Description

Technical Field

[0001] This invention relates to the field of steel pipe conveying, and more particularly to an automated steel pipe conveying device. Background Technology

[0002] Steel pipes need to go through multiple processes during processing. During the process of going through different processes, the steel pipes need to be moved from the conveyor of one process to the conveyor of another process. During this process, they are usually carried by workers. However, steel pipes are very heavy, and manual handling consumes a lot of labor and is unsafe for workers, as it may result in workers being injured by falling pipes. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides an automated steel pipe conveying device.

[0004] The automated steel pipe conveying device provided in this application adopts the following technical solution: An automated steel pipe conveying device includes a first conveying mechanism and a second conveying mechanism that cooperate with two adjacent processes. The first conveying mechanism is the conveying mechanism for the previous process, and the second conveying mechanism is the conveying mechanism for the next process. The first conveying mechanism includes a first support frame, a first conveying platform, and a first trolley. The first support frame is arranged along the axial direction of the steel pipe. Multiple first conveying platforms are equidistantly arranged along the length direction of the first support frame. Each first conveying platform corresponds to a first trolley. The first trolley moves along the length direction of the first conveying platform through a first horizontal linear module. The second conveying mechanism includes a second support frame, a second conveying platform, and a second trolley. The second support frame is arranged along the axial direction of the steel pipe. Multiple second conveying platforms are equidistantly arranged along the length direction of the second support frame. Each second conveying platform corresponds to a second trolley. The second trolley moves along the length direction of the second conveying platform through a second horizontal linear module. A tilting plate is rotatably mounted on one end of the first conveyor table near the second conveyor table. The tilting plate includes a first plate and a second plate that are vertically connected. The first plate is positioned close to the first conveyor table. The first conveyor table near the second conveyor table has a first clearance groove and a second clearance groove for the tilting plate to make way when it rotates. The top wall of the second clearance groove is lower than the top wall of the first clearance groove. The rotating shaft of the tilting plate is rotatably connected to the first conveyor table through a support base. The support base is fixedly installed on the top wall of the second clearance groove. The rotating shaft is rotatably connected to the support base. The flipping plate has a first state and a second state. Before the steel pipe flips, the first plate of the flipping plate is horizontal and the side of the first plate away from the second plate abuts against the top wall of the first clearance groove. At this time, the flipping plate is in the first state. After the steel pipe flips, the second plate of the flipping plate is horizontal and the side of the second plate away from the first plate abuts against the top wall of the second clearance groove. At this time, the flipping plate is in the second state. When the flipping plate is in the first state, the top surface of the first plate is below the first trolley. When the flipping plate is in the second state, the top surface of the second trolley is below the second plate. A pusher cylinder is provided at the end of the first trolley away from the tilting plate, and the pusher cylinder pushes the steel pipe toward the direction closer to the tilting plate; The first conveyor table is equipped with a drive assembly for driving the tilting plate to tilt. A second limiting rod is provided at the end of the second plate away from the first plate. The second limiting rod is slid into the second receiving groove by the control component until it is completely located in the second receiving groove. The control component includes a metal sheet and an electromagnet used in conjunction. The metal sheet is connected to the side wall of the second limiting rod. A first mating groove is provided on the side of the second plate near the second clearance groove for the metal sheet to pass through. A second mating groove is provided on the inner wall of the second clearance groove. The electromagnet is fixed in the second mating groove and is energized. When the flipping plate rotates to the point where the second plate abuts against the top wall of the second clearance groove, the electromagnet is energized and magnetically attracts the metal sheet. The metal sheet passes into the second mating groove and drives the second limiting rod to slide towards the second receiving groove until it is completely located in the second receiving groove.

[0005] By adopting the above technical solution, the first trolley moves the steel pipe toward the direction of the flipping plate via the first horizontal linear module. When the first trolley moves close to the flipping plate, it stops moving, and the push cylinder pushes the steel pipe toward the direction of the flipping plate, causing the steel pipe to fall onto the flipping plate. Then, the drive assembly drives the flipping plate to rotate 90°, so that the side of the second plate away from the first plate abuts against the top wall of the second clearance groove. Then, the steel pipe rolls from the second plate onto the second trolley. The automation level is high, no workers are required to handle the pipe, reducing the labor and workload of workers, and improving the safety of steel pipe transportation, making it less likely to cause injury to workers.

