Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The carriage of the single rail carrier according to the present invention is towed by a motor vehicle and laid on a rail provided on a sloping ground. When loaded, it is necessary to maintain the balance of the carrier truck and improve safety.

Therefore, in the present invention, an auxiliary roller case is provided so as to project laterally from the gantry of the carrier.
The auxiliary roller case floats up and down by a link pivotally supported by a gantry, and an auxiliary roller that comes into contact with an auxiliary rail is provided inside the case. The auxiliary roller is supported by an elastic body and is moved up and down. This paper proposes a carrier truck that can keep the balance of the mounting table by a floating roller that follows the roller and supports the lower surface of the mounting table.

2. Description of the Related Art An apparatus that slides an auxiliary rail on an auxiliary rail through an elastic body from a frame that supports a roller portion of a main rail, or a device that supports a lower surface of a mounting table from the frame via an elastic body is known. Are known.

[0004] In the case of a single rail carrier, since it travels on a rail having a left-right curve and a vertical curve, a certain degree of freedom is required for the gantry and the mounting table. With this degree of freedom, it is possible to run smoothly and stably without damaging the rails or the like. For this reason, the gantry and its mounting table are configured to be rotatable back and forth and left and right, and the gantry is also configured to be slidable up and down. For this reason, there is a drawback in that the mounting table is likely to be tilted to the left and right with respect to the traveling direction of the rail due to an unbalanced load of the load.

Further, since the rails form a curved line because they are installed on a sloping ground, the upper surface of the main rail sandwiched by the upper and lower rollers may be installed horizontally in order to keep the carrier horizontal during installation. Although it is necessary, the construction is a complicated work and is not easy and accurate at present.

Therefore, when the main rail is not installed horizontally, the pedestal of the carrier truck falls down along the main rail, and when the mounting platform is supported by this inclined platform. Since the mounting table tilts due to the fall of the mounting table, it becomes impossible to maintain a horizontal posture, which causes a problem that stable traveling cannot be performed. As a result of this problem, the auxiliary roller provided on the frame tries to raise the frame along the rail of the auxiliary rail, but if the horizontal accuracy of the main rail is insufficient, the frame presses the compression spring of the auxiliary roller. You can't just level it. Therefore, the mounting table provided on the gantry that cannot be horizontal is also not horizontally held, and there is a risk of load collapse.

Further, there is one in which an auxiliary roller is provided on the mounting table provided on the platform of the carrier vehicle so that it can contact the auxiliary rail at any time. In this case, the platform and the mounting table are Since it is rotatable, there is a problem that the auxiliary roller derails from the auxiliary rail at the curved portion of the rail, causing a deviation between the advancing direction of the gantry and the advancing direction of the mounting table.

BEST MODE FOR CARRYING OUT THE INVENTION A link pivotally supported on a frame provided with a roller portion of a main rail is provided, an auxiliary roller case is provided by an elastic body by this link, and an auxiliary roller provided in the case assists. I try to touch the rail. In this way, the link supports the auxiliary roller in the auxiliary roller case through the elastic body. The auxiliary roller support portion is fixed close to the rotating portion of the gantry, and there is no risk that the auxiliary roller derails from the auxiliary rail. The link causes the auxiliary roller to move up and down, and the floating roller can support the lower surface of the mounting table to easily keep the mounting table in balance by following the vertical movement.

[0017]

As an effect of the present invention, by providing the auxiliary roller and the floating roller on the mount via the link,
The following technical effects will be exhibited.

When installing the rail, it is easy to keep the heights of the main rail and the auxiliary rail constant and to make the left and right auxiliary rails almost horizontal. Therefore, even if the main rail of the rail is tilted, Attempts to incline along the fall of the rail, but the compression spring supporting the auxiliary roller is compressed,
This force tries to raise the gantry. At this time, the floating roller, which moves following the auxiliary roller, moves above the lower portion of the mounting table to raise the mounting table. As a result, the mounting table can travel substantially horizontally along the auxiliary rails provided on the left and right sides of the main rail even if the platform is tilted.

Therefore, according to the effect of the present invention in a single rail carrier, it is possible to provide a carrier truck which can stably run even if a long object or a heavy object is loaded.
