Abstract

The invention discloses an automatic cleaner for cleaning oil stains on the external thread surface of a petroleum drilling tool joint. The automatic cleaner comprises a power device and a steel wire brush; the power device comprises a housing as well as a motor and a speed reducer which are fixed in the housing; the steel wire brush comprises a hollow connecting sleeve, a cross connecting frame, a stabilizing bar, a brush head and a clamping plate; one end of the hollow connecting sleeve is connected with an output shaft of the speed reducer by screw thread, the cross connecting frame is sheathed in the thin end of the stabilizing bar, the other end of the hollow connecting sleeve is connected with the stabilizing bar by screw thread, and the cross connecting frame is clamped between the thick end of the stabilizing bar and the hollow connecting sleeve; the brush head consists of a brush plate and steel wires; the clamping plate consists of a brush head clamping part and a connecting part, a brush plate of the brush head is connected with a clamping part of the brush head by a slot, and the four connecting arms of the cross connecting frame are correspondingly connected with the connecting parts of the four clamping plates by bolts and nuts. The automatic cleaner for cleaning oil stains on the external thread surface of the petroleum drilling tool joint in the invention has the advantages of convenience in carrying and operation, saving manpower and thorough cleaning.

Description

technical field [0001] The invention relates to an automatic cleaner for oil stains on the external thread surface of a petroleum drilling tool joint. Background technique [0002] At present, the tool used to clean oil stains on the surface of the external thread of the oil drilling tool joint at the drilling site is a wire brush. The structure of the wire brush is to fixedly connect several steel wires of equal length on a plate-shaped brush plate. When in use, first apply an appropriate amount of sand or oil on the surface of the external thread of the drill tool joint; then use a hand-held wire brush to manually remove the oil and dirt attached to the surface of the external thread of the joint; finally use a high-pressure air pipe to blow away the dirt to complete the cleaning . Using a wire brush to manually clean the oil on the surface of the external thread of the oil drilling tool joint is labor-intensive, time-consuming and laborious, and the cleaning efficiency i...
