Description

Technical Field

[0001] This invention relates to the field of metal pipe performance testing technology, specifically to a device for testing the surface performance of galvanized metal pipes. Background Technology

[0002] Metal pipe fittings include fittings made of various metal materials, such as steel pipes, copper pipes, and aluminum pipes. Metal pipe fittings are characterized by their light weight, corrosion resistance, high temperature resistance, and low temperature resistance. Galvanizing metal pipe fittings is done to improve their corrosion resistance and extend their service life. After galvanizing, the galvanized layer needs to be tested. The galvanized layer is scraped off with a sharp scraping tool, and then the surface condition after scraping is tested by testing equipment to detect the surface performance of the galvanized layer of the metal pipe. In the process of galvanizing metal pipes, factors such as liquid surface ripples and floating particles can cause significant differences in the thickness of the metal pipe surface. When the galvanized layer is scraped off with a scraping tool, the data at locations with different thicknesses show significant differences. Therefore, the data from a single location test can vary considerably. To address these issues, the following solutions are proposed. Summary of the Invention

The driving mechanism consists of three sets: one set is fixedly connected to the top of the lifting platform, and two sets are fixedly connected to the inner wall of the outer shell. The operating platform is equipped with testing instruments.

[0004] Preferably, the drive mechanism includes: The power unit is fixedly connected to the inner wall of the housing; The adaptation component is fixedly connected to the side wall of the power component; Before use, the lifting platform moves the power unit and the adaptation unit upwards and clamps the metal pipe.

[0005] Preferably, the limiting mechanism includes: The fixing component is fixedly connected to the side wall of the operating table; Remove the component; the component is slidably connected to the inner wall of the through hole of the fixed component. Before use, the position of the cleaning component and the scraping mechanism needs to be controlled by fixing the components.

[0006] Preferably, the removal mechanism includes: The damaged component is fixedly connected to the inner wall of the cleaning component; A limiting component is fixedly connected to the inner wall of the cleaning component; As the drive mechanism rotates and moves the metal pipe forward, the damaged component will scrape against the outer wall of the metal pipe, removing the zinc layer from the outer wall of the metal pipe.

[0007] Preferably, the power assembly includes two CNC motors fixedly connected to the inner wall of the housing, and the output ends of the two CNC motors are fixedly connected to drive rods; One of the power components and the adaptation components are fixedly connected to the top of the lifting platform. When the metal pipe enters the inner wall of the outer shell through the inlet, the lifting platform moves upward and drives the metal pipe to contact the other two sets of adaptation components through the corresponding adaptation components.

[0008] Preferably, the adaptation component includes a drive disk fixedly connected to the outer wall of the drive rod, a groove is provided on the side wall of the drive disk, and a roller is rotatably connected to the inner wall of the groove; The outer wall of the roller is fixed with a layer of rubber padding; Two sets of adaptation components fixed inside the housing will provide a lateral force for the metal pipe, while the adaptation component on top of the lifting platform will provide a rotational pressure for the metal pipe.

[0009] Preferably, the fixing component includes a fixing end fixedly connected to the side wall of the operating table, three L-plates fixedly connected to the side wall of the fixing end, and threaded rods threadedly connected to the inner wall of the L-plates. Among them, three L-plates are evenly fixed to the outer wall of the fixed end in a circumferential arrangement.

[0010] Preferably, the cleaning component includes a slide rail two fixedly connected to the inner wall of the three L-plate through holes, a mounting shell fixedly connected to the side wall of the slide rail two, and a beveled scraper fixedly connected to the side wall of the mounting shell. The end of the beveled blade is slightly upturned.

[0011] Preferably, the damaged component includes a strong spring rod fixedly connected to the side wall of the mounting shell, the other end of the strong spring rod is slidably connected to a slide rail, a track is fixedly connected to the side wall of the slide rail, a sliding blade is slidably connected to the side wall of the track, and a weak spring is fixedly connected to the top of the sliding blade. Among them, the weak spring is in the normal state, while the strong spring rod is in the compressed state.

[0012] Preferably, the limiting component includes two rolling columns rotatably connected to one side wall of the slide rail, and an inclined block is fixedly connected to the inner wall of the mounting housing; Under normal conditions, the powerful spring rod will cause the slide rail and the track to be tightly attached to the inner wall of the mounting shell, and the rolling column is located on the inclined surface of the inclined block.

