With the help of computer graphics processing technology, based on analysis of operating conditions of the sintering trolley and its wheel axle oiling characteristics to identify and position the trolley wheels, this kind of six (three)-axis robot is designed to cooperate with visual positioning and visual judging system to complete wheel oiling and damage assessment.
Note: In this workstation, the robot is guided by vision technology to move and refuel synchronously with the trolleys, and the trolley does not stop in the process.
The existing method of oiling the sintering trolley is to manually fill the sintering trolley with oil when it is not in operation, and then perform cleaning and maintenance after operation.
However, with this method, dust such as iron powder and iron filings caused during the transmission process of the sintering trolley, as well as the dry matter formed by mixing the dust and dust with the lubricating oil under high temperature conditions, are likely to cause the lubricating oil to flow along the oil injection process during the lubricating oil injection process. If the wheel oil cup in the opening enters the bearing assembly, it will not only easily cause the bearing assembly to be insufficiently lubricated, but also cause wear of the wheel axle;
Moreover, when the wheel system of a sintering trolley in a hot operating environment is worn, it is more likely to cause deformation of the wheel components of the sintering trolley, accelerate wheel axle wear, and eventually lead to wheel locking, and the wheel axle must be replaced.
Moreover, since the wheel axle and the axle sleeve have an interference fit, and the axle sleeve is welded to the trolley body, it is usually necessary to lift the entire sintering trolley off the track to replace a new sintering trolley, which makes the replacement of the wheel axle time-consuming. longer.
At the same time, due to the interference fit between the wheel axle and the bushing, destructive forceful disassembly is generally used in the process of replacing a worn wheel axle. Strong disassembly will not only further damage the wheel axle, but also damage the axle sleeve, which in turn will Resulting in increased repair costs for wheel axles.
We provide a wheel cleaning and oiling system for the sintering trolley, which can complete the automatic cleaning and automatic oiling of the sintering trolley wheel system without changing the existing sintering trolley wheel structure to prevent the sintering trolley from being hot and dusty. The diffuse working environment causes wear and tear on the sintering trolley wheel system, and the equipment modification cost is low, and the equipment application and debugging flexibility is high.
1. Online refuelling does not affect the operation of the original system on-site and can adapt to real-time speed changes on-site.
2. Automatically cleans the oil filling port, effectively preventing and reducing dust such as iron powder and iron filings, as well as dry matter formed by mixed dust and lubricating oil from adhering to the oil filling port and entering the wheel axle and bearing components through the oil filling port, causing wear.
3. The position of the refuelling port is automatically collected visually and the displacement of the refuelling head is automatically calibrated; the structure is compact, the movement is flexible, convenient and practical, and it is capable of online automatic refuelling and lubrication of the sintering trolley wheels.
4. Use small amounts of oil multiple times to prevent excessive oil spillage. The overall oil filling time is controlled to 20 to 30 seconds. The wheel’s lack of oil, refilling and clogging status can be judged through flow and oil pressure, and corresponding warnings can be given.
5. When refuelling, consider adding an oil receiving box at the refuelling nozzle to ensure that the wheels on site are clean.
6. Each wheel is marked with a QR code to ensure real-time monitoring of the entire trolley wheel status and wheel life cycle recording. If a wheel or trolley needs to be replaced, the corresponding wheel can be entered into the system using an add-on method to ensure the uniqueness of the wheel identification.
7. Detection of wheel defects and bearing deformation can be added.
8. The system keeps the refuelling record of each wheel, and wheel status, and can trace the original data.
9. A thermal infrared camera can be added to monitor the temperature of the wheels in real time and monitor abnormal changes in the wheels of the trolley.
