Petroleum drill rod surface rust removing device

Abstract

The invention discloses a petroleum drill rod surface rust removing device which comprises an annular rotating plate. The annular rotating plate is arranged on the outer diameter of a petroleum drill rod in a sleeved mode. A gap is formed between the inner radial face of the annular rotating plate and the petroleum drill rod. A plurality of sleeves are arranged on the outer surface of the annular rotating plate. Each sleeve is just provided with one opening. The opening direction of each sleeve points to the axis of the petroleum drill rod. The petroleum drill rod surface rust removing device further comprises a sliding column penetrating through the annular rotating plate. One end of the sliding column extends into the sleeves, and the sliding column is connected to the closed end faces of the sleeves through a spiral spring. The other end of the sliding column is connected with a universal ball connected to the outer radial face of the petroleum drill rod in a pressing mode. The left side face of the annular rotating plate is provided with a support plate A provided with a first motor. A first motor output shaft of the first motor penetrates through the support plate A and points to the direction of the petroleum drill rod, one end, away from the first motor, of the first motor output shaft is connected with a grinding disk. The grinding disk is connected to the outer radial face of the petroleum drill rod in a pressing mode. The petroleum drill rod surface rust removing device can fast clear substances on the surface of the petroleum drill rod, and the hand labor intensity is relieved.

Description

technical field [0001] The invention relates to a derusting device for the surface of petroleum drill pipes. Background technique [0002] After use, the surface of the oil drill pipe will form a dirt layer and rust layer. During equipment maintenance, the oil drill pipe needs to remove the dirt layer and rust layer on the surface. The operation of the prior art is to use a manual hand-held grinder for grinding. To remove the dirt layer and rust layer, this method has the following disadvantages: the construction period is long, the construction personnel’s operation intensity is high, and the efficiency is extremely low. It takes at least 3 days to remove an oil drill pipe, and other auxiliary equipment is needed to help rotate it. The construction environment of oil drill pipe is harsh. Due to the existence of petroleum substances and rust substances on the surface of the used oil drill pipe, when grinding, the high temperature and high-speed rotation will lift the rus...
