Description

Detailed Description of the Invention

[0001]

The present invention relates to a vehicle bogie for mounting a vehicle body in a railway vehicle manufacturing factory or the like.
The present invention relates to a traverse method of a vehicle trolley for traversing (transversely moving) between a plurality of parallel rails provided on a floor surface and a technical field related to a vehicle traverser.

[0002]

2. Description of the Related Art In a railway vehicle manufacturing plant or the like, a plurality of rails are provided in parallel on a floor surface, and a railway vehicle (body + vehicle vehicle) mounted on the rail or a vehicle vehicle carrying the vehicle body Is required to be traversed on another rail, so that a traverser that moves in a direction perpendicular to a plurality of parallel rails provided on the floor surface places a conveyed object (railroad vehicle or vehicle bogie) on the floor and traverses it. When the traverser is run at the height of the floor as shown in FIG. 11, the surface of the traverser 1 on which the article 2 is placed is higher than the floor, and the article is moved along the slope 3. It was necessary to pull up (or push up). In addition, as shown in FIG. 12, when the surface of the traverser on which the article is placed is set to be the same as the height of the floor, the article 2 can be moved at the height of the floor and placed on the traverser 1. However, since the traverser 1 needs to be run at a place lower than the floor, the pit 4 is dug on the floor of the factory, and the traverser 1 runs inside the pit. (For example, JP-A-56-120453, JP-A-4-10
No. 8066)

[0003]

However, when the conventional traverser travels at the height of the floor surface, when a conveyed object is pulled up along a slope or when the conveyed object is lowered, an operator directly moves the conveyed object. Work must be performed, such as applying a lifting wire in contact with the object.If the lifting wire is cut or detached while the object moves on a slope, there is a danger that the object may run away. Was accompanied by In addition, if the surface on which the traverser carries the load is the same as the floor, it is safe because there is no work to move the load along the slope, but it is safe to dig a pit in the factory. There was a problem that the surface was divided and workers and work vehicles could not cross the pit.

The present invention solves such a conventional problem, and allows a worker to place a conveyed object on a traverser without touching a vehicle trolley. The object is to enable the traverser to run.

[0005]

Means for Solving the Problems The above object is to hold a vehicle carriage on a rail provided on a floor surface with a grip portion of a telescopic arm provided on a traverser and allow the main frame of the traverser to travel on the rail. The vehicle trolley is lifted up from above the rail by the lifting device installed in the traverser to hold it inside the traverser, and the traverser travels in the direction perpendicular to the rail at the floor level, thereby moving the vehicle trolley to the floor. This is accomplished by traversing between parallel rails on the surface. The above purpose is
A body frame having a space capable of accommodating a vehicle carriage, a telescopic arm that has a grip portion for holding the vehicle carriage and is extendable and retractable, a lifting device for lifting a vehicle carriage on a rail provided on the floor surface, and a floor surface It is achieved by a moving mechanism that travels in a direction orthogonal to the rail at a height of.
