Description

Device for fling pile}

The present invention relates to a file lifting mechanism, and more particularly, to a file lifting mechanism capable of safely lifting a file at a construction site.

Generally, at the stage of civil engineering foundation construction, a file construction is made to support a structure or a building by putting several files on the ground.

In order to construct a file used in a construction site, there are many cases in which a file needs to be lifted in various forms.

For example, a file lifting operation is indispensable when transporting a file, particularly when loading a truck, loading a barge, or unloading a file at a site, hitting a file at a construction site, Construction and stability are very important for lifting these files.

Various methods and apparatuses are proposed for lifting such a file. Among them, there is a hole sampling method as a representative method.

In the hole striking method, an upper portion of a file fixed on the ground is bundled in a lasso form using a wire, and then the wire is connected to a hook of a crane and is lifted.

However, when the diameter of the file is large or the length of the file is long, it is difficult to use the hole drilling method because it is very difficult to install the hole drilling method, and there is a problem that the file is locally damaged do.

In addition, when the knot of the wire is frequently loosened due to carelessness or negligence of the operator, especially when the soil or water is adhered to the outer circumference of the pile depending on the working environment or ice occurs due to the cold weather, Which causes the file to slip out of the wire, thus causing a high risk of a safety accident.

In order to solve the above-mentioned problem, in the prior art 1 (Korean Patent No. 10-1038453, filed in the same year), when a file is lifted at a construction site, the file is fastened to the top of the file by a bolt fastening method, A lifting mechanism that can be operated is disclosed.

However, since the bolt fastening method requires the operator to fasten the bolt after aligning the bolt fastening hole formed in the coupling body with the screw hole formed in the pile, the working time is delayed, resulting in a problem that the construction time is prolonged.

In particular, in the case of a steel pipe file, it is difficult to form a bolt hole.

In the present invention, in lifting a file at a construction site, a file can be safely lifted in a shorter time by lifting the file in such a manner that the lifting mechanism is not fastened to the file with a bolt, but is inserted or caught in the file. The present invention provides various embodiments of this file lifting method.

First, a first embodiment of a file lifting mechanism according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the overall shape of a file lifting mechanism according to a first embodiment of the present invention, and FIG. 2 is a perspective view showing a bottom surface of a lifting plate in a file lifting mechanism according to a first embodiment of the present invention .

1 and 2, a file lifting mechanism according to a first embodiment of the present invention includes a fixed hook 11 provided in a file 10, a lifting plate 20 fitted to the fixed hook 11, .

 Here, the file (10) is a structure used to stably support a structure or a building by being buried in the ground at the civil engineering foundation stage.

The fixing hook 11 is provided at the upper end of the pile 10 as the pail 20 is inserted. More specifically, the fixing hook 11 includes a horizontal extending portion 11a extending from the inner surface of the upper end of the pile 10 toward the center of the pile 10 to a predetermined length and a lower extending portion 11a extending downward from the end portion of the horizontal extending portion 11a And a vertical bent portion 11b bent vertically. The fixing hooks 11 are integrally joined to the pile 10 before bolting or welding.

These fixed hooks 11 are arranged at the same height along the inner surface of the pile 10 while maintaining a 90 degree spacing therebetween. Thus, when lifting the file through the lifting plate 20, the lifting plate 20 is engaged in all directions of the pile 10, so that the pile 10 can be reliably lifted.

However, in the present invention, four fixed hooks 11 are provided. However, at least two fixed hooks 11 are included in the present invention.

The lifting plate 20 serves as a medium for connecting and fixing the pile 10 to the lifting equipment 40 and is a structure for lifting the pile 10 in a stable and fixed manner.

The lifting plate 20 is formed in a disc shape smaller than the inner diameter of the pile 10. [ An insertion hole 21 is formed at the edge of the foot plate 20 so that the fixing hook 11 is inserted. Concretely, the foot plate 20 is formed with four fitting holes 21 in which the fixing hooks 11 are fitted at positions corresponding to the vertically bent portions 11b of the four fixed hooks 11.

