Drilling device and drilling method for road and bridge municipal construction

Abstract

The invention relates to the technical field of road construction, and discloses a drilling device and drilling method for road and bridge municipal construction. The drilling device for road and bridge municipal construction comprises a base and a drill bit, wherein universal wheels are fixedly arranged at the four corners of the bottom of the base, a through hole is formed in the top of the base, and a box body is fixedly arranged at the top of the base; and a mounting plate is fixedly arranged at the top of the box body, a motor is fixedly arranged on one side of the mounting plate, an output shaft of the motor is fixedly connected with one end of a square rod, a square groove is formed in the top end of the drill bit, and the square rod is slidably connected with the square groove. The drilling device and drilling method for road and bridge municipal construction are reasonable in design, and the drill bit moves downwards at low speed while being driven to rotate at high speed, so that automatic drilling work is carried out, the working efficiency of drilling work is improved, and the uniformity of the drilling size is guaranteed; and dust generated by drilling is sucked into an air outlet barrel by driving fan blades to rotate, and the dust is filtered through a filter screen, so that health damage and environmental pollution caused by the dust are reduced.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a drilling device and a drilling method for municipal construction of roads and bridges. Background technique [0002] Drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target to leave a cylindrical hole or hole on the target by means of rotary cutting or rotary extrusion. In the process of road and bridge construction, drilling machines are often used to drill holes for installing roadblocks, speed bumps and other devices. Authorized notification number is that the Chinese patent of CN212535543U discloses a kind of drilling device for municipal construction of road and bridge, comprises base plate, and the top of described base plate is respectively fixedly connected with shock-absorbing spring and fixed cylinder, and the quantity of described shock-absorbing spring and fixed cylinder There are several,...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the drilling device used for road and bridge construction in the prior art is prone to uneven drilling size and the drilling efficiency is low, and because it does not have the ability to remove dust, a large amount of dust generated during drilling is caused. Due to the shortcomings of dust affecting the health of users and polluting the surrounding environment, a drilling device and drilling method for municipal construction of roads and bridges are proposed
