Description

Technical Field

[0001] The present invention relates to the technical field of hot-rolled steel strip transportation, and particularly to a handling device for hot-rolled steel strips. Background Art

[0002] When hot-rolled steel strips are transported, they are transported in a coiled form, also known as hot-rolled steel coils. Hot-rolled steel coils are transported through roller trays. Because the steel coils are heavy, when they stop during transportation, the inertia of the steel coils is relatively large. The inertia of the steel coils will cause the displacement of the lower rollers and the tray, affecting the accuracy of steel coil transportation. Moreover, the inertia of the steel coils will impact the transmission mechanism. After being impacted, the transmission mechanism will cause friction, thus affecting the service life of the transmission mechanism. And the strong inertia will also cause extrusion at the position where the steel coil contacts the transmission mechanism, and the surface of the steel coil is easily deformed and scratched.

A stepped shaft 316 is rotatably connected inside the second support plate 35. The two stepped shafts 316 are symmetrically arranged.

The third one-way gear 311 is engaged with the first rack 314 and the second rack 315.

[0050] The driving mechanism 4 includes a motor 41 fixed to one side of the base 13. A gear 42 is fixed to the output end of the motor 41. One side of the gear 42 is engaged with the first one-way gear 216, and the other side is engaged with the second one-way gear 33.

[0051] One side of the base 13 is fixedly provided with an inertia controller, the inertia controller is wirelessly connected to the controller of the conveying mechanism 1, and the inertia controller is electrically connected to the motor 41, the hydraulic cylinder and the oil pump.

[0052] Working principle:

[0053] The controller controls the roller shaft 12 to operate so that the base 13 moves on the roller shaft 12. When the base 13 moves, it drives the steel coil inertia processing mechanism one 2, the steel coil inertia processing mechanism two 3 and the steel coil 318 to move. When the controller needs to stop the movement of the base 13, it sends a stop operation instruction to the inertia controller. The inertia controller controls the hydraulic cylinder 217 to contract in advance, pulls out the inner rod from the card slot 218, releases the limit between the moving seat 29 and the mounting plate 23, so that the moving seat 29 can slide on the guide rod one 25 through the slider 28, and then controls the motor 41 to drive the gear 42 to rotate forward. The forward rotation of the gear 42 meets the rotation direction of the one-way gear one 216 driving the rotating shaft 214. The rotation of the rotating shaft 214 drives the bevel gear one 215 to rotate. The bevel gear one 215 drives the bevel gear two 212 and the double-section reciprocating threaded rod one 211 to rotate, so that the two moving blocks one 22 move away from each other. When moving away, it drives the mounting plate 23 and the structures above the moving seat 29 to move along, away from the steel coil 318. At this time, the bottom of the steel coil 318 is suspended without support, and the center of gravity is located at the top of the two stepped shafts 316;

[0054] When the base 13 suddenly brakes and stops, the steel coil 318 will swing on the stepped shaft 316 due to inertia, and a part of the inertia is removed by swinging the steel coil 318. During the swinging process, the motor 41 is controlled to drive the gear 42 to rotate in reverse, so that the one-way gear two 33 meets the rotation direction of driving the double-section reciprocating threaded rod two 32 to rotate. The rotation of the double-section reciprocating threaded rod two 32 makes the two moving blocks two 34 drive the structures such as the support plate two 35 to move away from each other;

[0055] The support plate two 35 drives the structures such as the gear shaft one 37, the stepped shaft 316, the bevel gear three 38, the bevel gear four 39, the gear shaft two 310 and the one-way gear three 311 to move. When the one-way gear three 311 moves, it first meshes with the rack two 315. When meshing, the moving direction of the one-way gear three 311 does not meet the rotation direction of the rack two 315 to drive the gear shaft two 310 to rotate. When the stepped shaft 316 moves, multiple steps will cause the steel coil 318 to have a short-distance falling action during the swinging process, and the swinging is interfered by the falling force, thereby reducing the inertia generated by the swinging;

[0056] Then start the motor 41 to drive the gear 42 to rotate forward, causing the double-section reciprocating threaded rod one 211 to rotate, so that the two moving blocks one 22 at the reciprocating thread end of the double-section reciprocating threaded rod one drive structures such as the moving seat 29 to approach the steel coil 318. When the lower part of the steel coil 318 swings, it will contact the gradually approaching moving seat 29. After the moving seat 29 receives the thrust from the steel coil 318, it will move by squeezing the spring 26 through the slider 28. The two moving seats 29 contact the swinging steel coil 318 and unload the force on it, reducing the swinging amplitude of the steel coil 318 and reducing the impact of the inertia of the steel coil 318 on the conveying mechanism 1;

[0057] When the steel coil 318 stops swinging, start the hydraulic cylinder 217 to insert the inner rod into the inside of the card slot 218 to limit the moving seat 29. Then, when continuing to approach, the two moving seats 29 support the steel coil 318. Then start the motor 41 to drive the gear 42 to rotate in reverse, causing the double-section reciprocating threaded rod two 32 to continue to rotate, so that the two moving blocks two 34 continue to move away, causing the one-way gear three 311 to mesh with the rack one 314. When the one-way gear three 311 moves in this direction and meshes with the rack one 314, it satisfies the steering for driving the gear shaft two 310 to rotate, causing the one-way gear three 311 to drive the gear shaft two 310 and the bevel gear four 39 to rotate. The bevel gear four 39 drives the bevel gear three 38 and the gear shaft one 37 to rotate, causing the stepped shaft 316 to rotate 180 degrees, making the slope 317 face upward. After facing upward, the moving block two 34 moves to the thread end of the reciprocating thread. At this time, the stepped shaft 316 is completely withdrawn from the steel coil 318. In this state, the steel coil 318 can be loaded and unloaded. If there is no need for loading and unloading, the moving block two 34 that continues to move to the thread end of the reciprocating thread drives the upper structure to return. When resetting, the rack one 314 meshes with the one-way gear three 311 again, but the moving direction during resetting makes the one-way gear three 311 not satisfy the steering for driving the gear shaft two 310 to rotate, so that the slope 317 always faces upward. Then re-insert into the inner ring of the steel coil 318. When inserting into the inner ring, the multiple slopes 317 sequentially contact the inner wall of the top of the steel coil 318. When inserting the steel coil 318, the steel coil 318 is lifted. Then the one-way gear three 311 meshes with the rack two 315. In this direction, the meshing of the one-way gear three 311 and the rack two 315 satisfies the steering for driving the gear shaft two 310 to rotate, so that the stepped shaft 316 rotates 180 degrees, turning the slope 317 downward and the step upward, facilitating subsequent inertia processing. Then start the motor 41 to drive the gear 42 to rotate forward to make the two moving seats 29 re-insert under the steel coil 318 to support the steel coil 318, protecting the steel coil 318 during transportation.

[0058] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention by making equivalent substitutions or changes according to the technical solution and inventive concept of the present invention.
