The invention relates to the technical field of installation of four-foot hollow square blocks of surface protecting blocks, in particular to an automatic unhooking and placing device for four-foot hollow square blocks and a construction method. The automatic unhooking and placing device comprises a top plate, a sleeve and a grapnel, wherein lifting points are evenly distributed at the upper end of the top plate, an opening is formed in the center of the top plate, the sleeve is connected to the lower portion of the opening of the top plate, a sliding way is formed in the wall of the sleeve, the upper part of the grapnel is located in the sleeve, lifting points are uniformly distributed at the upper end of the grapnel, four grapnel pieces are distributed at the lower end of the grapnel in a cross shape, the grapnel is further connected with the sleeve through a pin connected in the sliding way in a sliding mode, and the size of an externally tangent square of the lower end face of the grapnel piece is the same as that of a square hole in the middle of a four-foot hollow square block to be constructed. According to the invention, automatic unhooking is achieved, the safety of an underwater diver in the mounting process can be improved, the mounting duration of each four-foot hollow square block can be shortened compared with an existing mounting process, and then the mounting period of the four-foot hollow square blocks is shortened.

    本发明涉及护面块体的四脚空心方块安装的技术领域,尤其涉及一种四脚空心方块自动脱钩安放装置及施工方法。包括顶板、套筒、抓钩,所述顶板上端均匀分布吊点,顶板中心开口,所述套筒连接于顶板开口下方,套筒壁上开设滑道,所述抓钩上部位于套筒内,上端均匀分布吊点,抓钩下端为十字分布的四个钩片,抓钩通过滑动连接于所述滑道内的销子进一步与套筒连接,所述钩片下端面的外切正方形与待施工的四脚空心方块中间正方形孔洞尺寸相同。本发明通过自动脱钩的实现,不仅能提高水下潜水员安装过程安全性,更能较现有安放工艺缩短每块四脚空心方块的安放时长,从而缩短四脚空心方块安装工期。
