[0033] Please refer to Figure 1 and Figure 2 , the charger module 11 of the utility model can output the power supply voltage to the subsequent equipment. Thus, the subsequent equipment can be started and work normally based on the power supply voltage. And the first carbon-based capacitor module 12 can adjust the power supply voltage so that the power supply voltage output to the subsequent equipment is more stable, so that the subsequent equipment can maintain a stable working state. Thus, the subsequent equipment can be started and work normally based on the power supply voltage. Because the tire crane power supply drive system 10 first supplies a small current through the charger module 11, and then supplies a large current through the charger module 11, the tire crane power supply drive system 10 can start the subsequent equipment smoothly. The first carbon-based capacitor module can adjust the power supply voltage through the switch module, so that the power supply voltage output to the subsequent equipment is more stable, so that the subsequent equipment can maintain a stable working state for a long time. And, because the first carbon-based capacitor module 12 first adjusts the power supply voltage through a small current circuit, and then adjusts the power supply voltage through a large current circuit through the charger module, the first carbon-based capacitor module 12 can adjust the power supply voltage smoothly.

[0034] Please refer to Figure 1 and Figure 2When the charger module 11 inputs voltage, the charger module 11 generates a supply voltage based on the three-phase AC power of 380V. The charger control module 16 can receive the supply voltage, and then turn on the charger low-current relay 3SJB. The charger control module 16 generates a first start signal based on the supply voltage, and the control end of the charger low-current contactor DJ3B receives the first start signal. The charger low-current contactor DJ3B is turned on, so that the charger low-current circuit 131 is turned on. After the charger low-current relay 3SJB is turned on, the first start time is delayed, and the charger high-current relay 3SJA is turned on. The charger control module 16 generates a second start signal based on the supply voltage, and the control end of the charger high-current contactor DJ3A receives the second start signal, and the charger high-current contactor DJ3A is turned on. As a result, the charger high-current circuit 132 is turned on, and the charger module 11 transmits the supply voltage to the output module 14 through the charger high-current circuit 132, and the output module 14 outputs the supply voltage to the subsequent device.

[0035] Next, the first start switch SA1-1 is closed, and the first drive battery 1E1 is used to output the battery voltage to the first low-current relay 1SJB. Then, the first low-current relay 1SJB is turned on, and the first carbon-based capacitor control module 17 can generate a third start signal based on the battery voltage. The control end of the first low-current contactor DJ1B receives the third start signal, and the first low-current contactor DJ1 B is turned on, so that the first carbon-based capacitor low-current circuit 133 is turned on.

[0036] After the first low-current contactor DJ1 B is turned on, the second opening time is delayed, and the first high-current relay 1SJA is turned on. The first carbon-based capacitor control module 17 outputs a fourth opening signal, the control end of the first high-current contactor DJ1A receives the fourth opening signal, the first high-current contactor DJ1A is turned on, and thus the first carbon-based capacitor high-current circuit 134 is turned on. Thus, the first carbon-based capacitor module 12 is connected to the power supply circuit of the tire crane equipment, and the first carbon-based capacitor module 12 can adjust the power supply voltage. At the same time, the second start switch SA1-2 is closed, and the first drive battery 1E1 is used to output the battery voltage to the first carbon-based capacitor relay 10DJ1. The first carbon-based capacitor relay 10DJ1 is turned on, and the first carbon-based capacitor module 12 outputs voltage to the first low-current relay 1SJB, the first high-current relay 1SJA and the first drive battery 1E1. The first driving battery 1E1 can store the electric energy output by the first carbon-based capacitor module 12. Therefore, the first driving battery 1E1 always has enough power to drive the first small current relay 1SJB, the first large current relay 1SJA and the first carbon-based capacitor relay 10DJ1.

[0037] Please refer to Figure 1 and Figure 2When the tire crane power drive system 10 is turned off, the charger high current relay 3SJA is disconnected. The charger control module 16 outputs a first disconnection signal, the control end of the charger high current contactor DJ3A receives the first disconnection signal, the charger high current contactor DJ3A is disconnected, and the charger high current circuit 132 is disconnected. At this time, the charger module 11 stops outputting the power supply voltage to the output module 14. The first carbon-based capacitor 121 outputs the voltage to the output module 14.

[0038] After the charger high current relay 3SJA is disconnected, the first disconnection time is delayed, and the charger low current relay 3SJB is disconnected. The charger control module 16 outputs a second disconnection signal, and the control end of the charger low current contactor DJ3B receives the second disconnection signal. The charger low current contactor DJ3B is disconnected, so that the charger low current circuit 131 is disconnected.

