Abstract
Description
Technical Field
[0001] This application relates to the technical field of steel pipe processing equipment, specifically a vertical uncoiling device. Background Technology
[0002] Steel pipes, as an important basic industrial material, are widely used in many fields such as petroleum, natural gas, construction, machinery manufacturing, automobiles, and aerospace. With the acceleration of global industrialization and the continuous advancement of infrastructure construction, the market demand for steel pipes continues to grow. Steel pipes are generally processed from strip steel during the production process. In the production of steel pipes, lifting equipment and chains are used to lift the strip steel to a vertical uncoiling device for uncoiling.
[0003] When the existing vertical uncoiling device is hoisted onto the device, the strip steel presses down on the chain, making it difficult to pull the chain hanging on the strip steel out from between the strip steel and the uncoiling device. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a vertical uncoiling device that allows for a certain gap between the strip steel and the support plate when the strip steel is placed on the support plate of the uncoiling device. This allows the chain hanging on the strip steel to be easily pulled out from between the strip steel and the support plate of the uncoiling device, preventing the presence of the chain from affecting the normal uncoiling of the strip steel. This solves the problem in existing vertical uncoiling devices where the strip steel is pressed on top of the chain when it is hoisted onto the device, making it difficult to pull the chain hanging on the strip steel out from between the strip steel and the uncoiling device.
[0005] To achieve the aforementioned goal of ensuring a certain gap between the strip steel and the support plate when the strip steel is placed on the support plate of the uncoiling device, allowing the chain hanging on the strip steel to be easily pulled out from between the strip steel and the support plate of the uncoiling device, and preventing the presence of the chain from affecting the normal uncoiling of the strip steel, this application provides the following technical solution: a vertical uncoiling device, including a base, a rotating shaft provided at the top of the base, a support plate rotatably provided at the top of the rotating shaft, and four bosses provided at the top of the support plate, the four bosses being distributed in a circular array on the top of the support plate, with a gap between the ends of the four bosses that are close to each other.
[0006] A positioning post is provided at the top center of the support plate. Four positioning claws are provided on the outer side of the positioning post. A first swing rod is hinged to the side of the positioning claws near the positioning post through a hinge frame. The end of the first swing rod away from the positioning claws is hinged to the side of the connecting plate through the hinge frame. One end of the connecting plate is provided at the bottom of the positioning frame. A fixing frame is provided at the top of the positioning frame. The end of the fixing frame away from the positioning frame is provided on the middle outer surface of the push plate. The middle inner wall of the push plate is threaded to the middle outer surface of the threaded rod. One end of the threaded rod is rotatably provided at the top of the positioning post.
[0007] The above solution uses four protrusions on the top of the support plate to support the strip steel, increasing the gap between the strip steel and the support plate. This provides stable support for the strip steel while preventing it from pressing on the chain. This ensures that when the strip steel is placed on the support plate of the uncoiling device, there is a certain gap between the strip steel and the support plate, allowing the chain hanging on the strip steel to be easily pulled out from between the strip steel and the support plate of the uncoiling device. This prevents the presence of the chain from affecting the normal uncoiling effect of the strip steel.
[0008] Furthermore, a second swing rod is hinged to one end of the positioning claw away from the first swing rod via a hinge frame, and the end of the second swing rod away from the positioning claw is hinged to one end of the connecting plate away from the first swing rod via a hinge frame.
[0009] With the above scheme, when the second swing rod swings in conjunction with the first swing rod, both ends of the positioning claw can be pushed simultaneously, thereby improving the stability of the positioning claw in clamping and positioning the center of the strip coil.
[0010] Furthermore, the first swing rod and the second swing rod, which are hinged at both ends on one side of the positioning claw, are arranged parallel to each other.
[0011] The above scheme allows the positioning claw to remain vertical during movement by setting the first and second swing rods parallel to each other. This enables the two ends of the positioning claw to be balanced by the swinging of the first and second swing rods, thereby improving the stability of the positioning claw during movement.
[0012] Furthermore, a telescopic rod is provided between the positioning claw and the side corresponding to the positioning post. One end of the telescopic rod's outer telescopic tube is located on one side of the positioning post, and one end of the telescopic rod's inner telescopic tube is located on one side of the positioning claw.
[0013] The above scheme uses a telescopic rod to fix the movement trajectory of the positioning claw, so that when the first swing rod swings in conjunction with the second swing rod, it can stably push the positioning claw toward the inner wall of the center of the steel coil.
[0014] Furthermore, the four positioning claws are arranged in a circular array on the outside of the positioning post, and the positions of the four positioning claws correspond to the positions of the four protrusions, with gaps between the four positioning claws.
