A transport carriage 3 on which the transported object 2 can be mounted is provided so as to be able to travel along the travel rail 1 while being connected by the travel rail 1, and the transport carriage 3 is pulled by a rope 4 such as a wire rope. And a posture control means 6 for horizontally holding the conveyance carriage 3 when the conveyance carriage 3 is caused to travel along the running rail 1 to constitute a conveyance device. Is.

  In the case of the illustrated example, the travel drive means 5 is rotatable on the side surface of the transport carriage 3 around a base shaft 7 extending in the width direction (direction orthogonal to the paper surface of FIGS. 1 and 2). A base plate 8 is pivotally mounted, and can swing around a swing shaft 9 parallel to the base shaft 7 at a required position in the longitudinal direction of the traveling rail 1 so as to sandwich the base shaft 7 of the base plate 8. The swing plate 10 is pivotally mounted so that the travel rail 1 is sandwiched between the swing plate 10 and the travel roller shaft 11 parallel to the swing shaft 9 so as to roll along the travel rail 1. A rotatable traveling roller 12 is disposed, and a rope 4 such as a wire rope fed from a drum 14 that is rotationally driven by a motor 13 as a driving device is connected to sheaves 15, 16, 17, and 18. 19, 20, 21, 22, and 23 are sequentially wound around and connected to the bracket 24 of the base plate 8, and the cable body 4 is wound around a drum 14 that is rotationally driven by a motor 13. Thus, the transport carriage 3 is pulled and traveled from the point A to the point B along the travel rail 1, while the transport carriage 3 is moved from the drum 14 that is rotationally driven by the motor 13. The vehicle travels from point B to point A along the line. The cord body 4 is stretched substantially endlessly as in the example shown in FIG. 7 by extending the base end wound around the drum 14 and connecting it to the base plate 8. May be.

  Further, the posture control means 6, when traveling along the traveling rail 1 while holding the transport carriage 3 horizontally, a required point (an auxiliary swing shaft 26 described later) on the side surface of the transport carriage 3 away from the base shaft 7. The skip rail 25 is arranged so that the axis line coincides with the locus of the center P), and at a required point away from the base shaft 7 on the side surface of the transport carriage 3, the width direction (the paper surface of FIGS. 1 and 2). The auxiliary swing plate 27 is pivotally mounted so as to be rotatable about the auxiliary swing shaft 26 extending in the direction perpendicular to the auxiliary swing plate 27, and the skip rail 25 is sandwiched between the auxiliary swing plate 27 and along the skip rail 25. A posture control roller 29 that is rotatable about an auxiliary roller shaft 28 that is parallel to the auxiliary swing shaft 26 so as to roll. Thus, as shown in FIGS. 2 and 4, the inclination angle θ with respect to the horizontal of the line segment OP connecting the center of the base shaft 7 and the center of the auxiliary swing shaft 26 is always kept constant. The carriage 3 can be held horizontally when the carriage 3 travels along the traveling rail 1.

  As shown in FIG. 3, the auxiliary swing plate 27 is attached with a side roller 30 that can roll along the inner surface of the skip rail 25 and regulate the swing of the transport carriage 3 in the width direction.

  Next, the operation of the illustrated example will be described.

  As shown in FIG. 1, in the state where the transport carriage 3 is arranged at the point A, the transported object 2 is loaded on the transport carriage 3, and the drum 14 is driven to rotate by the motor 13 to wind up the rope 4 such as a wire rope. Then, the transport carriage 3 is towed from point A to point B along the traveling rail 1.

  Here, when the transport carriage 3 moves from the vertical portion 1a of the traveling rail 1 to the inclined portion 1b, the base plate 8 is moved so as to follow the curved portion of the traveling rail 1 as indicated by a virtual line in FIG. By rotating about the base shaft 7 and the swing plate 10 rotating about the swing shaft 9, the traveling roller 12 rolls along the traveling rail 1 while sandwiching the traveling rail 1. At the same time, the auxiliary swing plate 27 rotates around the auxiliary swing shaft 26 so as to follow the curved portion of the skip rail 25, so that the posture control roller 29 holds the skip rail 25 along the skip rail 25. It will be rolling.