[0013] The present invention has the following beneficial effects: (1) To address the problem of significant discrepancies in data from single-location detection, this invention incorporates a limiting mechanism and a scraping mechanism within the device. When the metal pipe moves towards the operating table in a rotating and translating manner, a sliding scraper, closely attached to the outer wall of the metal pipe, scrapes off a portion of the zinc layer. Figure 8 As shown, when the sliding blade is subjected to a rightward pressure, the sliding blade will bounce upward along the inner wall of the track, compressing the weak spring and causing it to deform. This allows the weak spring to accumulate potential energy, at which point a downward-sloping pit will appear on the outer wall of the metal pipe, as shown in the diagram. Figure 7 In the state of P, the weak spring then compresses the sliding scraper downwards, making contact with the outer wall of the metal pipe again. As the metal pipe rotates and moves, the sliding scraper continuously scrapes the outer wall of the metal pipe. The damaged metal pipe passes through the operating table and is continuously inspected by the testing instruments inside the operating table. Through the application of the above components, the equipment can continuously and quickly inspect the outer wall of the metal pipe at multiple locations, reducing the problem of excessively large differences in test data caused by differences in zinc layer thickness.

[0014] (2) The present invention utilizes the characteristics of the rollers that adapt to the rotation and lateral movement of the metal pipe. There is a gap between adjacent rollers. When the roller at the top of the lifting platform rotates to the highest position, the weight of the metal pipe will act on the roller position. As the drive disc rotates, the roller at the highest position rotates downward, and finally the two rollers support the metal pipe together. During this process, the height of the metal pipe will be different, and this difference will cause one end of the metal pipe to swing up and down. When the metal pipe swings, the contact position between the sliding scraper and the metal pipe will be tilted, and the wear will also be different. By applying the above components, the angle of the sliding scraper on the metal pipe can be changed, and the surface performance of the metal pipe can be detected at different angles.

[0015] (3) The present invention utilizes the above-mentioned sliding scraper to address the problem of damage to the outer wall of metal pipe fittings. A limiting component is installed inside the equipment. If the metal pipe fitting drips during the galvanizing process, "paint bumps" are likely to appear on the outer wall of the pipe fitting. When the metal pipe fitting rotates, the "paint bumps" may come into contact with the outer wall of the sliding scraper. Due to the excessive thickness of the "paint bumps", even if the sliding scraper bounces upward, it cannot cross the "paint bumps". At this time, the pressure of the rotating metal pipe fitting will act on the slide rail and the track, causing the slide rail to move towards the strong spring rod and compress the strong spring rod. During this process, the rolling column will drive the slide rail to slide upward, causing the slide rail to drive the sliding scraper to slide upward. Through the application of the above-mentioned component, the internal component will not be stuck when facing "paint bumps". (4) This invention utilizes the feature of the sliding scraper for removing zinc layers, and an inclined scraper is provided inside the equipment, wherein, for example... Figure 7 As shown, after the surface of the metal pipe is damaged, the dented position will be in state P, while some metal fragments will not detach from the outer wall of the pipe, presenting state K. At this time, the end of the beveled scraper will contact the K position and press the fragments at the K position to rotate outward along path N, preventing the K fragments from blocking the outer wall of the P position and affecting the detection instrument's detection of the P position; in addition, the end of the beveled scraper is in an upward state. When the "paint bump" reaches the J position, since the outer wall of the "paint bump" is in a smooth state, the beveled scraper will slide upward along the outer wall of the "paint bump", effectively preventing the "paint bump" from getting stuck with the end of the beveled scraper.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figure 1 - Figure 6 This invention relates to a device for testing the surface properties of galvanized metal pipe fittings, comprising a housing 13, a lifting platform 14 slidably connected to the inner wall of the housing 13, a feed inlet 15 penetratingly connected to the side wall of the housing 13, and an operating table 16 fixedly connected to the inner wall of the housing 13, and further comprising: Drive mechanism 1 is fixedly connected to the inner wall of housing 13; Restriction mechanism 2 is fixedly connected to the side wall of the operating table 16; The removal mechanism 3 is fixedly connected to the inner wall of the limiting mechanism 2; The lifting platform 14 will slide up and down along the inner wall of the outer shell 13. At the same time, the drive mechanism 1 consists of three sets, one set is fixedly connected to the top of the lifting platform 14, and two sets are fixedly connected to the inner wall of the outer shell 13. The operating table 16 is equipped with testing instruments.

