The invention discloses a steel loading and unloading magnetic lifting appliance for constructional engineering construction, and relates to the technical field of constructional engineering machinery. The device comprises a disc body, and first adjusting screw rods which are in meshing transmission with transmission shafts are arranged on the lower surface of the disc body in an annular array; the peripheral side surface of the first adjusting screw rod is in threaded connection with a first threaded guide sleeve; the peripheral side surface of the first threaded guide sleeve is in threaded connection with a second adjusting screw rod through a second threaded guide sleeve; the end part of the second adjusting screw rod is rotationally connected with a central magnetic suction plate; the two sides of the bottom end of the first threaded guide sleeve are hinged to side edge magnetic suction plates through first connecting rods. A transmission shaft rotates under the action of a first bevel gear and drives a first threaded guide sleeve to rotate, so that a center magnetic suction plate and side edge magnetic suction plates on the two sides move at the same time, and under the action of a first gear ring, a second threaded guide sleeve and a second adjusting screw rod, the center magnetic suction plate and the side edge magnetic suction plates move at the same time; the inner diameter of the annular structure defined by the center magnetic suction plates and the side edge magnetic suction plates is gradually increased or decreased, and the annular part hoisting device is suitable for hoisting various annular parts with different diameters.

    本发明公开了一种建筑工程施工用钢材装卸磁吸吊具,涉及建筑工程机械技术领域。本发明包括盘体,盘体下表面环形阵列均设有传动轴相互啮合传动的第一调节螺杆;第一调节螺杆外周侧面螺纹连接有第一螺纹导套;第一螺纹导套周侧面通过第二螺纹导套螺纹连接有第二调节螺杆;第二调节螺杆端部转动连接有中心磁吸板;第一螺纹导套底端两侧均通过第一连杆铰接有侧边磁吸板。本发明通过传动轴在第一锥齿轮的作用下旋转并带动第一螺纹导套转动,使得中心磁吸板和两侧的侧边磁吸板同时移动,并在第一齿轮环、第二螺纹导套和第二调节螺杆的作用下,多个中心磁吸板和侧边磁吸板合围构成的环状结构内径逐渐变大或变小,适用于多种不同直径的环形零件吊装。
