Troubleshooting and repairing gearbox malfunctions
Generally speaking, it has high vehicle unbinding efficiency. Because the reducer is mechanical equipment, long-term continuous operation will inevitably lead to wear and tear, performance degradation, and easily cause slow action and prolonged action time, directly affecting the accuracy of vehicle speed control. Therefore, it is very important to timely detect reducer failures, perform maintenance, and monitor the action time of the reducer in real time.

Generally speaking, it has high vehicle unbinding efficiency. Because the reducer is mechanical equipment, long-term continuous operation will inevitably lead to wear and tear, performance degradation, and easy to cause slow action, prolonged action time, directly affecting the vehicle speed control accuracy. Therefore, it is very important to timely discover the reducer fault, carry out maintenance, and real-time dynamically monitor the action time of the reducer.
In the algorithm of the traditional speed control system, the delay time of the retarder control mechanism is fixed, that is, its braking time and release time are unchanged.
However, through the long-term application of the reducer, it is found that the action time of each reducer is different, showing discreteness; the action time of all reducers changes with the continuous use of the equipment, which is dynamic. The traditional speed control system has the disadvantage of lagging behind the dynamic reducer.
When the reducer performance decreases, the action time becomes longer, the control accuracy decreases, and the normal driving of the vehicle is affected. After the fault occurs, professionals can modify the computer software to improve the control accuracy of the control system. This method often needs to be repeated many times, affecting the normal use of the equipment and reducing the operation efficiency of the hump yard. If the monitoring equipment is developed to monitor the action time of the entire reducer in real time and dynamically, the speed regulation system can automatically modify the control parameters through self-learning and self-adaptation, improve the control accuracy, make the control intelligent, and greatly improve the performance of the speed regulation system.
After the speed control system sends a braking command to the reducer, the braking relay is energized at the t gear
1. Braking refers to the moment when the relay is energized as t.
2. Reducer braking time system. After the control system sends a release command to the reducer, the moment when the braking relay drops is t.
3. Relaxation means that the moment the relay is energized is t.
4. Then the pressure relief time of the reducer is T-slow, and T-slow is the action time of the reducer. Through real-time dynamic monitoring, the working condition of the reducer can be grasped in time. At the same time, the braking position and position of the reducer itself indicate the failure of the contact, so as to carry out scientific and comprehensive repair on site in time.
