Description

Technical Field

[0001] The invention relates to the technical field of pipeline processing, in particular to an integrated processing device for steel pipe processing. Background Art

[0002] In the actual use of scaffolding steel pipes, they are often exposed to various conditions due to long-term exposure to the external environment. For example, the surface of the steel pipe is prone to rust, and in order to make the steel pipe better adapt to different construction scenarios and meet relevant quality and aesthetic standards, it is often necessary to grind and remove rust, spray paint, and spray at fixed distances and other complex treatments.

[0003] From the perspective of traditional processing mode, most of these tasks are completed manually. However, this manual operation method has many problems. In terms of efficiency, the speed of manual operation is very limited. Workers can only process one steel pipe at a time. Whether it is grinding and rust removal, painting or fixed-distance spraying, it takes a lot of time and energy. In terms of the labor intensity of workers, the grinding and rust removal process requires workers to hold grinding tools for a long time, which consumes a lot of physical strength of workers; during the painting process, workers have to constantly adjust the angle and position of the spray gun, and also ensure that the paint is evenly sprayed, which also requires a lot of physical strength. Therefore, the development of a steel pipe processing device that can automatically perform grinding, painting and fixed-distance spraying is of great significance to improving production efficiency, reducing the labor intensity of workers, improving the working environment, and ensuring the quality of processing.

[0022] Working principle: The processing chamber is fixed on the support frame to provide a closed space for grinding and rust removal. Servo motor 2 drives the bidirectional lead screw to rotate, so that the threaded ring moves synchronously in opposite directions on both sides of the outer wall of the bidirectional lead screw. The threaded ring is connected to the long rod through an extension plate to adjust the position of the long rod to adapt to steel pipes of different diameters. Telescopic rod 1 can adjust the length according to different specifications of steel pipes, drive the cross bar to move, and the rotating shaft in the cross bar enables the auxiliary rod to rotate freely to adapt to changes in the shape and position of the steel pipe. The roller frame on the auxiliary rod and the long rod on one side plays an auxiliary support and rolling role when the steel pipe is ground and rusted. The servo motor 1 on the auxiliary rod on the other side drives the driving wheel to rotate, and the grinding brush on the driving wheel grinds and rusts the surface of the steel pipe. Multiple driving wheels are connected by chains to ensure synchronous rotation. , to achieve comprehensive grinding and rust removal on the surface of the steel pipe, the servo motor drives the telescopic rod three, and the telescopic rod three is connected to the threaded short rod. When the threaded short rod rotates, due to the limiting effect of the long slide bar on the moving ring, the moving ring can only move left and right, and the moving ring moves to make the inclined rod squeeze the inclined plate, and the inclined plate rotates with the limiting ring as the fixed point, driving the support block to fit the inner wall of the steel pipe, and the ball inside the support block reduces the friction with the inner wall of the steel pipe. When the support block fits the inner wall of the steel pipe, the telescopic rod three contracts, driving the threaded short rod, moving ring, inclined rod, inclined plate and support block and other components to move, realizing steel pipe transmission, one end of the telescopic slide bar in the flipping assembly is connected to the long slide bar, and the other end is connected to the support block through the telescopic plate, the micro motor drives the friction plate to rotate, giving friction to the inner wall of the steel pipe to flip the steel pipe, and the roller The round rod slides in the circular groove of the limit ring to provide space for the steel pipe to rotate, so that the steel pipe can be turned over when clamped, so as to process the overall outer surface of the steel pipe. The guide rail is fixed on the support frame, and the slide slides on the guide rail. The paint sprayer on one side of the slide sprays the paint evenly on the surface of the steel pipe. The paint spraying pressure, flow rate and angle can be adjusted according to different painting requirements. There is a heating element inside the drying ring on the other side of the slide. The air pump sucks in the outside air and compresses it to transport it into the drying ring. The heating element generates high-temperature airflow to dry the paint on the surface of the steel pipe. The second telescopic rod drives the baffle to move back and forth in the drying ring to block the ventilation holes and change the drying width. The heating wire can change the temperature of the circulating gas inside the drying ring to carry out targeted drying of different types of paints. The sensing unit monitors the external environment of the processed steel pipe by configuring multiple sensors. The algorithm configuration unit configures adaptive algorithms for each mechanism. For example, the grinding and rust removal mechanism adopts the PID control algorithm to adjust the clamping force and motor speed according to the feedback data of the pressure sensor and displacement sensor; the automatic flip transmission unit adopts the fuzzy control algorithm to adjust the transmission speed and flip angle according to the feedback data of the speed sensor and position sensor; the paint spraying and drying unit adopts the neural network control algorithm to adjust the paint spraying amount and drying temperature according to the feedback data of the temperature sensor and humidity sensor; the fixed-distance spraying unit adopts the genetic algorithm to optimize the spraying distance and parameters according to the feedback data of the distance sensor, and the interactive unit monitors the working status, sensor data and control parameters of each unit.

