Pipe fitting lifting device used in narrow space

The utility model discloses a pipe fitting lifting device used in a narrow space, which comprises a mobile platform, an electric push rod and a pipe fitting clamping jaw assembly, the fixed end of the electric push rod is fixed on the top surface of the mobile platform, and the driving end of the electric push rod is connected with the pipe fitting clamping jaw assembly; the size of the pipe fitting clamping jaw assembly is matched with the size of a pipe fitting to be lifted, and the projection of the horizontal plane of the pipe fitting clamping jaw assembly completely covers the projection of the horizontal plane of the driving end of the electric push rod. In order to solve the technical problem and realize the corresponding technical scheme, the pipe jacking device utilizes the electric push rod to push the pipe clamping jaw assembly to realize the jacking work of the pipe, and the pipe clamping jaw assembly matched with the pipe in size can effectively reduce the overall size of the device, so that the
