Description

Technical Field

[0001] The present application relates to the technical field of steel pipe transportation, and in particular to an auxiliary reversing structure for steel pipe processing and an application process thereof. Background Art

[0002] A steel pipe is a tubular object made of steel, commonly used as a pipeline for transporting fluids, such as oil, natural gas, water and coal gas. The production of steel pipes requires multiple processes such as cold drawing, cold rolling and hot rolling. During the processing of steel pipes, roller conveyors are usually used to transfer steel pipes in various processes.

[0003] In the steel pipe production workshop, various processing equipment will be arranged according to the direction of the conveyor used to transport the steel pipe, so the layout of the conveyor determines the floor space of the steel pipe production. In order to reduce the floor space of the steel pipe production line, the conveyors are usually installed vertically. Therefore, the steel pipe needs to change the transportation direction during transportation, that is, the steel pipe originally moves and is processed along the length direction of the first conveyor; after the steel pipe is processed, the steel pipe needs to turn 90 degrees on the spot and move along the width direction of the first conveyor to the second conveyor. The second conveyor transports the steel pipe to the next processing equipment for processing.

[0004] However, conventional reversing operations require manual changes in the direction of the steel pipe, and the steel pipe is kept at a high temperature during the processing. Therefore, the manual adjustment method cannot be used for a long time, which will eventually lead to low overall reversing efficiency when the processing part of the steel pipe needs to be changed, resulting in low transportation efficiency of the steel pipe, which is obviously insufficient. Summary of the invention

[0005] In order to improve the transportation efficiency of steel pipes, the present application provides an auxiliary reversing structure for steel pipe processing and an application process thereof.

[0006] The auxiliary reversing structure for steel pipe processing and its application process provided in this application adopt the following technical solutions: An auxiliary reversing structure for steel pipe processing includes a first conveyor and a second conveyor, the first conveyor and the second conveyor are vertically arranged, a reversing frame is provided at the connection point of the first conveyor and the second conveyor, a plurality of conveying rollers are rotatably connected to the reversing frame, a cylinder is rotatably connected to the reversing frame, the output shaft of the cylinder is provided with a receiving seat for carrying the steel pipe, a reversing assembly is provided on the reversing frame, the reversing assembly includes a first gear sleeved on the outer surface of the cylinder, the axis of the first gear is located at the intersection of the axes of the first conveyor and the second conveyor, a motor is provided on the reversing frame, the output shaft of the motor is provided with a second gear, and the second gear is meshed with the first gear.

[0007] By adopting the above technical solution, the first conveyor conveys the steel pipe to the receiving seat of the reversing frame. After the receiving seat receives the steel pipe, the cylinder starts to drive the receiving seat to move upward and lift the steel pipe. Then the motor starts to drive the second gear to rotate. The second gear rotates and drives the first gear to rotate 90°. The first gear drives the cylinder and the steel pipe to rotate together. After the reversal is completed, the cylinder drives the receiving seat to reset, and the receiving seat moves to a height flush with the second conveyor. At this time, the conveying roller on the reversing seat conveys the steel pipe to the second conveyor for continued transportation. This setting realizes automatic reversing of the steel pipe, effectively avoids the influence of adverse factors such as high temperature of the steel pipe on traditional manual reversing, and greatly improves the reversing efficiency of the steel pipe during the processing process.

[0008] Optionally, limit plates for limiting the steel pipe are slidably provided on the opposite sides of the first conveyor and the second conveyor, and a pulley is slidably provided on each limit plate along the length direction. The limit plates are provided with limit grooves for slidingly cooperating with the pulleys, and the pulleys are connected to the ends of the steel pipes through connecting components. Driving parts for driving the limit plates to move are provided on the first conveyor and the second conveyor.