[0006] Preferably, when the flip plate is in the first state, the top surface of the first plate body is inclined downward from the direction of approaching the first trolley to away from the first trolley, and when the flip plate is in the second state, the top surface of the second plate body is inclined downward from the direction of away from the second trolley to approach the second trolley.

[0007] By adopting the above technical solution, the inclined surface of the first plate facilitates the entry of the steel pipe into the flipping plate, and the inclined surface of the second plate facilitates the falling of the steel pipe onto the second trolley.

[0008] Preferably, a first baffle is provided at the end of the first trolley away from the push cylinder. The first baffle is rotatably connected to the first trolley via a torsion spring. The torsion spring applies a force to the first baffle, causing the first baffle to rotate in a direction away from the flip plate. When the push cylinder pushes the steel pipe to move in a direction closer to the flip plate, it overcomes the force of the torsion spring. At this time, the movement of the steel pipe causes the first baffle to rotate in a direction away from the push cylinder.

[0009] By adopting the above technical solution, the first baffle is designed to prevent the steel pipe from detaching from the first trolley.

[0010] Preferably, a second baffle is provided at both ends of the second trolley along its length, and the height of the second baffle does not prevent the steel pipe from falling from the flipping plate onto the second trolley.

[0011] By adopting the above technical solution, the second baffle is designed to prevent the steel pipe from detaching from the second trolley.

[0012] Preferably, the drive assembly includes a telescopic cylinder, a connecting rod, and a guide plate. The telescopic cylinder is fixedly installed on the side wall of the first conveyor table. The piston rod of the telescopic cylinder is hinged to one end of the connecting rod, and the other end of the connecting rod is slidably connected to the guide plate. The guide plate is fixedly connected to the rotating shaft of the tilting plate. A guide groove is provided on the guide plate, and the end of the connecting rod away from the telescopic cylinder slides in the guide groove.

[0013] By adopting the above technical solution, the piston rod of the telescopic cylinder is initially in the extended state. When driving the tilting plate to rotate, the piston rod of the telescopic cylinder pulls the end of the connecting rod away from the guide plate to move towards the direction of the first conveyor table. The end of the connecting rod that is slidably connected to the guide plate swings away from the first conveyor table, thereby driving the tilting plate to rotate.

[0014] Preferably, a set of drive components is provided on each side of the width direction of each of the first conveyor tables.

[0015] By adopting the above technical solution, the uniformity of stress on the steel pipe is improved, thereby enhancing the stability of the steel pipe in tipping over.

[0016] Preferably, a first limiting rod is provided at the end of the first plate away from the second plate. The first limiting rod is slidably connected to the first plate. The sliding direction of the first limiting rod is perpendicular to the length direction of the first plate. A first receiving groove is provided on the first plate for the first limiting rod to slide. A first telescopic spring is provided in the first receiving groove. One end of the first telescopic spring is fixedly connected to the inner bottom wall of the first receiving groove. The other end of the first telescopic spring is fixedly connected to the bottom end of the first limiting rod. The first telescopic spring applies a force to the first limiting rod to make the first limiting rod slide in the direction outside the first receiving groove. The side of the first limiting rod near the second plate is tangent to the outer peripheral wall of the steel pipe. The side of the first limiting rod away from the second plate is the first wedge surface. The end of the first wedge surface away from the first plate is closer to the steel pipe than the end of the first wedge surface near the first plate. When the steel pipe moves toward the direction of the flipping plate and passes the first wedge surface of the first limiting rod, the steel pipe pushes the first limiting rod toward the first receiving groove. The opening of the first receiving groove is provided with a first limiting chamfer that matches the first wedge surface to prevent the first limiting rod from disengaging from the first receiving groove.