[0015] The above solution, with four positioning claws corresponding to the positions of the four bosses and gaps between the four positioning claws, can prevent the position of the positioning claws from affecting the extraction of the chain hanging on the strip.
[0016] Furthermore, the inner wall of the middle part of the positioning frame is slidably disposed on the outer surface of the middle part of the positioning post. The positioning post is quadrilateral in shape, and the shape of the outer surface of the middle part of the positioning post is adapted to the shape of the inner wall of the middle part of the positioning frame.
[0017] The above solution, by matching the shape of the positioning column with the positioning frame, can fix the trajectory of the positioning frame when it slides on the outer surface of the middle part of the positioning column, which can improve the stability of the positioning frame when it drives the connecting plate to move, and thus improve the stability of the connecting plate when it drives the first swing rod and the second swing rod to swing.
[0018] Furthermore, a handle is provided at the end of the threaded rod away from the positioning post.
[0019] The above solution allows for easier rotation of the threaded rod through the addition of a handle, thus improving the convenience of operating the threaded rod.
[0020] Furthermore, the boss is made of hot-formed steel.
[0021] By adopting the above solution and using hot-formed steel, the structural strength and wear resistance of the boss can be significantly improved, making it less prone to deformation or damage when subjected to long-term strip pressure. This ensures the stability of the gap between the strip and the support plate and improves the service life of the boss.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This vertical uncoiling device supports the strip steel through four protrusions on the top of the support plate. The protrusions increase the gap between the strip steel and the support plate, providing stable support for the strip steel while preventing the strip steel from pressing on the chain. This ensures that when the strip steel is placed on the support plate of the uncoiling device, there is a certain gap between the strip steel and the support plate, allowing the chain hanging on the strip steel to be easily pulled out from between the strip steel and the support plate of the uncoiling device. This prevents the presence of the chain from affecting the normal uncoiling effect of the strip steel.
[0024] This vertical uncoiling device allows the push plate to move in conjunction with the fixed frame by rotating the threaded rod, which in turn causes the connecting plate to swing the first swing rod, adjusting the position of the positioning claw. This allows the positioning claw to clamp and position the center of the strip coil, improving the stability of the strip coil during uncoiling on the support plate. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0033] Please see Figure 1 , Figure 2 and Figure 5 The vertical unwinding device in this embodiment includes a base 1, a rotating shaft 2 is provided on the top of the base 1, a support plate 3 is rotatably provided on the top of the rotating shaft 2, and four protrusions 4 are provided on the top of the support plate 3. The four protrusions 4 are arranged in a circular array on the top of the support plate 3, and a gap is provided between the ends of the four protrusions 4 that are close to each other.
[0034] Please see Figure 1 , Figure 2 and Figure 3 A positioning post 5 is provided at the top center of the support plate 3. Four positioning claws 6 are provided on the outer side of the positioning post 5. The first swing rod 7 is hinged to the side of the positioning claw 6 near the positioning post 5 through a hinge frame. The end of the first swing rod 7 away from the positioning claw 6 is hinged to the side of the connecting plate 8 through the hinge frame. One end of the connecting plate 8 is provided at the bottom of the positioning frame 9. A fixing frame 14 is provided at the top of the positioning frame 9. The end of the fixing frame 14 away from the positioning frame 9 is provided on the middle outer surface of the push plate 10. The middle inner wall of the push plate 10 is threaded to the middle outer surface of the threaded rod 11. One end of the threaded rod 11 is rotatably provided at the top of the positioning post 5.
[0035] Please see Figure 1 and Figure 4The end of the positioning claw 6 away from the first swing rod 7 is hinged to the second swing rod 13 through the hinge frame. The end of the second swing rod 13 away from the positioning claw 6 is hinged to the end of the connecting plate 8 away from the first swing rod 7 through the hinge frame. When the second swing rod 13 swings in conjunction with the first swing rod 7, it can push both ends of the positioning claw 6 at the same time, thereby improving the stability of the positioning claw 6 in clamping and positioning the center of the strip coil.
[0036] Please see Figure 1 and Figure 4 The first swing rod 7 and the second swing rod 13, which are hinged at both ends on one side of the positioning claw 6, are arranged parallel to each other. The parallel arrangement between the first swing rod 7 and the second swing rod 13 can keep the positioning claw 6 in a vertical state when moving, so that the two ends of the positioning claw 6 can be balanced by the swing of the first swing rod 7 and the second swing rod 13, thereby improving the stability of the positioning claw 6 when moving.
