Sea launch platform for rocket and method for erecting rocket

Abstract

The present invention relates to a rocket sea launching platform and a method for erecting rockets. The launching platform includes a fixed frame, an erecting frame, an insulation cabin and an erecting platform. The erecting frame is connected with the fixed frame through a rotary shaft mechanism, and also includes a Erecting device and buffer device, the erecting device includes a winch and an erecting wire rope, the hoist is fixed on the fixed frame, the left end of the erecting wire rope is connected with the hoist, and the right end of the erecting wire rope goes around the erecting pulley and the erecting frame on the fixed frame The buffer device includes a support arm, a buffer pulley, a reversing pulley, a limit rod, a buffer wire rope, a pendant and a docking arm, which has the advantages of simple structure, safety, reliability, and strong adaptability, and can reduce docking. Difficult to operate, to avoid stall phenomenon during the erection process. The method of erecting the rocket has the advantages of simple process, less difficulty in manipulation and high safety.

Description

technical field [0001] The invention relates to a rocket launching stand, in particular to a rocket sea launch stand and a method for erecting a rocket by using the launch stand. Background technique [0002] In the field of rocket launching, the launch platform is usually designed to be composed of a fixed frame and a vertical frame, and the two are hinged through the rotary shaft, so that the quiver assembly (the combination of the rocket and the launch tube) is hoisted and fixed on the vertical frame. on the frame, and through the erecting system, the erecting frame is rotated around the rotary axis to complete the erecting action of the rocket. Compared with land launch, sea launch has attracted more and more attention due to its advantages of low launch cost and low launch energy loss. For land launch platforms, hydraulic cylinders are usually used as the actuators of the erection system, because the hydraulic cylinders can provide both pulling force and thrust force, ...

AI Technical Summary

Problems solved by technology

However, for the sea launch platform, due to the limitation of the distance between the rotary shaft and the space of the launching ship, the hydraulic cylinder is no longer suitable as the execution part of the erection system, and the hydraulic cylinder cannot realize redundant backup, which is less safe

The hoist is usually used as the execution part of the erection system on the sea launch platform, which can improve safety through redundant design, but the following problems still exist in the application of the existing sea launch platform: the erection cable can only It provides one-way pulling force, but cannot provide reverse thrust. During the erection process, when the overall center of mass of the erection frame and quiver assembly crosses the vertical plane where the rotary axis is located, there is a stall phenomenon, which affects the safety of the rocket and the launch platform; The docking of the fixing frame and the erecting frame is not only difficult to operate, time-consuming and labor-intensive, but also poor in safety
