[0002] The oil pipe is one of the main oil production tools in the process of oil field development and production. After a long period of use in the well, a layer of rust will form on the inner wall. After the replaced waste oil pipe is repaired, its mechanical strength, hardness and other technical indicators can meet the process requirements and can be recycled and reused. At present, the dirt and ash on the inner wall of the oil pipe are discharged from the pipeline by motor vibration, but some of them are adhered to the pipe wall, resulting in incomplete cleaning, which has an adverse effect on subsequent work. To solve this problem, the patent document with publication number CN220348063U can clean the rust and dirt adhered to the inner wall of the oil pipe through the bristles and scrapers in the repair component. The dirt and ash generated in the cleaning process are sucked into the dust removal box through the dust suction pipe for unified collection, avoiding the problem of incomplete cleaning in the existing technology. However, since the scraper on the grinding head in the patent is rigidly connected, it is not universal for oil pipes with different inner diameters and has great limitations.

[0003] In order to solve the above problems, it is necessary to improve the grinding head based on the structure of publication number CN220348063U to solve the above technical problems. Utility Model Content

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0023] See also Figures 1 to 4 , an embodiment of the utility model provides an oil pipe cleaning and repairing device, which includes a cleaning column 1, a scraper 2, bristles 3 and an auxiliary cleaning component 4, the tail of the cleaning column 1 is fixedly installed with a connecting rod 12, and a conical column 13 is fixedly installed on the connecting rod 12, the cone head of the conical column 13 is arranged opposite to the cleaning column 1, and an annular groove 13a is provided on the conical column 13, and an elastic rubber ring 5 is sleeved on the annular groove 13a, and a mounting column 14 is fixedly installed on the tail of the conical column 13, and a plurality of annularly distributed and radially arranged threaded holes 14a are provided on the mounting column 14, the mounting column 14 is installed to the front end of the threaded rod in the patent document with publication number CN220348063U and replaces the grinding head structure in the patent, and the mounting column 14 and the threaded rod can be connected by threaded fixing or screw fixing;

[0024] The threaded fixed connection adopts welding a threaded sleeve at the tail end of the mounting column 14, setting a threaded joint at the front end of the threaded rod, and then putting the threaded sleeve onto the threaded joint for threaded fixing;

[0025] Among them, the screw fixed connection adopts welding an insert column at the tail of the installation column 14, setting a sleeve on the front end face of the threaded rod and opening a threaded hole on the side wall of the sleeve, and then inserting the insert column into the sleeve and inserting a screw into the threaded hole on the side wall of the sleeve for tightening.

[0026] In the embodiments of the present invention, please refer to Figures 1 to 4The cleaning column 1 is provided with a plurality of annularly distributed and axially arranged mounting grooves 1a, and an elastically connected scraper 2 is installed in each mounting groove 1a. Specifically, a plurality of mounting holes are provided at the bottom of the scraper 2, and a sliding rod 6 is inserted in each mounting hole. The bottom of the slide rod 6 extends out of the mounting hole and is fixedly connected to the bottom wall of the mounting groove 1a provided on the cleaning column 1. A spring 7 is sleeved on the slide rod 6, and one end of the spring 7 is fixedly connected to the lower plate surface of the scraper 2, and the other end of the spring 7 is fixedly connected to the bottom wall of the mounting groove 1a. The connecting end of each scraper 2 is fixedly installed with an oblique grip plate 21, and a card slot 21a is provided on the oblique grip plate 21. A plurality of evenly distributed bristles 3 are fixedly embedded on the outer wall of the cleaning column 1 between the two mounting grooves 1a.

[0027] It should be noted that: before the cleaning column 1 is inserted into the oil pipe, the oblique gripping plates 21 at the tail ends of the scrapers 2 are gripped, so that the scrapers 2 slide inward along the slide rod 6 and compress the spring 7. Therefore, the scrapers 2 arranged in an annular manner are retracted and slide inwardly into the mounting groove 1a for storage, so that they can be inserted into oil pipes of various inner diameters. After the cleaning column 1 is inserted into the oil pipe, the oblique gripping plates 21 are released. At this time, the scrapers 2 are driven by the elastic force of the spring 7 to slide outward along the slide rod 6 until the outer scraping end of the scraper 2 abuts against the inner wall of the oil pipe. Subsequently, the scrapers 2 and the bristles 3 on the cleaning column 1 are driven by the threaded rod to effectively clean the inner wall of the oil pipe.

