Description

The proposed utility model relates to devices for attaching x-ray devices to objects of control.

A known device for fixing an x-ray apparatus at the object of transmission - the pipe according to the patent of the Russian Federation No. 154800, publ. 09/10/2015, comprising holders made to be mounted on the body of an X-ray apparatus and connected to magnets configured to detachably attach to the surface of the ferromagnetic pipe, the holders are movably connected to two U-shaped handles, the U-shaped handles being made to rotate relative to places of their connection with holders.

The disadvantage of this design of the device for fixing the x-ray apparatus on the pipe is that it is not intended for x-ray radiography of transverse welds of small diameter pipes due to the small radius of curvature of the surface of these pipes and the small force of the magnets to be pressed against such surfaces. In addition, the magnetic device can only be used on pipes made of ferromagnetic materials.

Closest in its technical essence to the proposed utility model is a device for fixing an X-ray apparatus on a pipe according to the patent of the Russian Federation No. 166257, publ. 11/20/2016. The device comprises an x-ray apparatus holder, a rod and a clamp. The bar is made in the form of a straight and curved parts with two pillows fixed on the curved part. The clamp is equipped with a movable slider with an opposite pillow, while the clamp and the holder of the x-ray apparatus are fixed to the straight part of the rod using the movable clamp sleeve and the holder sleeve. The holder sleeve is made with the possibility of stepwise movement along the straight part of the rod.

The disadvantage of this device is the need for pre-installation with subsequent fixation on the rod of the movable sleeve with an opposite slider fixed to it with a cushion, depending on the diameter of the "translucent" pipe. Another design disadvantage of the device in question is that it cannot be installed on pipes laid along closely spaced objects, such as walls. Also, this device cannot be used for radiographic inspection of a weld on pipes with radii exceeding the radius of the curved part of the rod.

The objectives of the proposed utility model are as follows:

- expanding the scope of the device for fixing the x-ray apparatus, i.e. use regardless of the material of the control object, its shape and size;

- increase in labor productivity - no need to pre-configure the device for the diameter of the pipe;

- improving the reliability of mounting of the x-ray apparatus.

To solve the tasks, a device for fixing the X-ray apparatus at the test object (hereinafter referred to as the device), in particular on the tube, which, like the closest one selected as a prototype, includes a rod, a manual clamp, consisting of movable and fixed parts, and a holder x-ray apparatus, mounted on the rod using a movable sleeve of the holder, made with the possibility of movement along the rod with subsequent fixation.

Unlike the prototype, the hand clamp is fixedly mounted on the front end of the rod using a bracket and is supplemented by a Gall chain attached at one end to the front end of the movable part of the hand clamp with the possibility of covering the test object with the free end of the Gall chain with a tight fit and subsequent fixing of the nearest link of the Gall chain by a hook located at the front end of the fixed part of the hand clamp.

The essence of the utility model is that the presence of a Gall chain in the device allows you to fix the X-ray machine on shaped pipe elements such as a tee, elbow, tie-in, etc., install it on pipes passing close to a wall or other closely located object, since the gap required for fixing the device is the thickness of the link of the Gall chain (~ 10 mm). Due to the presence of a Gall chain, the device can be reliably mounted on pipes of any profile (triangular, rectangular, round, octagonal, etc.) without first setting it to the external size of the pipe or other control object. When the device is installed in a new position for the subsequent radiographic image, it is not necessary to remove the device from the object, but just loosen the tightness of the Gall chain using the manual clamp, rotate it, or move the Gall chain with the device along the control object and fix it in the new selected position. In this case, the length of the Gall chain in all cases must exceed the length of the perimeter of the control object in the place of attachment of the device.

The essence of the utility model is illustrated in the drawing:

FIG. - General view of the device for fixing the x-ray apparatus at the test object - the pipe.

The device 1 for fixing the x-ray apparatus 2 at the test object - pipe 3 with a weld 4 contains:

5 - rod;

6 - bracket;

7 - manual clamp;

8 - movable part of the manual clamp;

9 - fixed part of the manual clamp;

10 - holder of the x-ray apparatus;

11 - movable sleeve of the holder;

12 - Gall chain;

13 - hook;

14 - an adjusting screw;

15 - lever-latch.

To carry out radiographic inspection of the weld 4 on the radiograph tube 3 behind the weld 4, place and attach the cassette with the x-ray film, then the device 1 for fixing the x-ray apparatus 2 is mounted on the pipe 3 near the weld 4. For this, pipe 3 is covered with the free end of the Gall chain 12, which the other end is attached to the front end of the movable part 8 of the hand clamp 7. The free end of the Gall chain 12 is hooked 13, which is located on the front end of the fixed part 9 of the hand clamp 7. The hook 13 is hooked the closest link to it is the tensioned Gall 12 chain. When the rear ends are pulled together by the movable 8 and the fixed 9 parts of the hand clamp 7, the required tension of the Gall 12 chain wrapped around the radiographed tube 3 is ensured by the hand, which leads to a firm fixation of the device 1 on the tube 3. The magnitude of the force the tension of the Gall chain 12 is adjusted by rotating the adjusting screw 14 located at the rear end of the fixed part 9 of the manual clamp 7.

The x-ray apparatus 2 is inserted and fixed into the holder 10 in such a way as to direct the radiation pattern of the x-ray apparatus 2 to the cassette with the x-ray film behind the weld 4. The movable sleeve 11 of the holder 10 with the fixed x-ray apparatus 2 is put on and fixed on the rod 5 in the selected position. Thus, the x-ray apparatus 2 is fixed on the test tube 3 and is ready for radiography of the weld 4.

At a safe distance from the x-ray apparatus 2, the exposure of the x-ray apparatus 2 is remotely turned on and an x-ray of the weld 4 is made onto the cassette with the x-ray film pre-installed behind the weld. Then remove the cassette with the exposed x-ray film from the test tube 3.

At the end of work with the first shot of the weld 4 from the device 1, remove the holder 10 with the installed x-ray apparatus 2, and then remove the device 1 from the pipe 3 by pressing the latch lever 15 located on the rear end of the movable part 9 of the manual clip 8. When In this case, the tension of the Gall chain 12 around the pipe 3 is weakened and it becomes possible to either remove the device 1 by first removing the hook 13 from the Gall chain or deploy the device 1 around the pipe 3 to take the next picture of the weld 4 in the new position of the X-ray apparatus 2 in accordance with the radiography procedure for pipe welds. This operation is completed by re-tightening the rear ends of the movable 8 and the fixed 9 parts of the hand clamp 7 with a hand until the click of the latch lever 15. The x-ray apparatus 2 is fixed on the pipe 3 in a new position and is ready for a second radiographic image of the weld 4.

Thus, the proposed utility model solves all the tasks.
