Description

[Detailed description of the invention] This invention relates to a soundproofing device that covers a prime mover such as an electric motor or an engine installed on a common base and a machine driven by the prime mover with a box body provided with a panel.

In general, this type of soundproofing device includes one with a panel structure and one with a frame formed of angles.

The former requires sheet metal processing to provide rigidity to the panels themselves, which increases cost.Also, panels are usually attached to each other with screws, which requires a large number of screws, making assembly complicated. becomes.

Additionally, it is difficult to seal the mounting part of the panel with rubber gaskets or the like to prevent sound from leaking due to the rigidity of the panel.

The latter also has the same problems as the former, such as angle shaping, panel screw fixing, and panel sealability.

The purpose of this invention is to provide a soundproofing device that simplifies sheet metal processing of panels, facilitates disassembly and assembly, and provides reliable sealing.

An embodiment of this invention will be described below, taking as an example a soundproofing device for an electric motor and a machine driven by the electric motor.

An electric motor (not shown) and a machine (not shown) driven by the motor are installed on the common base 1.

Pillars 2 are vertically provided at the corners and any intermediate portions of the common base 1.

The lower part of the vertical beam 3A is inserted into each corner pillar 2, and the lower part of the vertical beam 4 is inserted into the intermediate pillar.

Each of the vertical beams 3A and the horizontal beams 3B and 3C, which together with the vertical beams 3A constitute a frame, have a panel support body U groove W.
and a joint insertion hole H are provided, each beam 3A,
3B and 3C are connected to each other by a joint 5 provided with three shaft portions 5a, 5b, and 5C inserted into joint insertion holes H, respectively.

A U-shaped gasket 15 into which the end edge of the panel forming the box body is inserted is fitted and fixed into the U-groove W of the panel support body of each beam.

The U-shaped gasket 15 is made of an elastic material such as rubber.

6 is the support panel of the electrical box 7, 8°10 is the side panel, 9
11 is a door panel, 11 is a back panel, and 12 is a ceiling panel. Ventilation holes 16 are provided in any panel, such as the side panels 8 and 10, for discharging heat dissipated from the machine to the outside.

The shaft portion of the joint 5 is fixed to each beam by joint mounting bolts 14, and is attached to the support panel 6, door panel 9, side panels 8, 10.
, the lower edge of the back panel 11 is fixed to the common base 1 with panel mounting bolts 13.

According to this invention explained above, the following effects can be obtained.

(1) The panels that form the box body can be easily processed, with almost no bending required, and they are tightly attached and fixed to the beams via U-shaped packing made of elastic material. There is no need to worry about sound leaking through gaps.

Moreover, since the U-shaped gasket absorbs vibrations due to its elasticity, the noise generated by the vibration of the panel is reduced.

(2) There are few screwed parts, and the panel can be inserted into the beam via the U-shaped gasket, making assembly and disassembly easier.

(3) Although the panel itself is a simple plate and lacks rigidity, the beam and panel are interrelated, so the box body has great rigidity.

(4) Since there are fewer bends and drawing parts in the panel, colored iron plates can be used, which reduces the cost of painting or brushing.
