Abstract

The invention discloses a crawler paver with a preheating function and a method thereof. The crawler paver comprises an adjusting mechanism, a material transportation mechanism, a vehicle body, a generator and an infrared heater, wherein the material transportation mechanism, the infrared heater, the generator and the adjusting mechanism are all arranged on the vehicle body; the material transportation mechanism comprises a scraper conveyor, a spiral material distribution machine, a vibrating tamper and a screed; the scraper conveyor is arranged on the vehicle body; the scraper conveyor, the spiral material distribution machine, the vibrating tamper and the screed are sequentially connected; the screed is provided with a heating system for heating the screed; the infrared heater is arranged on one side of the spiral material distribution machine; the infrared heater comprises hollow ceramic tubes, electrothermal infrared radiation coatings and electrodes; both ends of each hollow ceramic tube are provided with the corresponding electrodes; the electrothermal infrared radiation coatings are arranged at the surface of the hollow ceramic tubes; and the adjusting mechanism is used foradjusting the screed. The crawler paver with the preheating function reduces the discontinuity between asphalt mixtures and a lower bearing surface caused by temperature, improves the working efficiency and degree of precompaction of the crawler paver, reduces pavement diseases and prolongs the service lives of pavements.

Description

technical field [0001] The patent of the present invention relates to the field of construction machinery, in particular to a crawler paver with infrared preheating function and its method. Background technique [0002] Semi-rigid base asphalt pavement structure is the most basic and widely used pavement structure in my country. It is formed by adding asphalt layer on semi-rigid base, and has mature and systematic design and construction technology. The interlayer treatment between the semi-rigid base and the asphalt surface layer is an important link in the construction of asphalt roads. The road construction in my country has developed rapidly and the overall level has been greatly improved. However, there are still some projects due to short construction period, serious vehicle overloading and continuous high temperature in summer. The reason is that there are quality problems, which greatly affect the road performance and driving safety, and cause double losses of economi...
