High precision planar array CCD automatic detecting wheel set apparatus

The utility model provides a high precision planar array CCD (Charge Coupled Device) automatic detecting wheel set apparatus. The utility model is characterized in that a plurality of sets of high precision planar array CCDs and a set of rangefinders arranged on the circumference of the detecting wheel set apparatus and a guiding rule are used for detecting information of the wheel set tread, such as physical dimension, abrasion, inner side distance, etc. A lower rotary mechanism is formed by the speed reducer of a cycloid pin gear and a riding wheel which is connected with the chains of a chain wheel and both ends of a rotating shaft. A wheel set supporting positioning mechanism is formed by the actuating cylinder of a hydraulic station, a slide block which is connected with the end of a piston rod, a positioning cross beam and a V-shaped positioning block on a fixing slide block. A rubber wheel spinning up mechanism is installed on the upper part of the wheel set, is compacted tightly by the cylinder, and is rotated by the electrical machine and the drive wheel set of the rubber wheel fixed on the shaft. A push-off positioning buffer gear and an automatic background mechanism are formed by a set of hydraulic cylinders and swing rods. The mechanisms are all connected with a machine frame. All detecting data are communicated with the interface of a control device and can be connected with the network of a technical management system.
