Description

Technical Field

[0001] The utility model relates to the technical field of transport vehicle unloading, in particular to a control system and a thermal insulation material spiral transport vehicle. Background Art

[0002] The insulation material spiral transport vehicle is a new type of special vehicle used in the electrolytic aluminum industry to transport insulation materials. The vehicle's loading, transportation, and unloading processes are sealed and leak-free, making it one of the most important means of transportation for transporting insulation materials.

[0003] Therefore, the Chinese invention patent with the publication date of March 12, 2024 and the publication number CN117681763A proposes an insulation material transport vehicle device and a method of use for the electrolytic aluminum process, which includes a tank shell, a horizontal conveyor, and a vertical conveyor. The horizontal conveyor is fixedly connected to the bottom of the tank shell, and the interior of the tank shell is connected to the horizontal conveyor. The vertical conveyor is arranged at the end of the horizontal conveyor, and the vertical conveyor is connected to the horizontal conveyor. Screw rods are arranged in the vertical conveyor and the horizontal conveyor.

[0004] When in use, the vertical conveyor and the horizontal conveyor work, and the internal screw rotates to transport the insulation material in the tank shell into the vertical conveyor, and unloads it at the end of the vertical conveyor. The vertical conveyor can rotate along the horizontal conveyor to unload, so that the transported insulation material is in a pressure-free state.

[0005] In response to the above technology, the current insulation material transport vehicles unload materials through fuel-driven horizontal conveyors and vertical conveyors. The vehicle fuel costs are high, and the fuel value and exhaust pollution as well as the efficiency of intermediate transfer energy are reduced, polluting the air, which is inconsistent with environmental trends and responses to green development. Utility Model Content

[0006] In order to improve the energy efficiency of unloading and protect the motor, the utility model provides a unloading control system and a thermal insulation material spiral transport vehicle.

[0007] The utility model provides a discharge control system and a thermal insulation material spiral transport vehicle, which adopts the following technical solutions:

[0008] In the first aspect, a unloading control system includes an electrical module of a distribution box, a hydraulic control module and a one-button sequential start and stop module; the electrical module of the distribution box includes an air switch, a first frequency converter, a second frequency converter, a motor starting main contact and a power unit motor, the input end of the first frequency converter is connected to three-phase electricity, and an air switch is provided on the three-phase electricity, the output end of the first frequency converter is connected to the main screw motor, the input end of the second frequency converter is connected to three-phase electricity, and the output end of the second frequency converter is connected to the auxiliary screw motor, the motor starting main contact is provided on the three-phase electricity connected between the first frequency converter and the second frequency converter, the power unit motor is connected to three-phase electricity, and the motor starting main contact is provided between the power unit motor and the three-phase electricity.

[0009] By adopting the above technical solution, three-phase electricity is used for power supply, and the first and second frequency converters provide the required power supply voltage according to the actual needs of the motor. The main screw motor is protected and soft-started by the first frequency converter, and the auxiliary screw motor is protected and soft-started by the second frequency converter; the power unit motor is protected by a leakage protector, the energy transmission efficiency of electricity is high, and no fuel is used, which will not cause pollution to the environment.

[0010] Furthermore, the electrical module of the distribution box also includes a phase-off and phase-sequence relay, which is electrically connected to the three phases.

[0011] By adopting the above technical solution, after the electrical module of the distribution box is connected to the three-phase power, the phase failure and phase sequence relay can be used to detect whether the phase sequence of the mains power in the unloading workshop is correct, eliminating the phenomenon of the power unit motor pump being reversed due to the wrong sequence of three-phase power, thereby fundamentally reducing the probability of damage to the motor pump.

