Description

The invention relates to transport containers of self-propelled launchers with opening flaps for storing and transporting missiles.

A known container of a self-propelled launcher Point (1) and a self-propelled launcher "Oka" (2) mounted on a wheeled self-propelled chassis containing a frame, a shell having opening ceiling flaps (hatches), while the shell of the container is made of steel sheet, and the mechanism The sash opening is lever.

The disadvantage of this design is the lack of the possibility of temperature control of the space near the TPN, the complexity of the design of the mechanisms of movement of the valves, insufficient strength (rigidity) of the structure.

Known container self-propelled launcher Iskander-E (3) mounted on a wheeled self-propelled chassis containing a frame, a shell having openable shutters, the mechanism for opening the shutters is rocker, while the shell of the container is made of steel sheet.

The disadvantage of this design is the lack of the possibility of temperature control of the space near the TPS, the complexity of the design of the mechanisms of movement of the valves, the insufficient strength (rigidity) of the structure, the lack of reliability of the drive, the time it takes to move the valves, the complexity of the trajectory of movement of the valves.

The technical result of the invention is to reduce the time of movement of the valves, ensuring the tightness of the internal space, increasing the reliability of the device for opening the valves, ensuring thermostating of the space inside the container.

This is achieved by the fact that the container with opening sashes contains a frame with a shell fixed on it, sashes placed in the upper part of the container, installed with the possibility of movement, the mechanism for moving the sashes. The frame contains connected frame structures, the shell is made of thermally insulating material and is mounted on the frame. Each leaf is fixed to a fixed frame with brackets. The contact surfaces of the flaps are equipped with labyrinth seals. The fixed frame contains arcuate guides connected to the wings. The mechanism for moving the leaves is a pin, while the pin sector is fixed to at least one arcuate guide frame of the leaf. The trajectory of the movement of the valves under the influence of the mechanism of movement of the valves is an arc of a circle whose radius coincides with the radius of the guide wings and the guides of the fixed frame. In the open state, the lower edge of the sash abuts against the damper device of the container, and in the closed state the sash is fixed by a stopper. The container is additionally equipped with a system for maintaining the temperature regime in the internal volume.

Frame panels of the frame can be made of tubular elements. Seals of the wings can be made of rubber. The mechanism for moving the leaves can be driven by a mechanical drive.

As a system for maintaining the temperature regime in the internal volume of the container, a forced air boost system with the necessary characteristics was used, containing a fan, air ducts, heaters, coolers (refrigerators), temperature control sensors, and a control unit whose inputs are connected to the sensors and the outputs to devices turning on the heater, refrigerator and fan.

Reducing the time of movement of the valves is achieved by the simplicity of the trajectory of movement of the driven link of the actuator.

The necessary tightness of the internal space is provided by a special labyrinth design of the contacting surfaces of the closed wings. The necessary thermal insulation is ensured by the container shell made of heat-insulating material, for example, from special multilayer panels (“sandwich panels”) made of a material with a low heat transfer coefficient.

An increase in the reliability level of the leaf opening device is achieved by the simplicity of the design of the supporting elements of the leaf movement mechanism.

In FIG. 1 shows the stationary frame of the container (rear view, from the end) with the left wing in the closed position, containing elements of the mechanism for moving the wings.

In FIG. 2 shows the frame of the container (side view, in length) with a mechanism for moving the leaves.

The transport container comprises a frame 1 and a casing 2 fixed to the frame 1. In the upper part of the container, movable leaves 3 are placed. The container contains a mechanism for moving the leaves 3, which includes a sprocket sector 4 mounted on at least one arcuate guide 5 of the casement frame 3, leading asterisk 6; gearbox 7 and motor 8. The container is additionally equipped with a damper device. Elements of the pinwheel sector 4 (pin) are cylindrical. The fixed frame 1 of the container contains arcuate guides 9, to which the sashes 3 are attached. Moreover, the radii of the arcuate guides of the frame 9 and the sashes 5 coincide. The fastening of the leaves 3 can be carried out through the brackets 10 of the leaves 3, containing bodies of sliding, rolling or rotation, or are made as a slide. The trajectory of movement of the sash 3 under the influence of the mechanism of movement of the sash 3 is an arc of a circle,

- 1 009273 while in the open state, the lower edge of the sash 3 abuts against the damper device of the container, and in the closed state, the sash 3 is fixed by a stopper. The locking device can be made hydromechanical. The contact surfaces of the sash 3 have a seal 11 labyrinth design.

Operating principle

In the stowed (transport) position, the sashes 3 of the container are closed and held by the stopper. When the shutters open, the locking device opens. The rotor of the motor 8 is driven, the torque through the gearbox 7 is supplied to the drive sprocket 6, which starts to rotate and moves the spool sector 4 in the arc. The sprocket sector 4 moves the leaf 3 along the guide frame 9 down the circular arc to the stop of the lower edge of the leaf 3 in damper device. The opposite leaf moves similarly and synchronously.

When the direction of rotation of the rotor of the motor is reversed, the mechanism and the movement of the wings are carried out in the same sequence, but in the opposite direction.
