[0047] Traditional container spreaders have a high failure rate and usually need to rely on on-site maintenance by maintenance personnel, which requires maintenance personnel to have a high level of maintenance skills and be able to respond quickly in emergency situations.

[0048] The utility model provides a container spreader control console 100.

[0049] See also Figure 1 In one embodiment of the utility model, the container spreader control console 100 is applied to a spreader control system, which includes a plurality of spreader motors 300 and a spreader electric control box 200, wherein the spreader electric control box 200 is electrically connected to the plurality of spreader motors 300; the spreader electric control box 200 is used to drive the plurality of spreader motors 300.

[0050] It should be noted that the multiple spreader motors 300 may include a spreader oil pump motor 310, a spreader telescopic motor 320, a spreader opening and closing motor 330, and a spreader guide plate up and down motor 340. Among them, the spreader oil pump motor 310 can drive the hydraulic oil pump to provide hydraulic pressure to realize the lifting and lowering action of the spreader. The spreader telescopic motor 320 can drive the spreader to extend and retract to adapt to containers of different sizes and shapes. The spreader opening and closing motor 330 can drive the spreader to open or close to clamp the container to ensure that the container can be safely and stably lifted. The spreader guide is a device for guiding the container. The spreader guide plate up and down motor 340 can drive the position of the spreader guide to rise or fall, so as to correctly guide the position of the container and ensure accurate lifting operation.

[0051] The container spreader control console 100 comprises:

[0052] The remote control sending circuit 110 is used to output a first trigger signal when triggered by a user.

[0053] It should be noted that the remote control transmission circuit 110 may include switches / buttons related to the actions of multiple spreader motors 300. For example, the remote control transmission circuit 110 may include an oil pump working switch, a spreader extension button, a spreader retraction button, a spreader unlocking button, a spreader locking button, a spreader guide plate rising button, and a spreader guide plate lowering button, which can respectively control the spreader oil pump motor 310 to drive the operation of the hydraulic oil pump, control the spreader extension motor 320 to drive the spreader to extend and retract, control the spreader opening and closing motor 330 to drive the spreader to unlock and lock, and control the spreader guide plate upper and lower motor 340 to drive the spreader guide plate to rise and fall. In this way, maintenance personnel can output different trigger signals by operating the above switches or buttons, corresponding to triggering and controlling different operations of multiple spreader motors 300.

[0054] The remote control receiving circuit 120 is communicatively connected with the remote control transmitting circuit 110 .

[0055] It should be noted that the remote control receiving circuit 120 and the remote control sending circuit 110 can communicate via wireless radio frequency technology (such as Bluetooth, Wi-Fi, Zigbee, etc.). In this way, the present embodiment can realize remote control operation, that is, the maintenance personnel can operate remotely, by operating different switches or buttons, standing at a distance to observe the actions of different spreaders, to determine whether the spreader motor is working abnormally, so as to detect the abnormality in advance and perform maintenance.

[0056] A programming controller PLC130, wherein a first input terminal of the programming controller PLC130 is electrically connected to the remote control receiving circuit 120;

[0057] The programming controller PLC130 is used to output a first control signal according to a first trigger signal.

[0058] It should be noted that the programmable logic controller PLC130 (Programmable Logic Controller) has built-in logic algorithms and logic programs, and can output different logic control signals according to different input trigger signals to control different operations of multiple hoist motors 300.

[0059] The operation console control circuit 140 is electrically connected to the signal output end of the programmable controller PLC130 and the controlled end of the spreader electric control box 200;

[0060] The operating console control circuit 140 is used to trigger the spreader electric control box 200 to drive the plurality of spreader motors 300 according to the first control signal.

[0061] It should be noted that the console control circuit 140 can receive the first control signal, perform signal processing such as signal amplification and logic judgment, and convert it into an operation signal that can be recognized by the spreader electric control box 200 to trigger the spreader electric control box 200 to drive multiple spreader motors 300 to perform different operations. For example, the relevant contactor of the spreader electric control box 200 can be triggered to open, so that the spreader electric control box 200 can output the corresponding drive current to drive the spreader telescopic motor 320 to extend.

