Description

Technical Field

[0001] This utility model relates to the field of steel processing equipment, specifically to a support device for pulling out cast iron pipes. Background Technology

[0002] In the field of cast iron pipe production, centrifuges are the core equipment for forming cast iron pipes. The support and transmission efficiency of the discharge stage directly affects product quality and production continuity. In existing technologies, the centrifuge pipe-extraction process typically uses spaced-apart support components (such as independent bases or roller conveyors) to receive and support the cast iron pipes just taken out of the centrifuge. The main function of these support components is to provide an initial support surface for the discharged cast iron pipes, preventing them from falling directly, and to assist in subsequent conveying or transfer operations.

[0003] Existing support components employ a spaced-out design (e.g., multiple independent bases linearly distributed), with each support component's contact area with the cast iron pipe limited to a local point or short line segment. When the cast iron pipe is first removed from the centrifuge, its temperature is high, and the material is in a semi-solid or plastic state, resulting in weak mechanical properties. At this time, the supporting force of the spaced-out supports is concentrated in a limited contact area, leading to extremely high pressure per unit area. Under this high pressure, the edges or contact points of the supports may embed into the surface of the cast iron pipe, forming dents or indentations. This severely affects the appearance quality and dimensional accuracy of the cast iron pipe. Surface dents may become stress concentration points in the cast iron pipe, easily leading to crack propagation during subsequent transportation, installation, or use (such as under internal pressure or external loads), reducing the pipe's compressive strength and service life, and even causing safety accidents such as leaks and fractures. Utility Model Content

[0004] In view of this, the present invention provides a support device for pulling out cast iron pipes. By using segmented support components and making adjacent segmented support components abut against each other, when the pipe pulling pliers remove the cast iron pipe from the centrifuge, the lifting component drives the base to rise step by step to support the removed cast iron pipe and avoid uneven force on the bottom of the cast iron pipe, which would cause dents.

[0005] To address the aforementioned technical problems, this utility model provides a support device for pulling cast iron pipes, comprising a segmented support component. The segmented support component includes multiple bases located on one side of the centrifuge outlet. These bases provide an installation foundation for subsequent components and form an orderly support. The bases are arranged linearly, which facilitates sequential support of the cast iron pipe along the centrifuge's discharge direction. The orderly spatial distribution of the bases ensures the stability of the overall structure and the continuity of operation. Rollers are rotatably mounted on the bases, symmetrically positioned on both sides of the centrifuge axis. The rotation of the rollers reduces friction during material or component movement, facilitating smooth sliding or transmission. Their symmetrical arrangement on both sides of the centrifuge axis evenly bears the weight of the material or component, preventing offset or tilting due to uneven force, ensuring the stability of the transmission process. Furthermore, it matches the centrifuge's structure, facilitating material output from the outlet.

[0006] A groove is provided near the centrifuge outlet, and the base is arranged in the groove. The groove provides a defined installation space for the base, making the position of the base more precise and ensuring that the relative position with the centrifuge outlet is fixed, so as to accurately receive the materials or parts discharged from the outlet; placing the base in the groove also provides a certain degree of protection for the base, avoiding external collisions or interference, while making the overall structure more compact.

[0007] A lifting assembly is installed at the bottom of the groove, and the bottom of the base is connected to the lifting assembly. The lifting assembly can be adjusted to adapt to centrifuge outlets of different heights or material conveying needs under different working conditions by adjusting the height of the base, thus achieving flexible adjustment of the support height. The connection between the base and the lifting assembly allows each base to be raised or lowered independently or in concert, thereby adjusting the height of each base according to actual needs to optimize the material conveying path or support effect, and enhance the applicability and flexibility of the device.

[0008] The groove has tracks on both sides, and a traction component slides along the tracks. A pipe puller is located near the centrifuge end of the traction component, and the pipe puller is concentrically positioned with the centrifuge. The tracks provide sliding guidance for the traction component, allowing it to move accurately along the centrifuge's discharge direction. The traction component slides, causing the pipe puller to move closer to or away from the centrifuge, enabling manipulation of pipes or components at the centrifuge's discharge port (such as pipe pulling). The concentric positioning of the pipe puller with the centrifuge ensures alignment with the centrifuge's central axis during operation, guaranteeing accuracy and stability, and preventing operational errors or component damage due to positional deviations.

[0009] The end of the pipe puller is equipped with a support ring. The outer surface of the support ring contacts the outer surface of the roller, and the inner surface of the support ring abuts against the outer surface of the pipe puller. The support ring is used to support the pipe puller and prevent the end of the pipe puller from breaking after the cast iron pipe is completely detached from the centrifuge during pipe pulling operations, as the rear end of the cast iron pipe will not be under force.

[0010] Furthermore, it can ensure that the end of the pipe puller swings when it rotates, affecting the concentricity of the pipe puller during rotation.

