Description

Technical Field

[0001] The present invention relates to the technical field of steel coil transportation, and particularly relates to an automatic rotating pallet device for steel coils on a steel coil transportation line. Background Art

[0002] The transportation of hot-rolled steel coil products in a factory needs to achieve efficient and safe circulation within a limited space. Usually, a crane is directly used for hoisting. To reduce the dependence on the crane, an electric flat car or a special pallet truck may also be used for transportation. When a traditional pallet truck transports silicon steel or hot-formed steel, it is easy to cause the coil to collapse and deform the steel coil. Therefore, the top of the pallet truck needs to be changed to rollers and rotate during transportation.

[0003] Currently, the automatic rotating pallet device for steel coils on a steel coil transportation line is driven by a motor. The motor drives the rollers on the pallet truck to rotate, thereby driving the rotation of the steel coil.

[0004] Motor drive requires electrical support and needs long drag chains or cable brushes, which are too large on a finished product transportation line of nearly 100 meters and cannot meet the cost and safety requirements.

[0005] Therefore, the inventor of the present invention, relying on years of experience and practice in the relevant industry, proposes an automatic rotating pallet device for steel coils on a steel coil transportation line to overcome the defects of the prior art. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic rotating pallet device for steel coils on a steel coil transportation line, which solves the problems of requiring electrical support and having a complex structure when the pallet rollers are driven to rotate by a motor during transportation. The present invention does not require motor assistance, and cleverly transmits the force of the walking of the pallet transportation part through mechanical linkage to drive the rotation of the steel coil, ensuring the transportation efficiency while also ensuring that the steel coil will not be damaged during transportation, and can also achieve synchronous control of mobile transportation and rotation.

[0007] The purpose of the present invention is achieved as follows. An automatic rotating pallet device for steel coils on a steel coil transportation line includes:

[0008] A pallet transportation part for moving and transporting steel coils along the running direction of the steel coil transportation line; a set of roller supports for supporting the steel coil is arranged on the pallet transportation part;

[0009] A roller mechanical linkage part includes a rack arranged along the running direction of the steel coil transportation line. A gear that can mesh and rotate with the rack is arranged on the pallet transportation part. A transmission structure that can drive the rotation of the rollers is connected to the gear. The gear that meshes and rotates along the rack drives the set of roller supports to rotate through the transmission structure, so as to drive the steel coil supported on the set of roller supports to rotate.

[0010] In a preferred embodiment of the present invention, the transmission structure is a chain transmission structure, which includes a first sprocket, a chain and a second sprocket. The first sprocket can rotate under the drive of the gear, the second sprocket is connected to the roller group, and the chain is sleeved on the first sprocket and the second sprocket.

[0011] In a preferred embodiment of the present invention, a gear shaft for articulating the gear is provided on the pallet transport portion, a reducer structure is connected to the gear shaft, and a low-speed output shaft of the reducer structure is connected to the first sprocket.

[0012] In a preferred embodiment of the present invention, a roller seat is provided on the pallet transport portion, and the roller group includes at least one pair of rollers arranged on both sides of the steel coil, and each of the rollers is hinged to the roller seat through a roller shaft; the second sprocket is connected to the roller shaft of the roller of at least one side of the steel coil in the roller group.

[0013] In a preferred embodiment of the present invention, a first self-lubricating bearing is provided between the gear and the gear shaft.

[0014] In a preferred embodiment of the present invention, a second self-lubricating bearing is provided between the first sprocket and the low-speed output shaft.

[0015] In a preferred embodiment of the present invention, a third self-lubricating bearing is provided between the second sprocket and the roller shaft.

[0016] In a preferred embodiment of the present invention, the chain is a high-strength alloy steel chain.

[0017] In a preferred embodiment of the present invention, the pallet transport unit includes a pallet transport vehicle, and the pallet transport vehicle can move along the steel coil transport line to transport the steel coil.

[0018] In a preferred embodiment of the present invention, the rack is fixedly mounted on the roller cover of the steel coil transport line.

[0019] As described above, the steel coil automatic rotating tray device for a steel coil transport line of the present invention has the following beneficial effects:

[0020] The present invention can cleverly utilize the relative displacement generated during the operation of the steel coil transport line itself, and generate driving force through relative movement, and realize passive power transmission through the meshing action of the gears and racks on the pallet transport part, so that the roller group that traditionally requires independent motor drive can operate autonomously through mechanical linkage.

[0021] The transmission structure realizes power transmission through mechanical linkage, ensuring that the steel coils rotate stably and at a constant speed during transportation.

