Abstract

The invention discloses a high-precision road construction device which is used for polishing local convex parts on a construction pavement during road construction. The device comprises an external casing (8), a motor (9) and a polishing head driving rod component (6) driven by the motor (9), wherein the motor (9) is in axial slidable power connection with a spline hole in a driving sleeve part (61) of the polishing head driving rod component (6) through a spline rod (91) fixedly connected with the motor; the driving sleeve part (61) of the polishing head driving rod component (6) is fixedly connected with a polishing head mounting rod part (62) of the polishing head driving rod component (6) through a gradual contraction connecting part (612).

Description

technical field [0001] The present application relates to the field of construction machinery, in particular to a high-precision road construction device. Background technique [0002] 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. [0003] 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 not very large, traditional grinding machines are often not suitable due to factors such as equipment costs. Contents of the invention [0004] The object of the present invention is to provide a high-precision road...