[0021] Drive mechanism 1 includes: Power assembly 11 is fixedly connected to the inner wall of housing 13; Adaptive component 12 is fixedly connected to the side wall of power component 11; Before use, the lifting platform 14 will move the power assembly 11 and the adaptation assembly 12 upwards and clamp the metal pipe.

[0022] Restricted agency 2 includes: Fixing component 21 is fixedly connected to the side wall of the operating table 16; Cleaning component 22 is slidably connected to the inner wall of the through hole of fixing component 21; Before use, the position of the cleaning component 22 and the scraping mechanism 3 needs to be controlled by the fixing component 21.

[0023] The removal mechanism 3 includes: Damaged component 31 is fixedly connected to the inner wall of cleaning component 22; Limiting component 32 is fixedly connected to the inner wall of the cleaning component 22; As the drive mechanism 1 drives the metal pipe to rotate and move forward, the damaged component 31 will scrape the outer wall of the metal pipe to remove the zinc layer on the outer wall of the metal pipe.

[0024] Example 2, please refer to Figure 4 - Figure 10 The present invention is a device for testing the surface performance of galvanized metal pipe fittings. Based on Example 1, the power assembly 11 includes two CNC motors 111 fixedly connected to the inner wall of the outer shell 13, and the output ends of the two CNC motors 111 are fixedly connected to drive rods 112. Among them, three CNC motors 111 drive the corresponding drive disks 121 to rotate at the same speed, such as Figure 3 As shown, at this time, the adaptation component 12 on the top of the lifting platform 14 will provide a rotational driving force for the metal pipe, while the two sets of adaptation components 12 inside the housing 13 will provide a thrust for the metal pipe to move towards the operating table 16. This causes the metal pipe to rotate and translate in the direction of the operating table 16. During this process, the rollers 123 on the top of the lifting platform 14 are parallel to the translation direction, so that when the drive disk 121 on the top of the lifting platform 14 rotates, it does not affect the parallelism of the pipe. Similarly, the rollers 123 in the two sets of adaptation components 12 on the top are parallel to the rotation direction of the metal pipe, so that when the metal pipe is translated, it does not affect the rotation of the pipe.

[0025] The adaptation component 12 includes a drive disk 121 fixedly connected to the outer wall of the drive rod 112. A groove 122 is provided on the side wall of the drive disk 121, and a roller 123 is rotatably connected to the inner wall of the groove 122. Before use, first fix the equipment in the required position, then insert the metal fitting into the inlet 15 and push it inward, as shown. Figure 1 In this state, the lifting platform 14 then slides upward along the inner wall of the outer shell 13. The drive disk 121 and roller 123 on the top of the lifting platform 14 will contact the outer wall of the metal pipe and push the metal pipe upward, so that the outer wall of the metal pipe contacts the outer walls of the other two sets of adaptation components 12, so that the three sets of adaptation components 12 form a clamping state on the metal pipe.

[0026] The fixing component 21 includes a fixing end 211 fixedly connected to the side wall of the operating table 16, three L-plates 212 fixedly connected to the side wall of the fixing end 211, and threaded rods 213 threadedly connected to the inner wall of the L-plates 212. The rollers 123 are designed to adapt to the rotation and lateral movement of the metal pipe. There is a gap between adjacent rollers 123. When the roller 123 at the top of the lifting platform 14 rotates to its highest position, the weight of the metal pipe acts on that roller 123. As the drive disc 121 rotates, the roller 123 at its highest position rotates downwards, resulting in two rollers 123 supporting the metal pipe together. During this process, the height of the metal pipe varies, causing one end of the pipe to swing up and down. As the pipe swings, the contact point between the sliding scraper 314 and the metal pipe tilts, leading to different wear patterns. By applying these components, the angle at which the sliding scraper 314 damages the metal pipe is changed, allowing for the detection of surface performance damage at different angles.

