Abstract
An extractor carriage is furnished on each side with an elbow bracket projecting towards its lower portion. To each of these brackets is attached the end of a cable which moves the carriage in its forward direction towards the centrifuging machine. Each cable is protected at its upper portion from sand debris by lateral wings extending from the upper portions of a trough which receives the debris. These cables, as well as a third cable for returning the carriage, are wound around a single motor drum driven by hydraulic motors which are capable of operating at several speeds. The invention may be applied to centrifuging equipment for cast iron pipe.
Claims11
A machine for extracting centrifuged pipe comprising a rolling track oriented substantially horizontally and supporting an extracting carriage, a flexible element for traction of the carriage in two directions including an upper part for movement of the carriage in the reverse direction attached to the rear of the carriage and being positioned in a horizontal plane passing through the axis along which the carriage moves and a lower part for moving the carriage in the forward direction attached to a projection from the lower portion of the carriage, and means for simultaneously driving at the same speed the two parts of the flexible element in both directions, said upper part includes two strands which are symmetric about a vertical plane of symmetry through the carriage and which pass around a balanced wheel provided at the rear of the carriage.
A machine for extracting centrifuged pipe comprising a rolling track which is oriented substantially horizontally, an extracting carriage, a flexible traction element for moving the carriage in forward and reverse directions, the traction element including an upper part for moving the carriage in the reverse direction attached to the rear of the carriage and an upper part for moving the carriage in the forward direction attached to a projection from the lower portion of the carriage, and means for simultaneously driving at the same speed the two parts of the flexible traction element in the two directions, said driving means comprising a two-speed motor.
