[0002] In the aluminum electrolysis production process, an overhead crane is a crucial piece of equipment, responsible for precisely feeding anode assemblies into the electrolytic cell to maintain the continuity and efficiency of the electrolysis process. Traditional aluminum electrolysis overhead crane designs often utilize a single-anode mechanism, meaning they can only process one anode at a time. However, with advances in aluminum electrolysis technology and rising production efficiency requirements, dual-anode mechanisms have gradually gained adoption. This design allows the crane to process two anodes simultaneously in a single operation, significantly improving production efficiency. However, the use of dual-anode mechanisms also presents new technical challenges. Because both anodes must be precisely positioned simultaneously in the electrolytic cell, the crane's control system must possess a high degree of precision and synchronization.

[0003] In existing technologies, although the lifting and lowering of the dual anodes can be achieved through simple mechanical linkage or independent control systems, these methods often have problems such as insufficient precision and poor synchronization, which can easily lead to inaccurate positioning of the anodes in the electrolytic cell, affecting electrolysis efficiency and product quality, and may even cause damage to the overhead crane and equipment.

DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Example 1

[0029] Reference Figure 1 、 Figure 2 A synchronization system for a dual-anode mechanism of an aluminum electrolysis overhead crane includes: a lifting device 1, a displacement measuring device 2, and a control module 3. The displacement measuring device 2 is arranged on the lifting device 1, and both the lifting device 1 and the displacement measuring device 2 are connected to the control module 3; wherein the lifting device 1 is used to adjust the height of the dual-anode mechanism; the displacement measuring device 2 is used to measure the height of the dual-anode mechanism; and the control module 3 is used to control the lifting device 1 to adjust the height of the dual-anode mechanism according to data fed back by the displacement measuring device, and to keep the heights of the dual-anode mechanisms synchronized.

[0030] In this embodiment, the lifting device 1 includes a first lifting mechanism 101 and a second lifting mechanism 102. The first lifting mechanism 101 and the second lifting mechanism 102 are respectively connected to the first anode mechanism 103 and the second anode mechanism 104 of the dual anode mechanism. The first lifting mechanism 101 and the second lifting mechanism 102 are respectively responsible for driving the first anode mechanism 103 and the second anode mechanism 104 of the overhead crane to move up and down. The first lifting mechanism 101 and the second lifting mechanism 102 can be lifting mechanisms driven by hydraulic cylinders.

[0031] In this embodiment, the displacement measurement device 2 includes: a first reference assembly 201, a second reference assembly 202, a first measuring assembly 203, and a second measuring assembly 204. The first reference assembly 201 and the second reference assembly 202 are respectively disposed at corresponding positions on the first lifting mechanism 101 and the second lifting mechanism 102. The first measuring assembly 203 and the second measuring assembly 204 are respectively disposed at corresponding positions on the first lifting mechanism 101 and the second lifting mechanism 102. The first reference assembly 201 and the second reference assembly 202 may be laser rangefinders, and the first measuring assembly 203 and the second measuring assembly 204 may be laser rangefinders. The first reference assembly 201 and the second reference assembly 202 serve as reference points for laser rangefinders. The first measuring assembly 203 and the second measuring assembly 204 are used to monitor the height changes of the first anode mechanism 103 and the second anode mechanism 104 in real time during the lifting process.

[0032] In this embodiment, the initial spacing between the first measuring assembly 203 and the first reference assembly 201 is equal to the initial spacing between the second measuring assembly 204 and the second reference assembly 202. The reference planes of the first reference assembly 201 and the second reference assembly 202 may be different. The first measuring assembly 203 and the second measuring assembly 204 monitor the first spacing between the first measuring assembly 203 and the first reference assembly 201 and the second spacing between the second measuring assembly 204 and the second reference assembly 202 in real time. The program built into the control module 3 analyzes and compares the difference between the first spacing and the second spacing. If the height difference exceeds a preset synchronization accuracy, for example, a preset accuracy of 5 mm, the lifting device 1 is controlled to adjust the height of the first anode mechanism 103 and the second anode mechanism 104 to maintain height synchronization with the second anode mechanism 103 and the second anode mechanism 104.

[0033] In this embodiment, the control module 3 has a built-in programmable logic controller 301; wherein, the programmable logic controller 301 is used to receive the height difference data of the dual anode mechanism during the lifting process fed back by the displacement measuring device 2, and control the first lifting mechanism 101 and the second lifting mechanism 102 to adjust the height of the first anode mechanism 103 and the second anode mechanism 104 according to the height difference data, and keep the height of the first anode mechanism 103 and the second anode mechanism 104 synchronized.

