Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in an "or" relationship.

[0044] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings. Figures 1 to 7 A bidirectional overturning ladle turnover machine 100, a control device and a system provided by the present application are described in detail below through specific embodiments and application scenarios.

[0045] Some embodiments of the present application disclose a bidirectional overturning ladle turning machine 100, comprising a rack 110, a ladle turning arm 120, a first locking piece 130, a second locking piece 140, a driving piece 150 and a limiting piece 160.

[0046] As shown in Figure 1 , Figure 2 and Figure 4 , the ladle turning arm 120 is arranged on the rack 110, and the ladle turning arm 120 is used for connecting with the ladle 300. The ladle 300 is a core bearing container used for safely containing, transporting and temporarily storing molten metal (such as molten iron and molten steel) in a high-temperature state. The ladle turning arm 120 is arranged on the rack 110 and used for connecting with the ladle 300, and this kind of structure design makes the whole overturning torque be borne by the solid rack 110, thereby ensuring the high stability and controllability of the ladle turning process.

[0047] As shown in Figure 1 , Figure 2 and Figure 4 , the moving platform 170 is used for placing the ladle 300; through the movement of the moving platform 170, the ladle 300 is connected with or separated from the ladle turning arm 120. As a controllable transport carrier, the moving platform 170 can accurately move the heavy ladle 300 to the predetermined connection position of the ladle turning arm 120, realize quick centering and automatic connection, save the cumbersome steps of repeatedly using the overhead crane for hoisting and transporting, greatly improve the operation rhythm and efficiency, and greatly reduce the safety risks and operation difficulties caused by hoisting and transporting shaking and inaccurate positioning.

[0048] As shown in Figure 1 and Figure 2 , the first locking piece 130 is arranged on the rack 110 and can be connected with or separated from the ladle turning arm 120; the second locking piece 140 is arranged on the rack 110 and can be connected with or separated from the ladle turning arm 120; when the first locking piece 130 is connected with the ladle turning arm 120 and the second locking piece 140 is separated from the ladle turning arm 120, the ladle turning arm 120 can rotate around the first locking piece 130; when the second locking piece 140 is connected with the ladle turning arm 120 and the first locking piece 130 is separated from the ladle turning arm 120, the ladle turning arm 120 can rotate around the second locking piece 140. Through the alternate connection and separation of the first locking piece 130, the second locking piece 140 and the ladle turning arm 120, the ladle turning arm 120 obtains two different rotation fulcrums, thereby realizing the bidirectional controllable overturning of the ladle 300 around different axes on the same device; this not only saves the cumbersome steps of hoisting and transporting the ladle 300 for different processes such as pouring and slagging, but also significantly improves the operation efficiency, and more importantly, the structure is simple and reliable, and a complex translation or rotation mechanism is not needed, thereby enhancing the functionality of the device and ensuring the rigidity and stability of the system.

[0049] As shown in Figure 1 , Figure 2And Figure 4 As shown in the figure, the driving member 150 is arranged on the rack 110 and connected with the ladle arm 120 to drive the rotation of the ladle arm 120. The driving member 150 is directly arranged on the rack 110 and connected with the ladle arm 120, and such a layout structure is compact and the power transmission path is direct, which can provide strong and stable torque for the rotation of the ladle arm 120, and ensure that the ladle 300 can still realize extremely stable, slow and precise controllable bidirectional tilting action under the full load state of containing high-temperature molten metal, thereby ensuring the process quality and operation safety of pouring and slagging operations.

[0050] As shown in the figure, Figure 5 The first locking member 130 includes a first clamping part 131 and a first telescopic part 132. The first clamping part 131 is rotationally arranged on the rack 110, and the fixed end of the first telescopic part 132 is rotationally connected with the rack 110, and the piston end is rotationally connected with the first clamping part 131 to drive the first clamping part 131 to be connected with or separated from the ladle arm 120. During the extension or shortening of the piston end of the first telescopic part 132, the first clamping part 131 will be rotated around the connection point between the first clamping part 131 and the rack 110, so as to accurately clamp into the corresponding part on the ladle arm 120 to realize locking connection, or to be separated therefrom to realize separation, so as to control the rotation fulcrum of the ladle arm 120. After the first clamping part 131 is connected with the ladle arm 120, the first telescopic part 132 provides strong locking force for the first clamping part 131, which ensures the connection rigidity and reliability of the ladle arm 120 when bearing a large tilting torque. At the same time, its pure mechanical clamping mode has strong resistance to high temperature and dust interference, and realizes stable and precise remote locking and separation operation in harsh working conditions.

[0051] As preferred in the embodiment, the first telescopic part 132 is a hydraulic rod.