[0062] It should be noted that, for a type of container spreader with a higher failure rate, a spare set of this type of container spreader can be prepared, and the main spreader and the spare spreader can be replaced and used alternately according to the working hours and workload. At the same time, the replaced spreader can be inspected and repaired in advance through the container spreader control console 100 of this embodiment to reduce the failure rate of the container spreader operation.

[0063] It should be noted that this embodiment can achieve circuit separation between the main power circuit and the control circuit, specifically, the circuit separation between the multiple spreader motors 300 and the spreader electric control box 200 and the container spreader control console 100 can be achieved, which can avoid the influence of electromagnetic interference or power fluctuation between different circuits on the maintenance operation. At the same time, it can reduce the risk of accidental electric shock or equipment damage during the maintenance of the container spreader, thereby improving safety.

[0064] In this embodiment, when the switch / button on the remote control sending circuit 110 is triggered by the maintenance personnel, a first trigger signal is output. The remote control receiving circuit 120 receives the first trigger signal and outputs it to the programming controller PLC130. The programming controller PLC130 converts the first trigger signal into a first control signal output that can be recognized by the operation console control circuit 140 through the internal logic program. The operation console control circuit 140 triggers the spreader electric control box 200 to drive the action of multiple spreader motors 300 according to the first control signal. The maintenance personnel can determine whether the corresponding spreader motor has failed by observing whether the actions of the multiple spreader motors 300 are abnormal, and perform early maintenance in time. For example, when the maintenance personnel triggers the spreader extension button to open, it can be observed whether the spreader performs the extension action, and then determine whether the spreader extension motor 320 is working normally, and whether it needs to be repaired. Among them, in this embodiment, multiple main spreader motors and multiple spare spreader motors that are used alternately can be repaired in advance to reduce their failure rate during operation. In this way, the present embodiment can detect and repair potential problems before the spreader motor fails through preventive maintenance, thereby reducing the frequency of unexpected downtime and emergency maintenance. Moreover, by performing maintenance through the container spreader control console 100 of the present embodiment, equipment operation and maintenance can be more standardized and regularized, reducing the reliance on the on-site maintenance capabilities of maintenance personnel, thereby improving the reliability and continuous operation efficiency of the equipment.

[0065] In the present utility model, when the switch / button on the remote control sending circuit 110 is triggered by the maintenance personnel, a first trigger signal is output. The remote control receiving circuit 120 receives the first trigger signal and outputs it to the programming controller PLC130. The programming controller PLC130 converts the first trigger signal into a first control signal output that can be recognized by the operating console control circuit 140 through the internal logic program. The operating console control circuit 140 triggers the spreader electric control box 200 to drive the action of multiple spreader motors 300 according to the first control signal. The maintenance personnel can then determine whether the corresponding spreader motor has failed by observing whether the actions of the multiple spreader motors 300 are abnormal, and perform maintenance in time. In this way, the present utility model can detect and repair potential problems before the spreader motor fails through preventive maintenance, thereby reducing the frequency of unexpected shutdowns and emergency repairs, and reducing the failure rate of the spreader motor during operation.

[0066] See also Figure 2 In one embodiment of the utility model, the second input terminal of the programming controller PLC130 is electrically connected to the signal feedback terminal of the spreader electric control box 200;

[0067] The spreader electric control box 200 is used to output a spreader limit feedback signal according to the working status of multiple spreader motors 300;

[0068] The programming controller PLC130 is used to output a first control signal according to the first trigger signal and the spreader limit feedback signal.