[0012] Furthermore, the hydraulic control module includes a power supply, a forward solenoid valve, a reverse solenoid valve, a first relay, a second relay, a phase failure and phase sequence relay contact, a first relay contact, a second relay contact, a motor starter and a wireless remote control receiver; the positive pole of the power supply is connected to the wireless remote control receiver, the wireless remote control receiver is connected to the negative pole of the power supply, one end of the forward solenoid valve is connected to the wireless remote control receiver, and the other end is connected to the negative pole of the power supply, and the first relay is connected in parallel with the forward solenoid valve; one end of the reverse solenoid valve is connected to the wireless remote control receiver, and the other end is connected to the negative pole of the power supply, the second relay is connected in parallel with the reverse solenoid valve, the first relay contact and the second relay contact are connected in parallel and then connected to the positive and negative poles, the phase failure and phase sequence relay contact and the motor starter are connected in series in the circuit in which the first relay contact and the second relay contact are connected in parallel.

[0013] By adopting the above technical solution, when the vehicle is unloading, the forward solenoid valve, reverse solenoid valve and power unit motor pump are controlled by the wireless remote control receiver to drive the hydraulic slewing bearing to rotate. Only when the phase sequence of the mains power in the unloading workshop is correct, the normally open contact will be closed, and the motor starter can be energized, which completely ensures that the power unit motor will not be damaged due to reversal.

[0014] Furthermore, the one-button sequential start and stop module includes a panel dual switch and a dual-circuit relay. The panel dual switch includes a first switch and a second switch. The dual-circuit relay has a first group of connection terminals, a second group of connection terminals, and a third group of connection terminals. The first group of connection terminals has a switch inside to connect the two terminals, the second group of connection terminals has a switch inside to connect the two terminals, and the third group of connection terminals has a switch inside to connect the two terminals. The wireless remote control receiver is connected to the ground wire through the first group of connection terminals. The first inverter is provided with a DI1 port, a DI3 port, and a COM port. The DI1 port of the first inverter is connected to the COM port of the first inverter through the second group of connection terminals. The second inverter is provided with an SI port, an S2 port, and a COM port. The S1 port of the second inverter is connected to the COM port of the second inverter through the third group of connection terminals. The COM port of the first inverter is connected to the DI3 port of the first inverter through the first switch; and the COM port of the second inverter is connected to the S2 port of the second inverter through the second switch.

[0015] By adopting the above technical solution, the main screw motor and the auxiliary screw motor are soft-started by two inverters respectively during unloading, and the inverter is started and shut down in one button sequence by adopting the terminal start method. The operation is simple and the operator no longer needs to press the operation panel buttons of the two inverters in sequence to start and shut down, which saves the operator's time.

[0016] Furthermore, when the first and second inverters are switched to terminal start, the function table P4.35 of the first inverter is set to the first value, and the DI1 terminal is delayed to open for the time corresponding to the first value; the function table E05.15 of the second inverter is set to the second value, and the S1 terminal is delayed to close for the time corresponding to the second value.

[0017] By adopting the above technical solution, when the main spiral motor and the auxiliary spiral motor are started by remote control, the DI1 terminal is delayed to open, the auxiliary spiral motor starts immediately, and the main spiral motor is delayed to start. When the main spiral motor and the auxiliary spiral motor are shut down by remote control, the S1 terminal is delayed to close. At this time, the main spiral motor is immediately shut down and the auxiliary spiral motor is delayed to close. The unloading is cleaner and the insulation material will not remain in the auxiliary spiral conveying mechanism, thereby realizing the automation of the start and shutdown of the main spiral motor and the auxiliary spiral motor.

[0018] Furthermore, the one-button sequential start and stop module also includes a wireless remote control, which can wirelessly output electrical signals. After receiving the signal, the wireless receiver outputs the electrical signal, and realizes the connection between the terminal S1 and COM or the connection between the terminal DI1 and COM through the dual-way relay.

[0019] By adopting the above technical solution, the operator can directly remotely control the motor to start or stop through the remote control. When the operator uses the wireless remote control, the COM of the first inverter is connected to DI3, and the first inverter internally shields the state in which DI1 and COM are connected through a two-way relay. The COM of the second inverter is connected to S2, and the first inverter internally shields the state in which S1 and COM are connected through a two-way relay. There is no need to press the operation panel buttons of the two inverters in sequence to start and stop, which is simple to operate and will not cause the situation in which the two inverters are operated in the wrong sequence, thereby improving the safety of operation.