[0039] When the tire crane power drive system 10 is turned off, the first high current relay 1SJA is disconnected. The first carbon-based capacitor control module 17 outputs a third disconnection signal, and the control end of the first high current contactor DJ1A receives the third disconnection signal. The first high current contactor DJ1A is disconnected, so that the first carbon-based capacitor high current circuit 134 is disconnected. At the same time, the second start switch SA1-2 is disconnected, and the first carbon-based capacitor relay 10DJ1 is disconnected.

[0040] After the first high current relay 1SJA is disconnected, the second disconnection time is delayed, and the first start switch SA1-1 is disconnected. The first low current relay 1SJB is disconnected, and the first carbon-based capacitor control module 17 outputs a fourth disconnection signal. The control end of the first low current contactor DJ1 B receives the fourth disconnection signal, and the first low current contactor DJ1 B is disconnected, so that the first carbon-based capacitor low current circuit 133 is disconnected.

[0041] Please refer to Figure 1 and Figure 2In the tire crane power drive system 10 of the utility model, the charger control module 16 and the first carbon-based capacitor control module 17 are separated. Therefore, the charger module 11 and the first carbon-based capacitor module 12 can be turned off independently. That is, when the tire crane power drive system 10 is turned off, the charger module 11 can be turned off first, and then the first carbon-based capacitor module 12. Or, the first carbon-based capacitor module 12 is turned off first, and then the charger module 11 is turned off. Thus, the shutdown of the charger module 11 and the first carbon-based capacitor module 12 will not affect each other. Therefore, even if a circuit failure occurs in the charger module 11, the first carbon-based capacitor control module 17 can also output voltage to the subsequent equipment normally, so that the subsequent equipment can continue to work for a period of time. When a power grid failure occurs, the charger module 11 fails to output the power supply voltage, and the first carbon-based capacitor control module 17 and the first carbon-based capacitor module also maintain power supply and control for the subsequent equipment, which can effectively avoid the subsequent equipment from being in danger due to sudden power failure.

[0042] In addition, the charger control module 16 is started after receiving the power supply voltage, and the charger high current circuit 132 and the charger low current circuit 131 are turned on under the control of the charger control module 16. Moreover, the first carbon-based capacitor control module 17 is started when the first driving battery 1E1 supplies power or the first carbon-based capacitor module 12 drives it. Since the output of the charger module 11 is directly controlled by three-phase alternating current and is not controlled by the carbon-based capacitor control module, even if the first driving battery 1E1 is out of power or the first carbon-based capacitor 121 cannot work normally, the charger module 11 can still output normally. That is, if a circuit failure occurs in the first carbon-based capacitor control module 17, the charger module 11 can also output the power supply voltage normally to the subsequent equipment. The charger module 11 and the carbon-based capacitor module are controlled by different control modules respectively, and the entire circuit cannot be output due to the failure of the carbon-based capacitor control module or the carbon-based capacitor module. The working efficiency of the tire crane power drive system 10 is effectively improved.

[0043] Please refer to Figure 1 and Figure 2, the first carbon-based capacitor control module 17 also includes a first detection control unit (not shown in the figure), and the first detection control unit outputs a first cut-off signal and a second cut-off signal based on the voltage value of the first carbon-based capacitor 121. The first carbon-based capacitor control module 17 also includes a first control relay 6ZJ1-2 and a second control relay 7ZJ1-2. One end of the first detection control unit is connected to the first carbon-based capacitor 121, and the other end of the first detection control unit is connected to the control end of the first control relay 6ZJ1-2 and the control end of the second control relay 7ZJ1-2. The input end of the first control relay 6ZJ1-2 is connected to the first carbon-based capacitor module 12 and the first driving battery 1E1, the output end of the first control relay 6ZJ1-2 is connected to the input end of the second control relay 7ZJ1-2, and the output end of the second control relay 7ZJ1-2 is connected to the control end of the first small current relay 1SJB and the control end of the first large current relay 1SJA.

[0044] Please refer to Figure 1 and Figure 2 , when the voltage value of the first carbon-based capacitor 121 is less than the first set voltage, the first detection control unit outputs a first cut-off signal. The first control relay 6ZJ1-2 is disconnected based on the first cut-off signal, and the control end of the first low-current relay 1SJB and the control end of the first high-current relay 1SJA do not receive voltage, and the first low-current relay 1SJB and the first high-current relay 1SJA are both disconnected. Then the first low-current contactor DJ1 B and the first high-current contactor DJ1A are both disconnected, and the first carbon-based capacitor module 12 is in a disconnected state.

