Abstract

The invention discloses a drill pipe device of a hydraulic pile driver, and belongs to the field of drill pipe devices of pile drivers. A drill rod connecting sleeve of the drill pipe device is connected to one end of a main shaft of the hydraulic pile driver, the other end of the drill rod connecting sleeve is connected with a drill pipe connecting sleeve, and a rotating connector assembling assembly is installed on the drill pipe connecting sleeve; the drill pipe device comprises the drill rod connecting sleeve, the drill pipe connecting sleeve, a drill pipe upper sleeve, supporting sleeves,a drill pipe, a lower spline sleeve, a drill bit and a drill rod assembly; the lower end of the drill pipe connecting sleeve is connected to the drill pipe upper sleeve, the drill pipe and the lowerspline sleeve in sequence; the centers of the drill pipe connecting sleeve, the drill pipe upper sleeve, the drill pipe and the lower spline sleeve are axial through holes, the drill rod assembly is arranged in the through holes, the drill bit is connected to the lower spline sleeve, and the supporting sleeves are connected into the drill pipe. The drill pipe device has the advantages that the service life of the drill pipe is prolonged, impact force is large, detachment and replacement are convenient, the use cost is lowered, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a drill pipe device of a pile driver, in particular to a drill pipe device of a hydraulic pile driver. Background technique [0002] At present, when people are building or maintaining roads, they need to set up anti-collision guardrails on the roads for traffic safety. Generally, anti-collision guardrails are installed on guardrail piles, and guardrail piles need to be driven into the ground with a hydraulic pile driver. The patent application submitted earlier "A hydraulic piling and drilling machine for highway guardrail", application number 201720488838.9, wherein: the hydraulic piling machine includes a driving mechanism and a hydraulic piling working device, and the hydraulic piling working device is connected to the driving mechanism. [0003] The drive mechanism includes: column (1), lower pressure arm cylinder (2), ladder frame (3), travel motor (4), hydraulic oil tank (5), radiator, lower frame (7), travel assembly (...
