Description

Technical Field

[0001] This utility model relates to the technical field of pipeline processing equipment, specifically to a belt centrifugal rotary device for pipelines. Background Technology

[0002] In pipeline manufacturing and subsequent processing, such as anti-corrosion spraying, insulation wrapping, non-destructive testing, or surface cleaning, it is usually necessary to drive the pipeline to rotate at a constant speed around its own axis to ensure uniform processing and improve work quality and efficiency.

[0003] Currently, the main device for rotating pipes is the roller-type rotating device. This typically consists of two or four sets of freely rotating rollers forming a V-shaped or saddle-shaped support. The pipe is supported on this support, and its rotation is driven by an external drive device (such as a motor-driven friction wheel) directly contacting the pipe surface. The disadvantages of this structure are: First, poor clamping stability: The pipe relies solely on gravity to rest on the rollers, making it prone to axial movement or radial runout during high-speed rotation or starting / braking, affecting processing accuracy and even posing a risk of detachment. Second, limited adaptability: The spacing and angle of each set of rollers are usually fixed, making it difficult to quickly adapt to pipes of different diameters. Changing products requires stopping the machine for complex mechanical adjustments, which is time-consuming and labor-intensive, impacting production efficiency. Third, prone to slippage: When relying on friction wheel drive, the contact area and positive pressure are limited. Slippage easily occurs when encountering oily or uneven pipe surfaces, leading to uneven pipe rotation and affecting coating and other treatment effects. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A belt-type centrifugal rotary device for pipelines includes multiple parallel roller supports. A first roller and a second roller are rotatably connected to the left and right ends of each roller support via bearing seats. The first roller and the second roller are connected by a transmission belt. The central axis of the first roller is connected to the output shaft of a drive motor. A left support frame is fixedly installed on the upper side of each roller support near the first roller. A third roller is rotatably connected to the left support frame via a bearing seat. A right support frame is fixedly installed on the upper side of each roller support near the second roller. A fourth roller is rotatably connected to the right support frame via a bearing seat. Both the third and fourth rollers are pressed tightly against the upper part of the transmission belt.

[0007] A first adjusting frame and a second adjusting frame are provided between the third and fourth rollers. The first and second adjusting frames are rotatably connected to the roller support above the rollers via rotating shaft seats. A fifth roller is rotatably connected to the first adjusting frame via a bearing seat, and a sixth roller is rotatably connected to the second adjusting frame via a bearing seat. The upper surfaces of the fifth and sixth rollers are in contact with the transmission belt for transmission. A gap is left between the fifth and sixth rollers for placing a pipe. The pipe is located above the transmission belt so that it is driven to rotate with the movement of the transmission belt.

[0008] Preferably, the sides of the first adjusting frame and the second adjusting frame are rotatably connected to one end of the first cylinder and one end of the second cylinder via rotating shaft seats, and the other ends of the first cylinder and the other ends of the second cylinder are respectively hinged to the roller bracket via rotating shaft seats.

[0009] Preferably, the sides of the first adjusting frame and the second adjusting frame are rotatably connected to one end of the first adjusting rod and one end of the second adjusting rod via a rotating shaft seat, respectively. The first adjusting rod is arranged parallel to the first cylinder, and the second adjusting rod is arranged parallel to the second cylinder. The other ends of the first adjusting rod and the other ends of the second adjusting rod are both hinged to the roller bracket via a rotating shaft seat.

[0010] Preferably, there are two sets of the first adjusting rod and the second adjusting rod, and each of the first adjusting rod and the second adjusting rod includes an upper sleeve rod and a lower insert rod. The upper sleeve rod has a telescopic cavity that cooperates with the lower insert rod. The lower insert rod can slide axially into the upper sleeve rod. The side surfaces of the upper sleeve rod and the lower insert rod are provided with several corresponding limiting holes. The relative positions of the upper sleeve rod and the lower insert rod are fixed by inserting a pin into the limiting holes.

[0011] Preferably, the upper roller and the lower roller are rotatably connected to the left and right sides of the inner cavity of the roller bracket via a rotating shaft. The upper roller and the lower roller are respectively in contact with the inner and outer surfaces of the transmission belt for limiting and guiding the transmission belt. The upper roller and the lower roller are symmetrically arranged in the vertical direction. The rotation axes of the upper roller and the lower roller are parallel to the rotation axes of the first roller and the second roller, and are both perpendicular to the transmission direction.

