Description

Technical Field

[0001] This invention relates to the technical field of steel plate conveying, and specifically to a steel plate edge alignment device for table unloading. Background Technology

[0002] Currently, in the thick plate production line, after rolling, the steel plate is placed on a stand for uniform cooling, and then the stand unloading device performs edge-aligning operations. It is then conveyed to the shearing line by roller conveyor. The commonly used stand unloading edge-aligning method is as follows: the chain conveys the steel plate to the unloading roller conveyor, then the edge stop is raised, the conveyor chain reverses to move the steel plate, and the edge of the steel plate is aligned with the stop on one side. The edge stop is lowered, and after the conveyor chain falls, the steel plate is placed on the roller conveyor, and the edge-aligning process is completed.

[0003] In the above-mentioned process of aligning the steel plate during the unloading and edge-mounting of the steel plate, the alignment is achieved by continuously dragging the steel plate with a chain. This method has the following two main drawbacks: 1. During the transverse conveying of steel plates on the cooling bed, offset from the roller conveyor line is inevitable. Therefore, during the edge alignment process, when one end of the steel plate is aligned, the other end is not yet aligned. The chain needs to continue dragging the steel plate to achieve complete alignment. The surface of the aligned end of the steel plate will slide relative to the corresponding chain plate surface, and the lower surface of the steel plate will have scratches of varying degrees. The greater the weight of the steel plate, the more likely it is to be scratched, which seriously affects the surface quality of the product and causes a series of economic losses.

[0004] 2. The existing method of aligning the steel plate on the cutting platform relies entirely on manual visual inspection to determine whether the steel plate is in place and to decide whether to stop the chain reversal. There are no detection methods. As a result, the steel plate is often aligned with the edge, but the chain still reverses and pulls the steel plate, causing serious scratches on the lower surface of the steel plate. Summary of the Invention

[0005] The purpose of this invention is to provide a steel plate edge alignment device for table unloading, which can not only automatically and quickly align the steel plate to the edge, but also reduce scratches on the lower surface of the steel plate and improve product quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A steel plate alignment device for table-type unloading includes a platform base, a lifting mechanism, and an alignment mechanism. The lifting mechanism and the alignment mechanism are mounted on the platform base. The lifting mechanism includes a crossbeam and a drive assembly for lifting the crossbeam. Multiple rollers are arranged along the length of the upper surface of the crossbeam, with the central axes of the rollers parallel to each other. The alignment mechanism includes a first hydraulic cylinder and a pusher trolley. The first hydraulic cylinder drives the pusher trolley to move horizontally reciprocally, and the direction of movement of the pusher trolley is parallel to the crossbeam. Along the length direction, the upper surface of the platform base is provided with two first limiting holes, and the two ends of the crossbeam are provided with limiting support rods that can be inserted into the first limiting holes one by one. The driving assembly includes a second hydraulic cylinder, a push rod, and two swing arms. The bottom of the two swing arms is set on the upper surface of the platform base through a hinge seat. The middle part of the two swing arms is connected to the two ends of the push rod through a hinge. The second hydraulic cylinder drives the push rod, and the push rod drives the two swing arms. The top of the two swing arms lifts up or disengages from the bottom of the crossbeam.

[0007] Furthermore, the top of the swing arm is provided with a first roller assembly arranged horizontally, and the bottom of the crossbeam frame is provided with a rectangular frame, with the first roller assembly abutting against the inner side of the rectangular frame.

[0008] Furthermore, the second hydraulic cylinder is inclinedly mounted on the upper surface of the platform base via a hinge seat, and the output end of the second hydraulic cylinder is hinged to the side of the push rod via a hinge member.

[0009] Furthermore, the lifting mechanism also includes two bosses, which are disposed on the upper surface of the platform base. The two bosses and the platform base form a recess, and the driving component is located inside the recess. The two first limiting holes are located one-to-one on the upper surface of the two bosses.

[0010] Furthermore, the pushing mechanism also includes a base, the upper surface of the platform base is provided with a second limiting hole, the base is inserted into the second limiting hole through a limiting plate, the guide rail groove is horizontally arranged on the base, the pushing block trolley is movably arranged on the guide rail groove through a second roller assembly, the first hydraulic cylinder is arranged on the platform base through a rotating shaft support, the output end of the first hydraulic cylinder is connected to the bottom of the pushing block trolley through a hinge, and the upper surface of the end of the pushing block trolley is provided with a pushing block.

[0011] Furthermore, a spring is provided inside the guide rail groove, with one end of the spring pressing against the side of the second roller assembly and the other end of the spring pressing against the inner wall of the guide rail groove.

[0012] Furthermore, the pusher trolley is equipped with a rotary motor, which drives the pusher block to rotate around its longitudinal central axis.

