Description

[Detailed explanation of the idea] [Technical field of invention] This invention relates to a motor generator.

[Technical background of the invention and its problems]

The engine generator, which includes a general-purpose engine with an overhead fuel tank and a generator driven by this engine, is housed in a box-shaped outer groove frame, and inside this outer groove frame there are also control boxes, It houses equipment necessary for power generation, such as exhaust mufflers and air cleaners.

However, conventionally, this type of motor generator lacks the ability to store and retain the control box within the outer groove frame, and it also becomes unstable when stacked when storing the generator in the warehouse. The storage space inside the building could not be used effectively.

[Purpose of invention]

This invention focuses on the problems of the above-mentioned conventional technology and aims to improve them by making it possible to store the control box inside the outer groove frame and stably stacking the outer groove frames, thereby reducing the storage space. The purpose of the present invention is to provide a motor generator that can make effective use of.

[Summary of the idea]

In order to achieve the above object, this invention provides a motor generator equipped with a general-purpose engine having an overhead fuel tank and a generator driven by this engine in an outer groove frame, and a bottom frame of the outer groove frame. An engine mount attachment member having a downward opening is provided between them, and the general-purpose engine and generator are mounted on the engine mount attachment member via the engine mount, and between the top frames of the outer groove frame. A control box mounting member is provided to extend over the control box, and the control box is suspended from the mounting member, while a part of the control box mounting member is made to protrude upward to form a protrusion that matches the width of the lower opening of the engine mount mounting member. When the same engine generator is stacked on the upper part of the outer groove frame, the lower opening of the engine mount attachment member of the upper engine generator is connected to the protrusion of the control box attachment member of the lower engine generator. They are engaged and guided for positioning.

[Example of idea]

Embodiments of this invention will be described below with reference to the drawings.

A spark ignition type general-purpose engine 2 having an overhead fuel tank 1 and a rotating magnetic type generator 3 which is directly connected to the output shaft of this engine 2 and driven are constructed by bending pipe material so that the outside forms a box shape. It is installed in the outer groove frame 4 formed as follows. Two engine mount mounting members 6, 6 having a hat-shaped cross section are stretched between the bottom frames 5a, 5a of the outer groove frame 4, and the mounting members 6, 6 have a downward inner dimension a. A lower opening is formed that opens at . Top frames 15, 15 made of pipe material are spanned between the upper frames 5b, 5b of the outer groove frame 4. Rubber engine mounts 16, 16 for absorbing shock and vibration are mounted on engine mount attachment members 6, 6 stretched between the bottom frames 5a, 5a of the outer groove frame 4.
are installed and these engine mounts 16,1
An engine 2 and a generator 3 are attached via 6.

A mounting member 8 of the control box 7 is fixed between the top frames 15, 15 extending over the top of the outer groove frame 4, and the inner dimensions of the engine mount mounting members 6, 6 are attached near the center of the mounting member 8. (Lower opening width) Projecting portions 8a, 8a projecting upward are formed in accordance with a,
When outer groove frames 4 of the same structure are stacked on top of each other, a mounting member is provided on the lower outer groove frame 4 at the lower opening (inner dimension a) of the engine mount attachment member 6 attached to the upper outer groove frame 4. The protruding portions 8a, 8a of 8 are fitted so that the items can be stacked without shifting laterally. In addition,
Projection part 8 of control box mounting member 8
Although a and 8a are formed by bending (cutting and raising) a part of the control box mounting member 8, separate members may be welded and attached to the control box mounting member 8. In addition, protrusions or engagement holes that engage with the protrusions 8a, 8a are provided on the side of the engine mounting members 6, 6, which are stretched between the bottom frames 5a, 5a of the outer groove frame 4, thereby ensuring reliable positioning. You can also.

In addition, in FIGS. 1 to 3, the reference numeral 10 is a muffler.

The output lead 3a of the generator 3 is led to a control box 7, and can be removed by an outlet (not shown). In addition, the control box 7 has a popnut 1 as shown in Fig. 4.
4 is embedded, while the rubber mount 11 is attached to the attachment hole of the control box attachment member 8. A tightening bolt 12 is inserted into the rubber mount 11 via a collar 13, and this tightening bolt 12
is inserted into the pop nut 14 and tightened, so that the control box 7 is elastically suspended from the control box mounting member 8.

Therefore, according to this invention, the outer groove frame 4
If the control box mounting members 8, 8 of the lower outer groove frame 4 are stored on top of each other,
The protruding portion 8a of the engine mount attachment members 6, 6, which are stretched between the bottom frames 5a, 5a of the upper outer groove frame 4, are fitted into the lower openings of the engine mount attachment members 6, 6 and stacked, so that a stable stacked state is obtained. Storage space can be used effectively and the risk of collapse or falling can be prevented.

[Effect of idea]

As explained above, this invention provides a power generator equipped with a general-purpose engine having an overhead fuel tank and a generator driven by this engine in an outer groove frame, between the bottom frames of the outer groove frame. An engine mount attachment member having a downward opening is provided, and the general-purpose engine and the generator are mounted on the engine mount attachment member via the engine mount, and a control member is provided between the top frames of the outer groove frame. A control box mounting member is provided across the engine mount, and the control box is suspended from the mounting member, while a part of the control box mounting member is made to protrude upward to form a protruding portion that matches the width of the lower opening of the engine mount mounting member. When the same engine generator is stacked on top of the outer groove frame, the lower opening of the engine mount attachment member of the upper engine generator engages with the protrusion of the control box attachment member of the lower engine generator. Since the engine generators are aligned and guided for positioning, even if they are stacked on top of each other when storing the engine generators, the protruding parts fit between the engine mount attachment members and can be stacked stably, making effective use of storage space. I can do it.
