Background

In the prior art, a rocket in a three-level test launch mode is generally adopted, and before being launched, a erecting device erects the rocket from a horizontal state to a vertical state on a launching pad, and is placed on the launching pad, so that the conversion of a rocket body from the horizontal state to the vertical state is completed.

When the rocket is erected by adopting the vertical arm, a multi-stage oil cylinder is usually used for jacking the rocket-carrying vertical arm from a horizontal state to a vertical state. In order to ensure the stability of the rocket erection, a reinforced concrete foundation is generally poured on a launching pad, and a steel plate is pre-embedded and used for installing an erection arm rotary support and an erection oil cylinder lower support. The rotary hole at the lower end of the vertical arm is connected with the rotary support of the foundation through a rotary shaft. The rod ring at the upper end of the erection cylinder is connected with the cylinder upper support of the erection arm through an upper rotating shaft, the lower end of the erection cylinder is also connected with the cylinder lower support of the foundation through a cylinder lower support lug, and the erection and the lowering of the erection arm with a rocket are realized through the extension and retraction of the erection cylinder.

After the rocket is erected, the rocket is placed on a launching pad, and the rocket is vertically supported and fixed by using the launching pad. In order to ensure the supporting stability of the rocket under wind load, the middle-sized and large-sized rocket is generally poured with a supporting leg foundation of a launching platform at a launching station, a steel plate is embedded, and a supporting leg disc of the supporting leg is fixed on the foundation by using foundation bolts. The small rocket launching mode is flexible, and the launching pad can be vehicle-mounted or movable and does not need to be fixed on a foundation.
