Description

The invention relates to mechanization and automation of technological operations during non-destructive testing of industrial facilities or vehicles, for example, welds of railway tanks and their fixtures (clamps).

A scanning device for a flaw detector is known (Autosw. No. 569938), in which, to create a transverse movement of the tool (sensor), a carriage is articulated to the leading bar. The disadvantage of this device is the lack of longitudinal movement of the sensor, which does not allow to control, for example, welds along the length.

The closest technical solution to the proposed one is a device for non-destructive testing (Aut. St. SU No. 1499208), which is equipped with two magnetic wheels located on both sides of the tool (electromagnet). Each wheel has an individual electric drive. When the drives are switched on one by one, the device moves along an extended section of the controlled object.

However, the known device does not allow to overcome various obstacles, for example, the transverse rollers of the welds during the inspection of the longitudinal seam.

The aim of the invention is to improve the driving performance of the device when scanning controlled objects.

This goal is achieved in that the device is made in the form of two walking supports with magnetic bases.

In FIG. 1 shows a General view of the inventive device for scanning controlled objects; in FIG. 2 is a bottom view of the right support.

Two rod supports, left 1 and right 2, are connected by a system of double trims: upper 3 and lower 4, forming in the initial state a rectangle with articulated corners. At the bottom of each support there is a shoe in the form of a DC electromagnet 5 and 6. The upper part of the cylindrical shoe is a ring gear. Above each shoe, drives 7 and 8 are rigidly attached to the support rod, which include an electric motor 9, a worm gear 10 and a gear 11. Two traction electromagnets 12 and 13 are mounted symmetrically to each other on the lower trims. A vertical soft magnetic anchor 14 is installed on the lower trims become. The upper part of the armature is located between the poles of the traction electromagnets with the same clearance on both sides. An induction or other sensor 15, used to scan the controlled surface of the object 16, is attached to the bottom of the lower slats.

A device for scanning controlled objects works as follows. In the initial state, it is installed on the flat surface of the object 16. Two shoes 5 and 6, being electromagnets, are powered by direct current and thereby hold the entire device on the surface of the object. In this state, the first section is monitored. For the first step of the left support, the electromagnet of the left shoe 5 is turned off and the right traction electromagnet 13 is turned on, which attracts the armature 14, and the left support rises. The rectangle formed by the upper and lower trims turns into a parallelogram. At the same time, the electric motor of the right shoe 10 is turned on, and the gear wheel 11 of the right drive, being engaged with the ring gear of the right shoe, rotates the left support 1 by a predetermined angle. When the traction electromagnet and electric motor are turned off, the electromagnet of the left shoe is turned on again, and the device, having taken the first step, creates a condition for monitoring the second section of the object. For the second step, the electromagnet of the right shoe 6 is turned off and the left traction electromagnet 12 and the left electric motor are turned on. All actions of the second step are similar to the first.

Scanning of the controlled object is performed when the electromagnets of shoes, traction electromagnets and electric motors of the drives are automatically turned on to alternately raise and rotate the two supports of the proposed device. Thus, when moving it, many obstacles do not interfere with the work, the proposed device passes over them.
