Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing, in particular to a conveying roller for steel pipe production and processing. Background Art

[0002] Steel pipe is a steel material with a hollow cross-section and its length is much longer than its diameter or circumference. During the production and processing of seamless steel pipes, due to the long length of the steel pipe as a whole, manual transportation is inconvenient. Therefore, the use of conveyor rollers can promptly transport the steel pipe to the location of the next processing, facilitating the processing of seamless steel pipes.

[0003] When steel pipes are transported using traditional conveyor rollers, the rollers can stably transport the steel pipes. However, in actual use, rollers of the same size cannot adjust and limit steel pipes of different sizes, affecting the efficiency of steel pipe transportation.

[0004] In order to overcome the above-mentioned defects, the existing technology (Chinese patent with publication number CN218490705U and announcement date of 2023-02-17) is a steel pipe conveying roller. A bidirectional threaded rod is installed inside the frame, and the two support seats are driven to adjust the distance under the action of the connecting block, so that the rollers inside the support seats can be adjusted in distance, so that it can be suitable for the transportation of steel pipes of different sizes, improve its applicability and reduce its limitations. By opening a first limit groove and a second limit groove on the bottom plate, in conjunction with the use of a limit block, two identical rollers can be combined together without the staff spending a lot of time on adjustment, thereby improving the efficiency of the combination and reducing the fatigue of the staff.

[0005] The above-mentioned mechanism adjusts the position between the two sleeves by using a bidirectional threaded rod, and then adjusts the spacing between the sleeves. However, in actual use, it is not convenient to use the bidirectional threaded rod to adjust the position during transportation and use, and it is not convenient to adapt and adjust in time according to the different conditions of the steel pipe. Manual control of the spacing is required in time, otherwise it will cause deviations in the transportation of the steel pipe. Utility Model Content

[0006] The purpose of the utility model is to provide a steel pipe production and processing conveying roller table to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned object, the utility model provides the following technical solution: a conveyor roller for steel pipe production and processing, comprising a conveyor box, one end of which is fixedly connected to a drive motor via a coupling, and a conveyor roller body rotatably connected to both sides of one end of the conveyor box, and both ends of the conveyor roller body are connected to the output end of the drive motor via a pulley;

[0008] A guide rod is provided at the middle position of one end between the conveying boxes, and an adjustment mechanism for adaptively adjusting steel pipes of different sizes is sleeved on the outer side of the guide rod, and the adjustment mechanism includes a left limiting wheel, and the left limiting wheel is sleeved on the outer side of the guide rod, and a right limiting wheel is sleeved on the other side of the outer side of the guide rod, and one side of the right limiting wheel is fixedly connected to the adjusting rod, and one side of the adjusting rod extends to the inner side of the left limiting wheel, and the adjusting rod and the left limiting wheel are in sliding connection;

[0009] The output end of the driving motor is connected to a cam via a pulley, and the cam is rotatably connected to one side of one end of the conveying box. Both ends of one side of the conveying box are provided with self-lubricating mechanisms for lubricating both ends of the conveying roller body.

[0010] Furthermore, a connecting spring is wound around the outer side of the guide rod, and an elastic structure is formed between the left limiting wheel, the right limiting wheel and the conveying box through the connecting spring.

[0011] Furthermore, a cleaning mechanism for cleaning the steel pipe is installed inside the conveying box through a connecting plate. The cleaning mechanism includes a mounting box, and the mounting box is mounted inside the conveying box through a connecting plate. A cleaning brush is connected to the inside of the mounting box through a spring.

[0012] Furthermore, one side of the left limiting wheel and the right limiting wheel are fixedly connected to a mounting rod, both sides of the interior of the conveying box are fixedly connected to airbags, and one side of the mounting rod is connected to the airbag, and one side of the airbag is connected to the mounting box through a hose.

[0013] Furthermore, return springs are provided at both ends of one side of the airbag, and one side of the return spring is connected to the interior of the conveying box.

[0014] Furthermore, the self-lubricating mechanism includes a fixed rod, and the fixed rod is fixedly connected to both sides of one end of the outside of the conveying box, the interior of the fixed rod is connected to an extension rod through a spring, and one side of the interior of the fixed rod is fixedly connected to an oil storage capsule, one side of the oil storage capsule is provided with an elastic sheet, and the elastic sheet is fixedly connected to the inside of the fixed rod, one side of the oil storage capsule is fixedly connected to a nozzle, and one side of the nozzle passes through and extends to the outside of the conveying box.

