The invention belongs to the field of bridge construction, and particularly discloses a rotary lifting appliance for bridge construction, which comprises an upper cross beam, a rotary component and a lower cross beam which are sequentially arranged from top to bottom, the rotating component comprises an upper support, a rotary driving mechanism and a lower support which are sequentially arranged from top to bottom, and the rotary driving mechanism is used for driving the lower support to rotate relative to the upper support; a lifting mechanism is installed on the upper cross beam, the lifting mechanism comprises a rotating disc rotationally connected to the upper cross beam and a rotating driving piece fixed to the upper cross beam and used for driving the rotating disc to rotate, two sets of lifting assemblies used for lifting workpieces upwards are distributed on the rotating disc in the radial direction of the rotating disc, and each lifting assembly comprises a lifting driving piece; a mounting cavity is formed in the lower cross beam, a lever is mounted in the mounting cavity, mercury switches are mounted at the two ends of the lever, and first lifting hooks are hinged to the two ends of the lever. By the adoption of the scheme, the problem that the workpiece needs to be rotated to the needed angle in the horizontal plane in the hoisting process can be solved.

    本发明属于桥梁施工领域,具体公开了一种桥梁施工用旋转吊具,包括从上至下依次设置的上横梁、旋转构件以及下横梁;旋转构件包括从上至下依次设置的上支座、回转驱动机构以及下支座,回转驱动机构用于驱动下支座相对上支座转动;上横梁上安装有提拉机构,提拉机构包括转动连接在上横梁上的转盘以及固定在上横梁上用于驱动转盘转动的转动驱动件,转盘上沿其径向分布有两组用于向上提拉工件的提拉组件,提拉组件包括提拉驱动件;下横梁内开设有安装腔,安装腔内安装有杠杆,杠杆的两端均安装有水银开关,杠杆的两端均铰接有第一吊钩。采用本发明的方案,可以解决吊装过程中需要将工件在水平面内转至所需角度的问题。
