Description

Technical Field

[0001] This utility model relates to the technical field of slab processing equipment, and in particular to a slab processing centering and positioning device. Background Technology

[0002] A slab, a type of steel billet, is formed by continuous casting of molten steel using a continuous casting machine. It is primarily used for rolling plates. On the production line, slabs are typically transported by a conveyor system to various processing stations. During this transport, the slab's position inevitably shifts. Small, insignificant shifts do not significantly affect processing; however, significant displacement can cause the slab to collide with subsequent processing equipment, resulting in damage. Even if a slab with excessive displacement can still enter the processing area... Within the processing station, quality problems may also occur in the subsequently processed boards. At present, the repositioning of the slabs is mostly done by push plates, that is, movable push plates are set on both sides of the conveying device. Once it is found that the slab has shifted too much, the push plates are controlled to push the slab to reposition. However, since the pushing direction of the push plates is not consistent with the transmission direction of the conveying rollers, each push causes friction between the slabs and the conveying rollers. This not only makes it difficult to shift the slabs, but also damages the conveying rollers and the slabs, which brings great inconvenience to the slab processing operation. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a slab processing centering and positioning device, thereby effectively solving the shortcomings of the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a slab processing centering and adjusting device, including a conveying platform, on which conveying rollers are provided, the conveying rollers being driven to rotate by a motor, sensing components being provided on both sides of the conveying platform at positions corresponding to their feeding ends, a lifting platform being provided inside the conveying platform below the corresponding conveying rollers, the lifting platform being located behind the sensing components, guide wheel sets being provided on the conveying platform at positions corresponding to the gaps between each conveying roller, the conveying rollers rotating along the front-back direction of the conveying platform, the guide wheel sets rotating along the left-right direction of the conveying platform, and adjusting plates being provided on the platform surface at positions corresponding to the lifting platforms, the sensing components controlling the operation of the motor, the lifting platform, and the adjusting plates.

[0005] Furthermore, the sensing component includes mounting plates disposed on both sides of the conveying platform and movable left and right. A rotatable sensing plate is disposed on the side of the mounting plate facing the conveying roller. A proximity switch is also disposed on the mounting plate. The sensing plate and the proximity switch cooperate to control the operation of the motor, the lifting platform and the adjustment plate.

[0006] Furthermore, the mounting plate has a mounting shaft on one side near the feeding start of the conveying platform. The rear end of the sensing plate is hinged to the mounting shaft, and the front end of the sensing plate is inclined toward the conveying roller. The proximity switch is set at the corresponding tilted front end of the sensing plate. A reset spring is also provided in the middle of the sensing plate. One end of the reset spring is connected to the sensing plate, and the other end of the reset spring is connected to the mounting plate.

[0007] Furthermore, drive cylinders are provided on both sides of the conveying platform at the positions of the corresponding sensing components, the piston rods of the drive cylinders on both sides are arranged opposite to each other, and the mounting plate is fixedly connected to the piston rods of the drive cylinders.

[0008] Furthermore, a jack is provided at the lower end of the conveying platform, and the lifting platform is mounted on the piston rod of the jack. Several guide wheel sets are provided on the lifting platform at positions corresponding to the gaps between each set of conveying rollers.

[0009] Furthermore, the guide wheel assembly includes a base disposed on the top of the lifting platform, a wheel seat disposed on the top of the base, and a guide wheel disposed on the wheel seat. The guide wheel can rise with the lifting platform and extend above the conveyor roller.

[0010] Furthermore, drive cylinders are also provided on both sides of the conveying platform at positions corresponding to the adjustment plate, and the adjustment plate is mounted on the piston rod of the drive cylinder.

[0011] The above-mentioned technical solution of this utility model has the following beneficial effects: This utility model sets sensing components and adjusting plates on both sides of the conveying platform, and sets a lifting platform and guide wheel group below the conveying roller. With the cooperation of multiple mechanisms, once the excessive displacement of the slab is detected, the guide wheel group will rise and lift the slab on the conveying roller. Since the rotation direction of the guide wheel group is consistent with the movement direction of the adjusting plate, the position of the slab can be easily corrected. This can also avoid rigid friction between the slab and the conveying roller, thus avoiding damage to the equipment. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-3 As shown in the figure, the slab processing centering and adjusting equipment described in this embodiment includes a conveying platform 1, on which a conveying roller 2 is provided. The conveying roller 2 is driven to rotate by a motor 3. Sensing components are provided on both sides of the conveying platform 1 at positions corresponding to the two ends of its feeding. A lifting platform 4 is also provided inside the conveying platform 1 at a position below the corresponding conveying roller 2. The lifting platform 4 is located behind the sensing components. A guide wheel set is provided on the conveying platform 1 at a position corresponding to the gap between each conveying roller. The conveying roller 2 rotates in the front-back direction of the conveying platform 1, and the guide wheel set rotates in the left-right direction of the conveying platform 1. Adjusting plates 5 are also provided on the platform of the conveying platform 1 at positions corresponding to the two sides of the lifting platform 4. The sensing components control the operation of the motor 3, the lifting platform 4, and the adjusting plates 5.

