DETAILED DESCRIPTION

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0026] Refer to the following Figures 1 to 3 An automatic replacement and centering device for a starter head of a continuous casting machine according to some embodiments of the present application is described.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, the present application provides an automatic replacement and centering device for the ingot head 112 of a continuous casting machine, comprising: a segmented conveying roller 100, comprising a main conveying roller and a primary centering station and a secondary centering station arranged on the main conveying roller, the end of the main conveying channel extending to the crystallizer loading station, an ingot replacement device 120, for transferring the ingot head 112 to the main conveying roller, an offset monitoring device 130, arranged along the conveying path of the segmented conveying roller 100, for collecting position information of the ingot head 112, a first centering device 140, arranged at the primary centering station, located at the input end of the main conveying channel, for implementing initial position correction of the ingot head 112, a second centering device 150, arranged at the secondary centering station, for performing secondary position correction on the ingot head 112 according to the position information, and a third centering device 160, arranged at the crystallizer loading station, for performing position calibration on the ingot head 112 according to the position information.

[0028] The automatic replacement and centering device for the starter head 112 of the continuous casting machine provided in the present application includes a segmented conveyor roller 100, a starter replacement device 120, an offset monitoring device 130, a first centering device 140, a second centering device 150, and a third centering device 160. A primary centering station and a secondary centering station are provided on the main conveyor roller, and the end of the main conveying channel extends to the crystallizer loading station. The starter head 112 is transported to the main conveyor roller, passes through the primary centering station and the secondary centering station in sequence, and finally arrives at the crystallizer loading station for position calibration. The entire process does not require excessive manual intervention, shortens the time for replacing and centering the starter head 112, and improves the production efficiency of the continuous casting machine. Automated operation reduces the steps of manual handling and centering of the starter head 112, reduces labor costs, and avoids errors that may be caused by manual operation, thereby improving the accuracy and stability of the replacement and centering of the starter head 112.

[0029] A multi-stage centering mechanism is formed by the installation of a first centering device 140, a second centering device 150, and a third centering device 160 at the mold loading station. The primary centering device performs initial position correction on the starter head 112 at the input end of the main conveying channel, providing a basis for subsequent centering. The second centering device 150 performs secondary position correction on the starter head 112 based on position information collected by the deviation monitoring device 130, further improving centering accuracy. The third centering device 160 performs final position calibration at the mold loading station, thereby ensuring the quality and dimensional accuracy of the continuously cast products.

[0030] The deviation monitoring device 130 is arranged along the conveying path of the segmented conveyor roller 100 and is capable of collecting real-time position information of the starter head 112 and promptly feeding this information back to the second and third centering devices 150, 160. This enables the second and third centering devices 150, 160 to adjust their centering strategies and actions in real time based on the actual position of the starter head 112, thereby improving the timeliness and accuracy of centering. During the conveyance of the starter head 112, various factors may cause positional deviations. The real-time monitoring function of the deviation monitoring device 130 enables the system to promptly detect these changes and dynamically adjust the second and third centering devices 150, 160 to ensure that the starter head 112 ultimately remains in the centered position, thus ensuring the continuity and stability of production.

[0031] The automatic replacement and centering device for the starter head 112 of a continuous casting machine provided in this application performs three-way centering of the starter head 112 by installing a first centering device 140, a second centering device 150, and a third centering device 160 at the primary centering station, the secondary centering station, and the mold loading station, respectively. This solves the problem of starter head 112 misalignment, ensures the starter head 112 is symmetrically centered, guarantees stable operation of the equipment, and improves the success rate of casting. The device solves the problems of starter head 112 size misalignment and inaccurate centering position adjustment that are common problems with manual replacement and centering of the starter head 112. The use of the replacement and centering device also reduces the safety risks of operators adjusting the starter head centering online.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments provided in the present application, the ingot replacement device 120 includes: a robotic arm, a hydraulic cylinder, which is arranged on the robotic arm, a clamping mechanism 124, which is arranged on the hydraulic cylinder, the clamping mechanism 124 is used to clamp the ingot head 112, and the hydraulic cylinder is used to drive the clamping mechanism 124.