[0012] Preferably, guide slide rods are provided on both the front and rear surfaces of the right end of the roller bracket. The guide slide rods extend along the left and right direction of the roller bracket. The two ends of the guide slide rods are fixedly installed on the side of the roller bracket by fixing seats.

[0013] Preferably, a plurality of support rollers are rotatably connected to the bottom of the inner cavity of the roller bracket. The support rollers are evenly distributed along the outer surface of the transmission belt to support the lower running section of the transmission belt and prevent it from sagging and deforming during operation.

[0014] This invention provides a belt-driven centrifugal rotary device for pipelines, offering the following advantages: A dynamically adjustable V-shaped clamping mechanism is formed by a first adjusting frame, a second adjusting frame, and the fifth and sixth rollers driven by them. By controlling the strokes of the first and second cylinders, the distance between the two rollers can be precisely and quickly adjusted, perfectly adapting to pipelines of different diameters. This effectively meets the processing needs of various pipe diameters, achieving multi-purpose functionality, greatly improving equipment utilization and production flexibility, and saving downtime for adjustments due to product specification changes. Furthermore, by using a transmission belt as the driving medium, its contact with the pipeline surface is a surface contact, rather than a point or line contact, significantly increasing the effective contact area and friction. Combined with the pressure applied from above by the third and fourth rollers, the wrap angle of the transmission belt around the pipeline is further increased, greatly improving the reliability and efficiency of the transmission and effectively avoiding problems such as uneven pipeline speed and poor processing results caused by slippage.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] Example 1, as Figure 1-5 As shown, a belt centrifugal rotary device for pipelines includes multiple parallel roller supports 1. The left and right ends of the roller supports 1 are rotatably connected to a first roller 2 and a second roller 3 via bearing seats, respectively. The first roller 2 and the second roller 3 are connected by a transmission belt 4. The central axis of the first roller 2 is connected to the output shaft of a drive motor 23. A left support frame 5 is fixedly installed on the side of the roller supports 1 near the first roller 2. A third roller 6 is rotatably connected to the left support frame 5 via a bearing seat. A right support frame 7 is fixedly installed on the side of the roller supports 1 near the second roller 3. A fourth roller 8 is rotatably connected to the right support frame 7 via a bearing seat. The third roller 6 and the fourth roller 8 are both pressed against the top of the transmission belt 4.

[0025] A first adjusting frame 9 and a second adjusting frame 10 are provided between the third roller 6 and the fourth roller 8. The first adjusting frame 9 and the second adjusting frame 10 are rotatably connected to the roller support 1 above the roller support 1 via a rotating shaft seat. A fifth roller 11 is rotatably connected to the first adjusting frame 9 via a bearing seat. A sixth roller 12 is rotatably connected to the second adjusting frame 10 via a bearing seat. The upper surfaces of the fifth roller 11 and the sixth roller 12 are in contact with the transmission belt 4 for transmission. A gap is left between the fifth roller 11 and the sixth roller 12 for placing the pipe 30. The pipe 30 is located above the transmission belt 4 so that it can be driven to rotate with the movement of the transmission belt 4.

[0026] In this embodiment, the sides of the first adjustment frame 9 and the second adjustment frame 10 are rotatably connected to one end of the first cylinder 13 and one end of the second cylinder 14 via a rotating shaft seat, and the other ends of the first cylinder 13 and the second cylinder 14 are respectively hinged to the roller bracket 1 via a rotating shaft seat.

[0027] Working principle:

[0028] During operation, the pipe 30 to be processed is first placed in the gap between the fifth roller 11 and the sixth roller 12 above each roller support 1. The weight of the pipe 30 presses it against the transmission belt 4 below, ensuring close contact between the lower surface of the pipe 30 and the transmission belt 4. Then, depending on the diameter of the pipe 30, the first cylinder 13 and the second cylinder 14 are activated. The extension and retraction of the first cylinder 13 drives the first adjusting frame 9 to rotate around its pivot, thereby causing the fifth roller 11 to swing. Similarly, the extension and retraction of the second cylinder 14 drives the second adjusting frame 10 to rotate, thus adjusting the position of the sixth roller 12. By controlling the synchronous or independent action of the first cylinder 13 and the second cylinder 14, the horizontal distance between the fifth roller 11 and the sixth roller 12 can be precisely adjusted, ensuring they fit snugly against and slightly press against the pipe 30 from both sides, forming a stable V-shaped or arc-shaped support structure. This accommodates various pipe diameters from the smallest to the largest design range.

