Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a steel plate transverse movement device. Background Technology

[0002] Medium and heavy stainless steel plates are generally stainless steel plates with a thickness of 4mm or more, and are widely used in industrial fields such as petroleum, chemical, nuclear power, shipbuilding, and machinery equipment.

[0003] In the production of thick stainless steel plates, a hot roll mill is used, and after rolling, the plates are segmented by a flying shear. The final rolling speed can reach 1.6 m / s. At this time, the time interval between two adjacent steel plates after segmentation is less than 30 seconds. Therefore, three parallel solid melting furnace production lines need to be set up to match the capacity requirements. However, there is currently a lack of effective transverse transfer devices to remove the steel plates from the incoming roller conveyor in a very short time. Otherwise, steel plate collisions are likely to occur. Summary of the Invention

The steel moving trolley is movably mounted on the corresponding track frame. The lifting drive mechanism includes a hydraulic cylinder, a driving crank, a connecting rod, at least one driven crank, and multiple support beams for supporting the track frame. The telescopic end of the hydraulic cylinder is rotatably connected to the driving crank. The connecting rod is connected between the driving crank and the driven crank.

The lifting drive mechanism drives the track frame to fall so that the steel moving trolley is located below the roller surfaces of the first conveyor roller, the second conveyor roller, and the third conveyor roller.

[0013] Furthermore, the track frame is equipped with a tensioning sprocket for tensioning the chain; steering sprockets are respectively provided on both sides of the drive sprocket.

[0014] Furthermore, the steel-moving trolley includes a heat-resistant plate, a car body, and heat insulation pads, slag baffles, and wheels assembled on the car body.

[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 8 As shown, this embodiment provides a steel plate transverse movement device for rapid transverse movement and steel separation of steel plates on a medium-thickness stainless steel hot rolling-online solution treatment integrated production line.

[0029] like Figure 1 As shown, the steel plate transverse transfer device of this embodiment includes a material conveyor 1 for conveying steel plates, a first conveyor 2 for connecting the material conveyor 1, and a second conveyor 3 and a third conveyor 4 disposed on the left and right sides of the first conveyor 2, wherein the left and right directions are defined as transverse directions, and the front and rear directions are defined as longitudinal directions.

[0030] The incoming roller conveyor 1 and the first conveying roller conveyor 2 are arranged longitudinally in the front-to-back direction, while the first conveying roller conveyor 2, the second conveying roller conveyor 3 and the third conveying roller conveyor 4 are arranged laterally in the left-to-right direction.

[0031] Multiple steel plate lateral moving components 5 are respectively provided between the second conveyor roller 3 and the third conveyor roller 4 and the first conveyor roller 2. The steel plate lateral moving components 5 between the second conveyor roller 3 and the first conveyor roller 2 and the steel plate lateral moving components 5 between the third conveyor roller 4 and the first conveyor roller 2 are arranged in an alternating manner to move the steel plates on the first conveyor roller 2 to the second conveyor roller 3 or the third conveyor roller 4 respectively, thereby realizing the rapid lateral moving and steel separation of the steel plates on the first conveyor roller 2.

[0032] The steel plate transverse movement device in this embodiment also includes two chain drive units 6. The steel plate transverse movement components 5 on the same side realize the transverse movement of the steel plate through the corresponding chain drive unit 6.

[0033] like Figure 2 As shown, in this embodiment, the steel plate transverse moving assembly 5 includes a steel moving trolley 51 for carrying the steel plate, a chain 52 for driving the steel moving trolley 51 to move laterally, and a drive sprocket 53 and a driven sprocket 54 for transmitting power to the chain 52.

[0034] like Figure 1 and Figure 3As shown, the chain drive unit 6 includes two motors 61 spaced apart and a drive shaft 62 connected between the two motors 61. One chain drive unit 6 corresponds to the second conveyor roller 3, and the other chain drive unit 6 corresponds to the third conveyor roller 4. At this time, the motors 61 are located at both ends of the second conveyor roller 3 and the third conveyor roller 4 in their longitudinal direction. After the motors 61 are reduced in speed by the reducer 63, the power is transmitted to the corresponding drive shaft 62 through the universal joint. Each drive shaft 62 is equipped with multiple drive sprockets 53 on the same side.

