AI Technical Summary

Technical Problem

Existing bridge pile foundation drilling equipment has difficulty in achieving precise positioning when positioning the drill rod, resulting in displacement of individual piles, which increases labor costs and the risk of overall structural instability.

Method used

It adopts a planar moving mechanism, which drives the moving table to move in both directions through horizontal and vertical helical screws. Combined with the lifting mechanism, it achieves precise positioning of the drill rod and is equipped with a water pump and nozzle for cleaning the drill rod.

Benefits of technology

This improved drilling accuracy, reduced labor costs, lowered the risk of single pile position deviation, and ensured the stability of bridge pile foundations.

Abstract

The utility model relates to the technical field of bridge pile foundation drilling, and particularly discloses bridge pile foundation drilling equipment which comprises a base and further comprises a plane moving mechanism, the plane moving mechanism comprises a longitudinal threaded block, a moving table is fixed to the longitudinal threaded block, a lifting mechanism is arranged on the moving table and comprises a lifting table, and a drill rod is arranged on one side of the lifting table. A water tank is arranged on the movable table, a water pump is arranged on one side of the water tank, and one end of the water pump is connected with a sprayer. Through the arrangement of the plane moving mechanism, the transverse power assembly drives the transverse spiral lead screw to rotate and drives the transverse threaded block to transversely translate so as to drive the moving table to transversely translate, and the longitudinal power assembly drives the longitudinal spiral lead screw to rotate and drives the longitudinal threaded block to longitudinally translate so as to drive the moving table to longitudinally translate. According to the drilling device, the movable table can drive the drilling rod to horizontally move longitudinally and transversely, so that the positioning effect is achieved, the drilling accuracy is improved, and the labor cost is reduced.
