[0009] In an optional embodiment, when the first telescopic component drives the connection between the first arm and the second arm to protrude upward, the end of the second arm away from the second support protrudes relative to the first arm to prevent the steel pipe supported by the tumbling device from rolling toward the first support.

[0010] In an optional embodiment, the first telescopic component is driven to engage with the connection between the first arm and the second arm.

[0011] In an optional embodiment, when the first telescopic component is in the first extended state, the connection between the first arm and the second arm protrudes upward; when the first telescopic component is in the retracted state, the connection between the first arm and the second arm is recessed downward.

[0012] Secondly, this utility model provides a steel pipe anti-corrosion production equipment, including a steel pipe storage rack according to any of the aforementioned embodiments.

[0013] In an optional embodiment, the steel pipe anti-corrosion production equipment further includes a first roller assembly, which is disposed between the first support and the second support. When the first telescopic assembly causes the connection between the first arm and the second arm to recess downwards, the steel pipe in the first receiving groove is supported by the first roller assembly.

[0014] In an optional embodiment, the steel pipe anti-corrosion production equipment further includes a second roller assembly, a third support arm, a second telescopic assembly, and auxiliary rollers; The third arm has a second receiving groove for accommodating the steel pipe, and one end of the third arm is rotatably connected to the end of the first support away from the first arm; The second telescopic component is driven by the third support arm to switch between the first and second positions. When the third support arm is in the first position, the steel pipe in the second receiving groove is supported by the second roller assembly and can be driven to rotate around its own rotation axis under the action of the second roller assembly. When the third support arm is in the second position, the third support arm can lift the steel pipe away from the second roller assembly and the steel pipe can roll along the third support arm to the first bracket. An auxiliary roller is rotatably mounted on the third arm to support the steel pipe located in the second receiving groove.

[0015] In an optional embodiment, the third arm includes a first arm and a second arm connected at an angle, with the end of the second arm away from the first arm rotatably connected to the first support; at least one of the first arm and the second arm is rotatably connected to an auxiliary roller; and / or, When the third arm is in the first position, the end of the second arm away from the first arm protrudes relative to the first support to prevent the steel pipe supported by the first support from rolling back into the second receiving groove.

[0016] Thirdly, this utility model provides a steel pipe anti-corrosion production equipment, including: a first support, a second roller assembly, a third support arm, a second telescopic assembly, and auxiliary rollers; The third arm has a second receiving groove for accommodating the steel pipe, and one end of the third arm is rotatably connected to the first support. The second telescopic component is driven by the third support arm to switch between the first and second positions. When the third support arm is in the first position, the steel pipe in the second receiving groove is supported by the second roller assembly and can be driven to rotate around its own rotation axis under the action of the second roller assembly. When the third support arm is in the second position, the third support arm can lift the steel pipe away from the second roller assembly and the steel pipe can roll along the third support arm to the first bracket. An auxiliary roller is rotatably mounted on the third arm to support the steel pipe located in the second receiving groove.

[0017] The beneficial effects of the steel pipe storage rack provided in this embodiment of the present invention include: the tumbling device between the first support and the second support of the steel pipe storage rack provided in this embodiment of the present invention includes a first arm, a second arm, and a first telescopic component. By using the first telescopic component to make the connection between the first arm and the second arm protrude upward or recede downward, the first arm and the second arm with the connection recessed downward can receive the steel pipe that rolls to the tumbling device, or the first arm and the second arm with the connection protruding upward can make the steel pipe located at the tumbling device roll onto the second support. With this configuration, only one telescopic component is needed to realize the receiving and output of steel pipes by the tumbling device, reducing the number of telescopic components, simplifying the structure of the tumbling device, and helping to reduce costs.

[0018] The steel pipe anti-corrosion production equipment provided in this embodiment of the utility model has all the beneficial effects of the steel pipe storage rack, such as: simplifying the structure of the tumbling device and reducing equipment costs.

[0019] The beneficial effects of the steel pipe anti-corrosion production equipment provided in this embodiment of the utility model also include: since the auxiliary roller is rotatably connected to the third arm, when the second telescopic component drives the third arm to switch to the second position so as to use the third arm to lift the steel pipe away from the second roller assembly, the steel pipe can still be supported by the auxiliary roller, so that under the action of the auxiliary roller, it can maintain the inertia of rotating around its own rotation axis and continue to rotate, instead of immediately stopping the rotation and causing the steel pipe surface to be scratched by the third arm due to the "sudden braking"; afterward, when the steel pipe rolls and separates from the auxiliary roller, the inertia of the steel pipe gradually decreases under the action of gravity, and there will be no sudden stop downward, so that the steel pipe surface will not be scratched by the third arm.