[0027] The cleaning component 22 includes a slide rail 221 fixedly connected to the inner wall of the through hole of the three L plates 212. A mounting shell 222 is fixedly connected to the side wall of the slide rail 221, and a beveled scraper 223 is fixedly connected to the side wall of the mounting shell 222. The end of the beveled blade 223 is in an upward-curved state. When the "lacquer lump" reaches position J, since the outer wall of the "lacquer lump" is smooth, the beveled blade 223 will slide upward along the outer wall of the "lacquer lump", effectively preventing the "lacquer lump" from getting stuck with the end of the beveled blade 223.

[0028] The damaged component 31 includes a strong spring rod 311 fixedly connected to the side wall of the mounting shell 222. The other end of the strong spring rod 311 is slidably connected to a slide rail 312. A track 313 is fixedly connected to the side wall of the slide rail 312. A sliding blade 314 is slidably connected to the side wall of the track 313. A weak spring 315 is fixedly connected to the top of the sliding blade 314. To address the issue of significant discrepancies in data from single-location detections, the equipment incorporates a limiting mechanism 2 and a scraping mechanism 3. When the metal pipe moves towards the operating table 16 in a rotating and translating manner, a sliding scraper 314, closely attached to the outer wall of the metal pipe, scrapes off a portion of the zinc layer. Figure 8 As shown, when the end of the sliding blade 314 is subjected to a rightward pressure, the sliding blade 314 will bounce upward along the inner wall of the track 313 and compress the weak spring 315 to deform, causing the weak spring 315 to accumulate potential energy. At this time, a downward-concave pit will appear on the outer wall of the metal pipe, as shown in the figure. Figure 7 In the state of P, the weak spring 315 then presses the sliding scraper 314 downwards and makes contact with the outer wall of the metal pipe again. During the rotation and movement of the metal pipe itself, the sliding scraper 314 continuously scrapes the outer wall of the metal pipe. The damaged metal pipe will pass through the operating table 16 and be continuously inspected by the detection instruments inside the operating table 16. Through the application of the above components, the equipment can continuously and quickly inspect the outer wall of the metal pipe at multiple locations, reducing the problem of excessive differences in detection data caused by differences in zinc layer thickness.

[0029] The limiting component 32 includes two rolling columns 321 rotatably connected to the side wall of the slide rail 312, and an inclined block 322 is fixedly connected to the inner wall of the mounting shell 222. To address the issue of damage to the outer wall of metal pipe fittings using the aforementioned sliding scraper 314, a limiting component 32 is installed inside the equipment. If dripping occurs during the galvanizing process, "paint nodules" can easily form on the outer wall of the pipe fitting. When the pipe fitting rotates, these nodules may come into contact with the outer wall of the sliding scraper 314. Due to the excessive thickness of the nodules, even if the sliding scraper 314 bounces upwards, it cannot overcome them. At this point, the pressure from the rotating pipe fitting acts on the slide rail 312 and the track 313, causing the slide rail 312 to move towards the powerful spring rod 311 and compress it. During this process, the rolling column 321 drives the slide rail 312 to slide upwards, which in turn drives the sliding scraper 314 to slide upwards. Through the application of this component, the internal components will not become stuck when facing "paint nodules."

