The invention discloses a manipulator for hoisting a building steel girder. The manipulator comprises a suspension arm, and a turnover device is arranged on the suspension arm, wherein the turnover device comprises a suspension plate fixedly arranged at a lower end of the suspension arm, and turnover grooves with opposite opening directions are symmetrically formed in the left end and the right end of the suspension plate in an up-down penetrating mode; and a turnover arm is rotationally arranged between the front wall and the rear wall of the turnover groove, clamping devices are arranged onthe turnover arms, each clamping device comprises clamping blocks which are arranged at the lower ends of the end faces of the opposite sides of the turnover arms on the left side and the right side in a sliding mode, and locking devices are arranged in the clamping blocks. The manipulator is suitable for hoisting and moving a plurality of steel girders in different models; the steel girder is stably clamped without shaking in the steel girder moving process, the clamping device can be automatically locked when the steel beam is clamped, the situation that the steel girder slides and inclinesbetween the steel girder and the abutting block in the moving process is avoided, the stability is guaranteed when the steel beam is hoisted and moved, and safety is enhanced.
本发明公开的一种用于建筑钢梁起吊的机械手,包括吊臂,所述吊臂上设有翻转装置,所述翻转装置包括固定设于所述吊臂下端的悬吊板,所述悬吊板上左右两端对称且上下贯通的设有开口方向相反的翻转槽,所述翻转槽前后壁之间转动设有翻转臂,所述翻转臂上设有夹紧装置,所述夹紧装置包括滑动设于左右两侧所述翻转臂相对一侧端面下端的夹块,所述夹块内设有锁定装置,本发明可适应起吊移动多种不同型号的钢梁,在移动钢梁的过程中将钢梁稳稳夹紧,而不会出现晃动,并且在夹紧钢梁时可自动锁定夹紧装置,防止钢梁在移动过程中出现与抵块之间出现滑动歪斜的情况,保证起吊移动钢梁时的稳定性,增强了安全性。