[0033] In this embodiment, the ingot replacement device 120 includes a robotic arm, a hydraulic cylinder and a clamping mechanism 124. The robotic arm serves as the basic support and moving component of the entire replacement mechanism and has multi-degree-of-freedom movement capabilities. It can flexibly move and rotate in three-dimensional space, so that the clamping mechanism 124 can accurately grasp the ingot head 112 and transfer the ingot head 112 to the main conveyor roller, thereby improving the range and flexibility of the ingot head 112 replacement operation. The hydraulic cylinder is provided on the robotic arm, providing a strong driving force for the clamping mechanism 124. Through the telescopic movement of the hydraulic cylinder, the opening and closing and movement of the clamping mechanism 124 can be accurately controlled to ensure that the clamping mechanism 124 can stably and accurately clamp and release the ingot head 112, meeting the high requirements for movement accuracy and strength during the replacement of the ingot head 112.

[0034] The clamping mechanism 124 is directly used to clamp the starter head 112. It can firmly grasp the starter head 112 during the clamping process, preventing the starter head 112 from slipping or shaking during transportation. This ensures the safety and reliability of the starter head 112 replacement and avoids equipment damage and production interruption caused by the starter head 112 falling.

[0035] like Figure 1 As shown, in some embodiments provided in the present application, the automatic replacement and centering device of the continuous casting machine ingot head 112 also includes: a storage rack 110, having multiple storage areas for storing ingot heads 112 of different specifications, and a control module, which is arranged on the storage rack 110 and electrically connected to the ingot replacement device 120, and is used to issue control instructions to the ingot replacement device 120.

[0036] In this embodiment, the automatic replacement and centering device for the starter heads 112 of a continuous casting machine further includes a storage rack 110 and a control module. The storage rack 110 includes multiple storage areas for categorizing and storing starter heads 112 of different specifications. This enables orderly management of the starter heads 112, facilitates quick search and retrieval, reduces the time required to find the appropriate starter head 112, and improves production preparation efficiency.

[0037] The control module is arranged on the storage rack 110 and is electrically connected to the ingot replacement device 120. It can send control instructions to the ingot replacement device 120 according to production needs to realize automatic selection, transportation and replacement of the ingot head 112, reduce manual intervention and reduce the risk of operational errors.

[0038] like Figure 1 and Figure 3 As shown, in some embodiments provided in the present application, the first centering device 140 includes: at least two first hydraulic cylinders, which are spaced apart on one side of the input end of the main conveying channel, and the at least two first hydraulic cylinders are used to push the ingot head 112 to a preset center reference position through synchronous telescopic action when the ingot head 112 is conveyed to the input end of the main conveying channel.

[0039] In this embodiment, the first centering device 140 includes at least two first hydraulic cylinders. These are spaced apart and positioned on one side of the input end of the main conveying channel. Their synchronized telescoping motion generates a stable and uniform thrust, accurately pushing the starter head 112 to a preset center reference position and effectively eliminating deviations from the starter head 112's initial position.

[0040] The hydraulic cylinder has a fast response speed and can complete the synchronous extension and retraction action in a short time when the ingot head 112 is transported to the input end, quickly achieve centering, reduce the residence time of the ingot head 112 at the input end, improve the continuity and efficiency of the production process, and help to improve the overall production rhythm of the continuous casting machine.

[0041] like Figure 1 and Figure 3 As shown, in some embodiments provided in the present application, the second centering device 150 includes: two groups of second hydraulic cylinders, the two groups of hydraulic cylinders are relatively arranged on both sides of the main conveying roller, and the second hydraulic cylinders are used to correct the position when the offset monitoring device 130 detects that the position of the ingot head 112 is offset. The third centering device 160 includes: two groups of third hydraulic cylinders, the two groups of hydraulic cylinders are relatively arranged on both sides of the main conveying roller, and the third hydraulic cylinder is used to calibrate the position when the offset monitoring device 130 detects that the position of the ingot head 112 is offset.

[0042] In this embodiment, the second centering device 150 and the third centering device 160 each include two sets of hydraulic cylinders. When the deviation monitoring device 130 detects that the starter head 112 is misaligned, the two sets of hydraulic cylinders work together to apply force from both sides, accurately adjusting the starter head 112 to the center position, thereby improving the precision and accuracy of the centering.

[0043] The second centering device 150 performs position correction, while the third centering device 160 performs position calibration, forming a multi-stage centering mechanism. This hierarchical processing method can gradually eliminate the position deviation of the starter head 112, making the centering process more precise, effectively addressing different degrees of misalignment, and further improving the centering effect.