[0022] The present invention ingeniously utilizes the force generated by the movement of the pallet transportation unit to drive the rotation of the steel coil, preventing phenomena such as coil collapse during the transportation of materials like silicon steel and hot-formed steel. This not only ensures the transportation efficiency but also guarantees that the steel coil will not be damaged during transportation, and can also achieve synchronous control of mobile transportation and rotation.

[0023] The idler roller group of the present invention no longer requires a motor to drive the rotation. This not only effectively reduces the power consumption and the cost of purchasing motors but also significantly simplifies the equipment layout structure, solves the problems of large space occupation and complex circuits in the traditional transmission system, and at the same time reduces the equipment maintenance frequency.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0040] As Figure 1 、 Figure 2 、 Figure 3 shown, the present invention provides an automatic rotating pallet device for steel coils on a steel coil transportation line, including:

[0041] A pallet transportation unit 1 for moving and transporting a steel coil 3 along the running direction of the steel coil transportation line 4; a roller group 11 on the pallet transportation unit 1 for supporting the steel coil 3.

[0042] A roller mechanical linkage unit 2 includes a rack 21 arranged along the running direction of the steel coil transportation line 4, a gear 22 disposed on the pallet transportation unit 1 that can mesh and rotate with the rack 21, and a transmission structure connected to the gear 22 that can drive the roller group 11 to rotate. The gear 22 meshing and rotating along the rack 21 drives the roller group 11 to rotate through the transmission structure, so as to drive the steel coil 3 supported on the roller group 11 to rotate.

[0043] In the present invention, the rack 21 is arranged along the running direction of the steel coil transportation line 4. While the pallet transportation unit 1 moves and transports the steel coil 3 along the running direction of the steel coil transportation line 4, the gear 22 on the pallet transportation unit 1 is driven to rotate through the meshing action between the gear 22 and the rack 21; the gear 22 drives the roller group 11 to rotate through the transmission structure, so as to drive the steel coil 3 supported on the roller group 11 to rotate.

[0044] The contact surface between the idler roller group 11 and the steel coil 3 drives the steel coil 3 to slowly rotate by friction. Its low-friction design can effectively prevent scratches on the surface of the steel coil 3 during rotation. The mechanical linkage part 2 of the idler roller realizes power transmission through mechanical linkage, ensuring that the steel coil 3 rotates stably and uniformly during transportation.

[0045] In a conventional steel coil transportation system, the roller path motor transmits power to the roller path drive shaft through a planetary reducer, drives the drive chain at the bottom of the trolley track to rotate through a double-row roller chain transmission mechanism, and drives the tray device to make continuous step-by-step movements along the track direction through sprocket engagement. Its multi-stage transmission structure requires an independent power unit and lubrication system.

[0046] The present invention can cleverly utilize the relative displacement generated during the operation of the steel coil transportation line 4 itself, and generate a driving force through relative motion. Through the meshing of the gear 22 and the rack 21 on the tray transportation part 1, passive power transmission is achieved, enabling the idler roller group 11 that traditionally requires an independent motor drive to operate autonomously through mechanical linkage.

[0047] The present invention cleverly uses the force of the tray transportation part 1 walking to drive the steel coil to rotate, preventing phenomena such as coil collapse when transporting materials such as silicon steel and hot-formed steel. While ensuring the transportation efficiency, it also guarantees that the steel coil will not be damaged during transportation, and can also achieve synchronous control of mobile transportation and rotation.

[0048] The idler roller group of the present invention no longer needs to be driven by a motor to rotate, which not only effectively reduces power consumption and the cost of purchasing motors, but also significantly simplifies the equipment layout structure, solves the problems of large space occupation and complex circuits of the traditional transmission system, and at the same time reduces the equipment maintenance frequency.

[0049] Furthermore, as Figure 1 、 Figure 2 shown, the transmission structure is a chain transmission structure, which includes a first sprocket 23, a chain 24 and a second sprocket 25. The first sprocket 23 can rotate under the drive of the gear 22. The second sprocket 25 is connected to the idler roller group 11, and the chain 24 is sleeved on the first sprocket 23 and the second sprocket 25.

[0050] As Figure 1 、 Figure 2As shown, the roller on one side of the steel coil 3 in the roller assembly 11 is the drive roller 111, and the roller on the other side is the idler roller 112. The drive roller 111 is connected to the second sprocket 25, and the gear 22 drives the drive roller 111 through a chain drive mechanism. Friction between the drive roller 111 and the steel coil 3 causes the steel coil 3 to slowly rotate. The idler roller 112 on the other side provides radial support, and its low-friction design effectively prevents scratches on the steel coil surface during rotation. This transmission structure achieves power transmission through mechanical linkage, ensuring stable and uniform rotation of the steel coil during transportation.

