Description

[0001] This application belongs to the technical field of auxiliary equipment for zinc electrolysis, and specifically relates to a transfer trolley for a zinc electrolysis anode flattening machine. Background Art

[0002] Currently, in the wet-process zinc electrolysis industry, anode flattening machines are widely used. Their purpose is to clean and flatten the anode plates that have been used in the electrolytic cell for a certain period to reduce the occurrence of electric short circuits between the anode and cathode plates. The transfer trolley in the equipment is a key device, which is used to transfer the anode plates to be cleaned and filmed from the production line to the flattening machine for processing, and then send them back to the production line by the trolley after the processing is completed.

[0003] Transfer trolleys are quite common in industrial enterprises and usually use ordinary three-phase AC asynchronous motors to drive the movement. In order to supply electrical energy, power cables usually follow the trolley. In addition, to transmit electrical signals for some auxiliary functions, control cables are also required. During the operation of the trolley, it needs to start, stop, and change the running direction frequently, and also needs to adjust the speed, requiring fast speed response and accurate positioning.

[0004] In actual production, due to the fact that the trailing cables of the transfer trolley are in an acid mist environment, the bearings of the cable trolleys frequently get stuck after acid mist crystallization enters, resulting in unsmooth dragging of the trailing cables, and frequent problems such as cable breakage and deformation of the cable trolley brackets. After the problems occur, due to the large amount of maintenance work, the required maintenance time is long, and the downtime is long, which has a great impact on production organization. At the same time, replacing the trailing cables and cable trolleys also increases the maintenance cost. In addition, for some enterprises where the on-site environment is relatively special and trailing cables cannot be installed, the application of the flattening machine is restricted. It is necessary to eliminate the disadvantages of trailing cables and improve the motion control accuracy of the transfer trolley. Utility Model Content

[0027] like Figure 1 The zinc electrolysis anode flattening machine transfer trolley shown includes: a communication structure, a control module 4, a driving structure, a power supply structure and a loading structure.

[0028] The communication structure includes a trolley wireless communication module 5 and a host wireless communication module 6. The trolley wireless communication module 5 is installed on the trolley body. The trolley wireless communication module 5 is wirelessly connected to the host wireless communication module 6, and is used to transmit information such as the trolley walking direction instruction, the trolley walking speed setting, and the status signal to the flattening machine host. The trolley wireless communication module 5 and the host wireless communication module 6 are used in pairs, not limited to wireless bridges, WIFI switches, microwave communications, and laser communications. The communication rate is not limited to 2.4GHz, 4GHz, and 5GHz. The built-in communication physical interface is compatible with the trolley PLC control module 4. The communication protocol is not limited to PROFINET, MODBUS, MODBUS TCP, TCP / IP, PROFIBUS-DP, OPC, and S7.

[0029] The control module 4 is installed on the trolley body and connected to the trolley wireless communication module 5. The control module 4 processes the command signal of the leveling machine host received by the trolley wireless communication module 5 to control the low-voltage servo drive module 2 to perform forward and reverse drive and speed adjustment, and uploads the state of the trolley to the leveling machine host through the trolley wireless communication module 5. The control module 4 is provided with a communication physical interface compatible with the trolley wireless communication module 5, and the input and output points meet the low-voltage servo drive module 2 and other control requirements.

[0030] The driving structure includes a low-voltage servo drive module 2, a low-voltage servo motor 3, and a walking structure. The walking structure is connected to the output end of the low-voltage servo motor 3. The low-voltage servo motor 3 is connected to the low-voltage servo drive module 2. The power required for the trolley to travel is generated by the low-voltage servo drive module 2 driving the low-voltage servo motor 3. The low-voltage servo drive module 2 uses a DC power supply with a power supply voltage of 20-100V, and can drive a permanent magnet synchronous motor, a DC brushless motor, and a DC brush motor. The rated voltage of the low-voltage servo motor 3 is 24V-96V, and a permanent magnet synchronous motor, a DC brushless motor, and a DC brush motor can be used.

[0031] The power supply structure includes a battery pack 1 and an auxiliary power supply module 7. The auxiliary power supply module 7 is a high-frequency switching power supply, and its input voltage is the same as the output voltage of the battery pack 1. The output voltage of the auxiliary power supply module 7 is the same as the power supply voltage of the trolley wireless communication module 5 and the control module 4. After voltage transformation, the battery pack 1 supplies power to the control module 4 and the trolley wireless communication module 5. The battery pack 1 is connected to a charger 8, which is used to supplement the electrical energy after the battery pack 1 discharges. The charger 8 is matched with the battery pack 1 to meet the power required for charging and the charging control requirements. It is in a disconnected state during the normal operation of the zinc electrolysis anode flattening machine transfer trolley, and is connected to the battery pack 1 when the battery pack 1 needs to be charged.

