Abstract: In view of the problems of "unbroken and constantly pulled" in subway train body demolition, and the limitations of equipment used in special rescue environment, this paper carried out research of new equipment for subway train body demolition rescue. A high-strength and high-efficiency self-feedback intelligent control of subway train body dismantling equipment was developed, which innovative adopted the principle of high-precision machine tool technology, designed and installed high-efficiency cutting power head with the x-axis direction can control the feed rate, and designed the saw blade speed-feed rate force feedback computer control system. It achieves rapid and safe demolition of high-strength train body under extreme circumstances, opens up valuable escape channels for trapped people and reduces casualties.

Key words: fire protection, subway train body, demolition equipment, special rescue