[0045] Please refer to Figure 1 and Figure 2 , when the voltage value of the first carbon-based capacitor 121 is greater than the second set voltage, the first detection control unit outputs a second cut-off signal. The second control relay 7ZJ1-2 is disconnected based on the second cut-off signal, and the control end of the first low-current relay 1SJB and the control end of the first high-current relay 1SJA do not receive voltage. The first low-current relay 1SJB and the first high-current relay 1SJA are both disconnected, and then the first low-current contactor DJ1 B and the first high-current contactor DJ1A are both disconnected, and the first carbon-based capacitor module 12 is in a disconnected state.

[0046] Please refer to Figure 1 and Figure 2, the first carbon-based capacitor control module 17 also includes a buzzer H1, a switch 6ZJ1-1, and a switch 7ZJ1-1. One end of the switch 6ZJ1-1 is connected to the first carbon-based capacitor 121 or the first drive battery 1E1, and the other end of the switch 6ZJ1-1 is connected to the buzzer H1, and the switch 7ZJ1-1 is connected in parallel with the switch 6ZJ1-1. When the voltage value of the first carbon-based capacitor 121 is greater than the third set voltage, the switch 6ZJ1-1 or the switch 7ZJ1-1 will be turned on. The first drive battery 1E1 will drive the buzzer H1 to make a sound, and the tire crane power drive system 10 will send an alarm signal. Among them, the third set voltage is 552V.

[0047] Please refer to Figure 1 and Figure 2 The tire crane power supply drive system 10 also includes a second carbon-based capacitor module 18 and a second carbon-based capacitor control module 19. The switch module 13 includes a second carbon-based capacitor small current circuit 135 and a second carbon-based capacitor large current circuit 136. The second carbon-based capacitor module 18 is used to adjust the power supply voltage. The second carbon-based capacitor control module 19 is connected to the second carbon-based capacitor module 18, and the second carbon-based capacitor control module 19 is used to control the conduction and disconnection of the second carbon-based capacitor small current circuit 135 and the second carbon-based capacitor large current circuit 136. Among them, the circuit structure of the second carbon-based capacitor module 18 is the same as the circuit structure of the first carbon-based capacitor module 12. The circuit structure of the second carbon-based capacitor control module 19 is the same as the circuit structure of the first carbon-based capacitor control module 17. In addition, the method for controlling the on-off of the circuit by the second carbon-based capacitor control module 19 is the same as the method for controlling the on-off of the first carbon-based capacitor control module 17. When the first carbon-based capacitor module 12 is damaged, the second carbon-based capacitor module 18 can replace the function of the first carbon-based capacitor module 12, so that the second carbon-based capacitor module 18 can adjust the power supply voltage. Therefore, even if the first carbon-based capacitor module 12 is damaged, the tire crane power drive system 10 will not stop working, effectively improving the working efficiency of the tire crane power drive system 10. Moreover, the first carbon-based capacitor module 12 and the second carbon-based capacitor module 18 can also adjust the power supply voltage at the same time, so that the charger module 11 can provide more stable power supply to the subsequent equipment.

[0048] The working principle of the utility model is as follows: when the tire crane power drive system 10 is turned on, the power supply switch K1 of the charger module 11 is closed, and the charger module 11 generates a power supply voltage based on the 380V three-phase AC power input from the power grid. Next, close the switch 3SA and the switch 3SA1, so that the charger low-current relay 3SJB and the charger high-current relay 3SJA can receive the power supply voltage. Subsequently, the charger low-current relay 3SJB is turned on, and the charger control module 16 can generate a first start signal based on the power supply voltage. Then, the control end of the charger low-current contactor DJ3B receives the first start signal. The charger low-current contactor DJ3B is turned on based on the first start signal, and then the charger low-current circuit 131 is turned on.

[0049] After the charger low current relay 3SJB is turned on, the first opening time is delayed. The charger high current relay 3SJA is turned on, and the charger control module 16 can generate a second opening signal based on the power supply voltage. The control end of the charger high current contactor DJ3A receives the second opening signal. The charger high current contactor DJ3A can be turned on based on the second opening signal, and then the charger high current circuit 132 is turned on. The charger module 11 transmits the power supply voltage to the output module 14 through the charger high current circuit 132, and the output module 14 outputs the power supply voltage to the subsequent device.

