The invention provides a special-shaped steel pipe hoisting device for construction site construction. The problems that when a steel pipe is hoisted, balance in all directions cannot be guaranteed, the steel pipe cannot be kept in a specific posture, pre-installation is inconvenient, and accidents are caused due to the fact that the steel pipe is likely to incline and fall down are effectively solved. According to the technical scheme, the device comprises a hanging plate, a plurality of hanging rings are arranged at the upper end of the hanging plate, a circular plate is arranged on the lower side of the hanging plate, a middle shaft is arranged on the circular plate, a cylindrical block is arranged at the upper end of the middle shaft, a spherical cavity is formed in the hanging plate, and the outer edge face of the cylindrical block is attached to the side wall of the spherical cavity; a plurality of wing plates are fixed on the periphery of the circular plate, and clamps are arranged on the wing plates; a plurality of square boxes are arranged at the upper end of the outer edge of the circular plate, lead screws are arranged on left side plates of the square boxes, motors are arranged on the lead screws, balancing weights are arranged on the lead screws, and the balancing weights are in threaded connection with the lead screws; a plurality of grooves are formed in the inner side wall of the spherical cavity, a switch is hinged to the interior of each groove, when the cylindrical block drives the switch to swing upwards, the motor corresponding to the switch rotates forwards, and when the cylindrical block drives the switch to swing downwards, the motor corresponding to the switch rotates backwards.
本发明提供了一种工地施工异形钢管吊装装置,有效的解决了钢管吊装时不能保证各个方向平衡,不能够将钢管保持特定的姿势,不方便预安装,而且易倾斜砸落造成事故的问题;其解决的技术方案是,包括吊板,吊板上端有多个吊环,吊板下侧有圆板,圆板上有中轴,中轴上端有圆柱块,吊板上有球形空腔,圆柱块外缘面与球形空腔侧壁相贴;圆板四周固定有多个翼板,翼板上设置夹具;圆板外缘上端有多个方盒,方盒左侧板上有丝杠,丝杠上有电机,丝杠上有配重块,配重块与丝杠经螺纹连接;球形空腔腔内侧壁上开设有多个凹槽,每个凹槽内铰接有开关,当圆柱块带动开关向上摆动时开关所对应的电机正转,当圆柱块带动开关向下摆动时开关所对应的电机反转。
