Carriage Assembly Insertion Mechanism for Construction Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing carriage arrangements for construction machines are time-consuming and pose occupational safety risks due to the need for manual alignment and climbing to form connections, especially when dealing with heavy rotary drives or vibrator units.
Innovation Solution
A carriage arrangement where the carriage insert is pushed into the device carriage from below, allowing ground-level observation and connection, using insertion links and bolts with an axial stop and flattened contact sections for precise alignment and secure fixing, and a locking bolt system for reliable attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual alignment and climbing are used to form connections, then secure attachment is achieved, but occupational safety risks and time consumption increase
Solution Approach 1:
The patent inverts the traditional connection approach by enabling insertion from below instead of from above. The carriage insert with insertion bolts is inserted upward into the device carriage through insertion tracks, allowing ground-level operation while maintaining secure attachment. This inversion eliminates the need for workers to climb ladders, thereby removing occupational safety risks while preserving connection reliability.
2Reliability
If precise alignment is performed manually, then reliable connection is achieved, but time and labor requirements increase
Solution Approach 1:
The patent introduces insertion tracks as intermediary guiding structures that automatically align the insertion bolts with the device carriage. These tracks act as mediators between the carriage insert and device carriage, providing mechanical guidance that ensures precise alignment during the insertion process. This eliminates the need for time-consuming manual alignment operations while maintaining reliable connection through the guided insertion mechanism.
3Ease of manufacture
If insertion from above is used, then connection is formed, but ground-level observation and control become difficult
Solution Approach 1:
The patent inverts the insertion direction so that the carriage insert is inserted from below upward into the device carriage. This allows workers to observe and control the entire insertion process from ground level without needing to climb to elevated positions. The insertion tracks guide the bolts upward, maintaining connection formation capability while dramatically improving ease of operation and ground-level visibility.
