[0026] To further illustrate the embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, mainly used to illustrate the embodiments, and can be combined with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible embodiments and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0028] Refer to Figures 1 to 8 As shown, this embodiment provides a steel plate transverse shifting device for the rapid transverse shifting and steel separation of steel plates on a medium and heavy plate stainless steel hot rolling - on - line solution annealing integrated production line.
[0029] As Figure 1 shown, the steel plate transverse shifting device of this embodiment includes an incoming material roller table 1 for conveying steel plates, and also includes a first conveying roller table 2 connected to the incoming material roller table 1, and second conveying roller tables 3 and third conveying roller tables 4 arranged on the left and right sides of the first conveying roller table 2. Among them, the left - right direction is defined as the transverse direction, and the front - back direction is defined as the longitudinal direction.
[0030] The incoming material roller table 1 and the first conveying roller table 2 are longitudinally arranged in the front - back direction, and the first conveying roller table 2, the second conveying roller table 3, and the third conveying roller table 4 are transversely arranged in the left - right direction.
[0031] A plurality of steel plate transverse shifting components 5 are respectively arranged between the second conveying roller table 3 and the third conveying roller table 4 and the first conveying roller table 2. The steel plate transverse shifting components 5 between the second conveying roller table 3 and the first conveying roller table 2 and the steel plate transverse shifting components 5 between the third conveying roller table 4 and the first conveying roller table 2 are arranged in a staggered manner to respectively transverse the steel plates on the first conveying roller table 2 to the second conveying roller table 3 or the third conveying roller table 4, that is, to realize the rapid transverse shifting and steel separation of the steel plates on the first conveying roller table 2.
[0032] The steel plate transverse shifting device of this embodiment further includes two chain drive units 6. The steel plate transverse shifting components 5 on the same side respectively realize the transverse shifting of the steel plates through the corresponding chain drive units 6.
[0033] As Figure 2 shown, in this embodiment, the steel plate transverse shifting component 5 includes a steel plate transfer trolley 51 for carrying the steel plate, a chain 52 for driving the transverse shifting of the steel plate transfer trolley 51, and a driving sprocket 53 and a driven sprocket 54 for drivingly connecting the chain 52.
[0034] As Figure 1 and Figure 3As shown, the chain drive unit 6 includes two motors 61 arranged at a distance and a transmission shaft 62 connected between the two motors 61. One chain drive unit 6 corresponds to the second conveying roller path 3, and the other chain drive unit 6 corresponds to the third conveying roller path 4. At this time, the motors 61 are respectively located at both ends of the second conveying roller path 3 and the third conveying roller path 4 in their longitudinal directions. After the motors 61 are decelerated by the speed reducers 63, the power is transmitted to the corresponding transmission shafts 62 through universal shafts, and each transmission shaft 62 is respectively equipped with a plurality of driving sprockets 53 on the same side as it.
[0035] During operation, the motors 61 drive the plurality of driving sprockets 53 on the transmission shaft 62 to rotate correspondingly through forward and reverse rotations, and cooperate with the corresponding driven sprockets 54 to drive the corresponding chains 52 to move forward and backward, thereby driving the corresponding steel transfer carts 51 to traverse between the second conveying roller path 3 and the first conveying roller path 2 or between the third conveying roller path 4 and the first conveying roller path 2 to cooperate to complete the transverse movement of the steel plate. Of course, when the transverse movement distance of the steel plate is relatively long, the movement speed of the chain 52 can be adjusted accordingly according to the rolling rhythm and the transportation distance to ensure that the steel plate has an appropriate transverse movement speed.
[0036] As Figure 2 shown, the steel plate transverse movement device of this embodiment further includes a plurality of track frames 7 cooperating with the steel plate transverse movement assembly 5 and a lifting drive mechanism 8 for driving the track frames 7 to lift and lower. The steel transfer cart 51 is movably arranged on the corresponding track frame 7, and under the driving force of the chain 52, the steel transfer cart 51 realizes left and right transverse movement on the track frame 7.
[0037] In this embodiment, the number of the lifting drive mechanisms 8 is 8.
