Description

[Detailed Description of the Invention] The present invention relates to a support device for a compressor that reliably absorbs vibrations during operation and transportation of the compressor.

Used as a support device for conventional compressors in 1987-130603
A publication was proposed. That is, as shown in FIG. 1, a stepped bolt 2' consisting of a large diameter part 2'a and a small diameter part 2'b is provided on the frame 1 and projects upward, and the lower part is fitted into the large diameter part 2'a. An elastic body 3, an upper elastic body 4 and a lower elastic body 3 facing the lower elastic body
The coil spring 5 is tensioned between the coil spring 5 and the hollow part 6 of the upper elastic body 4, and is placed on the stepped part 2'c of the bolt 2'. a cylindrical locking member 9' that is brought into contact with 8;
Consisting of a nut 11 that is screwed onto the small diameter portion 2'b and fixes the locking member 9' via a washer 10, and a leg piece 13 of the compressor 12 that is fitted into the groove of the upper elastic body 4. It was hot.

However, in this device, the upper elastic body 4
The gap dimension a' between the inner wall 14' of the hollow part 6 and the cylindrical part 15 of the locking member 9' is extremely small, and this dimension alone can reliably prevent the extreme horizontal vibrations of the compressor 12 during transportation and operation. The upper elastic body 4 abuts against the locking member 9' and is transmitted to the vibrating frame 1 of the compressor, causing frame vibration and noise. Furthermore, since the gap dimension a' is extremely small, precision is required in the arrangement dimensions of the locking member 9' and the upper elastic body 4, making the manufacturing and assembly work difficult. Furthermore, a special stepped bolt 2' is required to fix the locking member 9', resulting in an unavoidable increase in costs.

In view of the above-mentioned drawbacks, the present invention has been developed by simply changing some parts of the conventional equipment and using general-purpose parts, making manufacturing and assembly easy, and reliably absorbing the vibrations of the compressor without increasing the dimensions of the installation equipment. It is intended to.

The structure of the present invention is such that a coil spring is installed between a lower elastic body and an upper elastic body that are respectively inserted into the shaft of a bolt installed upright in the frame, and a coil spring is placed between the two elastic bodies and attached to the shaft of the bolt. A stopper member to be fitted is provided, and the lower surface of the upper elastic body comes into contact with the upper surface of the stopper member to prevent the vertical movement of the upper elastic body. The dimensions are kept large to reliably absorb the vibrations of the compressor.

An embodiment of the present invention will be described below with reference to FIG. Reference numeral 2 denotes a general-purpose bolt that is used as a support column by protruding upward from the frame 1, and this bolt has a lower elastic body 3, a coil spring 5, and an upper elastic body 4 similar to the conventional device shown in FIG. They are designed to be inserted into each other. Reference numeral 9 denotes a stopper member placed on the lower elastic body 3 and fitted into the shaft portion 2a of the bolt 1, and the upper surface of this member is pushed outward in the outer circumferential direction.
A contact surface 16 is formed that contacts the lower surface 8 of the upper elastic body 4 . A nut 11 is screwed onto the bolt 2 and holds a washer 10 for preventing the upper elastic body 4 from coming off.

Therefore, since there is no locking member 9' in the hollow part 6 of the upper elastic body 4 as in the conventional device shown in FIG. 1, a large gap size a between the inner wall 14 of the hollow part 6 and the bolt 2 can be ensured. ing. That is, compressor 1
The upper elastic body 4 is fitted to the leg piece 13 due to the vibration of 2.
Even if it moves in the left-right direction, it can be reliably absorbed by this gap dimension a, and the movement in the vertical direction is restricted by the washer 10 and the stopper member 9.

According to the above embodiment, compared to the conventional device shown in FIG. It is possible to reliably absorb the vibrations of the compressor while keeping it the same as the conventional device.

In terms of workability, assembly is completed by simply fitting the lower elastic body 3, stopper member 9, coil spring 5, and upper elastic body 4 into the bolt 2 vertically installed on the frame 1 in sequence, and then screwing the nut 11. This assembly workability can be improved compared to the conventional device which requires precision in the arrangement dimensions of the locking member 9' and the upper elastic body 4.

As detailed above, the present invention provides a support device for a compressor in which coil springs are arranged between the upper and lower elastic bodies inserted into the support columns of the frame. A stopper member is inserted into the coil spring and placed on the lower elastic body, and the dimension between the upper surface of this member and the lower surface of the upper elastic body is made smaller than the dimension that will contract when the maximum force is applied to the coil spring. The gap between the support column and the hollow portion of the upper elastic body can be increased, and the width of movement of the upper elastic body in the left-right direction can be increased.

Furthermore, the gap size between the support column and the hollow portion of the upper elastic body becomes larger, making it easier to insert the upper elastic body into the support column, thereby improving assembly workability.
