Modular partition hot air circulating-type bituminous pavement heating machine

Abstract

The invention discloses a modular partition hot air circulating-type bituminous pavement heating machine which comprises a rack (1). A driving cab (10), an air tank assembly (3), a fuel tank (2) and apower device (4) are arranged above the rack (1) from front to back, and the left side and the right side of the power device (4) are provided with gasification devices (9). The front end and the rear end of the rack (1) are each movably connected with a set of heating walls (6) through a heating wall lifting and overturning swing frame assembly (7), and the position, between a front axle and a rear axle, of the lower portion of the rack (1) is movably connected with a set of heating walls (6) through a heating wall lifting sliding frame assembly (8). According to the modular partition hot air circulating-type bituminous pavement heating machine, the modular partition heating temperature is accurately controlled, and uniformity of the whole heating face is ensured; the machine has the good adaptability to large curve construction, large angle climbing, site-transferring transporting and the like; and modular heating wall variable-power and intermittent heating and machine-group control are achieved, the heating efficiency is high, the heating depth is large, and the adaptability to the disease damage working condition is high.

Description

technical field [0001] The invention relates to a modular partition hot air circulation type asphalt pavement heating machine, in particular to a hot air circulation heating machine for in-situ heat regeneration trains on asphalt pavement, which belongs to the field of road maintenance equipment. Background technique [0002] The heating machine is used to heat and soften the asphalt pavement. The in-situ heating technology is a core technology of in-situ thermal regeneration. At present, the heating machines of domestic and foreign manufacturers mainly have the following defects: [0003] (1) The road surface is scorched and the environment is polluted. Most pavement heaters use fuel / gas open flame heating and gas infrared heating. The heating temperature of asphalt pavement is not easy to control accurately, which may easily cause aging and coking of asphalt on the 1mm-5mm surface layer of asphalt pavement. Often accompanied by a large amount of toxic blue smoke, there is...