[0026] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0028] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0029] Please refer to Figure 1 The steel pipe anti-corrosion production equipment 010 provided by the related technology includes an anti-corrosion station 510, a first support 100, a grinding station 520, and a second support 200. Both the anti-corrosion station 510 and the grinding station 520 are equipped with roller assemblies, each including a driving wheel 341 and a driven wheel 342. The driving wheel 341 and the driven wheel 342 jointly support the steel pipe 600, and when the driving wheel 341 rotates, it can drive the steel pipe 600 and the driven wheel 342 to rotate simultaneously. Both the anti-corrosion station 510 and the grinding station 520 are also equipped with a tumbling device 300, used to tumble the steel pipe 600 located at the anti-corrosion station 510 towards the grinding station 520, or to tumble the steel pipe 600 located at the grinding station 520 towards the anti-corrosion station 510 or the next station.

[0030] The tumbling device 300 provided by the related technology includes a first hydraulic cylinder 521, a second hydraulic cylinder 522, a first arm 310 and a second arm 320, both of which are V-shaped. One end of the first arm 310 is rotatably connected to the first support 100 and is also connected to the first hydraulic cylinder 521. One end of the second arm 320 is rotatably connected to the second support 200 and is also connected to the second hydraulic cylinder 522.

[0031] The process of using the rolling device 300 to deliver the steel pipe 600 from the first support 100 to the second support 200 includes: 1. Extending the first hydraulic cylinder 521 and retracting the second hydraulic cylinder 522, so that the first hydraulic cylinder 521 switches the straight arm of the first support 310 near the first support 100 to a roughly horizontal state, so that the steel pipe 600 can roll from the first support 100 onto the straight arm of the first support 310 near the first support 100 (the straight arm of the first support 310 away from the first support 100 can block the steel pipe 600). 1. Continue rolling); 2. Retract the first hydraulic cylinder 521, so that the first arm 310 carrying the steel pipe 600 descends to the roller assembly of the grinding station 520; 3. Extend the second hydraulic cylinder 522 to drive the second arm 320 to rise up near the straight arm of the second support 200 to a certain angle relative to the second support 200, so that the steel pipe 600 is lifted from the roller assembly of the grinding station 520 and rolled along the straight arm of the second arm 320 near the second support 200 onto the second support 200.

[0032] The inventors discovered that the tumbling device 300 provided by the related technology requires a large number of hydraulic cylinders, has a complex structure, and is costly.

[0033] To address the aforementioned problems, this embodiment provides a steel pipe corrosion protection production equipment with a novel steel pipe storage rack; this steel pipe storage rack includes a simple tilting device. A detailed description will follow with reference to the accompanying drawings.

[0034] Please refer to Figure 2 and Figure 3 The steel pipe anti-corrosion production equipment 010 of this embodiment includes a steel pipe storage rack, which includes a first support 100, a second support 200, and a tumbling device 300. The first support 100 and the second support 200 are spaced apart, and the tumbling device 300 is disposed between the first support 100 and the second support 200. Both the first support 100 and the second support 200 are used to temporarily store steel pipes 600. The tumbling device 300 includes a first support arm 310, a second support arm 320, and a first telescopic component 330. The two ends of the first support arm 310 are rotatably connected to the first support 100 and the second support arm 320, respectively. The second support arm 320 is located away from the first support arm 100. One end of the support arm 310 is movably disposed on the second bracket 200; the first telescopic component 330 is in transmission engagement with at least one of the first support arm 310 and the second support arm 320; the first telescopic component 330 is used to make the connection between the first support arm 310 and the second support arm 320 protrude upward so that the steel pipe 600 supported by the first support arm 310 and the second support arm 320 can roll onto the second bracket 200, or the first telescopic component 330 is used to make the connection between the first support arm 310 and the second support arm 320 recessed downward, and the first support arm 310 and the second support arm 320 together form a first receiving groove 301 for accommodating the steel pipe 600.

