Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a work handle suitable for use in a hand-held compaction machine such as a compaction machine.

[Prior art]

Conventionally, compaction machines such as compaction machines called tamping rammers or vibrorammers have been widely used as devices for compacting uneven ground surfaces into a flat surface.

By the way, as shown in FIG. 3, the work handle A in this type of pressure machine is operated by a worker E who stands on the same surface as the ground surface D where the pressure plate C provided at the lower end of the machine body B is located. It is placed at a height convenient for operation.

[Problem that the invention attempts to solve]

By the way, when laying pipe bodies such as gas pipes, communication cable pipes, water pipes, or power cable pipes in excavated trenches, backfilling the pipe bodies laid in the trench bottom with earth and sand is carried out every predetermined thickness. In order to gradually flatten the excavated trenches, a compaction machine is introduced into the excavated trench to carry out compaction work. Normally, the width of this type of excavation trench is set to a size that allows the worker to enter the trench with the pressure machine and operate the machine, but the pressure machine constantly applies vibrations to the bottom of the trench. Furthermore, as soil transport vehicles approach the ditch, the earth pressure increases, so there is a high risk that the ditch walls will collapse and workers will be buried in the dirt.

Therefore, in recent years, when performing pressure work in excavated trenches, in order to ensure the safety of the work, a method has been adopted in which only the pressure machine is placed inside the trench and the worker operates the machine from outside the trench. It has been adopted.

However, as mentioned above, the pressure machines currently on the market have operating handles located at a height that makes it easy for workers working on the same surface as the pressure machine, so it is difficult to use the pressure machine placed in an excavation trench. There is a problem in that it cannot be operated freely from outside the excavation trench where the scaffolding heights are different.

Also, recently, the safety aspect as mentioned above,
For the purpose of efficiently excavating and backfilling an excavated trench, there are cases where the width of the trench is set to a size that allows only a compaction machine to be placed. Since the pressure machine inside the trench must be operated from outside the trench, there is a problem in that the machine is very difficult to operate.

[Means for solving problems]

Therefore, in order to solve the above-mentioned problems, this invention aims to connect the work handle of a compaction machine such as a compaction machine to a support frame that stands upright on the top of the compaction machine body, and to this support frame through an operating rod. By comprising a handle member that is movably pivoted, and an adjustment tool that adjusts the position of the handle member via a holding member that is attached to a part of the support frame and pivoted to the operating rod, This allows compaction work to be easily and safely performed from positions with different scaffolding heights, such as outside the excavation trench.

[Effect]

With the work handle according to this invention, compaction work is performed by fixing and holding the height of the handle member pivotally connected to the compaction machine body at a desired position using an adjustment tool.

〔Example〕

Next, as a preferred embodiment of the compaction machine work handle according to the present invention, a compaction machine work handle will be described in detail below.

1 and 2, the work handle 10 according to the present invention has a vibration isolating rubber 16,
A gate-shaped support frame 18 is erected via 16,
A pair of operating rods 22, 22 is rotatably attached to the top end of the support frame 18 via a pivot 20, and a handle member 24 is fixed to the ends of these operating rods 22, 22, and is further supported. frame 18
An adjustment tool 26 for adjusting the position of the handle member 24 is disposed in a part of the handle member 24.

The adjustment tool 26 includes a guide member 28 disposed in the longitudinal direction approximately at the center of the support frame 18.
A cylindrical positioning member 30 is slidably attached to the guide member 8 , and a stopper 32 is provided on one side of the positioning member 30 to fix and hold the positioning member 30 at a predetermined position on the guide member 28 . It is composed of Further, on the other side of the positioning member 30, the other end of a holding member 36, which has one end pivotally connected to a horizontal member 34 connecting the operating rods 22, 22, is pivotally attached.

With this configuration, when the positioning member 30 is slid along the guide member 28, the handle member 24 fixed to the operating rod 22 changes its position via the holding member 36 to the first position with the pivot 20 as a fulcrum. It will be appreciated that adjustments can be made between the dotted line and the solid line as appropriate in the figures.

Next, the case of using the pressure machine having the working handle according to the present invention constructed as above will be explained.

That is, when compacting an uneven ground surface, the positioning member 30 is fixed at the position shown by the dotted line in FIG. 1 using the stopper 32, and the work is performed.
In addition, when compacting earth and sand that has been backfilled onto a gas pipe laid in an excavated trench, the stopper 3
The fixing state of the positioning member 30 is released, and the positioning member 30 is slid along the guide member 28 to set the handle member 24 at the optimum position,
This is done by fixing the positioning member 30 with a stopper 32.

[Effect of idea]

As mentioned above, according to the work handle of the present invention, the handle member can be set at a desired position by adjusting the positioning member, so compaction work can be carried out at positions with different scaffolding heights, such as outside an excavation trench. It not only can be carried out easily and safely from the ground, but also has the advantage of being usable on the ground, and its practical effects are extremely large.

Although the work handle of a compaction machine has been described above as a preferred embodiment of the work handle for a compaction machine according to the present invention, the present invention is not limited to this embodiment. It can also be suitably used as a work handle for a compactor, etc. that flattens the material while compressing it, and it can also be used within the scope of the spirit of the invention, such as by constructing the support frame or operating rod from a single member to simplify the structure. Of course, various modifications can be made.
