Device unit). Legs are attached to these device units, and holes formed in the legs and holes formed in the gantry 2 are connected to each other with bolts and nuts and fixed to the gantry 2. The equipment unit is welded or flared to an evaporator or a condenser (neither is shown) via a copper pipe to form a refrigeration cycle.

Reference numeral 8 denotes a support frame. The supporting frame 8 is composed of the pillar 9 and the beam 1
0, which is formed by bending a plate-like sheet metal into a U-shape that opens downward. The column 9 of the support frame 8 has a slightly higher dimension than the component having the highest height among the components placed on the gantry 2. A beam 10 is formed between the columns 9 of the support frame 8. A screw hole 11 is formed in a lower portion of the column 9, and the screw hole 11 and a hole formed in a side surface of the gantry 2 are connected and fixed by screws. As shown in FIG. 1, the column 9 is vertically set substantially at the center of the side surface of the gantry 2. The beam 10 is provided across the center of the gantry 2 in parallel.

Reference numeral 12 denotes a compressor connector for connecting the support frame beam 10 and the compressor 3. A plate-shaped sheet metal is bent and formed into a crank shape and includes an upper piece 13, a vertical piece 14, and a lower piece 15. The upper piece 13 of the compressor coupler 12 has two holes for screw attachment, and the lower piece 15 has one hole. The upper piece 13 of the compressor connector 12 is connected to the beam 10 of the support frame 8.
It is screwed and fixed in the hole made in the hole. Compressor coupler 1
The hole of the lower piece 15 of the second piece 2 is loosely fitted to a bolt 16 protruding upward from the upper center of the compressor 3. By tightening the nut 17 from above the bolt 16 of the compressor 3, the lower piece 15 of the compressor coupler 12 is fixed between the upper surface of the compressor 3 and the nut 17. The nut 17 is tightened when the refrigeration apparatus 1 is transported, and prevents shaking and vibration during transport. When the transport of the refrigeration apparatus 1 is completed, the nut 17 is removed, and during operation, the vibration of the compressor 3 is received by the outer periphery of the bolt 16 of the compressor 3 and the inside of the hole in the lower piece of the compressor coupler 12. Vibrations having a small amplitude remain as they are, and vibrations having a large amplitude are suppressed.

Numeral 18 denotes an electrical box connector for connecting the beam 10 of the support frame to the electrical box 7. It is formed of a flat plate-shaped sheet metal. Two holes for screw mounting are formed at both ends of the electrical box connector 18 respectively. One end of the electrical box connector 18 is screwed and fixed to a hole formed in the beam 10 of the support frame. The other end is screwed and fixed to the upper hole of the electrical box 7. During transport or operation, the electrical box connector 18 prevents shaking and vibration.

Reference numeral 19 denotes a receiver coupling for connecting the beam 10 of the support frame 8 and the refrigerant receiver 5. A plate-shaped sheet metal is bent and formed in an inverted L-shape. The upper piece 2 of the receiver coupler 19

The vertical piece 21 of the liquid receiver coupling 19 is fastened and fixed to a hole of a vertical piece protruding upward from the upper part of the refrigerant liquid receiver 5 with a bolt and a nut. Prevents shaking and vibration during transport and operation.

[0015] In the equipment unit, high-height equipment is difficult to withstand external force during transportation or operation when fixed only at the lower part, and copper pipes connected to these equipment must be connected due to large shaking and vibration. It may cause damage and also cause a failure of the equipment itself constituting the equipment unit. Thus, in the equipment unit,
By fixing the upper part of the tall device unit to the beam 10 of the support frame 8, the mechanical strength is increased, and the vibration and vibration of the device are suppressed, and the adverse effects due to this can be reduced.

The refrigerating apparatus 1 of the present invention is a simple unit in which an equipment unit is simply attached to a gantry, but sometimes an exterior plate 22 is attached to the refrigerating apparatus 1 at the request of a customer. When mounting the exterior plate 22 in a box shape, the holes formed in the support frame 8 and the holes formed in the exterior plate 20 are aligned and screwed. Thereafter, the holes formed in the side edges of the gantry 2 and the holes formed in the exterior plate 22 are aligned and screwed.
At first, the exterior plate 22 is fixed to the support frame 8, so that the positioning when screwing to the side edge of the gantry 2 is simplified. Further, since the exterior plate 22 is fixed in the vertical direction and the horizontal direction between the column 9 of the support frame 8 and the side edge of the gantry 2, the strength is increased as compared with the case without the exterior plate 22, and it is more resistant to shaking and vibration.