[0029] After positioning and clamping the pipe 30, the drive motor 23 is started. The output shaft of the drive motor 23 drives the first roller 2 to rotate, and the friction between the first roller 2 and the transmission belt 4 drives the transmission belt 4 to make a circular motion. During the movement, the upper running section of the transmission belt 4 is in direct contact with the bottom of the pipe 30. Thus, the friction between the transmission belt 4 and the pipe 30 can drive the pipe 30 to rotate around its own axis. During this process, the third roller 6 and the fourth roller 8 press the transmission belt 4 from above, ensuring the envelope angle and contact area of ​​the contact section between the transmission belt 4 and the pipe 30, thereby increasing the effective driving force.

[0030] This invention comprises a first adjusting frame 9, a second adjusting frame 10, and their driven fifth roller 11 and sixth roller 12, forming a dynamically adjustable V-shaped clamping mechanism. By controlling the stroke of the first cylinder 13 and the second cylinder 14, the distance between the two rollers can be precisely and quickly adjusted, perfectly adapting to pipes of different diameters. This effectively meets the processing needs of various pipe diameters, solving the problems of traditional roller support devices requiring mechanical adjustment and having poor adaptability. It achieves multi-purpose functionality, greatly improving equipment utilization and production flexibility, and saving downtime for adjustments due to product specification changes. Furthermore, by using a transmission belt 4 as the driving medium, its contact with the pipe surface is a surface contact, rather than a point or line contact, significantly increasing the effective contact area and friction. Combined with the pressure applied from above by the third roller 6 and the fourth roller 8, the wrap angle of the transmission belt 4 around the pipe 30 is further increased, greatly improving the reliability and efficiency of the transmission and effectively avoiding problems such as uneven pipe rotation speed and poor processing effect caused by slippage.

[0031] In Embodiment 2, as a further preferred embodiment of Embodiment 1, the sides of the first adjusting frame 9 and the second adjusting frame 10 are respectively rotatably connected to one end of the first adjusting rod 17 and one end of the second adjusting rod 18 via a rotating shaft seat. The first adjusting rod 17 is arranged parallel to the first cylinder 13, and the second adjusting rod 18 is arranged parallel to the second cylinder 14. The other ends of the first adjusting rod 17 and the second adjusting rod 18 are both hinged to the roller bracket 1 via a rotating shaft seat.

[0032] Since the cylinder itself is the power source, its cylinder rod has limited capacity to withstand radial forces. When the pipeline rotates and generates vibrations or radial forces, a single cylinder hinge point may become a weak point in rigidity, causing slight wobbling or "nodding" of the adjusting frame. Therefore, by adding a first adjusting rod 17 and a second adjusting rod 18 to the sides of the first adjusting frame 9 and the second adjusting frame 10 respectively, a parallelogram linkage mechanism is formed, effectively distributing the radial load borne by the cylinder, significantly extending the service life of pneumatic components, and reducing maintenance costs. It also greatly enhances the bending and torsional stiffness of the entire adjusting mechanism, effectively ensuring the stability of the pipeline under high-speed rotation. Furthermore, in extreme cases, such as air source failure, control system malfunction, or maintenance requirements, the adjusting rod mechanism can serve as a reliable mechanical lock or safety backup. Operators can even manually (after depressurizing the cylinder rodless chamber) roughly position and fix the adjusting frame based on the adjusting rod structure, ensuring that the equipment still possesses a certain degree of functionality or safety under abnormal conditions, thus improving the reliability of the equipment.

