Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a power distribution facility in which various power distribution facility devices are mounted and fixed on the same base, and more particularly to a structure of a moving support portion of the power distribution facility.

<Prior art> Conventionally, power distribution equipment in which a switchboard and a transformer are housed in a cubicle is generally transported to the installation site by trailer transportation after the power distribution equipment is mounted and fixed on a single base. Target.

On the other hand, in this base, hanging ears are fixed by welding to the peripheral part for loading and unloading to the trailer, and a jack base for inserting and supporting the jack for position adjustment etc. is also in the peripheral part of the base. It was fixed by welding.

<Problems to be solved by the invention> However, when the hanging ear and the jack stand are fixedly welded to the peripheral portion of the base as described above, the hanging ear and the jack stand are separated from the peripheral portion of the base. Since it projects outwards, it takes up extra space on the trailer's carrier, which limits the width of the distribution installation to a narrower width.

In addition, since the total weight of the power distribution equipment is applied to the mounting parts of the hanging ears and the jack stand when moving, it is necessary to lay a thick beam on the mounting parts of the hanging ears and the jack stand to reinforce the base. There is a problem in that not only the structure of the base is complicated, but also the weight is increased more than necessary.

The present invention has been made in view of the above-mentioned conventional problems, and it is possible to effectively utilize a transportation limit width in transporting a trailer, and to simplify and reduce the weight of a base including a moving support portion. With the goal.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a common mounting portion corresponding to both the hanging ear and the jack stand on the peripheral portion of the base on which the distribution equipment is placed. A suspension ear or a jack stand is detachably attached to this attachment part.

<Operation> According to the present invention, when the entire distribution equipment is loaded and unloaded on the trailer according to the above configuration, the hanging ear is first attached to the common mounting portion provided on the peripheral portion of the base, and the hanging ear such as a crane is hung on the hanging ear. The entire distribution equipment is hung and unloaded. When adjusting the position of the entire power distribution equipment, remove the hanging ears, attach a jack base to the same common mounting part, put a jack under the jack base, lift the entire power distribution equipment, and move it. Make adjustments.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a main part of a power distribution equipment of the present invention.
Is a base in which H-shaped steels are orthogonally combined. A fixing metal fitting 2 having a through hole 2a in the central portion and mounting screw holes 2b, ... On both sides thereof is welded to the outer peripheral side surface of the base 1. Reinforcing plates 3 and 3 are fitted and welded to both sides of the fixing plate 2 so that the reinforcing plate 3 and the fixing plate 2 are joined together.
And form a common mounting portion 4. The hanging ear 5 or the jack base 6 is detachably attached to the common attachment portion 4.

The hanging ear 5 has a rod-shaped portion 5a protruding from a front portion to a rear portion, a plate-shaped portion 5c having through holes 5b, ... Corresponding to the screw holes 2b of the fixing metal fitting 2, and a hanging portion having a collar portion 5d on the front surface. It consists of part 5e.

Further, in the jack base 6, a reinforcing plate 6b is applied between the vertical portion and the horizontal portion of the inverted L-shaped base material 6a so that the abutting portions are respectively attached to the base material 6a.
, And through holes 6c, ... Corresponding to the screw holes 2b of the fixing member 2 are provided on both sides of the vertical portion of the base material 6a.

In order to attach the hanging ear 5 to the common mounting portion 4 of the base 1, as shown in FIG. 2, the rear surface of the plate-shaped portion 5c of the hanging ear 5 is face-contacted with the front surface of the fixing bracket 2 of the mounting portion 4. Screw holes
The through holes 5b, ... are aligned with the 2b, ..., the bolts 7 are inserted and screwed into the screw holes 2b, ..., and fixed.

In this way, after the hanging ear 5 is attached to the mounting portion 4 of the base 1, hanging equipment such as a crane is hung on the hanging portion 5e of the hanging ear 5 to pull up the entire power distribution equipment and load it on the trailer. is there.

Further, in order to attach the jack base 6 to the common mounting portion 4 of the base 1, as shown in FIG. 3, the front surface of the fixing bracket 2 of the mounting portion 4 is brought into contact with the rear surface of the vertical portion of the jack base 6 by surface contact. , Screw holes 2b, ... through holes 6c ,.
Insert it and screw it into the screw holes 2b ..

In this way, after the jack base 6 is attached to the mounting portion 4 of the base 1, a jack is inserted between the horizontal portion of the jack base 6 and the installation surface, and the base 1 is lifted by the jack to adjust the position. To do.

FIG. 4 is a bottom view of the base 1 when the hanging ears 5 are attached to the common attachment portion 4 of the base 1, and as shown in the drawing, between the left and right attachment portions 4 and 4 of the base 1. The reinforcing plate member 8 is installed to strengthen the structure of the base 1.

Further, FIG. 5 shows the entire distribution equipment, and the distribution equipment is
On the base 1, a switchboard 91, an oil-filled transformer 92, and a radiator 93
The electric power distribution equipment and the like are placed and mounted on the cubicle exterior plate 10.

As described above, the hanging ear 5 and the jack stand 6 are detachably attached to the common mounting portion 4 around the circumference of the base 1. Therefore, the hanging ear 5 and the jack stand 6 are hung on the base 1 only when the power distribution equipment is unloaded on the trailer or the like. After mounting the ears 5 and loading and unloading them, and placing them on the trailer, the hanging ears 5 are removed before transportation. Therefore, the transportation limit width of the trailer can be effectively used. When the position of the power distribution equipment is to be adjusted at the site after transportation, the jack base 6 is attached to the common mounting portion 4 and the jack is inserted to adjust the position.

<Effect of the Invention> As described above, according to the present invention, the hanging ear or the jack base is detachably attached to the common attachment portion of the base peripheral portion, so that the transportation limit width can be effectively used when the trailer is transported. Therefore, the width of the entire distribution facility can be set to the full transportation limit width.

Moreover, the number of mounting portions for the hanging ears and the jack stand can be reduced to the necessary minimum, the reinforcing structure for mounting the hanging ears, etc. is simplified, the structure of the base is simplified, and the weight is reduced.
