Abstract

The invention provides a road construction device improving the service life. The road construction device improving the service life is used for conducting polishing on local protrusions on a construction road surface in road construction. The road construction device improving the service life comprises an external shell (8), a motor (9) and a polishing head driving rod component (6) driven by the motor (9), wherein the motor (9) is in power connection with a splined hole in a driving sleeve portion (61) of the polishing head driving rod component (6) in a mode capable of sliding through a fixedly connected spline rod (91), and the driving sleeve portion (61) of the polishing head driving rod component (6) is fixedly connected with a polishing head installing rod portion (62) of the polishing head driving rod component (6) through a gradually-contracting connection portion (612).

Description

technical field [0001] The application relates to the field of construction machinery, in particular to a road construction device with improved service life. 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 road constructi...
