Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport equipment used in a hanging transport system for transporting a vehicle body on a fixed route on a ceiling side, for example, in an automobile assembly factory.

[0002]

2. Description of the Related Art Heretofore, as this type of transfer equipment, for example, the structure shown in Japanese Utility Model Application Laid-Open No. 56-151214 has been provided. That is, an upper rail made of an I-shaped member and a pair of left and right lower rails made of a C-shaped member and having open portions opposed to each other are arranged, and these rails are connected at required intervals by a gate-shaped yoke member. As well as
The yoke is connected to the ceiling beam.

According to such a conventional configuration, a rail device composed of each rail or yoke material is provided by connecting the yoke material side to a ceiling beam material. In this case, if the rail is arranged directly below the ceiling beam, the connection on the yoke side can be performed satisfactorily without any hindrance, but the fixed path is set arbitrarily. In some cases, rails are provided so as to intersect the material. At this time, when the pitch between the ceiling beams is long, the rail device is not supported on the ceiling beam side for a certain length, and as a result, the carrier supported and guided by the lower rail is not supported by the ceiling beams. When passing through, the lower rails and the like may be shaken.

For this purpose, conventionally, for example, as shown in FIG. 11, a longitudinal member 81 is disposed between yoke members 80 for connecting an upper rail 78 and a lower rail 79, and both ends of the longitudinal member 81 are provided. Is connected to the yoke member 80 via bolts and nuts 82, and a hanger 83 is provided between the longitudinally intermediate member 81 in the longitudinal direction and the ceiling beam member 88. . Here the hanger 83
Is composed of a holder 84 that can be attached to the ceiling beam 88, a turnbuckle 87 whose both ends are connected to the holder 84 and the front-rear direction member 81 via pins 85, 86, and the like.

[0005]

However, according to the above-mentioned conventional type, the front-rear direction member 81 is required, and the side plate portion of the yoke member 80 is connected to the front-rear direction member 81 to the yoke member 80. The whole becomes expensive and complicated, for example, it is necessary to form holes for bolts, and further, an assembly step for operating the bolts and nuts 82 is required.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a transport facility in which suspension means such as a steady rest can be provided with a simple structure and operation.

[0007]

In order to achieve the above-mentioned object, according to a first aspect of the present invention, there is provided a transporting apparatus in which a plurality of rails are connected in parallel via a yoke member. In the equipment, the yoke member has a gate shape, at least one of a pair of left and right side plates has a locked portion, and a free end of the suspending means from the fixed member side is locked to the locked portion. It is characterized by that.

Therefore, according to the first aspect of the present invention, the suspending means for preventing the lateral shake is disposed between the side plate portion of the yoke member at the most effective position and the fixing member close to the yoke member. Can be set up.

[0009] Further, according to a second aspect of the present invention,
In the above-mentioned configuration of the first aspect, the locked portion is projected from the surface of the side plate portion.

Therefore, according to the second aspect of the present invention, the locked portion can be formed by a bolt or a rivet that is screwed to the side plate. And claim 3 of the present invention.
The above described transport equipment is characterized in that, in the configuration of the above-mentioned claim 1, the locked portion is formed so as to be recessed in the side plate portion.

Therefore, according to the third aspect of the present invention, the locked portion can be formed when the yoke material is formed by, for example, punching or fusing. Further, in the transport equipment according to claim 4 of the present invention, in the configuration according to any one of claims 1 to 3, the rail is supported and guided by a chain-type driving body that applies a moving force to the moving body. The first yoke includes a first rail and a second rail on which the moving body is supported and guided, and the yoke material connects the rails.

Therefore, according to the fourth aspect of the present invention, the first
The rail and the second rail may be connected via a plurality of yoke members. Then, at the time of operation after completion of expected assembly and the like, the moving body can be moved on a fixed route by receiving the moving force of the driving body. At this time, the moving body can move by the support guide by the second rail which is prevented from swinging via the suspending means or the yoke material. Further, the driving body can be moved by the support guide by the first rail which is prevented from swinging through the suspending means or the yoke material.

[0013]
