A road milling machine hydraulically assisted outrigger overturning mechanism and its overturning method

Abstract

The invention relates to a hydraulic power assisted supporting leg overturning mechanism of a road surface milling machine. The mechanism comprises a vertically-arranged supporting leg, wherein the supporting leg is transversely horizontally connected with a supporting leg overturning arm (1); one end of the supporting leg overturning arm (1) is hinged to a frame of the milling machine and the other end of the supporting leg overturning arm (1) is hinged with piston rods of an assisting oil cylinder I (2) and an assisting oil cylinder II (3) which are horizontally arranged; and cylinder barrels of the assisting oil cylinder I (2) and the assisting oil cylinder II (3) are hinged to the frame of the milling machine, and the assisting oil cylinder I (2) and the assisting oil cylinder II (3) are located on the two sides of the supporting leg overturning arm (1). The hydraulic supporting leg overturning mechanism of the road surface milling machine, provided by the invention, is simple in structure, convenient to operate and high in efficiency.

Description

technical field [0001] The invention relates to an outrigger overturning mechanism and a overturning method thereof, in particular to an outrigger overturning mechanism and a overturning method applied to a road milling machine and using hydraulic pressure to provide overturning power, and belongs to the technical field of milling machines. Background technique [0002] Road surface milling machine is one of the main types of road maintenance machinery, widely used in urban municipal roads and highway maintenance projects; when road surface milling machine is milling the edge of the road surface, it needs to swing one side of the leg to the milling machine The inner side, so that the milling device can smoothly complete the milling of the roadside. [0003] At present, when swinging the outriggers, the industry generally adopts the method of manually pushing the outriggers to rotate them around a fixed rotation axis, so that they can be flipped from the outside of the fusela...

AI Technical Summary

Problems solved by technology

With this method, generally two people are needed to push the outrigger, and another person is needed to assist in positioning (inserting the fixing pin), and the operation is time-consuming and laborious;

[0004] For this reason, Chinese patent ZL201020531369.2 has developed a "Road Milling Machine Lifting Leg Overturning Mechanism", which utilizes a swing arm to form a four-bar linkage mechanism, thereby realizing the lifting and turning of the supporting legs. Although it is convenient for workers to operate, It still has not solved the power problem, and it still needs human intervention in the swing process, so there is an urgent need for a road milling machine leg turning mechanism with simple structure, convenient operation and high efficiency.
