    (54) DEVICE FOR ULTRASONIC CONTROL The invention relates to non-destructive testing means and can be used, for example, for pipeline inspection. A device for ultrasonic testing, containing a hollow rotating cylinder of an acoustically transparent material, an ultrasonic transducer located therein, an interacting layer of contact liquid with a cylinder in contact with the product C is known. A disadvantage of the known device is the low reliability of detecting defects. provided for the control of defects. The closest in technical essence to the present invention is a device for ultrasonic testing, containing a camera mounted on a fixed shaft, made in the form of a rigid annular rim and hermetically connected end disks tightly connected to it, at least one ultrasonic transducer placed in an acoustically transparent medium, and its interface with the inner rim surface of the acoustic lens 2J. A disadvantage of the known device is its fragility, due to the rapid abrasion of the contact surface. The goal is achieved in that the device is provided with an elastic tire covering the rim of an acoustically transparent material. The rim is made of polymethyl methacrylate. The tire is made of polyurethane, polyethylene or rubber compound. The acoustically transparent medium is a mixture of glycerol and water with solid particles, for example, graphite or disulfide G) Libden. Figure 1 shows the device a top view with a partial cut; figure 2 is a view of And figure 1; figure 3 section bb in figure 1 figure 4 - section bb In figure 3. The device for ultrasonic testing contains a camera 2 mounted on a stationary shaft 1, made in the form of a rigid annular rim 3 made of polymethyl methacrylate (registered trade name perspex) and end plates 4 and 5 hermetically connected to it.
    Chamber 2 contains at least one separately-combined ultrasonic transducer b with piezoplates 7 and 8 for controlling the cross section, as well as a second ultrasonic transducer 9 mounted on an acoustic lens 10 conjugated to transducers b and 9 and with the inner surface rim 3,
    An acoustic lens 10, made for example of nylon, with transducers is placed in an acoustically transparent medium (not shown), which is a mixture of glycerin and water with solid particles, for example graphite or molybdenum disulfide. The outer surface of the rim 3 has a barrel shape and is covered by an elastic tire 11 made of polyurethane, polyethylene or rubber compound.
    The stationary shaft 1 of the chamber 2 is mounted in the supporting elements 12 and 13 fixed on the underside 14 in the support 15 with the possibility of rotation around the axis 16, perpendicular to the axis 17 of the shaft 1,
    The support 15 is mounted on rollers 19 and 20 fixed on the bracket 18 and interacting with it by means of rolling elements 21. The chambers 2 are mounted with the possibility of rotation relative to the fixed shaft 1 on bearings 22 and 23 and sealed by seals 24 and 25, 26 and 27. The acoustic lens 10 with the converters b and 9 is elastically suspended on the shaft 1 by means of a frame 28 consisting of crossbars 29 and 30, rods 31 and 32, and a spring 33 that presses the lens 10 to the inner surface
    and transition element

    34. rigidly connected to the shaft 1. The galvanic coupling of the transducers b and 9 is carried out by means of wires passing through the rotachka in the shaft 1 (not shown) with seals preventing the outflow of an acoustically transparent medium.
    The camera 2 is covered with a small clearance screen 35, made with three OKHaivm and mounted to rotate about the axis 17, regardless of the rim 3,
    The screen 35 is mounted on bearings 36 and 37, and the supporting elements 12 and 13 are rigidly connected to the disks 4 and 5.
    The windows of the screen 35 are made with bevels 38 interacting with a spring-loaded pusher 39 designed to orient the windows of the screen: 55 parallel to the contact surface of the device with the product, for example Coarse 40. The bevels 38 of the windows of screen 35 allow a constant
    the contact of the camera 2 with the pipe 40, while the screen 35 is always somewhat does not reach the surface of the pipe.
    The supporting elements 12 and 13 support two assemblies 41 and 42; Spiral wheels 43, each of which consists of a rack 44 fixed on a shaft 45 mounted in bearings 46 and a spring 47 fixed On side surfaces of elements 12 and 13, The guide wheels 43 are made of a metal rim 48 mounted on a ball support 49 mounted on a plate 50 rigidly connected to a stand 44, the axes of rotation of the wheels 43 coincide with the axis of rotation of the chamber 2, and their diameters are somewhat smaller than the diameter of the rim 9.
    There is an option to install transducers 6 and 9 without an acoustic lens 10 with x-mount on shaft 1,
    The device works as follows.
    The device is placed on a remote-controlled carriage, which is installed inside the test pipe 40, while through the tire 11 on the rim 3, contact is made with the internal surface of the pipe, which is pressed by the spring 33.
    The guide wheels 43 touch the surface of the pipe 40, i.e. the device interacts with the pipe at three points lying in the same plane. If, when moving the device along the pipe 40, it is not strictly perpendicular to the movement path, then one of the guide wheels 43 takes a position above the second guide wheel and rotates the supporting element 12 and 13 around the axis 16, then the forming rim 3 is positioned strictly perpendicular to the movement path . In this case, the support 15 is rotated relative to the axis 16, and the rolling elements 21 relative to the elements 19 and 20.
    Due to the choice of the dispersion of the particles of an acoustically transparent medium, the signal of a certain frequency, which excites the radiating piezoelectric plate of the transducers 6 and 9, is not attenuated, while the interfering signals of other frequencies are attenuated. The surfaces of the acoustic lens 10 mate with the surfaces of the piezoplates 7 and 8 and the inner surface of the rim 3, so that the acoustically transparent medium easily fills all the gaps and allows the ultrasound signal to be inserted at a certain preferred angle.
    When the rim 3 is in contact with an obstacle, for example, a weld that can damage it, the screen 35 rests against the obstacle, turns, passes
    between the rim-3 and the tube 40, while simultaneously moving the pushers 39, which are located on the bevels 38. The rim 3 rises above the obstacle until the next window on the surface of the screen 35 is parallel to the surface of the acoustic lens 10, the pushers 39 move on bevel 38, at-retain. window screen 35 above the pipe 40,
    The use of a protective tire on the rim will significantly increase the service life of the device.