[0035] By using the first telescopic component 330 to make the connection between the first arm 310 and the second arm 320 protrude upwards or recess downwards, the steel pipe 600 rolling to the tumbling device 300 can be received by the first arm 310 and the second arm 320 with the connection recessed downwards, or the steel pipe 600 located at the tumbling device 300 can be rolled onto the second support 200 by the first arm 310 and the second arm 320 with the connection protruding upwards. With this configuration, the tumbling device 300 can receive and output the steel pipe 600 using only one telescopic component, reducing the number of telescopic components, simplifying the structure of the tumbling device 300, and helping to reduce costs.

[0036] Optionally, the first telescopic assembly 330 may include, but is not limited to, a hydraulic cylinder and an electric push rod.

[0037] Please refer to Figure 4Optionally, the first support 100 has a first storage surface 110, and the second support 200 has a second storage surface 210. Both the first storage surface 110 and the second storage surface 210 are used to temporarily store the steel pipe 600. The first telescopic component 330 is also used to move the connection between the first support arm 310 and the second support arm 320 to an intermediate position. When the connection between the first support arm 310 and the second support arm 320 is in the intermediate position, the first support arm 310 and the second support arm 320 together form a transition surface 302, and the transition surface 302 and the first storage surface 110 and the second storage surface 210 are located on the same horizontal plane.

[0038] This configuration allows the steel pipe 600 to roll freely between the first storage surface 110, the transition surface 302, and the second storage surface 210 when the connection between the first telescopic component 330 and the first support arm 310 and the second support arm 320 is in the middle position, ensuring that the steel pipe 600 can move more flexibly between the first support 100 and the second support 200.

[0039] Of course, in other embodiments, the first storage surface and the second storage surface 210 are not on the same horizontal plane. When the connection between the first support arm 310 and the second support arm 320 is in the middle position, the transition surface 302 formed by the first support arm 310 and the second support arm 320 is on the same horizontal plane as either the first storage surface 110 or the second storage surface 210.

[0040] It should be noted that, please refer to Figure 2 , Figure 3 and Figure 4 When the first telescopic component 330 causes the connection between the first arm 310 and the second arm 320 to protrude upwards, the first arm 310 and the second arm 320 generally form an inverted "V" shape, and the connection between them is located above the transition surface 302 formed by the two arms. When the first telescopic component 330 causes the connection between the first arm 310 and the second arm 320 to recess downwards, the first arm 310 and the second arm 320 generally form a "V" shape, and the connection between them is located below the transition surface 302 formed by the two arms.

[0041] It should also be noted that, please refer to Figure 5 If it is only necessary to use the tumbling device 300 to temporarily store the steel pipe 600, the first telescopic component 330 can be used to position the connection between the first arm 310 and the second arm 320 between the middle position and the downward recessed position, so that a certain recess is formed between the first arm 310 and the second arm 320 to temporarily store the steel pipe 600, while also preventing the steel pipe 600 from contacting the first roller assembly 340.

[0042] Alternatively, please refer to Figure 2 , Figure 3 and Figure 4 The second arm 320, at its end furthest from the first arm 310, is connected to a roller 321. The second support 200 is provided with a roller base 322, and the roller 321 slides in cooperation with the roller base 322. When the first telescopic component 330 drives the connection between the first arm 310 and the second arm 320 to bulge upwards or recess downwards, the roller 321 slides relative to the roller base 322. This sliding cooperation between the roller 321 and the roller base 322 improves the flexibility of the connection between the second arm 320 and the first arm 310, allowing it to bulge upwards, recess downwards, or switch to an intermediate position. It also ensures that when the connection between the first arm 310 and the second arm 320 bulges upwards, the second arm 320 can smoothly and reliably guide the supported steel pipe 600 onto the second support 200.

[0043] Optionally, the roller base 322 is provided with a guide groove (not shown in the figure), and the roller 321 is rotatably embedded in the guide groove. That is, when the first telescopic component 330 switches the connection between the first arm 310 and the second arm 320 between an upwardly protruding position and a downwardly recessed position, the roller 321 can roll within the guide groove. Positioning the roller 321 within the guide groove ensures a stable fit between the roller 321 and the roller base 322.

