The invention discloses a lifting point device for an embedded sleeve. A traction wheel is rotatably installed on a lifting point device body to achieve adjustment of the large lifting height, then a rotary connecting block is rotatably installed at the lower end of the lifting point device body, and a rotary connecting sleeve is rotatably connected to the lower end of the rotary connecting block. The other end of the rotary connecting sleeve is connected with one end of a lifting hook through a rotary connecting shaft, one end of the rotary connecting shaft is provided with external threads, the other end of the rotary connecting sleeve is provided with internal threads, one end of the rotary connecting shaft is connected with the other end of the rotary connecting sleeve through threads, and the other end of the rotary connecting shaft is fixedly connected with one end of the lifting hook. The rotary connecting sleeve and the rotating connecting shaft are connected through the threads to form a structure capable of extending and retracting the lifting hook in a short distance, when a heavy object is lifted, it can be guaranteed that the lifting hook does not rotate, extending and retracting are achieved through the rotary connecting sleeve, the structure is simple, installation is convenient, and the height adjusting precision of a lifting point is greatly improved; and the rotary connecting block can also rotate axially, and a multidirectional rotation angle is provided.

    本发明公开了一种预埋套管用吊点装置,通过将牵引轮可转动安装于吊点装置主体上实现吊装大高度的调节,然后在吊点装置主体下端转动安装有转动连接块,转动连接块下端转动连接有转动连接套,转动连接套的另一端通过转动连接轴与吊钩的一端连接,转动连接轴一端设有外螺纹,转动连接套的另一端设有内螺纹,转动连接轴的一端与转动连接套的另一端通过螺纹连接,转动连接轴的另一端与吊钩的一端固定连接,利用通过螺纹连接转动连接套和转动连接轴形成可将吊钩短距离伸缩的结构,在吊装重物时,能够保证吊钩不转动,通过转动连接套实现伸缩,结构简单,安装方便,大大提高了吊点的高度调节精度,并且转动连接块还能实现轴向转动,提供多方位转动角。