[0011] The outer surface of the pipe puller is equipped with a limiting block, and the inner surface of the support ring is equipped with a slot. The limiting block slides within the slot, and the two sides of the limiting block abut against the two sides of the slot. The cooperation between the limiting block and the slot forms a limiting structure, restricting the horizontal movement of the support ring on the pipe puller. A baffle is provided on the base near one end of the pipe puller, located between symmetrically arranged rollers. The baffle can block the side of the support ring near the pipe puller, causing the support ring to move away from the traction assembly as the pipe puller moves. This ensures that the outer surface of the support ring always abuts against the outer surface of the rollers when pulling the cast iron pipe, thus supporting the pipe puller.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. Segmented support and roller design: Multiple bases are arranged linearly and rollers are symmetrically set on both sides of the centrifuge axis to form a segmented support structure. Compared with the existing spaced support components, this increases the contact area with the cast iron pipe, disperses gravity to reduce local pressure, and reduces the risk of surface dents.

[0014] 2. The groove is combined with the lifting component: The base is located in the groove and connected to the lifting component. The height of the base can be adjusted by lifting to adapt to the processing needs of different specifications of pipes, thereby enhancing the versatility and flexibility of the equipment.

[0015] 3. Track and traction components work together: The traction components on both sides of the groove are equipped with tube pullers, and the tube pullers are concentrically set with the centrifuge, which can achieve precise positioning and stable traction of the tube pulling action, and improve the efficiency and accuracy of tube pulling.

[0016] 4. Support ring and limiting block structure: The support ring at the end of the pipe pulling wrench contacts the roller, and the limiting block cooperates with the slot, which may provide better support and limiting for the pipe during the pipe pulling process, ensuring the stability of the pipe pulling process and reducing the risk of pipe damage.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figures 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] like Figure 1 , 2 As shown in Figure 3:

[0023] This embodiment provides a support device for pulling cast iron pipes, including a segmented support 100. The segmented support 100 is located below the centrifuge, allowing the pipe pulling pliers 4 to move forward and clamp the cast iron pipe. When the pipe pulling pliers 4 pulls the cast iron pipe out, the segmented support 100 near the centrifuge is driven by the lifting assembly 104 to contact the outer surface of the cast iron pipe. As the traction assembly 3 pulls the cast iron pipe away from the centrifuge and moves backward, the segmented support 100 located below the centrifuge moves upward step by step to support the outer surface of the cast iron pipe. The contact part between the separated cast iron pipe and the cast iron pipe is a roller 102. The end faces of adjacent rollers 102 abut against each other, so that the rollers 102 are arranged in a straight line, which can fully support the contact part between the cast iron pipe and the rollers 102, avoiding dents on the outer surface of the cast iron pipe due to the large distance between the support components.

[0024] like Figure 1 , 3 As shown:

[0025] The segmented support component 100 includes multiple bases 101, which are located on one side of the centrifuge outlet and arranged linearly. This linear arrangement is consistent with the centrifuge's discharge direction, facilitating the sequential support of the cast iron pipes along this direction and ensuring orderly support during transport. The orderly spatial distribution of the bases 101 not only provides a stable installation foundation for subsequent components but also ensures the stability of the overall structure through a reasonable layout, enabling continuous operation and avoiding structural instability or operational interruptions caused by a disorderly distribution of the bases 101.

[0026] like Figure 2 , 3 As shown:

[0027] A roller 102 is rotatably mounted on the base 101. A semi-circular bracket is connected to the base surface of the roller 102. The outer surface of the roller 102 abuts against the inner surface of the semi-circular bracket. An annular groove is present on the outer surface of the roller 102, and a locking block is present on the inner surface of the semi-circular bracket. The two ends of the locking block abut against the base surfaces on both sides of the annular groove, limiting the roller 102 and allowing it to rotate at the same position on the semi-circular bracket. The rollers 102 are symmetrically arranged on both sides of the centrifuge axis. The rotation of the rollers 102 reduces friction during material or component movement, allowing for smooth sliding or transmission. The symmetrical arrangement evenly distributes the weight of the material or component, preventing offset or tilting due to uneven force and ensuring stable transmission. Furthermore, this symmetrical arrangement matches the centrifuge structure, facilitating material output from the discharge port and ensuring that the material discharged from the centrifuge outlet falls smoothly onto the rollers 102 for transmission.

[0028] like Figure 1 , 2 As shown in Figure 3:

[0029] A groove 103 is provided near the centrifuge outlet, and the base 101 is arranged within the groove 103. The groove 103 provides a defined installation space for the base 101. This defined space allows for more precise positioning of the base 101, ensuring a fixed relative position with the centrifuge outlet, thus facilitating accurate reception of materials or components discharged from the outlet. Placing the base 101 within the groove 103 not only achieves precise positioning but also provides some protection for the base 101, preventing it from being subjected to external collisions or interference. Simultaneously, it makes the overall structure more compact, reduces wasted space, and improves the space utilization rate of the device.