[0044] like Figure 1 As shown, in some embodiments provided in the present application, the automatic replacement and centering device of the continuous casting machine ingot head 112 also includes: an ingot storage device 170, and the ingot storage device 170 includes: a lifting car 172 for carrying and transporting the ingot head 112, a lifting cylinder connected to the lifting car 172, for driving the lifting car 172 to rise or fall along the guide rail, and a limit member 176, which is arranged at the upper end of the guide rail to limit the rising stroke of the lifting car 172.

[0045] In this embodiment, the starter storage device 170 includes a lift trolley 172, a lifting cylinder, and a stopper 176. The lift trolley 172 is driven by the lifting cylinder to rise or fall along the guide rails. The height of the lift trolley 172 can be flexibly adjusted according to the on-site space layout and the storage and retrieval requirements of the starter heads 112. This allows operators to easily load and unload the starter heads 112 at different locations, accommodating different heights of conveyor rollers.

[0046] A limiter 176, located at the upper end of the guide rail, effectively limits the lift trolley 172's upward travel, preventing it from colliding with overhead equipment or structures due to excessive ascent, thereby avoiding equipment damage and safety accidents. This improves the reliability and safety of the device, ensuring the safety of both operators and equipment.

[0047] like Figure 1 As shown, in some embodiments provided in the present application, the ingot storage device 170 further includes: a latch mechanism 178, which is provided at the upper end of the guide rail and is used to lock the lifting vehicle 172 after the lifting vehicle 172 rises to a predetermined position.

[0048] In this embodiment, the starter storage device 170 further includes a latch mechanism 178. The latch mechanism 178 is disposed at the upper end of the guide rail and locks the lift 172 after it has risen to a predetermined position. This effectively prevents the lift 172 from falling or shaking due to unexpected factors (such as hydraulic system failure or external impact), thereby preventing the starter head 112 from falling and causing a safety accident, thereby ensuring the safety of operators and surrounding equipment.

[0049] By locking the lifting vehicle 172, it is ensured to be stable and motionless in the predetermined position, providing precise positioning for subsequent operations such as taking, placing, and replacing the ingot head 112, ensuring that the ingot head 112 can be accurately placed in the specified position, and improving the overall operating accuracy and stability of the ingot head 112 replacement and centering device.

[0050] like Figure 1 As shown, in some embodiments provided in the present application, the automatic replacement and centering device of the continuous casting machine ingot head 112 also includes: a lifting baffle 180, which is arranged at the crystallizer loading station and is used to rise to a lifting height to support the ingot head 112 when the ingot head 112 is calibrated.

[0051] In this embodiment, the automatic replacement and centering device for the starter head 112 of the continuous casting machine further includes a lifting baffle 180. When the starter head 112 is being calibrated, the lifting baffle 180 is raised to a lifting height to support the starter head 112. This effectively prevents the starter head 112 from shifting or shaking due to its own weight or external forces, providing stable support for precise position calibration, ensuring an accurate calibration process, improving the centering accuracy of the starter head 112, and ensuring the smooth progress of subsequent continuous casting production.

[0052] The supporting effect of the lifting baffle 180 reduces the risk of the dart head 112 accidentally falling, avoids injury or damage to the operator and surrounding equipment, and creates a safer environment for the production site.

[0053] The stable support makes the position calibration process more efficient and smooth, reduces the extension of calibration time or repeated calibration caused by the instability of the ingot starter 112, helps to improve the production efficiency of the automatic replacement and centering device of the ingot starter 112 of the entire continuous casting machine, and ensures the continuity and stability of production.

[0054] In some embodiments provided in the present application, the deviation monitoring device 130 includes a plurality of infrared detectors, and the plurality of infrared detectors are respectively arranged at the secondary centering station and the crystallizer loading station.

[0055] In this embodiment, the deviation monitoring device 130 includes multiple infrared detectors. By installing multiple infrared detectors at the secondary alignment station and the mold loading station, the position of the starter head 112 can be monitored from all directions and angles. Using infrared light, the infrared detectors can quickly and accurately capture the position of the starter head 112, promptly detecting any deviation of the starter head 112, as well as the specific direction and extent of the deviation, providing an accurate basis for subsequent position correction and calibration. Real-time monitoring of these two critical stations effectively improves alignment accuracy and ensures product quality.

[0056] like Figure 1 and Figure 3 As shown, in some embodiments provided in the present application, the automatic replacement and centering device of the continuous casting machine ingot head 112 also includes: a hydraulic control system, the hydraulic control system includes: a primary centering hydraulic control system 142, for controlling the first centering device 140, a secondary centering hydraulic control system 154, for controlling the second centering device 150, and a tertiary centering hydraulic control system, for controlling the third centering device 160.

