BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a configuration of a position control apparatus for a heavy object according to an embodiment of the present invention; FIG.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

Hereinafter, an apparatus for controlling a position of a heavy object according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view of a structure of a position control device for a heavy object according to an embodiment of the present invention. In the embodiment of the present invention, a case where a plurality of pipes are buried in a ground will be described as an example.

As shown in FIG. 1, assuming that the first pipe 10, which is the first weight, and the second pipe 20, which is the second heavy weight, are connected to each other to be buried in the ground, 1 < / RTI >

It is preferable that at least one first sensor 15 is installed in the first pipe 10 in order to ensure the accuracy of the assembly position.

The second sensor 25 is installed at the other end of the second pipe 20 assembled with the first pipe 10 and the second sensor 25 of the same number as the first sensor 15 is connected to the second pipe 20, (20). For example, if two first sensors 15 are installed in the first pipe 10, two second sensors 25 are also installed in the second pipe 20.

It is preferable that the first sensor 15 and the second sensor 25 are disposed to face each other at the same positions of the pipes 10 and 20 in a one-to-one correspondence.

As described above, the first sensor 15 and the second sensor 25 form a single pair. When the assembled positions of the first pipe 10 and the second pipe 20 coincide with each other, The sensor 15 and the second sensor 25 are positioned on a straight line or contact each other to output a sensing signal.

The first sensor 15 and the second sensor 25 may be implemented by a contact sensor, an optical sensor, or the like, and may be designed to be easy to attach and detach, such as a magnet.

The notification unit 30 is connected to any one of the first sensor 15 and the second sensor 25 so that the first sensor 15 and the second sensor 25 are positioned on a straight line or in contact with each other And informs the operator that the assembled positions of the first pipe 10 and the second pipe 20 coincide with each other based on the sensing signal outputted.

At this time, when the notification unit 30 is connected to the first sensor 15, if the first sensor 15 is composed of two sensors, two first sensors 15 are connected to one notification unit 30 Or the notification unit 30 may be connected to the two first sensors 15, respectively. Here, when both the first sensors 15 are connected to the one notification unit 30, the notification unit 30 may detect that only the first sensor 15 receives the detection signals from the first sensor 15, The controller 15 informs the operator that the first sensor 15 and the second sensor 25 are located on a straight line or are in contact with each other.

When the first sensor 15 and the second sensor 25 are positioned on a straight line or contact with each other and output a sensing signal, the notification unit 30 having the above- The controller 10 lights up the lamp or generates an alarm to inform the operator that the assembly positions of the first pipe 10 and the second pipe 20 coincide with each other.

Thus, the notification unit 30 notifies the outside that the first sensor 15 and the second sensor 25 are located on a straight line or are in contact with each other through the lamp, the speaker, etc., And the assembled position of the second pipe 20 coincide with each other.

2 is a view for explaining an operation of a position control apparatus for a heavy object according to an embodiment of the present invention.

First, when the first pipe 10 and the second pipe 20 are assembled together and buried in the ground, a plurality of (for example, two) first sensors 15 are provided at one end of the first pipe 10, A plurality of (for example, two) second sensors 25 are installed at the other end of the second pipe 20 which is assembled with one end of the first pipe 10.

After the first sensor 15 and the second sensor 25 are installed in the first pipe 10 and the second pipe 20 as described above, the second pipe 20 is moved using a crane The second pipe 20 is positioned at the assembled position of the first pipe 10.

At this time, when the second pipe 20 is positioned at the assembled position of the first pipe 10, the first sensor 15 and the second sensor 25 are positioned on a straight line or contact with each other, The notification unit 30 lights the lamp according to the detection signal or generates an alarm to inform the operator that the second pipe 20 is located at the assembled position of the first pipe 10. [

Thus, by matching the mounting positions or the assembling positions of the heavy objects to be mounted or assembled by using the sensor, the heavy objects can be positioned quickly or accurately at the mounting or assembling positions, and safety accidents or equipment accidents can be reduced.

The position control apparatus for a heavy object of the present invention is not limited to the above-described embodiments but can be variously modified and embraced within the scope of the technical idea of the present invention. For example, in the embodiment of the present invention, the position of a heavy object is controlled using a sensor, but the position of a heavy object may be controlled using a laser or the like.
