3D Laser Scanner for Crane Rail Alignment Survey
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for surveying overhead crane runway rail alignment are time-consuming, require crane downtime, and involve manual access, leading to inefficiencies and increased costs, as they struggle to accurately measure and align crane components without disrupting operations.
Innovation Solution
A non-contact rail survey system utilizing a 3D laser scanner mounted on a support base, which remains stationary to collect data on crane runway beams and rails, converting point clouds into triangulated irregular networks and voxel data structures for precise alignment analysis, allowing for remote measurement and minimal downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual surveying methods are used to measure crane rail alignment, then measurement precision can be achieved, but the survey process becomes time-consuming and requires crane downtime
Solution Approach 1:
The patent replaces traditional mechanical surveying instruments (transits, tape measures, levels) with a 3D laser scanning system. The laser scanner emits laser beams to capture spatial coordinates of rail points, converting physical measurements into digital data automatically, thereby eliminating manual operations and crane downtime while maintaining high measurement precision
Solution Approach 2:
The patent changes the measurement parameters from traditional 2D coordinates to comprehensive 3D spatial coordinates (x, y, z). This enables simultaneous measurement of multiple alignment parameters including horizontal position, vertical elevation, and rail profile geometry, achieving precise alignment assessment in a single scanning operation without requiring multiple separate measurements
2Loss of information
If manual access to crane components is required for surveying, then detailed measurement data can be collected, but operational efficiency decreases and safety risks increase
Solution Approach 1:
The patent creates a digital copy (3D point cloud model) of the physical crane rail system. The laser scanner captures complete spatial information of rails, beams, and support structures, generating a comprehensive digital replica that can be analyzed without physical access, thus preserving all necessary survey data while eliminating the need for personnel to access crane components
Solution Approach 2:
The 3D laser scanning system serves multiple functions simultaneously: it measures rail alignment, captures beam geometry, records support column positions, and generates as-built documentation. This multi-functional capability collects comprehensive survey data from a single remote operation, eliminating the need for separate manual measurement tasks and improving operational efficiency