[0057] In this embodiment, the primary centering hydraulic control system 142, the secondary centering hydraulic control system 154, and the tertiary centering hydraulic control system respectively control the first centering device 140, the second centering device 150, and the third centering device 160, enabling precise and independent control of each centering device. Based on the offset of the starter head 112 at different workstations, the parameters of the corresponding hydraulic control system can be adjusted to precisely control the operation of the hydraulic cylinders in each centering device, ensuring that the starter head 112 is accurately centered at different stages.

[0058] like Figure 1 、 Figure 2 、 Figure 3As shown, in a specific embodiment, the present application provides an automatic replacement and centering device for the ingot head 112 of a continuous casting machine, including an intelligent storage device for the ingot head 112, an ingot storage device 170, an ingot replacement device 120, a latch mechanism 178, a first centering device 140, a second centering device 150, a third centering device 160, a lifting baffle 180 and a hydraulic control system.

[0059] The intelligent storage device for the starter head 112 includes: a storage rack 110 and a control module. The storage rack 110 is set in the automatic starter replacement area to facilitate the replacement and storage of the starter head. The starter head 112 is set above the storage rack 110, and the control module is connected to the starter replacement device 120. After the starter replacement device 120 receives the instruction, the robot removes the starter head 112 from the starter and places it in the corresponding area of ​​the intelligent storage device for the starter head 112. At the same time, the system automatically identifies the size specifications required by the production plan, and the robot starts to install the starter head 112. Figure 1 As shown, the storage rack 110 can hold starter heads 112 of five specifications, namely A, B, C, D, and E.

[0060] The starter storage device 170 includes a starter lift carriage (i.e., lift 172), a starter safety latch (i.e., latch mechanism 178), a starter carriage lift cylinder (i.e., lift hydraulic cylinder), and a starter end stop (i.e., limiter 176). The starter is mounted on the starter lift carriage and rises and falls with the hydraulic cylinder. The starter safety latch is located at the highest position of the starter lift carriage (limited by the starter end stop to prevent the starter from rising too far). It serves as a safety device to prevent the starter from sliding down due to external influences, which could cause safety and production accidents.

[0061] The dummy ingot lifting trolley is arranged below the dummy ingot and is used to carry the dummy ingot up and down. The dummy ingot lifting trolley lifting cylinder is arranged below the roller table and is connected to the dummy ingot lifting trolley to provide lifting power to the dummy ingot lifting trolley.

[0062] like Figure 2 As shown, the starter head replacement device 120 includes a dual-output sizing adjustment hydraulic cylinder 126, a chuck (i.e., a clamping mechanism 124), a robotic arm, and an intelligent system. The dual-output sizing adjustment hydraulic cylinder 126 is located at the end of the robotic arm and drives the chuck. The chuck is mounted on the dual-output sizing adjustment hydraulic cylinder 126 and is self-locking via an internal spring. This self-locking spring allows for clamping and releasing the starter head 112. The intelligent system is used to receive, distribute, and execute various commands. The robotic arm provides connection and support, transmitting command movements. The intelligent system is used to receive, distribute, and execute various commands.

[0063] The first centering device 140, when the ingot trolley descends to the roller table to deliver the ingot, the primary centering hydraulic cylinder extends to the ingot centering position. After the centering is completed, the ingot waits to be transported upward.

[0064] The second centering device 150, the ingot starts to enter the secondary centering station, which is before the continuous casting machine fan section 152. When the infrared detector detects that the ingot starts to deviate from the position, the hydraulic device is triggered to operate two sets of hydraulic cylinders to perform secondary precise centering on the ingot starter head 112.

[0065] The third centering device 160, the ingot is transported from the secondary centering station to the crystallizer 162, during which it passes through multiple fan-shaped segments 152. The ingot may be deviated due to various reasons. When the infrared detector detects that the position of the ingot is deviated, it is adjusted. Before the adjustment, the lifting baffle 180 is triggered to prevent the ingot from sliding down. After the lifting baffle 180 is raised, it triggers the fan-shaped segment 152 that clamps the ingot to rise 3 mm, so as to calibrate the position of the ingot head 112.

[0066] The lifting baffle 180 is arranged at the end position of the ingot behind the ingot feeding crystallizer 162 to prevent the ingot from sliding down during the ingot adjustment process.

