Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile press-fitting / pulling machine with a crane which moves on an existing pile row.

[0002]

2. Description of the Related Art A pile press-in / pull-out machine for constructing a pile row while moving on the pile row has been used for pile driving work on a river or a coast. In this device, a crane is fixed to the device and used in order to supply piles to the chuck and convey equipment and quality materials. FIG. 7 shows a state of pile row construction by such a pile press-fitting / pulling machine with a crane. The pile press-fitting / pulling machine A with a crane moves along the river B while press-fitting the pile to the river bottom. P1, P2, P3 ... Are piles press-fitted by the pile press-fitting / pulling machine A, and the pile press-fitting / pulling machine A is the piles P1, P3.
The work is advanced while moving on the existing pile row composed of 2, P3 ....

[0003]

By the way, in the above-described pile press-fitting / pulling-out machine A with a crane, the crane C is mounted on the main body so as to be capable of undulating. When there is a low obstacle such as the bridge D in the traveling direction of the pile press-in / pull-out machine A, the crane C collides with the bridge D, and there is an inconvenience that the crane C cannot proceed any further and the work cannot be continued. Especially under the bridge, the device may not be able to pass through at a height of several cm, so it was necessary to lower the device height even slightly. The present invention has been made in consideration of such circumstances, and an object thereof is to provide a pile press-fitting / pulling machine with a crane that can avoid collision when there is an obstacle.

[0004]

The pile press-fitting and extracting machine with a crane according to the present invention moves on an existing pile row by a relative slide between a saddle having a clamp hung at the bottom and a table having a chuck at the front end. At the same time, the pile press-fitting / extracting machine with a crane, wherein the crane is displaceably attached to the table so as to be substantially flush with the upper surface of the table. In this case, the crane can be mounted on the table so that it can be laid down sideways or backward.

[0005]

[Function] When the self-propelled moving on the existing piles, the crane becomes the same height as the table by displacing the crane sideways or backward, as appropriate, so that even if there is an obstacle in front of the existing pile row, There is no obstacle to the progress.

1, 2 and 3 are a plan view, a side view and a rear view, respectively, of a first embodiment of the present invention. A table 3 is provided on the saddle 2, a crane 10 is mounted on the table 3, and a pile press-fitting and extracting machine 1 with a crane is installed.
Is configured. The saddle 2 and the table 3 are movable relative to each other in the pile row direction, and the relative movement enables the vehicle to travel on the pile row. The crane 10 is
It can be attached to one side or both sides of the table 3.

Next, a mechanism for self-propelling will be described. A plurality of clamps 4 hang down on the saddle 2, and each clamp 4 has a structure for clamping and releasing an existing pile by a fluid pressure cylinder. On the other hand, at the tip of the table 3, there is provided a chuck 5 which holds a pile and press-fits it. The chuck 5 is attached via a lifting cylinder 6 so as to be vertically movable. Then, the chuck 5 is lowered while holding the pile, whereby the pile is press-fitted, and the chuck 5
The pile is pulled out by the rise of. Further, the saddle 2 and the table 3 are relatively slidable via a slide base 7.

When the device having such a structure is self-propelled,
First, a moving pile is press-fitted at the tip of the pile row, and a new pile is press-fitted by connecting to the moving pile. During this press-fitting, the press-fitting is temporarily stopped and the clamp 4 is released with the chuck 5 sandwiching the press-fitting pile, and the saddle 2 and the table 3 are lifted and moved forward by one pile. Then, the saddle 2 and the table 3 are then lowered to hold the existing pile by the clamp 4, and then the chuck 5 is lowered to completely press-fit the press-fitted pile. By repeating such operations in sequence, pile 1
It is possible to move forward on the existing row of piles one by one.

The crane 10 is mounted on the table 3 via a bracket 11 attached to the side of the table 3. The crane 10 is provided with a rotary plate 12 and a hoisting cylinder 13 so that the crane 10 can be swung and hoisted with respect to the table 3 and can be expanded and contracted, so that piles and other materials are transferred. The mounting of the crane 10 on the bracket 11 is performed by rotatably attaching a horizontal shaft 15 extending in the front-rear direction to the bracket 11 and inserting the horizontal shaft 15 so as to be orthogonal to the support shaft 14 of the crane 10. It is being appreciated. The horizontal shaft 15 and the support shaft 14 are integrally assembled by engaging means such as a key and a key groove, and the horizontal shaft 1
5 is connected to a rotary drive source (not shown) such as a hydraulic motor. Therefore, when the horizontal shaft 15 rotates, the crane 1
As for 0, the whole is displaced from the solid line state to the chain line state, and at the same time, the chain line state is returned to the solid line state. Here, the solid line state is the work posture in which the crane 10 stands up on the table 3, while the chain line state is the sideways posture in which the crane 10 is retracted from the table. In this overturned state, the crane 10 is substantially flush with the upper surface of the table and projects laterally of the table 3. As a result, the height of the table 3 as a whole is reduced, so that even if there is an obstacle such as a bridge, the interference with the obstacle does not occur, and the movement passing under the obstacle can be continued.

4 to 6 show a second embodiment of the present invention, in which the same elements as in the first embodiment are designated by the same reference numerals and correspond to each other. In this embodiment, the crane 10 is arranged so as to be located at a substantially central portion on the table 3. Further, a horizontal shaft 15 for mounting the crane 10 is provided along the left-right direction of the table 3, and the support shaft 14 of the crane 10 is orthogonally assembled to the horizontal shaft 15. In this embodiment, if there is an obstacle at the top, first rotate the crane 10 horizontally by 90 degrees,
The pile press-fitting / pulling machine 1 is set in an orthogonal state. When the horizontal shaft 15 is rotated in this state, the crane 10 is rotated from the solid line state in the arrow direction shown in FIG. The crane 10 in the chain line state is in a state of lying sideways behind the table 3 in a state of being substantially flush with the upper surface of the table 3. In such a state, the protrusions of the table 3 are eliminated, so that it is possible to travel under the obstacle at a site requiring a space of several cm.

[0011]

Since the present invention has a structure in which the crane is displaced so as to be substantially flush with the upper surface of the table, even if there is an obstacle, traveling on the pile row can be continued without interference.
