The invention discloses a lifting appliance for a crown block and an automatic hooking and unhooking method of the lifting appliance, solves the problem of how to realize automatic hooking and removing of a high-altitude lifting hook, and belongs to the field of lifting hooks. A left lifting plate and a right lifting plate which are parallel to each other are fixedly arranged on the top end face of a vertically-placed lifted box body (2), and the two lifting plates are identical in structure and are both provided with square lifting holes and rectangular through holes; a traditional method that an anti-falling clamping tongue is arranged in an opening of the lifting hook is changed, the anti-falling clamping tongue is replaced by the turning plate, and the movable turning plate is arranged on the outer side of the opening of the lifting hook; the two lifting hooks are connected to the two ends of the triangular frame lifting beam in a lifting mode with the openings facing inwards, so that the triangular frame lifting beam vertically falls or ascends, and automatic hanging connection and automatic separation of the lifting hooks and the upper square lifting holes are achieved through cooperation of the lifting hooks, the turning plates, the square lifting holes and the rectangular through holes. According to the invention, the operation of automatically hanging the lifting hook and automatically releasing the lifting hook on a high and large box body or a high and large plate type transported workpiece which is vertically placed is realized.

    本发明公开了一种天车用吊具及其自动挂钩脱钩方法,解决了如何实现高空吊钩的自动挂接和摘除的问题,属于起重吊挂钩领域;在立式放置的被吊运箱体(2)的顶端面上固定设置两彼此平行的左侧吊板和右侧吊板,两吊板结构完全相同,均设置有方形吊孔和长方形通孔;改变传统的在吊钩开口内设置防脱卡舌的作法,用翻板代替防脱卡舌,并将活动翻板设置在吊钩开口外侧;将两吊钩开口朝内吊接在三角形框架吊梁的两端,使三角形框架吊梁的竖直下落或竖直上升,通过吊钩、翻板、方形吊孔和长方形通孔的配合,实现了吊钩与上方形吊孔的自动挂接和自动脱离;本发明实现了对立式放置的高大箱体或高大板式被调运工件的自动挂吊钩和自动脱吊钩的操作。
