Highway pavement asphalt flattening device
The invention discloses a highway pavement asphalt flattening device, which comprises a fixing base, a plurality of universal wheels and a flattening device, wherein pre-tightening devices are symmetrically arranged on the two sides of the flattening device, each pre-tightening device comprises a lead screw and a sliding rod, a pushing handle is fixedly installed at the top of each lead screw, andan elastic piece is fixedly connected between each sliding rod and the flattening device. The highway pavement asphalt flattening device is provided with lead screws, the sliding rods and the elasticpieces, the pushing handle is driven to drive the lead screw to move downwards so as to drive the sliding rod to move downwards, then the elastic piece is extruded to generate certain elastic force to act on the flattening device, and when the flattening device downwards extrudes and flattens the asphalt pavement, the spring elastic force generated by the elastic piece also acts on the asphalt pavement through the flattening device, so that hard contact between the flattening device and the asphalt pavement is reduced, the asphalt is uniformly compacted on the uneven pavement, the compactiondegree and the flatness of the asphalt flattened on the uneven pavement are effectively improved, and the quality of the asphalt pavement is improved.
本发明公开了一种公路路面沥青平整装置，包括固定座、若干万向轮和平整装置，所述平整装置的两侧对称设置有预紧装置，所述预紧装置包括丝杆和滑杆，所述丝杆顶部固定安装推动把手，所述滑杆与平整装置之间固定连接有弹性件；本发明通过设置丝杆、滑杆和弹性件，驱动推动把手带动丝杆向下运动，从而带动滑杆向下运动，进而挤压弹性件产生一定的弹力作用于平整装置，平整装置向下挤压平整沥青路面的同时弹性件产生的弹簧弹力同样通过平整装置作用于沥青路面，从而减轻平整装置与沥青路面之间的硬性接触，在路面凹凸不平均匀的压实沥青，有效提高在路面凹凸不平处平整沥青的压实度及平整度，提高沥青路面的质量。