[0020] In the second aspect, a thermal insulation material spiral transport vehicle comprises a vehicle body, a tank body, a main spiral conveying mechanism, an auxiliary spiral conveying mechanism and a hydraulic slewing support, wherein the main spiral conveying mechanism is fixedly connected to the vehicle body, the tank body is arranged on the upper part of the main spiral conveying mechanism, the tank body is communicated with the interior of the main spiral conveying mechanism, the auxiliary spiral conveying mechanism is arranged at the first end of the main spiral conveying mechanism, the hydraulic slewing support is arranged at the first end of the main spiral conveying mechanism, the first end of the main spiral conveying mechanism extends into the hydraulic slewing support, the auxiliary spiral conveying mechanism is fixedly connected to the hydraulic slewing support, the auxiliary spiral conveying mechanism is arranged vertically to the main spiral conveying mechanism, and the main spiral conveying mechanism is communicated with the interior of the auxiliary spiral conveying mechanism.

[0021] By adopting the above technical solution, when unloading, the main spiral conveying mechanism and the auxiliary spiral conveying mechanism are opened, and the hydraulic slewing bearing drives the auxiliary spiral conveying mechanism to rotate 90 degrees from the longitudinal direction to the transverse direction. The insulation material is conveyed to the auxiliary spiral conveying mechanism through the main spiral conveying mechanism, and finally unloaded in the auxiliary spiral conveying mechanism. The vehicle can unload by parking beside the material port along the lane direction, and no longer needs to park horizontally in the aisle, which facilitates the unloading work of the vehicle in a limited space and improves the safety of night transportation vehicles.

[0022] Furthermore, the main screw conveying mechanism includes a main screw motor, a first reducer and a main conveying screw, and the main screw motor is connected to the main conveying screw through the first reducer; the auxiliary screw conveying mechanism includes an auxiliary screw motor, a second reducer, and an auxiliary conveying screw, and the auxiliary screw motor is connected to the auxiliary conveying screw through the second reducer.

[0023] By adopting the above technical solution, the main screw motor rotates through the first reducer to drive the main conveying screw to work. The main conveying screw conveys the insulation material to the auxiliary conveying screw. The insulation material in the tank body will continuously enter the main conveying screw. The auxiliary screw motor drives the second reducer to rotate, and conveys the insulation material in the auxiliary conveying screw to the designated position to complete unloading. The above unloading method can ensure that the conveyed insulation material is in a pressure-free state, thereby reducing dust pollution.

[0024] Furthermore, a speed difference is set between the main screw motor and the auxiliary screw motor, and the speed of the main screw motor is slower than that of the auxiliary screw motor.

[0025] By adopting the above technical solution, the rotation speed of the auxiliary screw motor is fast, which reduces the risk of blockage caused by excessive insulation material entering the auxiliary screw conveying mechanism and untimely conveying.

[0026] In summary, the present invention has at least one of the following beneficial technical effects:

[0027] 1. Through the configuration of the electrical module in the distribution box, three-phase power is provided. The first and second inverters provide the required power voltage according to the actual needs of the motor. The main screw motor is protected and soft-started by the first inverter, and the auxiliary screw motor is protected and soft-started by the second inverter. The power unit motor is protected by a leakage protector. The power transmission is highly efficient and does not use fuel, which will not cause environmental pollution.

[0028] 2. By setting the phase-failure and phase-sequence relays, after the electrical module of the distribution box is connected to the three-phase power, the phase-failure and phase-sequence relays can detect whether the phase sequence of the mains power in the unloading workshop is correct, eliminating the phenomenon of the power unit motor pump being reversed due to the wrong sequence of three-phase power, thereby fundamentally reducing the probability of damage to the motor pump.

[0029] 3. Through the setting of the one-button sequential start and stop module, when the remote control is used to start the main spiral motor and the auxiliary spiral motor, the auxiliary spiral motor starts immediately and the main spiral motor starts with a delay. When the remote control is used to shut down the main spiral motor and the auxiliary spiral motor, the main spiral motor shuts down immediately and the auxiliary spiral motor shuts down with a delay. This makes unloading cleaner and prevents insulation material from remaining in the auxiliary spiral conveying mechanism. When the operator controls the motor to start or stop, he can directly control it remotely through the remote control, without having to press the operation panel buttons of the two inverters in sequence to start and stop, which makes operation simple.

