AI Technical Summary

Technical Problem

Traditional excavator connectors pose safety hazards, potentially causing attachments to detach and endangering construction site safety.

Method used

A quick connector was designed with a double-locking structure, including a first gripper lock assembly and a second gripper lock assembly. The first and second grippers are driven to move along the guide rail by a hydraulic cylinder assembly to lock or unlock the attachment shaft, ensuring that the attachment does not come off in case of failure.

Benefits of technology

In the event of a hydraulic system malfunction or connector cylinder failure in an excavator, the double safety lock can effectively prevent the attachment shaft from coming off, ensuring safety at the construction site and reducing accidents.