[0037] Please see Figure 1 , Figure 2 and Figure 3 A telescopic rod 12 is provided between the positioning claw 6 and the corresponding side of the positioning post 5. One end of the telescopic rod 12 is located on one side of the positioning post 5, and one end of the telescopic rod 12 is located on one side of the positioning claw 6. The telescopic rod 12 can fix the movement trajectory of the positioning claw 6, so that when the first swing rod 7 swings in conjunction with the second swing rod 13, it can stably push the positioning claw 6 to move towards the center inner wall of the steel coil.
[0038] Please see Figure 1 , Figure 2 and Figure 3 Four positioning claws 6 are arranged in a ring array on the outside of the positioning post 5. The positions of the four positioning claws 6 correspond to the positions of the four protrusions 4. There is a gap between the four positioning claws 6. By having the four positioning claws 6 correspond to the positions of the four protrusions 4 and the four positioning claws 6 have gaps between them, the position of the positioning claws 6 can be prevented from affecting the extraction of the chain hanging on the strip.
[0039] Please see Figure 1 , Figure 3 and Figure 4 The inner wall of the middle part of the positioning frame 9 is slidably disposed on the outer surface of the middle part of the positioning post 5. The positioning post 5 is quadrilateral, and the shape of the outer surface of the middle part of the positioning post 5 is adapted to the shape of the inner wall of the middle part of the positioning frame 9. By matching the shape of the positioning post 5 with the positioning frame 9, the trajectory of the positioning frame 9 when sliding on the outer surface of the middle part of the positioning post 5 can be fixed, which can improve the stability of the positioning frame 9 when it drives the connecting plate 8 to move, and thus improve the stability of the connecting plate 8 when it drives the first swing rod 7 and the second swing rod 13 to swing.
[0040] Please see Figure 1 ,Figure 2 and Figure 3 A handle 15 is provided at the end of the threaded rod 11 away from the positioning post 5. The handle 15 makes it easier to rotate the threaded rod 11, thus improving the ease of operation of the threaded rod 11.
[0041] Please see Figure 1 , Figure 2 and Figure 5 The boss 4 is made of hot-formed steel. By using hot-formed steel, the structural strength and wear resistance of the boss 4 can be significantly improved, making it less prone to deformation or damage when subjected to long-term strip pressure, thereby ensuring the stability of the gap between the strip and the support plate 3 and improving the service life of the boss 4.
[0042] In this embodiment, a vertical uncoiling device supports the strip steel using four protrusions 4 on the top of the support plate 3. These protrusions increase the gap between the strip steel and the support plate 3, providing stable support while preventing the strip steel from pressing against the chain. This ensures a certain gap between the strip steel and the support plate 3 when placed on the uncoiling device, allowing the chain hanging on the strip steel to be easily pulled out from between the strip steel and the support plate 3. The presence of the chain prevents it from affecting the normal uncoiling effect. Rotating the threaded rod 11 causes the push plate 10, in conjunction with the fixing frame 14, to move the positioning frame 9. This, in turn, causes the connecting plate 8 to swing the first swing rod 7, adjusting the position of the positioning claw 6. The positioning claw 6 then clamps and positions the center of the strip steel coil, improving the stability of the strip steel coil during uncoiling on the support plate 3.
[0043] It should be noted that the thickness of boss 4 is greater than the thickness of the lifting chain.
[0044] The working principle of the above embodiment is as follows: A lifting device and chain are used to hoist the strip steel onto the top of the boss 4 on the support plate 3. The chain is aligned with the gaps between the four bosses 4 and the four positioning claws 6. After placing the strip steel on the top of the bosses 4, a certain gap is created between the strip steel and the support plate 3. The chain hanging on the strip steel is then pulled out from the gap between the strip steel and the support plate 3. The handle 15 is rotated, causing the threaded rod 11 to rotate, which in turn moves the push plate 10 downwards. The push plate 10, through the fixing frame 14, moves the positioning frame 9 downwards. The positioning frame 9 drives four sets of first swing rods 7 and second swing rods 13 to swing through the four connecting plates 8. When the first swing rod 7 swings in conjunction with the second swing rod 13, it pushes the corresponding positioning claw 6 away from the positioning post 5, pushing the four positioning claws 6 to move towards the inner wall of the strip center. At the same time, when the positioning claw 6 moves, it will cause the telescopic rod 12 to extend until the side of the positioning claw 6 away from the positioning post 5 is attached to the inner wall of the strip center. Through the cooperation of the four positioning claws 6, the center of the strip is clamped and positioned, fixing the strip above the support plate 3.
