Device for fixing the kingpin of a semi-trailer to the platform car

摘要

The utility model relates to the field of railway transport, namely devices for fixing the kingpin of a semi-trailer to the platform car used to transport it. The device for fixing the kingpin of the semi-trailer to the platform car comprises a saddle device, a drive with mechanical transmission and a folding cover to protect the housing and the moving part from external influences, whereas the saddle device in turn consists of a moving part comprising the fixing mechanism of the kingpin of a semi-trailer that precludes vertical movement of the kingpin of a semi-trailer, taking into consideration that the deviation of the kingpin from the longitudinal axis of the car during loading is within 0 to 190 mm, and an immovable part comprising a base attached to the frame of the platform car and a rotating body attached to it, whereas the moving part is designed to move longitudinally along the immovable part of the saddle device from 0 to 350 mm in both directions, whereas the contact surfaces of the moving and immovable parts are made of materials with ultra-low friction coefficient. The technical result of the utility model is simplifying the structure, increasing reliability, reducing the time required to load semi-trailers and reducing the labor intensity of loading.
