The invention relates to the technical field of recovery devices, and discloses a heavy carrier rocket vertical recovery device which comprises a rocket body, four evenly-distributed landing legs are arranged on the lower portion of the outer surface of the rocket body, each landing leg comprises a main supporting column, an auxiliary supporting column and a foot pad, and the top end of each main supporting column is hinged to the outer surface of the rocket body; the top of the auxiliary supporting column is hinged to the outer surface of the arrow body, the bottom end of the main supporting column is hinged to the bottom end of the auxiliary supporting column, the top of the foot pad is hinged to the outer surface of the auxiliary supporting column, the main supporting column comprises an end cover, a first-stage sleeve, a second-stage sleeve, a third-stage sleeve and a hydraulic buffer, and the auxiliary supporting column comprises a first hinged end and a second hinged end. The first hinge end is hinged to the outer surface of the arrow body. When the device is used, the main supporting column can be conveniently folded in the auxiliary supporting column through the auxiliary supporting column in the shape of the rectifying shell, the situation that an independent rectifying cover is designed on the outer side of the rocket body is avoided, and the structural weight of the rocket is greatly reduced.

    本发明涉及回收装置技术领域,且公开了一种重型运载火箭垂直回收装置,包括箭体,所述箭体外表面下方设置有四个均匀分布的着陆腿,所述着陆腿包括主支柱与辅助支柱和足垫,所述主支柱顶端与所述箭体外表面铰接,所述辅助支柱顶部与所述箭体外表面铰接,所述主支柱底端与所述辅助支柱底端铰接,所述足垫顶部与所述辅助支柱外表面铰接,所述主支柱包括端盖、一级套筒、二级套筒、三级套筒与液压缓冲器,所述辅助支柱包括铰接端一与铰接端二,所述铰接端一与所述箭体外表面铰接;该装置在使用时通过整流外壳形状的辅助支柱便于把主支柱收拢于辅助支柱内,避免了在箭体外侧设计单独的整流罩,且大大降低了火箭的结构重量。
