Description

Technical Field

[0001] This utility model relates to the field of cannon barrel technology, specifically a device for adjusting the firing angle of a cannon barrel. Background Technology

[0002] Due to limitations in technology, the angle adjustment for traditional artillery training and firing has long relied on the gunner's experience and visual estimation. In complex battlefield environments or high-intensity training scenarios, this method is prone to deviations in angle setting due to human judgment errors, environmental interference (such as insufficient light or terrain obstruction), and other factors, which can lead to the risk of accidental firing. To avoid the above problems, a gun barrel support has been introduced.

[0003] Existing gun barrel supports have a relatively complex overall structure, are difficult to adjust, and lack flexibility. For example, application number CN202210974129.7 describes a gun barrel angle adjustment support for fire-resistant artillery. The support uses a combination of a rotating block, a support block, a support rod, a spring, and a plug to adjust the tilt angle of the support platform. However, the device has the following drawbacks: the complex mechanical transmission structure makes the operation steps cumbersome, which not only increases the training cost and operation difficulty for gunners, but also makes it difficult to respond quickly in emergency combat scenarios, thus limiting the deployment mobility and tactical flexibility of the artillery.

[0037] The following is a detailed description of this novel experimental device with reference to the accompanying drawings:

[0038] Figure 1-5 This invention discloses a device for adjusting the firing angle of a cannon barrel, comprising: a cannon barrel 1, and further comprising:

[0039] The movable base 2 has an adjustment component 3 slidably disposed in its groove 21, and the adjustment component 3 is hinged to the front side of the barrel 1.

[0040] The unloading component 4 is fixedly installed on the rear side of the movable base 2, and the top of the unloading component 4 is hinged to the tail end of the barrel 1.

[0041] Working principle:

[0042] Since the adjustment component 3 is hinged to the front side of the barrel 1, when the adjustment component 3 slides back and forth in the groove 21 of the movable base 2, it will cause the front end of the barrel 1 to swing up and down, thereby changing the angle between the barrel 1 and the horizontal plane and realizing the adjustment of the firing angle.

[0043] When the cannon barrel 1 finishes firing, it will generate a reverse recoil force, and the entire cannon barrel 1 will move backward. At this time, the force of the backward movement is transmitted to the force relief component 4. The force relief component 4 absorbs and disperses the recoil force through its own elastic deformation, reducing the impact on the moving base 2 and the overall structure, and improving the stability of the device.

[0044] This device allows for continuous or stepped adjustment of the firing angle by adjusting component 3, adapting to different ranges and trajectories. Combined with the force-relief component 4, it effectively buffers recoil, reducing device displacement or vibration and improving structural safety. Furthermore, the movable base 2 facilitates rapid deployment and adjustment of firing posture in different terrains. The overall structure is simple, occupies little space, and is highly mobile.

[0045] As described above, grooves 22 are symmetrically arranged within the groove 21;

[0046] The structure of the adjustment component 3 includes:

[0047] The threaded rod 31 is rotatably disposed in the groove 21, and the tail end of the threaded rod 31 is provided with a rotating handle 32;

[0048] The movable block 33 has a threaded hole 34 through it, and the size of the threaded hole 34 is adapted to the threaded rod 31 to achieve threaded connection. The movable block 33 has protruding sliders 35 symmetrically arranged on both sides, and the protruding sliders 35 are adapted to the slide groove 22 to achieve sliding connection.

[0049] The connecting rod 36 is hinged at one end to the moving block 33 and at the other end to the barrel 1.

[0050] Working principle:

[0051] The operator rotates the handle 32 to rotate the threaded rod 31. Since the threaded rod 31 engages with the threaded hole 34 of the moving block 33, the moving block 33 slides back and forth along the axis of the threaded rod 31 (in actual use, the moving block 33 moves forward when rotating in the forward direction and backward when rotating in the reverse direction, depending on the direction of the thread). The protruding sliders 35 on both sides of the moving block 33 engage with the sliding grooves 22 in the groove 21, restricting the moving block 33 to move only in a straight line along the direction of the sliding grooves 22, thus preventing rotation.

[0052] At this time, when the moving block 33 slides back and forth, it pushes the front end of the cannon barrel 1 to swing up and down through the connecting rod 36, thereby changing the angle between the cannon barrel 1 and the horizontal plane. When the moving block 33 moves forward, the connecting rod 36 lifts the front end of the cannon barrel 1 to reduce the firing angle, and vice versa to increase the firing angle.

[0053] Among them, ① when the moving block 33 is at the end of the groove 21B, the entire barrel 1 is placed horizontally.

[0054] ② Because the vibration during launch may cause the adjustment component 3 to slide and change the preset angle, in order to avoid this problem, this device uses the self-locking property of the threaded rod 31 to prevent the moving block 33 from sliding due to recoil during launch.