[0033] In Example 3, as a further preferred embodiment of Example 1, two sets of the first adjusting rod 17 and the second adjusting rod 18 are provided. Both the first adjusting rod 17 and the second adjusting rod 18 include an upper sleeve rod and a lower insert rod. The upper sleeve rod has a telescopic cavity that mates with the lower insert rod. The lower insert rod can slide axially into the upper sleeve rod. Several corresponding limiting holes are provided on the side surfaces of both the upper sleeve rod and the lower insert rod. The relative positions of the upper sleeve rod and the lower insert rod are fixed by inserting a pin into the limiting holes. By configuring two sets of parallel and symmetrically distributed adjusting rods for both the first adjusting rod 17 and the second adjusting rod 18, a statically indeterminate stable support system is formed. This greatly suppresses torsional deformation and lateral bending in any direction. This gives the entire clamping unit unparalleled rigidity and stability when facing centrifugal force, vibration, or accidental impacts generated by the high-speed rotation of the pipeline, ensuring the absolute fixation of the pipeline's axial position and thus guaranteeing the highest standard of machining accuracy. Furthermore, by designing the upper sleeve rod and lower insertion rod as telescopic structures, and combining them with a limiting hole and a pin, not only can the length of the adjusting rod be flexibly adjusted, but the position can also be locked by the pin after adjustment, forming a rigid support. Thus, when the cylinder is inflated and maintaining a clamping state, the mechanical locking of the adjusting rod acts as a redundant safety barrier, preventing the instantaneous loss of clamping force caused by sudden air leakage, air pipe rupture, or control system malfunction leading to a loss of air pressure, avoiding major safety accidents such as pipe detachment or flying out. In addition, when the equipment maintains a single pipe diameter for a long period, the pin can be used to lock the cylinder, completely unloading it and leaving it in a pressure-free state, thereby extending cylinder life and saving energy.

[0034] In Example 4, as a further preferred embodiment of Example 1, upper rollers 19 and lower rollers 20 are rotatably connected to the left and right sides of the inner cavity of the roller bracket 1 via rotating shafts. The upper rollers 19 and 20 respectively contact the inner and outer surfaces of the transmission belt 4 for limiting and guiding the transmission belt 4. The upper rollers 19 and 20 are symmetrically arranged vertically, and their rotation axes are parallel to the rotation axes of the first roller 2 and the second roller 3, and both are perpendicular to the transmission direction. Through the combined action of the upper rollers 19 and 20, a precise limiting channel is formed in the width direction of the transmission belt 4. The upper roller 19 restricts the upward or inward movement of the transmission belt, while the lower roller 20 restricts its downward or outward movement. This completely eliminates the lateral slippage (deviation) that inevitably occurs during operation due to uneven tension, manufacturing deviations, or load changes. It ensures that the transmission belt 4 always runs smoothly along the predetermined center trajectory, greatly improving the stability and synchronization accuracy of the transmission system.

[0035] In Example 5, as a further preferred embodiment of Example 1, guide slide rods 15 are provided on both the front and rear surfaces of the right end of the roller bracket 1. The guide slide rods 15 extend along the left-right direction of the roller bracket 1, and both ends of the guide slide rods 15 are fixedly mounted on the sides of the roller bracket 1 via fixed seats. Sliding seats 16 are slidably connected to the guide slide rods 15. Both ends of the second roller 3 are respectively mounted on the sliding seats 16 via bearing seats. Telescopic cylinders 21 are fixedly mounted on the front and rear sides of the roller bracket 1, and the piston rod end of the telescopic cylinder 21 is hinged to the sliding seat 16. Therefore, before or after placing the pipe, the sliding seat 16 can be moved along the guide slide rods 15 by controlling the length of the telescopic cylinder 21 according to the pipe diameter, weight, and process requirements. Since the second roller 3 is mounted on the sliding seat 16 via bearing seats, its position changes accordingly. This achieves dynamic adjustment of the center distance between the second roller 3 and the first roller 2, allowing the transmission belt 4 to be tightened or loosened. This provides sufficient positive pressure on the drive belt for pipes of different weights to generate the necessary frictional driving force and prevent slippage. At the same time, it avoids excessive tension leading to premature fatigue, or excessive looseness causing slippage, wear, and sagging between the drive belt and the rollers.

[0036] In Example 6, as a further preferred embodiment of Example 1, multiple support rollers 22 are rotatably connected to the bottom of the inner cavity of the roller bracket 1. These support rollers 22 are evenly distributed along the outer surface of the transmission belt 4, supporting the lower running section of the transmission belt 4 and preventing sagging deformation during operation. The rotation axes of the support rollers 22 are parallel to the first roller 2 and the second roller 3, and are perpendicular to the transmission direction. The multiple support rollers 22 form a continuous, flexible support platform on the return section (slack side) below the transmission belt 4, providing uniform upward support force to the transmission belt. This effectively eliminates sagging caused by the weight of the transmission belt 4 itself, long-term elongation due to use, and the pressure of the pipe weight. Simultaneously, the rolling contact between the multiple support rollers 22 and the lower surface of the transmission belt 4 transforms the original sliding friction into rolling friction, significantly reducing transmission resistance and energy consumption, and extending the service life of the transmission belt.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