[0052] Specifically, as shown in the figure, Figure 5 The first locking rod 121 is limited by the first clamping groove 1311 when the first clamping part 131 is connected with the ladle arm 120. Through the mechanical hard connection of the mutual limiting and positioning of the first locking rod 121 and the first clamping groove 1311, an extremely stable and reliable rigid fulcrum is provided for the ladle arm 120 and the ladle 300 carried thereby, which can directly and efficiently bear a large tilting torque, thereby ensuring the stability of the position of the ladle 300 during pouring or slagging, greatly improving the safety of the operation, and the pure mechanical structure is simple and durable, and the maintenance cost is low.

[0053] As shown in the figure, Figure 6As shown, the second locking member 140 includes a second clamping portion 141 and a second telescopic portion 142. The second clamping portion 141 is rotationally arranged on the rack 110, and the fixed end of the second telescopic portion 142 is rotationally connected with the rack 110, and the piston end is rotationally connected with the second clamping portion 141 to drive the second clamping portion 141 to connect or separate with the tilter arm 120. During the extension or shortening of the piston end of the second telescopic portion 142, the second clamping portion 141 is pushed to rotate around the connecting point of the second clamping portion 141 and the rack 110, so that the second clamping portion 141 is accurately clamped into the corresponding part on the tilter arm 120 to realize locking connection or separation, so as to control the rotation of the tilter arm 120 around the fulcrum. After the second clamping portion 141 is connected with the tilter arm 120, the second telescopic portion 142 provides a strong locking force for the second clamping portion 141, ensuring the connection rigidity and reliability of the tilter arm 120 when bearing a large tilting torque. At the same time, the pure mechanical clamping mode has strong high-temperature resistance and dust interference resistance, and realizes stable and accurate remote locking and separation operation in harsh working conditions.

[0054] As preferred in the embodiment, the second telescopic portion 142 is a hydraulic rod.

[0055] Specifically, as shown in the drawings, Figure 6 The tilter arm 120 has a second locking rod 122, and the second clamping portion 141 has a second clamping groove 1411. When the second clamping portion 141 is connected with the tilter arm 120, the second locking rod 122 is limited and positioned with the second clamping groove 1411. Through the mechanical hard connection of the mutual limiting and positioning of the second locking rod 122 and the second clamping groove 1411, an extremely stable and reliable rigid fulcrum is provided for the tilter arm 120 and the ladle 300 carried thereby, which can directly and efficiently bear a large tilting torque, ensuring the stability of the position of the ladle 300 during pouring or slagging, greatly improving the safety of the operation, and the pure mechanical structure is simple and durable, and the maintenance cost is low.

[0056] As shown in the drawings, Figure 3 The tilter arm 120 has a mounting groove 123 for connecting with the ladle 300. The mounting groove 123 provided on the tilter arm 120 for connecting the ladle 300 provides a quick, accurate and stable positioning and mounting reference for the ladle 300. By embedding the corresponding structure (such as an ear shaft or a support) on the ladle 300 into the mounting groove 123, the quick centering of the two can be realized, and the tedious bolt connection is omitted, greatly improving the hoisting and positioning efficiency of the ladle 300.

[0057] As shown in the drawings, Figure 3As shown, the limiting member 160 is arranged on the rack 110 corresponding to the installation slot 123, and is used to stop the ladle 300. After the ladle 300 is fixed in the installation slot 123, the limiting member 160 and the corresponding structure (such as an ear shaft or a support) of the ladle 300 are mechanically interlocked, which ensures that when the ladle arm 120 bears a large tilting torque, the limiting member 160 can prevent the ladle 300 from falling out of the installation slot 123, thereby greatly enhancing the operation safety and reliability of the entire system under heavy load and high temperature working conditions.

[0058] As shown in Figure 3 , the limiting member 160 includes a third telescopic part 161 and a safety pin 162. The fixed end of the third telescopic part 161 is arranged on the rack 110, and the free end is movable with the safety pin 162, which is used to drive the safety pin 162 to move close to or away from the installation slot 123; the safety pin 162 is used to stop the ladle 300. By driving the safety pin 162 to move through the third telescopic part 161, the safety pin 162 can be accurately inserted into the installation slot 123 and mechanically stop the ladle 300, effectively preventing the ladle 300 from slipping during the tilting operation, thereby greatly enhancing the operation safety and stability of the equipment under heavy load and high temperature harsh working conditions. At the same time, this process does not require manual intervention, thereby improving the operation efficiency. At the same time, when the safety pin 162 moves away from the installation slot 123, the ladle 300 loses the interference of the safety pin 162, and can be quickly disassembled from the ladle arm 120.