[0035] During operation, the motor 61 drives multiple drive sprockets 53 on the transmission shaft 62 to rotate in both forward and reverse directions. These drive sprockets 54, in turn, rotate in the same direction, causing the corresponding chain 52 to move in both directions. This, in turn, drives the corresponding steel-moving trolley 51 to move laterally between the second conveyor roller 3 and the first conveyor roller 2, or between the third conveyor roller 4 and the first conveyor roller 2, thus completing the lateral movement of the steel plate. Of course, if the lateral movement distance of the steel plate is long, the speed of the chain 52 can be adjusted according to the rolling cycle and transport distance to ensure that the steel plate has a suitable lateral movement speed.

[0036] like Figure 2 As shown, the steel plate transverse moving device in this embodiment also includes multiple track frames 7 that cooperate with the steel plate transverse moving assembly 5 and a lifting drive mechanism 8 for driving the track frames 7 to rise and fall. The steel moving trolley 51 is movably set on the corresponding track frame 7, and under the driving force of the chain 52, the steel moving trolley 51 realizes left and right transverse movement on the track frame 7.

[0037] In this embodiment, the number of lifting drive mechanisms 8 is 8.

[0038] The lifting drive mechanism 8 includes a hydraulic cylinder 81, a driving crank 82, a connecting rod 84, two driven cranks 83, and three support beams 85 for supporting the track frame 7. The telescopic end of the hydraulic cylinder 81 is rotatably connected to the driving crank 82. The connecting rod 84 connects the driving crank 82 and the driven cranks 83. One end of the support beam 85 facing away from the track frame 7 is rotatably connected to the driving crank 82, and the other two support beams 85 are respectively rotatably connected to the two driven cranks 83 at their ends facing away from the track frame 7. Of course, in other embodiments, the number of driven cranks 83 can also be one, and the number of support beams 85 can also be two, depending on the transverse distance of the steel plate.

[0039] like Figure 4 As shown, the driving cranks 82 of two adjacent lifting drive mechanisms 8 are connected by a synchronous shaft 9 to form a group. Of course, each group of lifting drive mechanisms 8 is independent of each other, and the number of groups can be selected according to different steel plate lengths.

[0040] In practice, the incoming roller conveyor 1 is centered, therefore, the first conveying roller conveyor 2 is also centered, and the second conveying roller conveyor 3 and the third conveying roller conveyor 4 are located on the left and right sides of the first conveying roller conveyor 2, respectively.

[0041] Multiple adjacent steel plate transverse moving components 5 are configured as a transverse moving unit. The main drive shafts of two adjacent transverse moving units are flexibly connected by a universal joint to compensate for the effect of the incomplete synchronization of the lifting and lowering of each set of lifting drive mechanisms 8 on the main drive shaft. Multiple main drive shafts are connected by a universal joint to form a drive shaft 62, and each transverse moving unit corresponds to a set of lifting drive mechanisms 8.

[0042] After the thick stainless steel plates are rolled, they are segmented by a flying shear. The segmented steel plates are then straightened by a straightening machine and conveyed to the first conveying roller conveyor 2 via the incoming roller conveyor 1. The first conveying roller conveyor 2 then conveys some of the steel plates to the second conveying roller conveyor 3 and the third conveying roller conveyor 4. Finally, the steel plates conveyed by the first conveying roller conveyor 2, the second conveying roller conveyor 3 and the third conveying roller conveyor 4 are transferred to three parallel solidification furnace production lines to complete online solidification.

[0043] When the steel transfer trolley 51 moves to the initial position or the steel plate transverse position below the first conveyor roller 2, the lifting drive mechanism 8 drives the track frame 7 to rise, so that the steel transfer trolley 51 lifts the steel plate on the first conveyor roller 2 and lifts the steel plate away from the roller surface.

[0044] Next, the chain drive unit 6 drives the corresponding chain 52 to move forward, so as to drive the respective steel transfer trolley 51 to the second conveyor roller 3 or the third conveyor roller 4.

[0045] Then, the lifting drive mechanism 8 drives the track frame 7 to descend, so that the steel transfer trolley 51 descends to below the roller surface of the second conveyor roller 3 or the third conveyor roller 4, and places the steel plate on the steel transfer trolley 51 on the roller surface of the second conveyor roller 3 or the third conveyor roller 4.

[0046] Subsequently, through the reverse movement of chain 52, each steel transfer trolley 51 is moved laterally from below the second conveyor roller 3 or the third conveyor roller 4 to the initial position below the first conveyor roller 2.

