Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to stack a plurality of working machines in a stack when storing an engine-driven generator installed in a pipe frame structure, and to vibrate from the engine during operation. The present invention relates to a pipe-shaped frame structure of an engine-driven generator, which is intended to prevent the sliding movement of these machine main bodies.

[0002]

2. Description of the Related Art In the case of a generator driven by an engine, which is required to be used at a construction site, etc., it is stored side by side on the floor of a storage warehouse from the end of construction work until the decision of the next construction work. Has been done. However, in recent years, due to the problem of space in storage warehouses, efficient use of these spaces and improvement or improvement of equipment have been required.For example, in the case of medium- or large-sized engine-driven generators, there is a problem of strength. A box-type structure that copes with the reinforcement of the frame body or the like enables stacking and placing, and the correspondence is performed.

On the other hand, in the case of a small engine-driven generator as an example, many of them usually adopt a pipe frame structure for the purpose of weight reduction. However, such a frame structure of the pipe frame structure is used. Therefore, it is required to have a structure in which the stacking form can be handled as much as possible.

[0004]

As a structure of the outer frame of a small engine-driven generator that employs a pipe frame structure, Japanese Patent Application No. 55-120946 (Japanese Utility Model Application No. 57-145) is available.
No. 255), the structure of the outer frame body disclosed in Japanese Utility Model Application No. 55-120946 is such that the upper pipe frame stacked on the outer edge portion of the pipe frame has the lower position. When placed on the pipe frame, the end of the connecting member provided at the bottom of the upper pipe frame projects the end that engages with the pipe diameter of the lower pipe frame to form an arc surface. The solution is achieved by doing.

In the outer frame structure of the pipe frame having such a structure, when lateral rubbing (horizontal direction) occurs, the pipe frame enables regulation of lateral rubbing. When rubbing in the direction occurs, there is no means to regulate the movement of the rubbing, so there is little problem in stacking management in the storage warehouse unless there is extreme vibration, but Accidents such as load collapse may occur when stacking and transporting by trucks.

On the other hand, in the case of adopting a multi-pole magnet type high frequency generator as the generator of the engine-driven generator from the aspect of size and weight reduction, the generator becomes extremely small with respect to the engine,
The weight balance of the entire machine is biased toward the engine side. Therefore, if such a generator with a poor weight balance is stacked and placed, a load collapse accident will occur during truck transportation, and if the engine is operated at a construction site, as described above. There is also a problem of gradually moving due to the vibration of.

Therefore, the present invention has been made in order to solve such a drawback, and the engine generators having a pipe frame structure are stacked and stored in a storage warehouse, or stacked and moved by a truck or the like. Even if the center of gravity of the stacked engine generators is in an unbalanced state, the engine-driven power generation located in the lower stage at the engagement part formed on both sides of each base member welded to the pipe frame. The pipe material welded to the top of the pipe frame of the machine regulates the movement of the engine-driven generator, and when the multi-stage stacking is performed, the engine-driven generator is rotated 180 degrees. It can be rotated and placed alternately,
Furthermore, an object of the present invention is to provide a pipe-shaped frame structure for an engine-driven working machine, in which elastic members attached to the respective end portions of the base member can prevent movement of the machine body due to engine vibration. To do.

[0008]

In order to achieve such an object, the present invention is characterized by a pipe-shaped frame structure of an engine-driven generator in which an engine and a generator are housed in a pipe-shaped frame. The pipe-shaped frame is welded and fixed to the pipe frame and the top of the pipe frame. 2
A pipe material and two base members welded and fixed to the bottom of the pipe frame, the two pipe materials being welded at right angles to the pipe frame at the top of the pipe frame, The two base members are welded at right angles to the pipe frame at the bottom position of the pipe frame, and when the engine generators are stacked and mounted on both side surfaces of the two base members. And forming an engaging portion for engaging and fixing the two pipe members to be welded to the top portion of the pipe frame of the engine-driven generator arranged at the lower position.

Further, as a next feature, elastic members are attached and fixed to both ends of the base member so as to cover each end of the base member.

Reference numeral b denotes a base member which is welded to the bottom of the pipe frame 2 to fix the engine E and the generator G and which constitutes a part of the outer frame body F.

The pipe frame 2 shown in FIGS. 1 and 2 is
When the engine E and the generator G are molded into the interior, the frame of the top portion of the pipe frame 2 is reinforced and the engine-driven generator 1 is stacked and stacked. The pipe members 2a and 2b are welded to the locking positions where they are engaged with base members 3a and 3b, which will be described later.

Further, as shown in more detail in FIGS. 3 to 4, base members 3a and 3b made of channel steel are welded to the bottom portion of the pipe frame 2,
The outer edges of the bottom surfaces of the base members 3a and 3b are formed with engaging portions 3d so as to engage with the outer diameters of the pipe members 2a and 2b welded to the pipe frame 2, and as shown in FIG. The movement of the material 2a in the direction indicated by the symbol Y of the base member 3a is restricted.

