Abstract

PURPOSE:To pull out a pile by a method in which an arm to grasp a pile is attached to the tip of the arm of an oil-pressure power shovel and operated by an actuator for driving a bucket. CONSTITUTION:An oil-pressure pile drawer B is attached through a base arm pin 17 to the tip of the arm 21 of a base machine, e.g., oil-pressure power shovel. A base bucket cylinder pin 18 is also connected to the tip of the bucket cylinder 19 of the base machine to enable a chuck 2 to open or close. Pile drawing operation can thus be made easier and the period of construction can also be shortened.

Description

[Detailed Description of the Invention] This invention relates to a hydraulic pile handling machine, and regardless of the type or size of the conventionally used base machine (A),
By combining this, the construction period of the navigation method can be shortened,
The aim is to save labor, prevent pollution, reduce costs, and stabilize underground soil.

In the conventional pile construction method, the pine piles (C) are bent or the piles (C) are bent.
) When driving the pile (C), the pile (C) is often driven unevenly into soft areas due to differences in the soil quality underground. For this reason, the driving of the casing also hits the pile (C), causing problems in driving, and the driving of the edge-cutting sheet pile in the vibrohammer technique also hits the pile (C), making driving difficult. As a result, when it was being handled by a crane, it broke off deep underground, and when the casing was driven in, the pile hole with the pile (C) in the center collapsed because the casing was driven in while sending compression work, and the soil stabilizer was removed. Injection becomes difficult. Especially in urban areas and adjacent areas such as buildings, if soil stabilizer is not injected every time a pile (C) is removed, ground subsidence will occur in adjacent areas outside the construction area due to the effects of earth pressure. do.

The hydraulic pile uill (B) according to the present invention is manufactured by the base machine (A
> By changing the position and size of each part of the hydraulic pile handling machine (B) depending on the type and size of the pile, navigation work can be carried out according to the length, thickness, and geology of the pile (C). I can do it. also,
Conventional pile handling methods such as the casing technique and the vibrohammer technique cause pollution problems such as vibration and noise, but the hydraulic pile handling machine of the present invention does not have these concerns.

Furthermore, conventional construction methods require a large amount of equipment such as cranes, compressors, generators, power shovels, etc., and 4.5 people are required for on-hand work other than operation, resulting in high costs and a wide range of work. Hydraulic navigation aircraft (B
) allows the loading of vehicles to be carried out continuously in parallel with the navigation work, resulting in labor savings and cost reductions in terms of personnel and equipment. In other words, it is loaded as is in the state (b) or (c).

To show an example of actual performance of the hydraulic pile handling machine (B) according to the present invention, in the work of pulling out pine piles (C) for the foundation of a gas tank at a certain factory,
40 to 120 pine piles 9 meters long in geological river sand per day
Books can be processed, and the process is being carried out with one base machine (A), one operator, and one on-hand worker.

The structure of the hydraulic pile and bale machine (B) according to the present invention and the base machine (
The combination relationship with A) is shown in the drawing as follows.

The size and type of base machines (A
), the base arm pin (18) of the hydraulic pile machine (B) is attached to the tip of the base machine arm (21).
The base packet cylinder pin (17) is attached to the tip of the packet cylinder (19) of the base machine (A).

The base machine hydraulic pressure (20) is connected to the hydraulic pipe (14) of the hydraulic pile f& machine (B) with a high-pressure hose, and the hydraulic pile rear machine (B) is operated by operating the steering wheel on the driver's cab. When the piston rod (11) of the hydraulic pile Fii (B) is extended by operation, the piston rod (11) is moved from the piston arm (B) to the chuck center pin (7) around the piston pin roller (9). ) is transmitted evenly, it grips the pile head (C') inside the center of the chuck (2). The extending stroke of the piston rod is such that no load is applied to the chuck arm (4) when the chuck arm (4) is idle. When the piston rod (11) contracts, the chuck arm (4) expands and releases the pile head (C"). The piston roller guide (1
0) is important for transmitting the vertical and horizontal movements of the piston pin roller (9) in a certain direction. The position of the arm with plate (5) may be lowered depending on the thickness of the pile (C) and soil quality. If lowered, lengthen and thicken the four piston arms (B). Lowering the arm with plate (5) increases the force on the chuck (2), so make the chuck pin (3) thicker and tighten the chuck (2).
If the pile cap (C') is not made long, the pile cap (C') will be crushed, so the chuck power (1) should be increased.

As described above, by changing the structure of the hydraulic pile cutting machine (B) according to the present invention and the position and size of each part, it becomes easy to handle the piles according to the shape, posture, and geology of the piles (C). .
