Abstract
The utility model discloses an oil pipe inner coating burnishing and polishing device is designed for polishing the oil pipe inner wall coating with automizing. A transverse plate is fixed above a support of the device, a baffle is arranged at the end part of the transverse plate, the baffle is connected with a walking trolley arranged on the transverse plate through a cylinder, the other side of the walking trolley is connected with a clamp through a connecting rod, and the clamp is connected with an elastic polishing sand ball or a leather cup through a bolt. The device can polish and polish the organic coating on the inner wall of the oil pipe, thoroughly remove the unmelted particles attached to the coating, and ensure that the surface of the coating is smooth and flat, and has high automation degree and convenient operation.
Description
Technical field
The utility model relates to a kind of tubing internal coating sanding and polishing device, belongs to steel pipe internal corrosion prevention technology field.
Background technology
In Oil/gas Well is produced, tube inner wall contact corrosion medium, is easily corroded.The anti-corrosion method of tube inner wall is a lot, and one of the most frequently used method is electrostatic spraying organic coating, utilizes high-pressure electrostatic electric field to make electronegative paint particles along the contrary direction directed movement of electric field, is adsorbed in tube inner wall.In the situation that oil pipe shifts to an earlier date preheating over 180 ℃, paint particles can melt very soon, tiles, adheres to and solidify.After having solidified, on inwall, form and there is certain thickness organic coating, separate metal and Korrosionsmedium, play effect anticorrosion and that improve tubing life.
But, after electrostatic spraying completes, have part coatings particulate due to too close outer surface or be heated insufficient and molten or part is molten, be attached to coating surface, cause roughly, roughness increases.Existing treatment measures purge with blower fan conventionally, pollute the environment, and worsen workman's working condition.Some not molten particulate is solidificated in coating surface, is difficult to remove.Because oil pipe is elongated, adopt common sand paper to be difficult to carry out the whole grinding and buffing of undercoating.
Summary of the invention
The purpose of this utility model is to provide a kind of tubing internal coating sanding and polishing device, with the organic coating of automation ground sanding and polishing tube inner wall.
Concrete technology contents of the present utility model is as follows:
The support top of this device is fixed with transverse slat, and transverse slat end is provided with baffle plate, and baffle plate connects the walking dolly being located on transverse slat by cylinder, and walking dolly opposite side is by connecting rod jockey, and fixture is bolted elastic polished sand ball or leather cup.
This device can carry out sanding and polishing to the organic coating of tube inner wall, thoroughly removes the not molten particulate adhering in coating, makes coating surface smooth, and automaticity is high, easy to operate.
Accompanying drawing explanation
Fig. 1 is tubing internal coating sanding and polishing apparatus structure schematic diagram.
Fig. 2 is that tubing internal coating sanding and polishing device pushes away and sweeps tube inner wall schematic diagram.
The specific embodiment
Embodiment:
With reference to Fig. 1 and 2, embodiment of the present utility model is further illustrated:
This device mainly comprises support 1, transverse slat 2, bolt 3, fixture 4, elastic polished sand ball 5, connecting rod 6, walking dolly 7, cylinder 8 and baffle plate 9;
Tube inner wall is being coated with after organic coating, with bolt 3, elastic polished sand ball 5 is being fixed in fixture 4, then elastic polished sand ball 5 interference are being clamp-oned to the oil pipe of band coating.Cylinder 9 promotes elastic polished sand ball 5 by walking dolly 7, connecting rod 6 and fixture 4 and moves back and forth in oil pipe, relies on contact and the frictional force of sand ball and tube wall to carry out sanding and polishing to coating.
Before changing the elastic polished sand ball 5 of different model, need push away the tube inner wall of sweeping after polishing with rubber cup 10, remove the not molten particulate or the grit that fall, prevent that the new elastic polished sand ball of changing from scratching organic coating layer surface, affects the effect of grinding and buffing.After sanding and polishing completes, then push away and sweep twice with rubber cup 10, finally by oil pipe transportation device, be delivered to finished product district and put.