[0015] Furthermore, the cross section of the conveyor roller body is V-shaped, and the conveyor roller body is symmetrical about the vertical center axis of the conveyor box:

[0016] 1. The left and right limiting wheels are squeezed and pushed between each other by the weight of the steel pipe itself, so that the left and right limiting wheels are separated by the adjustment rod. At the same time, the left and right limiting wheels move to both sides along the direction of the guide rod, and the elastic force of the connecting spring applies an extrusion force in the opposite direction to the left and right limiting wheels, so that the left and right limiting wheels can adapt to steel pipes of different sizes while squeezing and clamping the steel pipe on one side between the left and right limiting wheels, avoiding the need to manually adjust the positions of the left and right limiting wheels;

[0017] Furthermore, when the left and right limiting wheels are squeezed to both sides by the steel pipe, the mounting rods on one side of the left and right limiting wheels will squeeze the airbags, and the gas inside the airbags will be transported to the inside of the mounting box through the hose. The gas inside the mounting box increases, pushing the cleaning brushes out and making contact with the steel pipe. The two sets of cleaning brushes can be used to clean different positions of the steel pipe.

[0018] Furthermore, a spring is provided inside the installation box. When the cleaning brush is pushed out, the length of the spring is extended. When the airbag stops being squeezed, the cleaning brush is reset by the spring force and the gas is squeezed back into the airbag, which is convenient for subsequent repeated use and cleaning of the surface of the steel pipe. In addition, a reset spring provided on one side of the airbag can play an auxiliary role in the reset of the airbag, thereby increasing the efficiency of the airbag reset.

[0019] 2. The conveying roller body is driven by a driving motor to convey the steel pipe. When the conveying roller body works for a long time, the connection between the pulley and the conveying roller body may become stuck due to insufficient lubrication, affecting the conveying efficiency of the steel pipe. The driving motor drives the cam to rotate during rotation, and uses the rotation of the cam to squeeze the extension rod, so that the extension rod can squeeze the elastic sheet inside the fixed rod, thereby deforming the elastic sheet and squeezing the oil storage capsule. After the oil storage capsule is squeezed, the lubricating oil is discharged through the nozzle, thereby achieving lubrication of the connection between the pulley and the conveying roller body. Since the fixed rod and the extension rod are connected by a spring, the extension rod will automatically reset when not pushed by the cam and perform repeated self-lubrication operations driven by the driving motor.

[0020] Furthermore, due to the elasticity of the elastic sheet, the elastic sheet will automatically reset to shield the oil storage capsule when it is not squeezed by the extension rod, thereby preventing the oil storage capsule from being squeezed all the time and causing the lubricating oil to drip.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figure 1-Figure 3 The technical solution shown is to solve the problem that the conveyor roller body 3 is not easy to adapt to seamless steel pipes of different sizes and the seamless steel pipe cannot be self-adapted to the limit size during transportation: the steel pipe production and processing conveyor roller table discloses an adjustment mechanism, including a conveyor box 1, one end of the conveyor box 1 is fixedly connected to the drive motor 2 through a coupling, and the conveyor roller body 3 is rotatably connected to both sides of one end of the conveyor box 1, and the two ends of the conveyor roller body 3 are connected to the output end of the drive motor 2 through a pulley;

[0031] A guide rod 10 is provided at the middle position of one end between the conveying boxes 1, and the outer side of the guide rod 10 is provided with an adjustment mechanism for adapting to steel pipes of different sizes. The adjustment mechanism includes a left limiting wheel 12, and the left limiting wheel 12 is sleeved on the outside of the guide rod 10.

[0032] A connecting spring 11 is wound around the outer side of the guide rod 10 , and an elastic structure is formed between the left limiting wheel 12 , the right limiting wheel 13 and the conveying box 1 through the connecting spring 11 .

[0033] In this example, by placing the seamless steel pipe to be transported in the middle position of the conveyor roller body 3, the weight of the steel pipe itself is used to squeeze and push between the left limiting wheel 12 and the right limiting wheel 13, so that the left limiting wheel 12 and the right limiting wheel 13 are separated by the adjusting rod 14. At the same time, the left limiting wheel 12 and the right limiting wheel 13 move to both sides along the direction of the guide rod 10, and the elastic force of the connecting spring 11 applies an extrusion force in the opposite direction to the left limiting wheel 12 and the right limiting wheel 13, so that the left limiting wheel 12 and the right limiting wheel 13 are separated. While adapting to steel pipes of different sizes, it can squeeze and clamp the steel pipe on one side between the left limiting wheel 12 and the right limiting wheel 13, avoiding the need to manually adjust the positions of the left limiting wheel 12 and the right limiting wheel 13. When processing steel pipes of different sizes, the left limiting wheel 12 and the right limiting wheel 13 can be squeezed and pushed to both sides by the gravity of the steel pipe. A connecting spring 11 is wound around the outer side of the guide rod 10, and an elastic structure is formed between the left limiting wheel 12, the right limiting wheel 13 and the conveying box 1 through the connecting spring 11.

