Problems solved by technology

But because the distance between the two brackets is too long, the iron wire in the middle between the two brackets may sag due to gravity, which will cause the road surface paved by the paver to be uneven.

Abstract

The invention provides an automatic leveling paver ironing structure with a heating function. The automatic leveling paver ironing structure comprises an ironing plate main body, a left-side oil cylinder, a right-side oil cylinder, a middle oil cylinder, a heating device and leveling devices. The left side of the ironing plate main body is connected with the left-side oil cylinder through a left force applying component. The right side of the ironing plate main body is connected with the right-side oil cylinder through a right force applying component. The middle of the ironing plate main body is connected with the middle oil cylinder through a force applying component. The heating device is arranged on the outer side of the ironing plate main body. The leveling devices are arranged on the two sides of the ironing plate main body correspondingly. The tortuosity and the temperature of the ironing plate main body are controlled in real time, and thus the road surface paving operation quality is effectively improved; and in the paving process, the effect that an ironing plate operates on the same horizontal plane is ensured, so that the situation that a paved middle road surface is thinner than road surfaces at the two ends due to too long distance between iron wires and the effect of gravity is effectively avoided.

Description

technical field [0001] The invention relates to the field of road surface operation machinery and equipment, and more specifically relates to an ironing structure of an automatic leveling paver with a heating function. Background technique [0002] As the core working device of the asphalt paver, the ironing plate directly determines the paving quality and performance of the machine. At present, the ironing plate of asphalt paver at home and abroad all adopts a rectangular box structure welded by steel plates, and the bottom is fixed with a wear-resistant bottom plate by bolts. When paving hot mix asphalt mixture, the base plate of the ironing plate of the paver will be heated to a high temperature above 130°C, while the upper part of the ironing plate box is at ambient temperature. Due to the large temperature difference between the top and bottom of the ironing plate box structure, the expansion of the lower part of the ironing plate at high temperature is much larger tha...
