The invention discloses a limiting type opening beam lifting appliance. The limiting type opening beam lifting appliance changes an existing lifting lug lifting mode and mainly comprises a lifting lugplate, a lifting lug plate stiffening plate, a limiting baffle plate, a limiting device, I-shaped steel and a bolt connecting pair. According to the device, a steel structure bridge is hoisted basedon the lever principle, a group of devices can realize the installation of all segments in place, the operation is convenient, and good economic benefits are achieved. Compared with an opening beam lifting appliance at present, the material waste of a lifting lug and the workload caused by the welding of the lifting lug are avoided, the operation is convenient, and the lifting working efficiency is remarkably improved.

    本发明公开了一种限位式开口梁吊具,本装置改变了现有吊耳吊装方式,主要包括吊耳板、吊耳板加劲板、限位挡板、限位装置、工字钢和螺栓连接副;本装置采用杠杠原理对钢结构桥梁进行吊装,一组装置并可实现所有节段安装就位,不仅操作做方便,而且还具有很好的经济效益。与现阶段开口梁吊具相比,避免了吊耳的材料浪费及吊耳焊接所带来的工作量,且操作方便,吊装工作效率显著提升。
