What should we do if the braking distance of Xiangtan mining electric locomotive does not meet the regulations?
During the operation of Xiangtan mining electric locomotive, if the braking distance does not meet the specified requirements, it may pose a potential threat to safety. In this case, timely measures must be taken to solve the problem to ensure that the braking performance of the electric locomotive meets the requirements. The following are some possible treatment methods:
1. Repair or replace accessories with excessive wear: Key components of the braking system, such as screws, nuts, pins, etc., if the wear exceeds the specified limit, will affect the braking performance. Therefore, it is important to repair or replace these accessories with excessive wear in a timely manner.
2. Correct the position of the hoist and connecting rod: The hoist and connecting rod are important components of the braking system. The abnormal position of the hoist and connecting rod will cause poor contact between the brake shoe and the wheel, thereby affecting the braking effect. Therefore, it is necessary to regularly correct the hoist and connecting rod to ensure that their position is correct and that the brake shoe can have good contact with the wheel when working.
3. Overloading is strictly prohibited: Overloading is an important reason for the increase in braking distance. According to the provisions of the "Coal Mine Safety Regulations", mining electric locomotives must be carried according to the prescribed traction load during operation, and overloading is strictly prohibited to ensure the effective performance of braking performance.
4. Replace the brake shoe and adjust the gap: The brake shoe is an important friction element in the braking system, and its wear directly affects the braking performance. If the brake shoe is found to be severely worn, it should be replaced in time, and the gap between the brake shoe and the wheel tread should be adjusted. The gap is usually required to be 3-5mm, and the contact area is not less than 60%.
5. Replace or add an electrical auxiliary braking system: If the braking distance still does not meet the specified requirements after taking the above measures, you can consider replacing a braking system with better braking effect or adding an electrical auxiliary braking system. The electrical auxiliary braking system can improve the braking effect and reduce the wear of the brake shoe.
In summary, when the braking distance of Xiangtan mining electric locomotives does not meet the specified requirements, corresponding treatment measures must be taken in time. The braking performance of the electric locomotive can be effectively improved and the operation safety can be ensured by repairing or replacing the worn parts, correcting the position of the hoist and connecting rod, prohibiting overloading, replacing the brake shoes and adjusting the clearance, and replacing or installing the electric auxiliary braking system. At the same time, regular maintenance and inspection work should be carried out to ensure the good working condition of the electric locomotive braking system to prevent the potential safety hazards caused by excessive braking distance.