The fitting hole 21 is a hole drilled in the thickness direction of the relief plate 20 in a rectangular shape having the same shape as the vertical bent portion 11b of the fixed hook 11. The fitting hole 21 is formed to be larger than the vertical bent portion 11b of the fixing hook 11 so that the fixing hook 11 can be easily engaged.

A connecting body 22 connected to a hook (41 in FIG. 3) of the lifting equipment (40 in FIG. 3) is provided on the upper surface of the lifting plate 20.

Therefore, the hook 41 of the lifting device 40 is inserted into the connection hole 22a, and the pile 10 can be easily supported and lifted using the lifting device.

When the lifting plate 20 is lifted up by the lifting device 20, it is naturally tilted and easily enters into the pile 10 without being interfered with the fixed hook 11 provided on the pile 10, There is a way to be.

To this end, an eccentric weight portion 23 is formed on one edge of the pulling plate 20.

Specifically, the eccentric weight portion 23 is formed so that one of the eccentric weight portions 23 is heavier than the other, that is, the thickness of the eccentric weight portion 23 is thicker than the other.

The lifting plate 20 is always inclined toward the eccentric weight portion 23 due to the difference in weight of the eccentric weight portion 23 during lifting so that the fixing hook 11 provided inside the pile 10 is kept in a state of being inclined, The user can easily enter the inside of the file 10. [

At this time, the coupling body 22 provided on the upper surface of the lifting plate 20 is not provided with the eccentric weight portion 23 and is eccentrically disposed at the center of the lifting plate 20 so that the lifting plate 20 is inclined, 10). ≪ / RTI > However, when the lifting plate 20 is lifted in combination with the pile 10, the force applied from the lifting equipment to the side of the pile 10 is eccentrically applied. As a result, it is not easy to pull out the pile 10 from the ground in order to lift the pile 10 buried in the ground. In addition, when the file 10 loaded on the ground is lifted to be buried in the ground, the file 10 is lifted by the weight of the file 10 in an inclined state, and the risk of a safety accident due to the fall of the file 10 And it is difficult to lift it perpendicularly to the ground, making it difficult to perform accurate landfilling.

The lifting plate 20 is easily inserted into the pile 10 while being connected to the hook 41 of the lifting equipment 40 without fastening the bolt at the construction site, The piles 10 and the lifting plate 20 are firmly engaged with each other by a simple operation of lifting the holes 21 in unison so that the piles buried in the ground can be easily lifted by using the lifting equipment 40 do.

Hereinafter, an operation state of the file lifting mechanism according to an embodiment of the present invention will be described.

When the hook 41 is lifted, the lifting plate 20 is naturally lifted up to the eccentric weight portion 23 side.

Referring to FIG. 3B, the lifting plate 20 enters the inside of the pile 10 in a tilted state. At this time, in a state in which the lifting plate 20 is inclined, it enters the pile 10 through a space between the fixed hook 11 and the fixed hook 11, which is not provided with the fixed hook 11.

Thus, even if the diameter of the lifting plate 20 is larger than the diameter of the end portions of the four fixed hooks 11, the lifting plate 20 can be fixed to the fixed hook 11 while maintaining the inclined posture at the time of entering the pile 20, And the fixed hooks 11 so that they can easily enter into the pile 10. [

3C, when the lifting plate 20 is inserted into the pile 10, the fitting hole 21 of the lifting plate 20 is aligned with the fixing hook 11 of the pile 10, When the equipment 40 is lifted up, the fixing hook 11 and the fitting hole 21 are fitted to each other, so that the lifting plate 20 is held in a state in which the pile 10 is fixedly supported.

Thus, the file 10 can be reliably connected to the lifting equipment 40 without being tilted or crashed.

3D, the pile 10 is lifted using the lifting equipment 40 with the pile 10 and the lifting plate 20 engaged.

At this time, due to the weight of the pile 10, the fixed hook 11 and the fitting hole 21 are firmly connected and connected without any special fixing means because a force larger than the weight of the pile 10 is applied from below to above The weight of the file 10 is applied downward so that the file 10 can be stably supported and lifted by using the weight of the file 10.
