The invention discloses a relay conversion device for large-tonnage continuous oscillation moving. The relay conversion device comprises connecting blocks, wherein lifting lugs are arranged on the twosides of the upper ends of the connecting blocks respectively, two pull plates are movably connected between the lifting lugs on the two sides through a first pin shaft, a fan-shaped lifting plate ismovably connected between the upper ends of the two pull plates through a second pin shaft, six first lifting holes are evenly distributed in the upper end of the fan-shaped lifting plate, a connecting groove is formed in the lower ends of the connecting blocks, positioning stop blocks are arranged on the connecting blocks on the two sides of the lower ends of the connecting grooves, and positioning holes are formed in the positioning stop blocks. According to the invention, the relay conversion device has the lifting functions of continuous oscillation moving in the air more than two times in a relaying manner and long-horizontal distance converting, has the characteristics of simple operation, low labor intensity, small danger coefficient and low cost, and avoids the arrangement of a middle temporary conversion platform.
本发明公开了一种大吨位连续荡移使用的接力转换装置。包括有连接块,连接块的上端两侧分别设有吊耳,两侧的吊耳之间经第一销轴活动连接有两块拉板,两块拉板的上端之间经第二销轴活动连接有扇形吊板,扇形吊板的上端均匀分布有六个第一吊孔;所述连接块下端设有连接槽,连接槽下端两侧的连接块上均设有定位挡块,定位挡块上设有定位孔。本发明具有空中连续两次以上接力荡移,较远水平距离转换的起重吊装功能,操作简单,人工强度小,避免了中间临时转换平台搭设,危险系数小,成本低的特点的有益效果。