FIG. 3 is a plan view showing a refrigeration apparatus according to a second embodiment of the present invention. FIG. 4 is a front view of the same. In FIGS. 3 and 4, the same elements as those in FIGS. 1 and 2 are denoted by the same reference numerals, and description thereof will be omitted.

In the second embodiment, as shown in FIG.
A column 9 of a support frame 8 composed of a beam and a beam 10 is erected vertically on the left side and the right side of the gantry 2, and the beam 10 is bridged over the column 9. Hole 1 opened in the lower part of pillar 9 of support frame 8
1 and a hole formed in the side surface of the gantry 2 are connected and fixed with screws. As shown in FIG. 4, the beam 10 extends linearly across the gantry 2 diagonally, and is disposed substantially above the compressor 3 and the refrigerant receiver 5.

Reference numeral 23 denotes a compressor connector having a square U-shape. Two screw holes are formed in both end pieces 24 of the compressor connector 23, and one screw hole is formed in the bottom 25. The holes of both end pieces 24 of the compressor connector 23 are screwed through the holes of the beam 10 to be fixed by tightening. A bolt 16 extending upward from the upper center of the compressor 3 is loosely fitted into the hole of the bottom side 25. In this way, the sway and vibration generated during transportation and operation are suppressed by the bolts and nuts for fixing the lower part and the compressor connecting member 23 at the upper part, and large sway and vibration of the compressor 3 are suppressed.

The receiver coupling 26 of the refrigerant receiver 5 has an inverted L
It is shaped like a letter. Two screw holes are formed in the upper side 27 of the liquid receiver coupler 26 of the refrigerant liquid receiver 5, and holes are also formed in the vertical side 28. In the hole on the upper side of the receiver connecting fitting 26, a screw is fixed from above the hole of the beam 10. Two vertical pieces are provided vertically from the upper center of the refrigerant receiver 5, and each of the two vertical pieces is provided with one hole. The hole of one of the vertical pieces and the hole on the vertical side 28 of the receiver connecting fitting 26 are fixed with bolts and nuts. In this way, the sway and vibrations that occur during transport and operation are suppressed by the bolts and nuts that fix the lower part and the upper liquid receiver coupling hardware 26, and the refrigerant liquid receiver 5 is prevented from being largely shaken.

In the refrigeration system 1 of the second embodiment, the beam 10 of the support frame 8 fixes almost directly above the two higher components in the equipment unit, so that vibrations and vibrations applied to the components are reduced. Since it is suppressed at the center of the plate material of the support frame, it is easy to avoid torsional force on the beam 10, and the load on the beam 10 is reduced compared to the first embodiment, and the load is applied to the fixed lower portion of the support frame 8. Power is also reduced.

Although the present invention has been described based on the embodiment, the present invention is not limited to this. In the present embodiment, the pillars of the support frame are provided on the opposing side surfaces of the gantry 2, but may be provided on the orthogonal side surfaces. The support frame is 1
There may be more than one. Further, although the connecting member is formed of metal, it is not necessary to use metal as long as it has a certain strength, such as wood or resin.

[0023]

According to the first aspect of the present invention, a device in which only the lower portion of the device unit is fixed is also fixed or supported from the upper portion, thereby suppressing large fluctuations and vibrations caused by a high device. The copper pipe connected thereto, the copper pipe connection part and other parts can be less damaged. In addition, it is possible to reduce the loosening of the screw due to the vibration and the cause of the failure of the refrigerating device caused by the loosening.

According to the second aspect of the present invention, by providing the pillar of the support frame fixed to the gantry and the screw hole on the side surface of the gantry, when attaching the exterior plate of the box to the refrigerator,
The outer plate can be fixed to the outer periphery of the lower portion and the upper and middle portions of the side surface by screws, so that the toughness of the outer plate is improved. In addition, since the gantry, the support frame, and the exterior plate are connected and fixed to each other, the support frame is reinforced, and the vibration and vibration of components connected thereto are suppressed, and the vibration isolation structure is improved.
