The invention belongs to the field of prefabricated box girders, particularly relates to a crane clamp for clamping prefabricated box girders, and provides the following scheme aiming at the problems that an existing box girder hoisting tool is often difficult to adapt to box girders with different sizes and heights, hoisting tools of various specifications need to be prepared, and the cost and the operation complexity are increased. The box girder clamping device comprises a box girder body and two clamping assemblies, the two clamping assemblies are located at the two ends of the box girder body correspondingly and used for clamping the box girder body, and each clamping assembly comprises two upper pressing plates which are symmetrically arranged. The clamping assembly can flexibly adapt to box girder bodies with different longitudinal sizes and heights, the universality and adaptability of the clamping assembly are improved, it is ensured that the clamping assembly can stably clamp the box girder bodies in the hoisting process through the fact that the inserting rods are inserted into the side edge clamping grooves, the rectangular clamping grooves and the inserting grooves and through a locking mechanism of the clamping blocks and the clamping holes, and the clamping efficiency is improved. And slipping or shaking is prevented.
本发明属于预制箱梁领域,尤其是一种用于预制箱梁装夹的起重机夹具,针对现有的箱梁吊装工具往往难以适应不同尺寸和高度的箱梁,导致需要准备多种规格的吊装工具,增加了成本和操作复杂性的问题,现提出如下方案,其包括箱梁本体以及两个夹持组件,两个所述夹持组件分别位于箱梁本体的两端并用于对箱梁本体进行夹持,所述夹持组件包括对称设置的两个上压板,本申请中通过斜夹板的横向移动和主内杆的竖直移动,能够灵活地适应不同纵向尺寸和高度的箱梁本体,提高了夹持组件的通用性和适应性,通过插入杆插入侧边卡槽、矩形卡槽和插入槽内部,以及卡块与卡孔的锁定机制,确保了夹持组件在吊装过程中能够稳定地夹持住箱梁本体,防止滑脱或晃动。