[0013] Furthermore, the platform base includes a first base and a second base, which are fixedly connected by a mounting plate. The lifting mechanism is located on the first base, and the leveling mechanism is located on the second base.

[0014] Furthermore, one end of the idler roller is a conical roller, and the diameter of one end of the idler roller is smaller than the diameter of the other end.

[0022] The technical solutions in the embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a steel plate unloading and edge alignment device includes a platform base 1, a lifting mechanism 2, and an alignment mechanism 3. The lifting mechanism 2 and the alignment mechanism 3 are mounted on the platform base 1. The lifting mechanism 2 includes a crossbeam frame 210 and a drive assembly 220 for driving the crossbeam frame 210 to rise and fall. Multiple rollers 211 are arranged along the length of the upper surface of the crossbeam frame 210, with the central axes of the rollers 211 parallel to each other. The alignment mechanism 3 includes a first hydraulic cylinder 310 and a pusher trolley 320. The first hydraulic cylinder 310 drives the pusher trolley 320 to move horizontally reciprocally. The direction of movement of the pusher trolley 320 is parallel to the length of the crossbeam frame 210. In the direction, the upper surface of the platform base 1 is provided with two first limiting holes 230, and the two ends of the crossbeam frame 210 are provided with limiting support rods 240 that can be inserted into the first limiting holes 230 one by one. The driving assembly 220 includes a second hydraulic cylinder 221, a push rod 222, and two swing arms 223. The bottom of the two swing arms 223 is set on the upper surface of the platform base 1 through a hinge seat. The middle part of the two swing arms 223 is connected to the two ends of the push rod 222 through a hinge. The second hydraulic cylinder 221 drives the push rod 222, and the push rod 222 drives the two swing arms 223. The top of the two swing arms 223 lifts up or disengages from the bottom of the crossbeam frame 210.

[0024] In this embodiment, the device is installed at the gap between the rollers of the roller conveyor 6. When the steel plate on the roller conveyor 6 needs to be aligned with the edge, the drive assembly 220 drives the crossbeam frame 210 to rise, and the crossbeam frame 220 lifts the steel plate so that the steel plate and the roller do not contact each other. The first hydraulic cylinder 310 drives the push block trolley 320, and the push block trolley 330 pushes the steel plate from the side, so that the steel plate moves along the length of the roller until the steel plate is aligned and abuts against the edge of the roller conveyor 6. The lower surface of the steel plate forms relative rolling with the support roller 211 of the crossbeam frame 220, which reduces frictional resistance, reduces scratches on the steel plate, improves product quality, avoids additional scratch repair processes, and improves production efficiency.

[0025] Understandably, when steel plate edge alignment is not required, the drive assembly 220 will lower the crossbeam frame 210 to a position below the roller, and the push block trolley 330 will be placed beside the roller conveyor 6 under the drive of the first hydraulic cylinder 310, thereby ensuring the normal movement of the steel plate on the roller conveyor 6. In addition, multiple edge alignment devices can be configured for the roller conveyor 6 according to actual needs, ensuring that the steel plate can be aligned at any position on the roller conveyor 6 using this device.

[0026] It should be noted that during the process of raising or lowering the crossbeam frame 210, the output end of the second hydraulic cylinder 221 drives the two swing arms 223 through the push rod 222, causing the tops of the two swing arms 223 to lift or detach from the bottom of the crossbeam frame 210. The combination of the limiting support rod 240 and the first limiting hole 230 can keep the position of the crossbeam frame 210 unchanged, ensuring that the swing arms 223 and the crossbeam frame 210 can be aligned vertically, thus achieving stable lifting and lowering of the crossbeam frame 210. In addition, on the one hand, only one second hydraulic cylinder 221 is needed to raise and lower the crossbeam frame 210, saving power resource costs and reducing equipment space occupation. On the other hand, when it is not necessary to lift the steel plate, the swing arms 223 are separated from the crossbeam frame 210, and there is no need to continuously support the crossbeam frame 210. The crossbeam frame 210 is supported by the limiting support rod 240, which extends the service life of the drive component 220 and reduces the number of maintenance times of the drive component 220.

[0027] It should be noted that both the hinge base and the hinge component are detachable structures, which facilitates the replacement and maintenance of the drive assembly 220.

[0028] The top of the swing arm 223 is provided with a horizontally arranged first roller assembly 224, and the bottom of the crossbeam frame 210 is provided with a rectangular frame 212. The first roller assembly 224 abuts against the inner side of the rectangular frame 212. The swing arm 223 lifts the crossbeam frame 210 through the first roller assembly 224. During this process, the relative sliding between the swing arm 223 and the crossbeam frame 210 changes to relative rolling, reducing mutual wear. At the same time, the first rolling assembly 224 moves within the rectangular frame 212, forming a connection between the swing arm 223 and the crossbeam frame 210, ensuring the stable lifting and lowering of the crossbeam frame 210.

