Buffering device and buffering control method for rocket flexible steel cable erecting system

Abstract

The invention relates to a buffering device and buffering control method for a rocket flexible steel cable erecting system. The buffering device comprises a buffering mechanism and a butt joint mechanism, wherein the buffering mechanism comprises supporting arms, guide pulleys, reversing pulleys, a limiting rod, a traction rope and a pendant; the supporting arms are fixed on a fixed frame, and thesupporting arms are fixedly connected with two limiting plates; the two limiting plates are provided with limiting clamping grooves; guide pulleys are mounted on the fixed frame and the reversing pulleys are mounted on the supporting arms; the guide pulleys and the reversing pulleys are correspondingly arranged on the left sides and the right sides of the limiting plates; the limiting rod is arranged in the limiting clamping grooves of the limiting plates and is connected with one end of the traction rope, and the other end of the traction rope bypasses the reversing pulleys and the guide pulleys to be connected with the pendant; and the butt joint mechanism comprises butt joint arms fixed on a erecting frame, two butt joint plates are fixed at the upper ends of the butt joint arms, and butt joint clamping grooves are formed in the upper sides of the two butt joint plates. The buffering device has the advantages of being simple in structure, stable in action and good in buffering effect. The buffering control method has the advantages of being simple in flow and easy in 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
