Description

Technical Field

[0001] The utility model belongs to the technical field of weapon technology, in particular to the field of large-caliber cluster bombs; specifically, it is a large-caliber warhead horizontal state test device. Background Art

[0002] During the development of large-caliber warheads, tests are typically conducted with the warhead placed vertically on a test platform for scenarios such as opening the mothership and dispersing the projectile. In these cases, only a test platform of a certain height and the necessary interfaces to secure the warhead are required to meet the test requirements.

[0003] With the development of the times, warheads have a wider range of performance-related units, such as drones and information platforms. Some warheads have different simulation requirements for their posture during operation. Compared to the typical vertical placement, which can only simulate vertical drops or small deflection angles, horizontal placement allows for a wider range of simulation conditions. To address the horizontal operation requirements of certain warheads, a horizontal state test device was designed. Summary of the Invention

[0004] (1) Purpose of the invention

[0005] The utility model aims to provide a horizontal state test device which is simple to operate, convenient to install and suitable for most large-caliber warheads.

[0006] (2) Technical solution

[0007] In order to achieve the above objectives and solve the above technical problems, the technical solutions provided by the present invention are as follows:

[0008] The utility model is mainly composed of a main support frame 1, a connecting bracket 2, and a secondary support frame 3. Figure 1 shown.

[0009] The main support frame 1 serves as the support for the entire test device. It is composed of two steel plates of the same size as the upper plate and the bottom plate. Six square steel pipes are welded between the upper plate and the bottom plate. The bottom plate in contact with the ground has multiple anchor bolt mounting holes. Anchor bolts are installed according to task requirements to increase safety. The main support frame is connected to the connecting bracket through the mounting holes on the upper plate. The main support frame serves as the support for the entire test device. It is composed of two 2000mm×2000mm×20mm steel plates as the upper plate and the bottom plate, and is welded with six 1880mm long square steel pipes. The bottom plate connected to the ground has multiple anchor bolt mounting holes. Anchor bolts are installed according to task requirements to increase safety. The main support frame is connected to the connecting bracket through the mounting holes on the upper plate. Figure 2 .

[0010] The connecting bracket 2 is used to connect the target warhead. The connecting bracket 2 consists of a receiving bracket 4 and a connecting plate 5. The connecting bracket 2 is connected to the main support frame 1 through M36 standard bolts, and the connecting plate 5 is connected to the receiving bracket 4 through M36 bolts. At the same time, the main support frame 1 has a corresponding interface for mounting the connecting plate 5. The connecting plate 5 is provided with an interface adapted to target warheads of different calibers for connecting the warhead. There are two connecting brackets 2, one connected to the main support frame 1 and the other connected to the auxiliary support frame 3. Figure 3 shown.

[0011] The secondary support frame 3, used in conjunction with the main support frame 1, consists of a secondary support frame 6, an adjustment frame 7, linear bearings 8, a jack 9, a support platform 10, and an auxiliary connecting frame 11. After the target warhead is installed in the test apparatus, the secondary support frame 3 becomes a cantilever beam structure; it provides auxiliary support for the target warhead, which is heavy and has relatively uneven ground during field tests. The secondary support frame 6 acts as a support, connecting and securing the adjustment frame 7 to the secondary support frame 6 with M36 bolts. The jack 9 controls the vertical adjustment of the support platform 10 to stabilize the auxiliary connecting frame 11. Four linear bearings 8 ensure continuity during the support platform adjustment process. The auxiliary connecting frame 11 is connected to the connection plate 5 at the corresponding connection interface.

[0012] Furthermore, when the connecting plate 5 is installed flatly at the center of the upper plate of the main support frame 1, the test device can be used for the vertical state action test of the target warhead.

[0013] (3) Effective income

[0014] 1. This test device is simple to operate and install, suitable for most large-caliber warheads, and is also downwardly compatible with warheads of other calibers. It provides modification space for different warhead installation interfaces, which can be met by adding corresponding interfaces to the connecting bracket. It also provides additional space for installing counterweight blocks to ensure safe application in cases with large warhead masses.

[0015] 2. When the target warhead mass is no more than 2T, the main support frame of the utility model can meet the requirements, and the auxiliary support frame can be used in conjunction with it to increase safety when necessary; the main support frame can be used as a test platform for vertical attitude tests without being connected to the connecting bracket.

[0023] The test device of the present invention mainly consists of three parts: a main support frame, a connecting bracket and a secondary support frame. The working mechanism of each part of the device is described in detail below.

[0024] The main support frame 1 is the support of the entire test device. The bottom plate connected to the ground has multiple anchor bolt installation holes. Anchor bolts can be installed when necessary to increase safety. At the same time, there is a reserved space for installing counterweight blocks. Counterweight blocks can be installed when necessary to increase stability. Figure 6 As shown, the assembly status is as follows Figure 4 As shown, when the auxiliary support frame is selected, the connection status is as follows Figure 1 shown.

[0025] First, deploy the main support frame at the target test site. Selectively add anchor bolts or counterweights based on actual usage requirements. Generally, unless under special circumstances, such as when the test target has a large deadweight or its center of gravity is severely eccentric due to its structural characteristics, the weight of the main support frame itself can meet the test usage requirements.

[0026] The second step is to connect the connecting bracket 2 to the main support frame 1 through M36 standard bolts, and connect the connecting plate 5 to the receiving bracket 4 through M36 bolts. At the same time, the main support frame 1 has a corresponding interface for installing the connecting plate 5. The connecting plate 5 can be processed and modified according to the installation interface of the target warhead to adapt to different target warheads. The modification space has been reserved by the design and can meet the modification requirements of the warhead interface of most calibers. When the main support frame 1 is only installed with the connecting plate 5, the test device can be used for the vertical state action test of the target warhead. See the two installation conditions. Figure 5 .

[0027] The third step is to select the auxiliary support frame according to actual usage.

[0028] The secondary support frame 3 is primarily used in conjunction with the main support frame 1 during field tests involving large warhead masses and uneven terrain to enhance stability and safety. The approximate position of the secondary support frame 1 is determined based on the target warhead's dimensions. The secondary support frame 6 serves as a support, and the adjustment frame 7 is connected and secured to the secondary support frame 6 via M36 bolts. A jack 9 controls the vertical adjustment of the support platform 10 to stabilize the auxiliary connecting frame 11. Four linear bearings 8 ensure continuity during support platform adjustments. The auxiliary connecting frame 11 is connected to the support frame 4, and its corresponding connection interface can be connected to the connection plate or machined into a reserved position as needed.

[0029] The above is a further detailed description of the present invention in conjunction with specific embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
