Next, the traveling machine 2 for transporting the work machine has a traveling power unit 22 mounted on a mounting table 21 provided in the traveling device 20.

In the embodiment, a crawler traveling device is used as the traveling device 20.
This crawler traveling device has crawlers (crawler belts) 20a arranged in parallel on the left and right sides, and this crawler 20a is wound between a drive wheel 20c provided at one end of a track frame 20b and a driven wheel 20d provided at the other end. It has been turned.

The travel power unit 22 is for driving the travel device 20 by hydraulic drive or electric power drive, and is provided with a cable connection 24 for receiving external power.
Therefore, the cable connection 14 for power transmission for the traveling machine provided in the generator 12 of the portable work machine 1 and the cable connection 24 for receiving external power provided in the work machine transfer traveling machine 2 are connected to the power cable. If connected by 30, electric power can be supplied to the traveling power unit 22 from the generator 12 of the portable work machine 1.

Thereby, if the traveling machine 2 for transporting the work machine is traveled in a state where the portable work machine 1 is placed, the portable work machine 1 can be moved at the off-road site.
In addition, the work machine transporting traveling machine 2 can be traveled in a state separated from the portable work machine 1, and in the state separated from the portable work machine 1, the travel range of the work machine transporting traveling machine 2 is The length of the power cable 30 is limited.
In addition to the generator 12 of the portable work machine 1, a separate generator or a commercial power supply can be used as a power source for running the work machine transporting runner 2.

As described above, the portable work machine 1 is detachably attached to the work machine transporting traveling machine 2, and the attaching / detaching structure is attached to the mounting table 21 of the work machine transporting traveling machine 2. On the other hand, the traveling machine attaching / detaching part 13 is provided on the machine base 10 of the portable work machine 1, and the working machine attaching / detaching part 13 and the traveling machine attaching / detaching part 23 are attached and detached.

In the embodiment, a concave portion as a traveling machine attaching / detaching portion 13 is formed on the lower surface of the machine base 10 of the portable work machine 1, and the mounting table 21 is provided so as to be detachably fitted into the traveling machine attaching / detaching portion 13 (concave portion). The mounting table 21 itself is formed as a work machine attaching / detaching part 23 so as to be detachably fitted into the traveling machine attaching / detaching part 13 (recessed part).
The attachment / detachment structure is not limited to the above-described embodiment, and any structure can be used as long as the machine base 10 of the portable work machine 1 can be securely placed and fixed on the stage 21 of the work machine transfer traveling machine 2. good.

An example of usage of the portable work device 3 of the present embodiment will be described. Usually, the traveling machine 2 for transporting the work machine and the portable work machine 1 are separated from each other, and the portable work machine 1 alone is set at a predetermined off-road site. The rock crushing work is performed with the jaw crusher as the work machine 11 in the state of being installed at the position.
The separated traveling machine 2 for transporting the work machine may be moved and stored independently at an appropriate place on the off-road site, or it may be loaded on a trailer and transported to a predetermined place and stored there. You can leave it.

Also, a single work machine transporting traveling machine 2 is prepared for a plurality of portable work machines 1, and the work machine transporting traveling machine 2 is installed in a plurality of transportable machines having different installation locations and types of work machines 11. It can be used as a common moving means for the work machine 1.
In this case, the traveling machine attaching / detaching portions 13 to be formed on the plurality of portable work machines 1 are formed in the same structure, and all of them can be attached to and detached from the working machine attaching / detaching part 23 of the working machine transporting traveling machine 2. It is necessary to form.

Then, when it becomes necessary to move the portable work machine 1 within the off-road site, the work machine transfer traveling machine 2 is transported from the storage location to the off-road site, where there is a gap between the cable connection portions 14 and 24. The power cable 30 is connected to enable the work machine transporting traveling machine 2 to travel.
Next, after the machine base 10 of the portable work machine 1 is raised by the outrigger 15, the work machine transfer traveling machine 2 is moved and traveled below the machine base 10 of the portable work machine 1.

Next, as shown in FIG. 2, the machine base 10 of the portable work machine 1 is lowered by the outrigger 15 so that both the attachment / detachment parts 13 and 23 are connected to each other so that the portable work machine 2 can be carried on the traveling machine 2. The work machine 1 is mounted, and the work machine transfer travel machine 2 is moved in this state to move the portable work machine 1 to a predetermined position. At this time, the outrigger 15 is kept in the retracted state.

Then, after the portable work machine 1 is moved to a predetermined position by the work machine transfer traveling machine 2, the base 10 of the portable work machine 1 is raised by the outrigger 15 so as to release both the attaching / detaching portions 13 and 23. Thereafter, the work machine transporting traveling machine 2 is taken out from below the machine base 10 of the portable work machine 1 to separate the work machine transporting traveling machine 2 from the portable work machine 1.
In addition, in order to make attachment / detachment work easy, the mounting table 21 of the traveling machine 2 for transporting the work machine can be formed to be movable up and down by appropriate lifting means (not shown).

Then, the portable work machine 1 is installed reliably and stably by the outrigger 15, and the rock crushing work is again performed by the jaw crusher as the work machine 11.
The separated work machine transporting traveling machine 2 moves to a predetermined storage location, or is transported to a predetermined storage location by a trailer or the like, and waits until the next dispatch.

In the present invention, the portable work machine 1 and the work machine transfer traveling machine 2 are used separately in a separated state, and can be manufactured and sold separately. Therefore, the portable work machine (Claims 1 and 2) and the traveling machine for transporting the work machine (Claim 3) are independent inventions.
Further, when the portable work machine 1 is moved by the work machine transfer traveling machine 2 at the off-road site, it is necessary to use the portable work machine 1 and the work machine transfer running machine 2 in combination. The portable work device in the state (Claim 4) is also an independent invention.
