Opening structure of side plate of milling machine, side plate and milling machine

Abstract

The invention provides an opening structure of a side plate of a milling machine, the side plate and the milling machine. The opening structure comprises a rotating part used for making the side plateof the milling machine rotate relative to a milling drum, and a sliding part, wherein a part of the rotating part is arranged in the sliding part so that the side plate can horizontally move in the axis direction of a bearing support and get away from or close to the milling drum; the sliding part is of sufficient length, so that in the process that the side plate rotates relative to the millingdrum, a supporting flange and the bearing support are not in contact with each other all the time, and the possibility of interference is reduced. According to the opening structure, a combined structure capable of making the side plate rotate after translation is adopted, in the opening process of the side plate, the supporting flange and the bearing support are separated, interference during opening and closing is reduced, the structure is simple, and the operation is convenient. The structure of the milling machine does not need to be greatly improved, so that the cost is low. Compared withthe prior art, when the milling drum is replaced, people do not need to disassemble the whole side plate, and therefore time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of road surface engineering equipment, in particular to an opening structure of a side plate of a milling machine, a side plate and a milling machine. Background technique [0002] With the continuous development of milling machines, there is a higher demand for the replacement efficiency of the milling drum. The current drum replacement method needs to disassemble the transmission door box, reducer and other components, and then remove the milling drum from the bearing support end. The milling drum is withdrawn. [0003] Since the milling drum needs to be pulled out from the bearing support end, the side plate needs to be designed as a structure that can be opened and closed. At present, the mainstream side plate opening and closing methods mainly include the following two types: [0004] The first method: single hinge + screw fixing, since opening the side plate directly will cause interference between th...

Problems solved by technology

[0004] The first method: single hinge + screw fixing, since opening the side plate directly will cause interference between the support flange and the bearing support, it is necessary to remove the fixing screws of the side plate and the screws on the support flange, and then take out the support flange. Only at this time can the side plate be opened, and because of the cover of the side slide plate, the process of removing the screws on the support flange is very difficult, and sometimes it is even necessary to remove the side slide plate before removing the support flange, which requires a lot of work and takes a long time , unable to change drums quickly