[0017] Preferably, the second limiting rod is slidably connected to the second plate, the sliding direction of the second limiting rod is perpendicular to the length direction of the second plate, the second plate has a second receiving groove for the second limiting rod to slide, a second telescopic spring is provided in the second receiving groove, one end of the second telescopic spring is fixedly connected to the inner bottom wall of the second receiving groove, the other end of the second telescopic spring is fixedly connected to the bottom end of the second limiting rod, and the second telescopic spring applies a force to the second limiting rod to make the second limiting rod slide in the direction of the second receiving groove. The side of the second limiting rod closest to the first plate is tangent to the outer peripheral wall of the steel pipe, and the side of the second limiting rod away from the first plate is the second wedge surface. The end of the second wedge surface away from the second plate is closer to the steel pipe than the end of the second wedge surface close to the second plate. The opening of the second receiving groove is provided with a second limiting chamfer that matches the second wedge surface to prevent the second limiting rod from disengaging from the second receiving groove.

[0018] By adopting the above technical solution, the first and second limit rods limit the steel pipe, preventing it from detaching from the tilting plate during the tilting process, thus improving the safety of steel pipe transportation and preventing the steel pipe from falling and injuring workers.

[0019] Preferably, the top wall of the second clearance groove is provided with an installation groove, and a pressure sensor is provided in the installation groove. The top of the pressure sensor is flush with the top wall of the second clearance groove. When the flip plate rotates to the point where the second plate abuts against the top wall of the second clearance groove, the flip plate abuts against the pressure sensor. The pressure sensor is electrically connected to the electromagnet. When the flip plate abuts against the pressure sensor, the pressure sensor sends a contact signal to the control system of the electromagnet and controls the electromagnet to be energized. The control system of the electromagnet is equipped with a timing module, which is used to de-energize the electromagnet at regular intervals. The energization time of the electromagnet is set according to the time it takes for the steel pipe to fall from the second plate onto the second trolley. When the steel pipe falls onto the second trolley, the electromagnet is de-energized.

[0020] By adopting the above technical solution, when the flipping plate rotates to the point where the second plate body abuts against the top wall of the second clearance groove, the flipping plate abuts against the pressure sensor. The pressure sensor sends a contact signal to the control system of the electromagnet and controls the electromagnet to be energized. The electromagnet magnetically attracts the iron sheet, which penetrates into the second mating groove and drives the second limiting rod to slide towards the second receiving groove until it is completely located in the second receiving groove. At this time, the steel pipe loses the limitation of the second limiting rod and rolls along the inclined surface of the second plate body onto the second trolley.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. High degree of automation, no need for staff to handle materials, reducing the labor force and workload of staff; 2. Improved safety of steel pipe transportation, reducing the risk of injury to workers from falling pipes. Attached Figure Description

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses an automated steel pipe conveying device.

[0029] Reference Figure 1 The automated steel pipe conveying device includes a first conveying mechanism 1 and a second conveying mechanism 2 that cooperate with two adjacent processes. The first conveying mechanism 1 is the conveying mechanism for the previous process, and the second conveying mechanism 2 is the conveying mechanism for the next process.

[0030] Reference Figure 1 The first conveying mechanism 1 includes a first support frame 11, a first conveying platform 12 and a first trolley 13. The first support frame 11 is arranged along the axial direction of the steel pipe 9. Multiple first conveying platforms 12 are arranged at equal intervals along the length direction of the first support frame 11. Each first conveying platform 12 corresponds to a first trolley 13. The first trolley 13 moves along the length direction of the first conveying platform 12 through the first horizontal linear module 14.

[0031] Reference Figure 1 The second conveying mechanism 2 includes a second support frame 21, a second conveying platform 22, and a second trolley 23. The second support frame 21 is arranged along the axial direction of the steel pipe 9. Multiple second conveying platforms 22 are equidistantly arranged along the length direction of the second support frame 21. Each second conveying platform 22 corresponds to a second trolley 23. The second trolley 23 moves along the length direction of the second conveying platform 22 through the second horizontal linear module 24.

