Description

Technical Field

[0001] This invention relates to the field of artillery maintenance and support equipment, and in particular to a general-purpose artillery shell unloading and barrel comprehensive testing device. Background Technology

[0002] Currently, separate-loading projectiles remain an important component of weapon ammunition. Due to their advantages of variable propellant charge and portable reloading, they have always been favored and are widely used in weapons and equipment such as tank guns and ground artillery. When special circumstances arise during live-fire exercises, such as equipment malfunctions, sudden changes in weather (rain, snow, hail), or relocation of positions, requiring a halt to firing, the loaded projectiles must be ejected.

[0003] Due to the nature of separate-loading projectiles, the general procedure for unloading them is as follows: after the cartridge case is ejected, the gun barrel is leveled, a simple ejector is screwed onto the front of the barrel lever and inserted into the muzzle. Multiple people work together to impact the projectile's head, causing the projectile's cartridge band to detach from the rifling, ultimately loosening the projectile and ejecting it from the barrel. Because the fuse is not unscrewed during unloading of separate-loading projectiles, the ejector device is designed with a cone-shaped funnel in the middle to avoid direct impact on the fuse. Furthermore, due to the large impact force and the long barrel length, the point of impact cannot be precisely positioned, and the impact force inevitably acts on the fuse during unloading. If the applied instantaneous impact force exceeds the equivalent value of the fuse's safety factor, it may cause changes to the internal mechanical components of the fuse. This can lead to barrel explosion during unloading or premature detonation of the unloaded projectile in the next firing, posing a significant safety hazard to personnel and equipment. Unloading projectiles with the cartridge case in the barrel carries extremely high safety risks. In addition, the ejection of the projectile requires a large continuous thrust or instantaneous impact force. When the handle is subjected to axial thrust, it will bend, making it difficult to maintain a continuous and fixed thrust for ejection.

[0004] Therefore, how to provide a safe and reliable maintenance and support device has become the problem that needs to be solved. Summary of the Invention

[0146] This embodiment presents a general-purpose artillery shell ejection and bore inspection device. By combining different functional modules with a basic module, it achieves the functions of fuse retraction, shell ejection, and bore inspection. The specific working principle is as follows:

[0147] 1. Basic module installation of fuze retraction unit (e.g.) Figure 38 (As shown)

[0148] The basic module, connected to the fuse retraction unit, is inserted into the cannon barrel from the muzzle. The adjustment handwheel of the power unit is turned, which drives the adjustment screw to rotate, causing the adjustment screw sleeve to move forward and the support arm to expand outward until the traveling wheel contacts the barrel. To generate greater friction when the traveling wheel rotates, and to allow the traveling wheel to roll over foreign objects such as copper residue and gunpowder residue on the inner wall of the barrel, the disc spring provides elasticity.

[0149] After the traveling wheels are adjusted to the correct position, click the "Forward" button in the fuze retraction function area of ​​the control panel configuration screen. The signal is transmitted to the PLC via the first LORA-ETH wireless communication module. The PLC's Y3 relay is activated, and the power unit's motor M3 rotates, driving the worm gear to rotate. The rotational power is transmitted to the traveling wheels through the worm wheel, pulley, and synchronous belt, thus causing the entire unit to move forward along the barrel. During this process, the "Forward" button remains selected.

[0150] When the entire assembly advances to the point where the fuze retraction unit is located within the gun barrel and the projectile is positioned, the conical surface of the conical screw contacts the conical surface of the fuze. The conical surface of the fuze forces the conical screw to rotate counterclockwise around the pinion shaft. Under the action of the retraction gear, the pinion drives the rotary table to rotate around the retraction sleeve, and the tension spring is stretched as the rotary table rotates. When the conical surface of the fuze touches the contact of the clamping microswitch K4, the clamping microswitch K4 outputs a stop signal. The PLC inputs a signal to X4, the PLC's Y3 relay disconnects, and the motor M3 stops rotating. Simultaneously, the PLC sends a signal to the configuration screen via the first LORA-ETH wireless communication module, and the "Forward" button on the configuration screen cancels the hold selection mode.

[0151] Select the "Retract Fuze" button in the fuze retraction function area of ​​the control panel's configuration screen. The signal is transmitted to the PLC via the first LORA-ETH wireless communication module. The PLC's Y2 relay is activated, and the motor M2 of the braking unit rotates, driving the brake transmission screw to rotate and causing the brake transmission sleeve to move forward until it touches the contact of the front micro switch K1. The PLC's X1 is activated, the PLC's Y2 relay is deactivated, and the motor M2 stops rotating. During this process, the brake transmission sleeve pushes the first brake block to move outward along the first brake guide channel through the first connecting rod. The friction plate contacts the inner wall of the gun barrel, generating friction and restricting the rotation of the overall detection device inside the gun barrel. Then, the PLC's Y1 is activated for 2 seconds and then deactivated. At this time, the rotating unit's motor M1 rotates for 2 seconds and then stops rotating. During this process, the motor M1 drives the rotating power end to rotate, thereby causing the retraction sleeve to rotate. The rotating unit rotates around the bore axis. The conical surface of the conical screw has helical blades, which prevent the fuse from slipping backward when acting on the conical surface of the fuse. Simultaneously, under the action of the tension spring, the three conical screws have a self-holding characteristic when rotating the fuse, preventing slippage on the fuse's conical surface. The three conical screws act on the fuse, loosening it. After motor M1 stops rotating, PLC's Y2 is activated, and motor M2 of the braking unit rotates in the opposite direction. The brake transmission sleeve moves backward, causing the first brake block to disengage from the bore wall, releasing the brake until it touches the contact of microswitch K2. PLC's Y1 is activated for 12 seconds and then deactivated, causing motor M1 of the rotating unit to rotate, unscrewing the fuse through the three conical screws. Simultaneously, the PLC sends a signal to the configuration screen via the first LORA-ETH wireless communication module, canceling the "Remove Fuze" button on the configuration screen from holding the selected mode.

