Milling machine

Abstract

The invention relates to a milling machine, and belongs to the technical field of mechanical equipment special for roads. The milling machine comprises a frame, a seat rotationally and adjustably connected with the frame, handrails rotationally and adjustably connected with the frame and a crawling ladder rotationally, adjustably and elastically connected with the frame; and the handrails and thecrawling ladder are arranged at the outer side of the frame, the handrails can be rotationally stored inwards, the crawling ladder can be rotationally extended downwards, and the crawling ladder can be rotationally folded upwards to be stored. According to the milling machine, the handrails, the crawling ladder and the seat can be inwards contracted, and the requirements for welt milling and the whole machine transportation width can be met after contraction, so that the construction is facilitated, and the transportation is safer.

Description

technical field [0001] The invention relates to a milling machine, which belongs to the technical field of road special machinery equipment. Background technique [0002] Road milling machine is a special mechanical equipment for highway and urban road maintenance. It is mainly used for excavation and renovation of asphalt concrete surface layers such as highways, airports, docks, parking lots, etc., asphalt pavement rutting, cracks, carbuncles, road markings, etc. Removal of road surface diseases, roughening of cement pavement and milling of staggered surface layers; large milling machines need to see the front crawler and the side plate of the milling room due to the requirements of the field of view during construction work, and the right handrail ladder pedal seat The chairs need to protrude from the outside of the frame. At present, the handrails and ladders on the right are fixed on the frame. The whole machine is super wide during edge milling or long-distance transpo...