[0023] The present invention provides an integrated processing device for steel pipe processing, which has the following beneficial effects:

[0024] 1. The present invention can adapt to steel pipes of different diameters through the grinding and rust removal mechanism to ensure comprehensive grinding. The paint spraying and drying mechanism can accurately adjust parameters to ensure uniform spraying and rapid drying of the paint. The fixed-distance spraying unit accurately controls the spraying distance. The coordination of various links makes the steel pipe processing quality stable and reliable, meeting high-standard production requirements.

[0025] 2. The present invention reduces costs and labor intensity, and the automated operation reduces labor costs and reduces the risk of work-related injuries. Metal scraps can be recycled to save resources, and algorithm control optimizes paint and energy consumption, reducing production costs. The coordinated work of various mechanisms reduces the tediousness of manual operations, reduces the labor intensity of workers, and improves the sustainability of production.

[0026] 3. The present invention improves production efficiency. The integrated equipment concentrates multiple processes, reduces the transfer time of steel pipes between different equipment, and each mechanism operates automatically and works in coordination, without the need for frequent manual intervention, which speeds up production. At the same time, the algorithm accurately controls each link to ensure efficient and stable operation, greatly improving the overall production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example:

[0038] Please see attached Figure 1 - Attachment Figure 8 , the embodiment of the present invention provides an integrated processing equipment for steel pipe processing, including a support frame 1, a grinding and rust removal mechanism, which is fixedly connected to one side of the outer wall of the support frame 1, and performs preliminary processing on the outer wall of the steel pipe;

[0043] The grinding and rust removal mechanism includes a processing chamber 2, which is fixedly connected to one side of the outer wall of the support frame 1, one side of the inner wall of the processing chamber 2 is fixedly connected to one end of a telescopic rod 3, the other end of the telescopic rod 3 is fixedly connected to a cross bar 4, the interior of the cross bar 4 is slidably connected to a rotating shaft 5, the interior of the rotating shaft 5 is fixedly connected to an auxiliary rod 6, a plurality of auxiliary rods 6 are connected by a long rod 7, the auxiliary rods 6 and the cross bar 4 are symmetrically arranged with the long rod 7 as the center, a roller frame 8 is fixedly connected to the outer wall of the auxiliary rod 6 on one side and a servo motor 9 is fixedly connected to one side of the outer wall of the auxiliary rod 6 on the other side. The output end of the lever 9 passes through the auxiliary rod 6 and is fixedly connected to one side of the outer wall of the driving wheel 10, and the other side of the outer wall of the driving wheel 10 is fixedly connected to a grinding brush 11. Multiple driving wheels 10 are connected by a chain 12. A servomotor 2 13 is fixedly connected to one side of the outer wall of the processing chamber 2. The output end of the servomotor 2 13 passes through the processing chamber 2 and is fixedly connected to a bidirectional lead screw 14. Both sides of the outer wall of the bidirectional lead screw 14 are threadedly connected to threaded rings 15. One end of an extension plate 16 is fixedly connected to one side of the outer wall of the threaded ring 15, and the other end of the extension plate 16 is fixedly connected to one side of the outer wall of the long rod 7.

