Device for opening holes in pavement for urban road construction

Abstract

The invention discloses a device for opening holes in a pavement for urban road construction, relating to the technical field of road construction. The device comprises a supporting plate which is connected with a sliding frame in a transmission manner through a lateral adjusting mechanism, and a supporting frame is fixed on the sliding frame; a drilling assembly comprising a drill bit, which extends to the inside of a collecting cylinder, is connected to a driving motor in a driving manner; a supporting assembly is connected to the lower part of the collecting cylinder, a through hole vertically corresponding to the supporting assembly is formed in the sliding frame, and the supporting plate is provided with a strip hole vertically corresponding to the through hole. When the holes are drilled by the drill bit, the surrounding area of the hole can be pressed and stabilized by a pressure plate on the supporting assembly, and also a guiding effect for the drill bit during rotation is achieved, thus fully guaranteeing the drilling quality; scraps generated when the holes are opened can be raised by a spiral blade, and collected through a collecting box, thus being prevented from falling into the holes and causing blockage, and improving the drilling quality.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a device for opening holes in urban road construction road surfaces. Background technique [0002] From the meaning of the word, the road is the infrastructure for various trackless vehicles and pedestrians; according to its use characteristics, it can be divided into highways, urban roads, country roads, factory and mine roads, forestry roads, examination roads, competition roads, automobile test roads, workshop passages As well as school roads, etc., there were also post roads in ancient China. In addition, it also refers to the way to achieve a certain goal, the way things develop and change. In the process of road construction, it is necessary to open holes in the roadbed. [0003] The patent with the authorized notification number CN207988932U discloses a drilling device for municipal construction of roads and bridges, including an outer shell, the lower end of wh...