[0030] like Figure 1 , 2 As shown in Figure 3:

[0031] A lifting assembly 104 is provided at the bottom of the groove 103. The lifting assembly 104 can be operated using components such as cylinders, and the bottom of the base 101 is connected to the lifting assembly 104. The lifting assembly 104 allows the height of the base 101 to be adjusted, which can adapt to different centrifuge discharge ports of different heights or material conveying requirements under different working conditions, achieving flexible adjustment of the support height. Since each base 101 is connected to the lifting assembly 104, each base 101 can be raised and lowered independently or collaboratively. This allows the height of each base 101 to be adjusted according to actual needs to optimize the material conveying path or support effect, enhancing the applicability and flexibility of the device, enabling it to function in a variety of different working scenarios.

[0032] like Figure 1 ,2 As shown in Figure 3:

[0033] Tracks 2 are provided on both sides of the groove 103. A traction assembly 3 is slidably mounted on the tracks 2. The traction assembly 3 includes a tube-pulling trolley, which slides on the tracks 2. A motor is installed at the end of the tube-pulling trolley away from the tracks 2. A tube-pulling clamp 4 is connected to the motor output end via a flange, facilitating disassembly and replacement of the clamp 4. A cylinder is connected to the end of the tube-pulling trolley away from the clamp 4, which drives the tube-pulling trolley to move back and forth, removing the cast iron pipe from the centrifuge. The tube-pulling clamp 4 is located at the end of the traction assembly 3 closest to the centrifuge and is concentrically positioned with the centrifuge. The tracks 2 provide sliding guidance for the traction assembly 3, enabling it to move accurately along the centrifuge's discharge direction. By sliding on the tracks 2, the traction assembly 3 can move the tube-pulling clamp 4 closer to or away from the centrifuge, thereby enabling operations on pipes or components at the centrifuge outlet, such as tube pulling. The tube-pulling clamp 4 is concentrically positioned with the centrifuge, ensuring that it is aligned with the centrifuge's central axis during operation. This guarantees the accuracy and stability of the operation, avoids operational errors or component damage caused by positional deviations, and enables tube-pulling operations to be performed safely and reliably.

[0034] like Figure 1 , 2 As shown in Figure 3:

[0035] The pipe puller 4 has a support ring 5 at its end. The outer surface of the support ring 5 contacts the outer surface of the roller 102, and the inner surface of the support ring abuts against the outer surface of the pipe puller 4. The main function of the support ring 5 is to support the pipe puller 4. During pipe pulling operations, after the cast iron pipe is completely removed from the centrifuge, it prevents the rear end of the cast iron pipe from being unloaded, resulting in uneven force on the pipe puller 4 and causing the end of the pipe puller 4 to break. At the same time, the support ring 5 also ensures that the end of the pipe puller 4 does not swing when it rotates, thus affecting the concentricity of the pipe puller 4 during rotation, ensuring that the pipe puller 4 remains stable during rotation, and improving the accuracy and reliability of the operation.

[0036] like Figure 3 As shown:

[0037] The outer surface of the pipe puller 4 is provided with a limiting block 6, and the inner surface of the support ring 5 is provided with a slot 7. The limiting block 6 slides within the slot 7, and the two sides of the limiting block 6 abut against the two sides of the slot 7. This cooperation between the limiting block 6 and the slot 7 forms a limiting structure, restricting the horizontal movement of the support ring 5 on the pipe puller 4, ensuring that the position of the support ring 5 on the pipe puller 4 is relatively fixed and will not move horizontally. A baffle 8 is provided on the base 101 near one end of the pipe puller 4. The baffle 8 is located between the symmetrically arranged rollers 102 and can block the side of the support ring 5 near the end of the pipe puller 4. When the pipe puller 4 moves away from the traction component 3, the blocking effect of the baffle 8 ensures that the outer surface of the support ring 5 always abuts against the outer surface of the roller 102 when pulling the cast iron pipe, thereby continuously supporting the pipe puller 4 and ensuring the smooth progress of the pipe pulling operation.

[0038] Working Principle: Multiple bases 101 of the segmented support component 100 are linearly arranged in a groove 103 on one side of the centrifuge outlet. Symmetrically arranged rollers 102 on the bases 101 are rotatable and support the pipe. A lifting assembly 104 at the bottom of the groove 103 adjusts the height of the bases 101 to accommodate pipes of different sizes. Traction assemblies 3 on the tracks 2 on both sides of the groove 103 slide to move the pipe puller 4. The pipe puller 4 is concentrically positioned with the centrifuge for precise alignment of the pipe. A rotatable support ring 5 at the end of the pipe puller 4 contacts the outer surface of the roller 102. When the traction assembly 3 pulls, the support ring 5 rotates through a sliding engagement between the limiting block 6 and the slot 7 of the pipe puller 4, reducing friction during pipe extraction. A baffle 8 is installed on the base 101 near the pipe puller 4, located between the symmetrical rollers 102, to limit the pipe position and ensure stability during the extraction process. The entire system achieves stable support and efficient extraction of the centrifuge outlet pipe through the coordinated action of its components.

[0039] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
