Abstract

A shock-absorbing road construction device, used for grinding local protrusions on the construction road surface during road construction, comprising an external casing (8), a motor (9) and a grinding head driven by the motor (9) The drive rod part (6), wherein the motor (9) is fixedly coupled with the spline hole shaft in the drive sleeve part (61) of the grinding head drive rod part (6) through a spline rod (91) To slidable power connection, the driving sleeve part (61) of the grinding head driving rod part (6) is connected with the grinding head installation rod part ( 62) Fixed connection.

Description

technical field [0001] The present application relates to the field of construction machinery, in particular to a shock-absorbing 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] It is an object of the present invention to provide a shock-absorbing ...