[0009] By adopting the above technical scheme, when the steel pipe is transported on the first conveyor or the second conveyor, the driving member drives the limit plates on both sides to move toward each other and gradually approach the two end faces of the steel pipe. When the limit plates abut against the end faces of the steel pipe, the connecting assembly is started to connect the pulley to the steel pipe, and then the first conveyor or the second conveyor transports the steel pipe. The setting of the limit plates realizes the restriction of the steel pipe transportation path, effectively avoiding the axial deviation of the steel pipe during transportation. At the same time, the setting of the pulley and the connecting assembly prevents the steel pipe from axial movement or deviation during transportation, ensures that the axis of the steel pipe is perpendicular to the conveying direction, avoids the skewness of the steel pipe during transmission between the two limit plates, ensures that the steel pipe is accurately moved to the receiving seat, and provides a stable and reliable foundation for the subsequent reversing and transportation processes, thereby improving the stability and accuracy of the entire steel pipe transportation process.

[0010] Optionally, the connecting component includes a connecting block arranged on the pulley, a connecting sleeve is provided on the connecting block, a sliding block is provided on the connecting sleeve, a sliding groove for slidingly cooperating with the sliding block is opened on the connecting block, the connecting sleeve is made of magnetic material, an electromagnetic block is provided on the end surface of the connecting block away from the pulley, a magnetic ring for adsorbing the connecting sleeve is provided on the pulley, and the repulsive force generated by the electromagnetic block on the connecting sleeve is greater than the attractive force generated by the magnetic ring on the connecting sleeve.

[0011] By adopting the above technical scheme, when it is necessary to connect the steel pipe and the pulley, the electromagnetic block is energized, and the repulsive force generated by the energization of the electromagnetic block overcomes the attractive force of the magnetic ring on the connecting sleeve, pushing the connecting sleeve to slide outward along the sliding groove until it is inserted into the end of the steel pipe. At this time, the steel pipe is connected to the pulley under the insertion of the connecting sleeve, effectively preventing the steel pipe from detaching from the connecting sleeve during transportation, and avoiding the axial displacement of the steel pipe when it is transmitted between the two limit plates; when the steel pipe needs to be separated from the pulley, the electromagnetic block is powered off, at which time the repulsive force of the electromagnetic block on the connecting sleeve disappears, and the magnetic ring generates an adsorption force on the connecting sleeve, causing the connecting sleeve to slide along the sliding groove toward the pulley until the connecting sleeve is completely separated from the steel pipe. At this time, the connecting function of the connecting assembly disappears, allowing the steel pipe to smoothly enter the next processing or transportation link.

[0012] Optionally, an annular airbag is provided on the outer surface of the connecting sleeve, an inflation chamber is opened inside the pulley, the air outlet end of the inflation chamber is connected to the annular airbag through an air pipe, a piston block is slidably connected in the inflation chamber, and a push rod is provided at the end of the connecting sleeve close to the magnetic ring, the push rod extends into the inflation chamber and is arranged on the piston block.

[0013] By adopting the above technical solution, when the connecting sleeve slides toward the steel pipe under the action of electromagnetic force, the connecting sleeve drives the piston block to move in the inflation chamber through the push rod. At this time, the gas space inside the inflation chamber is reduced, and the gas inside the inflation chamber moves to the inside of the annular airbag through the air pipe. The annular airbag expands and fits tightly to the inner wall of the steel pipe; when the steel pipe needs to be separated from the pulley, the connecting sleeve moves toward the direction of the magnetic ring, the push rod moves in the opposite direction and pushes the piston block to move in the opposite direction. At this time, the gas space in the inflation chamber increases, and the gas in the annular airbag flows back to the inside of the inflation chamber through the air pipe, the annular airbag contracts, and the clamping force on the steel pipe is released, ensuring that the steel pipe and the pulley can be separated smoothly; the setting of the annular airbag fills the gap between the steel pipe and the connecting sleeve, thereby making the connection between the steel pipe and the connecting sleeve more stable. At the same time, the annular airbag can effectively absorb the collision force received by the steel pipe during transportation, and reduce the deformation or damage of the end of the steel pipe caused by collision.

[0014] Optionally, the socket is V-shaped, a negative pressure chamber is provided inside the socket, an air suction hole connected to the negative pressure chamber is provided on the surface of the socket, an air cylinder is provided on the reversing frame, an air outlet pipe of the air cylinder is connected to the negative pressure chamber through a bellows, a piston rod is slidably connected inside the air cylinder, and the end of the piston rod extending out of the air cylinder is provided on the output shaft of the cylinder through a connecting plate.

