Abstract

The invention relates to a hydraulic-lifting road construction device. The hydraulic-lifting road construction device used for polishing partial protrusions on constructing pavements during road construction comprises an external shell (8), a motor (9) and a polishing head drive rod part (6) driven by the motor (9), wherein the motor (9) is in axial and slidable power connection with a spline hole in the drive sleeve cylinder (61) of the polishing head drive rod part (6) through a fixedly-connected spline rod (91), and the drive sleeve cylinder (61) of the polishing head drive rod part (6) is fixedly connected with the polishing head mounting rod part (62) of the polishing head drive rod part (6) through a gradually-contracted connecting part (612).

Description

[0001] This application is the application number: 2015104404865, the application date: July 24, 2015, and the title of the invention: a divisional application of a hydraulic lifting road construction device. technical field [0002] The present application relates to the field of construction machinery, in particular to a road construction device with hydraulic lift. Background technique [0003] In some construction sites, such as road construction, etc., local leveling of the subgrade surface is often required, for example, some local protrusions caused by construction defects need to be polished. [0004] The flatness result of this grinding has a great influence on the quality of subsequent pavement surface construction, for example, occasions with high requirements for the levelness of the road surface, such as expressways, have particularly high requirements for such levelness. At the same time, because the amount of material removed in this local grinding is often no...