[0032] Reference Figures 1-3A flip plate 3 is rotatably mounted on one end of the first conveyor table 12 near the second conveyor table 22. The flip plate 3 includes a first plate 31 and a second plate 32 connected vertically. The first plate 31 is located near the first conveyor table 12. The first conveyor table 12 near the second conveyor table 22 has a first clearance groove 121 and a second clearance groove 122 for the flip plate 3 to make way when it rotates. The top wall of the second clearance groove 122 is lower than the top wall of the first clearance groove 121. The rotating shaft of the flip plate 3 is rotatably connected to the first conveyor table 12 through a support base 4. The support base 4 is fixedly installed on the top wall of the second clearance groove 122, and the rotating shaft is rotatably connected to the support base 4.

[0033] Reference Figures 1-3 The flip plate 3 has a first state and a second state. Before the steel pipe 9 flips, the first plate 31 of the flip plate 3 is horizontal and the side of the first plate 31 away from the second plate 32 abuts against the top wall of the first clearance groove 121. At this time, the flip plate 3 is in the first state. After the steel pipe 9 flips, the second plate 32 of the flip plate 3 is horizontal and the side of the second plate 32 away from the first plate 31 abuts against the top wall of the second clearance groove 122. At this time, the flip plate 3 is in the second state. When the flip plate 3 is in the first state, the top surface of the first plate 31 is below the first trolley 13. When the flip plate 3 is in the second state, the top surface of the second trolley 23 is below the second plate 32.

[0034] When the tilting plate 3 is in the first state, the top surface of the first plate 31 tilts downward from the direction close to the first trolley 13 to the direction far away from the first trolley 13, so as to facilitate the steel pipe 9 entering the tilting plate 3. When the tilting plate 3 is in the second state, the top surface of the second plate 32 tilts downward from the direction far away from the second trolley 23 to the direction close to the second trolley 23, so as to facilitate the steel pipe 9 falling onto the second trolley 23.

[0035] A push cylinder 131 is provided at the end of the first trolley 13 away from the tilting plate 3. The push cylinder 131 pushes the steel pipe 9 toward the tilting plate 3.

[0036] A first baffle 132 is provided at the end of the first trolley 13 away from the push cylinder 131. The first baffle 132 is rotatably connected to the first trolley 13 via a torsion spring. The torsion spring applies a force to the first baffle 132, causing the first baffle 132 to rotate in a direction away from the tilting plate 3, thus preventing the steel pipe 9 from detaching from the first trolley 13. When the push cylinder 131 pushes the steel pipe 9 to move in a direction closer to the tilting plate 3, it overcomes the force of the torsion spring. At this time, the movement of the steel pipe 9 causes the first baffle 132 to rotate in a direction away from the push cylinder 131.

[0037] The second trolley 23 is provided with second baffles 231 at both ends along its length. The height of the second baffles 231 does not prevent the steel pipe 9 from falling from the flip plate 3 onto the second trolley 23, thus preventing the steel pipe 9 from detaching from the second trolley 23.

[0038] Reference Figures 1-3 A drive assembly 5 for driving the tilting plate 3 to tilt is provided on the first conveyor table 12. The drive assembly 5 includes a telescopic cylinder 51, a connecting rod 52, and a guide plate 53. The telescopic cylinder 51 is fixedly installed on the side wall of the first conveyor table 12. The piston rod of the telescopic cylinder 51 is hinged to one end of the connecting rod 52, and the other end of the connecting rod 52 is slidably connected to the guide plate 53. The guide plate 53 is fixedly connected to the rotating shaft of the tilting plate 3, and a guide groove 531 is provided on the guide plate 53. The end of the connecting rod 52 away from the telescopic cylinder 51 slides in the guide groove 531. In the initial state, the piston rod of the telescopic cylinder 51 is in the extended state. When driving the tilting plate 3 to rotate, the piston rod of the telescopic cylinder 51 pulls the end of the connecting rod 52 away from the guide plate 53 towards the direction closer to the first conveyor table 12, and the end of the connecting rod 52 slidably connected to the guide plate 53 swings away from the first conveyor table 12, thereby driving the tilting plate 3 to rotate. Moreover, the driving force provided by the telescopic cylinder 51 is very stable, which makes the overall conveying device have a long service life.

