Abstract

The invention provides a high-speed ejection buffer device. After an ejection object is ejected at a high speed, a traction rope drives a rotating shaft to rotate, a moving nut moves in the axial direction relative to a limiting groove to squeeze a spring, the spring then compresses a friction plate group, so that kinetic energy of the ejection object is converted into internal energy to dissipatethrough a friction work mode, the impact force is gently slowed down, and the rope is effectively prevented from being snapped. According to a transmission mode of the high-speed ejection buffer device, the friction force can be gradually increased from zero until the spring is completely compressed, the friction force reaches the peak, and the friction force can be automatically adjusted; a winding drum is arranged, an 8-shaped winding mode utilizes the friction force between a rope and a rope, the rope and a winding shaft and the rotating shaft, the rope is firmly fixed, so that the terminal line fixing mode is reliable; and a collector ring is nested in the rotating shaft to prevent signal wires inside the rope from being tangled when the rotating shaft rotates at high speed.

Description

technical field [0001] The invention relates to a buffer device, in particular to a high-speed ejection buffer device. Background technique [0002] In the field of ejection or aerospace, the projectile ejected at high speed and the base are buffered and decelerated by connecting ropes. In actual use, due to the excessive speed of the projectile, it is easy to break the rope. Contents of the invention [0003] In view of this, the present invention proposes a high-speed ejection buffer device that can effectively prevent the rope from breaking. [0004] The technical solution of the present invention is achieved in the following way: the present invention provides a high-speed ejection buffer device, which includes a rope (1), and also includes a base (2), a rotating shaft (3), a sleeve (4), several first One friction plate (5), several second friction plates (6), limit groove (7), moving nut (8) and spring (9), the rotating shaft (3) is rotatably connected with the base...
