[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile mounting apparatus for erecting a long object such as a pile placed horizontally at an arbitrary angle.

[0002]

2. Description of the Related Art Heretofore, a known inclined hoist or the like has been used for installing a long pile or the like.

[0003] The inclined hoist is constructed by lifting a hoist with a crane, attaching a fixed slinging wire attached to the hoist and a moving wire drawn from the hoist drum to a two-point hanging piece of a pile, and extending the moving wire.
The pile is built up at an arbitrary angle.

There is also known a method in which a sling wire is attached to a two-point hanging piece of a pile by using a main hook and an auxiliary hook of a crane to erect it.

[0005]

[Problems to be Solved by the Invention] The former inclined hoist has a heavy hoist of 5 tons, and the lifting load of the crane is correspondingly increased.

Further, a large-capacity power supply of 200 V is required.

[0007] In addition, due to the electric power, curing the cable is troublesome and dangerous.

In addition, since the hoist has a small winch capability, the speed is slow because the pulley is used to increase the number of wires and increase the capability.

Further, since the pulley diameter is small and the wire is hanging on a long object, there is a rebound, and there is a case in which the wire cannot be lifted and lowered.

[0010] On the other hand, in the latter method, there is a danger that the crane boom will be disconnected from the top sheave if it becomes gradually inclined from the time of suspension and starts to form an angle.

In addition, a change in the load on the main hook and the auxiliary hook causes the crane boom to be twisted, which is dangerous.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pile mounting device which is simple in structure, lightweight, easy to operate and safe.

[0013]

According to the present invention, a base having an upper end suspended from a main hook, a bell crank pivotally attached to a lower end of the base, and a fixing provided at one end of the bell crank are provided. A connecting portion for the slinging wire and a sheave for a movable slinging wire provided at the other end.

It is preferable to provide a stopper on the base for restricting the left and right rotation angles of the bell crank.

The movable sling wire is connected to the auxiliary hook.

[0016]

In the pile construction device constructed as described above, when the pile is constructed, the upwardly inclined suspension piece of the pile placed horizontally is used as a fixed wire, and the downwardly inclined suspension piece is used as a movable sling wire. Sling each.

Next, the apparatus is lifted, and the movable slinging wire is paid out according to the oblique angle of the pile to erect the pile at a predetermined angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 4, a vertical base 2 of a pile-building device, generally designated by reference numeral 1, has a pair of side plates 3 and upper ends of the side plates 3, 3 with bosses 4, 4 interposed therebetween. An upper pin 5 supported at the lower end and a lower pin 6 supported at the lower end of the lower pin 6 are rotated by a bell crank having an opening degree α of 120 degrees, for example, as a whole. It is freely supported.

The bell crank 10 comprises a pair of side plates 11, a hook pin 12 supported at one end of the side plates 11, 11, and a sheave pin 14 supported at the other end. .

The hook pin 12 is connected to a wire connector 13 which is a connecting portion of a fixed slinging wire 21 (FIG. 5). The sheave pin 14 is connected to a movable slinging wire 24.
(FIG. 5) is rotatably supported.

A stopper 7 is provided on the base 2 to stop the bell crank 10 from turning left and right at a turning angle β (for example, 60 degrees).

Next, referring to FIG. 5 and FIG. 6, the manner in which the pile P is installed will be described.

The main hook 20 is hung on the upper pin 5 of the pile erection device 1, and the hook pin 12 is connected to the upper end of a fixed slinging wire 21. On the other hand, the auxiliary hook 23
The movable slinging wire 24 with the upper end hooked to the sheave 1
Hanging through 5.

When the pile P is installed, the fixed slinging wire 21
Each of the lower ends of the movable slinging wires 24 is hung at two points on two-point hanging pieces 22 and 25 provided on a pile P placed horizontally.

Then, the crane is operated and the hanging pieces 22
To the height H, and the hanging pieces 25
Hang it on 1. This is performed by feeding out the movable slinging wire 24 by the difference H2 between the height H and the height H1, and the pile P is tilted upward on the hanging piece 22 side by the tilt angle θ.
Therefore, by adjusting the difference H2, the pile P can be erected at an arbitrary inclination angle θ.

[0027]

[Effects of the Invention] Since the present invention is configured as described above, the structure can be simplified and reduced in weight and provided at low cost.

Further, the mounting operation can be performed easily and safely.
