Abstract

The invention discloses a paver automatic leveling control device and method, and a paver. The device includes an automatic leveling unit for detection of road surface roughness and outputting a PWM signal with pulse width corresponding to a leveling deviation signal, a main controller for performing matching processing and operation processing of the PWM signal and signals outputted by other systems, and transmitting the processed signals to a leveling electromagnetic valve, and the leveling electromagnetic valve for responding to the processed signals so as to control a leveling oil cylinder to work to realize automatic leveling, wherein the automatic leveling unit is electrically connected with the leveling electromagnetic valve through the main controller. The difficulty of matching of a paver automatic leveling system with other systems can be greatly reduced, the response time of the leveling electromagnetic valve is shortened, the stability of paving work is improved, and the flatness of a paving road surface is ensured.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an automatic leveling control device and method for a paver and a paver. Background technique [0002] With people's continuous pursuit of high speed and comfort, the requirements for highway construction quality are also increasing, especially the requirements for road surface smoothness. As the core equipment of high-grade pavement paving, asphalt paver has an important influence on the quality of pavement construction. As a key technology of paver, the automatic leveling technology of paver directly affects the smoothness of the road surface. [0003] In the prior art, since the control signal of the leveling instrument is directly output to control the electromagnetic reversing valve, without going through the main controller of the paver, it is not easy to carry out automatic leveling system and other systems such as the walking system and lifting system of th...
