Supporting and pressing device for rocket arrow foot and rocket launching platform

Abstract

The invention discloses a rocket foot supporting and pressing device and a rocket launching platform, comprising an actuator, a pulling part, a pressing part, a fixing part and an arrow foot supporting seat; the actuator passes through the pulling part Connected with the pressing piece, the arrow foot support base is used to support the rocket arrow foot and is located on a side close to the pressing piece, the pressing piece is rotatably arranged on the arrow foot support base, The actuator is used to pull the pressing part to rotate through the pulling part, so as to realize the locking and disengagement of the arrow foot of the rocket; the outside of the pulling part is also provided with a guiding and positioning assembly, and the guiding and positioning assembly is at least It is used to guide the traction member when the traction member is driven by the actuator, one end of the fixing member is fixedly connected with the guide positioning assembly from one side of the guide positioning assembly, and the other end is The utility model is used for connecting with the launching platform body, and has the advantages of reasonable design, safety and reliability, and convenient control, etc. compared with the prior art.

Description

technical field [0001] The invention relates to the field of rockets, in particular to a rocket foot supporting and pressing device and a rocket launching platform. Background technique [0002] With the rapid development of the aerospace industry, various technologies related to rockets have also achieved rapid progress. When the launch vehicle adopts the "three-flat" test launch mode, the rocket will shake in the vertical state due to the wind load, which will bring great safety hazards to the parking and filling of the rocket. Therefore, the rocket feet must be supported reliably fixed. The traditional method is to install a windproof bolt or a windproof pressure plate at the arrow foot, so that it must be manually removed on site when the rocket is filled with propellant. Because the propellant is a flammable and explosive liquid, it brings great potential safety hazards in the process of manual removal. [0003] Therefore, how to provide a reasonable design, safe and...
