Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing support technology, and in particular to an auxiliary fixing device for steel pipe conveying. Background Technology

[0002] In the production, processing and logistics of steel pipes, steel pipes usually need to be transferred over long distances or between processes via roller conveyors, conveyor belts or cantilevered transmission lines. Due to the characteristics of steel pipes such as large length, heavy weight, high rigidity and easy rolling, problems such as lateral deviation and vibration are prone to occur during transportation. Especially in processing operations or loading and unloading, effective intermediate support and positioning are required to prevent steel pipes from colliding with other equipment and causing damage to the pipe surface or equipment, thereby ensuring processing accuracy and operational safety.

[0003] Currently, most common auxiliary support devices for steel pipe conveying adopt fixed arc brackets or simple roller supports. They are simple in structure and low in cost, but they generally have defects such as poor adaptability and inability to adjust. Most support structures are fixedly installed and their positions cannot be adjusted, making it difficult to adapt to steel pipes of different lengths and specifications. When changing the pipe material, it is often necessary to manually dismantle, reposition and fix the support components, which is cumbersome and time-consuming, and cannot meet the needs of modern automated production lines for rapid changeover and continuous and stable operation.

[0004] Therefore, there is an urgent need to provide an auxiliary fixing device for steel pipe conveying that can automatically adjust the support spacing according to the length of the steel pipe. Utility Model Content

[0005] In order to overcome the shortcomings of existing steel pipe conveying auxiliary support devices, such as poor adaptability, inconvenient adjustment, and inability to adjust their position after fixed installation, making it difficult to adapt to steel pipes of different lengths and specifications and meet the requirements of modern automated production lines for rapid changeover and continuous and stable operation, this utility model provides a steel pipe conveying auxiliary fixing device that can automatically adjust the support spacing according to the length of the steel pipe.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a steel pipe conveying auxiliary fixing device, comprising a guide seat, a guide rail structure located in the middle of the guide seat, two lower supports slidably mounted on the guide rail structure, an upper limit plate hinged to the top of each lower support via a hinged structure, mounting plates fixedly connected to both sides of the guide seat, a guide rod fixedly connected between the mounting plates, and two unidirectional screws arranged parallel to the guide rod rotatably mounted between the mounting plates, a dual-axis motor mounted on the guide seat, the output shafts at both ends of the dual-axis motor being fixedly connected to the corresponding unidirectional screws via couplings, and sliders fixedly connected to both sides of the lower supports, wherein one slider has a through hole matching the guide rod, forming a sliding connection with the guide rod, and the other slider has a threaded hole matching the unidirectional screw, forming a threaded connection with the unidirectional screw.

[0007] Preferably, mounting holes are provided at all four corners of the guide seat.

[0008] Preferably, the inner surfaces of both the lower support and the upper positioning plate are designed with an arc-shaped structure that matches the outer diameter of the steel pipe.

[0009] Preferably, the lower support is provided with a fixing frame at its lower part, and air tanks are installed on both sides of the fixing frame. An air pump is installed on the air tank, and the air inlet of the air pump is connected to the air tank. Airbags are provided inside the arc-shaped structure of the lower support and the upper limit plate. The upper airbag is connected to the air outlet of the nearby air pump through a first connecting pipe, while the lower airbag is connected to the air outlet of the nearby air pump through a second connecting pipe.

[0010] Preferably, a mounting frame is fixedly connected to the lower part of the lower support, a conveyor wheel is rotatably mounted on the mounting frame, a servo motor is provided on the side of the mounting frame, and the output shaft of the servo motor is fixedly connected to the drive shaft of the conveyor wheel by a key connection.

[0011] Preferably, the outer surface of the conveyor wheel has several anti-slip stripes evenly distributed along the axial direction.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting a dual-axis motor to drive two unidirectional screws with opposite rotation directions to rotate synchronously, the symmetrically arranged lower supports move towards or away from each other along the guide rail structure, thereby realizing automatic adjustment of the support width. This structure can quickly adapt to steel pipes of different lengths without manual disassembly or replacement of parts, which significantly improves the versatility and production efficiency of the device.

[0013] 2. The support surfaces of both the lower bracket and the upper limit plate are designed with an arc-shaped structure and are equipped with inflatable airbags. When the airbags are inflated, they can adaptively fit the surface of steel pipes with different outer diameters, achieving a flexible wrapping clamp with uniform force, avoiding surface damage such as indentations and scratches caused by rigid contact, and effectively protecting the quality of the pipes.

