Lifting appliance of bridge deck crane and method for adjusting postures of beam pieces
The invention discloses a bridge deck crane sling and a method for adjusting beam piece postures, and relates to the field of slings. The lifting appliance of the bridge deck crane comprises a lifting main shaft, a rotary support rotationally arranged on the lifting main shaft in a sleeving mode, a rotary mechanism driving the rotary support to rotate around the lifting main shaft, at least two sets of pulleys arranged on the top face of the rotary support, a first lifting rod hinged to the bottom of the lifting main shaft, and a main beam middle hinged to the bottom of the first lifting rod. The transverse leveling mechanism drives the main beam to rotate along a first vertical plane, the second hanging rods are hinged to the two ends of the main beam respectively, the longitudinal balance beam is hinged to the bottoms of the second hanging rods, and the longitudinal leveling mechanism drives the longitudinal balance beam to rotate along a second vertical plane. The third suspenders are hinged to the two ends of the longitudinal balance beam respectively, the second pulleys are connected to the bottoms of the third suspenders, and the first vertical plane is perpendicular to the second vertical plane. The lifting appliance of the bridge deck crane and the method for adjusting the postures of the beam pieces can quickly and efficiently adjust the postures of the lifted beam pieces so as to improve the bridge construction efficiency.
一种桥面吊机吊具及调整梁片姿态的方法，涉及吊具领域。桥面吊机吊具包括起吊主轴、可旋转地套设于起吊主轴上的回转支座、驱动回转支座绕起吊主轴旋转的回转机构、至少两组设于回转支座顶面的滑轮、铰接于起吊主轴底部的第一吊杆、铰接于第一吊杆底部的主梁中部、驱动主梁沿第一竖直平面转动的横向调平机构、分别铰接于主梁两端的第二吊杆、铰接于第二吊杆底部的纵向均衡梁、驱动纵向均衡梁沿第二竖直平面转动的纵向调平机构、分别铰接于纵向均衡梁两端的第三吊杆及连接于第三吊杆底部的至少两个第二滑轮，第一竖直平面垂直于第二竖直平面。桥面吊机吊具及调整梁片姿态的方法能够快速高效的调整吊起梁片的姿态以提高桥梁施工效率。