[0059] As preferred in this embodiment, the third telescopic part 161 is a hydraulic rod.

[0060] As shown in Figure 1 , Figure 2 and Figure 4 , the driving member 150 includes a fourth telescopic part. The fixed end of the fourth telescopic part is rotationally connected with the rack 110, and the free end is rotationally connected with the ladle arm 120. The fourth telescopic part provides extremely smooth, powerful and controllable direct driving torque for bidirectional tilting of the ladle arm 120, so as to control the rotation of the ladle arm 120 around the first locking member 130 or the rotation around the second locking member 140.

[0061] As preferred in this embodiment, the fourth telescopic part is a hydraulic rod.

[0062] It should be noted that the two turning ladles 120 are arranged opposite to each other, and the ladle 300 is located between the two turning ladles 120, so that the double-point support and driving from both sides are simultaneously performed, thereby forming an extremely stable and balanced force system. The symmetrical layout can ensure that the huge tilting moment and load are evenly dispersed to the two turning ladles 120 and the whole frame 110, thereby completely avoiding problems such as distortion of the ladle, asynchronous tilting, and unbalanced load of the equipment caused by single-side stress, and greatly improving the stability, safety and reliability of the operation of the equipment. Meanwhile, the cooperative work of the two driving members 150 also provides greater driving torque and better control accuracy, thereby ensuring the precision and synchronization of the bidirectional tilting action of the ladle 300.

[0063] As shown in Figure 1 , Figure 2 and Figure 4 , the mobile platform 170 is provided with the pouring container 310 and / or the slagging container 320. The integration of the pouring container 310 and / or the slagging container 320 on the mobile platform enables the pouring process of receiving high-temperature molten metal and / or the slagging process of containing the skimmed molten slag to be directly completed on the mobile platform 170, thereby greatly simplifying the process flow and shortening the operation cycle.

[0064] Some embodiments of the present application also provide a bidirectional tilting type ladle turning machine control device 200 for controlling the bidirectional tilting type ladle turning machine 100, which comprises a controller, a detection unit and an execution unit.

[0065] As shown in Figure 7 , the detection unit is connected with the signal input end of the controller, and is used for detecting parameters of the first locking member 130, the second locking member 140 and the driving member 150. The controller can accurately determine whether each execution element is in place, the locking is reliable, and the load is abnormal according to the parameters of the first locking member 130, the second locking member 140 and the driving member 150, thereby not only being able to automatically coordinate the bidirectional tilting action flow of pouring and slagging, prevent misoperation, but also being able to give early warning or interlock shutdown to avoid major equipment accidents caused by locking failure, asynchrony or overload, thereby greatly improving the automation degree, safety and reliability of the operation.

[0066] Specifically, as shown in Figure 7As shown, the detection unit includes a first travel switch, a second travel switch, a displacement sensor, a pressure transmitter and a temperature transmitter; the first travel switch is used to detect whether the first locking member 130 is connected or separated from the tipping arm 120, the second travel switch is used to detect whether the second locking member 140 is connected or separated from the tipping arm 120, the displacement sensor is used to check the displacement stroke of the driving member 150, the pressure transmitter is used to monitor the hydraulic system pressure, and the temperature transmitter is used to monitor the hydraulic oil tank oil temperature. The first and second travel switches accurately judge the locking state, the displacement sensor real-time feedbacks the tipping position, the pressure transmitter monitors the system load, and the temperature transmitter guarantees the oil working condition, thereby constructing a comprehensive, multi-parameter real-time monitoring system, providing a comprehensive and reliable data basis for the controller, so that the system can not only accurately coordinate the automatic interlocking action of locking and tipping, eliminate mechanical interference, but also real-time evaluate the equipment health status, early warning and interlocking protection for overload, over-temperature, displacement abnormality and other faults, thereby greatly improving the automation level, operation safety and reliability of the whole tipping machine system under the harsh working conditions of high temperature, heavy load and frequent start-stop.

[0067] As shown in FIG. 1, the detection unit is connected with the signal output end of the controller, and is used to control the opening and closing of the first locking member 130, the second locking member 140 and the driving member 150. Figure 7 As shown, the execution unit is connected with the signal output end of the controller, and is used to control the opening and closing of the first locking member 130, the second locking member 140 and the driving member 150. The execution unit sequentially opens and closes the corresponding elements according to the key state signals such as the first locking member 130 has been reliably locked, the second locking member 140 has been completely separated, and the driving member 150 load is normal, which controls the opening and closing of the first locking member 130, the second locking member 140 and the driving member 150, fundamentally prevents the serious equipment accidents caused by misoperation and mechanical interference, and can realize the self-adaptive precise control of the tipping speed and torque by real-time monitoring the driving member 150 pressure, stroke and other parameters, even immediately execute the shutdown protection when overload and other abnormalities occur, thereby greatly improving the production safety and work efficiency.

