Transfer butt-joint locking device for aerospace vehicle

Abstract

The invention provides a transfer butt joint locking device for an aerospace vehicle. The device comprises a transfer erecting frame, a platform support and locking assemblies, wherein the transfer erecting frame is configured to erect the aerospace vehicle and put the aerospace vehicle on a walking device, the walking device provides advancing power to transport the transfer erecting frame, and alower surface of the transfer erecting frame includes a concave guide rail; the platform support is configured to support the transfer erecting frame transported by the walking device, the platform support is installed on one side of a launching pad, and the upper surface of the platform support includes a convex guide rail; and the locking assemblies are arranged on the transfer erecting frame and the platform support and are configured to lock the transfer erecting frame on the platform support. According to the transfer butt joint locking device for the aerospace vehicle, manpower is saved, butt joint efficiency is improved, and launching preparation time of the aerospace vehicle is shortened.

Description

technical field [0001] The invention relates to the field of launch and transfer of space vehicles, in particular to a transport docking locking device for space vehicles. Background technique [0002] With the rapid development of my country's aerospace industry, the test and launch mode of space vehicles has gradually appeared a "three-level" test and launch mode, that is, the launch mode of horizontal assembly, horizontal transfer, horizontal test, and vertical launch. Therefore, after the space vehicle is transferred to the launch pad, it is a very important link in the entire space vehicle launch process to reliably dock and lock and erect it to a vertical state. In a sense, it also determines the success or failure of the launch mission. [0003] Due to the different conditions of the launch site, there is a certain deviation in the flatness of the ground, and there is a straight line deviation in the driving of the transfer axis vehicle, which leads to certain diffi...

AI Technical Summary

Problems solved by technology

[0003] Due to the different conditions of the launch site, there is a certain deviation in the flatness of the ground, and there is a straight line deviation in the driving of the transfer axis vehicle, which leads to certain difficulties in the docking and positioning of the transfer vertical frame and the platform support, and the transfer vertical frame. The weight and size are relatively large. To ensure accurate docking positioning and locking, it takes a lot of manpower and time to adjust, which is not allowed in the entire launch mission process

[0004] At present, there is no case of horizontal docking and positioning of medium-sized liquid space vehicle launcher in China. Therefore, it is urgent to develop a new type of docking positioning and locking device to meet the docking positioning and locking requirements of the space vehicle transfer erector and platform support. question
