The invention relates to the technical field of box girder hoisting equipment, in particular to a hoisting auxiliary device for box girder transportation, a first mounting plate is used for connecting and fixing a box girder, when the box girder is subjected to unbalance loading, a first connecting plate deflects, at the moment, a rolling ball in an arc-shaped pipeline rolls, and the box girder is hoisted; at the moment, a position sensor controls a first hydraulic air cylinder on the corresponding side to start through a control system to drive a first sliding frame on the corresponding side to slide towards the position close to the middle of a first connecting plate, so that force borne by the left side of the first connecting plate is reduced, and a rolling ball can return to the middle position of the arc-shaped pipeline; at the moment, the force borne by the left side and the right side of the first connecting plate can be equal, leveling of the box girder is facilitated, stability of the box girder during hoisting movement is facilitated, meanwhile, protection of the hoisting mechanism is facilitated, and the box girder hoisting device has wide application prospects in the technical field of box girder hoisting equipment.
本发明涉及箱梁吊装设备技术领域,尤其是一种箱梁运输用吊装辅助装置,过第一安装板对箱梁进行连接以及固定,在箱梁发生偏载时,第一连接板发生偏转,此时弧形管道内的滚球发生滚动,此时位置传感器通过控制系统控制其对应侧的第一液压气缸启动,带动其对应侧的第一滑动框向靠近第一连接板中部的位置滑动,使得第一连接板上的左侧受到的力减小,滚球可回复至弧形管道的中部位置,此时可使得第一连接板上左右两侧受到的力相等,有利于对箱梁进行调平,便于其在吊装移动时的稳定性,同时有利于对吊装机构进行保护,在箱梁吊装设备技术领域有着广泛的应用前景。