[0050] Subsequently, the first fuse switch FU1+ and the second fuse switch FU1- are closed, and then the first carbon-based capacitor 121 can be connected to the circuit. At the same time, the first start switch SA1-1 is closed, and the first drive battery 1E1 outputs the battery voltage to the first small current relay 1SJB. Next, the first control relay 6ZJ1-2, the second control relay 7ZJ1-2 and the switch 1SA1-1 are closed, so that the first small current relay 1SJB and the first large current relay 1SJA can receive the battery voltage. The first small current relay 1SJB is turned on, and the first carbon-based capacitor control module 17 can generate a third start signal based on the battery voltage. The control end of the first small current contactor DJ1 B receives the third start signal, and the first small current contactor DJ1 B can be turned on based on the third start signal, and then the first carbon-based capacitor small current circuit 133 is turned on.

[0051] After the charger high-current relay 3SJA is turned on, the second turn-on time is delayed. The first high-current relay 1SJA is turned on, and the first carbon-based capacitor control module 17 generates a fourth turn-on signal based on the battery voltage. The control end of the first high-current contactor DJ1A receives the fourth turn-on signal, and the first high-current contactor DJ1A can be turned on based on the fourth turn-on signal, so that the first carbon-based capacitor high-current circuit 134 is turned on, and the first carbon-based capacitor module 12 can be used to adjust the supply voltage. At the same time, the second start switch SA1-2 and the third fuse switch K2 are closed, and the first drive battery 1E1 outputs the battery voltage to the first carbon-based capacitor relay 10DJ1. Then the first carbon-based capacitor relay 10DJ1 is turned on, and the first carbon-based capacitor module 12 can output voltage to the first small-current relay 1SJB, the first large-current relay 1SJA and the first drive battery 1E1, and the first drive battery 1E1 can store the electric energy output by the first carbon-based capacitor module 12.

[0052] When the tire crane power drive system 10 is turned off, the charger high-current relay 3SJA is disconnected, and the charger control module 16 outputs a first disconnection signal. The control end of the charger high-current contactor DJ3A receives the first disconnection signal, and the charger high-current contactor DJ3A can be disconnected based on the first disconnection signal, so that the charger high-current circuit 132 is disconnected. After the charger high-current relay 3SJA is disconnected, the first disconnection time is delayed. The charger low-current relay 3SJB is disconnected, and the charger control module 16 outputs a second disconnection signal. The control end of the charger low-current contactor DJ3B receives the second disconnection signal, and the charger low-current contactor DJ3B can be disconnected based on the second disconnection signal, so that the charger low-current circuit 131 is disconnected. Then, the switch 3SA, the switch 3SA1 and the power supply switch K1 are disconnected, and the charger module 11 stops inputting three-phase AC power, thereby shutting down the charger module 11.

[0053] When the tire crane power drive system 10 is turned off, the first high current relay 1SJA is disconnected. The first carbon-based capacitor control module 17 outputs a third disconnection signal, and the control end of the first high current contactor DJ1A receives the third disconnection signal. The first high current contactor DJ1A can be disconnected based on the third disconnection signal, so that the first carbon-based capacitor high current circuit 134 is disconnected. At the same time, the second start switch SA1-2 and the third fuse switch K2 are disconnected. Therefore, the first carbon-based capacitor relay 10DJ1 does not receive the battery voltage, and the first carbon-based capacitor relay 10DJ1 is disconnected.

[0054] After the first high current relay 1SJA is disconnected, the second disconnection time is delayed. The first start switch SA1-1 is disconnected to turn off the first drive battery 1E1. The first small current relay 1SJB does not receive the battery voltage, so the first small current relay 1SJB is disconnected, and the first carbon-based capacitor control module 17 outputs a fourth disconnection signal. The control end of the first small current contactor DJ1 B receives the fourth disconnection signal, and the first small current contactor DJ1 B can be disconnected based on the fourth disconnection signal, so that the first carbon-based capacitor small current circuit 133 is disconnected. And, the first control relay 6ZJ1-2, the second control relay 7ZJ1-2 and the switch 1SA1-1 are turned off. Subsequently, the first fuse switch FU1+ and the second fuse switch FU1- are turned off, thereby turning off the first carbon-based capacitor 121.

