Meanwhile, the vertical construction method of piles using a pile driver according to the present invention configured as described above is a method for vertically constructing piles 200 using a pile driver configured as described above.

The vertical construction method of piles using a pile driver (100) includes a driver housing (12) coupled to a coupling bracket (11) coupled to the excavator's boom (110) and bucket cylinder (111) and a hinge axis, and the driver housing (12).

When the pile driver 10 is coupled to the excavator 100 as described above, the actuator 55 of the side grip portion 50 of the pile driver 10 is manipulated to grip the pile 200 for construction. The file grasping step (320) is performed.

In the file gripping step 320, the file 200 is gripped by using the actuator 55 to spread the first and second side grip members 51 and 52 as well as the tilting unit 70 and the swing unit 20. ) is used to hold the file 200 by adjusting the posture of the side grip portion 50 to a state capable of holding the file 200. At this time, there is no need to grip the end side of the file by the side grip portion 50.

As described above, when the gripping of the pile 200 by the side grip unit 55 is completed, the pile construction step 330 of constructing the pile is performed.

The pile construction step 330 includes a file setting step 331 for aligning and setting the pile 200 to the construction position, and a vibration impact force applied to the pile 200 using the vibration direction regulation unit 60. ), a vertical vibration striking step (332) in which construction is performed by applying an impact force in the vertical direction, and a boom (110) of an excavator that supports the pile driver (10) in the process of constructing the pile (200) by the pile driver (10). ) and a bucket cylinder operation release step (133) to prevent external force from being transmitted in the lateral direction to the pile (200) being constructed by the rotation of the bucket cylinder (111) installed thereon.

The pile construction method of the pile driver will be described in more detail through the action of the pile driver capable of vertical construction according to the present invention configured as described above.

First, in order to construct a pile, the coupler and coupling bracket 11 coupled to the boom 110 of the excavator 100 and the bucket cylinder 111 installed thereon are coupled. In this state, the pile 200 to be constructed is gripped using the side grip unit 50 installed on the vibrating body 41.

In performing the file gripping step 320 of gripping the file using the side grip unit 50, the file 200 is held using the swing unit 20 and the tilting unit 70, as shown in FIGS. 4 and 5. ) is placed, the posture of the vibrating body 41 is adjusted so that the file 200 can be easily gripped by the side grip portion 50. That is, the drive gear 23 is driven by the drive motor 24 installed on the driver housing 12 or the support member 15 to rotate the linker 22 engaged therewith, thereby moving the driver housing 12 to a predetermined position. Rotate by angle.

In addition, the driver housing 12 is tilted by operating the tilting cylinder 71 of the tilting unit 70 to rotate the support member 15 coupled by the coupling bracket 11 and the hinge shaft 11a at a predetermined angle. With the file 200 placed in this state, the file 200 is gripped using the side grip portion 50.

This can improve the workability of the pile device because there is no need to move and install the vibrating pile using separate equipment such as a crane, such as a vibrating pile driver for conventional pile construction.

In particular, when holding the file 200, as shown in FIG. 6, the side grip portion 50 is supported on the vibrating body 41 and is attached to the first and second side grip members 51 and 52 that protrude toward the front side. Since the pile 200 to be constructed can be gripped from the side, the boom of the excavator does not need to be relatively long for construction of the relatively long pile 200. This cannot improve the constructability and workability of the pile.

When the gripping of the pile 100 is completed as described above, the pile 200 is moved to the construction position and then the construction angle of the pile 200 is adjusted using the swing unit 20 and the tilting unit 70 as described above. Adjust.

In this state, the pile is constructed by vibrating the vibrating body (41) using the vibration generating unit (40). When constructing the pile 200, that is, performing the pile construction step 330, the vibrating body 41 of the vibration generating unit 40 vibrates with respect to the driver housing 12 by the elastic support members 35. In this way, the vibrating body 41 is guided by the vibration direction regulation unit 60 and vibrates in the vertical direction, that is, in the vertical direction of the pile 100 to be constructed. The guide rollers, which are the following members 65 and 66 installed on both sides of the vibrating body 41, move along the first and second guide members 61 and 62, thereby limiting the degree of freedom of vibration and causing the pile 200 to move. A vertical vibration striking step (132) of applying an exciting force in the vertical direction is performed.

In this vertical vibration striking step 132, when constructing the pile 100, it is possible to prevent the component force of vibration acting on the pile 200 from being generated through the vibrating body 41 and the side grip portion 50. In addition, since the load of the side grip portion 50 and the vibrating body 41 is applied to the pile in the vertical direction, the striking force can be increased.

The pile driver (10) with a precision vertical construction system according to the present invention has a vibrating body (41) suspended in the driver housing (12) by an elastic support member (35), so it vibrates even if the elastic support member (35) is damaged. It is possible to prevent the main body 41 from being separated from the driver housing 12.

On the other hand, the pile driver capable of vertical construction allows construction of the pile 200 while being coupled to the coupling bracket 11 by the boom 110 of the excavator 100 and the cylinder 111 installed thereon, so the pile ( As 200) is inserted, the boom of the excavator is lowered together and an external force is received in the outward direction. Therefore, the driver must finely manipulate the cylinder to maintain a horizontal state, but there are practical limitations to this operation.

However, the cylinder 110 installed on the boom provides automatic fluid to operate the bucket cylinder 111 by operating the solenoid valve 93 by the control unit of the cylinder deactivation unit 80 while the pile 20 is being constructed normally. By returning to the tank through the first and second branch pipes (91) and (92), the rod of the bucket cylinder (111) is freely drawn in and out of the cylinder body (112), and the pile (200) is moved by the rod of the bucket cylinder (111). External force is not applied in the lateral direction with respect to the construction direction. (Bucket cylinder operation deactivation stage)

As described above, the pile driver capable of vertical construction according to the present invention and the vertical construction method of piles using the same regulate the direction of vibration so that the vibrating body can be vibrated in the vertical direction, so that the exciting force acts in the vertical direction of the pile. The efficiency of pile construction can be maximized.

In addition, when constructing piles using a pile driver capable of vertical construction mounted on a boom equipped with an excavator's cylinder, the bucket cylinder installed on the excavator's boom and combined with a coupling bracket prevents the pile from receiving external force in the lateral direction, enabling precise construction. It becomes possible.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will understand that various modifications and other equivalent embodiments are possible therefrom. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the attached registered claims.

The pile driver capable of vertical construction according to the present invention and the vertical construction method of piles using the same are applicable to driving or rock crushing.