[0038] The lifting drive mechanism 8 includes 1 hydraulic cylinder 81, 1 active crank 82, 1 connecting rod 84, two driven cranks 83, and 3 support beams 85 for supporting the track frame 7. The telescopic end of the hydraulic cylinder 81 is rotatably connected to the active crank 82, and a connecting rod 84 is connected between the active crank 82 and the driven cranks 83. One end of one support beam 85 facing away from the track frame 7 is rotatably connected to the active crank 82, and the other two ends of the other two support beams 85 facing away from the track frame 7 are respectively rotatably connected to the two driven cranks 83. Of course, in other embodiments, the number of the driven cranks 83 can also be 1, and the number of the support beams 85 can also be 2. Its specific number is determined by the transverse movement distance of the steel plate.
[0039] As Figure 4 shown, the active cranks 82 of two adjacent lifting drive mechanisms 8 are connected through a synchronizing shaft 9 and form a group. Of course, each group of lifting drive mechanisms 8 is independent, and the number of groups put into use can be selected according to different steel plate lengths.
[0040] During specific implementation, the incoming material roller table 1 is centered, so the first conveying roller table 2 is also centered, and the second conveying roller table 3 and the third conveying roller table 4 are respectively located on the left and right sides of the first conveying roller table 2.
[0041] A plurality of steel plate transverse movement components 5 adjacent to each other are set as a transverse movement unit. The main drive shafts of two adjacent transverse movement units are flexibly connected through a universal shaft to compensate for the influence on the main drive shaft caused by the incomplete synchronization of the lifting of each set of lifting drive mechanisms 8. The plurality of main drive shafts are connected through universal shafts to form a drive shaft 62, and each transverse movement unit corresponds to a set of lifting drive mechanisms 8.
[0042] After medium and heavy plate stainless steel is rolled and segmented by a flying shear, the segmented steel plates are straightened by a straightening machine, and then conveyed to the first conveying roller table 2 through the incoming material roller table 1. Then, the first conveying roller table 2 conveys some steel plates to the second conveying roller table 3 and the third conveying roller table 4 respectively. After that, the steel plates conveyed by the first conveying roller table 2, the second conveying roller table 3 and the third conveying roller table 4 are transferred to three parallel solution annealing furnace production lines to complete on-line solution annealing.
[0043] When the steel plate transfer trolley 51 moves to the initial position or the steel plate transverse movement position below the first conveying roller table 2, the lifting drive mechanism 8 drives the track frame 7 to rise, so that the steel plate transfer trolley 51 jacks up the steel plate on the first conveying roller table 2 to lift the steel plate off the roller table surface.
[0044] Then, the chain drive unit 6 drives the corresponding chain 52 to move forward to drive their respective steel plate transfer trolleys 51 to the second conveying roller table 3 or the third conveying roller table 4.
[0045] Then, the lifting drive mechanism 8 drives the track frame 7 to descend, so that the steel plate transfer trolley 51 descends below the roller table surface of the second conveying roller table 3 or the third conveying roller table 4, and places the steel plate on the steel plate transfer trolley 51 on the roller table surface of the second conveying roller table 3 or the third conveying roller table 4.
[0046] After that, through the reverse movement of the chain 52, the respective steel plate transfer trolleys 51 are respectively horizontally moved from below the second conveying roller table 3 or the third conveying roller table 4 to the initial position below the first conveying roller table 2.
[0047] Run repeatedly in this way to achieve rapid horizontal movement of the steel plate on the first conveying roller table 2 to avoid being rear-ended by the next steel plate.
[0048] When steel plates on the incoming roller 1 with a very short distance between each other are quickly conveyed to the first conveyor roller 2, a plurality of steel plate transverse shifting assemblies 5 are respectively arranged between the second conveyor roller 3 and the third conveyor roller 4 and the first conveyor roller 2, and the steel plate transverse shifting assemblies 5 between the second conveyor roller 3 and the first conveyor roller 2 and the steel plate transverse shifting assemblies 5 between the third conveyor roller 4 and the first conveyor roller 2 are arranged in an alternating manner, so as to effectively and quickly transversely shift the steel plates on the first conveyor roller 2 to the second conveyor roller 3 or the third conveyor roller 4, respectively, thereby avoiding rear-end collision of the steel plates on the first conveyor roller 2.
