DETAILED DESCRIPTION

[0033] The present invention will be described in detail below with reference to the accompanying drawings by means of exemplary embodiments of the present invention. It should be noted that the following detailed description of the present invention is only for the purpose of illustration and is not intended to limit the present invention.

[0034] The utility model provides an elevation positioning device for artillery shell loading, which is used to assist in adjusting the elevation angle of the artillery when replenishing artillery shells. The device can position the artillery when the elevation angle is adjusted, so that only one operator can complete the artillery shell loading.

[0035] Overall reference Figures 1 to 4The elevation positioning device for artillery shell loading provided by the present invention is used to be installed between the low-angle limit surface 10 and the low-angle limiter 11 of the artillery 9 to position the artillery when the artillery adjusts the elevation angle during the artillery shell loading operation.

[0036] The elevation positioning device 100 for artillery shell loading, as an exemplary embodiment of the present invention, includes a support member 1, a first connecting rod 2, a positioning bracket 3, a hinge shaft 4, a positioning seat 5, a second connecting rod 6, and a positioning tube 7. To reduce the weight of the device, facilitate operation, and ensure sufficient strength, the support member 1, the first connecting rod 2, the positioning bracket 3, the hinge shaft 4, the positioning seat 5, the second connecting rod 6, and the positioning tube 7 are made of aluminum alloy.

[0037] Figure 5 、 Figure 6 and Figure 7 The support member 1, the first connecting rod 2 and the positioning bracket 3 are shown respectively. The support member 1 is used to cooperate with the low-angle limit surface 10 of the artillery. One end of the first connecting rod 2 is connected to the support member 1, and the other end is connected to the positioning bracket 3. In order to facilitate contact and cooperation with the low-angle limit surface and reduce the direction requirements during use, in some embodiments, the support member 1 is spherical and is provided with a spherical surface 101 for cooperating with the low-angle limit surface 10 of the artillery, which is used to cooperate with the low-angle limit surface 10 to complete positioning. In order to reduce the weight of the device, the first connecting rod 2 is preferably a tubular structure, and the two ends are welded to the support member 1 and the positioning bracket 3 respectively. One end of the positioning bracket 3 can be cylindrical, and the hole in the middle can be used as an axial hole 301. The other end is a rod protruding radially outward from the cylinder. The rod can be used as a positioning portion 302. The axial hole 301 and the positioning portion 301 will be described in detail below.

[0038] Figure 8 The hinge shaft 4 is shown, and the positioning bracket 3 is sleeved on the hinge shaft 4. Specifically, the hinge shaft 4 passes through the axial hole 301 of the hinge shaft 4. To facilitate the installation and positioning of the hinge shaft 4, the pitch positioning device 100 can also include a retaining ring 8, which can be made of a standard stainless steel material. The retaining ring can be clamped onto the hinge shaft 4 to achieve axial positioning. Specifically, one end of the hinge shaft 4 is provided with a radially outwardly protruding flange 401, and the other end is provided with a groove 402 for receiving the retaining ring 8.

[0039] Figure 9A positioning seat 5 is shown, which is used to install the hinge shaft 4 and cooperate with the positioning support 3 to complete the positioning function. In a specific embodiment of the present utility model, the positioning seat 5 includes a base plate 501 and two lugs 502 extending vertically from the base plate 501, the two lugs 502 are arranged in parallel, the hinge shaft 4 is installed through the lugs 502, and the positioning support 3 is located between the two lugs 502. The gap between the lugs 502 and the hole axis of the hinge shaft 4 is very small, and there is a certain friction force, which ensures that the hinge shaft 4 will not rotate on its own or get stuck, and can be rotated by the operator's bare hands. The positioning support 3 can rotate relative to the positioning seat 5 around the hinge shaft 4 so that the positioning support 3 can be folded and unfolded. Compared with the fully unfolded positioning support, when the positioning support is folded, the positioning support 3 is closer to the positioning cylinder 7, so that the device occupies less space. When the device needs to be used, the positioning bracket 3 can be fully unfolded, that is, unfolded to a position where it is tightly attached to and blocked by the positioning seat 5, so that the device is in an unfolded state, and then the unfolded device is installed on the artillery; after the ammunition is loaded and the device is used, the positioning bracket 3 can be rotated in the opposite direction and folded, so that the device is in a folded state, which is convenient for storage and transportation of the device.

[0040] A stopper 503 is provided on the positioning seat 5, and the stopper 503 can be an integral part of the base plate 501 of the positioning seat 5. The stopper 503 is used to act on the positioning portion 302 of the positioning support 3, specifically to block the positioning portion 302 when the positioning support 3 is unfolded to a preset position to limit the movement of the positioning support 3. The preset position refers to a suitable position for loading artillery shells. That is to say, when the device is installed on the artillery and the positioning support 3 moves to a position where it engages with the stopper 503, the artillery is positioned at the correct position for loading artillery shells by adjusting the elevation angle of the artillery until the low-angle limit surface 10 of the artillery is pressed against the support 1.

[0041] Figure 10 and Figure 11 The second connecting rod 6 and the positioning cylinder 7 are shown separately. The positioning cylinder 7 is used to be coaxially sleeved on the low-angle limiter 11 of the artillery. One end of the second connecting rod 6 is connected to the positioning cylinder 7, and the other end is connected to the positioning seat 5. Optionally, the end of the second connecting rod 6 connected to the positioning cylinder 7 is processed with a bevel 601 for fitting and welding with the end face of the positioning cylinder 7. The inclination angle of the bevel 601 can be 12°. It should be understood that those skilled in the art can select the appropriate bevel angle and the installation angle between the various components according to the application scenario of the artillery to achieve positioning of the artillery elevation angle.

[0042] The working process of the pitch positioning device for loading artillery shells of the present invention is as follows: the operator first unfolds the pitch positioning device 100, rotates the positioning support 3 around the hinge shaft 4 until it is in close contact with the positioning seat 5, then puts the positioning tube 7 of the pitch positioning device 100 on the low-angle limiter 11, and then operates the artillery 9 to move to the low-angle position until the support member 1 and the low-angle limit surface 10 are pressed tightly, at which point it is indicated that the pitch positioning device 100 has positioned the accurate position for loading artillery shells. After completing the shell loading, operate the artillery to pitch to a high angle until the support member 1 and the low-angle limit surface 10 are disengaged, then remove the pitch positioning device 100, hold the first connecting rod 2 and the second connecting rod 6 of the pitch positioning device 100, rotate them around the hinge shaft 4, and fold the pitch positioning device 100 away.

[0043] As described above, the present invention includes a support member that cooperates with the low-angle limiting surface of the artillery and a positioning cylinder connected to the low-angle limiter of the artillery. A positioning bracket and a positioning seat are provided between the support member and the positioning cylinder. The positioning bracket connected to the support member can be rotated relative to the positioning seat connected to the positioning cylinder to be retracted and deployed. When using the pitch positioning device to load ammunition, the positioning bracket can be deployed and limited by the stop portion on the positioning seat. The ammunition loading operation can be carried out by rotating the artillery to a negative angle and pressing the support member. Therefore, the pitch positioning device of the present invention allows only one operator to complete the artillery pitch positioning operation required for artillery shell loading, reducing the number of personnel, simplifying the operation, and improving the efficiency of shell loading.

[0044] Finally, it should be noted that the features mentioned and / or illustrated in the above description of the exemplary embodiments of the present invention may be combined in the same or similar manner into one or more other embodiments, and may be combined with or replace the features of other embodiments. The technical solutions obtained by such combination or replacement shall also be deemed to be included in the scope of protection of the present invention.