[0015] By adopting the above technical solution, before changing direction, the cylinder drives the receiving seat to rise, and at the same time, the cylinder drives the piston rod to move inside the air cylinder through the connecting plate. At this time, the gas space inside the air cylinder increases. Since the air cylinder is connected to the negative pressure chamber through the bellows, the air inside the negative pressure chamber enters the air cylinder through the bellows. The negative pressure chamber forms a negative pressure adsorption force on the surface of the receiving seat through the suction hole, thereby firmly adsorbing the steel pipe on the receiving seat. This arrangement realizes the fixation of the steel pipe before it rotates, prevents the steel pipe from being displaced or slipping due to inertia or other external forces during the changing direction process, and ensures that the axis of the steel pipe remains unchanged during the rotation, thereby ensuring the smooth transportation of the steel pipe on the second conveyor.

[0016] Optionally, a plurality of ejection holes are provided on the bottom surface of the receiving seat and the inner surface away from the second conveyor, and the plurality of ejection holes are connected to the negative pressure chamber. An elastic bag is provided at the end of each ejection hole. When the air cylinder inflates the negative pressure chamber, the elastic bag expands and abuts against the outer surface of the steel pipe.

[0017] By adopting the above technical scheme, after reversing, the cylinder drives the receiving seat to descend, and the cylinder drives the piston rod to move in the opposite direction in the air cylinder through the connecting plate. At this time, the gas space in the air cylinder is reduced, and the gas in the air cylinder is transmitted to the negative pressure chamber through the bellows. At this time, the gas in the negative pressure chamber flows into the suction hole and the ejection hole, and the suction hole generates a pushing airflow for the steel pipe. At the same time, the airflow flowing into the ejection hole makes the elastic belt inflated and expanded. Since the elastic bag is arranged on the bottom surface of the receiving seat and the inner surface away from the second conveyor, the elastic bag generates a component force toward the direction of the second conveyor during the expansion process. The component force pushes the steel pipe to move in the direction of the second conveyor, so that the steel pipe automatically detaches from the receiving seat after reversing. Such a setting realizes the automatic pushing of the steel pipe after reversing, improves the automation and continuity of the steel pipe transportation process, effectively reduces the jamming or delay that may be caused by the transfer link, thereby further improving the transportation efficiency of the steel pipe.

[0018] Optionally, an annular groove is provided on the inner side wall of the ejection hole, and a rubber ring plug-fitted with the annular groove is provided on the outer surface of the elastic band. In a natural state, the rubber ring has an interference fit with the inner side wall of the annular groove.

[0019] By adopting the above technical solution, when the air cylinder is inflated and the elastic bag begins to expand, the stability of the elastic bag in the connecting ring is maintained by the plug-in cooperation between the rubber ring and the ring groove, ensuring that the elastic bag will not detach from the ejection hole during the expansion process, thereby ensuring that the expanded elastic bag generates a stable thrust on the steel pipe toward the second conveyor.

