The present invention discloses a control method, control equipment and a control system of a milling-planing machine, and the milling-planing machine. The milling-planing machine comprises a machine body, a lifting support leg, a lifting swing support leg and a milling-planing drum. The control method comprises that the vertical distance between a first position and a reference portion is received when the lifting swing support leg contracts and is recorded as the first vertical distance, wherein the first position is the position on the machine body, the lifting support leg or the lifting swing support leg, and the vertical distance between the first position and the reference portion can be reduced along with the contraction of the lifting swing support leg; and the first vertical distance and a first predetermined distance are compared, and the contraction of the lifting swing support leg is controlled to be stopped when the first vertical distance is equal to the first predetermined distance, wherein the first predetermined distance is the vertical distance between the first position and the reference portion when the lifting swing support leg contracts in the place after the milling-planing drum contacts the ground. With the control system of the milling-planing machine of the present invention, the distance measurement device and the control equipment are additionally arranged on the original milling-planing machine so as to effectively determine when the lifting swing support leg contracts in the place.
Description
technical field [0001] The present invention relates to road maintenance equipment, in particular to a milling machine control method, control equipment, control system and milling machine. Background technique [0002] The milling machine is an efficient road surface maintenance equipment, and the performance of the equipment directly affects the quality of the road surface milling work. [0003] Now take the small milling machine as an example to introduce the milling machine in the prior art. The characteristic of the small milling machine is that one side of the leg (that is, the lifting and swinging leg mentioned below) can swing to the inside to realize the edge milling of the road surface. Specifically, the small milling machine includes a car body, a milling drum, two There are two front outriggers and two rear outriggers (namely lifting outriggers and lifting swing outriggers), wherein the milling drum is installed at the rear of the vehicle body and is located bet...