[0049] In another preferred embodiment, adjacent steel-moving trolleys 51 in each transverse shifting unit are spaced 2 meters apart from each other, and the steel-moving trolleys 51 in adjacent transverse shifting units are spaced 1 meter apart from each other.
[0050] Further preferably, Figure 2 As shown, the track frame 7 is equipped with a tensioning sprocket 55 for tensioning the chain 52, and a steering sprocket 56 is provided on both sides of the driving sprocket 53. At this time, the tensioning sprocket 55 and the steering sprocket 56 constitute the tensioning mechanism of this embodiment. Because the chain is long, a plurality of supporting wheels are also provided.
[0051] like Figure 8 As shown, the tensioning sprocket 55 is installed in the long hole of the track frame 7 through the pin shaft 71, and the two ends of the pin shaft 71 are connected to the tensioning frame 72. The relative position between the track frame 7 and the tensioning frame 72 is adjusted by bolts and nuts to tension the chain 52, and the nuts can be tightened after the tensioning adjustment is completed.
[0052] When the chain 52 moves forward and reversely, the steering sprockets 56 located on both sides of the driving sprocket 53 can ensure that the chain 52 always remains in a taut state, that is, the chain 52 will not loosen, and is tight during forward and reverse transmission. This can ensure that the chain 52 can achieve good stability and reliability when moving, and further ensure that the steel transfer trolley 51 can achieve good stability and reliability when moving back and forth.
[0053] When the chain 52 is used for a long time, the chain 52 will become longer, and the tightness of the chain 52 can also be adjusted by the tensioning sprocket 55 .
[0054] Further preferably, Figures 5 to 7 As shown, the steel moving trolley 51 includes a heat-resistant plate 511, a car body 512, and a heat-insulating pad 513, a slag baffle 514 and a wheel 515 assembled on the car body 512. The heat-resistant plate 511 is detachably arranged on the side of the heat-insulating pad 513 away from the car body 512. The chain 52 is fixed to the car body 512 through a pressure plate. The wheel 515 is rotatably arranged on the track of the track frame 7, and the cross-sectional shape of the car body 512 is C-shaped.
[0055] In this specific embodiment, the heat-resistant plate 511 is a heat-resistant cast iron plate, and the heat-insulating pad 513 is a rock wool heat-insulating pad. The rock wool heat-insulating pad and the heat-resistant cast iron plate are fixed to the top of the vehicle body 512 by countersunk head screws.
[0056] Due to the factor of thermal expansion, the cross-sectional shape of the heat-resistant plate 511 is a parallelogram, and a 1-mm gap is reserved between adjacent heat-resistant plates 511.
[0057] The slag baffle 514 is used to prevent the iron oxide chips on the surface of the steel plate from falling onto the track of the track frame 7 and forming a pile, so as to ensure the normal movement of the steel transfer trolley 51 on the track of the track frame 7.
[0058] The vehicle body 512 of the steel transfer trolley 51 is processed into a C-shaped structure. When the first conveying roller table 2 conveys the steel plate, the steel transfer trolley 51 is located below its roller table surface; when the steel plate is laterally shifted on the first conveying roller table 2, the lifting drive mechanism 8 raises the steel transfer trolley 51 to lift the steel plate off the roller table surface; when the steel transfer trolley 51 transports the steel plate out of the roller table area, a steel passing channel is left below it, which is convenient for the transportation of the next steel plate without affecting it when the rolling rhythm is compact, thereby saving production time.
[0059] In summary, this embodiment uses the chain 52 to drive the steel transfer trolley 51, and there is no relative movement between the steel plate and the steel transfer trolley 51 during lateral movement. In this way, the operation is stable and reliable, and the operation and maintenance are also simple.
[0060] In addition, the bearing seat 10 of the steel plate lateral movement assembly 5 in this embodiment adopts an integral split bearing seat to ensure convenient maintenance and a long operating distance, which is suitable for working scenarios with a large steel transfer span.
[0061] Although the present invention is specifically shown and described in combination with the preferred implementation embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them are within the protection scope of the present invention.
