The invention discloses a pipe lifting device, and relates to the field of lifting slings, the pipe lifting device comprises a fixing plate, a second stepping motor is arranged in the center of the fixing plate, a cantilever beam plate is arranged in the middle height position of a vertical rod, and a first stepping motor is arranged at the top end of the cantilever beam plate; an output shaft of the first stepping motor and an output shaft of the second stepping motor coincide with the axis of the fixing plate in the vertical direction, and an assembling mechanism is arranged at the top end of the vertical rod. According to the lifting appliance, the lifting appliance is suspended and erected at the top end of the pipe through a locomotive suspension arm, the lifting appliance slowly falls down from the end opening of the top end of the pipe, the outer arc-shaped tiles are located on the outer side of the pipe opening, the inner arc-shaped tiles are located on the inner side of the pipe opening, and the three sets of inner arc-shaped tiles and outer arc-shaped tiles can be attached to the side walls of the pipe opening correspondingly; if an existing clamp clamps a pipeline with too large force, the side wall of the pipe can be extruded into an oval shape, and contour deformation cannot be caused when the clamp clamps the pipe wall.

    本发明公开了一种管材吊运装置,涉及吊具领域,包括固定板,所述固定板的中心位置设置有第二步进电机,立杆中间高度的位置设置有挑梁板,所述挑梁板的顶端设置有第一步进电机,所述第一步进电机的输出轴和第二步进电机的输出轴分别与固定板的轴心在竖直方向上重合,所述立杆的顶端设置有组装机构。在本发明中机车吊臂将吊具悬停竖立管材的顶端,吊具从管材的顶端端口缓慢落下去,外弧形瓦处在管口外侧,内弧形瓦处在管口的内侧,三组内弧形瓦和外弧形瓦会分别贴合在管口的侧壁上,相比现有技术的夹持管材,以往的夹具如果夹持管道太用力的话,管材侧壁会被挤压成椭圆形,本发明的夹持对管壁夹持不会造成轮廓变形。
