Abstract

The utility model discloses a building material lifting mechanism, comprising a lifting beam, the upper end of the lifting beam is fixedly connected with a lifting ring, and the lower end of the lifting beam is connected with a round tube lifting frame. The key points of the technical solution are that, by arranging the round tube lifting frame and the plate lifting frame, the round tube lifting frame can be used to limit the round tube-shaped building materials of different diameters, so as to facilitate the lifting of the round tube-shaped building materials. At the same time, the plate lifting frame can also be used to clamp the plate-shaped building materials to lift the plate-shaped building materials. At the same time, building materials of different shapes can be lifted, which is more flexible to use and is used to solve the problem that the shapes of building materials are relatively diverse, and the common ones are plate-shaped building materials and round tube-shaped building materials. In contrast, the lifting device in the patent can only be used to lift the plates in terms of structure, but it is difficult to lift the plates and round tube-shaped building materials at the same time. Therefore, the function is relatively single and the use is not flexible and convenient enough.
