Buffer device and buffer control method for rocket flexible cable erection system

Abstract

The invention relates to a buffer device and a buffer control method for a rocket flexible steel cable erecting system. The buffer device includes a buffer mechanism and a docking mechanism. The buffer mechanism includes a support arm, a guide pulley, a reversing pulley, a limit lever, a traction rope and a pendant The support arm is fixed on the fixed frame, the support arm is fixed with two limit plates, and the two limit plates are provided with limit card slots, the guide pulley is installed on the fixed frame, the reversing pulley is installed on the support arm, and the guide pulley Corresponding to the reversing pulley, it is located on the left and right sides of the limit plate. The limit rod is located in the limit slot of the limit plate and connected to one end of the traction rope. The other end of the traction rope bypasses the reversing pulley, the guide pulley and the pendant. Connection; the docking mechanism includes a docking arm fixed on the erecting frame, two docking plates are fixed on the upper end of the docking arm, and a docking card slot is provided on the upper side of the two docking plates. The utility model has the advantages of simple structure, smooth action and good cushioning effect. The buffer control method has the advantages of simple process and easy implementation.

Description

technical field [0001] The invention relates to a buffer device, in particular to a heavy object buffer device used in a rocket flexible cable erection system and a buffer control method thereof. 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. For the traditional land launch platform, the actuator of the erection system usually adopts a hydraulic cylinder, because the hydraulic cylinder is a two-force rod structure, which can provide both pulling force and thrust force, and the speed can be controlled by the hydraulic damping buffer structure to achieve...

AI Technical Summary

Problems solved by technology

As for the offshore 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 actuator of the erection system; and the dynamic environment at sea is more complex, the hydraulic cylinder cannot realize redundant backup, and the safety is poor

In view of this, the electric winch flexible steel cable erecting system has become an optional method, but this erecting system has the following problems in the implementation and application: because the flexible steel cable can only provide one-way pulling force and cannot provide reverse thrust, the lifting During the vertical process, when the overall center of mass of the erection stand and the quiver assembly crosses the vertical plane where the rotary axis is located, a stall phenomenon will occur. If it is not controlled, it will seriously affect the safety of the rocket and the launch stand. If a mechanical limit is adopted, it will Can create impact issues, as well as cause damage to quiver assemblies or launch pads
