[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pump mounting device for mounting and holding a pump for air compression, liquid compression or the like.

[0002]

2. Description of the Related Art Conventionally, a pump mounting device has been used to stably maintain a pump or to prevent transmission of vibration during driving of a pump to the outside. The configuration is as described in Japanese Patent Publication No. 3-324. This conventional pump mounting device will be described with reference to FIG. FIG. 5 is a side view showing a configuration of a conventional pump mounting device 50. As shown in the figure, the conventional pump mounting device 50 has a first,
From the mounting members 53A, 53B of the second pair of upper and lower pumps and the four support members 20A, 20B, 20C, 20D (hereinafter simply abbreviated as 20A to 20D. Other reference numerals are also abbreviated similarly). Be composed.

[0003] Also, the support tools 20A to 20D are composed of four pairs of nuts 21Aa, 21Ab, 21Ba, 21Bb, 21C.
a, 21Cb, 21Da, 21Db (hereinafter simply referred to as 21A
a to 21Db. Other code numbers are abbreviated similarly. ), Bolts (not shown) inserted into the central shaft 4
Elastic members 22Aa to 22D such as rubber having a pair of substantially frustoconical shapes
b, and four coil springs 23 </ b> A to 23 </ b> D.
It is fixed to the mounting members 53A, 53B of the second pair of upper and lower pumps. The four support members 20A to 20D elastically support the pair of upper and lower mounting members 53A and 53B.

Here, as shown in FIG. 1, the mounting member 53A of the first pump 1 is formed in a frame shape so as to be resistant to deformation because the pump 1 is mounted as described later. In addition, four coil springs 23A ~
23D is mounted on each of four pairs of elastic members 22Aa to 22Db so as not to contact the mounting members 53A and 53B of the pump. Also, bolts 61A to 61D, nut 62Aa
Attaching the pump mounting device 50 to the bottom 2 of the pump 1 by attaching rubber dampers 63A to 63D to the four fixtures 60A to 60D composed of I have. With this configuration, transmission of vibration of the pump 1 from the first mounting member 53A to which the pump 1 is mounted to the second mounting member 53B is suppressed.

[0005]

By the way, as described above, in order to prevent the vibration of the pump from being transmitted to the lower mounting member of the second pump, it is mounted on the upper mounting member of the first pump. A fixed distance is provided between the upper and lower mounting members such that the elastic member of the support and the elastic member mounted on the lower mounting member of the second pump do not come into contact with each other even when driving vibration of the pump occurs.

Accordingly, the plurality of holders can prevent the pump from tipping over, and can prevent the coil spring attached to the elastic member from coming off in order to prevent swinging of the interval between the upper and lower mounting members.

According to the pump mounting apparatus of the present invention, the first and second pumps for mounting and fixing the pump body are provided.
It consists of a plurality of attachment members, an elastic member, a fixture, a coil spring and a shaft mounted on the elastic member, and a plurality of holders for elastically holding between the two attachment members. Accordingly, since the mounting members of the two pumps can be elastically supported and elastically held by the plurality of holders, the same effect as described above can be obtained, and the configuration of the pump mounting device can be reduced. Can be lightened, and the manufacturing cost can be reduced.

According to a third aspect of the present invention, there is provided a pump mounting apparatus comprising one mounting member for mounting and fixing a pump body, an elastic member, a fixture, a coil spring and a shaft mounted on the elastic member. The pump body and the mounting member are constituted by a plurality of holders for elastically holding the same.
