Technical Field
The invention belongs to the technical field of pavers, and particularly relates to a paver with an automatic camber distance fitting system and an application method thereof.
Background
The paver is a special machine for paving road building materials such as asphalt mixture, base layer stabilizing material, roller compacted concrete material, graded broken stone and the like, and is one of key devices for building base layers and surface layers of various grades of highways and municipal roads, squares, airports and parking lots. The paver paves and shapes the material according to the requirements of width, thickness, camber, wherein the camber of the road surface means the height difference of the position near the center of the road surface relative to the edge positions of two sides of the road surface, and the general shaped road surface is a positive camber formed by high middle and low two sides, thus being beneficial to draining water and avoiding water accumulation on the road surface. When multi-curve roads such as mountainous areas, residential areas and the like are paved, the camber of the road surface changes very frequently, so that the screed plate device on the paver is required to adjust the camber in time to adapt to the requirements of road surface parameters.
The screed plate device of the paver is usually connected with the left section and the right section by adopting a middle hinge structure so as to realize camber adjustment. In the past, the camber is adjusted manually by using a wrench, the adjusting process is time-consuming and labor-consuming, the adjusting effect always lags behind the current actual camber requirement, and the camber adjusting precision is not high. Under the working condition that the camber of the pavement is required to change frequently, inconvenience is brought to a construction site, even the adjustment is carried out by suspending the construction, and the construction efficiency and the pavement forming quality are seriously influenced.
