Description

[Detailed Description of the Invention] This invention relates to an improvement of a vibrating body mounting device in which the vibrating body and the elastic body are mounted on a table using bolts via an elastic body.

Conventionally, as this type of apparatus, there have been those shown in FIGS. 1 and 2. Figure 1 shows the vibrating body in operation; in the figure, 1 is the mounting foot of the vibrating body (not shown) such as a compressor, and 2 is the vibrating body (not shown).
A vibration isolating spring 3 is used to fix the mounting foot 1 of the vibrating body (not shown), and a base plate having a bolt insertion hole 3a is used. 5 is a bolt fixed to the base plate 3 by welding, 6 is a washer, and 7 is a spacer made of hard rubber etc. to prevent vibration when starting and stopping the vibrating body (not shown). , is a nut attached to the washer 6 with a gap of about 2 to 3 mm, as shown in Fig. 2, to prevent vibration of the vibrating body (not shown) during transportation of the vibrating body (not shown). The mounting leg 1 is tightened until it comes into contact with the spacer 4.

In the vibrating body mounting device configured as above,
Nut 7 tightened to prevent vibration during transportation
It is necessary to loosen the nut 7 at startup and adjust the gap with the washer 6 to 2 to 3 mm as shown in Fig. The vibrating body (not shown) vibrates abnormally due to looseness or insufficient loosening, and the vibrating body (not shown)
There were drawbacks such as malfunctions.

This invention attempts to eliminate the above-mentioned drawbacks by providing a collar having an internal cavity and a nut for tightening the collar as a fixing device during transportation.

An embodiment of this invention will be described below based on the drawings. Figure 3 shows the state at the time of transportation, and in the same figure, 8 is a collar with a cavity A in which the nut 7 and washer 6 can be stored, and the upper part has a threaded part 8a for mounting. , the lower end is adapted to come into contact with a mounting foot 1 of a vibrating body (not shown). In addition, nut 7 is with collar 8 removed,
The gap with the washer 6 indicated by the dashed line in the figure is adjusted to 2 to 3 mm. In other words, as a mounting device for the vibrating body, a collar 8 with a cavity that can accommodate a nut 7 and a washer 6, and a mounting screw part 8a on the top is provided for fixation during transportation, so it is easy to start operation at the site. Sometimes it is only necessary to remove the collar 8.

As described above, this invention has the effect of eliminating the conventional drawbacks such as failure of the vibrating body due to abnormal vibration of the vibrating body due to forgetting to loosen or insufficient loosening of the nut tightened during transportation. play.

In the above embodiment, a case was described in which the collar 8 was divided into a threaded part 8a such as a nut, but as shown in FIG. Good as a shape,
Further, the same effect can be obtained even when the sheet metal is bent and tightened with a nut as shown in FIG.

[Brief explanation of the drawing]

FIG. 1 and FIG. 2 are cross-sectional views showing the state of the conventional mounting device during operation and transportation, respectively;
FIG. 3 is a sectional view showing a mounting device which is an embodiment of this invention, and shows the state during transportation. 4 and 5 are perspective views showing other embodiments of this invention. In the figure, 1 is a mounting foot of the vibrating body, 5 is a bolt, 7 is a nut, 8 is a collar, and 8a is a mounting thread.
In addition, in the figures, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] A vibration isolating elastic body is interposed between the mounting foot of the vibrating body and the base plate, a bolt is inserted through these, and a first nut is screwed into the threaded part of the bolt,
