Lifting appliance for box girder steel formwork
The invention discloses a lifting appliance for a box girder steel formwork. The lifting appliance comprises a lower opening channel steel frame, wherein vertical channel steel is fixedly connected to the two sides of the lower opening channel steel frame correspondingly; transverse channel steel is fixedly connected to the tops of the vertical channel steel on the two sides; longitudinal channel steel which is symmetrically arranged is fixedly connected between the transverse channel steel on the two sides; fixed lifting lugs are fixedly connected to the two ends of the transverse channel steel on the two sides; and a lower opening baffle is movably connected to the free end of the lower opening channel steel frame. According to the lifting appliance, when the box girder steel formwork is in an irregular shape, the channel steel on the box girder steel formwork is clamped by the lower opening baffle, then an upper opening transverse movable supporting rod and an upper opening longitudinal movable supporting rod are driven to move through a transverse electric push rod and a longitudinal electric push rod correspondingly, the positions of movable lifting lugs are adjusted, the overall gravity center positions of the lifting appliance and the box girder steel formwork are adjusted through the cooperative cooperation of the fixed lifting lugs and the movable lifting lugs on the lifting appliance, the lifting process of the box girder steel formwork is stabilized, and the operation is simple.
本发明公开了箱梁钢模板吊具，包括下口槽钢框架，所述下口槽钢框架两侧分别固定连接有竖向槽钢，两侧所述竖向槽钢顶部均固定连接有横向槽钢，两侧所述横向槽钢之间固定连接有对称设置的纵向槽钢，两侧所述横向槽钢的两端均固定连接有固定吊耳，所述下口槽钢框架的自由端活动连接有下口挡板。本发明中，当箱梁钢模板是不规则形状时，利用下口挡板卡住箱梁钢模板上的槽钢，再通过横向电动推杆和纵向电动推杆分别带动上口横向活动撑杆和上口纵向活动撑杆移动，调节活动吊耳的位置，通过吊具上的个固定吊耳和活动吊耳协同配合，调节吊具和箱梁钢模板整体的重心位置，稳定箱梁钢模板的起吊过程，操作简单。