[0029] The second hydraulic cylinder 221 is inclinedly mounted on the upper surface of the platform base 1 via a hinge seat. The output end of the second hydraulic cylinder 221 is hinged to the side of the push rod 222 via a hinge member. The second hydraulic cylinder 221 is inclined and connected to the side of the push rod 222. Depending on the position of the push rod 222, the hinge seat and hinge member allow the tilt angle of the second hydraulic cylinder 221 to change accordingly, ensuring the stabilizing effect of the second hydraulic cylinder 221 on the push rod 222, while further reducing the space occupied by the device.

[0030] The lifting mechanism 2 also includes two bosses 4, which are disposed on the upper surface of the platform base 1. The two bosses 4 and the platform base 1 form a recess 5, and the drive assembly 220 is located within the recess 5. The two first limiting holes 230 are located one-to-one on the upper surface of the two bosses 4. The function of the bosses 4 is to support the crossbeam frame 210 and, according to actual site requirements, to adjust the height position of the crossbeam frame 210. By using bosses 4 of different heights, the crossbeam frame 210 can be adapted to roller conveyors 6 of different heights, ensuring stable lifting of the steel plate and preventing the crossbeam frame 210 from obstructing the normal transport of the steel plate. In addition, considering the position limitation of the drive assembly 220 in the recess 5, which is the middle position of the crossbeam frame 210, the drive assembly 220 can fully and stably lift the crossbeam frame 210.

[0031] The pushing mechanism 3 also includes a base 330. The upper surface of the platform base 1 is provided with a second limiting hole 340. The base 330 is inserted into the second limiting hole 340 through a limiting plate 350. The guide rail groove 331 is horizontally arranged on the base 330. The pushing block trolley 320 is movably arranged on the guide rail groove 331 through a second roller assembly 321. The first hydraulic cylinder 310 is arranged on the platform base 1 through a rotating shaft support 311. The output end of the first hydraulic cylinder 310 is connected to the bottom of the pushing block trolley 320 through a hinge. The upper surface of the end of the pushing block trolley 320 is provided with a pushing block 322. The combination of the limiting plate 350 and the second limiting hole 340 is used to limit the horizontal displacement of the base 330. At the same time, the combination of the guide rail groove 331 and the second roller assembly 321 is used to prevent the push block trolley 320 from moving or deviating. In addition, rotating the shaft of the rotating shaft support 311 can adjust the tilt of the first hydraulic cylinder 310, thereby raising the height of the push block trolley 320 so that the push alignment block 322 can be adapted to the height of the steel plate, ensuring the stable execution of the steel plate edge alignment operation.

[0032] A spring 332 is provided inside the guide rail groove 331. One end of the spring 332 presses against the side of the second roller assembly 321, and the other end presses against the inner wall of the guide rail groove 331. The spring 332 is used to control the position of the second roller assembly 321. When the first hydraulic cylinder 310 does not apply force to the pusher trolley 320, the spring 332 enables the pusher trolley 321 to automatically and quickly return to its original standby position.

[0033] The pusher trolley 320 is equipped with a rotary motor 323, which drives the alignment block 322 to rotate around its longitudinal central axis. To address any misalignment of the steel plate on the roller conveyor 6, the rotary motor 323 enables the alignment block 322 to automatically follow the steel plate's deviation, ensuring a certain length of contact surface between the alignment block 322 and the steel plate. This guarantees the steel plate can be safely and stably aligned to the edge, preventing damage during alignment and achieving automatic protection of the steel plate.

[0034] The platform base 1 includes a first base 110 and a second base 120, which are fixedly connected by a mounting plate 130. The lifting mechanism 2 is located on the first base 110, and the alignment mechanism 3 is located on the second base 120. The platform base 1 can be divided into the first base 110 and the second base 120, thereby allowing the lifting mechanism 2 and the alignment mechanism 3 to be separated. The distance and position of the lifting mechanism 2 and the alignment mechanism 3 are controlled according to the length of the mounting plate 130. At the same time, the mounting plate 130 also allows the device to be directly installed on the base support of the roller conveyor 6. The installation positions of the lifting mechanism 2 and the alignment mechanism 3 are allocated according to the actual number of devices on site and the length of the roller conveyor 6, ensuring that the steel plate can stably perform the edge alignment operation at any position on the roller conveyor.

[0035] One end of the idler roller 211 is a conical roller, and the diameter of one end of the idler roller 211 is smaller than the diameter of the other end. When the steel plate moves on the roller conveyor 6, the inclined surface of the conical roller can be used to straighten the steel plate, ensuring that the steel plate can be pushed horizontally onto the upper surface of the idler roller 211, thus achieving stable lifting and edge alignment operations.