[0034] Example 2

[0035] Based on Example 1, in this embodiment, the initial heights of the first reference assembly 201 and the second reference assembly 202 are the same. The first reference assembly 201 and the second reference assembly 202 are fixedly mounted at corresponding positions on the first lifting mechanism 101 and the second lifting mechanism 102, respectively, ensuring that their initial heights are completely consistent. This can be achieved by using a precision measuring tool (such as a laser rangefinder or a level). The first measuring assembly 203 is mounted on the first lifting mechanism 101 so that it can accurately measure the distance to the first reference assembly 201. Similarly, the second measuring assembly 204 is mounted on the second lifting mechanism 102 to measure the distance to the second reference assembly 202. After installation, the system needs to be calibrated to ensure alignment between the laser rangefinder and the laser rangefinder plate, and to adjust the sensitivity of the laser rangefinder to ensure measurement accuracy. Because the initial heights of the first reference assembly 201 and the second reference assembly 202 are the same, the laser rangefinder has higher accuracy during measurement. This helps reduce measurement errors caused by inconsistent reference surfaces. A unified reference surface helps maintain the stability of the system, reduces the impact of external factors (such as vibration, temperature changes, etc.) on the measurement results, and can further improve the synchronization performance of the dual anode mechanism to ensure the smooth progress of the anode replacement process.

[0036] Example 3

[0037] Based on Example 1 and Example 2, refer to Figure 3 In this embodiment, an alarm module 4 is further included, and the alarm module 4 is connected to the control module 3; wherein the alarm module 4 is used to send an alarm signal when the lifting synchronization value of the dual anode mechanism exceeds the preset range value. An alarm signal is sent when the lifting synchronization value of the dual anode mechanism exceeds the preset range value. The preset range value (i.e., the synchronization accuracy threshold) can be set through the user interaction module 5, for example, set to ±5mm. When the control module 3 monitors that the height difference between the first anode mechanism 103 and the second anode mechanism 104 exceeds this threshold through the displacement measuring device 2, the alarm module 4 will be activated. The alarm module 4 can send out various types of alarm signals, including but not limited to:

[0038] Sound and light alarm: Through the buzzer and indicator light installed on the overhead crane, when the synchronization value is out of range, the buzzer will sound an alarm and the indicator light will flash to attract the attention of the operator.

[0039] Screen display alarm: The alarm information is displayed on the display screen of the user interaction module 5 in a striking manner, such as red font or flashing, including the specific value and occurrence time of exceeding the synchronization accuracy.

[0040] Remote alarm: Alarm information is sent to the remote monitoring center or the mobile device of the relevant person in charge through wireless network or wired communication so that timely response measures can be taken.

[0041] In this embodiment, the control module 3 has a built-in storage unit 302 ; wherein the storage unit 302 is used to store the height difference data and adjustment records during the lifting process of the dual anode mechanism.

[0042] This embodiment also includes a user interaction module 5, which is connected to the control module 3. The user interaction module 5 is used to set the synchronization accuracy value, view historical data, and adjust the record. The user interaction module 5 adopts a graphical user interface (GUI) design to ensure that users can operate the system intuitively and conveniently. The interface design includes the following main parts:

[0043] Main menu: provides the main function options of the system, such as parameter setting, data viewing, alarm recording, etc.

[0044] Parameter setting area: allows users to set the synchronization accuracy value. Users can enter a specific value in the input box, and the system will perform height synchronization control based on the value.

[0045] Data Viewing Area: Displays the height difference data and adjustment records of the dual anode mechanism during the lifting process. The data can be presented in the form of charts or tables to facilitate data analysis.

[0046] Alarm information area: When the lifting and lowering synchronization value of the dual anode mechanism exceeds the preset range, the alarm information is displayed and the user is allowed to view detailed alarm records.

[0047] In this embodiment, the user enters a synchronization accuracy value through the interface. The system receives this value and stores it in the storage unit 302 of the control module 3. The control module 3 will refer to this value to make decisions and adjustments during subsequent height synchronization control. The user can also use the interface to view historical data or adjust the record. The system reads relevant data from the storage unit 302 and displays it to the user on the interface. When the alarm module 4 issues an alarm signal, the user interaction module 5 displays the alarm information on the interface and allows the user to view detailed alarm records. The user can also confirm or cancel the alarm through the interface.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
