Surface derusting device for oil drill pipe

Abstract

The invention discloses a surface derusting device for petroleum drill pipes. The inner wall at the right end of the support frame is provided with two sets of symmetrically distributed sleeves, and a sliding column is inserted into the inner cavity left at the lower end of the sleeve. The top of the sliding column is connected with the bottom of the inner cavity of the sleeve through a spring, the bottom of the sliding column is provided with rollers, and the rollers are connected with the motor through a belt, and the left end surface of the support frame is provided with three sets of symmetrically distributed The right end surface of the annular plate is provided with three sets of symmetrically distributed guide columns, the guide columns are slidably connected with the guide grooves, and the inner wall of the left end of the support frame is provided with three sets of symmetrically distributed parallel hydraulic presses. The left end is provided with a telescopic rod, and the left end of the telescopic rod is connected with the annular plate. In this device for removing rust on the surface of the drill pipe, the sliding column and the sleeve are connected by a spring, so that the roller and the drill pipe are clamped more tightly, and the annular plate is connected with the hydraulic press, so that the sandpaper can repeatedly derust the drill pipe back and forth, and the rust removal is more efficient. thorough.

Description

technical field [0001] The invention relates to the technical field of rust removal for oil drill pipes, in particular to a surface rust removal device for oil drill pipes. Background technique [0002] We know that iron products will rust after a long time, and oil drill pipes will also rust after a long time. The traditional method is manual grinding. [0003] There are following disadvantages in this way to remove the dirt layer and the rust layer, the construction period is long, the operation intensity of the construction personnel is high, and the efficiency is extremely low, and the time to remove an oil drill pipe needs at least three days. It is faster to use a special descaling machine, but the traditional descaling machine fixed on the pipeline may not be firmly clamped, the grinding is not thorough, or the structure is more complicated. Contents of the invention [0004] The object of the present invention is to provide a kind of oil drill pipe surface derusti...
