DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monorail rail support device, and more particularly to a monorail rail support device for moving a device for transporting components along the monorail.

[Prior art]

For example, in an assembly line for a vehicle engine or the like, a transport facility for automatically transporting engine parts to a predetermined position is provided. This transport equipment is, for example, a monorail equipped with an ascending or descending part on a monorail, because it is easy to secure an arrangement space and the workability is good. The monorail traveling device can automatically travel on the upper part, and convey loads such as parts to a predetermined place. The rail support installation of the monorail includes, for example, the following. A hole is drilled in the plate-shaped connecting portion of the cross section I-shaped rail, a mounting plate is fixed to one end of the support arm, and a bolt is passed through the hole formed in the mounting plate and the hole of the plate-shaped connecting portion. A rail support device in which a mounting plate is fixed to an I-shaped cross section by tightening with a nut, and the other end of the support arm is fixed to a support such as a ceiling. A ridge is provided below one side of an upper edge of the cross-sectional I-rail, and a ridge is provided above one side of a lower edge of the cross-section I-rail. On one side of the plate-like connecting portion from the connecting portion with the edge, the inner surface of each ridge, the inner surface of each edge, and the outside of one side of the plate-like connecting portion from the connecting portion. Forming engagement grooves defined by the side surfaces, fixing the inner mounting plate to one end of the support arm, and fitting the upper and lower ends of the inner mounting plate into the upper and lower engagement grooves, respectively. I
An outer mounting plate is applied to the outer side of each ridge of the mold rail, and a bolt passed through a bolt hole formed in the outer mounting plate is screwed into a screw hole formed in the inner mounting plate and tightened. The support arm is fixed to the monorail by sandwiching the upper and lower protrusions between the upper and lower ends of the plate and the upper and lower ends of the outer mounting plate, and the other end of the support arm is fixed to a support such as a ceiling. A rail support device for supporting (for example, see Japanese Utility Model Application Laid-Open No. 59-125505).

[Problems to be solved by the invention]

In the above rail support device, a hole is formed in the cross section 1-type rail itself, and the mounting plate fixed to the support arm is fixed to the plate-shaped connecting portion of the cross section I-rail by tightening means such as bolts and nuts. Therefore, it is necessary to drill holes in the long rails and also drill holes in the mounting plate. There are also certain disadvantages. The support device does not need to make holes in the cross-section I-rail itself, but in order to fit the upper and lower ends of the mounting plate into the upper and lower engagement grooves, When fitting from the end or fitting in the middle of the cross section I-shaped rail, it is necessary to make either one of the upper engaging groove and the lower engaging groove a deep groove. . In either case,