[0068] Specifically, as shown in FIG. 1, the detection unit is connected with the signal output end of the controller, and is used to control the opening and closing of the first locking member 130, the second locking member 140 and the driving member 150. Figure 7As shown, the execution unit includes a hydraulic oil cooling pump start-stop control module, a hydraulic oil heater start-stop control module, a hydraulic pump start-stop control module, a hydraulic control valve block working state control module, and a hydraulic cylinder oil path on-off control module. By centrally controlling the cooling pump, the heater, the main hydraulic pump, the control valve block, and the oil path on-off, comprehensive and fine automatic management of the hydraulic system is realized, the corresponding modules can be intelligently started and stopped according to the real-time data such as oil temperature and pressure fed back by the detection unit, so that the hydraulic oil is always ensured to be within the optimal working temperature and viscosity range. This not only provides stable, reliable and rapid power output for the first locking member 130, the second locking member 140 and the driving member 150, ensures the accurate execution of the tilting and locking actions, but also greatly improves the efficiency and reliability of the hydraulic system itself, effectively avoids performance degradation, seal damage or equipment failure caused by excessively high or low oil temperature, and realizes efficient, stable and long-life operation of the entire power system under harsh working conditions.

[0069] As preferred in the embodiment, the controller is a Siemens PLC S7-1200.

[0070] The specific control method of the bidirectional overturning type billet tippler control device 200 is as follows:

[0071] Hydraulic oil heater start-stop control module control: the controller reads the hydraulic oil temperature data in real time, and when it is monitored that the temperature is lower than the set temperature, the hydraulic oil heater start-stop control module controls the heater to work, and stops heating when the set temperature is reached.

[0072] Hydraulic oil cooling pump start-stop control module: the controller reads the hydraulic oil temperature data in real time, and when it is monitored that the temperature is higher than the set temperature, the hydraulic oil cooling pump start-stop control module controls the cooling pump to work, and the cooling pump stops working when the temperature drops to the set range.

[0073] Hydraulic pump start-stop control module: according to the instructions issued by the controller, the hydraulic pump is started when the system needs to output power (such as executing tilting and locking actions) to provide the required flow and pressure for the system, and the pump is stopped when the system is in standby state.

[0074] Hydraulic control valve block working state control module: responsible for receiving controller signals and accurately adjusting the working state of core control valve blocks such as electro-hydraulic proportional valves or servo valves, controlling the flow direction of hydraulic oil, adjusting the flow of hydraulic oil, and stabilizing the working pressure of the system.

[0075] Hydraulic cylinder oil path on-off control module: when a certain oil cylinder (first telescopic part 132, second telescopic part 142, third telescopic part 161, fourth telescopic part) needs to act, it provides hydraulic power for it, and when the oil cylinder does not need to act or the system needs to be maintained, its oil path is reliably cut off and closed.

[0076] Pouring operation: the first travel switch detects that the first locking member 130 is connected with the ladle arm 120, the limiting member 160 abuts against the ladle 300, and the second locking member 140 is separated from the ladle arm 120, and the three conditions are met at the same time, so that the operation of the driving member 150 can be performed. During the pouring process, the displacement sensor detects the extension and retraction size of the hydraulic cylinder of the driving member 150 in real time, and at the same time, the unlocking of the first locking member 130 and the limiting member 160 and the locking operation of the second locking member 140 cannot be performed during pouring. The linear correspondence between the extension and retraction distance of the hydraulic cylinder of the driving member 150 and the tilting angle can be used to set the tilting angle, and the control functions such as pipeline overflow and reversing can be used to automatically pour.

[0077] Rake slag operation: the second travel switch detects that the second locking member 140 is connected with the ladle arm 120, the limiting member 160 abuts against the ladle 300, and the first locking member 130 is separated from the ladle arm 120, and the three conditions are met at the same time, so that the operation of the driving member 150 can be performed. During the pouring process, the displacement sensor detects the extension and retraction size of the hydraulic cylinder of the driving member 150 in real time, and at the same time, the unlocking of the second locking member 140 and the limiting member 160 and the locking operation of the first locking member 130 cannot be performed during pouring. The linear correspondence between the extension and retraction distance of the hydraulic cylinder of the driving member 150 and the tilting angle can be used to set the tilting angle, and the control functions such as pipeline overflow and reversing can be used to automatically pour.