[0018] The sensing component includes mounting plates 6 that are disposed on both sides of the conveying platform 1 and can move left and right. A rotatable sensing plate 7 is provided on the side of the mounting plate 6 facing the conveying roller 2. A proximity switch 8 is also provided on the mounting plate 6. The sensing plate 7 and the proximity switch 8 work together to control the operation of the motor 3, the lifting platform 4 and the adjustment plate 5.

[0019] An installation shaft 9 is provided on the mounting plate 6 on one side near the feeding start end of the conveying platform 1. The rear end of the sensing plate 7 is hinged to the installation shaft 9. The front end of the sensing plate 7 is inclined towards the conveying roller 2. The proximity switch 8 is located at the corresponding tilted front end of the sensing plate 7. A reset spring 10 is also provided in the middle of the sensing plate 7. One end of the reset spring 10 is connected to the sensing plate 7, and the other end of the reset spring 10 is connected to the mounting plate 6.

[0020] Drive cylinders 11 are installed on both sides of the conveying platform 1 at the positions of the corresponding sensing components. The piston rods of the drive cylinders 11 on both sides are arranged opposite to each other, and the mounting plate 6 is fixedly connected to the piston rods of the drive cylinders 11.

[0021] A jack 12 is installed at the lower end of the conveying platform 1, and a lifting platform 4 is installed on the piston rod of the jack 12. Several guide wheel sets are installed on the lifting platform 4 at the positions corresponding to the gaps between each set of conveying rollers 2.

[0022] The guide wheel assembly includes a base 13 set on the top of the lifting platform 4, a wheel seat 14 set on the top of the base 13, and a guide wheel 15 set on the wheel seat 14. The guide wheel 15 can be raised with the lifting platform 4 and extend above the conveyor roller 2.

[0023] On both sides of the conveying platform 1, at the corresponding positions of the adjustment plate 5, there are also drive cylinders 16, and the adjustment plate 5 is mounted on the piston rod of the drive cylinder 16.

[0024] The slab is conveyed on the conveying platform. Unless it is affected by a huge external force, it will not have a long displacement deviation. During normal conveying, the conveying platform is also equipped with a pressure roller group (not shown in the figure) above its feeding start end. It can play a certain role in fixing the slab. However, after the slab passes through the pressure roller group, it may have a small displacement due to small vibration. Even if the displacement of the slab exceeds the error value of the conveying deviation, its displacement distance will not be too large. That is, the slab will not have a long displacement deviation during conveying. Therefore, the slab will not have excessive collision with the sensing component.

[0025] The working principle of this utility model is as follows: The slab is conveyed on the conveying roller 2. According to the specifications of the slab and the requirements for offset error, the piston rod of the drive cylinder 11 is controlled to extend synchronously, and the sensing components on both sides move towards one side of the conveying roller 2. The slab passes between the sensing components on both sides. When the slab is being conveyed normally, the sensing components on both sides will not be triggered, and the slab can be conveyed normally. Once the offset distance of the slab exceeds the allowable error value, when the slab is conveyed to the sensing component, it will come into contact with the sensing plate 7. As the slab applies external force to the sensing plate 7, the sensing plate 7 will rotate along the mounting shaft 9. When the sensing plate 7 rotates, it will squeeze the return spring 10, and the front end of the sensing plate 7 that is tilted inward towards the conveying platform 1 will come into contact with the sensing end of the proximity switch 8. At this time, the proximity switch 8 is triggered and sends a signal to control the motor 3 to stop. The conveying roller 2 will no longer perform conveying operations, and then the piston rod of the jack 12 extends upward. This controls the lifting platform 4 to move upward. The guide wheel assembly on the lifting platform 4 extends out at the gap between the conveying rollers 2. The guide wheel 15 on the guide wheel assembly contacts the bottom of the slab and pushes the slab up on the conveying roller 2. Then, the two drive cylinders 16 control the two adjustment plates 5 to move synchronously to one side of the slab. The adjustment plate 5 pushes the slab on the guide wheel 15, which can avoid wear on the surface of the slab and make the adjustment of the slab smoother. After the slab is corrected and reset by the adjustment plate 5, the jack 12 controls the lifting platform 4 to move downward. The guide wheel assembly is retracted to the bottom of the conveying roller 2 and the adjustment plate 5 is separated from the two sides of the slab. The slab is placed back on the conveying roller 2. Finally, the motor 3 starts and makes the slab after correction and centering continue to be conveyed. At the same time, as the slab separates from the sensing plate 7, the sensing plate 7 will be reset by the action of the reset spring 10, which facilitates subsequent monitoring and sensing.

Many modifications and variations will be apparent to those skilled in the art.
