The invention provides an anti-falling electromagnet steel billet hoisting device and an anti-falling method. The lifting main beam is pulled by a first hoisting mechanism to move up and down; the anti-falling secondary beam is pulled by a second hoisting mechanism to move up and down; the electromagnet sucking disc is mounted below the lifting main beam and is used for adsorbing a steel billet to be lifted; the top of the anti-falling hook is hinged to the lifting main beam, a traction piece is connected to the position away from the hinge point of the anti-falling hook and the lifting main beam, and the other end of the traction piece is connected to the anti-falling auxiliary beam; the second hoisting mechanism is dragged by the traction piece, so that the anti-falling hook has a naturally drooping anti-falling state and an upwards raising release state; when the anti-falling hook is in an anti-falling state, a hook body of the anti-falling hook is located under the steel billet attracted by the electromagnet suction cup. And when the anti-falling hook is in a release state, the electromagnet sucking disc can freely adsorb and release the steel billet. Through the anti-falling hook, the risk of billet falling due to abnormal loss of excitation of the electromagnet suction cup can be ensured continuously in the whole process.

    本申请提供一种防坠落电磁铁吊运钢坯装置及防坠方法,其包括;提升主梁,通过第一起重机构牵引进行上下运动;防坠副梁,通过第二起重机构牵引进行上下运动;电磁铁吸盘,安装于提升主梁下方,用于吸附待吊装的钢坯;以及防坠钩,顶部铰接在提升主梁上,并在远离二者铰接点处连接有牵引件,牵引件另一端连接在防坠副梁上;其中,第二起重机构通过牵引件的牵引,使得防坠钩具有自然下垂的防坠状态和向上扬起的释放状态;当防坠钩处于防坠状态时,防坠钩的钩体位于被电磁铁吸盘吸附的钢坯的正下方;当防坠钩处于释放状态时,电磁铁吸盘能自由地吸附和释放钢坯。本申请通过防坠钩能全程不间断保证电磁铁吸盘异常失磁钢坯坠落风险。
