Abstract

The invention provides a road construction device with a limiting function, which is used for polishing a partial bulge on a construction road surface in a road construction process. The road construction device comprises an outer shell (8), a motor (9) and a polishing head driving rod part (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 part (6) through a fixedly-connected spline rod (91); and the driving sleeve part (61) of the polishing head driving rod part (6) is fixedly connected with a polishing head mounting rod part (62) of the polishing head driving rod part (6) through a retractable connection part (612).

Description

technical field [0001] The application relates to the field of construction machinery, in particular to a road construction device with a position-limiting function. 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 con...
