The invention belongs to the field of lifting appliances, and provides a furnace bottom plate center positioning lifting appliance which comprises a base plate, a lifting column, a lifting rod, a lifting rod and a lifting rod, the rotating mechanism is arranged on the hoisting column, a rotating block is arranged on the rotating mechanism, and the rotating mechanism is used for driving the rotating block to rotate relative to the hoisting column; and the first hoisting block and the second hoisting block are in a normally-extending state, are arranged at the bottom end of the hoisting column, and can oppositely move away from each other in the radial direction of the hoisting column so as to extend out of the hoisting column. Compared with the prior art, the lifting appliance has the advantages that the traction grooves are movably clamped and matched with the traction blocks, so that the lifting columns smoothly penetrate through the lifting holes in the furnace bottom plate when the two lifting blocks contract, and the furnace bottom plate is limited on the lifting appliance when the lifting blocks are reset to a normally-extending state, and the operation flexibility of workers and the overall working efficiency are improved; and the smoothness and the stability when the furnace bottom plate is hoisted are ensured.
本发明属于吊具领域,提供了一种炉底板中心定位吊具,包括:基板,其上配置有吊装柱,吊装柱与基板垂直设置,且吊装柱活动插设于吊装孔;转动机构,设置在吊装柱上,转动机构上设置有转动块,用于驱动转动块相对吊装柱进行旋转运动;处于常伸出状态的第一吊装块和第二吊装块,设置在吊装柱的底端,第一吊装块和第二吊装块能够沿吊装柱的径向方向相向远离以伸出至吊装柱外。与现有技术相比,本发明的优点在于利用牵引槽与牵引块活动卡接的配合,实现两个吊装块收缩时供吊装柱顺利穿过炉底板上的吊装孔,并在复位至常伸出状态时将炉底板限制在该吊具上,提升工人操作时的灵活性以及整体的工作效率,保证吊装炉底板时的流畅性和稳定性。
