The invention relates to a guide infinite rotation type overhead crossing device used for an overhead line system. The device comprises a limiter tube. The two ends of the limiter tube are connected with bearings on the two sides through threaded rotary shafts. The bearings are installed in bearing rotation combination devices. Each bearing rotation combination device is composed of a bearing fixing seat on the inner side and a flat lug fixing base on the outer side in a butt joint mode. The outer end of each flat lug fixing base is connected to a locating cable clamp or a parallel groove clamp. The guide infinite rotation type overhead crossing device can be automatically rotated and adjusted according to the stress and the linear expansion running direction of a lead, the transitional lead can be well limited in a movable range, an electric locomotive pantograph current obtaining smooth transitional function is achieved, the problems of the too large overhead crossing deflection andabrasion are solved, the service life is prolonged, and the overhead crossing device can completely substitute a common overhead crossing device.