[0038] A connecting pipe is provided on the side of the auxiliary spiral conveying mechanism 400, which is connected to the interior of the auxiliary spiral conveying mechanism 400 and is perpendicular to the auxiliary spiral conveying mechanism 400; the connecting pipe on the auxiliary spiral conveying mechanism 400 is fixedly connected to the hydraulic slewing bearing 440. At this time, the connecting pipe is coaxial with the main spiral conveying mechanism 300, the auxiliary spiral conveying mechanism 400 is arranged perpendicular to the main spiral conveying mechanism 300, and the main spiral conveying mechanism 300 is connected to the interior of the auxiliary spiral conveying mechanism 400; the main spiral motor 310 and the auxiliary spiral motor 410 are set with a speed difference, and the speed of the main spiral motor 310 is slower than the speed of the auxiliary spiral motor 410.

[0039] Reference Figure 1 The main spiral conveying mechanism 300 includes a main spiral motor 310, a first reducer 320, and a main conveying screw 330.

The main spiral motor 310 is connected to the auxiliary conveying screw 430 through the second reducer 420.

[0040] In this way, when arriving at the designated position for unloading, the hydraulic slewing bearing 440 rotates to drive the auxiliary screw conveying mechanism 400 to rotate 90 degrees from a vertical state to a horizontal state, the main screw conveying mechanism 300 and the auxiliary screw conveying mechanism 400 are opened, and the thermal insulation material is conveyed to the auxiliary screw conveying mechanism 400 through the main screw conveying mechanism 300, and finally unloaded in the auxiliary screw conveying mechanism 400. The vehicle can unload by parking beside the material port along the lane direction, and no longer needs to park horizontally in the aisle, which facilitates the unloading work of the vehicle in a limited space and improves the safety of night-time transportation vehicles. The above-mentioned unloading method can ensure that the conveyed thermal insulation material is in a pressure-free state, thereby reducing dust pollution.

[0041] The secondary screw motor 410 has a high rotation speed, which reduces the risk of blockage caused by excessive heat-insulating material entering the secondary screw conveying mechanism 400 and untimely conveying.

[0042] Reference Figure 2The electrical module of the distribution box includes an air switch 510, a first frequency converter 520, a second frequency converter 530, a phase-off and phase sequence relay 550, a motor starting main contact 570 and a power unit motor 540. The input end of the first frequency converter 520 is connected to three-phase electricity, and an air switch 510 is provided on the three-phase electricity. The output end of the first frequency converter 520 is connected to the main spiral motor 310, the input end of the second frequency converter 530 is connected to three-phase electricity, and the output end of the second frequency converter 530 is connected to the auxiliary spiral motor 410.

The motor starting main contact 570 is provided between the power unit motor 540 and the three-phase electricity, and the phase-off and phase sequence relay 550 is connected to the three-phase electricity.

[0043] In this way, the driving mode during unloading is changed from fuel to three-phase electricity. The first frequency converter 520 and the second frequency converter 530 provide the required power supply 610 voltage according to the actual needs of the motor. The main spiral motor 310 is protected and soft-started by the first frequency converter 520, and the auxiliary spiral motor 410 is protected and soft-started by the second frequency converter 530; the power unit motor 540 is protected by the leakage protector 560, the energy transmission efficiency of electricity is high, and no fuel is used, which will not cause pollution to the environment; the phase failure and phase sequence relay 550 can be used to detect whether the phase sequence of the mains power in the unloading workshop is correct, eliminating the phenomenon of the power unit motor 540 pump reversing due to the wrong sequence of three-phase electricity, thereby fundamentally reducing the probability of damage to the motor pump.

