Abstract

A road construction device applying an air exhaust fan to dissipate heat is used for polishing a local bulge on a construction road surface during road construction. The road construction device comprises an external shell (8), a motor (9) and a polishing head driving rod component (6), wherein the polishing head driving rod component (6) is driven by the motor (9), the motor (9) can be in power linkage with a splined hole in a driving sleeve part (61) of the polishing head driving rod component (6) in an axial sliding way, and a driving sleeve part (61) of the polishing head driving rod component (6) is fixedly connected with a polishing head installation rod part (62) of the polishing head driving rod component (6) through a reducing connection part (612).

Description

technical field [0001] The present application relates to the field of construction machinery, in particular to a road construction device that uses an exhaust fan to dissipate heat. 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 p...