[0044] Specifically, one end of a telescopic rod 3 is fixedly connected to one side of the inner wall of the processing bin 2. The telescopic rod 3 has good telescopic performance and can adjust the length according to steel pipes of different specifications, so that the cross bar 4 can be more flexibly adapted to steel pipes of different sizes for grinding and rust removal operations. The other end of the telescopic rod 3 is fixedly connected to a cross bar 4. The cross bar 4 provides a stable support structure for the installation and operation of subsequent components. The interior of the cross bar 4 is slidably connected to a rotating shaft 5. The design of the rotating shaft 5 enables the auxiliary rod 6 to rotate freely within a certain range, thereby better adapting to the shape and position changes of the steel pipe and improving the effect of grinding and rust removal. The interior of the rotating shaft 5 is fixedly connected to an auxiliary rod 6. Auxiliary rod 6, multiple auxiliary rods 6 are connected by long rod 7. This connection method enhances the stability of auxiliary rod 6, making it less likely to deform or shake during work. The auxiliary rod 6 and cross bar 4 are symmetrically arranged with the long rod 7 as the center, ensuring the balance and stability of the entire structure, making the grinding and rust removal process more uniform and efficient. The outer wall of the auxiliary rod 6 and the long rod 7 on one side is fixedly connected with a roller frame 8. The roller frame 8 can play an auxiliary support and rolling role when the steel pipe is ground and rusted, reduce the friction between the steel pipe and other components, and improve the transmission efficiency of the steel pipe and the quality of grinding and rust removal. The outer wall of the auxiliary rod 6 on the other side is fixedly connected with a servo motor The servo motor 9 has high-precision speed control and powerful power output, which can provide a stable power source for the rotation of the driving wheel 10. The output end of the servo motor 9 passes through the auxiliary rod 6 and is fixedly connected to one side of the outer wall of the driving wheel 10. The other side of the outer wall of the driving wheel 10 is fixedly connected to a grinding brush 11. The grinding brush 11 is made of high-quality wear-resistant material and can effectively remove rust and impurities on the surface of the steel pipe, thereby improving the surface quality of the steel pipe. Multiple driving wheels 10 are connected by a chain 12. The chain 12 transmission method has the characteristics of high transmission efficiency and good stability, which can ensure that multiple driving wheels 10 rotate synchronously, thereby achieving For comprehensive grinding and rust removal of the pipe surface, the design of the servo motor 13 driving the bidirectional lead screw 14 enables the threaded ring 15 to achieve synchronous reverse movement on both sides of its outer wall, thereby adjusting the position of the long rod 7 to adapt to grinding and rust removal operations on steel pipes of different diameters. Threaded rings 15 are threadedly connected to both sides of the outer wall of the bidirectional lead screw 14, and one end of an extension plate 16 is fixedly connected to one side of the outer wall of the threaded ring 15, and the other end of the extension plate 16 is fixedly connected to one side of the outer wall of the long rod 7. The extension plate 16 connects the threaded ring 15 and the long rod 7, converts the rotational motion of the bidirectional lead screw 14 into linear motion of the long rod 7, and realizes the width adjustment of the grinding and rust removal mechanism.

[0045] The automatic flipping mechanism includes a servo motor 17, which is fixedly connected to one side of the outer wall of the support frame 1, and the output end of the servo motor 17 is fixedly connected to one end of the telescopic rod 3 18, and the output end of the telescopic rod 3 18 is fixedly connected to one end of the threaded short rod 19, and the outer wall of the threaded short rod 19 is threadedly connected to a moving ring 20, and one side of the inner wall of the support frame 1 is fixedly connected to a limiting plate 21, and the inner part of the limiting plate 21 is slidably connected to a long slide bar 22, and one side of the outer wall of the moving ring 20 is fixedly connected to the long slide bar 22, and one side of the outer wall of the moving ring 20 is fixedly connected to one end of an inclined rod 23, and the other end of the inclined rod 23 is rotatably connected to a T-block 24, and the other end of the threaded short rod 19 is fixedly connected to a limiting ring 25, and one end of a slanted plate 26 is arranged inside the limiting ring 25, and the T-block 24 is slidably connected to the inside of the slanted plate 26, and the other end of the slanted plate 26 is rotatably connected to a support block 27, and the inner part of the support block 27 is slidably connected to a ball 28;

