Abstract

Zariadenie rieši otočné uchytenie kontro lovaného svorníka za súčasného priblíženia ultrazvukových a vírivoprúdových sond potřeb ných pre vykonanie defektoskopickej kontro ly. Podstata riešenia, ktoré tvoři zariadenie pozostávajúce z dvoch nosných dosiek, dvoch vodiacich tyčí, hnacieho lievika, príchytného kužela, z vodiacich ramien s ultrazvukovými a vírivoprúdovými sondami a zo systému napúš- ťania vazbového média spočívá v tom, že hnací lievik a príchytný kužel sú otočné, proti sebe uchytené na nosných doškách, ktoré sú zase posuvné uložené na vodiacich tyčiach. Na vodiacich tyčiach sú posuvné uchytené i dve vodiace ramená so sondami vířivých prúdov a dve ramená s dvoma sadami ultrazvukových sond. Na vodiacom ramene, slúžiacom pre sadu ultra zvukových sond, ktoré je uložené i na vodia ce j krutke, je uchytený koniec hadice začína- júcej v nádržke s vazbovým médiom a prechádza- júcej cez čerpadlo.

Riešenia najde použitie v energe- tike.The device solves the rotary attachment of the inspected bolt while simultaneously approaching the ultrasonic and eddy current probes necessary for performing the defectoscopic inspection. The essence of the solution, which creates a device consisting of two support plates, two guide rods, a driving funnel, a clamping cone, guide arms with ultrasonic and eddy current probes and a system for injecting the bonding medium, is that the driving funnel and the clamping cone are rotatable, mounted opposite each other on the support plates, which in turn are slidably mounted on the guide rods. Two guide arms with eddy current probes and two arms with two sets of ultrasonic probes are slidably mounted on the guide rods. The end of the hose starting in the tank with the binding medium and passing through the pump is attached to the guide arm, which serves for a set of ultrasonic probes, which is also mounted on the guide screw. The guide screw and the drive funnel are connected to two electric motors by a fixed gear. The solution will find application in the energy sector.

Mechanicky podobné zariadenie'vyvinuly pracovníci fy. Tiede (NSR), ktoré slúži na kontrolu svorníkov iba metodou magnetickou.Doposial sa nedeštruktívne kontroly svorníkov KP JE vykonávajú ručně a to ultrazvukovoumetodou. Nevýhoda starého spfisobu je v časovej náročnosti ručného vykonávania ultrazvukovéjkontroly a v nemožnosti vykonania ručnej kontroly metodou vířivých prúdov.No device known to us has been sent to us for double non-destructive inspection of KP NP bolts by ultrasound and eddy currents. Mechanically similar equipment was developed by the company staff. Tiede (NSR), which is used to check the bolts only by the magnetic method. So far, non-destructive inspections of the KP NP bolts are carried out manually by ultrasonic method. The disadvantage of the old method is the time-consuming performance of the ultrasound check and the impossibility of performing a manual check by the eddy current method.
