Description

Technical Field

[0001] The utility model relates to mechanical manufacturing and processing technology, and more specifically, to a short-rail multi-task surface processing device. Background Art

[0002] To meet the requirements of berthing, cabin change, and relocation for large container ships, the front and rear beams of the quay crane are connected by a hinge point, allowing the front beam to be raised. When the trolley passes through this hinge point on the track (short track), it will generate certain impacts and vibrations. In contrast, the non-hinge section of the trolley track is in better working condition. Since trolley track repair and maintenance work is mainly concentrated on the hinge short track, a well-made short track can ensure operational safety while reducing potential maintenance costs.

[0003] Machining can improve the quality of the trolley track. Milling the trolley track involves nine machining surfaces, making the use of a machining center costly and inefficient. Using CNC or conventional machine tools requires multiple clamping steps, which, due to the short trolley track's shape, can be time-consuming and involve high-risk lifting operations.
