Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compressor replacement jig used for a heat source unit installed in a machine room such as a tenant building.

[0002]

2. Description of the Related Art Generally, a heat source unit that constitutes a building air conditioner is arranged in a machine room. In recent years, however, in a tenant building, in order to efficiently use the space in the building to increase the rentable ratio, There is a tendency to design the space as small as possible. Therefore, reducing the height of the heat source unit and mounting the heat source units in, for example, two stages is a great merit of the heat source unit.

[0003]

By the way, when the heat source units are stacked in two stages, two or more people are required to replace the compressor housed in the heat source unit, and the compressor falls. Due to the above reasons, there is a danger in replacing the compressor.

It is an object of the present invention to provide a compressor replacement jig which enables two people to replace the compressor safely and in a short time.

[0005]

In order to achieve the above-mentioned object, the present invention has a suspension bolt hole which is stacked in a plurality of stages, each of which is used for connecting each other, and a compressor, a heat exchanger, And the refrigeration cycle parts connecting them are housed in the casing, and in the compressor replacement jig in the heat source unit in which the compressor lower space is formed in the lower part of the compressor, the rollable spherical roller and the vertical movement A jack device having a free compressor support base, which is inserted into a lower space of the compressor and supports and moves the compressor, and a drive source which is connected to the jack part and which drives the jack part. A pulley attachment fitting fixed to the heat source unit located at the uppermost stage by using the hanging bolt hole, and a pulley assembly attached to the pulley attachment fitting to hang the compressor.

[0006] In this way, the present invention is to enable the replacement work of the compressor to be performed safely and in a short time by two people.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows an embodiment of the present invention. Reference numerals 1 and 2 in the drawing are heat source units constituting, for example, a building air conditioner facility. Each of the heat source units 1 and 2 has a compressor 5 housed in a rectangular box-shaped casing 3 and 4 as shown in FIG. The compressor 5 is fixed at a floating position with respect to the inner bottom surface 6 of the casing 4, and a lower space 7 is formed at the lower part of the compressor 5.

Further, a compressor 5 is provided in each of the casings 3 and 4.
Besides, a heat exchanger, a refrigeration cycle component for connecting the compressor and the heat exchanger, and the like are housed, and these devices are schematically shown by a chain double-dashed line 8 in FIG.

Also, the outer bottom surfaces 9 of the casings 3 and 4,
9 is provided with connecting metal fittings 10 and 10 having a U-shaped cross section. Further, the ceiling portions 11, 11 of the casings 3, 4 are
2 are provided with bolt holes 12, ... As shown in FIG. One of the heat source units 1 and 2 is placed on the base 13, and the other heat source unit 2 is stacked on the heat source unit 1. The heat source units 1 and 2 are bolts 14 screwed together while sandwiching the metal fittings 10 and 10.
Are fixed to the base 13 and the lower heat source unit 2, respectively.

Reference numeral 15 in FIG. 1 denotes a jack device. As shown in FIGS. 3 to 5, the jack device 15 includes a jack portion 16, a hydraulic pump 17, and a hose 18 which is flexible and connects the jack portion 16 and the hydraulic pump 17. ing.

Of these, as shown in FIGS. 4 and 5, the jack portion 16 includes a rectangular jack main body 19 and a spherical roller 20 provided at the lower portion of the jack main body 19.
And a disk-shaped compressor support base 21 provided on the upper portion of the jack body 19.

The spherical roller 20 is arranged at each of the four corners of the jack body 19, and
, And is freely held while being held by the roller holders 22 ... Which protrude from the jack body 18. Further, the compressor support base 21 is connected to an elevating mechanism portion 23 located at the center of the jack body 19 and is vertically displaced via the elevating mechanism portion 23.

That is, the jack device 15 is a spherical roller 2
It moves while rolling 0 ... and is guided to an arbitrary position.
Further, when the hydraulic pump 17 is driven, the hydraulic pressure in the elevating mechanism 23 is adjusted via the hose 18, and the compressor support 21 moves up and down according to the driving force of the hydraulic pump 17.

Further, in FIG. 1, reference numeral 24 is a pulley attachment fitting, and reference numeral 25 is a pulley device.

As shown in FIG. 2, the pulley attachment fittings 24 are two L-shaped fittings arranged along the side edges of the outer ceiling surface 26 of the upper heat source unit 2 and protruding from the heat source unit 2. 27 and 27, and a round metal fitting 28 erected on the projecting ends of the L-shaped metal fittings 27, 27.

The L-shaped metal fittings 27, 27 are provided on the outer ceiling surface 26.
The through holes are provided in a positional relationship corresponding to the bolt holes 12 ... Opened at the same time, and one piece thereof is arranged along the outer ceiling surface 26 of the heat source unit 2. And the L-shaped metal fitting 27,
27 is pressed and fixed to the heat source unit 2 by the bolts 14 screwed into the bolt holes 12.

Further, both ends of the round metal fitting 28 in the axial direction are passed through the tips of the L-shaped metal fittings 27, 27, and both end portions in the axial direction are supported by the L-shaped metal fittings 27, 27.

The pulley device 25 has a main body side hook 29 and automatically pulls out and winds up the wire 30.
1 and a pulley 33 held by a wire 30 and having a pulley-side hook 32. Then, in the pulley device 25, the main body side hook 29 is hooked on the round metal fitting 28 to be attached to the pulley attachment fitting 24.
Drop 2 downwards.

The jack device 15 and the pulley mounting bracket 2 described above.
4 and the pulley device 25 constitute a compressor exchange jig 34, and the compressor 5 is exchanged using this compressor exchange jig 34.

That is, the connecting pipe of the compressor 5 housed in the upper heat source unit 2 is removed from the compressor 5, and the jack portion 16 of the jack device 15 is sent to the lower space 7 below the compressor 5. Enter. Further, the compressor 5 is released from the casing 3, and the hydraulic pump 17 is driven to raise the compressor support base 21. And the compressor 5
Is placed on the compressor support 21 and then the jack portion 16
Is pulled out by the worker with the compressor 5 still mounted, and moves to the front of the worker.

Further, as shown in FIG. 2, a suspension chain 36 is stretched over the projections 35, 35 of the compressor 5 to form a chain.
The pulley side hook 32 of the pulley device 25 is hooked on the hook 36. Then, the pulley device 25 is driven, the wire 30 is wound up, and the pulley 33 rises. Then, the compressor 5 is pulled and separated from the jack device 15, and is suspended while applying its own weight to the pulley device 25. Then, after this, the wire 30 is paid out, the pulley 33 is lowered, and the compressor 5
Is dropped on the ground, for example.

When the compressor 5 is incorporated in the heat source unit 2, the above-mentioned work is performed in the reverse order.

That is, by using the compressor exchange jig as described above, it is not necessary to manually lift the compressor 5. Moreover, since the compressor 5 is suspended by the pulley device 25,
The compressor 5 is not dropped and the work is safe. Furthermore, since it is not necessary to manually lift the compressor 5, two people can replace the compressor 5 in a short time.

The present invention can be variously modified without departing from the scope of the invention.
