Description

Technical Field

[0001] This utility model relates to the field of artillery technology, and in particular to a barrel leveling indicator mechanism installed on a breech mount. Background Technology

[0002] The gun barrel can move back and forth within a cradle, which, with its trunnions as axes, can tilt the barrel. The breech mount moves on a track on the ground, the track direction being consistent with the barrel's axial direction. When the barrel is pushed horizontally backward from the cradle, a level must be used to ensure the gun is level. Due to ground slope and other factors, the track's horizontal state is at an angle to the barrel's vertical direction. Repeated adjustments to the trunnion height and the cradle's tilt angle are necessary to ensure the barrel's axis is parallel to the track's horizontal plane before the barrel can be pulled out of the cradle via the breech mount. Therefore, a barrel leveling indicator mechanism is needed to indicate the barrel's horizontal state. Utility Model Content

[0003] The purpose of this invention is to provide a barrel leveling indicator mechanism installed on the breech mount, which solves the problem that current artillery requires repeated adjustment of the height of the cradle trunnion and the pitch angle of the cradle when the barrel is pushed out of the cradle to make the barrel axis parallel to the horizontal plane of the track before the barrel can be pulled out of the cradle through the breech mount.

[0027] Example

[0028] A barrel leveling indicator mechanism mounted on a breech mount, such as Figures 1 to 7As shown, the system includes a base 100, a slide 200, and an adjustment mechanism 400. The base 100 includes a vertically connected fixed base plate 101 and a base upright plate 102. A groove is provided in the middle of the base upright plate 102, and the slide 200 is slidably connected in the groove. The slide 200 includes a horizontal plate 201, a connecting part 202, and a slide base 300. The horizontal plate 201 is fixedly connected above the connecting part 202. The slide base 300 includes a friction part 301 and a connecting plate 302. The connecting plate 302 is threadedly connected to the connecting part 202 on both sides of the base upright plate 102. The structure 400 includes an adjusting seat 401, a laser generator 403, a cover plate 404, and a clamping screw 405. One end of the adjusting seat 401 is axially connected to one end of the horizontal plate 201, and the other end of the adjusting seat 401 is connected to the other end of the horizontal plate 201 by the clamping screw 405. A spring 406 is inserted through the clamping screw 405 between the adjusting seat 401 and the horizontal plate 201. A laser generator base 402 for placing the laser generator 403 is provided on the adjusting seat 401, and a cover plate 404 connected to the adjusting seat 401 is provided above the laser generator 403.

[0029] Specifically, in this embodiment, the gun barrel leveling indicator mechanism is installed on the breech mount. It indicates the horizontal state of the gun barrel 900 when it is pushed out of the cradle, facilitating the smooth extraction of the gun barrel 900 from the cradle 700 via the breech mount. Specifically, the fixed base plate 101 of the base 100 is connected to the base of the breech mount for leveling the gun barrel 900. A base upright plate 102 with a central groove is vertically connected above the fixed base plate 101, allowing the slide block 200 to slide vertically within the groove. The connecting part 202 below the slide block 200 is fixedly connected to the slide block base 300 on both sides of the base upright plate 102, thus fixing the slide block 200. A horizontal plate 201 above the slide block 200 connects to the adjusting seat 401 of the adjusting mechanism 400. One end of the adjusting seat 401 is connected to the water... The flat plate 201 is rotatable via a shaft connection, and the other end is fixed above the adjustment base 401 by a clamping screw 405. A laser generator 403 is mounted on the top of the adjustment base 401. A laser can be emitted by a button switch behind the laser generator 403, and the position of the laser generator 403 is fixed by two cover plates 404. Because a spring 406 passes through the clamping screw 405, the pitch angle of the adjustment base 401 relative to the horizontal plate 201 can be adjusted by rotating the clamping screw 405, so that the laser beam of the laser generator 403 is parallel to the base.

