DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration-isolation gantry which supports an air conditioner outdoor unit or the like in a vibration-isolating manner and can be moved together with the gantry during inspection or repair of the machine.

[0002]

2. Description of the Related Art An anti-vibration pedestal for an outdoor unit or the like has a rectangular lower frame and an upper frame interposed with an anti-vibration material having a spring material or cushion rubber therein and connected with stopper bolts. It is directly fixed to the floor with anchor bolts.
The lower frame must be installed in a place where a considerably large space can be secured in consideration of the work space for inspection of the outdoor unit and replacement of parts. For this reason, a large floor area is required as compared with the size of the outdoor unit main body, and there are various inconveniences such as model selection.

[0003]

SUMMARY OF THE INVENTION The present invention provides an economical vibration-isolation gantry which does not need to secure a work space around the outdoor unit when the outdoor unit is installed. Existing ones can be used.

[0004]

According to the present invention, there is provided an anti-vibration pedestal having a vertical slide guide wall on a substrate and a smooth plate along the guide wall. A pair of fixed support plates arranged and fixed in parallel to each other, and a slide member having an L-shaped cross section is fixed to the bottom of two opposing sides of the rectangular lower frame of the anti-vibration mount and placed on each of the smooth plates A vertical member of the slide member faces the slide guide wall and is bolted at a fixed position, and a stopper member is fixed to an inner edge of the fixed support plate so that a frame side surface of the lower frame abuts. It is. If the outdoor unit and the gantry are relatively large, providing one or more intermediate support plates with only a smooth plate fixed between the two fixed support plates prevents bending of the lower frame and facilitates sliding. This intermediate support plate contacts the lower surface of the frame. The smooth plate is not particularly limited as long as it has excellent lubricity such as a flat plate made of a fluororesin other than a steel plate. The amount of movement of the lower frame relative to the fixed support plate is such that the center of gravity of the entire gantry does not exceed the end of the fixed support plate, and the stopper member is set within this range. Normally, the required movement amount is about 30 cm, which is sufficient, for example, even for a 800 mm x 1300 mm mount.
Since it is 2 (400 mm) or less, there is no danger of falling over and it is safe. Also, the normal total weight is 200kg-300kg,
The worker can move alone. There are various means for expansion and contraction of pipes, cables, and the like connected to the outdoor unit, and since these have no direct relation to the present invention, description thereof will be omitted.

1 to 3, reference numeral 1 denotes an anti-vibration gantry, 2 denotes an upper frame, 3 denotes a lower frame, 4 denotes an anti-vibration material, and 5 denotes stopper bolts provided at four corners. The upper frame and the lower frame have a well-known structure in which frame members are welded to the connection fittings 6 at the four corners. A slide member 10 having an L-shaped cross section is integrally joined to each bottom of the opposite side members 7 and 8 of the lower frame. The joining means may be welding, but in order to facilitate the on-site assembling work, bolts 11 implanted in advance at both ends of the slide member are fixed by nuts 12 through the tongue pieces 6a of the connection fittings. The planting bolt is provided at the center of the frame by inserting a box wrench insertion hole in the frame portion, but is not shown. Reference numeral 15 denotes a fixed support plate, on which a slide guide wall 17 is fixed on a substrate 16 and a synthetic resin smooth plate 18 is screwed 19. The vertical guide wall 17a of the slide guide member and the vertical portion 10a of the slide member 10
And are bolted in a regular home position. Note that the horizontal bent portions 17b and 10b serve as an inclination preventing piece and a dust cover when the gantry is pulled out. Reference numeral 20 denotes a connection bolt, and reference numeral 21 denotes a nut fixed to the slide member. Reference numeral 22 denotes a stopper plate or a projection formed on the substrate 16 by bending or welding.
Abuts against the inner surface of the lower frame to serve as a stopper. 23 is an anchor bolt for fixing the entire support plate to the floor.

[0006] When it is desired to secure a working space on the rear side of the outdoor unit for maintenance or the like, for example, the gantry is pulled out to the front side with all the connection bolts 20 completely removed or completely loosened, and the lower frame is connected to the stopper 22. Abut. In addition, vertical guide wall 1
If a screw hole for the connecting bolt 20 is formed in 7a so that the connecting bolt 20 is screwed, it can be used also as a temporary fixing bolt in the moving state.

FIGS. 5 and 6 show an apparatus in which an outdoor unit 30 is installed close to a wall surface 31 and three surrounding surfaces are surrounded by noise reduction sound absorbing panel frames 32, 33 and 34. Each panel frame of the above three panels is fixed frame 35
A pair of upper and lower U-groove channels 36 are opposed to each other on the outer surface side, and both ends are opened and fixed, and a single panel 38 as shown in FIG. 7 is inserted and connected from each open end 37 in the channel. It is an apparatus which can form a required entrance or a working opening in the frame as needed at any time by removing the single panel in a sliding door manner. This panel frame has an advantage that it can be installed close to the outdoor unit as long as the exhaust of the outdoor unit does not cause a short circuit due to the function described above. In such an installation device, for example, when it is desired to create a working space between the outdoor unit 30 and the wall surface 31, it is only necessary to move the outdoor unit forward, and this moving operation can be performed by one person. In addition, since the moving direction of the gantry of the present invention can be both forward and backward, it can be applied to outdoor units having various installation modes.

[0008]

According to the slide stand of the present invention, the lower frame and the outdoor unit, which have conventionally been fixed, can be moved together, so that there is no need to consider a work space before installation, and installation work is facilitated. In addition, since the conventional vibration proofing stand itself can be used, it is easy to manufacture, and the vibration proofing performance similar to the conventional one is maintained. Further, by sharing with the space-saving muffling panel, the characteristics and advantages of both can be exhibited mutually.
