Problems solved by technology
[0006] 1) The front outrigger and the rear outrigger move at the same time, which is prone to the problem of large overshoot
[0007] 2) It is difficult to control the lifting speed. If the lifting speed of the outrigger is too fast, the cutter head on the milling drum will impact too much on the road surface, which will damage the cutter head; if the lifting speed of the outrigger is adjusted too slowly, it will affect the leveling response speed during construction.

The invention discloses an intelligent leveling system and method for a milling machine. The intelligent leveling system is provided with a controller, an inclination sensor, a speed sensor and a rope sensor, and the inclination sensor, the rope sensor and the speed sensor are respectively connected to the controller ; The inclination sensor is used to detect the inclination angle of the frame of the milling machine in real time, the rope sensor is used to detect the distance between the side slide plate and the frame of the milling machine in real time, and the speed sensor is used to detect the distance between the frame of the milling machine According to the driving speed of the machine, the controller adopts different leveling strategies according to the detection results of the speed sensor, and performs leveling by adjusting the front outrigger and the rear outrigger in stages in the milling state. Compared with the existing technology, the intelligent leveling system can reduce the impact on the cutter head and effectively avoid the problems of large overshoot and difficulty in controlling the lifting speed. On this basis, the present invention also discloses a milling machine with the above-mentioned intelligent leveling system.
Description
Technical field [0001] The invention relates to road milling technology, in particular to a milling machine and its intelligent leveling system and method. Background technique [0002] At present, the milling machine is the main equipment of the asphalt pavement and cement pavement maintenance construction machinery; it is mainly used for the excavation and excavation of asphalt concrete and cement concrete surfaces such as expressways, first-class highways, urban roads, airports, freight yards, parking lots, etc. Renovation. The milling machine can efficiently mill away cracks, ruts, looseness, subsidence and surface function degradation of asphalt pavement and other pavement diseases; moreover, it can also efficiently mill away the arching, staggering and peeling of cement concrete pavement. Peeling, potholes, pockmarked, exposed, loose and polished diseases. The milling machine has high work efficiency, simple construction process, easy control of milling depth, convenient ...
