The invention relates to the technical field of object hoisting, and discloses a crane portal frame which comprises two bases, the upper surfaces of the two bases are fixedly connected with fixing blocks, the interiors of the fixing blocks are slidably connected with moving blocks, the upper ends of the moving blocks are fixedly connected with connecting blocks, and the connecting blocks are fixedly connected with the upper ends of the moving blocks. And an I-shaped bearing block is fixedly connected between the opposite sides of the connecting blocks, a position adjusting mechanism is arranged on the I-shaped bearing block, and the position adjusting mechanism comprises a concentric-square-shaped block, a rotating shaft, a rotating gear and a toothed plate. According to the crane portal frame, multiple sets of mechanical structures are used in cooperation, the stability of the hook assembly when a lifted object moves is guaranteed, so that the situation that the object topples over is avoided, the integrity of the object is guaranteed, meanwhile, by means of the mechanical structures, the stability of the crane portal frame in the back-and-forth moving process can be guaranteed, and the situation that the crane portal frame shakes is avoided; the efficiency of the device in actual application is effectively improved, and meanwhile, the completeness of a hoisted object is ensured.

    本发明涉及物体吊运技术领域,且公开了一种起重机龙门架,包括底座,所述底座设置有两组,两组所述底座的上表面均固定连接有固定块,所述固定块的内部滑动连接有移动块,所述移动块的上端固定连接有连接块,所述连接块相对侧之间固定连接有工字型承载块,所述工字型承载块上设置有位置调节机构,所述位置调节机构包括回字型块、转动轴、转动齿轮和齿板。该种起重机龙门架,通过多组机械结构配合使用,保证挂钩组件在起吊物品移动时的稳定性,从而避免物品发生倾倒的情况,保障物品的完整性,同时利用机械结构,能够保证其在来回移动中的平稳性,从而避免出现晃动的情况,有效的提高该装置在实际运用中的效率,同时确保起吊物品的完整性。
