Description

The utility model relates to X-ray inspection of welded joints by portable X-ray machines, namely, devices for mounting portable X-ray machines during radiographic control, and can be used to control welded joints of metal structures and pipelines with a diameter of 32 to 450 mm when the controlled object is at a height from 0 to 1200 mm from the ground level (site).

Known devices for mounting, holding and positioning measuring instruments (Patent RU No. 73148, IPC Н05К 7/18, publ. 05/10/2008 in bull. No. 13, as well as Patent RU No. 19368, IPC B01L 9/00, publ. 27.08. 2001 in Bulletin No. 24) containing a base, a rack and an attachment unit of the device.

However, these devices are intended for use in laboratory conditions or require a flat hard surface and are focused on the specific dimensions of the fixed equipment.

A tripod for an X-ray machine is also known (Patent RU No. 2578398, IPC G12B 9/00, published March 27, 2016 in Bull. No. 9), including two identical holders, each of which is made with the possibility of fixing it on the body of the X-ray apparatus and connected, with at least one magnet configured to detachably attach to the surface of the translucent object, each holder being movably connected to a U-shaped handle rotatably relative to its connection with the holder.

The disadvantages of this tripod are the lack of reliability associated with the need to install safety elements, as well as the difficulty of performing the radiographic control process, since to control the entire object, it is necessary to bring the handles each time, disconnecting the magnets from the surface of the object, remove the safety element, move it to another control place .

Also known is a tripod for equipment installation (Patent RU No. 2673446, IPC F16M 11/16, F16M 11/32, F16M 11/36, published on November 26, 2018 in Bulletin No. 33), containing a head with three side faces that are fastened to three sliding legs with fixing bolts, with the possibility of rotation around them and sliding along the side faces, the legs are made telescopic and consist of two parts, external and internal, and are made of aluminum rectangular shapes, each leg on top welded with aluminum sheet and has a protrusion with an opening to which the platform table is attached to accommodate equipment, with limiters for legs vertically and deflected on the head on each side to the left and right of the leg, there are holes in the lower part of the outer legs around the perimeter that are sealed from the inside , the same seals are inserted externally into the holes in the upper part of the inner legs, while the extension of the inner leg is fixed through the seal with a threaded the retainer, which is located on the wide side at the bottom of the outer legs, the inner legs are welded from the bottom and have a threaded hole for screwing the tip, a sleeve is inserted between the outer wall of the outer leg and the inner wall of the head, which prevents them from collapsing when the fixing bolt is twisted, between the faces of the head and fluoroplastic washers are laid on the legs to reduce friction, and a liner with a hook is fixed in the middle of the head to fasten the screed to the supporting surface or to hang a load of stability, and the liner is attached to the head with the same mounting bolts that attach the telescopic legs.

The disadvantage of using screw-in tips at the end of the leg is the small footprint, which narrows the scope due to the impossibility of use on loose and loose surfaces, as well as on surfaces with a hard and slippery surface.

The closest is a tripod instrument for field measurements (Patent RU No. 129219, IPC G01D 11/30, published on 06/20/2013 in bull. No. 17), containing a rack, a device for fixing the tripod and the mounting unit of the detector device, while the rack is made from a composite steel tube, to the lower end of which a rod tip is fixedly mounted for deepening into the soil, the tripod fixation device contains four rod stops with threaded connection at the junction of the tripod tube and tip, the instrument mounting unit consists of a double clamp that allows changing the detector mounting height along the stand, and the clamp, corresponding to the diameter of the detector and allowing you to change the angle of inclination of the vertical axis of the detector by rotating the clamp at its fixation point in the clamp.

The technical tasks of the proposed utility model are the creation of a simple and reliable tripod design, which allows to improve the quality of x-ray images and radiographic control in general, expanding the range of controlled diameters of pipelines, as well as reducing the time for preparatory work.

Technical problems are solved by a universal tripod for portable x-ray machines, containing a rack made of steel pipe, a device for fixing a tripod, and a device mount.

