Description

Technical Field

[0001] This utility model relates to the field of small-caliber artillery barrel firing tests, specifically to a protective device for small-caliber artillery barrel firing tests. Background Technology

[0002] As an important weapon for terminal defense, small-caliber artillery is subject to increasingly higher requirements for its performance indicators. Therefore, it is necessary to conduct various artillery firing tests to verify the research results.

[0003] For newly developed small-caliber artillery, issues such as delayed ignition and failure of lightweight structures have arisen during barrel firing tests. These issues can lead to delayed ignition and casing explosions during firing, causing small-caliber artillery components to shatter into fragments, resulting in damage to testing facilities and equipment, and personnel casualties. Currently, to address these safety concerns, blast walls and doors are installed around the testing site for horizontal protection. However, there is no overhead protection. If delayed ignition or lightweight structure failure occurs during testing, the propellant cartridge may explode within the ejection tube, posing a risk of explosives flying from the top and injuring personnel and damaging equipment. Therefore, an economical, reasonable, and portable top protection measure is urgently needed. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a protective device for small-caliber artillery barrel firing tests. It involves placing the small-caliber artillery inside a support frame and covering its top, left, right, and rear sides with a protective plate. During the firing test, if the ammunition explodes due to delayed ignition or failure of the lightweight structure, causing fragments to fly from the top, the device protects the artillery and prevents injury to people or equipment.

[0005] The technical solution of this utility model is as follows: a protective device for firing tests of small-caliber artillery barrels, including a bracket, the bracket having space in the middle for mounting small-caliber artillery, left, right, top and rear protective plates fixedly installed on the left, right, top and rear sides of the bracket, a passage for small-caliber artillery to pass through on the front side, and multiple casters provided at the bottom of the bracket.

[0006] Preferably, the upper protective plate is welded and fixedly connected to the bracket, the left and right protective plates are respectively hinged to the upper protective plate, and the rear protective plate is welded and fixed to the rear of the bracket.

[0007] Preferably, the lower ends of the left and right protective plates are magnetic, for magnetically fixing them to the lower crossbeam of the bracket.

[0008] Preferably, the left and right protective plates are each provided with a first handle, and the rear protective plate is provided with a second handle.

[0009] Preferably, the support includes four upper crossbeams, four columns, and three lower crossbeams. The four upper crossbeams are connected to form a quadrilateral. The upper ends of the four columns are welded to the four corners of the quadrilateral formed by the upper crossbeams, and the lower ends are connected to the three lower crossbeams, leaving a passage for small-caliber artillery to pass through. Each of the upper and lower crossbeams is provided with a diagonal support beam between it and the connected column.

[0010] Preferably, a first reinforcing beam is provided between two adjacent upper crossbeams, and a second reinforcing beam is provided between two adjacent lower crossbeams.

[0011] The advantages of this utility model are as follows: This utility model is used for safety protection during firing tests of various types of small-caliber artillery barrels, such as 23mm, 25mm, and 30mm calibers. During the firing test of small-caliber artillery barrels, if the ammunition is delayed or the lightweight structure fails, resulting in an explosion and causing parts to fly, this utility model can cover the small-caliber artillery barrel, avoiding safety problems such as equipment damage or personnel injury caused by flying parts. Furthermore, if ammunition needs to be replenished or temporary maintenance is required during firing, the left and right protective plates can be lifted to load ammunition or perform maintenance.

[0013] Figure 2 The second structural diagram of this utility model. Detailed Implementation

[0014] See Figures 1 to 2A protective device for firing tests of small-caliber artillery barrels includes a support frame 7. The support frame 7 has a clearance space 1 in the middle for mounting the small-caliber artillery. Left, right, upper, and rear protective plates are fixedly installed on the left, right, upper, and rear sides of the support frame 7, respectively. A passage for the small-caliber artillery to pass through is provided on the front side. Multiple casters 2 are provided below the support frame 7; in this embodiment, three casters are provided on each of the left and right sides. The upper protective plate 3 is welded and fixedly connected to the support frame 7. The left protective plate 4 and right protective plate 5 are hinged to the upper protective plate 3, respectively. The rear protective plate 6 is welded and fixed to the rear of the support frame 7. By connecting the left and right protective plates to the upper protective plate 3 via hinges, it is possible to lift the left and right protective plates during firing tests to reload ammunition or perform temporary maintenance. The lower ends of the left protective plate 4 and right protective plate 5 are magnetic, used for magnetic fixation to the lower crossbeam 73 of the support frame 7. The left protective plate 4 and right protective plate 5 are each equipped with a first handle 8 for lifting the left and right protective plates, respectively. The rear protective plate 6 is equipped with a second handle 61 for moving the device to a designated position. The support 7 includes four upper crossbeams 71, four columns 72, and three lower crossbeams 73. The four upper crossbeams 71 are connected to form a quadrilateral. The upper ends of the four columns 72 are welded to the four corners of the quadrilateral formed by the upper crossbeams 71, and the lower ends are connected to the three lower crossbeams 73, leaving a passage for small-caliber artillery to pass through. Each upper and lower crossbeam is provided with a diagonal support beam 74 between it and the connected column 72. A first reinforcing beam is provided between two adjacent upper crossbeams 71, and a second reinforcing beam 75 is provided between two adjacent lower crossbeams 73. By establishing the bracket and setting the inclined support beam 74, the first reinforcing beam and the second reinforcing beam 75, the strength of this device is greatly enhanced. This ensures that in the event of a delayed ignition of ammunition or failure of the lightweight structure during the firing test of a small-caliber artillery barrel, which leads to an explosion, this device can block all the fragments after the explosion, preventing the fragments from flying and injuring people.

[0015] The method of using this utility model is as follows: When a small-caliber cannon needs to undergo a barrel firing test, the utility model is manually pushed to the designated position, and then the small-caliber cannon is installed and fixed in the frame of this utility model, so that the protective plate covers the small-caliber cannon. Then the barrel firing test can be carried out. During the entire test, if it is necessary to temporarily repair or reload the small-caliber cannon, the handles on the left and right protective plates can be manually lifted to perform temporary repairs or reloading. During the test, if the small-caliber cannon explodes due to delayed ammunition ignition or failure of the lightweight structure, the top and surrounding protective plates can prevent the flying fragments of the exploded parts from damaging the equipment or injuring the test personnel, thereby improving the safety of the test.

[0016] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications made to the present utility model by those skilled in the art without departing from the spirit of the present utility model shall fall within the protection scope of the present utility model.
