Abstract

FIELD: self-propelled launchers for transportation and launch of missiles from transportation - launching packs with the aid of solid-propellant gas generators.

SUBSTANCE: the launcher is provided at least with two supports made in the form of double-rod hydraulic cylinders of double-sided action. The upper rod of each hydraulic cylinder is linked with a movable frame, and the lower rod - with a hinge-mounted supporting plate and a supports driving mechanism having levers and tie-rods. The levers are hinge-mounted on one side on the body frame, and on the other - on the double-rod hydraulic cylinders of double-sided action. The tie-rods are hinge-mounted on a boom, and on the other - on the mentioned levers.

EFFECT: reduced time of deployment and closure of the self-propelled launcher and considerably reduced loads on the self-propelled launcher at launching.

Description

The invention relates to self-propelled launchers (SPU) for transporting and launching missiles from transport and launch containers (TPK) using powder pressure accumulators.

Famous domestic combat vehicle ZRS "S-300PMU" (Shunkov VN Missile weapons. Mn .: OOO "Potpourri", 2001, 528 p., S. 484-489), made on a wheeled self-propelled chassis with a body frame, lifting mechanism, hydraulic boom, hydraulic cylinders for installing each TPK separately in the starting position.

The disadvantages of this design are:

- the large expenditures of time required when unleashing with the help of a hydraulic drive of each TPK separately to reduce the force effect of the launching rocket on the machine;

- time-consuming deployment and folding of the machine;

- a rather complicated design of the hydraulic drive for untying the TPK.

Known self-propelled launcher "Iskander-E" (Shunkov VN Missile weapons. Mn .: LLC "Potpourri", 2001, 528 p., P.182-192), made on a wheeled self-propelled chassis with a body frame, an arrow , hydraulic drive, mechanism for mounting and lifting the boom.

The disadvantage of this design is that the rocket starts directly from the boom and the force from the rocket is completely transmitted to the SPU.

The technical result of the present invention is to reduce the time for deployment and curtailment of the control system and significantly reduce the load on the control system at startup.

This is achieved by the fact that the SPU is formed on a self-propelled wheeled chassis, contains a body frame fixedly mounted on the chassis, an arrow pivotally mounted on the body frame, a boom lifting mechanism for raising and lowering the boom, and a movable frame with the possibility of longitudinal movement along the boom to a hard stop , TPK, mounted on a frame movable in tool holders, at least three, supports, at least two, made in the form of double-ended double-acting hydraulic cylinders with an upper rod and lower rod with a pivotally mounted support with a slab, a support drive mechanism containing levers of at least four, pivotally mounted on one side on the body frame, and on the other, on two-piece double-acting hydraulic cylinders and traction, at least two, pivotally mounted on one side on the boom, and on the other on leverage.

The reduction of the power effect of the launching rocket on the SPU is achieved by the fact that the supports made in the form of double-acting double-acting hydraulic cylinders with an upper rod and a lower rod with an articulated support plate are installed at launch between a movable frame with a TPK and soil fixed to it, which ensures decoupling the longitudinal direction of the frame is movable with TPK and boom and the transmission of force from the launching rocket through supports directly to the ground.

Reducing the time for deployment and folding of SPU is achieved by the fact that the support drive mechanism transfers the supports from the stowed position to the working position and vice versa simultaneously with the raising or lowering of the boom due to the interaction of the levers mounted pivotally on one side of the body frame and on the other on two-piece double-sided hydraulic cylinders actions, and rods pivotally mounted on one side of the boom, and on the other on the levers.

Figure 1 presents a General view of the SPU in the stowed position;

figure 2 presents a General view of the SPU in the working position;

figure 3, 4 presents the support in the stowed and working positions.

The combat vehicle contains a self-propelled wheeled chassis 1, on which a body frame 2 is fixed, an arrow 3, which is pivotally mounted on a body frame 2, a boom lifting mechanism 4, a movable frame 5, which is placed on the arrow 3 with the possibility of longitudinal movement to a hard stop 6. TPK 7 are fixed on the movable frame 5 in the lodges 8. On the body frame 2 and boom 3 there are supports pivotally connected by levers 13 and rods 14 of the support drive mechanism. The support is made in the form of a two-rod double-acting hydraulic cylinder 9 with an upper rod 10, a lower rod 11 with a pivotally mounted base plate 12.

SPU works as follows.

In the stowed position TPK 7 are fixed on the movable frame 5 in the tool holders 8. The movable frame 5 is fixed on the boom 3, the lifting mechanism of the boom 4 and boom 3 are laid in the stowed position, supports made in the form of a two-pin double-acting hydraulic cylinder 9 with the upper rod 10, lower the rod 11c pivotally mounted base plate 12, raised under the influence of levers 13 and rods 14 of the drive mechanism of the supports.

The boom 3 and the movable frame 5 with the TPK 7 are lifted by the boom lifting mechanism 4. In this case, the rods 14 of the support drive mechanism through the levers 13 translate the supports into working position. At the same time, the frame 5 is unfastened in the longitudinal direction from the boom 3.

At the end of the lift, the boom 3 becomes and is held in a vertical position by the boom lifting mechanism 4, the movable frame 5 with the TPK 7 attached to it is held from moving down by the rigid stop 6 of the boom 3.

Supports under the influence of levers 13 and rods 14 of the support drive mechanism occupy a position coaxial with TPK 7 in a vertical plane.

The upper rod 10 and the lower rod 11 of the double-ended double-acting hydraulic cylinder 9 are simultaneously extended 9. The lower rod 11 abuts the ground through the base plate 12, and the upper rod 10 raises the movable frame 5 with TPK 7 fixed to it.

At the time of start-up, the movable frame 5 with the TPK 7 is untied in the vertical direction with the boom 3 and rests on the ground through the supports. In this case, the force from a vertically launching rocket is transmitted to the ground through the supports, bypassing the body frame 2 SPU.

After starting, the upper rod 10 and lower rod 11 are retracted with the base plate 12 of the double-acting double-acting hydraulic cylinder 9. At the same time, the movable frame 5 with the TPK 7 lowers on the boom 3 to the hard stop 6. After that, the arrow 3, the movable frame 5 with the TPK 7 are lowered in the stowed position by the boom lifting mechanism 4. In this case, the rods 14 of the support drive mechanism by means of levers 13 translate the supports into the stowed position. The frame 5 is fixed in the longitudinal direction on the boom 3 in the stowed position.
