Description

Technical Field

[0001] This utility model relates to the field of steel pipe welding technology, specifically to a flux scraping device for steel pipe welding. Background Technology

[0002] After the steel pipe is welded, welding slag and flux may remain in the weld area. If these residues remain on the weld for a long time, they may cause corrosion to the weld and affect its strength and durability. Therefore, it is necessary to scrape off the flux.

[0003] In existing technologies, when scraping flux off steel pipes, tools such as chisels or slag chisels are generally used to manually peel the slag off the surface of the welded part by striking it. Although this method is simple to operate, it is inefficient. Alternatively, high-pressure gas (such as compressed air, nitrogen, etc.) is used to propel ceramic abrasive particles or abrasives onto the weld, and the impact force is used to remove stubborn slag and residual flux. This method is suitable for hard-to-reach weld areas or occasions that require rapid cleaning. Therefore, a flux scraping device for steel pipe welding is proposed to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flux scraping device for steel pipe welding, comprising a base plate, a support device on the top of the base plate, a scraping mechanism and a rotating mechanism on the support device, the scraping mechanism comprising a housing, a motor being disposed inside the housing, a gear being fixedly mounted at the output shaft of the motor, a gear ring being rotatably mounted inside the housing meshing with the outer surface of the gear, three arc-shaped grooves being evenly formed on the outer surface of the gear ring, movable rods being slidably mounted inside each of the three arc-shaped grooves, and scrapers being fixedly mounted at the ends of the three movable rods away from the arc-shaped grooves.

[0005] Furthermore, the shell has an internal cavity, and a steel pipe body is installed inside the cavity. All three scrapers are in contact with the outer surface of the steel pipe body.

[0006] Furthermore, the support device includes a lifting plate, and four support rods are fixedly installed on the top of the lifting plate. Each of the four support rods has a slider fixedly installed at one end near the housing.

[0007] Furthermore, circular grooves are provided on both the left and right sides of the housing, and the four sliders are slidably connected to the circular grooves.

[0008] Furthermore, the bottom of the base plate is provided with casters, and the top of the base plate is fixedly installed with a hydraulic cylinder connected to the lifting plate.

[0009] Furthermore, the rotating mechanism includes a gear ring II, which is fixedly mounted on the outer surface of the housing. A fixing frame is fixedly mounted between the front sides of the two support rods. A motor II is fixedly mounted on the front side of the fixing frame. A gear II that meshes with the gear ring II is fixedly mounted on the output shaft of the motor II.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] 1. This flux removal device for steel pipe welding, through the setting of a scraping mechanism and a rotating mechanism, utilizes the meshing transmission of a motor-driven gear and a gear ring, as well as the sliding cooperation of an arc groove and a movable rod, to achieve uniform and tight contact between the three scrapers and the outer surface of the steel pipe body, thereby effectively scraping off the flux. This not only improves the efficiency of flux removal but also ensures the uniformity of scraping, avoiding the inefficiency and potential damage to the steel pipe caused by manual tapping. Moreover, this scraping mechanism can flexibly adapt to changes in the diameter of the steel pipe without the need to change different scraping tools, thus improving the versatility and practicality of the equipment.

[0012] 2. The flux scraping device for steel pipe welding has a support device that provides stable support for the scraping mechanism through the sliding connection between the slider and the circular groove. The rotating mechanism is driven by motor 2 to mesh with gear 2 and gear ring 2, which enables the scraping mechanism to rotate flexibly around the steel pipe body, ensuring that the flux can be completely scraped off.

[0017] 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.

[0018] Please see Figs. 1-3 This embodiment of a flux scraping device for steel pipe welding includes a base plate 1, a support device 2 on the top of the base plate 1, a scraping mechanism 3 and a rotating mechanism 4 on the support device 2, the scraping mechanism 3 includes a housing 301, a motor 302 is installed inside the housing 301, a gear 303 is fixedly installed at the output shaft of the motor 302, a gear ring 304 is rotatably installed inside the housing 301 and meshes with the outer surface of the gear 303, the outer surface of the gear ring 304 is evenly provided with three arc-shaped grooves 305, movable rods 306 are slidably installed inside the three arc-shaped grooves 305, and scraper blades 307 are fixedly installed at the ends of the three movable rods 306 away from the arc-shaped grooves 305.

[0019] By setting up the scraping mechanism 3, the housing 301 can be positioned on the outer surface of the steel pipe body 6, and the steel pipe is placed in the cavity 5 of the housing 301. Then, the scraping mechanism 3 is moved to the welding point of the steel pipe by the moving wheels at the bottom of the base plate 1. Then, by the meshing of gear 303 and gear ring 304, and the sliding connection between the arc groove 305 and the movable rod 306, when the motor 302 is started, the three movable rods 306 can drive the three scrapers 307 to contact the outer surface of the steel pipe body 6, and fix the two ends of the steel pipe body 6 by external clamps, ready to perform flux scraping operation. This scraping mechanism 3 can adapt to flux scraping operation of steel pipe bodies 6 with different diameters.

