A driving device for automatic synchronous unlocking of folding wings

Abstract

The invention provides a folding fin automatic and synchronous unlocking driving device, which consists of four sets of push rod mechanisms, four lug bosses, a rotary rolling way inner ring, a rotary rolling way outer ring, a gear and a motor, wherein the four lug bosses are uniformly distributed and fixed on the rotary rolling way outer ring; the motor is fixed on a launching pad; the gear is arranged on a motor rotating shaft, and is engaged with a gear of the rotary rolling way outer ring. The motor works and drives the gear to rotate; the gear drives the rotary rolling way outer ring to rotate; then, the lug bosses rotate along with the rotary rolling way outer ring, when the lug bosses are under the push rod mechanisms; the lug bosses upwards prop push rods; the push rod does vertical and upward movement to reach a folding pin contact point; folding pins are driven to be unlocked; the four sets of push rod mechanisms simultaneously operate, so that the automatic and synchronous unlocking of four folding pins is realized.

Description

technical field [0001] The invention belongs to the technical field of rocket launching equipment, and in particular relates to a driving device for automatic synchronous unlocking of folding wings. Background technique [0002] At present, at home and abroad, in order to make the rocket launcher miniaturized and the transportation and storage simple and convenient, the wings of the rocket adopt a folded structure. When the rocket is transported and stored, the wings are in a folded state to reduce the wingspan. When it is time to launch, after the rocket is erected in place, it needs to rely on the axial force to drive the folding wing mechanism to complete the automatic deployment of the wing surface to the normal position, and then implement the ignition and launch. At present, the rocket is usually more than 1.5 meters away from the ground after being erected on the launcher. The method of driving and unlocking the 4 folding wings on the launcher by personnel on the laun...

AI Technical Summary

Problems solved by technology

At present, the rocket is usually more than 1.5 meters away from the ground after being erected on the launcher. The method of driving and unlocking the 4 folding wings on the launcher by personnel on the launcher will undoubtedly increase the safety risk and greatly increase the launch preparation time. , greatly restricting the demand for rapid launch of rockets
