AI Technical Summary
The existing switchgear device causes the swing track to twist and deform at the turning points of the underground roadway due to changes in centrifugal force and gravity, and lacks an effective positioning structure, which affects the locomotive's passing efficiency.
The system employs limiting and supporting components, including limiting cylinders, limiting pins, limiting columns, rollers, and arc plates, to achieve stable limiting and support of the swing track through hinges and cylinder drive, ensuring track alignment and stable rotation.
It effectively prevents the swaying track from twisting and deforming during locomotive turning, improving the stability and efficiency of locomotive passage and reducing the need for manual correction.