[0044] Specifically, when the first telescopic component 330 switches the connection between the first arm 310 and the second arm 320 from a downwardly recessed position to an upwardly protruding position, or from an upwardly protruding position to a downwardly recessed position, the roller 321 can first roll away from the first support 100 in the guide groove, and then roll towards the first support 100; when the first telescopic component 330 moves the connection between the first arm 310 and the second arm 320 from an upwardly protruding position or a downwardly recessed position towards the middle position, the roller 321 can roll away from the first support 100 in the guide groove.

[0045] Optionally, the roller 321 is rotatably connected to the second arm 320 via a support shaft, wherein the roller 321 is fixedly connected to the support shaft, and the support shaft is rotatably connected to the second arm 320.

[0046] Alternatively, in other embodiments, the roller 321 is rotatably connected to the support shaft, which is fixedly connected to the second arm 320.

[0047] Alternatively, please refer to Figure 2 , Figure 3 and Figure 4When the first telescopic component 330 drives the connection between the first support arm 310 and the second support arm 320 to protrude upward, the end of the second support arm 320 away from the second bracket 200 protrudes relative to the first support arm 310 to prevent the steel pipe 600 supported by the tumbling device 300 from rolling toward the first bracket 100. Specifically, the end of the first arm 310 furthest from the first support 100 is rotatably connected to the second arm 320 via a pivot. The end of the second arm 320 furthest from the second support 200 extends beyond the first arm 310. When the connection between the first arm 310 and the second arm 320 is in the middle position, the end of the second arm 320 furthest from the second support 200 coincides with the first arm 310. When the connection between the first arm 310 and the second arm 320 protrudes upwards, the end of the second arm 320 furthest from the second support 200 (i.e., the portion of the second arm 320 that extends beyond the first arm 310) protrudes beyond the first arm 310 to prevent the steel pipe 600 supported by the tumbling device 300 from rolling toward the first support 100. This arrangement ensures the reliability of the tumbling device 300 in rolling the steel pipe 600 toward the second support 200.

[0048] Optionally, the first telescopic component 330 is driven to engage with the connection between the first arm 310 and the second arm 320. For example, the first telescopic component 330 can be driven to engage with the pivot shaft connecting the first arm 310 and the second arm 320 (i.e., the first telescopic component 330 is driven and rotatably connected to the pivot shaft connecting the first arm 310 and the second arm 320). This configuration allows the first telescopic component 330 to more smoothly drive the connection between the first arm 310 and the second arm 320 to switch between an upwardly protruding and a downwardly recessed position.

[0049] Of course, in other embodiments, the first telescopic component 330 may be connected to the first arm 310 or the second arm 320 only in a transmission connection.

[0050] Optionally, when the first telescopic component 330 is in the first extended state, the connection between the first arm 310 and the second arm 320 protrudes upward; when the first telescopic component 330 is in the retracted state, the connection between the first arm 310 and the second arm 320 is recessed downward; when the first telescopic component 330 is in the second extended state, the connection between the first arm 310 and the second arm 320 is located in the middle position; wherein, the extension length of the first telescopic component 330 in the first extended state is greater than the extension length in the second extended state. This arrangement allows the first telescopic component 330 to be positioned below the first arm 310 and the second arm 320, facilitating a compact structural design.

[0051] Please refer to Figure 2The steel pipe anti-corrosion production equipment 010 in this embodiment also includes a first roller assembly 340, which is disposed between the first support 100 and the second support 200. When the first telescopic component 330 causes the connection between the first support arm 310 and the second support arm 320 to be recessed downward, the steel pipe 600 in the first receiving groove 301 is supported by the first roller assembly 340 and can rotate under the drive of the first roller assembly 340.

[0052] Optionally, the steel pipe anti-corrosion production equipment 010 also includes a grinding device (not shown in the figure), which is disposed between the first support 100 and the second support 200. When the first telescopic component 330 causes the connection between the first support arm 310 and the second support arm 320 to be recessed downward, so that the steel pipe 600 in the first receiving groove 301 is supported by the first roller assembly 340, the grinding device can also be used to grind the steel pipe 600 (for example, to grind the axial end of the steel pipe 600).

[0053] Since the first telescopic component 330 can also position the connection between the first arm 310 and the second arm 320 in the middle position, when the steel pipe 600 does not need to be ground, the first arm 310 and the second arm 320, whose connection is in the middle position, can be used to directly guide the steel pipe 600 from the first support 100 to the second support 200, which effectively improves the efficiency of the steel pipe 600 transfer.