[0069] It should be noted that the spreader motor can be used to drive the spreader to perform different actions. When the spreader reaches a limited position, the spreader electric control box 200 can detect that the working state of the spreader motor has reached a limited state, and the driving current has changed, and then the spreader limit feedback signal is output to the programming controller PLC130. At this time, the programming controller PLC130 no longer outputs a control signal to control the continued action. For example, the spreader guide plate upper and lower motor 340 can drive the spreader guide plate to guide the position of the container, wherein the spreader guide plate upper and lower motor 340 has a maximum position and a minimum position that can drive the spreader guide plate to rise. Here, the maximum position and the minimum position of the spreader guide plate are the limited positions of the spreader. At this time, the spreader guide plate upper and lower motor 340 also rotates to the maximum rotation position and the minimum rotation position at the same time. The spreader electric control box 200 can monitor its state changes by means of sensors or encoders. When the spreader guide plate upper and lower motor 340 rotates to the maximum rotation position or the minimum rotation position, the spreader electric control box 200 outputs a spreader limit feedback signal to notify the programming controller PLC130 to stop controlling the spreader guide plate upper and lower motor 340 to continue rotating.

[0070] In this embodiment, the spreader electric control box 200 can output a spreader limit feedback signal according to the working status of the plurality of spreader motors 300, the programming controller PLC130 can output a first control signal according to the first trigger signal and the spreader limit feedback signal, and the console control circuit 140 can trigger the spreader electric control box 200 to drive the plurality of spreader motors 300 according to the first control signal. In this way, the maintenance personnel can determine whether the corresponding spreader motor is in a normal working state by observing whether the spreader can perform the corresponding operation at the limited position, and can determine whether the corresponding spreader motor has a fault, and perform maintenance in time to prevent it from being unable to perform the corresponding operation at the limited position during the operation, thereby reducing the failure rate of the operation.

[0072] A manual control circuit 150, the manual control circuit 150 is electrically connected to the third input terminal of the programmable controller PLC130;

[0073] The manual control circuit 150 is used to output a second trigger signal when triggered by a user;

[0074] The programming controller PLC130 is used to output a second control signal according to the second trigger signal and the spreader limit feedback signal;

[0075] The operating console control circuit 140 is used to trigger the spreader electric control box 200 to drive the plurality of spreader motors 300 according to the second control signal.

[0076] In this embodiment, the manual control circuit 150 may include an oil pump working switch, a spreader extension button, a spreader retraction button, a spreader unlock button, a spreader lock button, a spreader guide plate raising button, and a spreader guide plate lowering button.

[0077] In this embodiment, when the switch / button on the manual control circuit 150 is triggered by the maintenance personnel, a second trigger signal is output. At the same time, the spreader electric control box 200 can output a spreader limit feedback signal according to the working status of the multiple spreader motors 300. Then the programming controller PLC130 can output a second control signal through the internal logic program by combining the second trigger signal and the spreader limit feedback signal. The console control circuit 140 triggers the spreader electric control box 200 to drive the multiple spreader motors 300 according to the second control signal. Then the maintenance personnel can determine whether the corresponding spreader motor has failed by observing whether the actions of the multiple spreader motors 300 are abnormal, and perform early maintenance in time. In this way, in this embodiment, the action of the corresponding spreader motor can be triggered by the manual control circuit 150 or the remote control sending circuit 110 and the remote control receiving circuit 120, and the multiple main spreader motors and multiple spare spreader motors used alternately are repaired in advance to reduce their failure rate during the operation process. This embodiment improves the selectivity of triggering the switch / button for maintenance.

The overcurrent and short-circuit protection circuit 164 is used to cut off the power supply when it is detected that the input current of the operating console control circuit 140 is higher than the preset current threshold.

[0086] It should be noted that when an external power supply is connected, it is necessary to determine whether the phase sequence of the external power supply is correct through the phase sequence protection circuit 161. Only when it is determined that the external power supply is not lacking a phase through the phase loss protection circuit 162, the external power supply is connected and the operating console control circuit 140 is started to trigger the hoisting device electrical control box 200 to drive multiple hoisting device motors 300.
