Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anti-vibration support device for an engine generator.

[0002]

[Prior art]

 2. Description of the Related Art Some conventional vibration isolating support devices for engine generators are configured as follows, for example, as shown in FIG. That is, the fasteners 4 and 5 are provided at positions separated from the elastic body 1 of two supporting plates 2.3 that sandwich and sandwich the elastic body 1 such as rubber for absorbing vibration. Then, for example, the engine generator main body 6 is fastened to one fastener 4 of the fasteners 4 and 5, and the frame 7 such as the pipe frame 20 is fastened to the other fastener 5 to support each other in a vibration-proof manner. It was made. In the above-described anti-vibration support device, each of the fasteners 4 and 5 is formed in a shape in which the threaded portion of the bolt is projected to both sides, and is tightened with the tightening nuts 21 and 22.

[0003]

[Problems to be solved by the device]

 The above conventional technique has the following problems. When the engine generator main body 6 is fastened to the pedestal 7 such as the pipe frame 20 with the above-mentioned vibration-proof support device, the lower fastener 5 is fastened with the tightening nut 22 from the back side of the pedestal 7. . To assemble the anti-vibration support device, first, the pipe frame 20 is turned over, the fastener 5 is fastened to the pedestal 7 with the tightening nut 22, the anti-vibration support device is previously attached and placed, and then the pipe frame 20 is turned upward. It is necessary to mount the engine generator main body 6 on the anti-vibration support device after the replacement. For this reason, it takes a lot of man-hours to re-install the pipe frame 20 on the front and back sides during the assembling work, resulting in poor workability. An object of the present invention is to reduce the number of steps for assembling a vibration isolation support device.

[0004]

[Means for Solving the Problems]

 The present invention is obtained by adding the following improved structure to the above-mentioned conventional technique in order to achieve the above-mentioned object, as shown in FIG. 1, for example. That is, one fastener 4 of each fastener 4 and 5 is formed by the main body tightening bolt 8, and the other fastener 5 is formed by the opening 9 formed in the support plate 3. Then, a cradle tightening nut 11 that is screwed into the cradle tightening bolt 10 is fixed to the gantry 7 at a position where the engine generator body 6 is supported. Further, the engine generator body 6 is fastened with the body tightening bolt 8 and the body tightening nut 12 screwed to the body tightening bolt 8 and the cradle tightening bolt 10 is inserted into the opening 9 to tighten the cradle. The mount 7 is fastened with the attached nut 11.

[0005]

[Action and effect]

 The present invention is configured as described above, and acts and effects as follows. One fastener 4 of each fastener 4 and 5 is formed by a body tightening bolt 8 and the other fastener 5 is formed by an opening portion 9 opened in the support plate 3, and is mounted on a pedestal 7. The tightening nut 11 is fixed. To mount the anti-vibration support device, first, with the pipe frame 20 facing upward, insert the cradle tightening bolt 10 into the opening 9 and mount the cradle tightening bolt 10 to the cradle 7. Tighten to 11 to attach the vibration isolation support device, and then tighten the engine generator body 6 to the vibration isolation support device with the body tightening bolt 8 and the body tightening nut 12. As a result, it is not necessary to reposition the pipe frame 20 on the front and back sides in the work of assembling the anti-vibration support device, and the number of man-hours for the assembling work can be reduced.