[0020] An application process of an auxiliary reversing structure for steel pipe processing comprises the following steps in sequence: S1: The first conveyor transports the steel pipe: the steel pipe is placed on the first conveyor, and the driving member drives the limit plates on both sides to move towards each other and close to the two end surfaces of the steel pipe. When the limit plates abut against the end surfaces of the steel pipe, the connecting assembly connects the steel pipe and the pulley, and the first conveyor is started for transportation; S2: The receiving seat receives the steel pipe: when the steel pipe moves to the end of the first conveyor, the connection function of the connecting assembly is cancelled, and the first conveyor moves the steel pipe to the receiving seat; S3: Reversing assembly reversing steel pipe: After the receiving seat receives the steel pipe, the cylinder drives the receiving seat to move upward and lift the steel pipe, then starts the motor, the motor drives the second gear to rotate, the second gear drives the first gear to rotate 90°, the first gear drives the cylinder and the steel pipe to rotate together, completing the reversal; S4: The second conveyor transports the steel pipe: After the reversal is completed, the cylinder drives the receiving seat to reset, and the receiving seat moves to a height flush with the second conveyor. The conveying roller conveys the steel pipe to the second conveyor, and the driving member drives the limit plates on both sides to move toward each other and close to the two end surfaces of the steel pipe. When the limit plates abut the end surfaces of the steel pipe, the connecting assembly connects the steel pipe and the pulley, and the second conveyor is started to continue transportation.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. The embodiment of the present application sets a reversing assembly. When the receiving seat receives the steel pipe, the cylinder starts to drive the receiving seat to move upward and lift the steel pipe. Then the motor drives the second gear to rotate. The second gear rotates and drives the first gear to rotate 90 degrees. The first gear drives the cylinder and the steel pipe to rotate together. After the reversal is completed, the cylinder drives the receiving seat to reset. Such a setting realizes the automatic reversal of the steel pipe, effectively avoids the influence of adverse factors such as high temperature of the steel pipe on the traditional manual reversal, greatly improves the reversing efficiency of the steel pipe during the processing, and thus improves the efficiency of steel pipe transportation; 2. The present application sets a negative pressure chamber and an air suction hole. Before the reversal, the cylinder drives the negative pressure chamber to form a negative pressure state through the connecting plate. The negative pressure chamber forms a negative pressure adsorption force on the surface of the receiving seat through the air suction hole, thereby firmly adsorbing the steel pipe on the receiving seat. This setting realizes the fixation of the steel pipe before the steel pipe rotates, preventing the steel pipe from being displaced or slipping due to inertia or other external forces during the reversal process, ensuring that the axis of the steel pipe remains unchanged during the rotation process, thereby ensuring the smooth transportation of the steel pipe on the second conveyor; 3. In the present application, an ejection hole and an elastic bag are provided. After reversing, the cylinder drives the negative pressure chamber to form a positive pressure state through the connecting plate, and the negative pressure chamber ejects the elastic bag through the ejection hole. Since the elastic bag is arranged on the bottom surface of the receiving seat and the inner surface away from the second conveyor, the elastic bag generates a component force toward the second conveyor during the expansion process. The component force pushes the steel pipe to move toward the second conveyor, so that the steel pipe automatically detaches from the receiving seat after reversing. Such a setting realizes the automatic pushing of the steel pipe after reversing, improves the degree of automation and continuity of the steel pipe transportation process, effectively reduces the jamming or delay that may occur in the transfer link, and further improves the transportation efficiency of the steel pipe.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-7 This application is described in further detail.

[0031] The embodiments of the present application disclose an auxiliary reversing structure for steel pipe processing and an application process thereof.

[0032] Example 1 Reference Figure 1 An auxiliary reversing structure for steel pipe processing includes a first conveyor 01 and a second conveyor 02. The transmission directions of the first conveyor 01 and the second conveyor 02 are perpendicular to each other. The first conveyor 01 and the second conveyor 02 are both roller conveyors. The transportation method of the roller conveyor to transport the steel pipe 03 is an existing technology and will not be repeated here.

[0033] Reference Figure 1 and Figure 2 A reversing frame 1 is provided at the connection point between the first conveyor 01 and the second conveyor 02, and a conveying roller 101 for conveying the steel pipe 03 is rotatably connected to the reversing frame 1, and the conveying roller 101 is evenly arranged along the length direction of the second conveyor 02. A cylinder 102 is rotatably connected to the reversing seat, and the output shaft of the cylinder 102 is fixedly connected to a receiving seat 2 for carrying the steel pipe 03, and the cross-section of the receiving seat 2 is V-shaped. A reversing component 3 is provided on the reversing frame 1, and the reversing component 3 includes a first gear 31 fixedly sleeved on the outer surface of the cylinder 102, and the axis of the first gear 31 is located at the intersection of the axes of the first conveyor 01 and the second conveyor 02. A motor 32 is fixedly installed on the reversing frame 1, and the output shaft of the motor 32 is coaxially fixedly connected to the second gear 33, and the second gear 33 is meshed with the first gear 31.

