Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic aluminum anode casting systems, specifically to a remote wireless control system for electrolytic aluminum anode casting. Background Technology

[0002] In the production of electrolytic aluminum anodes and other workpieces, after the mold is assembled at the casting station, molten metal is transported to the casting station via a casting trolley for pouring. Currently, the casting trolley is controlled using the following methods:

[0003] 1) The casting trolley is equipped with a driver's cab, from which the operator controls the trolley's forward, backward, material receiving, and unloading actions. Because the operator is in a high-temperature environment and has prolonged visual contact with molten aluminum, the working environment is highly harmful to the human body and poses a significant risk to occupational health.

[0004] 2) A signal receiver is added to the casting trolley, and a separate fixed operating platform is set up on the ground. When the casting trolley is on the track outside the casting area, a local control signal is sent via a signal transmitter to directly control the operation of the casting trolley. When the casting trolley is on the track within the casting area, a signal is sent via a signal transmitter to the fixed operating platform, and the signal transmitting circuit of the fixed operating platform sends a remote control signal to control the operation of the casting trolley. However, because the operator cannot accurately observe the position of the casting trolley, there is a tendency for deviations between the casting trolley and the casting station, resulting in poor control accuracy. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to improve the working environment and reduce the damage to occupational health while ensuring the control accuracy of the casting trolley.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] This utility model provides a remote wireless control system for electrolytic aluminum anode casting, including a casting track, an operating room, and cameras. A casting trolley is installed on the casting track, and a casting station is installed below the casting track. Multiple cameras are arranged along the extension direction of the casting track, and the cameras can capture position images of the casting trolley and the casting station. The operating room is equipped with a fixed operating table and a display screen. The display screen is connected to the camera signal, and the fixed operating table is connected to a PLC control cabinet. The PLC control cabinet is wirelessly connected to the casting trolley.

[0008] The beneficial effects of this utility model are:

[0009] This invention utilizes multiple cameras to capture the position images of the casting trolley and projects them onto a display screen in the control room. When operators remotely control the casting trolley from within the control room, they can obtain the accurate relative position between the casting trolley and the casting station, improving the control precision and the casting working environment. A fixed operating platform provides operators with a fixed workstation, and seating and other facilities can be easily placed near the platform, ensuring good operating comfort. Control signals are centrally processed by a PLC control cabinet, and action commands are transmitted to the casting trolley wirelessly, achieving remote control.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the casting trolley is provided with at least two, and each pair of adjacent casting trolleys is provided with a position proximity sensor on the opposite side, and the position proximity sensor is connected to the PLC control cabinet for signal transmission.

[0012] The two casting trolleys can be used in one position and on standby, or they can be used simultaneously. When the two casting trolleys are too close to each other, the proximity sensor is triggered, and the trigger signal is transmitted to the PLC control cabinet. After receiving the signal, the PLC control cabinet issues a stop command to the two casting trolleys to avoid collision and improve safety.

[0013] Furthermore, it also includes an alarm, which is connected to the PLC control cabinet via signal.

[0014] When the two casting trolleys are too close together, the PLC control cabinet can trigger an alarm to alert the operators and improve operational safety.

[0015] Furthermore, at least one of the aforementioned alarms is installed in the control room.

[0016] This allows operators to receive alarms immediately, improving operational safety.

[0017] Furthermore, there are at least two casting stations, and each casting station is equipped with a camera above it.

[0018] This allows for the simultaneous use of two casting carriages, or for the molten metal from one casting carriage to be sequentially supplied to two casting stations, thereby improving casting efficiency.

[0019] Furthermore, the casting trolley is equipped with a trolley control cabinet and a casting hopper. The trolley control cabinet is equipped with a travel motor and a casting motor. The output shaft of the travel motor is driven and connected to a wheel, which is located on the upper side of the casting track. The casting hopper is equipped with rotating shafts on both sides, which are rotatably connected to the casting trolley. The output shaft of the casting motor is connected to the rotating shafts through chain drive or belt drive.

[0020] After receiving the action command from the PLC control cabinet, the trolley control cabinet can directly control the movement of the walking motor and / or the casting motor, which is convenient. When the casting motor is in motion, the forward or reverse rotation of the casting motor is transmitted to the rotating shaft, thereby driving the casting hopper to tilt or return to its original position. The structure is simple and the cost is low.

[0021] Furthermore, the upper side of the casting track is a rack structure, and the wheel is a gear that meshes with the upper side of the casting track.

[0022] To prevent the casting trolley from sliding along the casting track when it stops, and to facilitate precise control of the casting trolley's position.

[0023] Furthermore, the trolley control cabinet is also equipped with a signal transceiver, which is wirelessly connected to the PLC control cabinet, and the proximity sensor is connected to the signal transceiver.

[0024] It facilitates wireless remote control, is low-cost, and easy to control.

[0025] Furthermore, it also includes a switch, with all cameras connected to the switch via signal transmission, and the switch connected to the display screen via signal transmission.

[0026] It facilitates the centralized projection of camera images onto the display screen, offers high reliability, reduces the use of signal cables, and lowers costs.

[0027] Furthermore, the display screen is located directly above the fixed operating table.

[0028] When the operator is working on one side of the fixed control panel, they can look directly at the display screen, which makes it easy to obtain the real-time position information of the casting trolley and facilitates operation. Attached Figure Description

[0034] This utility model refers to Figure 1-2 .

