Description

Technical Field

[0001] The present invention relates to the technical field of fixed launch platform structures, and in particular to a fixed launch platform structure. Background Art

Since this test and launch mode does not require tall vertical factories and complex service towers, the rocket-ground interface can be kept unchanged during the transition process, shortening the occupancy time of the launch area, and is increasingly used. The fixed launch platform, as one of its important equipment, is mainly responsible for the tasks of rocket docking, receiving, landing, supporting, guiding, and lifting. The receiving structure, as an important subsystem of the fixed launch platform, can receive and land the rocket body after the erection frame is erected in place. After the landing is in place, the receiving mechanism does not bear the load force; after the launch is completed, the receiving mechanism can be lifted in a reverse process to cooperate with the docking of the mobile launch platform and the erection frame; when not working, the receiving mechanism is placed in the fixed launch platform with an external protective cover to avoid being affected by the external environment. The traditional receiving mechanism completely draws on the structure of other launch platform support arms, and adopts a "drive module + deceleration module + receiving module" structure. The drive module is an electric motor or a hydraulic motor, the deceleration module is a single reducer or multiple reducers in series, and the receiving module is mainly screws and nuts.
