The auxiliary safety clamp is arranged on a crane and a lifting hook and used for driving the rolling mill stand to rotate and comprises a clamp structure and a pin structure, the clamp structure is arranged on the crane and used for clamping the rolling mill stand to form two-point lifting, and the pin structure is arranged on the rolling mill stand and used for clamping the rolling mill stand to form two-point lifting. The lifting device is used for transferring the rolling mill stand to rotate to form two-point lifting. The auxiliary safety clamp for hoisting the rolling mill stand mainly solves the problems that the hoisting capacity of a crown block cannot meet the requirements of stand hoisting, the plant height is limited, and a large truck crane cannot be adopted for hoisting, a hydraulic gantry crane is adopted to be matched with a clamp structure, a hoisting point is arranged on the upper middle portion of the gravity center line of the rolling mill stand, and the rolling mill stand naturally droops and rotates through gravity; the lifting height is reduced, the safety risk is reduced, meanwhile, the influence of the plant height and the crown block lifting capacity is avoided, the clamp structure can be repeatedly used, and by means of the lifting method, the installation time is saved.

    本发明公开了一种用于轧机机架吊装辅助安全夹具,其设置于起重机和吊钩上,用于带动轧机机架旋转,包括:夹具结构和销钉结构,夹具结构设置于起重机上,用于夹住轧机机架,形成两点起吊,销钉结构设置在轧机机架上,用于调动轧机机架旋转,形成两点起吊。该用于轧机机架吊装辅助安全夹具,主要解决天车起重能力无法满足机架吊装,且厂房高度受限,无法采用大型汽车吊吊装的条件,采用液压龙门吊配合夹具结构,起吊点设置在轧机机架重心线的中上部,利用重力自然下垂旋转,即降低了起升高度,又降低了安全风险,同时不受厂房高度和天车起重能力影响,夹具结构可以反复使用,采用此吊装方法不仅节省了安装时间。