[0034] Example 2:

[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The technical solution shown is based on the first embodiment and is intended to solve the problem of dust and impurities on the surface of seamless steel pipes during transportation: the steel pipe production and processing conveyor roller discloses a cleaning mechanism, and a cleaning mechanism for cleaning the steel pipes is installed inside the conveying box 1 through a connecting plate. The cleaning mechanism includes a mounting box 18, and the mounting box 18 is mounted inside the conveying box 1 through a connecting plate. A cleaning brush 19 is connected to the inside of the mounting box 18 through a spring.

[0036] One side of the left limiting wheel 12 and the right limiting wheel 13 are fixedly connected to the mounting rod 15, and both sides of the interior of the conveying box 1 are fixedly connected to the airbag 16, and one side of the mounting rod 15 is connected to the airbag 16, and one side of the airbag 16 is connected to the mounting box 18 through a hose;

[0037] Return springs 17 are provided at both ends of one side of the air bag 16 , and one side of the return spring 17 is connected to the interior of the conveying box 1 .

[0038] In this example, when the left limiting wheel 12 and the right limiting wheel 13 are squeezed to both sides by the steel pipe, the mounting rod 15 on one side of the left limiting wheel 12 and the right limiting wheel 13 will squeeze the airbag 16, and the gas inside the airbag 16 is transported to the inside of the mounting box 18 through the hose. The gas inside the mounting box 18 increases, pushing out the cleaning brush 19 and making contact with the steel pipe. Two sets of cleaning brushes 19 can be used to clean different positions of the steel pipe. At the same time, a spring is provided inside the mounting box 18. When the cleaning brush 19 is pushed out, the length of the spring is extended. When the airbag 16 stops being squeezed, the cleaning brush 19 is reset by the spring force and squeezes the gas back into the inside of the airbag 16, which is convenient for subsequent repeated use and cleaning of the surface of the steel pipe.

[0039] Example 3:

[0040] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The technical solution shown is to prevent the bearings of the conveying roller body 3 from becoming dry and stuck and unable to self-lubricate during long-term conveying: the steel pipe production and processing conveying roller table discloses an automatic lubrication mechanism, the output end of the driving motor 2 is connected to the cam 4 through a pulley, and the cam 4 is rotatably connected to one side of one end of the conveying box 1, and both ends of one side of the conveying box 1 are provided with a self-lubricating mechanism for lubricating both ends of the conveying roller body 3, the output end of the driving motor 2 is connected to the cam 4 through a pulley, and the cam 4 is rotatably connected to one side of one end of the conveying box 1, and both ends of one side of the conveying box 1 are provided with a self-lubricating mechanism for lubricating both ends of the conveying roller body 3 A self-lubricating mechanism for lubricating both ends of the roller body 3 includes a fixed rod 5, and the fixed rod 5 is fixedly connected to both sides of one end of the outside of the conveying box 1. The interior of the fixed rod 5 is connected to an extension rod 6 through a spring, and one side of the interior of the fixed rod 5 is fixedly connected to an oil storage capsule 8, one side of the oil storage capsule 8 is provided with an elastic sheet 7, and the elastic sheet 7 is fixedly connected to the interior of the fixed rod 5, one side of the oil storage capsule 8 is fixedly connected to a nozzle 9, and one side of the nozzle 9 passes through and extends to the outside of the conveying box 1. The cross-section of the conveying roller body 3 is "V"-shaped, and the conveying roller body 3 is symmetrical about the vertical center axis of the conveying box 1.

[0041] In this example, the conveying roller body 3 is driven by the driving motor 2 to convey the steel pipe. When the conveying roller body 3 works for a long time, the pulley connection may become stuck due to insufficient lubrication, affecting the conveying efficiency of the steel pipe. The driving motor 2 will drive the cam 4 to rotate during the rotation, and use the rotation of the cam 4 to squeeze the extension rod 6, so that the extension rod 6 can squeeze the elastic sheet 7 inside the fixed rod 5, so that the oil storage soft capsule 8 on one side of the elastic sheet 7 is squeezed and the lubricating oil drips out through the nozzle 9. Since the fixed rod 5 and the extension rod 6 are connected by a spring, the extension rod 6 will automatically reset and perform repeated self-lubrication operations when it is not pushed by the cam 4.
