Description

The invention relates to the transport engineering, in particular to the railway transport, and is intended for the transport of long goods having a circular shape and a relatively thin bearing shell.

The purpose of the invention is to increase the 5 operational qualities and harden the structure by eliminating the mutual displacements of the frames while ensuring their horizontal position when the vehicle is moving without load and to the loading point.

FIG. 1 schematically shows a vehicle, a general view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 is a view B in FIG. 3; in fig. 5 is a section BB in FIG. 2

The vehicle contains wheeled carts 1 and 2, rigidly connected respectively to frames 3 and 4. The frames of the carts are interconnected by a longitudinal bar 5. The longitudinal bar 5 is connected to one of the frames of the carts (in this particular case, the frame 3, TV 1, 1) - Nirno by means of its pin 6. The second end of the longitudinal rod is connected to the other frame of the trolley 2 with the help of finger 7. At one end (Fig. 4), the finger is mounted in the lug 8 of the rod 5 and in the lug 9 of the frame 4 with the formation of a hinge. At the other end, the finger is installed in the groove “about the lugs 0 of the frame 4 and in the shackle II of the bar 5. In this way, the connecting link is formed. From the longitudinal displacements, the finger 7 is fixed by means of a bolt 12. On the frame 3 of the trolley I two lodgments 13 and 14 are rigidly fixed, and on the frame 4 of the trolley 2 lodgments 15 and 16 are movably mounted. These movable lodgments can be mounted, for example, on cage rollers ( not shown). Making the cradles movable prevents the influence of torque and load when turning one of the frames of the carriages relative to the other carriage around the longitudinal axis of the vehicle.

The vehicle has elastic elements placed at the ends of the rod 5.

Each of the elastic elements is made in the form of a pre-compressed spring 17 installed in liners 18 located in glass 19 passed through rod 5. Regulating elements located in the form of flanges 20 connected to the rod by means of bolted joints 21 are located on the front sides of the glass. On the brackets 22 of the U-shaped frames 3 and 4 carts mounted pushers made in the form of screws 23. They are passed through the holes 24 of the flanges 20 and are in contact with the inserts 18. The fastening screws 23 8 each bracket 22

osungestileno by means of a nut 25 and a lock washer 26.

With an unloaded vehicle, the lodgements are adjusted so that they are at the same level with respect to the rails level, for this by adjusting the screws 23, they are positioned so that the inserts 18 contact the flanges 20 in the cups 19.

Thus, between the inserts and the flanges: and no clearance is allowed. At the same time, by the same adjustment of the screws, the finger 7 is positioned in the middle of the groove of the eyelet 10, moving it relative to the hinge attachment of the second end. Due to such an installation of the thumb, the possibility of mutual rotation of the carts relative to each other along the axis of the vehicle is achieved.

When loading cargo 27 on a vehicle, non-simultaneous contact of the cargo with all lol-semektamk is possible. At the initial loading moment, the load is in contact with one of the extreme lodgements 16 or 13. When the force reaches the lodgement, for example 13, which exceeds the force of preliminary pressing of the spring 17 located closer to this lodgement, the frame 3 together with the trolley will rotate relative to the longitudinal axis. wheels of this cart (fig. 2). When the trolley is rotated, its second cradle, in this case 14, will be lifted until it is in contact with the load. After the load is supported on the second bed 4, it will be lowered and the bed 13 will be raised. At the same time, at the moment of raising the bed 14, the turn and the frames 4 together with the carriage 2 will take place, with the result that the bed 15 will rise, and the bed 16 will go up; its At the end of the loading of the cargo, all the lodgements take up a position under the cargo.

When transporting a vehicle without a load, only the reciprocal rotation of the frames of the carriages relative to the longitudinal axis of the vehicle within the limits of the movement of the finger 7 in the slot of the al.

In this case, the springs 17 do not enter into operation, since kx preliminary podcasting is selected on the basis of the dynamic loads applied to the vehicle during its movement and uneven distribution of the weight of the frames of the trucks relative to the longitudinal axis of the wheels of these trucks, taking into account the weight of the rod five.

When a vehicle is moving with a load on an uneven section of the track, for example, about a rail junction zone, a slight inclination of the frames is possible as well as when loading a load. Then, in this case, the frames of the carriages and the movement of the twin lodgments will be rotated according to the same principle as when loading.
