Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pile erection device that erects a long object such as a pile placed horizontally at an arbitrary angle.

[0002]

[Prior art]

 Conventionally, a well-known inclined hoist has been used for building long piles and the like.

[0003] This inclined hoist is constructed by hoisting a hoist with a crane, attaching a fixed sling wire attached to the hoist, and a moving wire pulled out from the hoist drum to a two-point hanging piece of a pile, and extending the moving wire. It builds a stake at an arbitrary angle.

A method is also known in which a main hook and an auxiliary hook of a crane are used to attach a slinging wire to a two-point hanging piece of a pile and erect it.

[0005]

[Problems to be solved by the device]

 The former inclined hoist has a heavy hoist weight of 5 tons, and the crane's hoisting load increases accordingly.

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

[0007] Further, since it is electric, the cable curing is troublesome and dangerous.

In addition, since the winch capacity of the hoist is small, the speed is slow because the capacity is increased by using the pulley to increase the number of wires.

In addition, since the pulley diameter is small and the wire is long, it causes repulsion, and there is a case where it cannot be hoisted down due to entanglement.

On the other hand, in the latter method, there is a possibility that the crane boom may be unloaded from the top sheave if it gradually becomes inclined and starts to be angled after the suspension.

Further, the crane boom is twisted due to a change in load on the main hook and the auxiliary hook, which is dangerous.

An object of the present invention is to provide a pile erection device having a simple structure, lightweight, easy to operate and safe.

[0013]

[Means for Solving the Problems]

 According to the present invention, a base whose upper end is suspended from a main hook, a bell crank pivotally attached to the lower end of the base, and a connecting portion and the other end of a fixed sling wire provided at one end of the bell crank are provided. And a sheave for the movable sling wire provided.

It is preferable that the base is provided with a stopper that regulates a left-right rotation angle of the bell crank.

Further, the movable sling wire is connected to the auxiliary hook.

[0016]

[Action]

 In the pile erection device configured as described above, when the pile is erected, the upright side hanging piece of the pile placed horizontally is slid on the fixed wire, and the downhill side hanging piece of the pile is slung on the movable sling wire. .

Next, the device is hoisted, and the movable sling wire is paid out in accordance with the slant angle of the pile to erect the pile at a predetermined angle.

[0018]

【Example】

 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 erection device, generally designated by reference numeral 1, includes a pair of side plates 3 and bosses 4, 4 on the upper ends of the side plates 3, 3. It is composed of an upper pin 5 supported by a lower end and a lower pin 6 supported by a lower end thereof. The lower pin 6 is rotated by a bell crank having an opening degree α of, for example, 120 degrees. It is supported freely.

The bell crank 10 includes 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. ing.

The hook pin 12 is connected with a wire connector 13 which is a connecting portion of a fixed sling wire 21 (FIG. 5), and the sheave pin 14 is rotatably provided with a sheave 15 for a movable sling wire 24 (FIG. 5). It is supported.

Further, the base 2 is provided with a stopper 7 protruding from the base 2 to lock the bell crank 10 from rotating to the left and right at a rotation angle β (for example, 60 degrees).

Next, referring to FIGS. 5 and 6, a manner of building the pile P will be described.

The main hook 20 is hooked on the upper pin 5 of the pile erection device 1, and the hook pin 12 is connected to the upper end of the fixed sling wire 21. On the other hand, the movable sling wire 24, the upper end of which is hooked on the auxiliary hook 23, is hung down via the sheave 15.

At the time of building the pile P, the lower ends of the fixed sling wire 21 and the movable sling wire 24 are respectively hung on the two-point hanging pieces 22 and 25 provided on the horizontally placed pile P at two points.

Then, the crane is operated to lift the hanging piece 22 to the height H and the hanging piece 25 to the height H1. This is done by paying out the movable sling wire 24 by the difference H2 between the height H and the height H1, and the pile P is tilted upward on the side of the hanging piece 22 by the tilt angle θ. Therefore, by adjusting the difference H2, the pile P can be erected at an arbitrary inclination angle θ.

[0027]

[Effect of device]

 Since the present invention is configured as described above, it can be provided at a low cost with a simple and lightweight structure.

Moreover, the building operation can be performed easily and safely.
