The utility model relates to the technical field of highway engineering, in particular to a simple supporting device used when a tunnel ventilation pipeline passes through a trolley. The simple supporting device used when the tunnel ventilation pipeline passes through the trolley comprises a framework and a sliding face, the framework provides support for the pipeline, the framework is installed on an internal supporting structure of the trolley, and the sliding face facilitating sliding of the pipeline is laid on the framework; the framework used for supporting the ventilation pipeline is installed on the internal supporting structure of the trolley, the sliding face facilitating sliding of the ventilation pipeline is laid on the framework, and during construction, the ventilation pipeline penetrates through the trolley through the supporting device, so that the ventilation effect of the ventilation pipeline is effectively guaranteed, and the construction efficiency is improved. And meanwhile, traveling is f
