The invention discloses an iron turning cleaning device applicable to surface and multiple T slots of a large working platform. The iron turning cleaning device is composed of an iron turning cleaning device, an industrial vacuum cleaner device and a gas pipeline. T-shaped brushes and T-shaped suction heads differing in model can be replaced and regulated according to the actual situation of the surface of the large working platform; when cleaning iron turning, the industrial vacuum cleaner device is turned on to push a cart to walk forwards, a pushing-sweeping plate is used for cleaning iron turning on the surface of the working platform, the T-shaped brushes are used for cleaning iron turning in the T slots of the working platform, a suction head on the surface of the working platform is used for sucking iron turning on the surface and the T slots of the working platform, and the T-shaped suction heads are used for sucking iron turning in the T slots of the working platform through the suction force of a first industrial vacuum cleaner; and an iron turning sweeping device and an iron turning sucking device in the iron turning cleaning device can be independently used. The iron turning cleaning device disclosed by the invention is convenient to operate; and in a cleaning process, the iron turning cleaning device is strong in flexibility, high in working efficiency, good in cleaning effect, strong in suction force to iron turning and wide in application scope, and is capable of reducing the labor intensity of workers and improving the economic benefits of enterprises.