Elastic members 5a, 5b, 5c and 5d molded to have a shape to cover the base members 3a and 3b are attached to the respective end portions of the base members 3a and 3b. Fitting portions 5e for mounting the base members 3a and 3b are provided on the upper surfaces of the elastic members 5a, 5b, 5c, and 5d, which facilitates mounting.

FIG. 4B shows the elastic member 5a shown in FIG.
The elastic member 5a is an end portion of the base member 3a for forming the engaging portion 3d for hooking the pipe material 2a to be welded to the pipe frame 2. The outer circumference is covered.

When the elastic member 5a is put on the outer periphery of the end portion of the base member 3a, a cut 5e is provided at the top portion of the elastic member 5a to facilitate the covering. Then, the elastic member 5a, in which the fitting portion 5e is expanded, is attached and fixed to the base member 3a having the outer peripheral surface to which the elastic member 5a is applied and the adhesive coating process. The base member 3a is a channel member, but the portion of the base member 3a which is in contact with the installation surface of the base member is a reinforcing member 3c in order to reinforce the outer frame.

FIG. 4A shows a pipe member 2a and a base member 3a to which elastic members 5a in a stacked state are attached.
However, since the elastic member 5a is attached to the gap between the pipe member 2a and the base member 3a, the base member 3a is attached to the pipe member 2a in the direction indicated by the symbol X. Movement restrictions are imposed. Therefore, the movement of the base member 3a in any direction is restricted by the engaging portion 3d of the base member 3a.

The elastic member 5a described above is
The environment in which an engine-driven generator is used cannot be said to be good, so it is not necessary to limit the material as long as it is heat-resistant, oil-resistant, and hard-curing. Absent.

The situation in which the engine-driven generator 1 having the pipe-shaped frame structure of the engine-driven generator of the present invention is stacked and mounted will be described with reference to FIGS. 4 to 5. The symbol A is
The position of the engine-driven generator 1 located at the bottom is shown. The engine-driven generator 1 is stacked at the second position B, which is the upper position of the engine-driven generator 1.
Is placed.

At this time, the engine-driven power generation at the second-stage arrangement position B is performed on the two pipe members 2a and 2b welded to the top portion of the pipe frame 2 of the engine-driven generator 1 located at the arrangement position A. When the machine 1 is rotated 180 degrees and placed, the engaging portions 3d of the two base members 3a and 3b welded to the bottom portion of the pipe frame 2 have the two pipe members 2
Y shown in (a) of FIG. 4 in order to be engaged with a and 2b.
Restrict movement in any direction.

Further, bottom portions 6a of the elastic members 5a, 5b, 5c and 5d attached to the respective ends of the base members 3a and 3b.
Thus, the two pipe members 2a and 2b are pressed by the own weight of the engine-driven generator 1 itself, and the movement in the Y direction shown in FIG. 4A is restricted. Further, the weight distribution between the engine E and the generator G becomes uniform at the time when the stacking at the second-stage arrangement position B is completed, and stable stacking is realized without an unbalanced load. Position of 3rd stage and 4
After carrying out stacking and placing at the stage arrangement position (not shown), there is no collapse of the load due to an unbalanced load even if it is transported by truck.

Next, the operating condition of the engine-driven generator 1 having the pipe-shaped frame structure of the engine-driven generator of the present invention at the work site will be described. When the conventional engine-driven generator 1 having a pipe frame structure is directly placed on the ground, the contact portion makes a line contact with the pipe diameter of the pipe frame, and therefore the sliding movement is caused by the vibration generated by the operation of the engine. However, there are elastic members 5a, 5b, 5c, 5d protruding from the pipe frame 2 and attached.
Therefore, the vibration due to the operation of the engine is not directly transmitted to the ground. Therefore, each elastic member 5 with respect to the ground
By making the bottom surface portions 6 of the a, 5b, 5c, and 5d in surface contact, vibration of the engine operation is absorbed and the sliding movement of the engine-driven generator 1 during operation is prevented.

[0024]

According to the pipe-shaped frame structure of the engine-driven generator of the present invention described above, the following effects can be obtained. When stacking engine generators with pipe frame structure for stacking for storage or truck transportation, the engaging parts formed on both sides of the base member welded to the pipe frame of the engine generator are arranged in the lower stage. Since it engages with the pipe material of the pipe frame of the engine-driven generator that has been set, the longitudinal movement of the base members of the engine-driven generator that are stacked at the upper position is restricted. In addition, the elastic member attached to each end of the base member regulates the longitudinal movement of the pipe material welded to the pipe frame of the engine-driven generator arranged in the lower stage. Therefore, even when a plurality of engine-driven generators are stacked, it is possible to prevent damage due to a fall and personal injury. Further, since the engine-driven generator at the upper position is rotated 180 degrees with respect to the engine-driven generator at the lower position so that the pipe-shaped frame structure can be placed and stacked, an unbalanced load is not stacked. In addition, stable stacking and placement becomes possible. Further, since the elastic member is attached to each end of the base member, it is possible to prevent the movement of the machine due to the vibration generated by the operation of the engine.