[0051] Further, if Figure 1 、 Figure 2 As shown, a gear shaft for articulating the gear 22 is provided on the pallet transport portion 1 , the gear shaft is connected to a reducer structure 26 , and the low-speed output shaft of the reducer structure 26 is connected to the first sprocket 23 .

[0052] The reducer structure 26 is a planetary gear reducer, and the gear shaft can directly constitute the high-speed input shaft of the reducer structure 26 (the high-speed input shaft can also use a separate transmission shaft, which is coaxially connected to the gear shaft through a coupling or other structure). The reducer structure 26 reduces speed through the internal planetary gears, and the torque is output through the low-speed output shaft of the reducer structure 26.

[0053] Further, if Figure 1 As shown, a roller seat 12 is provided on the pallet transport portion 1, and the roller group 11 includes at least one pair of rollers (drive roller 111, idler roller 112) arranged on both sides of the steel coil 3, and each roller is hinged to the roller seat 12 through a roller shaft; the roller shaft of at least the roller (drive roller 111) arranged on one side of the steel coil 3 in the roller group 11 is connected to the second sprocket 25.

[0054] Furthermore, a first self-lubricating bearing is provided between the gear 22 and the gear shaft.

[0055] Furthermore, a second self-lubricating bearing is provided between the first sprocket 23 and the low-speed output shaft.

[0056] Furthermore, a third self-lubricating bearing is provided between the second sprocket 25 and the roller shaft.

[0057] Furthermore, the chain 24 is a high-strength alloy steel chain.

[0058] The power decelerated by the reducer structure 26 is transmitted through the low-speed output shaft of the reducer structure 26, the first sprocket 23, and the chain 24 to the second sprocket 25 at the end of the idler shaft, which is used to drive the idler to rotate and drive the steel coil 3 to rotate slowly during transportation. This chain drive structure adopts a modular design, selects a high-strength alloy steel chain and a self-lubricating bearing, which significantly improves the transmission synchronization while ensuring the bearing capacity. The mechanical linkage eliminates the collaborative error of multiple motors, reduces the energy consumption while decreasing the equipment failure rate, and its open structure is more convenient for later maintenance operations.

[0059] Further, as Figure 1 , Figure 3 shown, the pallet transportation part 1 includes a pallet transport vehicle, which can move along the steel coil transportation line 4 to transport the steel coil 3.

[0060] Further, as Figure 3 shown, the rack 21 is fixedly arranged on the roller way cover plate of the steel coil transportation line 4.

[0061] In an embodiment of the present invention, the steel coil transportation line 4 includes a trolley transporting roller way 41, a roller way motor 42 is arranged beside the trolley transporting roller way 41, and the roller way motor 42 drives the pallet transportation part 1 to move along the trolley transporting roller way 41.

[0062] Install a rack 21 above the trolley transporting roller way (prior art), and add a gear 22 to the pallet transportation part 1 (on the steel coil transport vehicle). The gear 22 meshes with the rack 21, so that when the pallet transportation part 1 moves, the gear 22 can drive the high-speed input shaft of the reducer structure 26 to rotate. After being decelerated by the reducer structure 26, it drives the first sprocket 23 on the low-speed output shaft to rotate, and then drives the idler to rotate through the chain 24 and the second sprocket 25.

[0063] As described above, the steel coil automatic rotation pallet device of the steel coil transportation line of the present invention has the following beneficial effects:

[0064] The present invention can cleverly utilize the relative displacement generated during the operation of the steel coil transportation line itself, and generate a driving force through relative motion. Through the meshing of the gear and the rack on the pallet transportation part, passive power transmission is achieved, enabling the traditional idler group that requires independent motor drive to operate independently through mechanical linkage.

[0065] The transmission structure realizes power transmission through mechanical linkage, ensuring that the steel coil rotates stably and uniformly during transportation.

[0066] The present invention cleverly uses the force of the pallet transportation part walking to drive the rotation of the steel coil, preventing phenomena such as coil collapse when transporting materials such as silicon steel and hot-formed steel. While ensuring the transportation efficiency, it also ensures that the steel coil will not be damaged during transportation, and can also achieve synchronous control of mobile transportation and rotation.

[0067] The idler set of the present invention does not need to be driven by a motor to rotate anymore, which not only effectively reduces the power consumption and the motor procurement cost, but also significantly simplifies the equipment layout structure, solves the problems of large space occupation and complex circuits of the traditional transmission system, and at the same time reduces the equipment maintenance frequency.

[0068] The above are only illustrative specific embodiments of the present invention and are not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the scope of protection of the present invention.
