Description

Technical Field

[0001] This utility model belongs to the field of pipeline operation technology, specifically a pipe opening cleaning device. Background Technology

[0002] Pipeline operations can be broadly divided into pipeline alignment, trench excavation, pipe laying, jointing, backfilling, pressure testing, flushing, disinfection, and site cleaning.

[0003] When performing interface work on pipe joints, different connection methods are used depending on different needs and materials. For example, cement pipes generally use a plug-in method, and then the plug joint is sealed. Polymer pipes generally use a heat fusion or adhesive connection method. Corrugated pipes use a socket and sealing ring sealing connection method.

[0004] When bonding polymer pipes, the smooth surface of the polymer pipes results in poor adhesion, making bonding difficult. Additionally, impurities may adhere to the pipe openings during movement. Therefore, it is necessary to clean the pipe openings. Common cleaning methods include wiping the pipe openings with a cleaning cloth and then heating them with a flame (precise heat control is required), or scraping with a knife for mechanical cleaning to expose the rough surface of the pipe openings, which facilitates subsequent bonding.

[0005] When cleaning the pipe surface with a blade, the manual control of the blade is relatively poor, resulting in inconsistent scraping depths each time. This causes the pipe opening to become out of round, affecting subsequent bonding and sealing. Therefore, it is necessary to design a blade assembly that facilitates cleaning the pipe surface, cleaning the pipe opening to a uniform depth around the opening, which is conducive to subsequent bonding. Utility Model Content

[0006] The purpose of this utility model is to provide a pipe opening cleaning device in order to solve the above-mentioned problems.

[0007] The technical solution adopted by this utility model is as follows: a pipe opening cleaning device, including a clamp, the clamp is in the shape of a ring and is divided into two semicircles, with fixing ears provided on both sides of the cut end, and a positioning component provided on the clamp.

[0009] A ring track is embedded in the center of the clamp surface, and a positioning hole is provided on one side of the clamp surface. A positioning slider is slidably provided on the clamp surface through the ring track. A cavity is provided inside the positioning slider. An anti-detachment rod is connected to the cavity through a spring. There are several positioning holes, which are evenly distributed on the clamp surface. The bottom of the anti-detachment rod fits into the positioning hole under the action of the spring.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In this utility model:

[0027] Reference Figure 1-5 A pipe opening cleaning device includes a clamp 1, which is ring-shaped and divided into two semicircles. Fixing ears 101 are provided on both sides of the cut end, and a positioning component is provided on the clamp 1.

[0028] The positioning components include: positioning hole 102, annular track 103, positioning slider 2, cavity 201, and anti-disengagement rod 202;

[0029] A ring track 103 is embedded in the center of the surface of the clamp 1. A positioning hole 102 is provided on one side of the ring track 103 on the surface of the clamp 1. A positioning slider 2 is slidably mounted on the surface of the clamp 1 via the ring track 103. A cavity 201 is provided inside the positioning slider 2. An anti-detachment rod 202 is connected to the cavity 201 by a spring. There are several positioning holes 102, which are evenly distributed on the surface of the clamp 1. The bottom of the anti-detachment rod 202 fits into the positioning hole 102 under the action of the spring. When cleaning the pipe, the anti-detachment rod 202 is pulled up and the positioning slider 2 is slidably adjusted to a suitable position. When the anti-detachment rod 202 is released, the anti-detachment rod 202 moves downward under the action of the spring, so that the bottom of the anti-detachment rod 202 is inserted into the positioning hole 102, thereby fixing the position of the positioning slider 2.

[0030] A cleaning component for cleaning the pipe opening is provided on one side of the positioning slider 2;

[0031] The surface cleaning assembly includes: support column 3, slide rail 301, cross slider 302, handle 303, adjusting block 4, threaded hole 401, insert block 5, and scraper 6;

[0032] A support column 3 is fixedly installed on one side of the positioning slider 2; a slide rail 301 is embedded inside the support column 3, and a cross slider 302 is slidably installed inside the slide rail 301. A handle 303 is fixedly installed on one side of the cross slider 302, and an adjusting block 4 is slidably installed through the cross slider 302. A threaded hole 401 is provided on one side of the adjusting block 4, and an insert block 5 is inserted into the bottom of the adjusting block 4. A scraper 6 is fixedly installed below the insert block 5. There are several threaded holes 401, which are evenly distributed on the surface of the adjusting block 4, and the cross slider... A positioning threaded hole is provided on one side of 302, and the positioning threaded hole is connected to the thread of the threaded hole 401. The adjusting block 4 is adjusted to a suitable position by moving the adjusting block 4 up and down, so that the positioning threaded hole 401 and the positioning threaded hole on the surface of the cross slider 302 correspond. The adjusting block 4 and the cross slider 302 are then fixed by bolts. The angle between the scraper 6 and the horizontal plane is 30 degrees. The scraper 6 is semi-circular in shape. The 30-degree angle makes it easier for the scraper 6 to clean the pipe opening. The semi-circular scraper can also better fit the shape of the pipe opening.

[0033] Working principle: First, clamp 1 is placed at the pipe opening. The fixing ears 101 on both sides of clamp 1 are tightened with bolts, fixing clamp 1 at the pipe opening. Clamp 1 and the pipe form a concentric circle. Then, the adjusting block 4 is adjusted up and down to a suitable position so that the scraper 6 is aligned with the pipe opening. The scraper 6 has a cutting depth of 0.2mm. The threaded hole 401 and the positioning threaded hole on the surface of the cross slider 302 are aligned, and the adjusting block 4 and the cross slider 302 are fixed with bolts. Next, the handle 303 is pulled, causing the cross slider 302 to move horizontally back and forth along the slide rail 301, causing the scraper 6 to scrape and clean the surface of the pipe opening, achieving the purpose of surface cleaning, removing oil and impurities from the pipe opening and exposing the rough surface. The angle between the scraper 6 and the horizontal plane is 30 degrees, and the scraper 6 is semi-circular in shape. The 30-degree angle makes it easier for the scraper 6 to clean the pipe opening, and the semi-circular scraper can better fit the shape of the pipe opening. Finally, by moving the positioning slider 2 to the position of the clamp 1, the anti-detachment rod 202 is pulled up. By sliding the positioning slider 2 to the next position, when the anti-detachment rod 202 is released, the anti-detachment rod 202 moves downward under the action of the spring, so that the bottom of the anti-detachment rod 202 is inserted into the positioning hole 102, thereby fixing the position of the positioning slider 2. Then, the scraper 6 is used to scrape and clean this position. The circular motion of the positioning slider 2, in conjunction with the scraper 6, cleans the surface of the pipe opening, thereby achieving the purpose of cleaning the entire surface of the pipe opening. This setting ensures that the scraper 6 cleans the pipe opening surface with a consistent thickness, improving the cleaning accuracy.
