The fitting portion 1 is removably fitted onto the upper surface of a cable tray receiving member 10 which is protruded into a beam shape. Further, a roller 3 for placing the cable tray on the lower surface is protruded from the upper part of the guide roller main body 2, and the axis of the roller 3 is arranged parallel to the longitudinal direction of the receiving member. A guide surface 4 is provided protruding from the upper end of the main body 2, and the guide surface 4 guides the side surface of the cable tray.

[Example of idea]

Next, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a perspective view of the guide roller of the present invention, and FIG. 2 is an explanatory diagram of its use. Similarly, FIG. 3 is an elevational view of the guide roller in use.

Generally, as shown in FIG. 4, in a cable tray, a large number of trays of a predetermined length are placed in series on a large number of cable tray receiving members 10 protruding from a wall surface at appropriate intervals, and the trays are connected by connecting pieces 11. It is something that

Therefore, the present invention proposes guide rollers as shown in FIG. 1, and a pair of guide rollers are placed on each cable tray receiving member 10 as shown in FIG. It is configured so that it can be moved sequentially in the directions. 1st
As shown in the figure, the lower part of the guide roller main body 2 has a U-shaped cross section, and the opening width thereof is slightly larger than the width of the cable tray receiving member 10, as shown in FIG. Thereby, a fitting portion 1 that is fitted over the receiving member 10 is formed. Further, the upper part of the guide roller main body 2 has rising surfaces facing each other at positions perpendicular to the falling surfaces of the fitting portion 1, and a roller 3 is pivotally attached to each surface. A relatively long rising surface is provided above one of the rollers 3 in a stepped manner, and forms a guide surface 4. Moreover, a very slightly rib-shaped protruding edge is formed above the other roller 3. As shown in FIG. 3, the height of this rib is smaller than the thickness of the side material 6 of the cable tray 5, so that the bottom surface of the cable tray does not come into contact with it. moreover,
The distance between the pair of rollers 3, 3 is such that the space is sufficient to allow the nut 9 to escape as shown in FIG. This is because the guide roller of this embodiment is configured to support the lower surface of the edge of the cable tray 5, so it is necessary to loosely fit the tray assembly nut 9 and screw 8 between both rollers 3, 3. Because there is.

It should be noted that the present invention is of course not limited to the above-described embodiment, and the pair of left and right main guide rollers may be integrated in FIGS. 2 and 3. That is,
A pair of guide rollers may be connected by a connecting member, or a relatively long guide roller body may be formed along the cable tray receiving member 10, and each roller 3 may be provided at both ends of the guide roller body. good. In addition, in order to fix each guide roller to the cable tray receiving member 10, bolt holes previously drilled in the receiving member 10 can be used, and both can be fixed with appropriate fasteners.

[Effect of invention] Next, how to use this embodiment will be explained.

First, depending on the width of the cable tray, a pair of main guide rollers are fitted onto the cable tray receiving member at a distance as shown in FIG. In addition, in order to prevent each guide roller from moving on the cable tray receiving material 10, an appropriate screw is attached to the cable tray receiving material 10.
and the guide roller body 2 are fastened together. In this way, a pair of main guide rollers is attached to each of the cable tray receiving members 10 that are protruded from the wall surface in large numbers. Next, a pair of lifts (not shown) are arranged spaced apart from each other in the cable tray laying direction,
Cable trays of a fixed length are suspended one by one between the lifts and lifted up, and placed between the respective cable tray receiving members via respective guide rollers as shown in FIGS. 2 and 3. The cable tray placed in this way has its side members 6 as shown in Figure 3.
Both side edges of the rollers are guided by the guide surfaces 4 of the respective guide rollers and do not come off the guide rollers. Therefore, the cable tray 5 positioned as shown in FIG. 3 is moved in its longitudinal direction to the leading or trailing end of the laying path. In this way, the cable trays 5 of a fixed length are sequentially placed on the guide rollers, and are sequentially moved in the longitudinal direction to be placed horizontally on each cable tray receiving member 10. Next, the main guide rollers provided on each receiving member 10 are removed, the cable trays 5 are connected to each other in series, and each cable tray 5 is fixed to the receiving member 10 with bolts and nuts to complete the installation work.