[0055] ③ Because the connecting rod 36 needs to bear a large load, high-strength pipes (such as alloy steel) can be selected to improve the bending strength in order to avoid breakage.

[0056] In the above scheme, a plurality of balls 37 are evenly embedded in the bottom of the protruding slider 35, and the balls 37 are rolled in connection with the groove 22.

[0057] Working principle:

[0058] When the operator turns the handle 32 to drive the threaded rod 31 to rotate, the moving block 33 rolls forward / backward in the slide groove 22 through the ball 37, which drives the connecting rod 36 to push and pull the front end of the cannon barrel 1 to achieve the adjustment of the firing angle;

[0059] At this time, the balls 37 are evenly distributed at the bottom of the protruding slider 35, forming rolling support points, making the moving block 33 move more smoothly, turning the original hard sliding friction into rolling friction, reducing the torque required to turn the handle 32, making manual operation easier, and further extending the service life of the device.

[0060] In actual use, the ball bearing 37 can pass over or roll over sand and dust that accidentally enters the slide groove 22, reducing jamming. At the same time, if necessary, the ball bearing 37 can be embedded in the bottom of the protruding slider 35, so that the ball bearing 37 is restricted to a fixed position when rolling in the slide groove 22, avoiding the ball bearing 37 from falling off due to vibration, external impact or long-term use.

[0061] As described above, the structure of the force-relieving component 4 includes:

[0062] The housing 41 is fixedly installed on the rear side of the movable base 2;

[0063] The slide bar assembly 42 is fixedly installed inside the housing 41 in a linear array;

[0064] The buffer seat 43 has a through hole, and the through hole is adapted to slide the slide rod assembly 42 to achieve a sliding connection.

[0065] Spring assembly I 44 is sleeved on slide rod assembly 42. One end of spring assembly I 44 is fixed to the front end of the inner side of housing 41, and the other end is fixed to the front side of buffer seat 43.

[0066] Spring assembly II 45 is sleeved on slide rod assembly 42. One end of spring assembly II 45 is fixed to the rear end of the inner side of housing 41, and the other end is fixed to the rear side of buffer seat 43.

[0067] The hemispherical base 46 is fixedly installed at the tail end of the cannon barrel 1, and the bottom of the hemispherical base 46 is hinged to the top surface of the buffer seat 43.

[0068] Working principle:

[0069] When the cannon barrel 1 fires, the recoil force generated is transmitted to the buffer seat 43 through the hemispherical base 46 at the rear end, causing the buffer seat 43 to shake inside the housing 41.

[0070] At this moment, spring assembly I44 (the front spring assembly) is stretched, and spring assembly II45 (the rear spring assembly) is compressed. Both absorb kinetic energy simultaneously. Spring assembly I44 stores elastic potential energy through stretching deformation, offsetting part of the recoil force. Spring assembly II45 further absorbs impact energy through compression deformation, forming a double buffering effect.

[0071] After the recoil disappears, the elastic tension of spring group I 44 and the elastic thrust of spring group II 45 work together to push the buffer seat 43 forward along the slide rod group 42 to reset, avoiding the lag or shaking that may occur when a single spring resets.

[0072] In actual operation or transportation, the barrel 1 moves forward due to external force (such as transportation bumps), and the buffer seat 43 slides forward along the slide rod group 42. At this time, the spring group I 44 is compressed and the spring group II 45 is stretched. The bidirectional springs work together again to suppress shaking.

[0073] The unloading component 4 achieves dynamic balance of the impact load throughout its entire stroke through the coordinated tension and compression of the front and rear sets of springs. Compared with the unidirectional spring structure, it can absorb the impact force more efficiently.

[0074] As described above, the bottom of the movable base 2 is provided with multiple sets of omnidirectional wheels 5.

[0075] Working principle:

[0076] Due to the free rotation characteristics of the casters 5, the mobile base 2 can turn more flexibly, and the multiple casters 5 distribute the weight of the equipment. At the same time, the self-locking of the casters 5 can also make the device stable during use.

[0077] As described above, the front end of the mobile base 2 is provided with a counterweight 6.

[0078] Working principle:

[0079] Because the center of gravity of the device may shift after the angle of the barrel 1 is adjusted, a counterweight 6 is added to prevent it from tipping over.

[0080] By adding weight to the front end of the mobile base 2 and setting a counterweight 6, the weight of the front and rear ends is balanced, preventing the equipment from tipping over when starting, braking or changing the load (such as when the cannon 1 is firing or when the adjustment angle is too large), and avoiding the mobile base 2 from tilting backward or leaning.

[0081] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