Universal tripod for portable x-ray apparatus includes a stand 1 (Fig. 1, 2) of a steel pipe, a device for fixing the tripod 2, which is made of two angles superimposed on each other and rigidly located relative to each other at an angle of 90 °, for example, connected between each other by welding. The attachment point of the device is made in the form of a platform 3 (Fig. 1, 3) with a square hole 90 × 90 mm with a flange 4 with a height of 35 mm, which is sufficient to accommodate a portable x-ray machine. A square hole of 90 × 90 mm allows you to set the x-ray machine vertically relative to the controlled object and to control the lower part of the welded joint (Fig. 10). Moreover, the platform 3 (Fig. 1, 3) is connected to the slider 5 (Fig. 1, 4) using a hinge device consisting of a fixed axis 6 and a rotary sleeve 7 (Fig. 1, 5), and is mounted on it with the possibility of rotation platform 3 (Fig. 1) relative to the rack 1 to the controlled object at an angle of up to 45 ° and the possibility of fixing in the required position using the lock nut 8 (Fig. 1, 4). In this case, the slider 5 has two threaded holes 9 and is mounted on the rack 1 using the clamp 10 with the possibility of limited movement up and down.

Universal tripod for portable x-ray apparatus works as follows.

A universal tripod is a metal stand 1 (Fig. 1) made of a pipe with a diameter of, for example, 27 mm, 1200 mm long, and a tripod fixing device 2 made of two angles superimposed on each other and rigidly arranged relative to each other by welding at an angle 90 °, for example, angles of size 50 × 50 × 5 mm, length 480 mm. The stand 1 and the fixture for fixing the tripod 2 are rigidly interconnected by welding.

On the platform 3 of the tripod, made of steel sheet, for example, 3 mm thick, having overall dimensions, for example, 350 × 150 mm, with a flange 4 (Fig. 1, 3) 35 mm high and a square hole 90 × 90 mm, is portable x-ray machine. If it is necessary to control the lower part of the welded joint, the x-ray apparatus is installed vertically relative to the controlled object in a square hole of 90 × 90 mm (Fig. 10). The platform 3 is located on a hinge device consisting of a fixed axis 6 (Fig. 1, 3) with a length of, for example, 163 mm and a diameter of 18 mm, with a thread on its free end (16 mm thread, 80 mm long), and a rotary sleeve 7 (FIG. . 1, 5), for example, with a diameter of 34 mm and a length of 350 mm. The platform3 is attached to the rotary sleeve 7 by the lower part by welding. For ease of operation during radiographic control, the hinge device allows you to rotate the platform 3 relative to the rack 1 to the controlled object, for example, a pipeline, at an angle of up to 45 ° (Fig. 8, 9) and fix it with a lock nut 8 (Fig. 1, 4). Thus, the necessary rotation of the portable X-ray apparatus is provided, the accuracy of control and the reliability of the results are increased. The thread at the end of the fixed axis 6 serves to fix the angle of rotation of the platform using the lock nut 8.

The platform 3 (Fig. 1) is connected by a hinge device to a slider 5, which is a pipe with a diameter of, for example, 35 mm, 145 mm long, has two holes 9 (Fig. 1, 4) with a thread, for example, 12 mm for fixing its position, fixing on the rack 1 using a clamp 10. The slider 5 is rigidly connected to the fixed axis 6 by welding. Thus, it is possible to raise or lower the platform 3 with the x-ray apparatus to the required height along the rack 1 (Fig. 1) and fix it with a clamp.

The proposed universal tripod allows you to install portable x-ray machines in various spatial positions relative to the welded joint of metal structures and pipelines with diameters from 32 mm to 450 mm at a height of up to 1200 mm from the ground (platform).

The universal tripod for portable x-ray machines is a simple and reliable design. The use of the proposed universal tripod can improve the quality of x-ray images and radiographic control in general, allows you to expand the range of controlled diameters of the pipelines, as well as reduce the time for preparatory work during x-ray inspection of welded joints.
