Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bolt connections in construction machinery are prone to operational inefficiencies and safety risks due to loose bolts, incomplete connections, and downtime, particularly when loosening or tightening multiple bolts, which can lead to accidents and equipment downtime.
Innovation Solution
A bolt connection system featuring a protective receptacle to securely store and align the bearing pin, a stepped bolt design to prevent pin displacement, a position securing device for radial fixation, and an actuator with hydraulic assistance to manage the bearing pin's position, along with position sensors for ensuring proper alignment and connection completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a loose bearing bolt is used for bolt connections, then the bolt connection can be easily assembled and disassembled, but the bolt may fall out or be lost during operation
Solution Approach 1:
A protective receptacle is introduced as an intermediary component to hold the bearing bolt when not in use. The receptacle is attached to the first component and provides a secure storage location for the bolt, preventing it from falling out or being lost during operation, while still allowing easy access for assembly and disassembly operations
2Reliability
If multiple bolts are loosened or tightened individually, then each bolt connection can be securely established, but significant downtime occurs for construction machinery
Solution Approach 1:
Multiple bearing bolts are combined into a single integrated assembly that moves together as one unit. The protective receptacle holds multiple bolts in a coordinated manner, allowing them to be installed or removed simultaneously rather than individually, significantly reducing the time required for bolt connection operations while maintaining secure connections
3Ease of operation
If bearing bolts are stored loosely without protection, then access is simple, but damage or contamination may occur that impedes operation
Solution Approach 1:
The protective receptacle serves as a protective intermediary between the bearing bolts and the external environment. It shields the bolts from damage and contamination while maintaining organized accessibility, ensuring that bolts remain in good operational condition when not in use
4Device complexity
If bearing bolts are not securely positioned, then the structure is simpler, but the bolts may detach or fail to establish complete connection
Solution Approach 1:
The protective receptacle acts as a positioning intermediary that guides and secures the bearing bolts in the correct positions. It includes features such as guide channels and positioning elements that ensure bolts are properly aligned and seated, guaranteeing complete and reliable connections without requiring complex external positioning mechanisms

AI summary
The invention relates to a bolt connection with a bearing bolt, in particular for a construction machine, in particular for civil engineering, and for a pivoting lever, in particular for a construction machine, which pivotably connects a first component and a second component to one another, the bearing bolt being attached to the first component and at least one second bearing eye on the second component, and wherein the bearing bolt can be driven out of the first bearing eye and the second bearing eye to release the connection to an exit side. A protective receptacle is arranged on the exit side, which is designed to receive and store the driven-out bearing bolt.