[0035] This utility model provides a remote wireless control system for electrolytic aluminum anode casting, including a casting track 1, an operating room, and cameras 4. A casting trolley 3 is installed on the casting track 1, and a casting station 2 is installed below the casting track 1. Multiple cameras 4 are arranged along the extension direction of the casting track 1, and the cameras 4 can capture the position images of the casting trolley 3 and the casting station 2.

[0037] The control room can be located in an area with a good working environment, where operators work. During casting, images are captured by camera 4 and projected onto display screen 6, allowing operators to easily monitor the position of the casting trolley 3. This eliminates the need for operators to be directly in the high-temperature environment, ensuring accurate positioning of the casting trolley 3 and preventing significant positional deviations between the casting trolley 3 and the casting station 2. The fixed control panel 5 and PLC control cabinet 7 are mature existing technology products customized to meet functional requirements. The fixed control panel 5 integrates various buttons or joysticks, corresponding to the forward, backward, receiving, and unloading actions of the casting trolley 3. When the operator presses a button or moves a joystick, the trigger signal is transmitted to the PLC control cabinet 7. The central processing unit of the PLC control cabinet 7 processes the signal and outputs the corresponding action command to the casting trolley 3, thereby controlling its forward, backward, receiving, and unloading actions and achieving remote control.

[0038] Note: A signal transmitter can be installed in PLC control cabinet 7 to transmit action commands; a signal receiver can be installed in casting trolley 3 to receive action commands; a signal receiver can also be installed in PLC control cabinet 7 to receive other signals from casting trolley 3, such as the signal from position proximity sensor 8.

[0039] This invention utilizes multiple cameras 4 to capture position images of the casting trolley 3 and project them onto a display screen 6 in the control room. When operators remotely control the casting trolley 3 from within the control room, they can obtain the accurate relative position between the casting trolley 3 and the casting station 2, improving the control precision of the casting trolley 3 and enhancing the casting working environment. A fixed operating platform 5 provides a fixed operating position for the operator, and seating and other facilities can be easily placed near the platform, ensuring good operating comfort. The PLC control cabinet 7 centrally processes control signals and transmits action commands to the casting trolley 3 wirelessly, achieving remote control.

[0041] The two casting trolleys 3 can be used in one and on standby, or they can be used simultaneously. When the two casting trolleys 3 are too close, the proximity sensor 8 is triggered, and the trigger signal is transmitted to the PLC control cabinet 7. After receiving the signal, the PLC control cabinet 7 issues a stop command to the two casting trolleys 3 to avoid collision and improve safety.

[0042] Furthermore, it also includes an alarm 14, which is connected to the PLC control cabinet 7 via signal.

[0043] When the two casting trolleys 3 are too close together, the PLC control cabinet 7 can control the alarm 14 to be triggered, which can easily alert the operators and improve the safety of operation.

[0044] Furthermore, at least one of the aforementioned alarms 14 is installed in the control room.

[0045] This allows operators to receive alarms immediately, improving operational safety.

[0046] Furthermore, at least two casting stations 2 are provided, and each casting station 2 is equipped with a camera 4 above it.

[0047] This allows for the simultaneous use of two casting carriages 3, or for the molten metal from one casting carriage 3 to be sequentially supplied to two casting stations 2, thereby improving casting efficiency.

[0048] Furthermore, the casting trolley 3 is equipped with a trolley control cabinet 9 and a casting hopper 10. The trolley control cabinet 9 is equipped with a travel motor 11 and a casting motor 12. The output shaft of the travel motor 11 is connected to a wheel, which is located on the upper side of the casting track 1. The casting hopper 10 is equipped with rotating shafts on both sides, which are rotatably connected to the casting trolley 3. The output shaft of the casting motor 12 is connected to the rotating shaft through a chain drive or belt drive.

[0049] After receiving the action command from the PLC control cabinet 7, the trolley control cabinet 9 can directly control the movement of the walking motor 11 and / or the casting motor 12, which is convenient. When the casting motor 12 moves, the forward or reverse movement of the casting motor 12 is transmitted to the rotating shaft, thereby driving the casting hopper 10 to tilt or return to its original position. The structure is simple and the cost is low.

[0050] Furthermore, the upper side of the casting track 1 is a rack structure, and the wheel is a gear that meshes with the upper side of the casting track 1.

[0051] To prevent the casting trolley 3 from sliding along the casting track 1 when it stops, and to facilitate precise control of the position of the casting trolley 3.

[0052] Furthermore, the trolley control cabinet 9 is also equipped with a signal transceiver 13, which is wirelessly connected to the PLC control cabinet 7, and the proximity sensor 8 is signal connected to the signal transceiver 13.

[0053] Note: The signal transceiver 13 can be a router, PLC-I / O module, etc. The signal transceiver 13, the travel motor 11, and the casting motor 12 are all located inside the trolley control cabinet 9, and are connected to the trolley control cabinet 9 by default. The trolley control cabinet 9 is a mature existing technology product customized according to functional requirements.

[0054] It facilitates wireless remote control, is low-cost, and easy to control.

[0055] Furthermore, it also includes a switch 15, with each of the cameras 4 connected to the switch 15 via signal, and the switch 15 connected to the display screen 6 via signal.
