Safety protection device for missile hanging vehicle

Abstract

The invention provides a safety protection device for a missile hanging vehicle. The missile hanging vehicle comprises an upper frame, a lower frame and a scissor lifting arm set. The scissor liftingarm set comprises a first lifting arm and a second lifting arm which are hinged to each other. One end of the first lifting arm is hinged to the upper frame in a sliding mode through a safety protection device. The safety protection device comprises a guide sliding groove fixed to the upper frame and a sliding block connected into the guide sliding groove in a sliding mode; the first lifting arm is hinged with the sliding block; a retaining strip is arranged on the groove wall of the guide sliding groove; a plurality of retaining grooves with upward openings are formed in the retaining strip in the length direction of the retaining strip; a guide inclined plane is arranged on the groove wall of one side of the retaining groove; a connecting vertical plate is arranged on the sliding block;the connecting vertical plate is horizontally and elastically connected with a retaining rod through an elastic mechanism; and one end of the retaining rod penetrates through the connecting vertical plate and is provided with an inclined plane with the same inclination direction as the guide inclined plane. According to the safety protection device, it can be guaranteed that the upper frame stopsfalling in case of emergency, the purpose of self-locking is achieved, and therefore the safety of operators and hung objects is protected.
