Abstract

Environmentally friendly road construction equipment is used for grinding local bulges on construction road surface during road construction, and comprises an external housing (8), a motor (9) and a grinding head drive lever member (6) driven by the motor (9), the motor (9) is in axial slidable power connection with a spline hole in a drive sleeve portion (61) of the grinding head drive lever member (6) by a fixedly connected spline rod (91), and the drive sleeve portion (61) of the grinding head drive lever member (6) is fixedly connected with a grinding head mounting rod portion (62) of the grinding head drive lever member (6) by a gradual contractile connecting portion (612).

Description

technical field [0001] The application relates to the field of construction machinery, in particular to an environment-friendly 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] The object of the present invention is to provide an environment-friendl...
