[0006]

However, when the pile press-fitting / pulling machine using the attachment is collected, the attachment is heavy and the mounting thereof is troublesome and time-consuming.
Further, when collecting, the piles are moved one by one while being clamped and released one by one, so that the operation is complicated, the speed is slow, and it takes time. Furthermore, since the pile press-in / pull-out machine is raised and lowered as a whole, the operation is unstable and there is a problem in safety. The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a transporting device having a function of traveling on an existing pile and capable of easily and quickly collecting the pile press-fitting / pulling-out machine. To do.

[0007]

In order to achieve the above-mentioned object, a carrying device of the present invention has a base on which a pile press-in / pull-out machine is mounted and at least one of which is arranged in front of and behind the base and is rotationally driven. It is characterized in that it is provided with wheels that roll against each other and guide rollers that project from both sides of the base and roll while rolling the existing piles from both sides.

[0008]

In the above structure, the wheels are driven to rotate while the pile press-in / pull-out machine is mounted on the base, so that the wheels travel on the existing piles. Collection is done. The guide rollers roll on both sides of the existing pile to ensure stability when the pile press-in / pull-out machine is installed and when traveling on the existing pile.

[0009]

1 to 6 show an embodiment of the present invention.
As shown in FIG. 1, the carrying device 10 includes a base 11 and a guide roller 12 arranged below the base 11. Base 11
As shown in FIGS. 3 to 6, the extension extends in the pile row direction of the existing piles P, and wheels 13 and 14 are provided at both ends in the extension direction (front-rear direction). A support block 15 is erected in the longitudinal direction at the center of the upper surface of the base 11. The support block 15 is clamped by the clamp 6 of the pile press-fitting / extracting machine 1 as described later, so that the pile press-fitting / extracting machine 1
Is equipped with.

Wheels 13, 14 provided in front of and behind the base 1
Rotates while contacting with the upper surface of the existing pile P, that is, so as to make rolling contact, whereby the entire carrying device 10 travels on the existing pile P. One of the wheels 13 and 14 is connected to a drive device (not shown) to be rotationally driven, and the other is driven to rotate. In the illustrated example, the wheel 14 is the driving wheel and the wheel 13 is the driven wheel, but the reverse is also possible, and both may be the driving wheels.

The guide roller 12 is attached to a roller frame 16 that hangs below the base 11 (see FIG. 1).
The roller frames 16 are arranged so as to be located on both sides of the existing pile P, and the guide rollers 1 are provided at the upper and lower positions of each roller frame 16.
2 is attached. Therefore, the guide roller 12 rolls from both sides of the existing pile P. FIG. 2 shows a mounting structure of such guide rollers 12, and a plurality of guide rollers 12 are arranged in each roller frame 16 in the longitudinal direction thereof. By arranging the plurality of guide rollers 12 in this way, even if the pile has a bent shape like a steel sheet pile, one of the guide rollers 12 rolls on the pile from both sides.
The base 11 can be stably maintained on the existing pile P.

The guide roller 12 can be adjusted in its facing position according to the width of the existing pile P. In FIG. 1, 17 is a fluid pressure cylinder for performing this adjustment,
The base end 17a is fixed to the lower portion of the base 11, while the piston lot 17b is connected to one roller frame 16 (the right roller frame 16 in the illustrated example). Therefore, the operation of the fluid pressure cylinder 17 causes the guide rollers 12 on both sides of the existing pile P to move toward and away from each other, whereby the distance between the guide rollers can be adjusted according to the size of the existing pile P.

3 to 6 show the recovery operation of the pile press-fitting / pulling machine 1 having the above-mentioned structure. As shown in FIG. 3, the pile press-fitting / pulling-out machine 1 has completed the press-fitting of the final pile Pn and is stopped in this state. The transporting device 10 rotates the wheels 13 and 14 while sandwiching the existing pile P from both sides with the guide rollers 12 to move on the existing pile P to approach the pile press-fitting / pulling-out pattern 1. During this approach, the pile press-in / pull-out machine 1 has the chuck 4 with the final pile Pn.
The main cylinder 9 is operated in a state where it is pinched, and thereby the whole is lifted above the existing pile P. In this state, the carrier device 10 moves below the pile press-fitting / pulling machine 1 (FIG. 4).

When the carrying device 10 reaches below the pile press-fitting / pulling-out machine 1, the slide base 5 slides so that the clamp 6 is located on the supporting block 15, and the clamp 6 holds the supporting block 15. (Fig. 5). After this sandwiching, the final pile Pn sandwiched by the chuck 4 is cut so as to have the same height as the other existing piles P. In FIG. 5, reference numeral 20 is this cutting line. Since the pile press-fitting / extracting machine 1 is separated from the final pile Pn by this cutting, the wheels 13 and 14 rotate in reverse and the carrying device 10 moves backward, so that the pile press-fitting / extracting device 1 moves from the press-fitting site together with the carrying device 10. It is taken out and collected (Fig. 6).

In such a carrying device 10, the pile press-fitting / pulling machine 1 can be quickly collected because it travels on the existing piles P, and the pile press-fitting / pulling machine 1 itself does not need to be moved, so that the collecting work is simple. Becomes Further, since the guide roller 12 is rollingly contacted with the conventional pile from both sides, the stability is good and the safety can be secured. Although the pile press-fitting / pulling machine recovery work is described in the above embodiment, the pile press-fitting / pulling machine can be sent out in the same manner.

[0016]

As described above, according to the present invention, since the pile press-fitting / pulling machine is mounted on the pile so as to travel stably on the pile, the pile press-fitting / pulling machine can be collected and sent out easily and quickly. , Work efficiency is improved.
