The invention discloses a GIS in-place hoisting mechanism for a narrow space, and relates to the field of hoisting equipment, the GIS in-place hoisting mechanism comprises a crane main body and spider legs, the top of the crane main body is rotatably provided with a rotating disc, the top of the rotating disc is provided with a fixed seat, and a bidirectional screw is arranged in a groove in the top of the fixed seat; and a driving mechanism is mounted at the top of the rotating disc. According to the invention, the hydraulic cylinder is matched with the rotation of the two-way screw rod, so that when the lifting hook of the lifting arm mechanism lifts equipment in a narrow space, the equipment can be transported from the back to the front without exiting from the narrow space, and an inclined lifting arm in the prior art is changed into a vertical lifting arm through the matching of the hydraulic cylinder and the two-way screw rod; the lifting arm in the vertical state plays a larger role in a narrow space, the lifting arm mechanism can still incline through stretching and retracting of the hydraulic cylinder, the function of an original lifting arm is played, and the use range of the lifting mechanism is effectively widened.

    本发明公开了一种用于狭小空间的GIS就位吊装机构,涉及吊装设备领域,包括吊机主体与蜘蛛腿,所述吊机主体的顶部转动安装有转动盘,所述转动盘的顶部安装有固定座,所述固定座顶部凹槽的内部设置有双向螺杆,所述转动盘的顶部安装有驱动机构。本发明通过液压缸配合双向螺杆的旋转,实现了吊臂机构的吊钩在狭窄空间吊运设备时,不需要退出狭窄空间即可将设备从背后运至前方,将现有技术中的倾斜吊臂通过液压缸与双向螺杆的配合,转变为竖直吊臂,竖直状态的吊臂在狭窄空间发挥更大,并且通过液压缸的伸缩,依然可以实现吊臂机构的倾斜,发挥原有吊臂的作用,有效的增加了吊装机构的使用范围。
