Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a machine f that stubbornly and freely inserts sails when
” Regarding Shin. vE, - The straight-loading type pile driving castle should be fixed on the existing pile A as shown in Figure 1. Elevating device 4 that makes the ascending body 5 rise; controlled by the ascending body 5 1
It was a long time to remember how to use the pegs for the prayer, piling, -〇&timesushi piles, and 9 temples as the bag section, but in this type of pile driving, there are many types of pilings, such as the following: The pressure cylinder) 4 is housed in the guide frame 5 and is raised, r4 M
vii 4's milling pile 11 was missed, and from the force, the center of the valley of Ichishi equipment 4 and anti-layering device 9, - was not aligned. Well, this kind of reduction in pile driving...
From the pile driving mark VC% Ikemori to the center 1 of the pile grip table 19
Due to the overstretching reaction force F generated on the surface, the distance between the center, the center of the iron and the center, the center point of 4 Tables 1 & 4, - and the center point of L7- is × τ/
Since the reaction force moment (moment) M acting on the J-shaped uphill battle θ is applied, a strong load will be applied between the sliding part of the elevating body 5 and the side of the guide frame 5 (however, the mounting method of the elevating device −
For example, the position of the fulcrum varies depending on the vertical positional relationship between the loft and the cylinder, but the reaction force moment M always acts. ), therefore, the sliding surfaces suffered severe wear, and the guide frame 5 was required to have strong rigidity, making the pile driver as a whole high in its center of gravity and unstable. Moreover, when viewed from the pile driving machine as a whole, the reaction force is such that the existing pile group held by the reaction pile gripping device fi1-2 at the bottom of the foundation 1 is used as a fulcrum to tilt the pile in the direction of the pile driving depression tm. Since it acts as a force moment M', even if the pile driver is placed so that the pile gripping device 9t is initially vertical and then starts driving the pile, the reaction force from the ground increases as the pile is driven. There is a natural tendency for the pile B to tilt backwards, and for this reason, as shown in Figure 2, a pile driving machine has been developed that allows the guide frame to be tilted freely and drives the pile after tilting it forward in advance. However, since the fulcrum 12 that supports the guide frame 3 in a tiltable manner was provided separately from the other fulcrums, the number of m was increased to 44, which was more than necessary, and the problem caused by the above-mentioned "center mismatch" was also eliminated. Firstly, the present invention has many drawbacks such as requiring the tilting device 2 to be strong.The present invention has many drawbacks such as the need for the tilting device 2 to be strong. It is an object of the present invention to provide a pile driving machine which is free from electric charge, allows the pile gripping device 9 to easily and freely tilt, has a low center of gravity, and is equipped with a lifting device with more strength. That is, in the pile driver of the present invention, as shown in FIG. 4, the guide frame 3 is tiltable with respect to the base 1,
When viewed from direction A, the pivot center of the pile milling device 9 about the vertical axis is aligned above the guide frame 30 - the dynamic fulcrum and the center of the lifting motion of the lifting device 4, and the lifting body Outside of 5-
It is characterized by the placement of 4-4 on the surface. Hereinafter, the configuration of the pile driver of the present invention will be explained using examples thereof. As shown in FIGS. 4 to 6, a pile driving machine as an actual row of piles according to the present invention has a base 1 to be set on the existing pile A group (details will be described later); The bottle 6 is rotatably fitted into a part of the support arm 8 that is integral with the bottle 61.

; and so on as its main parts, and in more detail, the structure around the bottle 6 is as shown in Fig. 4.6.
A bracket 7, which has a cross-sectional shape with a stopper 11 at its top and is integral with the guide frame 5, is provided so as to protrude forward from the lower part of the guide frame 3. Near the front end of the bracket 7, a pin 6 to which a pin 6 is pivoted with -6 horizontally has 4 lowering a (hydraulic cylinder in the embodiment) 4 protruding from 9 lots 1o. are fixed as one unit. On the top 4 of the base 1 (strictly speaking, in the embodiment, the left and right sliding table 1-4) is provided with a support arm 8 integrally formed with the base 1, the upper part of which is straight at an appropriate angle. It is being The support arm 8

Reaction pile gripping device 1- that moves once and clamps the existing pile At#
2. On the upper part of the pedestal 1-1, there is a front and back sliding table 1-3 which is slidably mounted as described above and a support arm at the upper part.
- Formed as one piece, front and back sliding table 1-3
It consists of a left and right slide table 1-4 mounted so as to be able to slide left and right on the top thereof. In an embodiment, the drive for each motion part uses an independent hydraulic cylinder. The operation and effect of the pile driver of the present invention constructed as described above will be explained.

As shown in Figure 4, the existing pile A# is used as a reaction pile for pile driving.
After fixing the base 1 with the reaction pile gripping device 1-2, the pile gripping device 9 grips the work pile Bt-, and the tilting device 2 is operated to move the guide frame 3 (therefore, the pile gripping device 9) f The pile is driven by tilting the knee to the desired angle.
In the pile driver of the present invention, the center of the bin 6 and the lifting device 4 are
Center of - and pile gripping device f? Since the centers of and lines coincide with each other when viewed from all sides, the bottle 6 is pulled up by the reaction force F from the ground, but between the sliding part of the elevating body 5 and the side of the guide frame 3. Because the reaction force moment M that would destroy a shallow load does not act on the conventional pile driver (5g1~3
(see figure), there is no longer any need for a guide frame with strong rigidity, and the bin 6 (+- Since the rotatably fitted part becomes the main part to support the reaction force Fτ, the center of gravity of the pile driver becomes very low and stable as a safe, and the pin 6 supports 5ILJliτ of the guide frame 5. This eliminates the need for the inclined extension 12 to be as strong as it used to be, and furthermore, if an abnormal reaction force were to be generated during pile driving, the guide frame 3 would be likely to be blown further away than necessary. However, since the support can be stopped by the stopper 11, the tilting device L2 can be easily miniaturized. Although the plan is to increase the number of structures and make the piles larger, since the Noboru 4 device 4 is attached to one side of the Noboru 4 kotsu 5, it is not possible to use the more powerful 44 device and other related accessories for compatibility. There is also the advantage that the pile driver of the present invention can be installed without any force control (if the lifting device is built into the pile gripping device 9, the advantage force will be eliminated). ``Self-propelled'' is a machine that grips the work pile B, raises the main body, and places the main body on the adjacent pile, as shown in the example of the operation shown in Figure 7, without lifting and moving other machines such as (Movement on the existing pile using only the pile driver 0 This includes both forward movement and backward movement with the pile driver of the present invention) 0 or more,
Although the description has been mainly given to the case of driving piles, it is clear from the drawings and the above description that the pile driver of the present invention can also be used for pulling out piles, so the description will be omitted.