[0020] The support device 2 includes a lifting plate 201. Four support rods 202 are fixedly installed on the top of the lifting plate 201. A slider 203 is fixedly installed on one end of each of the four support rods 202 near the housing 301. Circular grooves 204 are provided on both the left and right sides of the housing 301. The four sliders 203 are slidably connected to the circular grooves 204.

[0021] By setting up the support device 2, it is easy to support the scraping mechanism 3. When the rotating mechanism 4 drives the scraping mechanism 3 to rotate, the circular grooves 204 on the left and right sides of the housing 301 slide on the outer surface of the four sliders 203, so that the scraping mechanism 3 can rotate stably.

[0022] The rotating mechanism 4 includes a gear ring 401. The gear ring 401 is fixedly installed on the outer surface of the housing 301. A fixing frame 402 is fixedly installed between the front sides of the two support rods 202. A motor 403 is fixedly installed on the front side of the fixing frame 402. A gear 404 that meshes with the gear ring 401 is fixedly installed at the output shaft of the motor 403.

[0023] By setting the rotating mechanism 4, the scraping mechanism 3 can be driven to rotate, causing the scraper 307 to rotate around the steel pipe body 6 in a circular motion, thereby scraping off the flux at the weld joint of the steel pipe body 6.

[0024] By setting up a hydraulic cylinder 7, when the hydraulic cylinder 7 is driven, it can drive the support device 2 to rise and fall, thereby driving the scraping mechanism 3 to rise and fall. The height of the scraping mechanism 3 can be flexibly adjusted according to the position of the steel pipe body 6. The working principle of the hydraulic cylinder 7 is to use the pressure of hydraulic oil to act on the piston, thereby converting hydraulic energy into mechanical energy and realizing linear reciprocating motion.

[0025] When implementing this procedure, please follow these steps:

[0026] The scraping mechanism 3 of the device is moved to the welded area on the outer surface of the steel pipe body 6 via the moving wheels at the bottom of the base plate 1, so that the steel pipe body 6 is located in the cavity 5 of the housing 301. The position of the scraper 307 in the scraping mechanism 3 is adjusted according to the diameter of the steel pipe body 6, and the height of the scraping mechanism 3 is adjusted via the hydraulic cylinder 7 to ensure that the scraper 307 contacts the outer surface of the steel pipe body 6. First, the motor 302 drives the gear 303 to rotate, which in turn drives the gear ring 304 to rotate. The gear ring 304 then drives the three arc-shaped grooves 305 to rotate, causing the three movable rods 306 to slide within the three arc-shaped grooves 305. The three scrapers 307 are moved closer to the steel pipe body 6. Before adjusting the position of the three scrapers 307, the two ends of the steel pipe body 6 are fixed by external fixing devices. Then, the motor 2 403 drives the gear 2 404 to rotate, the gear 2 404 drives the gear ring 2 401 to rotate, the gear ring 2 401 drives the housing 301 to rotate, and the housing 301 drives the three scrapers 307 to rotate to completely scrape off the flux from the steel pipe body 6. When the housing 301 rotates, the circular grooves 204 on the left and right sides slide on the outer surface of the four sliders 203 to provide stable support for the rotation of the housing 301.

[0027] In summary, this flux removal device for steel pipe welding, by setting up a scraping mechanism 3 and a rotating mechanism 4, utilizes the meshing transmission of the gear 303 and the gear ring 304 driven by the motor 302, and the sliding cooperation between the arc groove 305 and the movable rod 306, to achieve uniform and tight contact between the three scrapers 307 and the outer surface of the steel pipe body 6, thereby effectively removing the flux. This not only improves the efficiency of flux removal but also ensures the uniformity of scraping, avoiding the inefficiency and potential damage to the steel pipe caused by manual tapping. Moreover, the scraping mechanism 3 can flexibly adapt to changes in the diameter of the steel pipe without the need to change different scraping tools, thus improving the versatility and practicality of the equipment.

[0028] Furthermore, the support device 2 provides stable support for the scraping mechanism 3 through the sliding connection between the slider 203 and the circular groove 204, while the rotating mechanism 4 drives the meshing of the gear 404 and the gear ring 401 through the motor 403, realizing the flexible rotation of the scraping mechanism 3 around the steel pipe body 6, ensuring that the flux can be completely scraped off.
