The invention relates to the technical field of steel pipe construction, in particular to a double-curvature blast furnace downcomer hoisting butt joint tool which is characterized in that the ends of two pipelines are tightly hooped through a fixed inner ring and a butt joint inner ring respectively, fasteners are inserted into a fixed outer ring and a butt joint outer ring, and the inner ends of the fasteners abut against the fixed inner ring and the butt joint inner ring; the fixed inner ring and the fixed outer ring as well as the butt joint inner ring and the butt joint outer ring are fixed at a certain angle, and during butt joint, the fixed outer ring and the butt joint outer ring are spliced, clamped and fixed through the teeth and the tooth grooves, so that two pipelines are in tight butt joint, construction operation is facilitated, and the disassembly and assembly process is greatly simplified. The ball body is clamped through the spherical fixing groove, so that the ball body can freely rotate within a certain range, the angle of the lifting hook for lifting the butt joint outer ring can be adjusted, and butt joint of steel pipes is facilitated.

    本发明涉及钢管施工的技术领域,具体是一种双曲度高炉下降管吊装对接工具.通过固定内圈和对接内圈分别紧箍两根管道的端头,在固定外圈和对接外圈上插设紧固件,通过紧固件的内端抵接固定内圈和对接内圈,使固定内圈和固定外圈以及对接内圈和对接外圈之间呈一定角度的固定,在对接时,固定外圈和对接外圈通过齿牙和齿槽拼接卡固,使两个管道之间紧密对接,不仅便于施工操作,还极大简化了拆装过程。通过球形固定槽卡接球体,使球体能够在一定范围内自由转动,使得吊钩吊装对接外圈的角度可以调整,便于对接钢管。
