Equipment for leveling large-span light truss bridge surface
The invention discloses equipment for leveling a large-span light truss bridge surface. The equipment comprises a truss body, wherein the front part, the middle part and the rear part of a lower end of the truss body are respectively provided with a main spiral roll shaft, a first main leveling roll shaft and a second main leveling roll shaft, and the main spiral roll shaft comprises a first spiral roll shaft and a second spiral roll shaft. Truss type suspended walking is adopted, walking devices are arranged at a left end and a right end, and overall lifting is achieved through the thread transmission effect of a second lead screw and a second inner thread sleeve; the paving and leveling system is composed of a main spiral roller shaft and two main leveling roller shafts; the spiral roll shaft adopts positive and negative spirals and a scraping plate to distribute materials, and stirring is carried out again in the paving process, so gravel materials in the concrete are more uniform, and surface shrinkage of the bridge floor after final setting is more uniform. The two leveling roll shafts are subjected to rotary excitation, so density of concrete on the bridge floor meets the requirement, and slurry is extracted after accurate leveling, so flatness of the bridge floor meets the design requirement.
本发明公开了一种用于大跨度轻型桁架桥面整平的设备，包括：桁架体，所述桁架体下端前部、中部和后部分别安装有总螺旋辊轴、第一总整平辊轴和第二总整平辊轴，所述总螺旋辊轴包括第一螺旋辊轴和第二螺旋辊轴。本发明采用桁架式悬空行走，左右两头有行走装置，整体升降采用第二丝杆和第二内螺纹套管的螺纹传动作用来实现；摊铺平整系统由一根总螺旋辊轴和两根总整平辊轴组成。螺旋辊轴采用正反螺旋及刮平板布料，在摊铺中再次搅拌使砼中的砂石料更均匀，使桥面在终凝后表面收缩更匀称。两根整平辊轴采用旋转激振，使桥面混凝土的密度达到要求，并进行精准整平后提浆，使桥面平整度达到设计要求。
