AI Technical Summary
The existing foam asphalt in-site cold regeneration device cannot adjust the position height of the rolling device, resulting in the asphalt being unable to be completely compacted. At the same time, the asphalt is prone to solidification and blocking the device, resulting in inconvenience in discharge and laying.
A device including a main body, a crushing roller, a rolling roller, a sliding groove, a support block, a top rod, a restricting rod and a support spring is designed. The support block is moved by a first dual-axis motor, a second transmission group and a moving lead screw, driving the rolling roller to adjust the position, and preventing asphalt from solidification through a heating pipe and a conductive block.
Flexible adjustment of the position height of the rolling device is achieved, ensuring that the asphalt can be completely compacted, and preventing the asphalt from solidifying through heating pipes, simplifying the laying process.
