Abstract

A road construction device capable of utilizing an induction fan for efficiently dissipating heat is used for polishing a local protrusion on a construction road surface when a road is constructed and comprises an external shell (8), a motor (9) and a polishing head driving rod component (6) driven by the motor (9). The motor (9) is in power connection with spline holes in a driving sleeve portion (61) of the polishing head driving rod component (6) through fixedly-connected spline rods (91) in an axial sliding manner; and the driving sleeve portion (61) of the polishing head driving component is fixedly connected with a polishing head mounting rod portion (62) of the polishing head driving rod component (6) through a gradually-contracting connecting portion (612).

Description

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