[0029] The utility model is now described in further detail with reference to the accompanying drawings.

[0030] A maintenance system for a sintering trolley wheel comprises: a carriage 1, a two-dimensional code label 2, a wheel 3, a track 4, a proximity switch 5, a wheel condition detection device 6, a two-dimensional code recognition camera 7, a lubricant adding robot 8 and a controller 9, wherein the wheel condition detection device 6, the two-dimensional code recognition camera 7, the proximity switch 5 and the lubricant adding robot 8 are all electrically connected to the controller 9; wherein,

[0031] The proximity switch 5 is installed on the track 4. When the wheel 3 contacts the proximity switch 5, the contact signal of the wheel 3 is sent to the controller 9. The controller 9 sends a collection start signal to the QR code recognition camera 7. The QR code recognition camera 7 is used to recognize the QR code sign 2 and the number of the carriage 1.

[0032] The QR code label 2 has the number of the carriage 1 and is set on the side of the carriage 1. There is no fixed requirement for the position, and it must be within the collection range of the QR code recognition camera 7; the sintering trolley is composed of several carriages 1; the carriage 1 is composed of two sets of wheels 3.

[0033] The controller 9 can store information such as maintenance and oiling of the two sets of wheels 3; the maintenance and oiling information of the wheels 3 can also be obtained through the host computer 10; the maintenance and oiling information includes the number of running cycles of the wheels 3, the last maintenance time, the last oiling time, the number of running cycles of the wheels after oiling, etc.; the maintenance information is usually manually maintained and entered by the maintenance personnel after the maintenance is completed, and the oiling information is automatically obtained by the controller 9 after the lubricant adding robot 8 completes the oiling.

[0034] The faults of the wheel 3 to be inspected include: wheel deformation and damage, bearing damage, shaft surface wear and locking nut falling off; among them, the shaft surface wear is divided according to the severity. If the severity is relatively light, it is only necessary to add lubricant through the lubricant adding robot 8 for maintenance. If the severity is relatively severe, it is necessary to notify the maintenance personnel; other faults require notification of the maintenance personnel for manual inspection.

[0035] The controller 9 sets the maintenance period of wheel failure and the threshold of the number of cycles; for example, the probability of wheel deformation failure is relatively small, so the period can be set to 3 months; the probability of bearing damage and shaft wear is relatively high, so the period is 1 month; the probability of locking nut falling off is the highest, so the period is 2 weeks; the above maintenance period periods can be customized according to actual working conditions.

[0036] The two-dimensional code recognition camera 7 is fixed beside the track, fixed by a support rod, or by other fixing devices, such as ceiling installation, as long as it can accurately collect the information of the two-dimensional code sign 2; the two-dimensional code recognition camera 7 is set at the rear end of the sintering trolley in the driving direction, and the wheel condition detection device 6 can be set on the left or right side of the proximity switch 5.

[0037] The controller 9 compares the collected current time of the wheel 3 with the maintenance time and maintenance status of the corresponding wheel 3 in the controller 9 to determine whether the wheel 3 needs maintenance; for example, the time is April 18, 2024, and the wheel deformation failure maintenance time is January 1, 2024, which exceeds the deadline of 3 months, so it is necessary to send maintenance inspection information to the host computer 10 through the controller 9 to remind the maintenance personnel to check the wheel deformation, and other faults are similar; in addition, for example, if the deadline of the wheel 3 is not exceeded, but the number of operating cycles exceeds the set threshold, it is also necessary to send maintenance inspection information to the host computer 10 through the controller 9.

[0038] The controller 9 includes a PLC controller and an MCU controller.

[0039] It also includes: a wheel condition detection device 6, which is used to detect the wheel 3 to obtain the operating status of the wheel; wherein the wheel condition detection device 6 can adopt a belt sintering machine trolley wheel bearing damage detection device disclosed in the patent document with publication number CN218381603U.

[0040] For example, the duration of wheel deformation failure does not exceed 3 times, but the wheel condition detection device 6 detects that the wheel 3 is deformed. The controller 9 sends information to the maintenance personnel through the upper computer 10 to remind the maintenance personnel to check the wheel. If the wheel is indeed deformed and the deformation is serious, the wheel 3 needs to be replaced. Other faults are similar and are not listed here.

[0041] It also includes: a lubricant adding robot 8, which is arranged at the rear end of the sintering trolley in the driving direction and the front end of the two-dimensional code recognition camera 7; Figure 1 The direction of the hollow arrow is the running direction of the sintering trolley. The lubricant adding robot 8 is arranged on the right side of the QR code recognition camera 7 ; the controller 9 sends a control instruction to the lubricant adding robot 8 to add lubricant to the wheel 3 .

[0042] For example: when the wheel condition detection device 6 detects that the wheel 3 has axial surface wear, the lubricant adding robot 8 adds lubricant to the bearing of the wheel 3; or when the wheel 3 reaches the end of the maintenance cycle of axial surface wear, the lubricant adding robot 8 adds lubricant to the bearing of the wheel 3.

[0043] The lubricant adding robot 8 can be arranged on both sides of the sintering trolley to add lubricant to the wheels 3 on both sides of the sintering trolley respectively; the lubricant adding robot 8 can adopt the wheel cleaning and oiling system of the sintering trolley disclosed in the patent document with publication number CN212319366U.

[0044] The system also includes a host computer 10 , which is electrically connected to the controller 9 , and through which the information of each sintering trolley and the maintenance information of the wheel 3 are intuitively displayed.

[0045] It also includes: a communication module, which is connected to the host computer 10. The communication module can be wired or wireless, such as a 4G or 5G communication module. The host computer 10 sends the information of the wheel to be maintained to the maintenance personnel, and the maintenance personnel checks and repairs the wheel 3 after receiving the information.

[0046] like Figure 2 In order to detect the circuit diagram of the maintenance system, the controller 9 adopts a PLC controller, the two-dimensional code recognition camera 7 and the host computer 10 are connected to the switch, and the switch is connected to the network of the PLC controller 9; wherein, the host computer 10 can also be replaced by an HMI operation screen; the two-digit code label contains the car number, the proximity switch 5 and the I0.0 of the controller 9, the host computer 10 detects the state of I0.0 in the controller 10, when a wheel 3 passes by the proximity switch 5, the I0.0 state of the controller 10 changes from 0 to 1, and when the host computer 10 detects that I0.0 is 1, the host computer 10 sends a shooting instruction to the two-dimensional code recognition camera 7, extracts the car number through the two-dimensional code label 2 and feeds it back to the host computer 10, and the host computer 10 obtains the number of the car 1 and obtains the corresponding number of the car 1. The relevant information of the two sets of wheels; when a QR code number is returned, it defaults to the first set of wheels 3 of the current car 1, and when no QR code information is returned, it defaults to the second set of wheels 3 of the last returned car 1. If no QR code information is returned for three consecutive times, it indicates that the equipment is abnormal; the upper computer 10 displays the number of running cycles of the wheels 3 of the current car 1, the last maintenance time, the last oiling time, the number of running cycles of the wheels 3 after oiling, etc.; when the last oiling time exceeds the deadline or the number of running cycles of the wheels 3 after oiling exceeds the threshold, the oiling start instruction is output through Q0.0, and after the oiling is completed, the completion instruction is fed back to the controller 9 through I0.1, and the controller 9 updates the current oiling completion time; when the maintenance time of the wheel 3 exceeds the deadline, the warning light prompts through Q0.1 of the controller 9.

[0047] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
