Solution to the Defects in the Support Points of Explosion-proof Hand-Pulled Gourd Trolleys

The support points of explosion-proof hand-pulled gourd trolleys play a crucial role in ensuring the stability and safety of the equipment. However, defects in these support points can lead to operational issues and safety hazards. Below is an analysis of common defects, their causes, and effective solutions:

1. Common Defects in Support Points

Instability in Transmission: Traditional hand-pulled gourd trolleys often use a two-point support system for the transmission shaft. This design can cause instability during transmission, as the shaft operates like a cantilever beam, leading to unbalanced loading.

Braking Failure: Due to gaps between the transmission shaft and support points, the brake surfaces may not remain parallel, especially when parts are worn. This can result in braking failure.

Gear Damage: In the absence of adequate support at the gear end, impact loads can exacerbate unbalanced transmission, leading to gear damage.

2. Causes of Defects

Design Flaws: The two-point support system, while cost-effective, compromises stability and increases the risk of component failure.

Component Wear: Over time, parts such as pins, chains, and gears may wear out, affecting the alignment and function of the support points.

Improper Operation: Overloading, slant lifting, or other misuse can exacerbate stress on the support points, leading to premature failure.

3. Solutions to Defects

Upgrade Support Structure: Transitioning to a three-point support system can significantly improve stability. This involves adding an extra support point to the transmission shaft, reducing the cantilever effect and enhancing load distribution.

Regular Maintenance: Implement a routine inspection and maintenance schedule to identify and replace worn components promptly. Pay special attention to pins, chains, and gears, ensuring they are lubricated and functioning correctly.

Operator Training: Train operators on proper usage techniques, emphasizing the importance of adhering to load limits and avoiding slant lifting. This can prevent many operational errors that lead to support point defects.

Use of High-Quality Components: Replace worn parts with high-quality, original equipment manufacturer (OEM) components to ensure compatibility and reliability.

4. Expert Recommendations

Periodic Inspections: Conduct regular inspections of the trolley’s support points, looking for signs of wear, misalignment, or damage.

Lubrication: Keep all moving parts well-lubricated to reduce friction and wear.

Avoid Overloading: Always operate within the trolley’s specified load capacity to prevent excessive stress on the support points.

Professional Repairs: For major defects or repairs, consult a professional technician to ensure the work is done correctly and safely.

5. Conclusion

By addressing design flaws, implementing regular maintenance, and providing adequate operator training, the defects in the support points of explosion-proof hand-pulled gourd trolleys can be effectively mitigated. This not only enhances the safety and reliability of the equipment but also extends its operational lifespan, ensuring efficient and secure material handling in hazardous environments.
