Extrusion type 3D printing robot for repairing early cracks and mild potholes of asphalt pavement
The invention provides a design idea of an extrusion type 3D printing robot for repairing early-stage cracks and mild pit slots of an asphalt pavement, and provides a repairing scheme which can be widely applied to repairing and maintenance of asphalt damaged parts and is high in automation level, high in precision and high in controllability. The problems that an existing gantry type three-axis 3D printing robot is lack of maneuverability and flexibility and is limited by the three-axis size when being used for in-situ repair and maintenance engineering of early cracks and light pit slots of asphalt pavements are solved. Compared with the traditional molten asphalt, the solid asphalt particles adopted by the device have lower requirements on storage and transportation conditions, and are immediately molten when being used, so that the aging phenomenon in the asphalt storage and transportation processes is reduced, and the quality of the asphalt material is ensured; according to the device, flue gas generated by heating asphalt is treated through the waste gas purification assembly mainly composed of the plate type absorption tower and the activated carbon box, and the influence of the flue gas on the environment and the life health of constructors is relieved.
本发明提供了一种沥青路面早期裂缝及轻度坑槽修补挤出式3D打印机器人设计构想，提出了一种能广泛应用于沥青破损处修补养护的高自动化水平、高精度、可控性强的修补方案；克服了现有龙门式三轴3D打印机器人用于沥青路面早期裂缝和轻度坑槽原位修补养护工程中缺乏机动性、灵活性、受三轴尺寸限制的问题；较传统的熔融沥青而言，本装置采用的固态沥青颗粒对储存和运输的条件要求较低，即用即熔，减轻了沥青储存和运输过程中的老化现象，保证沥青材料质量；本装置通过主要由板式吸收塔和活性炭箱组成的废气净化组件对沥青加热产生的烟气进行处理，减轻了其对环境和施工人员生命健康的影响。
