The invention discloses a crawler belt sealing structure and a mounting method thereof. The crawler belt sealing structure comprises an outer caterpillar track section, an inner caterpillar track section, a supporting ring, a floating sealing ring, an outer sealing ring, an inner sealing ring, a pin sleeve and a pin shaft, and a hole and a counter bore are formed in the outer caterpillar track section; holes are formed in the inner caterpillar track sections; the supporting ring is arranged in the counter bore of the outer caterpillar track section, and a groove is formed in the supporting ring; the floating seal ring is installed in the groove and provided with an annular groove. The outer sealing ring is mounted in the annular groove of the floating sealing ring and is matched with the groove of the supporting ring to form an outer sealing layer; the inner sealing ring is arranged at the bottom of the groove of the supporting ring and abuts against the floating sealing ring to form an inner sealing layer. The pin bushes are mounted in holes of the left and right inner caterpillar track sections and are propped against the floating seal rings; according to the sealing structure, the outer-layer sealing layer and the inner-layer sealing layer are used in cooperation, and the sealing reliability is greatly improved.
