A device capable of stably lifting a prefabricated cement pipe relates to a lifting appliance, four spring plates (13) which extend back to back along the axial direction of a sleeve (14) are respectively arranged on the side walls of two ends of the sleeve (14) at intervals, and L-shaped rods (11) with one ends perpendicular to the spring plates (13) are fixedly connected to the outer edge surfaces of the end parts of the two groups of spring plates (13); a sliding rod is arranged to be of a movable structure, when a cement pipe is hoisted, the sliding rod is driven by the dead weight of the cement pipe to move upwards till the top end of the sliding rod and the top end of a vertical rod reach the level, the sliding rod moves to drive a rectangular pyramid table A to move, and therefore the rectangular pyramid table A and a rectangular pyramid table B clamp a casing pipe, a spring plate arranged on the casing pipe is ejected to deform, and the casing pipe is hoisted. Therefore, the ends of the L-shaped rods are supported on the inner wall of the cement pipe respectively, the cement pipe is not prone to slipping, and the purposes that the single side of the supported cement pipe is not prone to slipping, and stable installation of the cement pipe is guaranteed are achieved.
一种能够平稳吊装预制水泥管的装置,涉及一种吊具,在套管(14)两端的侧壁上分别间隔设有四个沿套管(14)轴向背向延伸的弹簧板(13),在两组弹簧板(13)端部的外缘面上均固接有一端垂直于弹簧板(13)的“L”形杆(11);本发明通过将滑杆设置为活动结构,吊起水泥管时水泥管的自重带动滑杆上移,直至滑杆的顶端和立杆的顶端达到水平,滑杆的移动带动四棱锥台A移动,从而使四棱锥台A和四棱锥台B对套管进行夹持,套管上设置的弹簧板被顶变形,从而使多根“L”形杆的端部分别撑在水泥管的内壁上,使水泥管不易滑脱,实现了托起水泥管单边也能不易滑脱保证水泥管平稳安装的目的。
