Description

Technical Field

[0001] This invention relates to the technical field of steel pipe forming, specifically to a high dynamic load roller conveyor suitable for steel pipe forming. Background Technology

[0002] Roller conveyors are the main equipment for transporting rolled products in steel rolling mills. Steel pipes also require roller conveyors for transport during production. Roller conveyor systems, which withstand high-intensity, high-frequency dynamic loads, must balance high precision, high durability, and environmental adaptability. For example, a steel pipe conveyor roller conveyor with announcement number CN206375271U includes a lifting frame, an active conveying device, and a driven conveying device. The lifting frame includes a base one, with a hydraulic cylinder at its center. Two supports are symmetrically arranged on the base one, and two support rods are mounted on each support. One end of each support rod is mounted on one of the supports, and the other end is rotatably connected via a connecting block on the telescopic rod of the hydraulic cylinder. The active conveying device includes a base two, with an active roller support on the base two, and an active roller mounted on the active roller support. The active roller is driven by a motor. The driven conveying device includes a base three, with a driven roller support on the base three, and a driven roller mounted on the driven roller support. This utility model uses a lifting frame to place steel pipes on a conveying device, which not only reduces the workload of workers but also prevents the steel pipes from violently impacting the conveying equipment during placement.

[0003] For example, a pipe-connecting device for a small-diameter steel pipe production line, with announcement number CN220949665U, consists of a V-shaped steel pipe conveying roller conveyor, a lifting steel pipe connecting roller conveyor, and an upper pressure roller. The lifting steel pipe connecting roller conveyor overlaps with the V-shaped steel pipe conveying roller conveyor and is positioned above the V-shaped steel pipe conveying roller conveyor. The upper pressure roller is positioned above the lifting steel pipe connecting roller conveyor. The lifting steel pipe connecting roller conveyor consists of a push-pull cylinder, a push-pull mechanism, and a roller support mechanism. The push-pull cylinder and roller support mechanism are both located on the V-shaped steel pipe conveying roller conveyor, and the push-pull mechanism connects the push-pull cylinder and the roller support mechanism. The structure is scientifically and rationally designed, offering advantages such as producing various specifications of steel pipes without frequent adjustments to the height of the steel pipe production line conveying roller conveyor, saving manpower and resources, high production efficiency, convenient assembly and connection, stable and reliable pipe-connecting conveying, and high transmission synchronization. It is a highly innovative pipe-connecting device for a small-diameter steel pipe production line. However, the above-mentioned steel pipe conveying roller conveyor still has the following disadvantages in actual use:

[0004] 1. Traditional steel pipe forming roller conveyors are not convenient to adjust the spacing of their load-bearing capacity. When conveying heavy pipes, it is necessary to increase the density of the roller conveyor to ensure stability, while when conveying light pipes, it is necessary to reduce the density of the roller conveyor to reduce production energy consumption.

[0005] 2. Furthermore, when roller conveyors transport pipes for extended periods, friction occurs between the pipes and the roller conveyors, causing varying degrees of wear on the roller conveyor surface. Replacing the roller conveyors is inconvenient and increases production costs. Therefore, there is a lack of structures that reduce the wear of the roller conveyors themselves.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing high dynamic load roller conveyor. Summary of the Invention

[0007] The purpose of this invention is to provide a high dynamic load roller conveyor suitable for steel pipe forming, so as to solve the problems mentioned in the background art that traditional steel pipe forming roller conveyors are inconvenient to adjust the load spacing during use and lack a structure to reduce the wear of the roller conveyor itself.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A high dynamic load roller conveyor suitable for steel pipe forming includes a support base, on the inner side of which first rollers and second rollers are alternately arranged, and two adjacent first rollers are driven by the same motor, and two adjacent second rollers are driven by another motor.

[0010] It also includes: a protective component disposed on the first roller, the protective component being used to improve the wear resistance of the first roller;

[0011] A cleaning mechanism is located at the front end of the support base. The cleaning mechanism is positioned between the first roller and the second roller at the front end, and the cleaning mechanism is driven by a pulley mechanism and a bevel gear set to drive the roller shaft of the first roller.

[0012] Preferably, the second roller is movably mounted on the inner side of the movable seat, and the movable seat is slidably disposed in the fixed groove, which is opened in the support seat. Meanwhile, a lead screw passes through the internal thread of the movable seat, and the bottom of the lead screw is driven by a motor. Through the thread transmission between the lead screw and the movable seat, the movable seat can be raised and lowered.

[0013] Preferably, a connecting block is fixed at the middle break of the first roller and the second roller, and magnetic blocks are arranged at equal angles on the outer side of the connecting block. The second roller and the support base form a relative lifting structure. The stability of the steel pipe during transportation can be improved by the adsorption of the magnetic blocks on the steel pipe.

