Description

The present invention relates to the field of artillery weapons, and more particularly to breech-loading mortars.

As you know, mortars are muzzle-loading and breech-loading. The advantage of mortar-loading mortars is the convenience of loading, especially large-caliber mortars, the possibility of firing from cover with less chance of hitting the crew members from enemy fire, the possibility of increasing the length of the barrel and the absence of double loading problems.

Known 120-mm muzzle-loading rifled mortar MO-120 RT61 (France), weighing 574 kg ("Foreign military equipment", ser.11, 1979, issue 26, S. 11-13, Internationale Wehrrevue, 1985, v. 18, No. 3, p. 403-404). This mortar has all the disadvantages of muzzle-loading mortars.

There is a 120-mm breech-loading mortar (RF patent No. 2102681 from 07.20.95, F41F 1/06). This mortar contains a barrel with a bolt, a shock absorber, a frame with a breech, a base plate and a machine with guidance mechanisms. The barrel with the help of the basting and the axles of the pins is fixed on the frame and can be rotated on the axes of the pins in a vertical plane and can be fixed in two positions, in combat and for loading. The shutter with the help of an axis parallel to the bore is pivotally mounted on the barrel and, when opened, rotates to the side.

The disadvantages of the state-loading mortar include:

- the presence of a fixed distance between the wheels, that is, the presence of a constant track prevents the possibility of towing it for various vehicles;

- the inability to quickly disassemble into component wearable parts and assemblies;

- there is no possibility of disassembly for transportation in parts;

- when pointing at a target in a vertical plane, the handle of the drive of vertical guidance goes far from the handle of the rotary mechanism.

For the prototype, we adopted a 120-mm breech-loading mortar (RF patent No. 2102681 of 07.20.95, F41F 1/06).

The technical result of the invention is the possibility of towing behind various vehicles, transportation and carrying the breech-loading mortar in disassembled form and the convenience of pointing in the vertical plane.

The technical result is achieved by the fact that in an artillery gun containing a barrel, a frame with a breech, a bolt, a two-leg carriage, having an axis with torsion bars, balancers, a half shaft with hubs and wheels, a carriage with a rotary mechanism and a lifting mechanism moving along the axis of the two-leg carriage, two sliding rods with movable axes located inside them are inserted into the axis of the bifold carriage, while the torsion bars are fixed at one end in the rods and the other end at the movable axes, and the balancers are fixed on the movable axes, and closed in the two-leg carriage. openers are mounted on the sliding rods, while the sliding rods with axles and torsion bars, balancers and coulters are fixed with fingers, and the axle shafts with hubs and wheels are fixed in the balancers with handwheels with clamps, and the lifting mechanism is made screw, telescopic with a movable housing relative to the carriage, connected by a double screw , a running screw with a frame with a breech cross and a fixed uterus connected by a heel to the carriage body.

Figure 1 shows a General view of the mortar in a combat position; figure 2 shows the mortar in the stowed position; figure 3 shows a two-leg carriage; figure 4 shows the axis of the bipod-carriage mortar in the context; figure 5 shows the quick-mount wheel to the balancer; 6 shows a telescopic lifting screw mechanism.

The breech-loading mortar (Fig. 1) contains a barrel 1, a frame with a breech 2, a plate 3, pivotally connected to a biped-carriage 4 by means of a lifting screw guidance mechanism 9 (Fig. 3), placed in the carriage housing 10 together with a horizontal guidance drive 8. The carriage 10 is moved along the axis 20 of the two-leg carriage (Fig. 4) with the help of gear 25 of the horizontal guidance drive, while the axis of the two-leg carriage is protected by covers 15 and the sliding rods 18 and 19 are located in it, fixed in a predetermined position by the fingers 7. On the bars 18 and 19 fingers 6 are fixed the left-hand collar 5 and the right-hand opener 16. Inside the rods 18 and 19 and in the axles 23, the torsions 21 and 22 are fixed, and on the axes with the help of the fingers 24, the balancers 11 and 12 are attached, in which using the flywheels 14 (Fig. 5), locked with clamps 13, wheels 17 with hubs 26 and half shafts 27 are attached. The lifting screw mechanism (Fig. 6) is connected to the barrel, the frame with the breech and the plate by means of a cross 28 mounted on the running screw 29, interacting with the double screw 32, which receives rotational movement through the gear 31 from a handle 36 mounted in a movable relative to the housing and the carriage of the housing 33 with the help of the nut 38, by means of the gear 37, at the same time, the double screw 32 moves the movable housing 33 along the fixed uterus 34 connected via the heel 35 to the housing of the lifting screw guidance mechanism 9 (Fig. 3) located in the housing carriages 10.

