The invention relates to a gantry crane with the high stability for bridge construction. The gantry crane with the high stability for bridge construction comprises a cross beam, a translation block, aprocessor, a lifting mechanism, a translation mechanism, a flat plate, a lifting hook, a connecting mechanism and two supporting columns, the lifting mechanism comprises a driving assembly and four lifting assemblies, and each lifting assembly comprises a driven bevel gear, a rotating shaft, a wire coil, a steel wire rope and two supporting units; and the connecting mechanism comprises a liftingplate, two sliding rings and four connecting assemblies, and each connecting assembly comprises a connecting block, a fastening unit and two rolling wheels. The gantry crane with the high stability for bridge construction achieves safe lifting movement of the flat plate and the lifting hook through tightening or loosening of four steel wire ropes in the lifting mechanism, and the goods are prevented from falling off and the safety accident is prevented; and in addition, the connecting block can move along the axes of the supporting columns through the connecting mechanism, the connecting blockcan be fixed to the lifting plate, the situation that the goods are blown by wind to shake in the transportation process is avoided, the transportation stability is guaranteed, and the practicabilityof the equipment is improved.

    本发明涉及一种用于桥梁施工的稳定性高的龙门吊,包括横梁、平移块、处理器、升降机构、平移机构、平板、吊钩、连接机构和两个支柱,升降机构包括驱动组件和四个升降组件,升降组件包括从动锥齿轮、转轴、线盘、钢丝绳和两个支撑单元,连接机构包括升降板、两个滑环和四个连接组件,连接组件包括连接块、紧固单元和两个滚轮,该用于桥梁施工的稳定性高的龙门吊通过升降机构中的四根钢丝绳收紧或者放松实现平板和吊钩的安全升降移动,防止货物掉落和引发安全事故,不仅如此,通过连接机构使得连接块可沿着支柱轴线移动,并可使连接块固定在升降板上,防止货物运输过程中受到风吹而晃动,保证运输的稳定性,提高了设备的实用性。