[0014] Preferably, the protective component includes a protective steel sheet that is fitted to the outer surface of the first roller, and a connecting plate is fixed to the side of the protective steel sheet near the first roller. A fixing hole is reserved at the end of the connecting plate away from the protective steel sheet. The connecting plate slides through the side of the first roller. By fitting the connecting plate to the outside of the first roller, it can play a role in preventing wear.

[0015] Preferably, the first roller has an adjusting rod that rotates through it, and the adjusting rod and the connecting block are connected by damping rotation. A fixing plate is fixed to the outside of the adjusting rod, and a limit rod is fixed to the end of the fixing plate away from the adjusting rod. The adjusting rod rotates through the roller shaft of the first roller, and rotating the adjusting rod can drive the fixing plate to rotate, thereby driving the limit rod to connect or separate from the fixing hole.

[0016] Preferably, the limiting rod has an arc-shaped structure, and the center of the arc of the limiting rod coincides with the rotation center of the adjusting rod. The limiting rod and the fixing hole are engaged. At the same time, the protective steel plate, the connecting plate, the fixing plate and the limiting rod are all distributed at equal angles. When the limiting rod passes through the inside of the fixing hole, it can lock the connecting plate.

[0017] Preferably, the cleaning mechanism includes a fixed ring fixed to the inner side of the support base, and the side of the fixed ring is connected to an external suction device through an air supply pipe. The bottom of the fixed ring is fixed to the inner bottom surface of the support base through a support plate. Meanwhile, a movable ring is rotatably provided on the inner side of the fixed ring. The movable ring rotates inside the fixed ring to achieve comprehensive cleaning of the pipeline.

[0018] Preferably, the movable ring has a hollow structure, and the outer wall of the movable ring has an annular through groove. The movable ring is connected to the air supply pipe through the through groove. At the same time, the inner wall of the movable ring is provided with cleaning brushes and suction holes at equal angles, and impurities on the pipe can be transferred to the air supply pipe through the through groove.

[0019] Preferably, the outer wall of the movable ring is fixed with toothed blocks at equal angles, and the toothed blocks and gears are meshed together. The gear shaft is connected to the shaft of one of the first rollers through a bevel gear set and a pulley mechanism. The movable ring can be driven to rotate through the meshing transmission of the gear and the toothed blocks.

[0020] Compared with the prior art, the beneficial effects of the present invention are: this high-dynamic load roller conveyor suitable for steel pipe forming can adjust the density of the roller conveyor according to the weight of the conveyed pipe, thereby changing its density and adapting the load-bearing strength of the roller conveyor when conveying the pipe. Furthermore, it can clean impurities on the pipe during conveying and reduce wear on the roller conveyor caused by the pipe. The specific details are as follows:

[0021] 1. The second roller is driven to descend synchronously through the screw drive between the lead screw and the movable seat. At this time, only the first roller transports the pipeline, which can reduce production energy consumption. When the second roller is needed, it can be raised to be level with the first roller.

[0022] 2. The protective steel sheet passes through the first roller via the connecting plate. Rotating the adjusting rod drives the fixed plate to rotate, which in turn drives the limiting rod to pass through the fixed hole, thus locking the protective steel sheet onto the first roller and protecting it. When the protective steel sheet needs to be replaced, simply rotate the adjusting rod in the opposite direction to release the locking of the limiting rod onto the connecting plate.

[0023] 3. The meshing transmission of gears and toothed blocks drives the movable ring to rotate within the fixed ring, which in turn drives the cleaning brush to clean the surface of the pipe. The swept-off impurities are sucked into the movable ring through the suction hole and then discharged through the through groove, preventing impurities on the pipe from falling onto the rollers and other positions and affecting the smoothness of the conveying.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-11 The present invention provides the following technical solution:

[0038] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a high-dynamic load roller conveyor suitable for steel pipe forming, comprising a support base 1, with first rollers 2 and second rollers 3 alternately arranged on the inner side of the support base 1, and two adjacent first rollers 2 being driven by the same motor, and two adjacent second rollers 3 being driven by another motor; further comprising: a protective component disposed on the first roller 2, the protective component being used to improve the wear resistance of the first roller 2; and a cleaning mechanism disposed at the front end of the support base 1, the cleaning mechanism being disposed between the first roller 2 and the second roller 3 at the front end, and the cleaning mechanism being driven by the roller shaft of the first roller 2 through a pulley mechanism and a bevel gear set 24.