[0039] Each first conveyor 12 has a set of drive components 5 on both sides in the width direction, which improves the uniformity of the force on the steel pipe 9, thereby improving the stability of the steel pipe 9 when tipping over.

[0040] Reference Figure 3 A first limiting rod 6 is provided at the end of the first plate 31 away from the second plate 32. The first limiting rod 6 is slidably connected to the first plate 31. The sliding direction of the first limiting rod 6 is perpendicular to the length direction of the first plate 31. A first receiving groove 311 is provided on the first plate 31 for the first limiting rod 6 to slide. A first telescopic spring 312 is provided in the first receiving groove 311. One end of the first telescopic spring 312 is fixedly connected to the inner bottom wall of the first receiving groove 311, and the other end of the first telescopic spring 312 is fixedly connected to the bottom end of the first limiting rod 6. The first telescopic spring 312 applies a force to the first limiting rod 6, causing the first limiting rod 6 to slide outward from the first receiving groove 311.

[0041] The side of the first limiting rod 6 closest to the second plate 32 is tangent to the outer peripheral wall of the steel pipe 9. The side of the first limiting rod 6 furthest from the second plate 32 is the first wedge surface 61. The end of the first wedge surface 61 furthest from the first plate 31 is closer to the steel pipe 9 than the end of the first wedge surface 61 closest to the first plate 31. When the steel pipe 9 moves toward the direction of the flipping plate 3 and passes the first wedge surface 61 of the first limiting rod 6, the steel pipe 9 pushes the first limiting rod 6 toward the first receiving groove 311.

[0042] The opening of the first receiving groove 311 is provided with a first limiting chamfer 3111 that cooperates with the first wedge surface 61 to prevent the first limiting rod 6 from disengaging from the first receiving groove 311.

[0043] ReferenceFigure 3 A second limiting rod 7 is provided at the end of the second plate 32 away from the first plate 31. The second limiting rod 7 is slidably connected to the second plate 32. The sliding direction of the second limiting rod 7 is perpendicular to the length direction of the second plate 32. A second receiving groove 321 is provided on the second plate 32 for the second limiting rod 7 to slide. A second telescopic spring 322 is provided in the second receiving groove 321. One end of the second telescopic spring 322 is fixedly connected to the inner bottom wall of the second receiving groove 321, and the other end of the second telescopic spring 322 is fixedly connected to the bottom end of the second limiting rod 7. The second telescopic spring 322 applies a force to the second limiting rod 7 to make the second limiting rod 7 slide in the direction of the second receiving groove 321.

[0044] The side of the second limiting rod 7 closest to the first plate 31 is tangent to the outer peripheral wall of the steel pipe 9. The side of the second limiting rod 7 furthest from the first plate 31 is the second wedge surface 71. The end of the second wedge surface 71 furthest from the second plate 32 is closer to the steel pipe 9 than the end of the second wedge surface 71 closest to the second plate 32.

[0045] The opening of the second receiving groove 321 is provided with a second limiting chamfer 3211 that cooperates with the second wedge surface 71 to prevent the second limiting rod 7 from disengaging from the second receiving groove 321.

[0046] The first limiting rod 6 and the second limiting rod 7 limit the steel pipe 9, preventing the steel pipe 9 from detaching from the tilting plate 3 during the tilting process, thus improving the safety of the steel pipe 9 during transportation and preventing the steel pipe 9 from falling and injuring the staff.

[0047] Reference Figure 4 The second limiting rod 7 slides into the second receiving groove 321 through the control component 8 until it is completely inside the second receiving groove 321. The control component 8 includes a metal sheet 81 and an electromagnet 82 used in conjunction. The metal sheet 81 is connected to the side wall of the second limiting rod 7. The second plate 32 has a first mating groove 323 on the side near the second relief groove 122 for the metal sheet 81 to pass through. The first mating groove 323 is connected to the second receiving groove 321. The inner wall of the second relief groove 122 has a second mating groove 1221. The electromagnet 82 is fixed in the second mating groove 1221 and is energized. The side wall of the first conveying table 12 has an electrical wire hole 83 that communicates with the second mating groove 1221. When the flip plate 3 rotates to the point where the second plate 32 abuts against the top wall of the second relief groove 122, the electromagnet 82 is energized and magnetically attracts the metal sheet 81. The metal sheet 81 overcomes the force of the second telescopic spring 322 and passes into the second mating groove 1221, driving the second limiting rod 7 to slide towards the second receiving groove 321 until it is completely located in the second receiving groove 321.

