The invention discloses a disc hole lifting appliance which is used for lifting an annular disc, a center hole extending in the axial direction is formed in the middle of the annular disc, and the disc hole lifting appliance comprises a stand column, a lower base, a lower clamping plate and a telescopic part. The stand column is used for being matched with a center hole of the annular disc. The upright post is inserted into the lower seat; the lower clamping plate is arranged on the upper surface, facing the annular disc, of the lower seat, and the lower clamping plate is provided with a placing surface for placing the annular disc; the telescopic part is connected with the lower clamping plate and can control the lower clamping plate to move in the radial direction of the stand column. The stand column is inserted into the lower base, and the telescopic part can control the lower clamping plate to move in the radial direction of the stand column. The placing surface on the lower clamping plate of the disc hole lifting appliance can realize radial extension and retraction, so that the disc hole lifting appliance can penetrate through the center holes of the annular discs with different diameters, and the placing surface can support the annular discs with different diameters.

    本发明公开了一种盘孔吊具,所述盘孔吊具用于吊装环状盘,所述环状盘的中间具有沿轴向延伸的中心孔,所述盘孔吊具包括立柱、下座、下夹板和伸缩部。所述立柱用于与所述环状盘的中心孔相配合;所述立柱插入所述下座中;所述下夹板设置于所述下座面向环状盘的上表面,所述下夹板具有用于放置环状盘的放置面;所述伸缩部与所述下夹板连接,所述伸缩部能控制所述下夹板沿所述立柱的径向移动。环状盘套设在立柱上,立柱插入下座中,伸缩部能够控制下夹板沿立柱的径向移动。盘孔吊具的下夹板上的放置面可以实现径向伸缩,使得盘孔吊具能够穿过不同直径的环状盘的中心孔,放置面能够支撑不同直径的环状盘。
