Description

Technical Field

[0001] This utility model relates to the field of oil pipe processing technology, and in particular to an oil pipe anti-wax coating processing device. Background Technology

[0002] In thin oil flowing wells, produced fluid flows from the oil layer to the surface pipeline along the inner bore of the tubing under the pressure of the oil layer. During this process, corrosive compounds in the produced fluid can corrode the tubing. The scouring effect of the fluid flow exacerbates tubing wear, significantly shortening its service life. Therefore, during tubing manufacturing, an anti-corrosion coating is sprayed onto the inner wall to prevent damage to the paraffin coating. This process involves multiple steps, such as threading, high-temperature sintering, rust removal, electroplating, heat treatment, and spraying. Because tubing diameters vary widely, typically measured in millimeters (mm), with common diameters including 4mm, 6mm, and 8mm, the nozzle size of the spraying device remains largely unchanged during spraying. This makes it difficult to align the nozzle axis with the axis of some sections of the tubing, resulting in poor coating of the tubing's interior. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the existing technology that, during the spraying process of oil pipes of different diameters, the axis of the spray nozzle of the spraying device is difficult to coincide with the axis of some oil pipes, resulting in poor spraying effect inside the oil pipes after the spraying device has sprayed them. Therefore, an oil pipe anti-wax coating processing device is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for processing anti-wax coating on oil pipes is designed, including a base, a fixing ring on the outer side of the base, and several telescopic components on the outer side of the fixing ring. The telescopic components are arranged in a circumferential shape around the fixing ring, and rollers are provided on the extension rods of the telescopic components. A groove is opened on one side of the base, and a nozzle assembly is connected to the groove through a sealed bearing. A connecting groove is provided in the groove. A drive assembly is provided on the other side of the base, and the drive assembly causes the nozzle assembly to rotate on the base.

[0006] Preferably, a connecting pipe is provided at one end of the connecting groove.

[0007] Preferably, the drive assembly includes a placement slot formed on the base, a servo motor is disposed in the placement slot, the output shaft of the servo motor passes through the placement slot through a sealed bearing and extends into the groove, and one end of the nozzle assembly is provided with a plurality of connecting rods, one end of each of the plurality of connecting rods extending into the output shaft of the servo motor and having a retaining groove.

[0008] Preferably, there is a gap between the servo motor and the connecting slot.

[0009] Preferably, all of the rollers are made of rubber material.

[0010] The present invention provides an oil pipe anti-wax coating processing device, which has the following advantages: the oil pipe anti-wax coating processing device adjusts several telescopic components and rollers so that the axis of the base carrying the nozzle assembly coincides with the axis of oil pipes of different diameters, so that the nozzle assembly sprays the inside of oil pipes of different diameters more evenly, thereby improving the spraying effect inside oil pipes of different diameters.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1: Refer to Figure 1-4An oil pipe anti-wax coating processing device includes a base 1, a fixing ring 2 fixedly installed on the outside of the base 1, and a plurality of telescopic components 3 arranged circumferentially around the fixing ring 2. Rollers 4 are provided on the extension rods of the telescopic components 3. A groove 5 is provided on one side of the base 1, and a nozzle assembly 6 is connected to the groove 5 through a sealed bearing. A connecting groove 7 is provided in the groove 5. A drive assembly is provided on the other side of the base 1. The drive assembly includes a placement groove 9 opened on the base 1. A servo motor 10 is provided in the placement groove 9. The output shaft of the servo motor 10 passes through the placement groove 9 through the sealed bearing and extends into the groove 5. A plurality of connecting rods 11 are provided at one end of the nozzle assembly 6. One end of each connecting rod 11 extends into the output shaft of the servo motor 10 and leaves a slot 12. The drive assembly causes the nozzle assembly 6 to rotate on the base 1.

[0018] Combined with appendix Figure 1-4 A push rod 13 is provided on one side of the base 1, which reduces the difficulty of moving the device inside the oil pipe, making it easier for operators to operate the device. After connecting the external spraying material pipeline to the connecting groove 7, before spraying the inner wall of the oil pipe through the nozzle assembly 6, the base 1 is pushed into the oil pipe. The external control switch adjusts several telescopic components 3 and rollers 4 so that the axis of the base 1 with the nozzle assembly 6 coincides with the axis of the oil pipe, making the nozzle assembly 6 spray the inside of the oil pipe evenly. Moreover, the output shaft of the servo motor 10 rotates the nozzle assembly 6 through several connecting rods 11, making the nozzle assembly 6 spray the inner wall of the oil pipe even more evenly, thereby improving the spraying effect inside the oil pipe. This allows the device to spray the inside of oil pipes of different diameters well, thereby reducing the number of nozzle assemblies used in the spraying device and reducing the cost of using the device.

[0019] Example 2: An optimization based on Example 1, with reference to... Figure 1-4 One end of the connecting groove 7 is provided with a connecting pipe 8, there is a gap between the servo motor 10 and the connecting groove 7, and several rollers 4 are all made of rubber material.

[0020] By setting up a connecting pipe 8, after the external device's pipe is connected to the connecting pipe 8, the external device's spraying material enters the connecting groove 7 through the connecting pipe 8. The connecting groove 7 sends the spraying material into the groove 5, making it more convenient to spray the inner wall of the oil pipe through the nozzle assembly 6. Moreover, the outer shell of the servo motor 10 is less likely to come into contact with the spraying material, making the servo motor 10 less likely to be contaminated.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
