Lifting Column Locking Element for Construction Machine Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction machines for working ground pavements require cumbersome and inconvenient securing mechanisms during maintenance to prevent accidental dropping, which complicates the process and increases the need for simplification.
Innovation Solution
A locking element is inserted into a mount on the column element of the lifting column, limiting movement and preventing accidental drops, with a securing mechanism like an O-ring to prevent slipping, and a storage container system ensuring the machine can only be operated when the locking element is securely stored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simple supports are clamped tight between the travelling device and the machine frame to prevent dropping during maintenance, then the construction machine can be secured against inadvertent dropping, but the securing means become cumbersome and inconvenient to handle
Solution Approach 1:
The invention extracts the essential securing function from the complex support system and concentrates it into a single locking element that can be easily inserted into a mount on the column element. This locking element projects at least in part vis-à-vis the column element to limit relative movement between the column element and guiding element, providing the necessary security while being simple to handle.
Solution Approach 2:
The locking element acts as an intermediary component between the column element and the guiding element. It is inserted into a mount on the column element and projects outward to engage with the guiding element, thereby mediating the securing function without requiring complex support structures clamped between the travelling device and machine frame.
2Reliability
If multiple locking elements are used to secure different parts of the lifting column, then comprehensive security is achieved, but the number of components to be carried and managed increases
Solution Approach 1:
The invention creates a universal locking element that can be used at multiple positions along the lifting column. The locking element has a standardized design with a securing element that can engage with corresponding mounts at different heights, allowing a single type of locking element to provide comprehensive security throughout the lifting column without requiring multiple different components.
Solution Approach 2:
The lifting column is divided into multiple segments with individual mounts at different positions, each capable of receiving a locking element. This segmentation allows the column to be secured at specific points as needed, providing comprehensive security while maintaining the ability to use identical standardized locking elements at each segment.
