ROAD MILLING MACHINE AND LEG SWINGING MECHANISM FOR SAME

摘要

A road milling machine and a leg swinging mechanism for same. The leg swinging mechanism comprises a dual-rocker mechanism formed of a frame (1), a swing rod (5), a rotatable sleeve rod (2), and a fixed connecting rod (4). The swing rod (5) and the rotatable sleeve rod (2) are rockers. The fixed connecting rod (4) is a connecting rod. A rotatable connection is formed between the fixed connecting rod (4) and the rotatable sleeve rod (2) with a leg (3) of the road milling machine being a hinge axis, and the fixed connecting rod (4) and the leg (3) are fixedly connected, and are parallel to each other before and after the swinging of the dual-rocker mechanism. The structure of the leg swinging mechanism does not change the travel direction of the tires or continuous tracks during the swinging of the leg (3), and with small movement ranges of the two rockers, the leg (3) located at the hinge point has a large displacement range, is compact in structure, and occupies a small space.