[0044] Reference Figure 3 The hydraulic control module includes a power supply 610, a forward solenoid valve 620, a reverse solenoid valve 630, a first relay 640, a second relay 650, a phase failure and phase sequence relay 550 contact, a first relay contact 680, a second relay contact 690, a motor starter 660 and a wireless remote control receiver 670; the positive pole of the power supply 610 is connected to the wireless remote control receiver 670, and the wireless remote control receiver 670 is connected to the negative pole of the power supply 610. One end of the forward solenoid valve 620 is connected to the wireless remote control receiver 670 and the other end is connected to the negative pole of the power supply 610. The first relay 640 is connected in parallel with the forward solenoid valve 620; one end of the reverse solenoid valve 630 is connected to the wireless remote control receiver 670 and the other end is connected to the negative pole of the power supply 610. The second relay 650 is connected in parallel with the reverse solenoid valve 630. The first relay contact 680 and the second relay contact 690 are connected in parallel and then connected to the positive and negative poles. The contacts of the phase failure and phase sequence relay 550 and the motor starter 660 are connected in series in a circuit in which the first relay contact 680 and the second relay contact 690 are connected in parallel.

[0045] In this way, when the vehicle is unloading, the forward solenoid valve 620, the reverse solenoid valve 630 and the power unit motor 540 pump are controlled by the wireless remote control receiver 670 to drive the hydraulic slewing bearing 440 to rotate. Only when the phase sequence of the mains electricity in the unloading workshop is correct, the normally open contact will be closed, and the motor starter 660 can be energized, which completely ensures that the power unit motor 540 will not be damaged due to reversal. The hydraulic slewing bearing 440 drives the secondary screw conveying mechanism 400 to rotate to the specified position for unloading.

[0046] Reference Figure 4 The one-button sequential start and stop module includes a panel dual switch 710 and a dual-circuit relay 720. The panel dual switch 710 includes a first switch and a second switch. The dual-circuit relay 720 has a first group of connection terminals, a second group of connection terminals, and a third group of connection terminals. The first group of connection terminals has a switch inside to connect the two terminals, the second group of connection terminals has a switch inside to connect the two terminals, and the third group of connection terminals has a switch inside to connect the two terminals. The wireless remote control receiver 670 is connected to the ground wire through a first group of connection terminals. The first inverter 520 is provided with a DI1 port, a DI3 port, and a COM port. The DI1 port of the first inverter 520 is connected to the COM port of the first inverter 520 through a second group of connection terminals. The second inverter 530 is provided with an S1 port, an S2 port, and a COM port. The S1 port of the second inverter 530 is connected to the COM port of the second inverter 530 through a third group of connection terminals. The COM port of the first inverter 520 is connected to the DI3 port of the first inverter 520 through a first switch. The COM port of the second inverter 530 is connected to the S2 port of the second inverter 530 through a second switch.

After receiving the signal, the wireless receiver outputs the electrical signal. The connection between terminals S1 and COM or the communication between terminals DI1 and COM is achieved through the dual-way relay 720.

[0047] When the first inverter 520 and the second inverter 530 are switched to terminal start, the function table P4.35 of the first inverter 520 is set to the first value, and the DI1 terminal is delayed to open for the time corresponding to the first value; the function table E05.15 of the second inverter 530 is set to the second value, and the S1 terminal is delayed to close for the time corresponding to the second value.

[0048] In this way, when the main spiral motor 310 and the auxiliary spiral motor 410 are started by remote control, the DI1 terminal is delayed to open, the auxiliary spiral motor 410 is started immediately, and the main spiral motor 310 is delayed to start. When the main spiral motor 310 and the auxiliary spiral motor 410 are shut down by remote control, the S1 terminal is delayed to close. At this time, the main spiral motor 310 is immediately shut down, and the auxiliary spiral motor 410 is delayed to close. The unloading is cleaner and the insulation material will not remain in the auxiliary spiral conveying mechanism 400, thereby realizing the automation of the start and shutdown of the main spiral motor 310 and the auxiliary spiral motor 410.

