Building foundation construction drilling device with controllable drilling position

Abstract

The invention relates to the field of building construction, and specifically discloses a building foundation construction drilling device with a controllable drilling position. The building foundation construction drilling device comprises a water tank fixedly arranged on a supporting base, wherein a height adjusting assembly for adjusting the height of a lifting column in the vertical directionis arranged on the upper surface of one side of the supporting base; a swinging transverse beam is rotationally arranged at a top end of the lifting column; a supporting cover is fixedly arranged at the bottom of one end of the swinging transverse beam; a rotating disk is hermetically and rotationally arranged at a bottom end opening of the supporting cover; an atomizing nozzle is arranged on oneside of the rotating disk; a drill rod is coaxially, hermetically and rotationally arranged on the rotating disk; and a third servo motor for driving a driving shaft to rotate is arranged on one sideof the supporting cover. The third servo motor can drive the rotating disk to rotate after being started, and the rotating disk which is driven to rotate can enable the drilling position to be evenlycovered with fog water sprayed by the atomizing nozzle, so that flying dust can be suppressed effectively. In addition, the drilling position can be adjusted conveniently through rotation of the transverse beam.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a drilling device for building foundation construction with controllable drilling positions. Background technique [0002] Drilling machinery used in building construction to reinforce foundation piles or pipe piles used in building engineering foundations.

[0003] In the Chinese patent whose authorized notification number is CN 209976456 U, a stable drilling device for building foundation construction is disclosed, which solves the shortcomings of sand and stone splashing in the drilling and difficult adjustment of machine height in the prior art, including Upper seat, lower seat, electric cylinder and drill bit, the bottom of the upper seat is connected and fixed with the lower seat through a fixing column, electric cylinders are welded on both sides of the bottom of the lower seat, and screw threads are installed on both sides of the bottom of the upper seat through a rotating motor Rod, the outer wall of the threaded rod is threaded with an adjustment seat, and the bottom of the adjustment seat is equipped with a drill bit through a rotating motor

But above-mentioned technical scheme also has the following deficiencies in actual use: the use performance is relatively single, the stability is poor, usually only can be drilled, time-consuming and labor-intensive, shadow drilling efficiency is low, and can't carry out dust suppression, use There are certain limitations
