Paver longitudinal slope automatic leveling control device and method and paver

Abstract

The invention relates to a paver longitudinal slope automatic leveling control device and method and a paver. The paver longitudinal slope automatic leveling control device comprises a leveling control part and a leveling detection part, at least one of the leveling control part, the leveling detection part and a whole paver control part is provided with a setting unit, and the leveling control part is used for selecting the working mode controlling a leveling execution mechanism according to road paving grade requirements, and the working mode comprises the steps that the leveling detection part is matched with the leveling control part to achieve independent leveling and is matched with the whole paver control part to achieve on-line leveling, and the leveling detection part is used fordetecting the height deviation between the paver and leveling reference to make the control device achieve leveling in the selected working mode. The paver longitudinal slope automatic leveling control device can flexibly select the appropriate working mode according to the road paving requirements, on occasions with low paving requirements, the road paving efficiency is improved, and the cost issaved; on occasions with high paving requirements, whole paver closed-loop control is achieved, and the road paving precision is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a paver vertical slope automatic leveling control device, method and paver. Background technique [0002] With the development of basic road paving construction, the relevant departments of road inspection and acceptance put forward higher requirements for the construction technology and acceptance indicators of the road, and the requirements for the compactness, uniformity, and flatness of the road surface are getting higher and higher. And the biggest influence on the pavement quality is the automatic leveling device of the paver. [0003] In the solution of the prior art, after the paver works, the leveling control device independently completes the leveling work, and the rotating input device at the outer end of the rotating shaft drives the rotating shaft to rotate, so that the angular displacement sensor can continuously detect the distance between the asphalt...

AI Technical Summary

Problems solved by technology

[0004] At present, the leveling control device is independent of the control system of the whole machine. Due to the independence of the leveling control work, when it works with other systems of the host computer, some error states cannot be judged in time, and it cannot be related to factors such as the operating speed of the host computer. Especially in terms of sensitivity and reliability There are many defects and deficiencies in the synergy of the whole machine, which is greatly restricted in application, which leads to poor construction stability and smooth road surface of the paver using the automatic leveling device of the paver in the prior art. Poor degree, poor system compatibility and other issues

[0005] Moreover, the leveling control device and the whole machine control device need to be operated and controlled by independent workers on site, and the linkage operation is only realized manually, with a low degree of automation and poor control effect

The whole process is an independent open-loop, relying on the characteristics of the paving screed to erase small deviations. In addition, the low-automation paving operation will lead to untimely handling of special working conditions in the leveling process, which is far from meeting the current requirements for paver.
