The invention relates to the technical field of hook falling prevention, in particular to a novel hook falling prevention device which comprises a magnetic attraction assembly installed on a hook, the magnetic attraction assembly comprises a magnetic base, a control switch rotationally arranged on one side of the magnetic base, a falling prevention piece used for controlling attraction or release of magnetic force, and a locking piece used for abutting against the hook, the nylon belts are symmetrically mounted on two sides of the magnetic base and are used for being connected with a lifting hook; the middle part of the protection assembly is provided with an accommodating cavity for allowing the control switch to pass through; the cleaning assembly is connected with the control switch and blows air to the control switch when rotating along with the control switch. The lifting hook has the beneficial effects that the control switch is rotated to drive the magnetic block to rotate so as to control attraction or release of magnetic force, when the magnetic block is in an attraction state, a worker can place the magnetic base at a proper position of the lifting hook, the magnetic attraction fixing effect is achieved, and the lifting hook is suitable for the lifting hook which is damaged or does not have an anti-falling device.

    本发明涉及吊钩防脱技术领域,特别是一种新型吊钩防脱装置,包括,安装于吊钩上的磁吸组件,其包括磁力座,转动设置于所述磁力座一侧的控制开关,用于控制磁力的吸合或放开,设置于远离所述控制开关一侧的防脱件,用于与吊钩抵接,对称安装于所述磁力座两侧的尼龙带,用于与吊钩连接;防护组件,其中部开设有容纳控制开关穿过的容腔;清理组件,其与所述控制开关连接,当跟随所述控制开关转动时将气体吹向控制开关。本发明的有益效果为通过转动控制开关带动磁性块转动,以控制磁力的吸合或放开,当磁性块处于吸合状态时,工作人员可将磁力座放置在吊钩适宜的位置处,实现磁吸固定的效果,适用于破损或无防脱装置的吊钩。
