Carrier rocket erecting launching system and carrier rocket erecting launching method

The invention relates to a carrier rocket erecting launching system which is characterized in that the carrier rocket erecting launching system comprises a rotary table assembly, a bottom leveling assembly, a suspension releasing device and a carrier rocket, and the suspension releasing device can lock the carrier rocket, keep the carrier rocket in a vertical state and rapidly release the carrier rocket during launching. According to the carrier rocket erecting launching system, the tedious fixing and installing process is omitted in the launching preparation stage, a fixing device at the bottom of the carrier rocket does not need to be manually dismantled before launching, the launching preparation time is remarkably shortened, the launching efficiency is improved, and due to the fact that manual close-range operation is not needed, the launching efficiency is improved. And the operation safety before the carrier rocket is launched is improved. The invention further provides a carrier rocket erecting launchi
