Assembly line type thermal shock loading test device for thermal protection material of aerospace vehicle

The invention discloses an aerospace vehicle thermal protection material assembly line type thermal shock loading test device which comprises a three-temperature type heating bin, a first heating section, a second heating section and a third heating section are sequentially arranged in the three-temperature type heating bin from bottom to top, and the first heating section, the second heating section and the third heating section form a communicated vertical heating channel; an axial feeding mechanism is arranged at the bottom of the three-temperature type heating bin, and the axial feeding mechanism is driven by the axial feeding mechanism to move up and down; a lower feeding mechanism is arranged below the first heating section; and an upper discharging mechanism is arranged above the third heating section. The first heating section, the second heating section and the third heating section can heat the heating section to different set temperature gradients, the test piece can be rapidly heated to the preset
