Description

The invention relates to devices for ultrasonic testing of vertical technological channels of variable diameter from the side of the profile of the inner surface and can be used in power engineering.

The aim of the invention is to increase the reliability and quality of control by moving the ultrasonic search head in a vertical technological channel strictly vertically without breaking up around the channel axis.

Figure 1 shows a device for ultrasonic testing of vertical technological channels of products, general view; figure 2 is a view along arrow a in figure 1; in Fig.Z.- section BB in Fig.1; figure 4 is a cross section OB in figure 1; figure 5 is a cross section GT in figure 1; Fig. G is a section along the DD of Fig. 1.

A device for ultrasonic testing of vertical technological channels of products contains a search head 1, a running carriage 2 with a mechanism 3 for vertical movement of the search head mounted on it, made in the form of a winch 4 with a drum 5 with a spiral groove 6. on which a cable 7 is wound, connected to the search head 1 , an arrow 8 with a block 9 installed on it with a groove 10 for the cable 7 of the winch 4, a cable 11 connected to the search head 1, a guide roller 12 for the cable, a cable layer with a cable capacity 13, a roller 14 mounted on a trolley 2 with a profile ring groove 15 for the diameter of the cable 11. The drum 5 of the winch 4 is made with an additional profile ring groove 16 for the diameter of the cable 11, the average diameter of which is equal to the average diameter of the spiral groove 6 of the drum 5 of the winch 4, the cable layer is in in the form of an inclined rigid carrier 17, the axis of rotation 18 of which coincides with the vertical tangent 19 to the average diameter of the additional profile groove 16 of the drum 5 of the winch 4. The block 9 mounted on the boom 8 is made with a second annular groove 20 under the diameter of the cable 11, the average diameter of which is equal to the average diameter of the grooves 10 of the block 9 under the cable 7 of the winch 4.

In addition, the device for ultrasonic testing of the vertical technological channels of products contains a drive 21. The position 22 denotes a controlled product, and the position 23 indicates a controlled vertical technological channel. A device for ultrasonic testing of vertical technological channels of products operates as follows.

Before moving the trolley 2, the device is mounted on the controlled product 22 so that the ultrasonic search head 1 suspended on the boom 8 coincides with the axis of the controlled vertical technological channel 23. The vertical movement mechanism 3 of the search head 1 is turned on. To do this, turn on the drive 21 of the winch drum 5 rotation 5 4,

which feeds the cable 11 interacting with the guide roller 12 from the cable container 13 through a rigid swivel carrier 17 and simultaneously feeds the cable 7 synchronously at the same speed.

In this case, the spring-loaded pinch roller 14 presses the cable 11 to the drum 5 in the grooves 15 and 16. The cable 11 follows the head 1 through the guide roller 12 and the annular groove 20 of block 9,

it is additionally tensioned by turning the block 9 by the cable 7. In this case, the search head 1 hangs on the cable 7 located in the profile ring groove 10 of the block 9. In parallel with the cable 7, cable 11 passes and

lowers into the channel 23. Due to the fact that the cable 7 and the cable 11 are located in the same plane, the rotation of the head 1 relative to the longitudinal axis of the channel 23 is excluded. When lifting the head 1, the cable 7 will be wound on the spectral groove 6 of the drum 5, while rotating the block 9, and the cable 11, passing through the block 9 and through the inclined rigid carrier 17, will be constantly tensioned and evenly laid in the cable container 13, since

the cable layer is rotatable around axis 18, which coincides with the vertical tangent 19 of the additional annular groove 16 of the drum 5.
