DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile press-in / pull-out machine for loading large equipment and loading or removing pile rows, and more particularly to minimizing the width and height of the body. The present invention relates to a pile press-in / pull-out machine for loading a large-sized device capable of mounting a hose reel or the like while keeping it to a minimum.

[0002]

2. Description of the Related Art A pile is driven by an auger method by mounting a hose reel integrally with a pile press-in / draw-out machine in order to adjust a hydraulic supply hose for driving an auger in and out in accordance with the vertical movement of the auger. I do. In this case, since the hose reel needs to receive the hydraulic hose from the hydraulic supply source behind the mast of the pile press-in / pull-out machine, it must be mounted on the mast. However, in the above case, installing the hose reel on the top of the mast of the pile press-in / pull-out machine increases the height of the machine by that much. Since it is not possible, the pile press-in / pull-out machine and the hose reel were separated and conveyed to the construction site, and then the hose reel had to be attached to the body of the pile press-in / pull-out machine at the piling site where working conditions were poor. In order to avoid this problem, as shown in FIG. 3, a so-called low-head type pile press-in / pull-out machine 101 called a clear piler (trade name) having a reduced total body height is used for pile driving under a bridge or the like. By mounting the hose reel thereon, a pile press-in / draw-out machine with a hose reel having a small overall height can be configured.

[0003]

However, the clear pillar type pile press-in / pull-out machine 101 has to be configured to have a large overall width W in order to suppress the overall height of the body. That is, since the mast cannot be set up, the press-fitting chuck 10
In order to secure the up-and-down movement stroke of 2, a rail 103 is provided on the press-fitting chuck 102 on the movable side, and a guide 104 for receiving the rail 103 is provided on the turning frame 106. In this case, the rail 103 and the guide portion 104
Since it is difficult to secure sufficient strength due to dimensional restrictions imposed by height restrictions, vertical drive cylinders 105, 105 are provided on both sides of the press-fitting chuck in order to suppress the moment acting on these rails 103 and guides 104. As shown in FIG. 4, the machine body width dimension W is determined by the diameter of the press-fit chuck 102 and the cylinder 105.
The size of the diameter must be added to increase the size. Therefore, the construction in a narrow place is greatly restricted.

[0004] It is an object of the present invention to provide a press-fitting pile capable of minimizing the width and height of the body and ensuring workability even when equipment having a large height such as a hose reel is mounted. An object of the present invention is to provide a drawing machine.

[0005]

In order to solve the above-mentioned problems, in order to solve the above-mentioned problems, a revolving frame supported horizontally by a revolving shaft raised on a reaction force base, and a guide provided at a front portion of the revolving frame. A mast supporting the guide rail is pivoted in a pile press-in / pull-out machine equipped with a press-fitting chuck provided to be able to move up and down via a rail and a hydraulic cylinder for driving the same up and down, and further loading a large device such as a hose reel. A hydraulic cylinder is arranged upright on the frame, a hydraulic cylinder is arranged behind the press-fit chuck at the tip of the revolving frame, and a hydraulic control unit for driving and controlling the hydraulic cylinder and the like is provided behind the revolving shaft. Section is configured to receive a hydraulic hose from a hydraulic supply source, and a space for loading equipment is formed on the back of the mast above these pivots and the hydraulic control section. To.

[0006] In this pile press-in and pull-out machine, a mast supporting the guide rail is formed upright on a revolving frame.
It is possible to secure sufficient strength to oppose the rotational moment based on the distance between the hydraulic cylinder and the press-fit chuck, and to reduce the overall width by arranging the hydraulic cylinder behind the press-fit chuck at the tip of the turning frame. Since the hydraulic control unit can be minimized and the hydraulic control unit is provided behind the turning axis, the large space behind the mast above the hydraulic control unit and the hydraulic pressure from the hydraulic supply source behind the hydraulic control unit Hose connection space is secured.

By arranging a hose reel for a hydraulic supply hose to an attachment, such as for driving an auger, on the back of the mast, a pile press-in / draw-out machine having a hose reel can be formed while suppressing the overall height of the machine body. Therefore, the pile press-in / draw-out machine provided with the hose reel can be transported to the construction site as it is. Therefore, it is possible to carry out the press-fitting work immediately after loading the pile press-in / draw-out machine. Further, since the entire width of the fuselage is minimized, construction can be performed without difficulty even in a narrow place.
