AI Technical Summary
Existing crack sealing machines are inconvenient to operate when repairing cracks in asphalt roads, especially when the cracks are irregular or complex in shape. They are difficult to continuously inject asphalt, and the equipment adjustment is time-consuming and labor-intensive, affecting construction efficiency and effectiveness.
An asphalt road crack filling and repair device was designed, which adopts a ball-sleeve universal connection injection gun and a foot-triggered brake assembly to achieve flexible swing and stability of the injection gun, adapt to complex crack shapes, and adapt to different operators through adjustable tube length and height, ensuring continuous and accurate filling.
It enables continuous asphalt injection under complex crack shapes, simplifies the operation process, improves construction efficiency and accuracy, adapts to various construction environments, and expands the application scope.
