Description

Technical Field

[0001] The utility model relates to assembly detection of military equipment, in particular to a simple projectile chambering and unchambering device. Background Art

[0002] After assembly, some missiles need to be loaded into storage and shipping boxes for storage, transportation, and launch. The chambering and unchambering of missiles impose additional safety requirements on the alignment of the missile's external shape with the storage and shipping box's internal structure, the missile's hoisting, and the smoothing of the bore. Traditionally, chambering and unchambering of missiles involves hoisting the missile using a crane, manually aligning it, and then pulling it into and out of the storage and shipping box using a tow rope. Before the missile enters the storage and shipping box, manual alignment makes it difficult to align the missile with the box's bore, making it prone to getting stuck in the bore. Furthermore, as the missile moves within the storage and shipping box, the force applied to the tow rope is difficult to maintain consistency with the barrel, potentially causing damage to the bore and compromising the accuracy and safety of the missile launch. Therefore, it is imperative to design a low-cost, safe, and efficient missile chambering and unchambering device. Summary of the Invention

[0003] Aiming at the problem that it is difficult to engage and un-bore a projectile using manual alignment, which easily damages the straightness of the guide rail and affects the accuracy and safety of projectile firing, the utility model provides a simple projectile engaging and un-bore device.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a simple projectile chambering and debarking device, including a box-rail adapter, a guide rail sling, and a guide rail. The box-rail adapter is adapted to the box opening structure of the storage and transportation box. The guide rail sling is fixedly arranged on the guide rail, and a plurality of circular holes for threading slings are provided on the guide rail sling.

[0005] The front end of the guide rail is provided with two fastening screws for fixing the projectile body to prevent the projectile body from sliding when the chamber is closed or unbarred.

[0006] The box rail adapter is made of 35CrMnSiA and has 16 threaded holes around it for installation and fixation at the box opening for storage and transportation via hexagon socket screws.

[0007] The utility model adopts the above technical solution to design a simple projectile chambering and unchambering device, and its beneficial effects are:

[0008] 1. It solves the problem of aligning the projectile body with the storage and transportation box before chambering, and bears the problem of high mass load of the projectile body;

[0009] 2. Ensure the linearity and uniformity of the force applied to the projectile when it moves in the chamber, effectively improving the safety of the projectile in the chamber and the efficiency of the projectile in the chamber and out of the chamber;

[0010] 3. The utility model has low cost, low requirements on the working environment, and simple operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following is a further detailed description of a simple projectile body chambering and unchambering device of the present invention in conjunction with the accompanying drawings.

[0015] The utility model is a simple projectile chamber closing and unchambering device, see Figures 1 to 3 , including a box rail adapter 1, a guide rail hanger 2, a guide rail 3, and a hexagon socket fastening screw 4. The box rail adapter 1 is made of 35CrMnSiA and has 16 threaded holes around it, which is compatible with the structure of the storage and transportation box opening. It can be installed and fixed at the storage and transportation box opening by means of hexagon socket screws, so as to facilitate the connection between the guide rail 3 and the storage and transportation box. There are two fastening screws 4 for fixing the projectile at the front end of the guide rail 3, which are used to prevent the projectile from sliding when the barrel is closed or unbarred. The guide rail hanger 2 is processed using T-shaped steel, and there are eight through holes on it that are drilled according to the position of the guide rail 3 holes, and are connected and fixed to the guide rail 3 with screws. Twenty-five circular holes are evenly distributed on the upper end of the guide rail hanger 2. The position of the sling can be moved according to the center of mass of the projectile to ensure smooth movement of the projectile during lifting. When closing and unbarring, the projectile can be slowly and evenly pushed in and out of the barrel through the guide rail 3.

[0016] The specific use process of this utility model is as follows:

[0017] When closing the chamber, first install and fix the box-rail adapter 1 on the box opening for storage and transportation, then use the crane to connect the guide rail hanger 2 and guide rail 3 to the box-rail adapter 1 and fix them with screws. At the same time, loosen the fastening screw 4 at the front end of the guide rail. Use the crane to manually place the projectile lifting ear on the guide rail 3, tighten the fastening screw 4 to prevent the projectile from sliding backward, and finally manually push it into the chamber evenly.

[0018] When unloading, first install and fix the box rail adapter 1 on the box opening of the storage and transportation box, then use the crane to connect the guide rail hanger 2 and the guide rail 3 to the box rail adapter 1, and fix them with screws. At the same time, loosen the fastening screw 4 at the front end of the guide rail. At the other end of the storage and transportation box, push the projectile evenly by hand so that the projectile part contacts the guide rail 3, then pull the projectile evenly on one side of the box rail adapter 1 so that the front and rear ears are completely inserted into the guide rail 3, tighten the fastening screw 4 to prevent the projectile from sliding backwards, and the unloading is completed.
