Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 In this invention, the vibration generated during operation from the machinery that accommodates the rotating machine, such as the compressor and cooling fan of the air conditioning machine, is installed while preventing the machinery from falling over due to the excessive amplitude at the time of the earthquake. The present invention relates to an anti-vibration pedestal for air-conditioning machines with the aim of preventing the deterioration of the living environment due to vibration and noise by reducing the transmission of vibrations of machinery and equipment to the floor of a building, etc. .

[0002]

[Prior art]

 Conventionally, this type of vibration isolator for an air conditioner has been made of a square steel pipe provided with a mounting hole for the air conditioner as shown in FIG. 7 and mounted with the air conditioner and fixed with bolts and nuts. Coil springs that reduce the transmission of the vibration of the machine mounting frame b to the lower frame d are installed at several places with the lower frame d. Stopper bolts and hooks attached to the corners serve to limit the excessive amplitude in the vertical and horizontal directions when an earthquake occurs, and to prevent the machine from tipping over via the cushion rubber bush and f. In the lower frame, there are known things that are fixed to the floor of the building by anchor bolts or the like with foundation bolt holes.

[0003]

[Problems to be solved by the invention]

 Of the sizes described in the prior art, the size of the gantry is large, and it is difficult to mass-produce because the size of the gantry varies depending on the model of each air-conditioning machine manufacturer, such as external dimensions, weight, center of gravity, and bolt holes. Yes,

Further, since the machine mounting frame a and the lower frame d are members having strengths corresponding to the weight of the air-conditioning machine to be mounted, the cross-sectional shape of the members becomes large and the mounting surface of the machine becomes higher than the floor surface. As a result, it became an unstable factor.

[0005] In addition, in order to have a strength corresponding to the weight of the air conditioner, the mounting portion of the stop bolt needs to have a solid structure in the above-mentioned portion, and there has been a problem in manufacturing and cost.

In addition, since the position of the center of gravity of the air conditioner differs depending on the model, eight or more anti-vibration devices are attached, the position where the balance can be obtained is calculated, and the position of the anti-vibration device is set. It was necessary to accurately adjust the position and obtain the horizontal position of the machine, which had a problem in terms of workability.

[0007] The present invention has been made in view of such problems of the conventional technology, and an object of the present invention is to combine two or more kinds of components having different sizes. As a result, mass production is possible by simplifying the product and being able to handle a wide variety of air conditioning machines.Also, the mounting position of the air conditioning machines is lowered to improve stability. The mounting position of the air conditioner can be changed by simplifying the corresponding structural parts, and the structure that allows the horizontal position of the machine to be easily determined by adjusting bolts is simplified, easy to handle, performance, price and appearance It also provides an excellent seismic and vibration proof stand for air conditioners.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the vibration isolator for an air conditioning machine in the present invention is configured such that a beam having an anti-vibration mechanism, two beams for mounting the machine, and bolts and nuts for assembling them are elongated grooves. Depending on the combination of parts and the assembly method, it supports the external shape, weight, center of gravity, and mounting holes of various types of air conditioners.

Further, in order to simplify the structure of the portion for performing vibration isolation and to lower the mounting position of the machine, the openings of the lower beam and the upper beam are made of a trough-shaped steel material having a U-shaped cross section. A coil spring and a rubber vibration isolator are accommodated in the lower beam, and the upper beam is placed over the blade of the lower beam, and the mutual blades interfere with each other when an excessive amplitude occurs in the horizontal direction. And the amplitude limiting square hole provided at two or more places in the blade part of the lower beam, and the amplitude limiting hole penetrated with the hole of the blade part of the upper beam at the same position as the center of the square hole. Excessive amplitude is limited by the rod hitting around the amplitude limiting square hole.

The gutter-shaped beam having a substantially U-shaped cross section can respond to an increase in the weight of the air-conditioning machine while limiting the height of the gantry by increasing the thickness of the steel plate.

[0011]

[Action]

 The lower beam is fixed to the floor of a building or the like by anchor bolts or the like by four holes for foundation bolts.

Then, the air conditioner is mounted on the mounting beam fixed to the upper beam by a bolt and a nut in one direction with the base bolt hole of the air conditioner being mounted on the upper beam, and the base bolt of the air conditioner is mounted on the air conditioner mounting groove. Fix the machine with bolts and nuts according to the holes.

The vibration isolating coil spring has a lower portion fixed to a lower beam by bonding or the like with a rubber lower spring retainer. The upper portion of the coil spring has a rubber upper spring retainer and a height adjusting plate. The height of the upper beam can be adjusted by rotating the adjustment bolt, which is fixed to the upper beam via an adjustment bolt.

When the horizontal state of the machine is adjusted, the adjustment is performed by the front and rear, left and right mounting positions of the machine and an adjustment bolt.

The coil spring may be a rubber cylinder or a block.