[0034] The steel pipe 03 is transferred from the previous processing equipment to the first conveyor 01. The first conveyor 01 conveys the steel pipe 03 to the receiving seat 2 of the reversing frame 1. After the receiving seat 2 receives the steel pipe 03, the cylinder 102 starts to drive the receiving seat 2 to move upward and lift the steel pipe 03. Then the motor 32 starts and drives the second gear 33 to rotate. The second gear 33 rotates and drives the first gear 31 to rotate 90°. The first gear 31 drives the cylinder 102 and the steel pipe 03 to rotate 90° together. The axis of the steel pipe 03 changes from being perpendicular to the axis of the first conveyor 01 to being perpendicular to the axis of the first conveyor 01. The state is reversed to a parallel state. After the reversing is completed, the cylinder 102 drives the receiving seat 2 to descend, and the receiving seat 2 moves to a height flush with the second conveyor 02. At this time, the conveying roller 101 on the reversing seat conveys the steel pipe 03 to the second conveyor 02 for continued transportation, and the second conveyor 02 transports the steel pipe 03 to the next processing equipment. This setting realizes the automatic reversing of the steel pipe 03, effectively avoids the influence of adverse factors such as the high temperature of the steel pipe 03 on the traditional manual reversing, and greatly improves the reversing efficiency of the steel pipe 03 during the processing process.

[0035] Reference Figure 2 and Figure 3The surfaces opposite to the top wall of the receiving seat 2 are provided with guiding arc surfaces (not shown in the figure). Under the guidance of the guiding arc surfaces, the steel pipe 03 is conveniently transferred from the first conveyor 01, the receiving seat 2 and the second conveyor 02.

[0036] Reference Figure 2 , Figure 3 and Figure 4 A negative pressure chamber 4 is provided inside the receiving seat 2, and an air suction hole 41 connected to the negative pressure chamber 4 is provided on the surface of the receiving seat 2. An air cylinder 5 is fixedly installed on the reversing frame 1, and the air outlet end of the air cylinder 5 is connected to the inside of the negative pressure chamber 4 through a bellows 42. The air outlet end of the air cylinder 5 is arranged close to the bottom surface of the reversing frame 1, and the air cylinder 5 is slidably connected with a piston rod 51 along the length direction. The piston part of the piston rod 51 is tightly fitted with the inner wall of the air cylinder 5, and the end of the piston rod 51 extends out of the end of the air cylinder 5 away from the air outlet, and the output shaft of the cylinder 102 is fixedly connected with a connecting plate 1021, and the end of the connecting plate 1021 away from the cylinder 102 is fixedly connected to the end of the piston rod 51.

[0037] Before changing direction, the cylinder 102 drives the receiving seat 2 to rise, and at the same time, the cylinder 102 drives the piston rod 51 to move inside the air cylinder 5 through the connecting plate 1021. At this time, the gas space inside the air cylinder 5 increases. Since the air cylinder 5 is connected to the negative pressure chamber 4 through the bellows 42, the air inside the negative pressure chamber 4 enters the air cylinder 5 through the bellows 42. At this time, the negative pressure chamber 4 forms a negative pressure adsorption force on the surface of the receiving seat 2 through the suction hole 41, thereby firmly adsorbing the steel pipe 03 on the receiving seat 2, thereby achieving the fixation of the steel pipe 03 before the steel pipe 03 rotates, preventing the steel pipe 03 from being displaced or slipping due to inertia or other external forces during the changing direction process, ensuring that the axis of the steel pipe 03 remains unchanged during the rotation, thereby ensuring the smooth transportation of the steel pipe 03 on the second conveyor 02.

[0038] Reference Figure 2 , Figure 3 and Figure 4 A plurality of ejection holes 43 are provided on the bottom surface of the receiving seat 2 and the inner surface away from the second conveyor 02. The plurality of ejection holes 43 are connected to the negative pressure chamber 4. An elastic bag 6 is provided on the inner side wall of each ejection hole 4. In the present embodiment, the elastic belt is made of rubber material. When the air cylinder 5 inflates the negative pressure chamber 4, the elastic bag 6 expands and abuts against the outer surface of the steel pipe 03.

