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, as shown in FIG. 8, for example, 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 hanging tool 83
A holding tool 84 that can be attached to the ceiling beam member 88 and a turnbuckle 87 whose both ends are connected to the holding tool 84 and the front-rear direction member 81 via pins 85 and 86 are provided.

[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 transfer facility in which ancillary components such as a steady rest can be arranged 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. The facility is characterized in that the yoke member has a gate shape and inwardly protruding portions are formed on opposing surfaces of the pair of left and right side plate portions.

Therefore, according to the first aspect of the present invention, the yoke member for connecting the plurality of rails can use the protrusions to lock the accessory components and support the load, and can arrange the accessory components. The yoke material is obtained by, for example, stamping or fusing.

[0009] Further, according to a second aspect of the present invention,
In the above configuration, the free end of the suspension means from the side of the ceiling beam is locked to the projection from below.

Therefore, according to the second aspect of the present invention, the suspending means for preventing lateral vibration is disposed between the yoke member at the most effective position and the ceiling beam member near the yoke member. obtain.

According to a third aspect of the present invention, there is provided the transporting apparatus according to the first or second aspect, wherein the yoke member has a supporting means for supporting a long object disposed along the rail. The support means has a locking portion which is locked to the projection from above and below.

Therefore, according to the third aspect of the present invention, the locking means is locked to the projection to prevent the support means attached to the yoke material from shifting downward due to the load of a long object. By doing so, you can prevent it.

According to a fourth aspect of the present invention, in the transport equipment according to any one of the first to third aspects, the rail is supported by a chain-type driving body that applies a moving force to the moving body. The first yoke member comprises a first rail to be guided and a second rail to support and guide the moving body, and the yoke member 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.
