[0026] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0027] In the aluminum electrolysis industry, multi-functional overhead cranes are used in many scenarios. For example, they can be used to lift the anode busbar of the electrolytic cell. However, due to the lack of real-time monitoring during operation, the crane may experience brake failure and slippage, which could pose a significant safety hazard to the electrolysis workshop and even affect the electrolysis system, causing it to shut down for maintenance.
[0028] Regarding the above situation, firstly, please refer to [link / reference needed]. Figures 1-2 This application proposes an overhead crane 1 for an electrolysis workshop. The overhead crane 1 includes a main body 10, a first drive device 20, and a detection device 30. The electrolysis workshop can be divided into multiple work areas, and all electrolysis work in each work area is completed by one overhead crane 1, so that the production in the electrolysis workshop can proceed in an orderly manner. The overhead crane 1 can be used to transport electrolysis anode busbars and other heavy workpieces.
[0029] The main body 10 includes a support member 11 and a transport member 12 that are connected to each other; a first driving device 20 is disposed on the support member 11 and electrically connected to the transport member 12, and the first driving device 20 is used to drive the transport member 12 to move; a detection device 30 is disposed on the first driving device 20 and electrically connected to the first driving device 20, and the detection device 30 is used to detect the magnitude of the operating current of the first driving device 20.
[0030] Specifically, the support member 11 provides a base for the transport member 12 and the first drive device 20. The first drive device 20 can be connected to an external power source to drive the transport member 12 to lift and move the anode busbar or other heavy objects in the electrolysis workshop. The first drive device 20 can be a drive motor. During the operation of the first drive device 20, the detection device 30 can monitor its current in real time, thereby monitoring the operating status of the first drive device 20.
[0031] It should be noted that, in this embodiment of the application, a detection device 30 is set on the first drive device 20 to detect the operating current of the first drive device 20 in real time, so that the staff can intuitively view the specific current status of the first drive device 20. This allows for effective monitoring of the operating status of the first drive device 20 and the transport component 12. The detection device 30 can be set with a preset current value. When the detected current on the detection device 30 exceeds the preset current value, the staff can disconnect the power to the first drive device 20 for maintenance, thereby reducing the risk of the transport component 12 slipping or falling during transportation, reducing the sudden fall of the workpiece on the overhead crane 1, and improving the safety of the overhead crane 1 in the electrolysis workshop.
[0032] It should also be noted that the first drive device 20 has multiple power supply cables, and the detection device 30 can perform current detection on all multiple cables, thereby strengthening the current monitoring of the first drive device 20 and further improving the safety of the overhead crane 1.
[0033] The first drive device 20 includes a conical rotor motor with self-braking capability in the event of power failure. The braking device of the conical rotor motor consists of a brake spring fitted onto the motor rotor, a fan brake wheel, and a brake ring on the end cover. During operation, the air gap magnetic field of the conical rotor motor generates axial magnetic pull, compressing the brake spring and causing the fan brake wheel to disengage from the brake ring on the motor end cover, allowing the motor to rotate freely. When power is off, the axial magnetic pull disappears, and the rotor moves axially under the thrust of the brake spring, causing the fan brake wheel to press against the brake ring, generating friction and forcing the motor to stop quickly and securing the rotor. This prevents heavy workpieces lifted on the transport component 12 from falling, thus providing safety for workers in the electrolysis workshop. Additionally, in some embodiments of this application, the detection device 30 includes an ammeter to detect the current of the first drive device 20.
[0034] In some embodiments of this application, the overhead crane 1 further includes a controller (not shown in the figure), which is electrically connected to the detection device 30 and the first drive device 20. The controller is used to receive detection data from the detection device 30 and to send control signals to the first drive device 20.
[0035] Understandably, when the current detected by the detection device 30 exceeds the preset current, the detection device 30 can send the detected abnormal data to the controller. After receiving the abnormal data signal, the controller can immediately send a control signal to the first drive device 20, thereby controlling the first drive device 20 to cut off the power in time. In other words, when the operating current of the first drive device 20 is abnormal, the controller can cut off the power of the first drive device 20 at the first time, reducing the risk of the workpiece slipping or falling during the transportation of the transport component 12, and facilitating maintenance and inspection by the staff.
[0036] In some embodiments of this application, the overhead crane 1 further includes an indicator (not shown in the figure), which is disposed on the support member 11 and electrically connected to the detection device 30. The indicator is used to indicate the magnitude of the operating current of the first drive device 20.
[0037] Specifically, when the current detected by the detection device 30 exceeds the preset current, the indicator can immediately alert the staff that the current operating status of the first drive device 20 is abnormal, so that the staff can promptly disconnect the power to repair the crane 1, thereby further improving the safety performance of the crane 1.
[0038] Furthermore, in some embodiments of this application, the indicator includes an indicator light. When the current detected by the detection device 30 does not exceed the preset current, that is, when the first driving device 20 is in normal operation, the indicator light can turn green. When the current detected by the detection device 30 exceeds the preset current, that is, when the operating current of the first driving device 20 is abnormal, the indicator light can turn red to provide visual prompts to the staff.
[0039] Alternatively, the indicator may include a buzzer. When the current detected by the detection device 30 does not exceed the preset current, that is, when the first drive device 20 is in normal operation, the buzzer does not sound. When the current detected by the detection device 30 exceeds the preset current, that is, when the operating current of the first drive device 20 is abnormal, the buzzer sounds a warning sound to provide auditory information to the staff.
[0040] Alternatively, the indicator includes an indicator light and a buzzer. When the current detected by the detection device 30 does not exceed the preset current, that is, when the first drive device 20 is in normal operation, the indicator light turns green and the buzzer does not sound. When the current detected by the detection device 30 exceeds the preset current, that is, when the operating current of the first drive device 20 is abnormal, the indicator light turns red and the buzzer sounds a warning sound, so as to provide staff with warning information by combining visual and auditory senses.
[0041] Please see Figure 1 In some embodiments of this application, the main body 10 further includes a guide rail 13, the support member 11 is slidably connected to the guide rail 13 along the extension direction of the guide rail 13, and the transport member 12 is connected to the side of the support member 11 away from the guide rail 13. The transport member 12 can move on the guide rail 13 to transport the workpiece, thereby transporting the workpiece to different electrolytic cells.
[0042] Furthermore, in some embodiments of this application, the main body 10 also includes a second driving device (not shown in the figure), which is disposed on the support member 11 and electrically connected to the support member 11. The second driving device is used to drive the support member 11 to slide along the guide rail 13, wherein the second driving device can be a motor.
[0043] Secondly, this application also provides a crane unit, including multiple cranes 1 as described in any of the above embodiments. The multiple cranes 1 are arranged at intervals, and the multiple cranes 1 can move synchronously or each crane 1 can move individually.
[0044] In some embodiments of this application, the overhead crane unit also includes a display module (not shown in the figure). The display module is electrically connected to the detection devices 30 of the multiple overhead cranes 1. The display module is used to display the detection data of all detection devices 30, so that the staff can perform maintenance or replacement on each overhead crane 1 according to the display data on the display module.
