Abstract

The invention relates to devices for non-destructive ultrasonic testing of ferromagnetic products and can be used in various fields of industry. The aim of the invention is to increase reliability in overcoming obstacles such as welds. The device contains a platform with ultrasonic transducers attached to it, propulsions in the form of magnetic wheels with motors and propulsion holders with semi-axes, which are rotatably connected to the platform on one side of the device and, on the other hand, connected to using the transverse axis with the platform. The device also contains additional magnetic wheels and ultrasonic transducers mounted on the platform. In the process of control, due to the rotation of the semi-axes, it is possible to overcome the obstacle in the form of a weld without converting the transducers from the product. 1 hp f-ly, 4 ill.

Description

The invention relates to devices for non-destructive ultrasonic testing of ferromagnetic products and can be used in various fields of research,

The purpose of the invention. increased reliability when overcoming obstacles such as welds

FIG. 1 shows a device dp moving ultrasound transducers, a general view; on (| ig. 2 - section A-A in Fig. 1; in Fig. 3 - view B in Fig. 1; in Fig. 4 - view B in Fig. 1,

The device for moving ultrasonic transducers comprises a platform 1 with ultrasonic transducers 2 attached to it, placed at the corners of platform 1 by propellers 3 in the form of magnetic wheels with motors 4, gearboxes 5 and propellers holder 6, the propulsive mechanism. 3 to the platform 1, mounted on one side of the longitudinal axis of the device bracket 7, mounted between the bracket 7 and platform 1, an elastic liner 8, the mechanism for fastening propulsion 3 to the platform 1 is made in the form of rigidly attached to the holders 6 axes 9, hinged possibility of rotation

pairs in platform 1 and in bracket 7 parallel to the longitudinal axis of the device, the transverse half-axis rigidly fixed in bracket 7 perpendicular to the semi-axes and pivotally rotatably fixed in platform 1 perpendicular to its longitudinal axis, and the additional magnetic wheels 11 are spring-loaded lenny in the middle part of the platform 1 with the possibility of tilting their axes.

In addition, the device for moving the ultrasonic transducers contains frames 12 into which additional magnetic wheels 11 are inserted and which are pivotally connected with rotation to be connected to the platform 1, the springs 13, the spring-loaded additional magnetic wheels relative to the platform 1 and the holders 14 of the ultrasonic transducers 2.

Position 15 denotes a controlled product, position 16 - weld,

The device for moving the ultrasonic transducers operates as follows.

Before starting the control, the device is mounted on the test article 15, while the propellers 3 in the form of magnetic wheels and additional magnetic wheels 11 press the ultrasonic transducers 2 and the device itself to the ferromagnetic product under test 15.

Engines 4 are put into operation, which, through gearboxes 5, transmit rotation to the propulsive devices 3, moving the device along the surface of the tested product .15. When needed. change the direction of movement of the motors 4 on one side of the device is turned off.

When an obstacle appears in the form of a weld bead 16, the wheel which is incident on it is raised due to the rotation of the semi-axis 9 fixed on the holder 6 in platform 1 or in bracket 7, as well as rotation of the transverse axis 10 in the platform 1, while the remaining magnetic wheels and additional magnetic wheels 1 1 do not tear the vehicle from the controlled product 1 5, ensuring uniform

Pressing ultrasound transducers to it 2.

When hitting the weld bead 16 of the additional magnetic wheel 11, the frame 12 rotates in a plane perpendicular to the longitudinal axis of the joint, while the spring 13 is compressed, straightening after overcoming the weld 16.

When meeting with the welded seam 16 of the ultrasonic transducer 2, it is deflected due to the rotation of the holder 14 relative to the platform 1, the smoothness of movement when overcoming the weld seam is also achieved by the presence of an elastic liner 8 installed between the platform and the bracket 7.