[0047] This process is repeated to achieve rapid transverse movement of the steel plate on the first conveyor roller 2, so as to avoid being rear-ended by the next steel plate.

[0048] When steel plates with short intervals on the incoming roller conveyor 1 are rapidly conveyed to the first conveyor roller conveyor 2, multiple steel plate lateral moving components 5 are respectively set between the second conveyor roller conveyor 3 and the third conveyor roller conveyor 4 and the first conveyor roller conveyor 2. The steel plate lateral moving components 5 between the second conveyor roller conveyor 3 and the first conveyor roller conveyor 2 are arranged in an alternating manner with the steel plate lateral moving components 5 between the third conveyor roller conveyor 4 and the first conveyor roller conveyor 2, so as to effectively and quickly move the steel plates on the first conveyor roller conveyor 2 to the second conveyor roller conveyor 3 or the third conveyor roller conveyor 4 respectively, thereby avoiding the steel plates on the first conveyor roller conveyor 2 from colliding.

[0049] In another preferred embodiment, the steel-moving trolleys 51 adjacent to each other in each transverse unit are spaced 2 meters apart, and the steel-moving trolleys 51 in adjacent transverse units are spaced 1 meter apart.

[0050] Further preferred, such as Figure 2 As shown, the track frame 7 is equipped with a tensioning sprocket 55 for tensioning the chain 52, and steering sprockets 56 are respectively provided on both sides of the drive sprocket 53. At this time, the tensioning sprocket 55 and the steering sprockets 56 constitute the tensioning mechanism of this embodiment. Because the chain is relatively long, several support rollers are also provided.

[0051] like Figure 8 As shown, the tensioning sprocket 55 is installed in the elongated hole of the track frame 7 via the pin 71. The two ends of the pin 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. After the tension adjustment is completed, the nuts are tightened.

[0052] When the chain 52 moves forward and backward, the steering sprockets 56 located on both sides of the drive sprocket 53 can ensure that the chain 52 always remains taut, that is, the chain 52 will not come loose, and it is taut in both forward and reverse transmission. This can ensure good stability and reliability when the chain 52 moves, and thus ensure good stability and reliability when the steel moving trolley 51 moves back and forth.

[0053] After prolonged use, the chain 52 will lengthen, and the tension of the chain 52 can be adjusted by using the tension sprocket 55.

[0054] Further preferred, such as Figures 5 to 7 As shown, the steel transfer trolley 51 includes a heat-resistant plate 511, a car body 512, and heat insulation pads 513, slag baffles 514, and wheels 515 assembled on the car body 512. The heat-resistant plate 511 is detachably installed on the side of the heat insulation pad 513 away from the car body 512. The chain 52 is fixed to the car body 512 by a pressure plate. The wheels 515 are rotatably installed 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, the heat insulation pad 513 is a rock wool heat insulation pad, and the rock wool heat insulation pad and the heat-resistant cast iron plate are fixed to the top of the vehicle body 512 by countersunk screws.

[0056] Due to thermal expansion, the heat-resistant plate 511 has a parallelogram cross-sectional shape, and a 1mm gap is reserved between adjacent heat-resistant plates 511.

[0057] The slag baffle 514 is used to prevent iron oxide chips on the surface of the steel plate from falling onto the track of the track frame 7 and accumulating, so as to ensure that the steel transfer trolley 51 moves normally on the track of the track frame 7.

[0058] The body 512 of the steel transfer trolley 51 is processed into a C-shaped structure. When the first conveying roller 2 transports the steel plate, the steel transfer trolley 51 is located below its roller surface. After the steel plate is transported to the lateral position of the first conveying roller 2, the lifting drive mechanism 8 lifts the steel transfer trolley 51 to lift the steel plate away from the roller surface. When the steel transfer trolley 51 transports the steel plate out of the roller area, it leaves a passage for steel passing below it, so as not to affect the transportation of the next steel plate when the rolling rhythm is tight, thereby saving production time.

[0059] In summary, this embodiment uses a 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. This makes the operation stable and reliable, and the operation and maintenance are also simple.

[0060] Furthermore, the bearing housing 10 of the steel plate transverse moving assembly 5 in this embodiment adopts an integral split bearing housing to ensure convenient inspection and maintenance, and its long running distance makes it suitable for working scenarios with large steel moving spans.

[0061] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
