Asphalt pavement crack pouring device and method

DONG FANG / WANG GANG / LIU YINWEI

The invention provides an asphalt pavement crack pouring device and method. The asphalt pavement crack pouring device comprises a frame, a hot melting box and a spray gun are arranged on the frame, the spray gun comprises a conveying pipe and a nozzle, one end of the conveying pipe is connected with an outlet of the hot melting box through a material conveying pump, and the other end of the conveying pipe is connected with the nozzle; a connecting assembly with the adjustable inner diameter is arranged between the conveying pipe and the nozzle and comprises an outer pipe, an elastic hose coaxial with the outer pipe is arranged in the outer pipe, the conveying pipe and the nozzle are communicated through the elastic hose, an inflation cavity is formed between the elastic hose and the outer pipe, and an inflation pump is further arranged on the frame and connected with the inflation cavity through an air conveying pipe. An air outlet communicated with the inflation cavity is formed in the outer pipe, and a control valve is arranged at the air outlet. The inner diameter of the elastic hose can be adjusted in real time according to the crack depth, and the pressure intensity during discharging of the nozzle is adjusted, so that the crack pouring requirements of different crack depths are met.

本发明提出了一种沥青路面灌缝装置和方法，沥青路面灌缝装置包括车架，车架上设置有热熔箱和喷枪，喷枪包括输送管和喷嘴，输送管一端通过输料泵与热熔箱的出口相连，另一端与喷嘴相连，输送管与喷嘴之间设置有内径可调的连接组件，连接组件包括外管，外管内设置有同轴线的弹性软管，输送管和喷嘴通过弹性软管相通，弹性软管和外管之间形成了充气腔，车架上还设置有充气泵，充气泵通过输气管与充气腔相连，外管上设置有与充气腔相通的出气口，出气口处设置有控制阀。本发明可根据裂缝深度实时调整弹性软管的内径，调节喷嘴出料时的压强大小，从而满足不同裂缝深度的的灌缝需求。
