PERFECCIONAMIENTOS EN LOS DISPOSITIVOS DE FIJACION DE LISTONES TUBULARES EN UN TRANSPORTADOR DE PASO DE PEREGRINO

摘要

The instant invention is a holder used in a walking-beam conveyor having a plurality of beams each formed of a longitudinal row of longitudinally extending and aligned tubes connected together at these holders. Each holder has a stationary base formed with an upwardly open hole and is provided above the hole with a projection extending longitudinally in one direction and fitting complementarily with one of the ends of one of the tubes. A holder element having an upright shaft engageable snugly in the hole and formed with a projection extending longitudinally in a direction opposite to the base projection normally fits complementarily with one of the ends of another of the tubes. A locking member engageable longitudinally between the hole and the holder element presses the holder element longitudinally in the opposite direction against a face of the hole. Vertically overlapping formations on the element and on the face of the hole prevent upward movement of the element in the hole when the element is pressed against the face by the locking member.