[0028] It is worth noting that: when the scrapers 2 arranged in an annular manner need to be folded and slid inwardly into the mounting groove 1a for storage, the elastic rubber ring 5 is slid outwardly along the tapered column 13, so that the elastic rubber ring 5 is stretched. At this time, the oblique gripping plate 21 at the tail of each scraper 2 is gripped by hand to close it, and then the elastic rubber ring 5 is slid into the slot 21a opened in the oblique gripping plate 21, thereby completing the storage of the scraper 2 in the mounting groove 1a opened in the cleaning column 1, avoiding the hidden danger of the scraper 2 being unstable and prone to jumping when the scraper 2 is not in use.

[0029] In this solution, the column head of the cleaning column 1 is fixedly installed with a conical head 11, and a plurality of annularly distributed oblique grooves 11a are opened on the conical head 11. The oblique grooves 11a correspond to the mounting grooves 1a one by one, and the oblique grooves 11a are connected to the corresponding mounting grooves 1a. The oblique grooves 11a can discharge the cleaning liquid flowing into the mounting grooves 1a out of the mounting grooves 1a.

[0030] In the embodiments of the present invention, please refer to Figures 1 to 4 An auxiliary cleaning component 4 is installed on the cleaning column 1, and the auxiliary cleaning component 4 includes a ring 41, on which a disc-type elastic spiral strip 42 is fixedly installed, and the disc-type elastic spiral strip 42 is spirally arranged in a conical shape. The ring 41 is sleeved on the mounting column 14 and fixedly connected to the threaded hole 14a opened in the mounting column 14 through a screw 43.

[0031] It should be noted that: the ring 41 is put on the mounting post 14 and fixed with the screw 43, and when the cleaning post 1 rotates and moves into the oil pipe, the disc-type elastic spiral strip 42 on the mounting post 14 also slides into the oil pipe and rotates synchronously with the cleaning post 1. Since the disc-type elastic spiral strip 42 is spirally arranged in a conical shape, after the disc-type elastic spiral strip 42 enters the oil pipe, part of the disc-type elastic spiral strip 42 is able to perform secondary cleaning on the inner wall of the oil pipe, further improving the cleaning effect of the oil pipe.

[0032] The working principle of the oil pipe cleaning and repair equipment provided by the utility model is as follows:

[0033] Before the cleaning column 1 is inserted into the oil pipe, the oblique gripping plates 21 at the tails of the scrapers 2 are gripped so that the scrapers 2 slide inward along the slide rod 6 and compress the spring 7. As a result, the scrapers 2 arranged in an annular manner are retracted and slide inwardly into the mounting groove 1a for storage. Therefore, the scrapers 2 can be inserted into oil pipes of various inner diameters. After the cleaning column 1 is inserted into the oil pipe, the oblique gripping plates 21 are released. At this time, the scrapers 2 are driven by the elastic force of the spring 7 to slide outward along the slide rod 6 until the outer scraping end of the scraper 2 contacts the inner wall of the oil pipe. Subsequently, the cleaning column 1 is driven by the threaded rod to 1 and the bristles 3 on the oil pipe effectively clean the inner wall of the oil pipe, and the collar 41 is sleeved on the mounting post 14 and fixed with a screw 43. When the cleaning post 1 rotates into the oil pipe, the disc-type elastic spiral strip 42 on the mounting post 14 also slides into the oil pipe and rotates synchronously with the cleaning post 1. Since the disc-type elastic spiral strip 42 is spirally arranged in a conical shape, after the disc-type elastic spiral strip 42 enters the oil pipe, part of the disc-type elastic spiral strip 42 is able to perform a secondary cleaning on the inner wall of the oil pipe, further improving the cleaning effect of the oil pipe.

[0034] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0035] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
