DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile setting device in a low space pile driving work for setting a pile in a pile driving device.

[0002]

2. Description of the Related Art Conventionally, as a method of setting a pile in a pile driving device in low space pile driving work, (1) a method using a small crane.

(2) A method using a wire by a pile driving device itself.

(3) A method using human power.

[0005]

[0006]

In the method (1) using a small crane, there is a dead space such as a hanging hook and a sling wire, so that the pile length per rod cannot be increased. In order to secure the predetermined embedding, the number of joint piles increases, and both the work efficiency and the capacity decrease.

In the method (2) using the fishing wire of the pile driving device itself and the method (3) using the human power,
The weight per pile is limited, and both the work efficiency and the capacity are reduced as in the method (1), and there is room for improvement and necessity compared to the recent mechanization and robotization of other work.

On the other hand, the present applicant has filed a Japanese Patent Application No. 5-1788.
No. 84 proposes a pile installation method and a pile installation method in a low space pile driving work that can cover all the disadvantages of the conventional method and can safely and efficiently install the maximum pile length in a limited upper space. ing.

Although the above proposal itself is effective, however, there are difficulties in the operation of moving the pile to a predetermined position after laterally gripping the pile and the operation of gripping the erect pile by its own weight, resulting in poor workability. .

[0010] The present invention covers all the disadvantages of the conventional method, and is a pile construction in low space pile driving work with good workability which enables safe and efficient construction of a maximum pile length in a limited upper space. It is intended to provide a storage device.

[0011]

According to the present invention, a low space piling machine is provided on a base machine via a positioning means, and the low space piling machine is provided with a horizontal rotating shaft and the rotating shaft. A pair of arms, one end of which is fixed to the rotating shaft, a holding device provided at the other end of the pair of arms for laterally holding a pile at a predetermined position and holding the same, and the holding device In a pile construction device in low space construction provided with a driving means, a main body of the holding device is formed in a rectangular frame, and a feed roller and a feed for driving the feed roller are provided on one arm side of the frame. A motor is provided, and on the other arm side, a chuck roller capable of moving back and forth with respect to the feed roller and a means for moving the chuck roller back and forth are provided.

[0012]

According to the pile driving device used in the low space pile driving device constructed as described above, after the position of the low space pile driving device is determined by the positioning means, the pile is laterally gripped and laterally moved to a predetermined position. After standing upright, the chuck is vertically moved and gripped by the chuck, so that a conventional crane or the like is unnecessary, and a long pile can be installed with good workability even in a low and narrow space.