[0030] Preferably, the leveling indicator mechanism further includes a front calibration plate 500 and a rear calibration plate 600. The front calibration plate 500 is magnetically attached to the end of the gun barrel furthest from the leveling indicator mechanism, and the rear calibration plate 600 is magnetically attached to the end of the gun barrel closest to the leveling indicator mechanism. Both the front calibration plate 500 and the rear calibration plate 600 are transparent, and both have ring-shaped and cross-shaped calibration lines.

[0031] Specifically, the front calibration plate 500 and the rear calibration plate 600 are magnetically attached to the front and rear ends of the gun barrel, respectively. The front calibration plate 500 and the rear calibration plate 600 are identical and are made of transparent acrylic sheets. Annular and cross-shaped calibration lines are set on the surface of the front calibration plate 500 and the rear calibration plate 600 to assist in the position of the laser beam.

[0032] Preferably, a positioning hole 104 is provided on the side of the fixed base plate 101 near the gun barrel 900. The front end of the fixed base plate 101 is fixed to the breech frame by screws through the positioning hole 104. A delta wing reinforcing plate 103 is provided on the other side of the fixed base plate 101 to increase the stability of the base plate 102.

[0033] Preferably, the bottom of the fixed base plate 101 is provided with four fixing grooves, and magnets 105 are glued inside the fixing grooves. The fixed base plate 101 can be attracted and connected to the base plate on the breech frame by means of the magnets 105.

[0034] Preferably, the horizontal plate 201 has a shaft hole at one end near the gun barrel 900, and the adjusting seat 401 also has a shaft hole at one end, so that the adjusting seat 401 and one end of the horizontal plate 201 are connected by the shaft hole. The other end of the horizontal plate 201 has a threaded hole, and the other end of the adjusting seat 401 also has a threaded hole, so that the clamping screw 405 is inserted into the threaded hole to connect the horizontal plate 201 and the adjusting seat 401.

[0035] Preferably, the cover plate 404 and the adjusting seat 401 are fixedly connected by screws. Specifically, the cover plate 404 is inverted U-shaped, and the brackets at both ends are provided with threaded holes. The laser generator base 402 of the adjusting seat 401 is also provided with threaded holes on both sides. Thus, the cover plate 404 can be fixed above the laser generator base 402 by screws to fix the position of the laser generator 403.

[0036] Preferably, friction parts 301 are located at both ends of the connecting plate 302. Friction plates 303 are provided on the side of the friction parts 301 near the base plate 102, and support cylinders 304 are provided on the other side of the friction parts 303. Support springs 305 are installed inside the support cylinders 304, and the openings of the support cylinders 304 are closed by screw caps 306. The connecting plate 302 is located in the groove of the base plate 102, and the friction parts 301 at both ends are in contact with the frame of the base plate 102. Friction plates 303 are provided between the friction parts 301 and the base plate 102 to increase friction. Support springs 305 are installed inside the support cylinders 304 provided on the other side of the friction parts 301 and are closed by screw caps 306. The pressure of the support springs 305 can be adjusted by rotating the screw caps 306, thereby adjusting the friction between the friction parts 301 and the base plate 102, and playing a role in friction braking.

[0037] In use, first install the leveling indicator mechanism on the breech mount base, and then attach the front alignment plate 500 and the rear alignment plate 600 to the front and rear end faces of the barrel 900 respectively. With the barrel roughly horizontal, adjust the height of the slide block 200 by observing the laser beam's position on the front and rear alignment plates 500, ensuring the laser spot on the alignment plates is roughly at the target center. Then, adjust the elevation angle of the cradle 700 and the height of the slide block 200 to ensure both the laser spots on the front alignment plate 500 and the rear alignment plate 600 are at the target center, thus aligning the barrel 900 angle with the guide rail angle. The method for adjusting the leveling indicator mechanism is as follows: place the fixed base plate 101 of the leveling indicator mechanism on the calibrated horizontal surface, place the level instrument on the two cover plates 404 of the laser generator 403, adjust the clamping screws 405 so that the level bubble of the level instrument on the cover plate 404 is centered, then the adjustment base 401 is adjusted and the laser generator 403 is parallel to the fixed base plate 101.

[0038] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
