The utility model discloses a connecting device for pile driving drill pipe of construction engineering, which comprises an upper drill pipe, a lower drill pipe and a spiral blade. One end of the upper drill pipe is welded with the upper connecting sleeve, the other end of the upper drill pipe is connected with the drill or drill pipe, the other end of the lower drill pipe is welded with the lower connecting sleeve, and the other end of the lower drill pipe is connected with the drill or drill pipe. The upper connecting sleeve and the lower connecting sleeve are connected The rectangular teeth of the sleeve are connected by inlaying, and the joint of the upper connection sleeve rectangular teeth and the lower connection sleeve rectangular teeth inlaying is processed with a pin shaft hole, one end of the pin shaft is assembled with a boss limit in the pin shaft hole, and the opening of the pin shaft hole is provided with a snap ring groove, and the snap ring groove is equipped with a snap ring. The technical scheme solves the problem of slag removal obstruction, reduces the stress on the drill pipe, and improves the service life of the drilling machine. The rectangular gear shaper connection is adopted between the upper drill pipe and the lower drill pipe to transfer the torque, so that the relative distance between the upper and lower spiral blades is reduced, the slag removal is smoother and the slag removal continuity is maintained.

一種建筑工程打樁鉆桿連接裝置
本技術涉及一種鉆桿,特別適用于建筑、橋梁工程打樁鉆孔施工時使用。
技術介紹
目前,在工程建筑打樁鉆孔時,常使用的鉆桿均采用法蘭連接,公開號CN104912476A公開了一種液壓打樁設備的旋控打樁機構,該機構旋動力裝置是通過連接法蘭與鉆套連接,鉆套內設置螺旋鉆桿,由于法蘭外徑比鉆桿直徑大,占用螺旋葉片空間的50%,影響排渣,且法蘭之間的連接采用螺釘易“銹死”,拆裝不便,費時費力,另一種鉆桿的連接方式是采用內、外六方連接,其缺點是,中空直徑小,加工難度大,成本高。
技術實現思路
本技術的任務是提出一種延長鉆桿壽命,排渣順暢的一種建筑工程打樁鉆桿連接裝置。本技術的任務是這樣完成的,包括上鉆桿、下鉆桿和螺旋葉片,其特征在于:所述上鉆桿一端與上連接套焊接構成一體,且上鉆桿的另一端與鉆機或鉆桿連接,所述下鉆桿一端與下連接套焊接構成一體,且下鉆桿的另一端與鉆頭或鉆桿連接,所述上連接套和下連接套的矩形齒是采用鑲嵌方式連接,且上連接套矩形齒和所述的下連接套矩形齒鑲嵌連接接合處加工有銷軸孔,銷軸一端裝配銷軸孔內有凸臺限位,且銷軸孔的開口處設置有卡簧槽,卡簧槽里裝有卡簧。上連接套和下連接套是兩個對稱的形狀如同齒圈狀,每一個齒圈上加工至少三個矩形齒,上連接套上的矩形齒鑲嵌在下連接套的齒槽里,下連接套上的矩形齒插裝在上連接套的齒槽里構成一個整體。且上、下連接套采用3-6公分的圓鋼板加工而成,在上、下連接套的矩形齒插裝結合處加工有一個半圓的銷軸孔,兩個半圓軸孔組裝在一起構成一個完整的銷軸 ...
