Abstract

The invention relates to the technical field of pile foundation construction equipment, and discloses a precise drill rod structure for drilling a foundation pile. The precise drill rod structure comprises a top rod body, wherein the left side of the top rod body is fixedly connected with a first cone pattern plate, the outer surface of the front end of an inner cavity of the top rod body is fixedly connected with a top clamping plate, the inner surface of the top clamping plate is movably connected with a connecting plate, connecting pipe shafts are movably connected to the periphery of the center of the connecting plate, first functional pipes are movably connected to the inner surfaces of the connecting pipe shafts, a first inserting plate is fixedly connected to the front end of the connecting plate, and a bottom clamping block is fixedly connected to the right side of the inner cavity of the top rod body. A clamping groove and an inserting groove are formed, so that the connecting pipe shafts, a defining plate, a connector and a limiting plate rotate in a matched mode when the top rod body and a bottom rod body are connected, the phenomenon that the first functional pipes and second functional pipes are twisted off when the top rod body and the bottom rod body are connected is prevented, and the service lives of the first functional pipes and the second functional pipes are prolonged.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction equipment, in particular to a precision drill rod structure for foundation pile drilling. Background technique [0002] The drill pipe is generally a hollow structure, with air pipes and slurry pipes axially pierced inside. In many cases, hydraulic A pipes and hydraulic B pipes are also provided. There is a hydraulic reaming mechanism at the bottom of the rod, and the hydraulic A pipe and the hydraulic B pipe are connected to the hydraulic pump and the hydraulic cylinder of the hydraulic reaming mechanism at the bottom of the drill pipe through the top of the drill pipe. Based on various considerations such as safety, process, and convenient operation, the drill pipes that need to drill tens of meters deep pile holes are generally composed of multi-section drill pipes. In addition to the structure in which the outer hexagonal column and the inner hexagonal hole are fitted and...