[0032] The battery pack 1 can use nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries, lithium polymer batteries, lead-acid batteries, etc. Its output voltage is determined according to the power supply voltage of the actually selected low-voltage servo drive module 2, and its capacity is determined according to the load of the actual transfer trolley, the continuous working time, and the expected charging interval time.

[0033] As Figure 2 , Figure 3 shown, the loading structure includes a loading carriage 9 and a limiting frame 10. The limiting frame 10 is arranged according to the transportation needs of the anode plate 12 and is evenly distributed in the loading carriage 9. The distance between two adjacent limiting frames 10 is greater than the width of the anode plate 12. A number of limiting rings 11 for limiting the placement of the anode plate 12 are provided on the limiting frame 10. A set of limiting rings 11 are oppositely arranged on the adjacent limiting frame 10. Both ends of the anode plate 12 pass through a set of limiting rings 11 and are transported on the limiting frame 10 by being limited by the limiting rings 11. In order to prevent the limiting rings 11 from wearing the anode plate 12, an elastic cushion layer 111 is provided inside the limiting rings 11, as Figure 4 shown.

[0034] The usage process of the zinc electrolysis anode flattening machine transfer trolley:

[0035] When the battery pack 1 stores electrical energy normally, it supplies electrical energy to the low-voltage servo drive module 2. At this time, the low-voltage servo motor 3 waits for the drive of the low-voltage servo drive module 2. After the input side of the auxiliary power supply module 7 receives the power supply provided by the battery pack 1, it supplies the required power to the trolley PLC control module 4 and the trolley wireless communication module 5 through voltage transformation on the output side. The trolley PLC control module 4 and the trolley wireless communication module 5 enter the working state. When the flattening machine host PLC issues an instruction of "forward walking, walking speed 5m / min", the instruction is transmitted to the trolley wireless communication module 5 wirelessly through the host wireless communication module 6. The trolley wireless communication module 5 then transmits the instruction to the trolley PLC control module 4. After the trolley PLC control module 4 processes the instruction, it issues a forward drive signal and a pulse signal corresponding to "forward walking, walking speed 5m / min" to the low-voltage servo drive module 2. After receiving the signal, the low-voltage servo drive module 2 drives the low-voltage servo motor 3, and finally the transfer trolley walks in the positive direction at a speed of 5m / min.

[0036] When the battery pack 1 stores electrical energy normally, it supplies electrical energy to the low-voltage servo drive module 2. At this time, the low-voltage servo motor 3 waits for the drive of the low-voltage servo drive module 2. After the input side of the auxiliary power supply module 7 receives the power supply provided by the battery pack 1, it supplies the required power to the trolley PLC control module 4 and the trolley wireless communication module 5 through voltage transformation on the output side. The trolley PLC control module 4 and the trolley wireless communication module 5 enter the working state. When the flattening machine host PLC issues an instruction of "reverse walking, walking speed 0.5m / min", the instruction is transmitted to the trolley wireless communication module 5 wirelessly through the host wireless communication module 6. The trolley wireless communication module 5 then transmits the instruction to the trolley PLC control module 4. After the trolley PLC control module 4 processes the instruction, it issues a forward drive signal and a pulse signal corresponding to "reverse walking, walking speed 0.5m / min" to the low-voltage servo drive module 2. After receiving the signal, the low-voltage servo drive module 2 drives the low-voltage servo motor 3, and finally the transfer trolley walks in the reverse direction at a speed of 0.5m / min.

[0037] When the stored power of the battery pack 1 is low during the operation of the transfer trolley, the trolley PLC control module 4 monitors this state and sends the state signal to the trolley wireless communication module 5. The trolley wireless communication module 5 sends the state signal to the host wireless communication module 6 wirelessly, and then the host wireless communication module 6 sends it to the flattening machine host PLC. After receiving the signal that the power of the battery pack 1 of the transfer trolley is low, the flattening machine host PLC issues corresponding alarm information on the touch screen or the upper computer. After the operator confirms, the operation instruction for the transfer trolley to go to the charging position for charging is executed. It is transmitted wirelessly through the flattening machine host PLC and the host wireless communication module 6 to the trolley wireless communication module 5. The trolley wireless communication module 5 then transmits the instruction to the trolley PLC control module 4. After the trolley PLC control module 4 processes the instruction, it issues a reverse drive signal and a pulse signal corresponding to "going to the charging position" to the low-voltage servo drive module 2. After receiving the signal, the low-voltage servo drive module 2 drives the low-voltage servo motor 3. When the transfer trolley reaches the charging position, the flattening machine host PLC issues a stop command for the transfer trolley. According to the above instruction transmission steps, finally the transfer trolley stops at the charging position, and the charger 8 starts to connect and charge the battery pack 1.