[0046] Specifically, under the rotation of the servo motor 17, the threaded short rod 19 rotates accordingly. Due to the limiting effect of the long slide bar 22 on the moving ring 20, the moving ring 20 can only move left and right along the axial direction of the threaded short rod 19. Under the moving effect of the moving ring 20, the inclined rod 23 gradually squeezes the inclined plate 26. After the inclined plate 26 is pushed by the inclined rod 23, it rotates with the limiting ring 25 as the fixed point. As the inclined plate 26 rotates, the support block 27 also adjusts its position accordingly and gradually fits the inner wall of the steel pipe. When the support block 27 is completely in contact with the inner wall of the steel pipe, the telescopic rod three 18 begins to shrink. The shrinking action of the telescopic rod three 18 drives the threaded short rod 19, the moving ring 20, the inclined rod 23, the inclined plate 26 and the support block 27 to move together, thereby realizing the transmission of the steel pipe. This transmission method is stable and reliable, and can ensure the smooth transmission of the steel pipe between various processing links, thereby improving the efficiency and quality of the entire processing process.

[0048] Specifically, the paint spraying and drying mechanism includes a guide rail 29, which provides a stable running track for the entire paint spraying and drying process. The guide rail 29 is made of high-strength material, has good wear resistance and corrosion resistance, and can ensure stable performance during long-term use. The slide 30 can slide smoothly on the guide rail 29 to achieve precise position adjustment. The slide 30 is manufactured using precision processing technology and has good accuracy and stability, which can ensure the accuracy of paint spraying and drying operations. The paint sprayer 31 is one of the core components of the paint spraying and drying mechanism, which can evenly spray paint on the surface of the steel pipe. The paint sprayer 31 adopts advanced spraying technology and has the advantages of uniform spraying, high efficiency, The paint sprayer 31 can be adjusted according to different painting needs, such as paint pressure, paint flow, paint angle, etc., to meet the painting requirements of steel pipes of different specifications. The drying ring 32 can quickly dry the steel pipe after spraying, thereby improving production efficiency. A heating element is arranged inside the drying ring 32, which can generate a high-temperature airflow to dry the paint on the surface of the steel pipe, ensuring that the heat is evenly distributed on the surface of the steel pipe to avoid local overheating or uneven drying. The input end of the air pump 33 is connected to the outside world, and can inhale fresh air, which is compressed and transported to the drying ring 32, and combined with the heat generated by the heating element to quickly dry the paint on the surface of the steel pipe.

[0049] The automatic flipping mechanism also includes a flipping assembly, which is arranged on one side of the outer wall of the long slide bar 22. The flipping assembly includes a telescopic slide bar 34, one end of the telescopic slide bar 34 is slidably connected to one side of the outer wall of the long slide bar 22, and the other end of the telescopic slide bar 34 is connected to the support block 27 through a telescopic plate 35. A micro motor 36 is fixedly connected to one side of the outer wall of the telescopic slide bar 34, and a friction plate 37 is fixedly connected to the output end of the micro motor 36.

One end of a round rod 40 is rotatably connected to one side of the outer wall of the roller 39, and the other end of the round rod 40 is fixedly connected to the inclined plate 26.

[0051] Specifically, the roller 39 and the round rod 40 slide inside the circular groove 38, and when the inside of the steel pipe is clamped, rotation space is provided for the steel pipe, so that the steel pipe can be flipped while being clamped, so as to grind, remove rust, spray paint and dry the entire outer surface of the steel pipe. The telescopic slide bar 34 moves up and down with the support block 27 and is parallel to the inner wall of the steel pipe. When the micro motor 36 is started, it can drive the friction plate 37 to rotate, give friction to the inner wall of the steel pipe, and make the steel pipe begin to flip.