[0014] 3. By integrating a conveyor wheel structure at the bottom of the lower support, driven by a servo motor and with an anti-slip stripe design, the steel pipe can be directly pushed back and forth in the supported state, realizing integrated operation of support, positioning and conveying, reducing reliance on external power equipment and simplifying production line layout.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] Example 1: Please refer to Figures 1-3A steel pipe conveying auxiliary fixing device includes a guide seat 1. Mounting holes are provided at all four corners of the guide seat 1 to facilitate fixing the device to the ground or a support frame using bolts or other fasteners. A guide rail structure is provided in the middle of the guide seat 1, on which two symmetrically distributed lower supports 2 are slidably mounted. Each lower support 2 has an upper limit plate 3 hinged to its top via a hinge structure. The upper limit plate 3 can rotate around the hinge point to achieve its opening and closing action. Furthermore, the inner surfaces of the lower supports 2 and the upper limit plate 3 are designed with an arc-shaped structure matching the outer diameter of the steel pipe to increase the contact area, improve support stability, and prevent damage to the pipe surface. Mounting plates 4 are fixed to both sides of the guide seat 1, and guide rods 5 are fixedly connected between the mounting plates 4, allowing them to rotate together. The system is equipped with two unidirectional screws 6 arranged parallel to the guide rod 5. The two screws are designed with opposite rotation directions to ensure that they can drive the symmetrically arranged lower bracket 2 to move synchronously towards or away from each other when rotating synchronously. A dual-axis motor 7 is installed on the guide seat 1. The output shafts at the left and right ends of the dual-axis motor 7 are fixedly connected to the corresponding unidirectional screws 6 through couplings. Slider blocks 8 are fixedly connected to both the front and rear sides of the lower bracket 2. The slider 8 on the rear side has a through hole that matches the guide rod 5 and forms a sliding connection with the guide rod 5 to achieve the guiding and supporting functions. The slider 8 on the front side has a threaded hole that matches the unidirectional screw 6 and forms a threaded connection with the unidirectional screw 6. The forward or reverse rotation of the dual-axis motor 7 can control the rotation of the screws, thereby converting the rotational motion into the linear movement of the lower bracket 2.

[0023] When this device is in operation, the dual-axis motor 7 is first started according to the length of the steel pipe to be transported. The motor drives two unidirectional screws 6 with opposite directions of rotation to rotate synchronously. Since the front slider 8 is threadedly connected to the screws, and the lower support 2 is constrained by the guide rod 5 and the guide rail and cannot rotate, the two lower supports 2 move synchronously in opposite directions on the guide rail under the action of screw transmission, thereby adjusting their support spacing to accommodate steel pipes of different lengths. When the two lower supports 2 are adjusted to the appropriate position, the dual-axis motor 7 is turned off and the adjustment is stopped. Then, the upper limit plate 3 is opened upward around the hinge point, and the steel pipe is placed in the arc-shaped contact of the lower support 2. The upper limit plate 3 is then closed, and the steel pipe is firmly clamped by the pressing or locking mechanism. In this way, during the steel pipe transportation process, this device can effectively prevent the steel pipe from shifting laterally, provide reliable intermediate support and positioning, and improve the stability and safety of the transportation process.

[0024] Example 2: Based on Example 1, please refer to... Figure 4The lower support 2 is provided with a fixing frame 9 at its lower part. The fixing frame 9 is equipped with air tanks 10 on both the front and rear sides. An air pump 13 is installed on the air tank 10. The air inlet of the air pump 13 is connected to the air tank 10. The air tank 10 is used to store compressed gas and provide a stable air source for the inflation and deflation of the airbag 14. The lower support 2 and the upper limit plate 3 are both provided with airbags 14 inside their arc-shaped structures. The upper airbag 14 is connected to the air outlet of the air pump 13 on the front side through a first connecting pipe 11, while the lower airbag 14 is connected to the air outlet of the air pump 13 on the rear side through a second connecting pipe 12.

[0025] When the steel pipe is placed within the arc-shaped contact of the lower support 2 and the upper limit plate 3 is closed, the air pumps 13 on the front and rear sides are activated. The air pumps 13 draw compressed gas from their respective connected air tanks 10 and inflate the upper airbag 14 and lower airbag 14 through the first connecting pipe 11 and the second connecting pipe 12, respectively. As the gas is injected, the two airbags 14 expand synchronously, squeezing the outer wall of the steel pipe radially inward and filling the gap between the steel pipe and the arc-shaped structure. This achieves adaptive flexible wrapping clamping for steel pipes of different outer diameters. After the airbags 14 expand, they can conform to the surface of steel pipes of different diameters, significantly improving the compatibility of the device with various pipe diameter specifications. There is no need to replace the support structure. Furthermore, the flexible interface formed after inflation significantly reduces the sliding friction coefficient between the steel pipe and the support structure, preventing surface wear of the steel pipe due to friction during axial transportation.

[0026] Please see Figure 5 The lower support 2 is fixedly connected to the lower part of the mounting bracket 15. The mounting bracket 15 is rotatably mounted on the mounting bracket 15. The outer surface of the mounting bracket 16 has several anti-slip stripes evenly distributed along the axial direction to increase the friction coefficient between the mounting bracket 16 and the outer wall of the steel pipe, prevent slippage, and ensure stable and reliable transmission of driving force during start-up, acceleration and deceleration. The mounting bracket 15 is equipped with a servo motor 17 at the front. The output shaft of the servo motor 17 is fixedly connected to the drive shaft of the mounting bracket 16 by a key connection.

[0027] After the steel pipe is supported between the lower support 2 and the upper limit plate 3, if it is necessary to realize the axial left and right conveying of the steel pipe, the servo motor 17 is started. The servo motor 17 rotates forward or reverse according to the command. Its output shaft transmits torque to the conveying wheel 16 through a key connection, driving it to rotate synchronously. When the conveying wheel 16 rotates, the anti-slip stripes on its outer surface contact the outer wall of the steel pipe. Axial driving force is generated through a combination of rolling friction and local micro-sliding, which pushes the steel pipe to move smoothly in the predetermined direction, thereby realizing the integrated function of support and controllable conveying.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