[0049] When the operator controls the opening or closing of the unloading, he directly controls it remotely through the remote controller. When the operator uses the wireless remote controller for control, the COM of the first inverter 520 is connected to DI3, and the first inverter 520 internally shields the state in which DI1 and COM are connected through the dual-path relay 720. The COM of the second inverter 530 is connected to S2, and the first inverter 520 internally shields the state in which S1 and COM are connected through the dual-path relay 720. There is no need to press the operation panel buttons of the two inverters in sequence to start and shut down. The operation is simple, and there will be no situation in which the two inverters are operated incorrectly in sequence, thereby improving the safety of the operation.

[0050] The implementation principle of the embodiment of this application is:

[0051] During unloading, the hydraulic control module controls the rotation of the hydraulic slewing bearing 440, and the hydraulic slewing bearing 440 drives the auxiliary screw conveying mechanism 400 to rotate 90 degrees from the longitudinal direction to the transverse direction. The one-button sequential start and stop module can remotely control the main screw conveying mechanism 300 and the auxiliary screw conveying mechanism 400 to convey materials outward from the tank body 200, and finally transport the insulation material in the main screw conveying mechanism 300 and the auxiliary screw conveying mechanism 400 to the designated position to complete unloading. Electric drive is used instead of fuel drive. The energy transmission efficiency of electricity is high, which reduces the pollution to the environment. The vehicle can unload by parking beside the material port along the lane direction, and no longer needs to be parked horizontally in the aisle. This facilitates the unloading work of the vehicle in a limited space and improves the safety of night transportation vehicles. The above unloading method can ensure that the conveyed insulation material is in a pressure-free state, reducing dust pollution.

[0052] The driving mode during unloading is changed from fuel to three-phase electricity. The first frequency converter 520 and the second frequency converter 530 provide the required power supply 610 voltage according to the actual needs of the motor. The main screw motor 310 is protected and soft-started by the first frequency converter 520, and the auxiliary screw motor 410 is protected and soft-started by the second frequency converter 530; the power unit motor 540 is protected by the leakage protector 560, the energy transmission efficiency of electricity is high, and no fuel is used, which will not cause pollution to the environment; the phase failure and phase sequence relay 550 can be used to detect whether the phase sequence of the mains power in the unloading workshop is correct, eliminating the phenomenon of the power unit motor 540 pump reversing due to the wrong sequence of three-phase electricity, thereby fundamentally reducing the probability of damage to the motor pump.

[0053] When the vehicle is unloading, the forward solenoid valve 620, the reverse solenoid valve 630 and the power unit motor 540 pump are controlled by the wireless remote control receiver 670 to drive the hydraulic slewing bearing 440 to rotate. Only when the phase sequence of the mains electricity in the unloading workshop is correct, the normally open contact will be closed, and the motor starter 660 can be energized, which completely ensures that the power unit motor 540 will not be damaged due to reversal. The hydraulic slewing bearing 440 drives the secondary screw conveying mechanism 400 to rotate to the specified position for unloading.

[0054] When the main spiral motor 310 and the auxiliary spiral motor 410 are started by remote control, the DI1 terminal is opened with a delay, the auxiliary spiral motor 410 is started immediately, and the main spiral motor 310 is started with a delay. When the main spiral motor 310 and the auxiliary spiral motor 410 are shut down by remote control, the S1 terminal is closed with a delay. At this time, the main spiral motor 310 is shut down immediately and the auxiliary spiral motor 410 is shut down with a delay. The unloading is cleaner and the insulation material will not remain in the auxiliary spiral conveying mechanism 400, thereby realizing the automation of the start and shutdown of the main spiral motor 310 and the auxiliary spiral motor 410.

[0055] When the operator controls the opening or closing of the unloading, he directly controls it remotely through the remote controller. When the operator uses the wireless remote controller for control, the COM of the first inverter 520 is connected to DI3, and the first inverter 520 internally shields the state in which DI1 and COM are connected through the dual-path relay 720. The COM of the second inverter 530 is connected to S2, and the first inverter 520 internally shields the state in which S1 and COM are connected through the dual-path relay 720. There is no need to press the operation panel buttons of the two inverters in sequence to start and shut down. The operation is simple, and there will be no situation in which the two inverters are operated incorrectly in sequence, thereby improving the safety of the operation.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