[0039] Reference Figure 2 , Figure 3 and Figure 4A ring groove 431 is provided on the inner wall of each ejection hole 43, and a rubber ring 61 is inserted and matched inside the ring groove 431. When the rubber ring 61 is in a natural state, the rubber ring 61 and the inner wall of the ring groove 431 have an interference fit, and the elastic bag 6 is fixedly connected to the rubber ring 61. When the air cylinder 5 is inflated to make the elastic bag 6 begin to expand, the elastic bag 6 is kept stable in the connecting ring by the insertion and matching of the rubber ring 61 and the ring groove 431, ensuring that the elastic bag 6 will not be separated from the ejection hole 43 during the expansion process.

[0040] After the reversal is completed, the cylinder 102 drives the receiving seat 2 to descend. During the descent of the receiving seat 2, the cylinder 102 drives the piston rod 51 to move toward the direction close to the air outlet end of the cylinder 5. At this time, the gas space in the cylinder 5 is reduced, and the gas in the cylinder 5 is transmitted to the negative pressure chamber 4 through the bellows 42. The gas in the negative pressure chamber 4 flows into the suction hole 41 and the ejection hole 43. The gas flowing into the suction hole 41 generates a pushing airflow for the steel pipe 03. Since the suction holes 41 are provided on the opposite inner walls of the receiving seat 2, the pushing airflows in the horizontal direction offset each other. The airflow flowing into the ejection hole 43 makes the elastic bag 6 inflate. It is placed on the bottom surface of the receiving seat 2 and away from the inner surface of the second conveyor 02. Therefore, the elastic bag 6 generates a component force toward the second conveyor 02 during the expansion process. The component force pushes the steel pipe 03 to move toward the second conveyor 02. At the same time, the elastic bag 6 on the bottom and the pushing airflow push the steel pipe 03 to move upward. At this time, under the push of the elastic bag 6 and the pushing airflow at the bottom, the steel pipe 03 can be smoothly transferred to the conveying roller 101 through the guide slope, thereby realizing the automatic pushing of the steel pipe 03 after the reversal, effectively reducing the jam or delay that may be caused by the transfer link, thereby further improving the transportation efficiency of the steel pipe 03.

[0041] Reference Figure 5 and Figure 6 , the first conveyor 01 and the second conveyor 02 are both slidably provided with limit plates 7 for limiting the steel pipe 03 on both opposite sides, the length direction of the limit plates 7 is parallel to the length direction of the first conveyor 01 or the second conveyor 02, the two limit plates 7 located on the first conveyor 01 are symmetrical about the axis of the first conveyor 01, the two limit plates 7 located on the second conveyor 02 are symmetrical about the axis of the second conveyor 02, the two limit plates 7 are symmetrical about the axis of the conveyors, and a limit groove 71 is provided on the side wall of each limit plate 7, the length direction of the limit groove 71 is parallel to the length direction of the limit plate 7, a pulley 8 is slidably connected in the limit groove 71, and the pulley 8 is connected to the end of the steel pipe 03 through a connecting assembly 9, and a driving member 10 for driving the limit plate 7 to move is fixedly connected to the first conveyor 01 and the second conveyor 02. In this embodiment, the driving member 10 is a plurality of driving cylinders 102, and the output shafts of the plurality of driving cylinders 102 are fixedly connected to the limit plate 7.

[0042] Reference Figure 6 and Figure 7 The connecting assembly 9 includes a connecting block 91 fixedly connected to the surface of the pulley 8 facing the steel pipe 03, a connecting sleeve 92 is provided on the outer surface of the connecting block 91, and the connecting sleeve 92 is a central sleeve. Two sliding blocks 921 are fixedly connected to the end of the connecting sleeve 92 facing the pulley 8. The two sliding blocks 921 are arranged opposite to each other. A sliding groove 911 that slides with the sliding block 921 is provided on the opposite outer side walls of the connecting block 91. The length direction of the sliding groove 911 is parallel to the axial direction of the connecting block 91. The connecting sleeve 92 is made of a magnetic material. In this embodiment, the connecting sleeve 92 is made of iron. An electromagnetic block 93 is fixedly connected to the end surface of the connecting block 91 away from the pulley 8, and a magnetic ring 94 for adsorbing the connecting sleeve 92 is fixedly connected to the end surface of the pulley 8 facing the connecting block 91. The magnetic ring 94 is sleeved on the outer surface of the connecting block 91. When the electromagnetic block is energized, the repulsive force generated by the electromagnetic block 93 on the connecting sleeve 92 is greater than the attractive force generated by the magnetic ring 94 on the connecting sleeve 92.

