The invention discloses a construction site steel pipe hoisting device with high safety, which comprises two semicircular insertion pieces, one end of each insertion piece is rotatably connected with a connecting ring, a supporting structure is arranged in each connecting ring, and the other end of each insertion piece is rotatably connected with the corresponding connecting ring. The supporting structure is connected with the two inserting pieces, a ratchet wheel roller is arranged on one side of the connecting ring, a lifting plate is movably connected to the lower end of the connecting ring, connecting holes are formed in the two ends of the lifting plate, and linkage ropes are movably connected into the connecting holes. The bottoms of bundled steel pipes can be fixed and lifted from the two ends, and the situation that the steel pipes incline towards one side in the lifting process and then fall off is avoided. The insertion piece is inserted into the lower steel pipe of the bundled steel pipes, and then the ratchet wheel roller is rotated. And the ratchet wheel roller tensions the connecting rope, so that the stretching blocks extrude the insertion pieces on the two sides towards the two sides, and the insertion pieces and the steel pipe are forced to be fixed.

    本发明公开了一种安全性高的建筑工地钢管吊运装置,包括插入片,所述插入片的形状为半圆形,所述插入片的数量为两个,两个所述插入片的一端均转动连接有连接环,所述连接环的内部设有支撑结构,所述支撑结构分别于两个插入片相连接,所述连接环的一侧设有棘轮滚筒,所属连接环的下端活动连接有提升板,所述提升板的两端均设有连接孔,所述连接孔中活动连接有联动绳。能够从两端对成捆钢管的底部进行固定和提拉,避免钢管在吊运过程中向一侧倾斜进而掉落。将插入片插入到成捆钢管的下层钢管内,随后旋转棘轮滚筒。棘轮滚筒拉紧练连接绳,使得拉伸块将两侧的插入片向两侧挤压,迫使插入片与钢管进行固定。
