Description

Technical Field

[0001] The invention relates to a projectile, in particular to a large projectile chamber closing and de-chambering device. Background Art

[0002] As an important component of the weapon system, the projectile launching technology plays a vital role in the survivability and combat effectiveness of the projectile weapon. The launching technology directly affects the launching accuracy, combat capability, survivability, supply method and development cost of the projectile weapon system, and is the premise for determining the type and configuration of combat equipment. The projectile launching system refers to a special device used to support the projectile and determine its direction, carry out launch preparation and implement launch. The projectile launching is the process of pushing the projectile along the guide rail in the launch box through the projectile launching system by the booster engine installed at the tail of the projectile. Therefore, the chambering and unbarring of the projectile is also a very important task. For large projectiles, the guide rails for the chambering of the projectile and the launch box are long, and the projectile is slightly misaligned, which brings great difficulties to the chambering and unbarring of the projectile. The straightness of the guide rails is easily damaged, affecting the accuracy and safety of the projectile launching.

[0003] Existing technology projectile body chamber closing and de-chambering device such as Figure 1 As shown, the projectile 3 is lifted by a crane 1, manually aligned, and the projectile 3 is pulled into and out of the launch box 4 by a traction rope 2. Before the projectile 3 enters the launch box 4, due to manual alignment, it is difficult to ensure that the projectile 3 and the inner bore of the launch box 4 are in the same straight line, which makes it easy for the projectile 3 to get stuck in the bore. During the movement of the projectile 3 in the launch box 4, it is difficult to ensure that the force on the traction rope 2 is consistent with the inner bore of the launch box 4, which can easily cause damage to the guide rail in the bore, affecting the accuracy and safety of the launch of the projectile 3. In addition, the current effect of the operation of the crane 1 is also likely to affect the detonation system of the projectile 3, reducing the safety of the projectile 3.
