Problems solved by technology

At present, the general-purpose devices for swinging outriggers are implemented by rotating around a fixed axis. This way of swinging outriggers will cause a 180° change in the forward direction of the tires or crawlers connected to the outriggers. Therefore, it is necessary to increase the direction of rotation. Valves are used to switch the direction of the oil circuit to change the forward direction of the tire or track, which not only

Abstract

The invention provides a pavement milling machine and a landing leg swinging mechanism thereof. The landing leg swinging mechanism comprises a double-rocker mechanism consisting of a machine frame, swinging rods, a rotatable sleeve rod, and fixing and connecting rods, wherein the swinging rods and the rotatable sleeve rod are rockers; and the fixing and connecting rods are connecting rods, are rotatably connected with the rotatable sleeve rod by taking landing legs of the pavement milling machine as hinge shafts, and are fixedly connected with the landing legs and are parallel to each other before and after swinging of the double-rocker mechanism. According to the landing leg swinging mechanism, the double-rocker mechanism is adopted, and the landing legs are used as the hinge shafts of the rotatable sleeve rod and the fixing and connecting rods; and due to the adoption of the structure, the fixing and connecting rods are fixedly connected with the landing legs and keep parallel to each before and after swinging, so that the direction of the forward motion of a tire or a tack is not changed, and under the condition that the two kinds of rockers are small in movement range, the landing legs positioned at the hinge points are large in displacement range; and the landing leg swinging mechanism is compact in structure and small in occupied space.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a road milling machine and a leg swing mechanism thereof. Background technique [0002] Road milling machine is one of the main types of road maintenance machinery, which is widely used in urban municipal road and highway maintenance projects. When the road surface milling machine is milling the edge of the road surface, one side of the outrigger needs to be swung to the inside of the milling machine, so that the milling device can successfully complete the milling of the road edge. At present, the general-purpose devices for swinging outriggers are implemented by rotating around a fixed axis. This way of swinging outriggers will cause a 180° change in the forward direction of the tires or crawlers connected to the outriggers. Therefore, it is necessary to increase the direction of rotation. Valves are used to switch the direction of the oil circuit to change the forward dir...