[0048] The top wall of the second clearance groove 122 is provided with an installation groove, and a pressure sensor 1222 is installed in the installation groove. The top of the pressure sensor 1222 is flush with the top wall of the second clearance groove 122. When the flip plate 3 rotates to the point where the second plate 32 abuts against the top wall of the second clearance groove 122, the flip plate 3 abuts against the pressure sensor 1222. The pressure sensor 1222 is electrically connected to the electromagnet 82. When the flip plate 3 abuts against the pressure sensor 1222, the pressure sensor 1222 sends a contact signal to the control system of the electromagnet 82 and controls the electromagnet 82 to be energized.

[0049] The control system of electromagnet 82 is equipped with a timing module. The timing module is used to de-energize electromagnet 82 at regular intervals. The energization time of electromagnet 82 is set according to the time it takes for steel pipe 9 to fall from the second plate 32 to the second trolley 23. When steel pipe 9 falls onto the second trolley 23, electromagnet 82 is de-energized.

[0050] When the flip plate 3 rotates to the point where the second plate 32 abuts against the top wall of the second clearance groove 122, the flip plate 3 abuts against the pressure sensor 1222. The pressure sensor 1222 sends a contact signal to the control system of the electromagnet 82 and controls the electromagnet 82 to be energized. The electromagnet 82 magnetically attracts the iron piece 81. The iron piece 81 passes into the second mating groove 1221 and drives the second limiting rod 7 to slide towards the second receiving groove 321 until it is completely located in the second receiving groove 321. At this time, the steel pipe 9 loses the limitation of the second limiting rod 7 and rolls along the inclined surface of the second plate 32 onto the second trolley 23.

[0051] The implementation principle of an automated steel pipe conveying device according to an embodiment of this application is as follows: The first trolley 13, driven by the first horizontal linear module 14, moves the steel pipe 9 toward the direction of approaching the flipping plate 3. When the first trolley 13 moves close to the flipping plate 3, it stops moving. The push cylinder 131 pushes the steel pipe 9 toward the direction of approaching the flipping plate 3. The movement of the steel pipe 9 causes the first baffle 132 to rotate away from the push cylinder 131. When the steel pipe 9 passes the first wedge surface 61 of the first limiting rod 6, it pushes the first limiting rod 6 toward the first receiving groove 311 until the steel pipe 9 continues to move and falls onto the flipping plate 3. Then, the drive assembly 5 drives the flipping plate 3 to rotate 90°, so that the side of the second plate 32 away from the first plate 31 abuts against the top wall of the second relief groove 122. When the flipping plate 3 rotates to the point where the second plate 32 abuts against the top wall of the second relief groove 122, the rotation continues. When the flip plate 3 comes into contact with the pressure sensor 1222, the pressure sensor 1222 sends a contact signal to the control system of the electromagnet 82 and controls the electromagnet 82 to be energized. The electromagnet 82 magnetically attracts the iron piece 81, and the iron piece 81 passes into the second mating groove 1221 and drives the second limiting rod 7 to slide into the second receiving groove 321 until it is completely located in the second receiving groove 321. At this time, the steel pipe 9 loses the limitation of the second limiting rod 7 and rolls along the inclined surface of the second plate 32 onto the second trolley 23. The second trolley 23 drives the steel pipe 9 to move away from the flip plate 3 through the second horizontal linear module 24. The whole process is highly automated, requires no manual handling, reduces the labor and workload of the staff, and improves the safety of the steel pipe 9 transportation, making it less likely to cause injury to the staff.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
