Surface rust removal device for petroleum drill rod

Abstract

The invention discloses a surface rust removal device for a petroleum drill rod. Automatic flow-type grinding rust removal for the petroleum drill rod can be achieved, moreover the rust removal effectis good, rapid and thorough rust removal for the petroleum drill rod can be achieved, during rust removal, while a high-speed grinding motor of a grinding rust-removal mechanism rotates at high speed, a swinging driving mechanism drives a swinging seat to swing, then while grinding steel wire bundles swing, a telescopic driving mechanism further drives the grinding steel wire bundles to reciprocate up and down slightly, rapid rust-removal treatment for the drill rod at all angles and in all areas can be guaranteed, and the thorough rust removal is guaranteed. During rust removal, the petroleum drill rod can rotate around the axial direction of the device, and thus, turnover rust removal can be achieved while conveying can be achieved automatically; and during rust removal, the petroleum drill rod can be jacked up and pressed with a pressing beam and a pressing wheel set, driving of a pressing rod driving mechanism is flexible, shifting of pressing down and lifting up of the pressing wheel set can be conveniently achieved, and the operation conveniences are improved.

Description

Technical field [0001] The invention specifically relates to the technical field of rust removal of drill pipes, in particular to a device for removing rust on the surface of oil drill pipes. Background technique [0002] For oil drill pipes, because it produces a lot of slurry when drilling oil extraction holes, this leads to more rust after each use for a period of time, which not only damages the drill pipes And in the next use, these corrosion will greatly reduce the efficiency and reliability of drilling. Therefore, for the drill pipe, it needs to be derusted regularly to facilitate maintenance such as oiling the surface of the drill pipe. The current rust removal generally uses a hand-held rust remover to remove rust. This method not only has low rust removal efficiency, but also has a high labor intensity for rust removal, which affects the cost of rust removal. In addition, when removing rust, due to oil drill pipe It is generally very heavy, which makes it difficult to ...

Problems solved by technology

[0002] For oil drill pipes, a lot of slurry will be produced when drilling oil drilling holes, which will cause more corrosion of oil drill pipes after each use for a period of time, which will not only cause damage to the drill pipes , and in the next use, these rusts will greatly reduce the efficiency and reliability of drilling. Therefore, for drill pipes, it is necessary to regularly derust them, so that the surface of the drill pipe can be oiled and other maintenance

The current rust removal is generally carried out by using a hand-held rust remover. This method not only has low rust removal efficiency, but also has a high labor intensity for rust removal, which affects the cost of rust removal. In addition, during rust removal, due to oil drill pipe It is generally very heavy, which makes it difficult to turn and feed it during derusting, which reduces the uniformity of derusting and makes it difficult to ensure the thoroughness of derusting
