The invention discloses a sleeve hoisting device. The sleeve hoisting device comprises a door-shaped frame and two oppositely-arranged circular-arc-shaped clamping plates arranged at the bottom of the frame. The frame comprises movable frames which are symmetrically arranged and slidably connected with each other, the outer sides of the clamping plates are rotationally connected with the corresponding movable frames respectively, transverse lead screws are arranged in the movable frames and close to the tops, threads are arranged in the middles of the lead screws, and two nuts are in threaded connection with the middles of the lead screws. The two nuts are fixedly connected with the corresponding movable frames respectively, and the two ends of the lead screw are connected with the corresponding movable frames in a rotating and sliding mode. The rotation axis of the clamping plate passes through the gravity center of the sleeve, and the sleeve rotates to adjust the pitch angle in a labor-saving manner. Therefore, time and labor are saved when the sleeve is installed through the sleeve installation tool, angle adjustment of the sleeve is convenient, the sleeve is not prone to shaking during adjustment, the collision phenomenon is not prone to happening, and squeezing injury and bumping injury to operators are avoided.

    本发明公开了一种套管吊装装置,包括门字形的框架以及设置在框架底部的两个相对设置的圆弧形的夹板;所述框架包括对称设置的相互滑动连接的活动框,所述夹板的外侧分别与对应的活动框转动连接,所述活动框内靠近顶部设有横向的丝杠,所述丝杠的中部有螺纹,所述丝杠的中部螺纹连接有两个螺母,两个螺母分别与对应的活动框固定连接,所述丝杠的两端与对应的活动框既转动又滑动连接。夹板的转动轴线通过套管的重心,套管通过转动调整俯仰角时很省力。因而通过使用本发明安装套管时不仅省时省力,套管的角度调整也很方便,而且调整时套管不易晃动,因而不容易发生磕碰现象,避免挤伤、碰伤作业人员。