[0152] Click the "Exit" button in the fuze retraction function area of ​​the configuration screen on the control panel. The signal is transmitted to the PLC through the first LORA-ETH wireless communication module. The Y3 relay of the PLC is turned on, the motor M3 of the power unit reverses, and the overall detection device moves backward and exits the barrel; thus completing the fuze retraction operation.

[0153] 2. Basic module installation of ejection unit (e.g.) Figure 39 (As shown)

[0154] Clicking the "Forward" button in the unloading function area of ​​the control panel configuration screen sends a signal to the PLC via the first LORA-ETH wireless communication module. The PLC's Y3 relay is activated, the power unit starts, and the entire unit moves forward along the barrel. During this process, the "Forward" button remains selected.

[0155] When the entire assembly advances to the projectile position within the barrel of the ejection unit, the inner cone of the ejection unit contacts the conical head of the projectile until the projectile head touches the ejection microswitch K5. At this point, the ejection microswitch K5 outputs a stop signal; the PLC inputs a signal to X4, the PLC's Y3 relay disconnects, and the motor M3 stops rotating; simultaneously, the PLC sends a signal to the configuration screen via the first LORA-ETH wireless communication module, and the "Forward" button on the configuration screen cancels the hold selection mode.

[0156] Clicking the "Retrieve" button in the configuration panel of the control console sends a signal to the PLC via the first LORA-ETH wireless communication module. The PLC's Y2 relay activates, causing the braking unit's motor M2 to rotate, which in turn rotates the braking transmission screw, moving the braking transmission sleeve forward until it touches the contact of the front microswitch K1. This activates the PLC's X1 relay, deactivates the PLC's Y2 relay, and stops the motor M2. The basic module then forms a brake within the barrel. The PLC's Y1 relay deactivates after 10 seconds, resuming rotation. When the motor M1 of the unit rotates, the internal threaded cylinder of the ejection unit rotates, causing the ejection cylinder to move forward along the ejection connecting cylinder, and the ejection cylinder ejects the projectile. After the motor M1 stops rotating, the Y2 of the PLC is turned on, the motor M2 of the braking unit rotates in the opposite direction, the brake transmission sleeve moves backward, and drives the first brake block to disengage from the inner wall of the barrel, releasing the brake until it touches the contact of the micro switch K2. At the same time, the PLC sends a signal to the configuration screen through the first LORA-ETH wireless communication module, and the "ejection" button on the configuration screen cancels the hold point selection mode.

[0157] Click the "Exit" button in the ejection function area of ​​the control panel configuration screen. The signal is transmitted to the PLC through the first LORA-ETH wireless communication module. The PLC's Y3 relay is turned on, the power unit's motor M3 reverses, and the overall detection device moves backward and exits the gun barrel; thus completing the fuse ejection operation.

[0158] 3. Basic module installation of inspection unit (e.g.) Figure 40 (As shown)

[0159] Click the "Forward" button in the barrel inspection function area of ​​the control panel configuration screen. The signal is transmitted to the PLC through the first LORA-ETH wireless communication module. The Y3 relay of the PLC is turned on, the power unit is started, and the whole thing moves forward along the barrel.

[0160] Click the "Turn Left" button in the viewing area of ​​the configuration screen on the control panel. The signal is transmitted to the PLC through the first LORA-ETH wireless communication module. The Y4 relay of the PLC is turned on, and the pan-tilt dome camera's pan-tilt motor M4 drives the dome camera to turn left. The screen on the display terminal turns left to view the surroundings.

[0161] Click the "Turn Right" button in the viewing area of ​​the configuration screen on the control panel. The signal is transmitted to the PLC through the first LORA-ETH wireless communication module. The Y4 relay of the PLC is turned on, and the pan-tilt dome camera's pan-tilt motor M4 drives the dome camera to turn right. The screen on the display terminal turns right and surrounds the camera.

[0162] Click the "Up" button in the borehole viewing function area of ​​the control panel configuration screen. The signal is transmitted to the PLC through the first LORA-ETH wireless communication module. The Y5 relay of the PLC is turned on, and the vertical rotation motor M5 of the pan-tilt dome camera drives the dome camera to rotate vertically. The screen on the display terminal moves towards the borehole axis.

[0163] Click the "down" button in the borehole inspection function area of ​​the control panel configuration screen. The signal is transmitted to the PLC through the first LORA-ETH wireless communication module. The Y5 relay of the PLC is turned on, and the vertical rotation motor M5 of the pan-tilt dome camera drives the dome camera to rotate vertically. The image on the display terminal moves towards the inner wall of the borehole.

[0164] Click the "Exit" button in the barrel inspection function area of ​​the configuration screen on the control panel. The signal is transmitted to the PLC through the first LORA-ETH wireless communication module. The Y3 relay of the PLC is turned on, the motor M3 of the power unit reverses, and the overall detection device moves backward and exits the barrel; thus completing the fuse retraction operation.
