TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension device that suspends a guide rail that guides a transport train from an E-shaped cross-section beam member using an H-beam in order to bridge the guide rail at a predetermined height on a ceiling side.
[0002]
[Prior art]
As described in Japanese Utility Model Laid-Open Publication No. H5-222246, this type of a guide rail suspension device of the type described above uses an upper end of a hanging U-shaped yoke having a lower end coupled to a guide rail. The lower U-shaped yoke is connected to both ends of the lower horizontal overhang of the beam by connecting members, and the lower U-shaped yoke is connected to the lower side of the beam. That type is common. Further, as described in Japanese Utility Model Publication No. 5-40801, the upper end of the hanging U-shaped yoke is connected to a vertical plate portion by a connecting member between a pair of upper and lower horizontal protrusions projecting to one side of the beam member. There is also known a type in which a hanging U-shaped yoke to be connected is connected to a side surface of a beam material.
[0003]
[Problems to be solved by the invention]
Since the hanging U-shaped yoke for hanging the guide rail in a cantilever manner requires a large bending strength, the upper end connected to the beam also needs to have a sufficient height. is there. However, in the suspension device of the type in which the former U-shaped yoke is connected to the lower side of the beam, the upper end of the larger U-shaped yoke for suspension is arranged below the beam. When trying to secure the trolley traveling space of the transport train between the guide rail coupled to the lower end of the hanging U-shaped yoke and the upper end of the hanging U-shaped yoke, The height of the ceiling is low, and the ceiling space cannot be used effectively. Also, in the latter type of suspension device in which the suspension U-shaped yoke is coupled to the side of the beam, it is necessary to form a connection hole in a vertical plate portion of the beam, and the suspension is formed in the length direction of the beam. The mounting position of the character yoke cannot be freely adjusted. In addition, since the entire load acting on the hanging U-shaped yoke is received by the bolts that connect the hanging U-shaped yoke and the vertical plate portion of the beam, a large number of large bolts must be used. And the burden on the mounting work increases.
[0004]

[0012]
An example of a method of suspending the guide rail 2 on the beam 1 using the suspension device having the above-described configuration will be described. As shown in FIG. The upper end of the hanging U-shaped yoke 6 so that the pair of L-shaped members 25, 26 (horizontal plate portions 25a, 26a) abut on the side edges of the lower horizontal overhang portion 1c protruding to one side of the beam material 1. The portion 9 is loosely fitted between a pair of upper and lower horizontal overhangs 1b and 1c protruding to one side of the beam 1 and its lower side 9a is placed on the lower horizontal overhang 1c. By connecting one end of the parallel angle members 23, 24 (horizontal plate portions 23b, 24b) to the lower side of the horizontal plate portions 25a, 26a of the L-shaped members 25, 26 with bolt nuts 28, 29, respectively, The lower horizontal overhang 1c of the material 1 is attached to the lower edge of the upper end 9 of the U-shaped yoke for suspension. Attached and fixed sandwiched between one end of a parallel angle members 23 and 24 (horizontal plate portion 23b, 24b). Then, the holding plate 21 is placed on the other lower horizontal overhang portion 1a of the beam 1 so that the abutment portion 21a abuts on the other end of the parallel angle members 23, 24 (horizontal plate portions 23b, 24b). , And each of the angle members 23, 24 (horizontal plate portions 23b, 24b) and the holding plate 21 are fixed by two bolt nuts 30, 31 adjacent to the side edge of the lower horizontal overhang portion 1a of the beam member 1.

It is also possible to temporarily fix the beam member 1 at a predetermined position in advance with the bolts and nuts 30 and 31.
[0014]
Since the hanging U-shaped yoke 6 attached to the beam 1 as described above sandwiches the beam 1 between the L-shaped members 25 and 26 and the bolt nuts 30 and 31, the bolt nut 28 Even if the rods 31 to 31 are slightly loosened, they do not move in the width direction of the beam 1 and the lower side 9a of the upper end 9 of the U-shaped yoke for suspension is located on the horizontal overhang portion 1c of the beam 1 Therefore, even if the bolt nuts 28 to 31 are loosened to some extent, the hanging U-shaped yoke 6 is hardly inclined.

【The invention's effect】
According to the transport guide rail suspension device of the present invention that can be implemented as described above, the upper end of the suspension U-shaped yoke that requires a sufficient height from the strength side is disposed below the beam. Rather, on the lower side of the beam material, it is possible to form a relatively thin (small height) steel material or the like by simply fixing the hanging U-shaped yoke by frictional force with the beam material. The trolley of the transport train between the guide rail and the beam, compared to the conventional suspension device in which the U-shaped yoke for suspension is connected to the lower side of the beam. The guide rail can be arranged close to the beam while securing space. Therefore, it is possible to increase the height of the guide rail above the floor surface, and to effectively utilize the space on the ceiling side.
[0017]
Further, the entire load acting on the hanging U-shaped yoke can be applied directly from the upper end of the hanging U-shaped yoke to the lower horizontal overhanging portion of the beam member, and one end of the backing material is hung. A large load is not applied to the first connecting member connected to the lower U-shaped yoke or the second connecting member connecting the other end of the patch to the lower horizontal overhang of the beam. Therefore, as compared with the conventional suspension device in which the U-shaped suspension yoke is connected to the side surface of the beam member, it is not necessary to use many large bolts, and the burden on the mounting operation can be reduced.
[0018]
Furthermore, it is used as a first coupling member for coupling one end of the patch to a hanging U-shaped yoke or a second coupling member for coupling the other end of the patch to the lower horizontal overhang of the beam. Even if the fasteners such as bolts and nuts are loosened somewhat, the upper end of the hanging U-shaped yoke is placed on the lower horizontal overhang of the beam material, so that the hanging U-shaped The yoke is unlikely to tilt and the safety is high.
[0019]
According to the second aspect of the present invention, even if the hanging U-shaped yoke is formed of a single thick plate, the hanging U-shaped yoke hangs vertically to the longitudinal direction of the beam. It can be hung in a stable posture. In this case, according to the configuration of the third aspect, it is possible to prevent the pair of parallel angle members from spreading even in a situation where a high load is applied.
