DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail structure of a monorail type transfer device used in factories and construction sites.

[0002]

2. Description of the Related Art In a conventional monorail type transfer apparatus, a traveling rail is mounted, a lifting machine is suspended on a trolley traveling on the rail, and a load is traveled in a suspended state.

[0003]

In the conventional apparatus,
When changing the transport route, it is common to rebuild the rails, or to mount the rails on all the routes to be changed in advance and change the route using a switching device at the place where the route is changed. Has been adopted.

[0004] The reworking of the former rail mounting requires a lot of time and labor, and the route is fixed.

[0005] The latter method, in which rails are mounted on all the routes, increases equipment costs and is not suitable except when the routes are changed very frequently.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rail structure of a monorail type transfer device in which a route can be easily and arbitrarily changed and equipment cost is reduced.

[0007]

According to the present invention, end metal pieces at both ends, a flexible vertical strip connecting these metal pieces, and a long plate wound around the strip are provided. It consists of a spiral tube formed by turning.

[0008]

In the rail structure of the monorail type transport device configured as described above, when changing the route of the rail, if the strip is bent in the horizontal direction according to the shape of the path, the strip becomes longer. The spiral tube formed by winding
Deformed along the curvature of the strip.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, a traveling rail indicated generally by reference numeral 1 is mounted between a floor 6 and a ceiling 7 of a factory in the illustrated example by a plurality of pairs of columns 2 and beams 3. A trolley indicated generally by reference numeral 4 is suspended from the traveling rail 1. And in the middle of the running rail 1,
A flexible rail generally indicated by reference numeral 10 is provided which bends at a substantially right angle indicated by a hatched portion.

In FIGS. 4 and 5, circular end fittings 11 are provided at both ends of the flexible rail 10, respectively. These two ends 11, 11 are connected by a flexible strip 12 fixed on the vertical diameter. A long plate 14 is wound around the band plate 12 to form the spiral tube 1.
3 are formed, and both ends of the helical tube 13 are not dropped off by the metal fittings 11 at both ends, and may be fixed to the metal fittings. The trolley wheel 5 of the trolley 4 is supported on the upper outer periphery of the spiral tube 13.

The processing of the flexible rail 10 is shown in FIG.
As shown in FIG. 5, a long plate 14 is spirally wound around a mandrel (not shown) to form a spiral tube 13. Next, a strip 12 having an end fitting 11 attached to one end thereof is inserted into the spiral tube 13, and the end fitting 11 is attached to the other end of the strip 12. This attachment may be made, for example, by welding or bolting.

Next, the operation will be described.

When the path is changed by the flexible rail 10, as shown in FIG. 7, the strip 12 is bent in the horizontal direction so as to match the radius of curvature B of the path. Then, the spiral tube 13 into which the band plate 12 is inserted is deformed by bending its outer shape along the radius of curvature B of the band plate 12 due to its own spring property.

[0015]

Since the present invention is configured as described above, the shape can be easily and arbitrarily changed, and the equipment cost can be reduced.