[0067] like Figure 3 As shown, the hydraulic control system includes a guide ingot safety pin hydraulic control system 179, a size specification adjustment hydraulic control system 122, a lifting vehicle hydraulic control system 174, a primary centering hydraulic control system 142, a secondary centering hydraulic control system 154, a tertiary centering hydraulic control system and a lifting baffle hydraulic control system 182.

[0068] The dummy bolt safety latch hydraulic control system 179 consists of a two-position, four-way solenoid directional control valve, two throttle valves, and two hydraulic locks, all interconnected by hydraulic piping. The lifting hydraulic cylinder is controlled by a solenoid directional control valve. Throttle valves control the oil flow rate to the rod and rodless chambers of the hydraulic cylinder, ensuring smooth operation. A hydraulic lock is installed in the rodless chamber of the hydraulic cylinder to effectively prevent pressure loss during operation and the possibility of a fall.

[0069] The hydraulic control system 122 for size adjustment includes a two-position, four-way solenoid reversing valve, a dual-output spring-locking hydraulic cylinder, two throttle valves, two hydraulic locks, and a safety relief valve. These hydraulic components are connected via hydraulic piping. The dual-output spring-locking hydraulic cylinder is controlled by a two-position, four-way solenoid reversing valve. The throttle valve controls the oil inlet speed, ensuring smooth operation when adjusting the opening of the blank holder on both sides. The hydraulic system is equipped with a safety relief valve to activate overflow and provide overload protection when the pressure exceeds the negative limit during opening adjustment. A hydraulic lock is installed on the hydraulic cylinder inlet pipe, allowing the hydraulic cylinder piston rod to start and stop at any position within its travel range.

[0070] The lift truck hydraulic control system 174 consists of a two-position, four-way solenoid directional control valve, two throttle valves, and two hydraulic locks, all interconnected by hydraulic piping. The lift hydraulic cylinder is controlled by a solenoid directional control valve. Throttle valves control the oil flow rate to the rod chamber and rodless chamber of the hydraulic cylinder, ensuring smooth operation. A hydraulic lock is installed in the rodless chamber of the hydraulic cylinder to effectively prevent pressure loss during operation, which could cause the ingot to slide down the roller table and potentially interrupt production.

[0071] The single-stage centering hydraulic control system 142 comprises a three-position, four-way solenoid directional valve with a "Y"-shaped center position, two one-way throttle valves, two hydraulic locks, and two sets of tandem throttle valves. Hydraulic piping connects the hydraulic components. The travel hydraulic cylinders are controlled by a solenoid directional valve. Two sets of tandem throttle valves synchronize the speed of the two travel hydraulic cylinders, ensuring synchronized position during operation. A hydraulic lock is provided in the rodless chamber of the hydraulic cylinder, allowing the travel hydraulic cylinder piston rod to start and stop at any position within its travel range. These two sets of tandem throttle valves maintain the normal movement of the hydraulic cylinder piston rod while precisely controlling its speed. Synchronous operation of the hydraulic cylinders can be achieved by simply adjusting the corresponding one-way throttle valve spool opening under conditions of equal flow. This adjustment allows precise control of the extension and retraction speed of each hydraulic cylinder's piston rod. This highly accurate and reliable adjustment method meets the high-precision requirements of the dummy bar centering hydraulic synchronization circuit.

[0072] Both the secondary and tertiary centering hydraulic control systems 154 and 155 include two sets of three-position, four-way solenoid directional valves with a Y-shaped centering function, two sets of one-way throttle valves, two sets of hydraulic locks, and four sets of tandem throttle valves. Hydraulic piping connects these hydraulic components. The travel hydraulic cylinders are controlled by a single solenoid directional valve. Four sets of tandem throttle valves synchronize the speed of the two travel hydraulic cylinders, ensuring synchronized position during operation. A hydraulic lock is provided in the rodless chamber of the hydraulic cylinder, allowing the travel hydraulic cylinder piston rods to start and stop at any position within their travel range.

[0073] The hydraulic control system 182 for the baffle lift consists of a two-position, four-way solenoid directional valve, two throttle valves, and two hydraulic locks, all interconnected by hydraulic piping. The lift hydraulic cylinder is controlled by a solenoid directional valve. Throttle valves control the oil flow rate to the rod and rodless chambers of the hydraulic cylinder, ensuring smooth operation. A hydraulic lock is installed in the rodless chamber of the hydraulic cylinder to effectively prevent pressure loss during operation, which could cause the guide ingot to slide down the roller table and potentially interrupt production.