[0030] One specific application of this embodiment is as follows: Before use, the device is first fixed in the desired position, then the metal tube is inserted into the inlet 15 and pushed inward, presenting the following appearance. Figure 1In this state, the lifting platform 14 then slides upward along the inner wall of the outer shell 13. The drive disk 121 and roller 123 on the top of the lifting platform 14 will contact the outer wall of the metal tube and push the metal tube upward, so that the outer wall of the metal tube contacts the outer walls of the other two sets of adaptation components 12, so that the three sets of adaptation components 12 form a clamping state on the metal tube. In addition, the staff needs to manually twist the threaded rod 213 to ensure that the three sets of sliding scrapers 314 and the inclined scraper 223 can be tightly attached to the outer wall of the metal pipe. At this time, the weak spring 315 is in a slightly compressed state. Subsequently, the three CNC motors 111 drive the corresponding drive disks 121 to rotate at the same speed, such as Figure 3 As shown, at this time, the adaptation component 12 on the top of the lifting platform 14 will provide a rotational driving force for the metal pipe, while the two sets of adaptation components 12 inside the housing 13 will provide a thrust for the metal pipe to move towards the operating table 16. This causes the metal pipe to rotate and translate in the direction of the operating table 16. During this process, the rollers 123 on the top of the lifting platform 14 are parallel to the translation direction, so that when the drive disk 121 on the top of the lifting platform 14 rotates, it does not affect the parallelism of the pipe. Similarly, the rollers 123 in the two sets of adaptation components 12 on the top are parallel to the rotation direction of the metal pipe, so that when the metal pipe is translated, it does not affect the rotation of the pipe. To address the issue of significant discrepancies in data from single-location detections, the equipment incorporates a limiting mechanism 2 and a scraping mechanism 3. When the metal pipe moves towards the operating table 16 in a rotating and translating manner, a sliding scraper 314, closely attached to the outer wall of the metal pipe, scrapes off a portion of the zinc layer. Figure 8 As shown, when the end of the sliding blade 314 is subjected to a rightward pressure, the sliding blade 314 will bounce upward along the inner wall of the track 313 and compress the weak spring 315 to deform, causing the weak spring 315 to accumulate potential energy. At this time, a downward-concave pit will appear on the outer wall of the metal pipe, as shown in the figure. Figure 7 In the state of P, the weak spring 315 then presses the sliding scraper 314 downwards and makes contact with the outer wall of the metal pipe again. During the rotation and movement of the metal pipe itself, the sliding scraper 314 continuously scrapes the outer wall of the metal pipe. The damaged metal pipe will pass through the operating table 16 and be continuously inspected by the detection instruments inside the operating table 16. Through the application of the above components, the equipment can continuously and quickly inspect the outer wall of the metal pipe at multiple locations, reducing the problem of excessive differences in detection data caused by differences in zinc layer thickness.

[0031] Utilizing the characteristics of the rollers 123 that adapt to the rotation and lateral movement of the metal pipe, with a gap between adjacent rollers 123, when the roller 123 at the top of the lifting platform 14 rotates to its highest position, the weight of the metal pipe will act on that roller 123. As the drive disc 121 rotates, the roller 123 at the highest position rotates downward, ultimately resulting in two rollers 123 supporting the metal pipe together. During this process, the height of the metal pipe will differ, causing one end of the metal pipe to swing up and down. When the metal pipe swings, the contact position between the sliding scraper 314 and the metal pipe will tilt, resulting in different wear. By applying the above components, the angle at which the sliding scraper 314 damages the metal pipe can be changed, and the surface performance of the metal pipe can be detected at different angles.

[0032] To address the issue of damage to the outer wall of metal pipe fittings using the aforementioned sliding scraper 314, a limiting component 32 is installed inside the equipment. If the metal pipe fitting drips during the galvanizing process, "paint nodules" are likely to appear on the outer wall of the fitting. When the metal pipe fitting rotates, these "paint nodules" may come into contact with the outer wall of the sliding scraper 314. Due to the excessive thickness of the "paint nodules," even if the sliding scraper 314 bounces upward, it cannot cross over the "paint nodules." At this time, the pressure of the rotating metal pipe fitting will act on the slide rail 312 and the track 313, causing the slide rail 312 to move towards the strong spring rod 311 and compress the strong spring rod 311. During this process, the rolling column 321 will drive the slide rail 312 to slide upward, causing the slide rail 312 to drive the sliding scraper 314 to slide upward. Through the application of the aforementioned component, the internal components will not get stuck when facing "paint nodules." Taking advantage of the zinc-removing feature of the sliding scraper 314, an inclined scraper 223 is installed inside the equipment, wherein, for example... Figure 7 As shown, after the surface of the metal pipe is damaged, the recessed position will be in state P, while some metal fragments will not detach from the outer wall of the pipe and will be in state K. At this time, the end of the inclined scraper 223 will contact the K position and press the fragments at the K position to rotate outward along the N path to prevent the K fragments from blocking the outer wall of the P position and affecting the detection instrument's detection of the P position. In addition, the end of the beveled blade 223 is in an upward-curved state. When the "lacquer lump" reaches position J, since the outer wall of the "lacquer lump" is smooth, the beveled blade 223 will slide upward along the outer wall of the "lacquer lump", effectively preventing the "lacquer lump" from getting stuck with the end of the beveled blade 223.