[0054] It should be noted that the structure and working principle of the first roller assembly 340 are similar to those of related technologies. For example, the first roller assembly 340 includes a driving wheel 341 and a driven wheel 342 that are spaced apart. The driving wheel 341 and the driven wheel 342 are used together to support the steel pipe 600. The driving wheel 341 is driven by a motor, and the driven wheel 342 is rotatably mounted on the base. When the motor drives the driving wheel 341 to rotate, the driving wheel 341 can drive the steel pipe 600 and the driven wheel 342 to rotate.

[0055] The inventors further investigated and found that, please refer to... Figure 1 and Figure 6 The steel pipe anti-corrosion production equipment 010 provided by the related technology is prone to damaging the anti-corrosion layer on the surface of the steel pipe 600 when delivering the steel pipe 600 with the anti-corrosion layer attached to its surface from the anti-corrosion station 510 to the first support 100, thereby reducing the anti-corrosion quality of the steel pipe 600.

[0056] Specifically, the steel pipe anti-corrosion production equipment 010 provided by the related technology has an anti-corrosion station 510 located upstream of the first support 100. The anti-corrosion station 510 includes a second roller assembly 400, a third support arm 410, and a second telescopic assembly 420. The third support arm 410 has a second receiving groove 413 for accommodating the steel pipe 600. One end of the third support arm 410 is rotatably connected to the end of the first support 100 away from the first support arm 310. The second telescopic assembly 420 is in a transmission cooperation with the third support arm 410 to drive the third support arm 410 in a first position and Switching between the second and third positions; when the third arm 410 is in the first position, the steel pipe 600 in the second receiving groove 413 is supported by the second roller assembly 400, and the second roller assembly 400 can drive the steel pipe 600 to rotate around its own rotation axis, so as to prepare an anti-corrosion layer on the surface of the rotating steel pipe 600; when the third arm 410 is in the second position, the third arm 410 can lift the steel pipe 600 away from the second roller assembly 400 and make the steel pipe 600 roll out of the second receiving groove 413, and roll along the third arm 410 onto the first support 100. The inventors discovered that when the third arm 410 is switched to the second position by the second telescopic component 420, the steel pipe 600, which was originally rotating around its own axis of rotation under the drive of the second roller component 400, is lifted away from the second roller component 400. Therefore, it is equivalent to "sudden braking", that is, the rotation of the steel pipe 600 around its own axis stops abruptly, which can easily cause the anti-corrosion layer on the surface of the steel pipe 600 to be scratched by the third arm 410.

[0057] To improve the above issues, please refer to Figure 7 and Figure 8The steel pipe anti-corrosion production equipment 010 in this embodiment also includes an anti-corrosion station 510 located at the end of the first support 100 away from the second support 200. The anti-corrosion station 510 includes a second roller assembly 400, a third support arm 410, a second telescopic assembly 420, and auxiliary rollers 430. The third support arm 410 has a second receiving groove 413 for accommodating the steel pipe 600. One end of the third support arm 410 is rotatably connected to the end of the first support 100 away from the first support arm 310. The second telescopic assembly 420 is in a transmission cooperation with the third support arm 410 to drive the third support arm 410 to switch between a first position and a second position. When the third support arm 410 is in the first position, the second receiving groove 410 is rotatably connected to the end of the first support 100 away from the first support arm 310. The steel pipe 600 in the receiving groove 413 is supported by the second roller assembly 400, and the second roller assembly 400 can drive the steel pipe 600 to rotate around its own rotation axis so as to prepare an anti-corrosion layer on the surface of the rotating steel pipe 600. When the third support arm 410 is in the second position, the steel pipe 600 can roll along the third support arm 410 onto the first support 100. That is, the third support arm 410 can lift the steel pipe 600 away from the second roller assembly 400 and make the steel pipe 600 roll out of the second receiving groove 413 and roll along the third support arm 410 onto the first support 100. The auxiliary roller 430 is rotatably disposed on the third support arm 410 to support the steel pipe 600 located in the second receiving groove 413.

