Description

technical field [0001] The invention relates to the technical field of a road cutting machine, in particular to a hydraulically controlled self-advancing road cutting machine. Background technique [0002] The pavement cutting machine is widely used in the cutting of new pavement expansion joints in highway construction and municipal engineering, as well as the maintenance and grooving of old pavement. The road cutting machine is mainly composed of an engine, a traveling device and a cutting device. When working, it mainly drives the diamond saw blade to rotate along the cutting line and advances to complete the cutting operation. Existing pavement cutting machines, except for a very small number of fully automatic products, mostly use manual hand pushing, and only a few products are equipped with hand-operated power-assisted walking devices. The device is designed with power-assisted propulsion to rotate the hand wheel. The rotation of the hand wheel drives a worm shaft th...

Problems solved by technology

The walking of the domestic small road cutting machine is mainly carried out manually. Due to the great travel resistance during cutting, the labor intensity of the workers is high, the working environment is poor, and stable cutting cannot be guaranteed. At the same time, there are also large and small feed forces, which are not easy to stabilize Control and other issues, which affect the quality of cutting work and work efficiency

[0003] With the rapid development of expressway construction in our country, there is an urgent need for a road cutting machine with a large depth of cut in expressway maintenance. The depth of cut is required to be above 250mm. It is very difficult to implement this depth of cut manually.
