Description

Technical Field

[0001] The utility model relates to the technical field of ammunition, and in particular to a projectile device. Background Art

[0002] At present, the general method of conducting a projectile test is to place the assembled test projectile on the side wall of a solid building at an angle, and place bricks, rubble, construction waste, etc. under the projectile for support, and then stand it upside down on the ground at a certain angle, use a detonator to detonate the electric ignition head, and then ignite the projectile charge in the test projectile to complete the projectile test. Although the current projectile test method is simple, it has several disadvantages: since the test projectile needs to be tested at a certain projectile angle, there is no reliable and suitable support under and in front of the projectile, and the projectile is in a free state, resulting in the projectile being tipped over and strung due to the projectile force of hundreds of thousands of Newtons during the projectile process, causing the projectile to change its direction, which in turn makes the projectile's flight direction unpredictable, creating safety hazards and causing the projectile velocity to be unable to be correctly measured and calculated.

[0026] The utility model is further explained and illustrated below in conjunction with the accompanying drawings.

[0027] The projectile device of the utility model is mainly composed of a base assembly, a load-bearing cone assembly, a screw assembly, etc. The structure of the projectile device is as follows Figure 1 , Figure 2 shown.

[0028] Among them, the base assembly consists of a base 3, a rear base plate 1, a front base plate 17, 5 square steel pipe cross beams 19 of the same specifications and lengths, 2 angle iron longitudinal beams 21 of the same specifications and lengths, an upper base plate 2, 5 handles 23, 10 handle rings 24 and 4 rotating shaft supports 15. One end of two angle iron longitudinal beams 21 is aligned and parallel, four square steel tube cross beams 19 are longitudinally arranged side by side at one end of the two longitudinal beams 21 and welded to the contact part between the cross beams 19 and the longitudinal beams 21, and the upper bottom plate 2 and the rear bottom plate 1 are aligned and welded in the upper and lower directions of the four square steel tube cross beams, respectively. The fifth cross beam 19 is welded to the front bottom plate 17 at the other end of the longitudinal beam 21 and below it, and two rotating shaft supports 15 are welded above it, and the remaining two rotating shaft supports 15 are welded in the middle position of the two longitudinal beams 21. The base 3 is placed in the pre-determined positioning plane of the upper bottom plate 2 and welded to ensure that the base 3 is on the center line of the projectile device. According to the mass distribution of the projectile device, 10 handle rings 24 are welded in groups of two on the longitudinal beams 21 and the upper bottom plate 2, and the handles 23 are assembled before welding, as shown in Figures 3 (a) and 3 (b). The main function of the base assembly is to provide stable support and fix other components. The angle iron longitudinal beam 21 determines the horizontal baseline for the base assembly. In order to balance the projectile strength and overall weight of the projectile device, the cross beam is made of square steel pipe. The rear bottom plate 1 and the upper bottom plate 2 are used to make the base 3 evenly stressed. The four shaft supports 15 support and fix the front shaft 25 and the rear shaft 22 (when conducting a large angle projectile test, the rear shaft 22 is enabled). The handle 23 rotates freely in the handle ring 24, which provides convenience for loading, unloading and moving.

[0029] The load-bearing cone assembly is composed of a load-bearing shaft 20, a load-bearing cone 5, a semicircular support 6, and a concave connector 7. The contact parts of each part are spot welded. Figure 4 As shown. The main function of the load-bearing cone assembly is to support and fix the test sample, adapt to a variety of test samples of different calibers and lengths, and cooperate with the screw assembly to adjust the angle. The load-bearing shaft 20 is embedded in the base 3 and can rotate flexibly. The two ends are fixed by baffles 4. The load-bearing cone 5 and the semicircular support 6 jointly support the test sample. The concave connector 7 is welded at an appropriate position below the semicircular support 6 to provide a fulcrum for assembly with the screw assembly.

[0030] The screw assembly consists of an inner screw 10, an outer screw 11, a rotor 14, a screw cap 9, a plurality of balls 13, and a convex connector 8. The inner screw 10 is screwed into the outer screw 11. The rotor 14 coated with thread fastening glue is screwed into the inner thread end of the inner screw. Before screwing in, the screw cap 9 is inserted into the rotor 14. The convex connector 8 has a plurality of balls 13 for reducing rotational friction. The convex connector 8 is threadedly connected to the screw cap 9. Figure 5 The main function of the screw assembly is to adjust the length of the screw assembly by rotating the inner screw 10, thereby adjusting the projectile angle of the projectile device.

[0031] Press each component Figure 1 As shown in the relationship connection, after the load-bearing vertebral body assembly is assembled to the base assembly, two baffles 4 are tightened on both sides of the load-bearing shaft 20 to prevent the load-bearing vertebral body assembly from moving left and right. The front shaft 25 passes through the shaft support 15 to connect the screw assembly and the base assembly, and is screwed with two nuts 16. The connecting rod 12 passes through the holes of the convex connector 8 and the concave connector 7 to connect the load-bearing vertebral body assembly and the screw assembly.

[0032] The working process of the utility model is as follows:

[0033] Place the projectile device horizontally on the ground, fix the projectile device with four ground nails 18, rotate the inner screw 10 to adjust the projectile angle, place the assembled test projectile on the load-bearing cone assembly, place the wire of the electric ignition head in the wiring groove of the load-bearing cone 5 to prevent it from being pressed, use a strap to tie the test projectile at the notch of the semicircular support 6, and connect the detonator to prepare for detonation.

[0034] When conducting a nearly 90-degree projectile angle test, the screw assembly is passed through the rear shaft 22, and the length of the screw assembly is adjusted so that the projectile angle meets the test requirements, and other assembly relationships remain unchanged.

[0035] After the test is completed, the connecting rod 12 is pulled out, the load-bearing cone assembly is first laid down horizontally, and then the screw assembly is laid down horizontally to complete the storage. Figure 6 shown.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