[0055] In the tire crane power drive system 10 of the utility model, the charger control module 16 and the first carbon-based capacitor control module 17 are separated. Therefore, the charger module 11 and the first carbon-based capacitor module 12 can be turned off independently. That is, when the tire crane power drive system 10 is turned off, the charger module 11 can be turned off first, and then the first carbon-based capacitor module 12. Or, the first carbon-based capacitor module 12 is turned off first, and then the charger module 11 is turned off. Thus, the shutdown of the charger module 11 and the first carbon-based capacitor module 12 will not affect each other. After the charger module 11 is turned off, the first carbon-based capacitor 121 can still output voltage to the output module 14. After the first carbon-based capacitor 121 is turned off, the charger module 11 can also output voltage to the output module 14. When the voltage value of the first carbon-based capacitor 121 is less than the first set voltage, the first detection control unit outputs a first cut-off signal. The first control relay 6ZJ1-2 is disconnected based on the first cut-off signal, and the control end of the first low-current relay 1SJB and the control end of the first high-current relay 1SJA do not receive the battery voltage of the first drive battery, and the first low-current relay 1SJB and the first high-current relay 1SJA are both disconnected. Because the control end of the first low-current contactor DJ1 B is connected to the first low-current relay 1SJB, and the control end of the first high-current contactor DJ1A is connected to the first high-current relay 1SJA, the first low-current contactor DJ1 B and the first high-current contactor DJ1A are both disconnected, and the first carbon-based capacitor module 12 is in a disconnected state.

[0056] When the voltage value of the first carbon-based capacitor 121 is greater than the second set voltage, the first detection control unit outputs a second cut-off signal. The second control relay 7ZJ1-2 is disconnected based on the second cut-off signal, and the control end of the first small current relay 1SJB and the control end of the first large current relay 1SJA do not receive the battery voltage of the first drive battery, and the first small current relay 1SJB and the first large current relay 1SJA are both disconnected. Because the control end of the first small current contactor DJ1 B is connected to the first small current relay 1SJB, and the control end of the first large current contactor DJ1A is connected to the first large current relay 1SJA, the first small current contactor DJ1 B and the first large current contactor DJ1A are both disconnected, and the first carbon-based capacitor module 12 is in a disconnected state.

[0057] In the tire crane power drive system of the utility model, even if the charger module 11 has a circuit failure, the first carbon-based capacitor control module 17 can still output voltage to the subsequent equipment normally, so that the subsequent equipment can continue to work for a period of time. When the power grid fails, the charger module 11 fails to output the power supply voltage, and the first carbon-based capacitor control module 17 and the first carbon-based capacitor module also maintain power supply and control to the subsequent equipment, which can effectively avoid the subsequent equipment from being in danger due to sudden power failure.

[0058] In addition, the charger control module 16 is started after receiving the power supply voltage, and the charger high current circuit 132 and the charger low current circuit 131 are turned on under the control of the charger control module 16. Moreover, the first carbon-based capacitor control module 17 is started when the first driving battery 1E1 supplies power or the first carbon-based capacitor module 12 drives it. Since the output of the charger module 11 is directly controlled by three-phase alternating current and is not controlled by the carbon-based capacitor control module, even if the first driving battery 1E1 is out of power or the first carbon-based capacitor 121 cannot work normally, the charger module 11 can still output normally. That is, if a circuit failure occurs in the first carbon-based capacitor control module 17, the charger module 11 can also output the power supply voltage normally to the subsequent equipment. The charger module 11 and the carbon-based capacitor module are controlled by different control modules respectively, and the entire circuit cannot be output due to the failure of the carbon-based capacitor control module or the carbon-based capacitor module. The working efficiency of the tire crane power drive system 10 is effectively improved.

[0059] The utility model provides a tire crane power drive system, which includes a charger module, a first carbon-based capacitor module, a switch module, and an output module. The charger module can output a power supply voltage to a subsequent device. Thus, the subsequent device can be started and work normally based on the power supply voltage. Because the tire crane power drive system first supplies a small current through the charger module and then supplies a large current through the charger module, the tire crane power drive system can start the subsequent device smoothly. And the first carbon-based capacitor module can adjust the power supply voltage through the switch module, so that the power supply voltage output to the subsequent device is more stable, and then the subsequent device can maintain a stable working state for a long time. The technical problem that the existing tire crane is difficult to maintain a stable working state for a long time is effectively solved. Moreover, the output module is provided with a frequency conversion unit, and the frequency conversion unit is provided with a frequency converter. The frequency converter can be used to adjust the voltage value, frequency, phase and other parameters of the power supply voltage, so as to achieve precise control of the tire crane. The setting of the frequency conversion unit can improve the production efficiency of the tire crane equipment, reduce the energy consumption of the tire crane equipment, and extend the life of the tire crane equipment.
