DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables a plurality of working machines to be stacked one upon another when storing an engine-driven generator housed in a pipe frame structure, and at the time of operation, vibrations generated from the engine. The present invention relates to a pipe-shaped frame structure of an engine-driven generator for preventing the sliding movement of the machine main body accompanying the above.

[0002]

2. Description of the Related Art For example, a generator using an engine as a driving source is required to be used at a construction site or the like. Have been. However, in recent years, due to space problems in storage warehouses, etc., efficient use of these spaces and improvement and improvement of equipment have been demanded.For example, medium- and large-sized engine-driven generators suffer from strength problems. A countermeasure has been made by adopting a box-shaped structure that can cope with the problem by reinforcing the frame or the like so that stacking and mounting can be performed.

On the other hand, taking a small engine-driven generator as an example, in many cases, the frame of the generator usually employs a pipe frame structure in order to reduce the weight. In order to achieve this, it is required to have a structure that can be stacked as much as possible.

[0004]

The structure of the outer frame of a small engine driven generator employing a pipe frame structure is disclosed in Japanese Utility Model Application No. Sho 55-120946 (Japanese Utility Model Application Laid-Open No. Sho 57-145).
255), the structure of the outer frame disclosed in Japanese Utility Model Application No. 55-120946 has an upper pipe frame stacked on the outer edge portion of the pipe frame. When placed on the pipe frame, the end of the connecting member provided at the bottom of the upper pipe frame protrudes the end to be engaged with the pipe diameter of the lower pipe frame to form an arc surface By doing so, a solution is achieved.

[0005] In the outer frame structure of the pipe frame having such a configuration, when the lateral rubbing (lateral direction) occurs, the pipe frame can regulate the lateral rubbing. In the case of rubbing in the direction, there is no means to regulate the movement, so there is little problem in stacking management in storage warehouses unless there is extreme vibration, When stacking and transporting by truck or the like, accidents such as collapse of cargo may occur.

On the other hand, when a multi-pole magnet high-frequency generator is used for the generator of the engine-driven generator in terms of size and weight reduction, the generator becomes extremely small with respect to the engine.
The weight balance of the entire machine is shifted toward the engine. Therefore, when such generators with poor weight balance are stacked on top of each other, as described above, a load collapse accident occurs during truck transport, and when the generators are operated at a construction site, the There is also a problem that it gradually moves due to the vibration of.

Therefore, the present invention has been made to solve such a drawback, and an engine generator having a pipe frame structure is stacked and stored in a storage warehouse or stacked and moved by a truck or the like. In this case, even if the center of gravity of the stacked engine generators is in an unbalanced state, the engine drive generator located at the lower stage in the engagement portions formed on both side surfaces of each base member welded to the pipe frame. The pipe material welded to the top of the pipe frame of the machine is engaged, restricting the movement of the engine-driven generator, and further, when a plurality of stages are stacked, the engine-driven generator is rotated by 180 degrees. Rotate to enable alternate placement,
Still another object of the present invention is to provide a pipe-shaped frame structure of an engine-driven working machine, in which an elastic member attached to each end of a base member can prevent movement of a machine main body due to vibration by an engine. Is what you do.

The pipe frame 2 shown in FIGS.
It is molded into a shape that houses the engine E and the generator G. The frame at the top part of the pipe frame 2 is strengthened, and the engine-driven generator 1 is mounted in a stacked manner. The pipe members 2a and 2b are welded to the engaging positions where they are engaged with base members 3a and 3b described later.

Further, base members 3a and 3b made of channel steel are welded to the bottom portion of the pipe frame 2 as shown in FIGS. 3 and 4 in more detail.
The outer edge of the bottom of the base members 3a, 3b is formed with an engaging portion 3d so as to engage with the outer diameter of the pipe material 2a, 2b welded to the pipe frame 2, and as shown in FIG. The movement of the material 2a in the direction indicated by the reference character Y of the base member 3a is regulated.

An elastic member 5a, 5b, 5c, 5d molded in a shape to cover the base member 3a, 3b is attached to each end of the base member 3a, 3b. Fitting portions 5e for mounting the base members 3a, 3b are provided on the upper surface portions of the elastic members 5a, 5b, 5c, 5d to facilitate the mounting.

Next, the operation of the engine-driven generator 1 with the pipe-shaped frame structure of the engine-driven generator of the present invention at the work site will be described. When the engine driven generator 1 having the conventional pipe frame structure is placed directly on the ground, the contact portion thereof comes into line contact with the pipe diameter of the pipe frame, so that the sliding portion is slid by the vibration generated by the operation of the engine. There are elastic members 5a, 5b, 5c, 5d which are protruded from the pipe frame 2 and adhered.
Therefore, the vibration caused by the operation of the engine is not directly transmitted to the ground. Therefore, each elastic member 5
Since the bottom surface portions 6a, 5b, 5c and 5d are in surface contact, the 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 structure of the pipe-shaped frame of the engine driven generator of the present invention described above, the following effects can be obtained. When stacking an engine generator with a pipe frame structure 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 row In order to engage with the pipe material of the pipe frame of the engine driven generator, the base member of the engine driven generator stacked in the upper position is restricted from moving in the longitudinal direction. Further, each end portion attached to the elastic member of the base member, that Wins the longitudinal movement of the pipe is welded to the pipe frame of the engine generator disposed in the lower member regulations. Therefore, even when a plurality of engine-driven generators are stacked, it is possible to prevent damage due to overturning and personal injury. Furthermore, since the engine-driven generator at the upper position is rotated 180 degrees with respect to the engine-driven generator at the lower position to form a pipe-shaped frame structure that allows for step-by-step loading, uneven stacking is prevented. In addition, stable stacking can be performed. In addition, 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.
