Example Embodiment

[0008] Combine below figure 1 The present invention will be described in detail.

[0009] An efficient road construction device according to an embodiment is used to polish local protrusions on the construction road surface during road construction, and includes an outer housing 8, a motor 9, and a polishing head drive rod component driven by the motor 9 6. The motor 9 is axially slidably and dynamically coupled with the spline hole in the driving sleeve portion 61 of the grinding head drive rod member 6 through a fixedly coupled spline rod 91, and the grinding head The driving sleeve portion 61 of the driving rod member 6 is fixedly connected to the grinding head mounting rod portion 62 of the grinding head driving rod member 6 through the tapered connecting portion 612, and the grinding head mounting rod portion 62 is detachably mounted with the grinding head 620. An axially extending key is provided on the outer peripheral surface of the driving sleeve portion 61 for mating w...

Abstract

The invention provides an efficient road construction device which is used for polishing a partial bulge on a construction road surface in a road construction process. The efficient 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 an efficient 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 efficient road construction de...