[0039] Existing steel pipe forming roller conveyors are inconvenient to adjust in terms of their load-bearing spacing. When conveying heavy pipes, the roller density needs to be increased to ensure stability, while when conveying lighter pipes, the roller density needs to be reduced to lower production energy consumption. Figures 1-5As shown, the second roller 3 is movably installed inside the movable seat 4, and the movable seat 4 is slidably disposed in the fixed groove 6, which is opened in the support seat 1. At the same time, the internal thread of the movable seat 4 is threaded through the lead screw 5, and the bottom of the lead screw 5 is driven by a motor. A connecting block 7 is fixed at the middle break of the first roller 2 and the second roller 3, and a magnetic block 8 is set at an equal angle on the outer side of the connecting block 7. The second roller 3 and the support seat 1 form a relative lifting structure. First, the pipe is conveyed on the first roller 2 and the second roller 3. When conveying a heavier pipe, the first roller 2 and the second roller 3 convey at the same time. When conveying a lighter pipe, the motor drives the lead screw 5 to rotate. Through the threaded transmission between the lead screw 5 and the movable seat 4, the movable seat 4 and the second roller 3 are driven to descend synchronously. At this time, only the first roller 2 conveys the pipe, which can reduce production energy consumption. When the second roller 3 is needed, it only needs to be raised to be level with the first roller 2.

[0040] Example 2: When roller conveyors transport pipes for extended periods, friction occurs between the pipes and the rollers, causing varying degrees of wear on the roller surface. Replacing the rollers is inconvenient and increases production costs. Therefore, there is a lack of structures to reduce roller wear. This example addresses this issue through the following technical solution: Figure 2 and Figures 9-11 As shown, the protective assembly includes a protective steel sheet 9 fitted to the outer surface of the first roller 2. A connecting plate 10 is fixed to the side of the protective steel sheet 9 closest to the first roller 2, and a fixing hole 11 is provided at the end of the connecting plate 10 away from the protective steel sheet 9. The connecting plate 10 slides through the side of the first roller 2. An adjusting rod 12 rotates through the inside of the first roller 2, and the adjusting rod 12 and the connecting block 7 are connected by damping rotation. A fixing plate 13 is fixed to the outside of the adjusting rod 12, and a limiting rod 14 is fixed to the end of the fixing plate 13 away from the adjusting rod 12. The adjusting rod 12 rotates through the roller shaft of the first roller 2. The limiting rod 14 has an arc-shaped structure, and the center of the arc of the limiting rod 14 coincides with the center of rotation of the adjusting rod 12. The limiting rod 14 and the fixing hole 11 are engaged. The protective steel sheet 9, connecting plate 10, fixing plate 13, and limiting rod 14 are all distributed at equal angles. By setting the protective steel sheet 9 on the outside of the first roller 2, wear of the first roller 2 during transport can be prevented. When the protective steel sheet 9 is worn, it can be directly replaced. The protective steel sheet 9 passes through the first roller 2 through the connecting plate 10. Then, rotating the adjusting rod 12 drives the fixing plate 13 to rotate synchronously. Then, the limiting rod 14 passes through the fixing hole 11 of the connecting plate 10, which can lock the protective steel sheet 9 on the first roller 2 to protect the first roller 2. When the protective steel sheet 9 needs to be replaced, the adjusting rod 12 is rotated in the opposite direction to release the locking of the limiting rod 14 on the connecting plate 10. When the first roller 2 rotates, it drives the adjusting rod 12 to rotate synchronously without affecting the rotation of the adjusting rod 12 in the roller shaft of the first roller 2.

[0041] Example 3: In existing roller conveyors, impurities on the pipeline fall onto the roller conveyor and surrounding equipment during transport, thus affecting the smoothness of the conveyor's operation. Furthermore, there is a lack of a structure to clean the pipeline during transport. Therefore, this example addresses this issue through the following technical solution: Figures 6-8 As shown, the cleaning mechanism includes a fixed ring 18 fixed to the inner side of the support base 1. The side of the fixed ring 18 is connected to an external suction device via an air supply pipe 20, and the bottom of the fixed ring 18 is fixed to the inner bottom surface of the support base 1 via a support plate 19. A movable ring 16 is rotatably mounted on the inner side of the fixed ring 18. The movable ring 16 has a hollow structure, and its outer wall has an annular through groove 23. The movable ring 16 is connected to the air supply pipe 20 via the through groove 23. A cleaning brush 21 and a suction hole 22 are provided at equal angles on the inner wall of the movable ring 16. A toothed block 17 is fixed at equal angles on the outer wall of the movable ring 16, and the toothed block 17 and the gear 15 are meshed. The axle of the gear 15... The pipe is connected to the roller shaft of one of the first rollers 2 via a bevel gear assembly 24 and a pulley mechanism. When the pipe starts to convey, it passes through the movable ring 16. At this time, the first roller 2 rotates, and its roller shaft drives the bevel gear assembly 24 to rotate via the pulley mechanism. Then it drives the gear 15 to rotate. Through the meshing transmission between the gear 15 and the tooth block 17, the movable ring 16 rotates within the fixed ring 18, which in turn drives the cleaning brush 21 to clean the surface of the pipe. After cleaning, the air pipe 20 is connected to the external air suction equipment, so that the swept-off impurities can be sucked into the movable ring 16 through the suction hole 22 and then discharged through the through groove 23, preventing impurities on the pipe from falling onto the rollers and other positions and affecting the smoothness of the conveying.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
