Beschreibung
Zusammenfassung:	The invention discLoses an automatic advancing drift diameter gauge. The drift diameter gauge comprises a drift diameter gauge body, a power system, a transmission system and a supporting system, beLongs to the technicaL fieLd of oiL driLLing weLL compLetion engineering operation, and is suitabLe for detecting drift diameter dimensions of driLLing rods, sLeeve tubes and oiL pipes. The drift diameter gauge is characterized in that the power system can automaticaLLy provide sufficient power for the advancing of the drift diameter gauge, efficient and stabLe transmission can be provided by the transmission system by meshing worm wheeLs and worm rods with a gear group, and automatic centering and baLanced advancing of the drift diameter gauge can be ensured by the supporting system. By means of the drift diameter gauge, the detection of the drift diameter of a coLumn can be compLeted by one person on the ground, the use is safe, reLiabLe and simpLe and convenient, the working efficiency can be improved, safety ri