[0043] When the steel pipe 03 is transported to the first conveyor 01 or the second conveyor 02, the driving member 10 drives the limiting plates 7 on both sides to move toward each other until they abut against the two end surfaces of the steel pipe 03. At this time, under the limitation of the two limiting plates 7, the steel pipe 03 can only be transported along the area between the two limiting plates 7; After the limit plate 7 is adjusted, the electromagnetic block 93 is energized, and the repulsive force generated by the electromagnetic block 93 overcomes the attractive force of the magnetic ring 94 on the connecting sleeve 92. The electromagnetic block 93 pushes the connecting sleeve 92 to slide outward along the sliding groove 911 until it is inserted into the end of the steel pipe 03. At this time, the steel pipe 03 is connected to the pulley 8 under the insertion of the connecting sleeve 92, which effectively prevents the steel pipe 03 from being separated from the connecting sleeve 92 during transportation, avoids axial movement or deviation of the steel pipe 03 when it is transmitted between the two limit plates 7, ensures that the axis of the steel pipe 03 is perpendicular to the conveying direction, and avoids the skew of the steel pipe 03 when it is transmitted between the two limit plates 7; When the steel pipe 03 needs to be separated from the pulley 8, the electromagnetic block 93 is powered off. At this time, the repulsive force of the electromagnetic block 93 on the connecting sleeve 92 disappears, and the magnetic ring 94 generates an adsorption force on the connecting sleeve 92, causing the connecting sleeve 92 to slide along the sliding groove 911 toward the pulley 8 until the connecting sleeve 92 is completely separated from the steel pipe 03. At this time, the connecting function of the connecting assembly 9 disappears, allowing the steel pipe 03 to smoothly enter the next processing or transportation link.

[0044] Reference Figure 6 and Figure 7An annular airbag 11 is fixedly installed on the outer surface of the connecting sleeve 92, and the annular airbag 11 is sleeved on the end of the connecting sleeve 92 away from the connecting block 91. An inflation chamber 12 is opened inside the pulley 8, and a piston block 13 is slidably connected inside the inflation chamber 12. The outer surface of the piston block 13 is tightly fitted with the inner side wall of the inflation chamber 12. A plurality of push rods 14 are fixedly installed on the end surface of the connecting sleeve 92 close to the pulley 8. One end of the push rod 14 passes through the magnetic ring 94 and the side wall of the slider and extends to the inside of the inflation chamber 12. The end of the push rod 14 is fixedly connected to the piston block 13. A plurality of air pipes 15 for connecting the inflation chamber 12 and the annular airbag 11 are fixedly installed on the outer surface of the pulley 8.

[0045] When the connecting sleeve 92 moves toward the steel pipe 03 under the repulsive force of the electromagnetic block 93, the movement of the connecting sleeve 92 drives the push rod 14 to move, and the push rod 14 drives the piston block 13 to move inside the inflation chamber 12. At this time, the gas space inside the inflation chamber 12 is reduced, and the gas inside the inflation chamber 12 moves to the inside of the annular airbag 11 through the air pipe 15. The annular airbag 11 expands and fits tightly to the end of the steel pipe 03; when the steel pipe 03 needs to be separated from the pulley 8, the connecting sleeve 92 moves toward the pulley 8, the push rod 14 drives the piston block 13 to move in the opposite direction, and the inflation chamber 12 The gas space inside increases, and the gas in the annular airbag 11 flows back to the inflation chamber 12 through the air pipe 15. The annular airbag 11 contracts, releasing the clamping force on the steel pipe 03, ensuring that the steel pipe 03 and the pulley 8 can be separated smoothly; the setting of the annular airbag 11 fills the gap between the steel pipe 03 and the connecting sleeve 92, thereby making the connection between the steel pipe 03 and the connecting sleeve 92 more stable. At the same time, the annular airbag 11 can effectively absorb the collision force exerted on the steel pipe 03 during transportation, thereby reducing the deformation or damage of the end of the steel pipe 03 caused by collision.