The breech-loading mortar works as follows. To transmit torque from the threaded barrel 1 to the ground, it is intended to be seized by the shock absorber body and to transmit torque using the eyes and crosspiece 28 of the lifting mechanism 9 connected to the rods, which eliminates the weakest elements from the torque transmission chain. To further transmit the moment, the lifting and swivel mechanisms are mounted on the carriage 10, which has the ability to move left and right along the axis of the two-leg carriage 4 with the teeth of the rail cut on it. Rotating the handle of the rotary mechanism, the gear interacts with the gear rack of the axis of the two-leg carriage 4 and guides the artillery gun horizontally. When fired, the carriage 10 transfers the force from the torque to the axis of the two-leg carriage 4, the axis of the two-leg carriage 4 to the two sliding rods 18 and 19 with torsion bars 21 and 22 inserted into it, at the ends of which the coulters 5 and 16 are fixed. The two-leg carriage 4 at the same time, it is a wheel drive for a breech-loading mortar, since on the axis of the bogie carriage 4 with inserted sliding rods 18 and 19, with torsion bars 21 and 22 and coulters 5 and 16, balancers 11 and 12 with half shafts 27 and wheels 17 are fixed.

The transfer from traveling to combat is as follows. The stopper is removed, which is marching located on the frame with breech 2. The barrel of the mortar 1 is lifted and the two-leg carriage 4 is rolled out on wheels 17 under the action of gravity to the stop of the coulters 5 and 16 in the ground. Next, the barrel 1 is unlocked for the first loading.

Dismantling the mortar for transportation and carrying parts is carried out as follows. The stopper is removed, which is marching located on the frame with breech 2. The barrel of the mortar 1 is lifted and the two-leg carriage 4 is rolled out on wheels 17 under the action of gravity to the stop of the coulters 5 and 16 in the ground. Next, the barrel 1 is unlocked, as for the first loading and is separated from the frame with the breech and stove connected to the biped-carriage. Further, the frame with the breech and the plate are separated from the biped-carriage and are divided among themselves.

The breech-loading mortar has the ability to be towed behind vehicles with different gauges, transported and transported in parts.

The gauge is changed by moving the rods 18 and 19 inside the axis of the two-leg carriage fixed by the fingers 7. The bars 18 and 19 can be easily removed and inserted into the axis 20 of the two-leg carriage. Wheels 17 with hubs 26 and half shafts 27 can be easily removed and attached to the balancers 11 and 12 with the help of flywheels 14, which are locked by the locks 13. The balancers are attached to the axles 23 with torsion bars 21 and 22 by means of the pins 24 fixed in the rods 18 and 19, on which by means of fingers 6, the openers left 5 and right 16 are fixed.

Mortar guidance on the target is carried out using a horizontal guidance drive 8 and a lifting screw guidance mechanism 9, located in the housing of the carriage 10, with the ability to move along the axis 20 of the two-leg carriage. When aiming at a target in a vertical plane, the handle 36 of the vertical guidance drive 9 as a result of applying a helical telescopic mechanism leaves the handle of the rotary mechanism 8 at a distance two times smaller than in the existing mortar, and this greatly facilitates the work of the gunner.