[0052] One end of the telescopic rod 41 is fixedly connected to both sides of the inner wall of the drying ring 32, and the other end of the telescopic rod 41 is fixedly connected to the baffle 42. One side of the outer wall of the drying ring 32 is equidistantly provided with a plurality of ventilation holes 43;

[0053] The inner wall of the drying ring 32 is fixedly connected with a heating wire 44;

[0054] Specifically, the extension and retraction of the telescopic rod 41 can drive the baffle 42 to move back and forth inside the drying ring 32 to block the ventilation hole 43, thereby changing the drying width of the drying ring 32. Under the joint action of the heating wire 44, the temperature of the circulating gas inside the drying ring 32 can be changed, and different types of paints can be selectively dried in a targeted manner.

[0055] An empty slot 45 is provided at the bottom of the processing chamber 2 , and one side of the empty slot 45 is connected to a recovery chamber 46 .

[0056] Specifically, the metal scraps after grinding and rust removal on the outer wall of the steel pipe fall into the empty groove 45 and are collected and collected in the recovery bin 46, so that the metal scraps can be recycled.

[0057] The automated control system includes:

[0058] The sensing unit monitors the external environment of the processed steel pipe by configuring multiple sensors;

[0059] Algorithm configuration unit, which configures the appropriate algorithm for each institution and applies it;

[0060] Interactive unit,monitors the working status, sensor data and control parameters of each unit.

[0061] Specifically, during the grinding and rust removal process, it is necessary to accurately control the working force and speed of the grinding device and the rust removal device according to factors such as the material, diameter and surface condition of the steel pipe. The PID control algorithm is used to process the data fed back by the pressure sensor and the displacement sensor in real time to adjust the clamping force of the clamping mechanism and the motor speed of the grinding and rust removal device to achieve the best grinding and rust removal effect. When the pressure sensor detects that the clamping force of the clamping mechanism on the steel pipe is too large, the PID controller will reduce the motor current of the clamping mechanism and reduce the clamping force; when the displacement sensor detects that the working position of the grinding device deviates from the preset value, the PID controller will adjust the motor speed and direction of the grinding device to return it to the correct working position. The automatic flipping transmission unit needs to flexibly adjust the transmission speed and flipping angle according to the different specifications of the steel pipe to ensure that the steel pipe is smoothly transferred between each unit. A fuzzy control algorithm is used to automatically adjust the motor speed of the conveying mechanism and the flipping angle of the flipping mechanism according to the data fed back by the speed sensor and the position sensor, as well as the preset fuzzy rules. For example, when the speed sensor detects that the speed of the conveying mechanism is too fast, the fuzzy controller will reduce the motor speed of the conveying mechanism according to the preset fuzzy rules; when the position sensor detects that the position of the steel pipe in the flipping mechanism is inaccurate, the fuzzy controller will adjust the flipping angle of the flipping mechanism so that the steel pipe can accurately enter the next unit. The paint spraying and drying unit needs to accurately control the paint spraying amount and the operating temperature of the drying device according to different paint spraying process requirements and environmental conditions. The neural network control algorithm is adopted to learn and train the data fed back by the temperature sensor and humidity sensor, establish a nonlinear relationship model between the amount of paint sprayed and the drying temperature and the environmental conditions, and realize the precise control of the paint spraying device and the drying device. For example, when the temperature sensor detects that the working temperature of the drying device is too high, the neural network controller will automatically adjust the heating power of the drying device according to the learned model to reduce the working temperature; when the humidity sensor detects that the humidity of the painting environment is high, the neural network controller will adjust the amount of paint sprayed by the paint spraying device to ensure the quality of the paint spraying. The fixed-distance spraying unit needs to accurately adjust the distance between the spraying device and the steel pipe surface according to the different specifications of the steel pipe and the spraying requirements to ensure the accuracy of the fixed-distance spraying. The genetic algorithm is adopted to optimize the data fed back by the distance sensor to find the best spraying distance and spraying parameters. For example, the genetic algorithm first randomly generates a set of initial spraying distances and spraying parameters, and then calculates the fitness value of each individual according to the data fed back by the distance sensor. Through genetic operations such as selection, crossover and mutation, the spraying distance and spraying parameters are continuously optimized until the best solution is found.
