than requiring a single custom-length beam, maintaining compatibility with standard equipment while achieving the required building coverage.
