The present invention relates to a film position fixing device for a non-destructive inspection, and more particularly to a film position fixing device for a non-destructive inspection capable of fixing a film provided on a side opposite to a position of a radiation source for irradiating the inspection zone with non- About

In general, nondestructive testing is very useful for measuring the presence of internal defects such as welding conditions at various industrial sites where power plant construction sites, pipelines, and pressure vessels are manufactured. In addition, it can be inspected without damaging the object Which contributes greatly to the improvement of product stability and reliability.

The radiation irradiator used for the ordinary non-destructive inspection is a non-destructive inspection equipment which can inspect the internal defects of the structures such as pipes and steel pipes through radiography. The irradiation system consists of a container for shielding the radiation source, a controller for controlling the transmission of the radiation source, and a cable for providing the transmission path of the radiation source.

In the nondestructive inspection using a radiation applicator, the radiation source provided at the distal end of the cable is fixed to the inspection point, and then the film is attached to the outer surface of the object to be inspected and the controller is operated to irradiate the radiation.

Conventional film attaching method is performed by taping. In this method, it is difficult to adhere to the outer surface of the object to be inspected accurately due to the foreign object and temperature, and the film can not be adhered effectively due to the influence of the surrounding environment. There is a fear that it will not be obtained.

As described above, according to the present invention, the following effects can be expected.

The film can be adhered and fixed effectively, so that the preparation process for the non-mass inspection can be performed easily and quickly, and the reliability of the inspection result can be expected to be improved.

1 is a side view of a first embodiment according to the present invention.
2 is a side view of a second embodiment according to the present invention.
3 is a side view showing the use state of the second embodiment according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the film position fixing apparatus for nondestructive inspection according to the present invention is for fixing a film (F) adhered to a welded portion of a tube for nondestructive inspection by a radiation transmission method. The first embodiment includes a vertical member 100, a support member 200, a horizontal member 300, and a cover member 400.

The vertical member 100 is vertically arranged to support the horizontal member 300 and has a structure in which the length is configured to be stretchable and a clamp is provided at an upper end thereof.

In addition, the support member 200 is provided at a lower side of the vertical member 100 to support the vertical member 100 from the bottom, and is composed of a combination of a plurality of support rods. Each of the support rods is disposed in a tilted form for stably supporting the vertical member 100 and is connected to form a predetermined gap along the lower circumference of the vertical member 100 at its upper end, And an adsorption pad which can be adsorbed and attached to the basement.

In order to more reliably support the vertical member 100 in the structure of the vertical member 100 and the support member 200, it is also possible to detachably attach a weight having a predetermined weight to the lower end of the vertical member 100 have.

The horizontal member 300 is detachably fixed to the clamp and is configured to be stretchable in length. The front end of the horizontal member 300 is provided with a ball seat for engaging with the cover member.

Here, each of the vertical member 100 and the horizontal member 300 includes a large-sized pipe and a small-sized pipe. The large pipe is formed in a hollow pipe shape, and a screw hole is formed at one side thereof. And a screw is provided in a state of being screwed. By inserting the small-diameter pipe into the large-diameter pipe so as to be able to enter and exit the large-sized pipe, the small-diameter pipe is tightened and fixed by the tightening screw,