[0058] Since the auxiliary roller 430 is rotatably connected to the third arm 410, when the second telescopic component 420 drives the third arm 410 to switch to the second position to lift the steel pipe 600 away from the second roller assembly 400, the steel pipe 600 can still be supported by the auxiliary roller 430. This allows it to maintain its rotational inertia around its own axis of rotation under the action of the auxiliary roller 430, instead of immediately stopping and causing the surface of the steel pipe 600 to be scratched by the third arm 410 due to the "sudden braking". Afterwards, when the steel pipe 600 rolls and separates from the auxiliary roller 430, the inertia of the steel pipe 600 gradually decreases under the action of gravity, and it will not stop suddenly downward, thus preventing the surface of the steel pipe 600 from being scratched by the third arm 410.

[0059] Optionally, the third arm 410 includes a first arm 411 and a second arm 412 connected at an angle. The third arm 410 is generally V-shaped. The end of the second arm 412 away from the first arm 411 is rotatably connected to the first bracket 100. At least one of the first arm 411 and the second arm 412 is rotatably connected to an auxiliary roller 430.

[0060] The number of auxiliary rollers 430 can be selected as needed. In this embodiment, two auxiliary rollers 430 are rotatably connected to the third arm 410. One auxiliary roller 430 is rotatably connected to the first arm 411, and the other auxiliary roller 430 is rotatably connected to the second arm 412. Both auxiliary rollers 430 can support the steel pipe 600.

[0061] Of course, in other embodiments, the number of auxiliary rollers 430 can be one, three, four, etc., and no specific limitation is made here.

[0062] Optionally, the auxiliary roller 430 is an endurance rubber-coated roller.

[0063] Optionally, the second telescopic component 420 is driven to the connection between the first arm 411 and the second arm 412; when the second telescopic component 420 retracts to drive the third arm 410 to the first position, the second receiving groove 413 formed between the first arm 411 and the second arm 412 is located in a plane lower than the first storage surface 110; when the second telescopic component 420 extends to drive the third arm 410 to the second position, both the first arm 411 and the second arm 412 are raised, and the height of the end of the second arm 412 connected to the first arm 411 is slightly higher than the height of the end of the second arm 412 connected to the first bracket 100, so that the steel pipe 600 supported by the third arm 410 can roll along the second arm 412 onto the first bracket 100.

[0064] The second telescopic assembly 420 includes, but is not limited to, hydraulic hoses and electric push rods.

[0065] The connection methods of the first arm 411 and the second arm 412 include, but are not limited to, integral molding and welding.

[0066] The structure of the second roller assembly 400 is similar to that of the first roller assembly 340, and will not be described in detail here.

[0067] Optionally, when the third arm 410 is in the first position, the end of the second arm 412 away from the first arm 411 protrudes relative to the first support 100 to prevent the steel pipe 600 supported by the first support 100 from rolling back into the second receiving groove 413. When the third arm 410 is in the second position, the end of the second arm 412 away from the first arm 411 is located below the first storage surface 110 or flush with the first storage surface.

[0068] It should be noted that in some other embodiments, the auxiliary roller 430 may not be provided on the third arm 410 of the anti-corrosion station of the steel pipe anti-corrosion production equipment 010, including the tumbling device 300 of this embodiment. In still other embodiments, the steel pipe anti-corrosion production equipment 010 with the auxiliary roller 430 provided on the third arm 410 of the anti-corrosion station may not be equipped with the tumbling device 300 mentioned in the above embodiment.

[0069] The working process of the steel pipe anti-corrosion production equipment 010 in this embodiment includes: placing the steel pipe 600 on the third support arm 410 located in the first position, so as to drive the steel pipe 600 to rotate using the second roller assembly 400, and forming an anti-corrosion layer on the surface of the rotating steel pipe 600; using the second telescopic assembly 420 to drive the third support arm 410 to switch to the second position, so that the steel pipe 600 is lifted by the third support arm 410 and can roll along the second arm 412 of the third support arm 410 onto the first support 100; the steel pipe 600 rolls along the first... The support 100 rolls onto the tumbling device 300. The first telescopic component 330 of the tumbling device 300 causes the connection between the first arm 310 and the second arm 320 to be recessed downwards to receive the steel pipe 600 and to be supported by the first roller assembly 340. After the steel pipe 600 on the tumbling device 300 is polished, the first telescopic component 330 is used to make the connection between the first arm 310 and the second arm 320 protrude upwards, so that the steel pipe 600 can roll along the second arm 320 onto the second support 200.

[0070] In summary, the steel pipe storage rack of this utility model can be used in steel pipe anti-corrosion production equipment 010, and its structure is simple and the cost is low.

[0071] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
