The invention provides an automatic leveling double-decked paving ironing device with a heating function. An outer layer ironing plate is connected with an ironing plate main body through a fixing plate provided with a rotary device. Rotary rods are arranged on the outer layer ironing plate and connected with rotary shafts rotationally. The rotary shafts are arranged on the outer side of the fixing plate. The left side of the ironing plate main body is connected with a left side oil cylinder through a left force application component. The right side of the ironing plate main body is connected with a right side oil cylinder through a right force application component. The middle of the ironing plate main body is connected with a middle oil cylinder through a force application component. The left side oil cylinder, the right side oil cylinder and the middle oil cylinder are all arranged at the bottom end of the fixing plate. A heating device is arranged on the ironing plate main body. Leveling devices are arranged on the two sides of the ironing plate main body correspondingly. The curvature and temperature of the ironing plate main body are controlled in real time, and thus the operation quality of pavement paving is improved effectively. In the paving process, the effect that the ironing plate operates on the same horizontal plane is ensured, and thus the phenomenon that the middle segment of a pavement is thinner than the two ends of the pavement due to too long a distance between iron wires and the action of gravity is avoided effectively.
Description
technical field [0001] The invention relates to the field of road surface operation machinery and equipment, and more specifically relates to an automatic leveling and double-layer paving and ironing device 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 mu...
