The invention discloses a special U-shaped lifting appliance for quenching heat treatment, which comprises a lifting beam, a plurality of strip-shaped inserting hands, a movable lifting ring and stop blocks, the movable lifting ring is movably arranged on the lifting beam, the stop blocks are arranged on the lifting beam and are positioned on the two sides of the movable lifting ring, the plurality of strip-shaped inserting hands are connected to the lifting beam, and the stop blocks are arranged on the lifting beam. And a U shape is defined by the lifting beam and the long-strip-shaped insertion hand. According to the special U-shaped lifting appliance for quenching heat treatment, on-site lifting operation is not needed, the operation safety risk of workers is avoided, heat radiation injury to operators is completely eradicated, and potential safety hazards are thoroughly eliminated; the device is convenient for an operator of a hoisting crane to quickly hook and hoist the hoisting tool and quickly finish quenching, so that the quenching water-entering operation time is remarkably shortened, the waste problem that the casting cannot be quenched and needs to be returned to a furnace again due to excessive temperature reduction caused by long water-entering operation time is avoided, meanwhile, the temperature drop of the casting is reduced, and the product quality after one-time quenching is ensured; the production efficiency is improved.

    本发明公开了一种淬火热处理专用U型起吊吊具,包括提升梁、多个长条型插手、活动吊环、止挡块,活动吊环可移动地设置在提升梁上,止挡块设置在提升梁上并位于活动吊环的两侧,多个长条型插手连接于提升梁,并且提升梁与长条型插手围出U型。本发明的淬火热处理专用U型起吊吊具无需现场起吊操作,避免工人操作安全风险,杜绝操作人员的热辐射伤害彻底消除安全隐患;便于起吊行车操作人员快速串钩吊起吊具,快速完成淬火,由此显著缩短淬火入水操作时间,避免因入水操作时间长导致铸件温度降低过多而无法进行淬火并需重新回炉的浪费问题,同时,减小铸件温降,保证了一次淬火后产品质量,提高生产效率。
