  • Eccentric universal joint mechanism and eccentric universal joint
    Patent number: 11149884
    Abstract: An eccentric universal joint mechanism, even when there is a lateral displacement between a first pipe and a second pipe, can absorb the displacement and connect the first pipe and the second pipe. The eccentric universal joint mechanism includes: a first sleeve; a second sleeve; and an eccentric universal joint connecting the first sleeve and the second sleeve. The eccentric universal joint includes a first eccentric pipe, and a second eccentric pipe rotatably joined to the first eccentric pipe. A displacement between the center line of the first eccentric pipe and the center line of the second eccentric pipe is determined by the rotational position of the second eccentric pipe.
    Type: Grant

  • Behavior inspection apparatus and behavior inspection method for extensible flexible pipe joint
    Patent number: 10359267
    Abstract: A behavior inspection apparatus includes: a first measurement tool group including a set of first measurement tools each of which measures a first distance change amount that is a change amount of a distance between a first pipe position in the first pipe and a first reference position of a sleeve of the extensible flexible pipe joint; and a second measurement tool group including a set of second measurement tools each of which measures a second distance change amount that is a change amount of a distance between a second pipe poison in the second pipe and a second reference position of the sleeve. The first and second measurement tools are arranged at different positions in a circumferential direction of the sleeve. Displacement positions of the first and second pipes with respect to the joint are computed based on the measurement data by the first and second measurement tool groups.
