Description

Technical Field

[0002] Hot-rolled steel strips are transported in coils, also known as hot-rolled steel coils. Hot-rolled steel coils are transported on roller pallets. Due to the heavy weight of the steel coils, the inertia of the steel coils is also relatively large when they stop during transportation. The inertia of the steel coils will cause the rollers and pallets below to shift, affecting the accuracy of steel coil transportation. In addition, the inertia of the steel coils will impact the transmission mechanism, which will cause friction after the transmission mechanism is impacted, thereby affecting the service life of the transmission mechanism. In addition, the strong inertia will also cause extrusion at the contact point between the steel coils and the transmission mechanism, and the surface of the steel coils is prone to deformation and scratches.

[0030] The driving mechanism 4 includes a motor 41 fixed to one side of the base 13 , and a gear 42 is fixed to the output end of the motor 41 . One side of the gear 42 is meshed with the one-way gear 1 216 , and the other side is meshed with the one-way gear 2 33 .

[0031] An inertial controller is fixed to one side of the base 13 . The inertial controller is wirelessly connected to the controller of the conveying mechanism 1 . The inertial controller is electrically connected to the motor 41 , the hydraulic cylinder and the oil pump.

[0032] Working principle: 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 1 2, the steel coil inertia processing mechanism 2 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 command to the inertia controller. The inertia controller controls the hydraulic cylinder 217 to contract in advance, pulls the inner rod out of the slot 218, releases the limit of the moving seat 29 and the mounting plate 23, and allows the moving seat 29 to slide on the guide rod 1 25 through the slider 28, and then controls the electric The machine 41 drives the gear 42 to rotate forward, and the forward rotation of the gear 42 satisfies the direction of the rotation of the one-way gear 1 216 to drive the rotating shaft 214 to rotate. The rotation of the rotating shaft 214 drives the bevel gear 1 215 to rotate, and the bevel gear 1 215 drives the bevel gear 2 212 and the double-section reciprocating threaded rod 1 211 to rotate, so that the two moving blocks 1 22 move away from each other, and when moving away, the mounting plate 23 and the upper moving seat 29 and other structures are driven to move with them, 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; When the base 13 stops suddenly, the steel coil 318 will swing on the stepped shaft 316 due to inertia. By swinging the steel coil 318, a part of the inertia is removed. During the swinging process, the motor 41 is controlled to drive the gear 42 to reverse, so that the one-way gear 2 33 can drive the two-stage reciprocating threaded rod 2 32 to rotate. The two-stage reciprocating threaded rod 2 32 rotates to make the two moving blocks 2 34 drive the support plate 2 35 and other structures to move away from each other. The support plate 2 35 drives the gear shaft 1 37, the stepped shaft 316, the bevel gear 3 38, the bevel gear 4 39, the gear shaft 2 310 and the one-way gear 3 311 to move. When the one-way gear 311 moves, it first meshes with the rack 2 315. When meshing, the moving direction of the one-way gear 311 does not meet the direction of the rack 2 315 to drive the gear shaft 2 310 to rotate. When the stepped shaft 316 moves, multiple steps will cause the steel coil 318 to fall down a short distance when it swings, and the swing is disturbed by the falling force, thereby reducing the inertia generated by the swing. Then, the motor 41 is started to drive the gear 42 to rotate forward to rotate the double-stage reciprocating threaded rod 1 211, so that the two moving blocks 1 22 that move to the reciprocating thread tail of the double-stage reciprocating threaded rod 1 drive the moving seat 29 and other structures 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 contacts the thrust of the steel coil 318, it will move through the slider 28 to squeeze the spring 26. The two moving seats 29 contact the steel coil 318 in the swinging process and unload the force on it, thereby reducing the swing amplitude of the steel coil 318 and reducing the influence of the inertia of the steel coil 318 on the conveying mechanism 1. When the steel coil 318 stops swinging, the hydraulic cylinder 217 is started to insert the inner rod into the slot 218, limiting the moving seat 29, and then when it continues to approach, the two moving seats 29 hold the steel coil 318, and then the motor 41 is started to drive the gear 42 to reverse, so that the double-section reciprocating threaded rod 2 32 continues to rotate, so that the two moving blocks 2 34 continue to move away, so that the one-way gear 311 is meshed with the rack 1 314, and the one-way gear 311 moves in this direction when it is fully meshed with the rack 1 314. The foot drives the gear shaft 2 310 to rotate, so that the one-way gear 311 drives the gear shaft 2 310 and the bevel gear 4 39 to rotate, and the bevel gear 4 39 drives the bevel gear 3 38 and the gear shaft 1 37 to rotate, so that the stepped shaft 316 rotates 180 degrees, so that the slope 317 faces upward, and the moving block 2 34 moves to the wire tail of the reciprocating thread after facing upward. At this time, the stepped shaft 316 is completely pulled out of the steel coil 318. In this state, the steel coil 318 can be loaded and unloaded. If loading and unloading is not required, continue to move to the upward direction. The moving block 2 34 of the tail of the compound thread drives the upper structure to return to its original position. When resetting, the rack 1 314 re-engages with the one-way gear 3 311, but the moving direction of the reset makes the one-way gear 3 311 not meet the direction of driving the gear shaft 2 310 to rotate, so that the slope 317 is always facing upward, and then the inner ring of the steel coil 318 is reinserted. When the inner ring is inserted, multiple slopes 317 contact the inner wall of the top of the steel coil 318 in turn, and when the steel coil 318 is inserted, the steel coil 318 moves up, and then The one-way gear three 311 is meshed with the rack two 315. In this direction, the meshing of the one-way gear three 311 and the rack two 315 satisfies the direction of driving the gear shaft two 310 to rotate, thereby rotating the step shaft 316 180 degrees, turning the slope 317 downward and the step upward to facilitate subsequent inertia processing. Then the motor 41 is started to drive the gear 42 to rotate forward so that the two moving seats 29 are reinserted under the steel coil 318 to support the steel coil 318 and protect the steel coil 318 during transportation.
