Carrier device

A carrier device comprising:

• a rotating body which is rotatably coupled to a back face of a cab;
• a plurality of wheels which are provided on the rotating body on a back face side of the cab so that a first wheel of the plurality of the wheels provided on a side of one of guide surfaces of a rail and a second wheel of the plurality of the wheels provided on a side of another of the guide surfaces of the rail sandwich the guide surfaces of the rail, wherein at least one of the plurality of wheels is a driving wheel that generates by friction between the driving wheel and the rail, a force that moves the cab in a vertical direction when a longitudinal direction of the rail is the vertical direction, and the driving wheel comes into contact with the one of the guide surfaces and generates, by a friction force between the driving wheel and the rail, a force that moves the cab in a horizontal direction when the longitudinal direction of the rail is the horizontal direction;
• a backing body which extends from the rotating body in a direction of separation with respect to the cab;
• a first wheel support link which is provided on the backing body on a side of a guide surface on a side far from the cab with respect to the rail and which rotatably supports the first wheel of the plurality of wheels;
• and
• a second wheel support link which is provided on the backing body on a side of a guide surface on a side near to the cab with respect to the rail so that the highest point of the second wheel support link is arranged at a position lower than the lowest point of the first wheel support link when the longitudinal direction of the rail is the vertical direction and which rotatably supports the second wheel of the plurality of wheels,
• wherein
• wheels on a side of the first wheel support link are driven when the cab moves in the horizontal direction.

A carrier device, comprising:

• a rotating body which is a pair of divided bodies respectively rotatably coupled to a back face of a cab;
• wheels which are provided on the rotating body so as to sandwich guide surfaces of a rail on a back face side of the cab, wherein at least one of the wheels is a driving wheel that generates, by friction between the driving wheel and the rail, a force that moves the cab in a vertical direction when a longitudinal direction of the rail is the vertical direction, and the driving wheel generates, by a friction force between the wheels and the rail, a force that moves the cab in a horizontal direction when the longitudinal direction of the rail is the horizontal direction;
• a first left-right inclination prevention roller which is in contact with the guide surfaces of the rail;
• a link which is rotatably supported by one of the pair of divided bodies and which rotatably supports the first left-right inclination prevention roller;
• an elastic body which is coupled to the link and the one of the pair of divided bodies;
• a first fore-aft inclination prevention roller which is supported by the other of the pair of divided bodies in a state of being in contact with a side far from the cab of a bottom panel of the rail, wherein the bottom panel is intersected by one of the guide surfaces;
• and
• a second fore-aft inclination prevention roller which is supported by the one of the pair of divided bodies in a state of being in contact with a tip of a guide plate of the rail, wherein a surface of the second fore-aft inclination prevention roller in contact with the tip of the guide plate is intersected by the guide plate.
