Conveying Unit for Laying Electric Lines in Stator Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laying vehicles for magnetic levitation railways face challenges in maintaining constant spacings between undulation limbs during transfer from the bending and offset unit to the pressing station, leading to inefficiencies and the need for manual intervention, which limits laying speed and reliability.
Innovation Solution
A conveying unit with an endless conveyor belt is introduced to maintain constant intervals between undulation limbs, ensuring precise transfer to the pressing station, even when multiple pressing elements are used, by using take-up pockets and a guiding system that compensates for variations in distance caused by moving vehicle parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If circulating transport ropes or mounting carriages moving to and fro are provided on the laying vehicle, then the undulations can be transported from the bending and offset unit to the pressing station, but the distances of the undulation limbs to be inserted into the grooves fail to remain exactly constant
Solution Approach 1:
The patent introduces a conveying unit with a conveyor belt as an intermediary mechanism between the bending/offset unit and the pressing station. This conveyor belt specifically designed for transporting undulations maintains constant spacing through its structured design with recesses that hold individual undulation limbs at fixed intervals, thereby resolving the spacing inconsistency problem caused by movable mounting carriages or transport ropes.
Solution Approach 2:
The patent replaces the problematic mechanical systems (circulating transport ropes or mounting carriages moving to and fro) with a more stable conveyor belt system. The conveyor belt provides a rigid, controlled transport mechanism that maintains constant undulation limb spacing through its fixed recesses, substituting the flexible but imprecise rope/chute system with a more precise mechanical conveyance system.
2Manufacturing precision
If plates or other fixing means serving as spacers are utilized, then the undulation limbs are laid at correct positions, but these fixing means must be manually removed and additional manual labor is required
Solution Approach 1:
The conveying unit's conveyor belt is designed with recesses that automatically hold and position undulation limbs at correct intervals during transport. The system serves itself by maintaining proper spacing through the inherent structure of the conveyor belt rather than requiring external fixing means that need manual removal. The undulations are transferred automatically with correct positioning built into the conveyor design.
Solution Approach 2:
The patent extracts the positioning function from separate removable plates or fixing means and integrates it directly into the conveyor belt structure. The recesses in the conveyor belt inherently provide the spacing function that previously required separate fixing elements, eliminating the need for manual installation and removal of spacers.
3Manufacturing precision
If only one undulation limb at a time is pressed into the groove, then the pressing operation can be performed accurately, but the laying speed is limited
Solution Approach 1:
The patent segments the pressing operation by providing multiple pressing elements (first pressing element and second pressing element) that can simultaneously press different undulation limbs into different grooves. This segmentation allows parallel processing of multiple undulations, increasing laying speed while maintaining the accuracy of individual pressing operations through dedicated pressing elements for each groove.
Solution Approach 2:
The conveying unit enables continuous transport of multiple undulation limbs to the pressing station, where multiple pressing elements simultaneously perform pressing operations. This creates a continuous workflow where undulations are constantly being transported and pressed without interruption, eliminating the idle time between sequential pressing operations and thereby increasing overall laying speed.

AI summary
The invention relates to a laying vehicle for laying electric lines (8) in the grooves (6) of an inductor (4), for example a longitudinal stator of a maglev railway. The laying vehicle contains a first, preceding vehicle part (11) comprising a bending and offset unit (14) for configuring winding undulations, a second following vehicle part (16) comprising a pressing station (18) for pressing limbs (8a) of the undulations into the grooves (6), the second vehicle part (16) being displaceable in relation to the first vehicle part (11) and a slide (15) that is coupled in a driven manner to the first vehicle part (11), for transferring the undulations to the second vehicle part (16). According to the invention, a delivery unit (27), which is coupled to the second vehicle part (16), is located between the slide (15) and the pressing station (18), said unit receiving the limbs (8a) from the slide (15) and transferring them to the pressing station (18) at essentially constant intervals.