[0046] The implementation principle of Example 1 is as follows: the steel pipe 03 is transferred from the previous processing equipment to the first conveyor 01, the first conveyor 01 conveys the steel pipe 03 to the receiving seat 2 of the reversing frame 1, after the receiving seat 2 receives the steel pipe 03, the cylinder 102 is started to drive the receiving seat 2 to move upward and lift the steel pipe 03, then the motor 32 is started and drives the second gear 33 to rotate, the second gear 33 rotates and drives the first gear 31 to rotate 90°, the first gear 31 drives the cylinder 102 and the steel pipe 03 to rotate 90° together, and the axis of the steel pipe 03 is perpendicular to the first conveyor. The state of the 01 axis is reversed to a parallel state. After the reversal is completed, the cylinder 102 drives the receiving seat 2 to descend, and the receiving seat 2 moves to a height flush with the second conveyor 02. At this time, the conveying roller 101 on the reversing seat conveys the steel pipe 03 to the second conveyor 02 for continued transportation, and the second conveyor 02 transports the steel pipe 03 to the next processing equipment. This setting realizes automatic reversing of the steel pipe 03, effectively avoids the influence of adverse factors such as high temperature of the steel pipe 03 on traditional manual reversing, and greatly improves the reversing efficiency of the steel pipe 03 during the processing process.

When the limit plates 7 abut against the end faces of the steel pipe 03, the electromagnetic block 93 is energized, and the electromagnetic block 93 pushes the connecting sleeve 92 to insert into the end of the steel pipe 03. The connecting sleeve 92 moves through the push rod 14 to drive the piston block 13 to move. The piston block 13 pushes the gas inside the inflation chamber 12 into the annular airbag 11, and the annular airbag 11 is inflated and abuts against the inner wall of the steel pipe 03, and then the first conveyor 01 is started for transportation; S2: The receiving seat receives the steel pipe: When the steel pipe 03 moves to the end of the first conveyor 01, the electromagnetic block 93 is powered off, the repulsive force of the electromagnetic block 93 on the connecting sleeve 92 disappears, the magnetic ring 94 attracts the connecting sleeve 92 to separate from the steel pipe 03, the connecting sleeve 92 moves through the push rod 14 to drive the piston block 13 to move in the opposite direction, the gas in the annular airbag 11 flows back to the inside of the inflation chamber 12 through the air pipe 15, the annular airbag 11 contracts, and the holding force on the steel pipe 03 is released, and the first conveyor 01 moves the steel pipe 03 to the receiving seat 2; S3: Reversing assembly reversing steel pipe: After the receiving seat 2 receives the steel pipe 03, the cylinder 102 drives the receiving seat 2 to move upward and lift the steel pipe 03. The cylinder 102 starts to drive the piston rod 51 to move inside the air cylinder 5. Negative pressure is formed inside the air cylinder 5 and the negative pressure chamber 4. The suction hole 41 fixes the steel pipe 03 on the receiving seat 2. Then the motor 32 is started. The motor 32 drives the second gear 33 to rotate. The second gear 33 drives the first gear 31 to rotate 90°. The first gear 31 drives the cylinder 102 and the steel pipe 03 to rotate together to complete the reversal. S4: The second conveyor transports the steel pipe: After the reversal is completed, the cylinder 102 drives the receiving seat 2 to reset, the piston rod 51 moves in the opposite direction inside the air cylinder 5, and the gas in the air cylinder 5 is transferred to the suction hole 41 and the ejection hole 43 through the bellows 42. The elastic bag 6 is inflated and pushes the steel pipe 03 to separate from the receiving seat 2. The conveying roller 101 conveys the steel pipe 03 to the second conveyor 02, and the driving member 10 drives the limiting plates 7 on both sides to move toward each other and close to the two end surfaces of the steel pipe 03. When the limiting plates 7 abut the end surfaces of the steel pipe 03, the connecting assembly 9 connects the steel pipe 03 and the pulley 8, and the second conveyor 02 is started to continue transportation.
