AI Technical Summary

Technical Problem

Traditional tamping machines have non-adjustable hammer height and frequency, severe wear on the lifting mechanism, low reliability of the transmission system, short hammer rod life, poor overall economy, and cannot adapt to changes in working conditions, resulting in poor uniformity of coal cake density and large fluctuations in coke quality.

Method used

Employing a gravity-balanced synchronous transmission system, combined with a flexible connection mechanism and multi-dimensional sensors, and through the separation design of the hammer lifting drive device and the clamp, the hammer lifting height and frequency can be adjusted in real time. It is also equipped with a hydraulic buffer and a fast-response drive device to enhance the flexibility and reliability of the equipment.

Benefits of technology

It extends the service life of the hammer drive device, improves the safety and reliability of the tamping machine, reduces spare parts consumption and maintenance costs, and enhances the uniformity of coal cake tamping and the stability of coke quality.
