Annular Pipeline Guide Structure to Prevent Hydraulic Line Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic pipelines in segment assembling machines for shield machines are prone to winding during rotation, disrupting normal operation.
Innovation Solution
A pipeline annular self-guiding apparatus with inner and outer annular grooves and a freely rotating annular bracket, equipped with pipeline supporting rollers, which guide and fix pipelines to prevent winding by allowing one end to move while keeping the other end fixed, ensuring continuous connection to hydraulic cylinders during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hydraulic pipelines are connected to rotating hydraulic cylinders in the segment assembling machine, then the hydraulic cylinders can perform rotation operations, but the pipelines are easy to be wound with each other or on parts of the machine
Solution Approach 1:
The pipeline guidance system is divided into multiple functional segments: inner annular groove for pipeline routing, outer annular groove for structural support, and multiple pipeline supporting rollers spaced around the annulus. This segmentation allows each component to perform its specific function while collectively preventing pipeline winding during rotation.
Solution Approach 2:
The pipeline supporting rollers act as intermediaries between the rotating hydraulic cylinders and the fixed pipeline inlet. These rollers freely rotate and guide the pipelines through the annular grooves, allowing the pipelines to accommodate rotation without winding. The rollers mediate the motion transfer while maintaining pipeline integrity.
2Ease of operation
If the turntable rotates circumferentially with multiple hydraulic pipelines, then the segment snatching head can reach different positions, but the pipelines may wind on parts of the segment assembling machine
Solution Approach 1:
The pipeline arrangement transitions from a planar two-dimensional layout to a three-dimensional annular configuration. The pipelines are routed through the annular space between the inner and outer grooves, utilizing the radial dimension. This dimensional change provides additional space for pipeline management and prevents winding on machine parts during circumferential rotation.
Solution Approach 2:
The pipeline supporting rollers are designed to freely rotate, making the pipeline guidance system dynamic rather than fixed. As the turntable rotates and the hydraulic cylinders move to different positions, the rollers automatically rotate to accommodate the motion, keeping the pipelines taut and preventing them from winding on machine parts.
