FIELD OF THE INVENTION The invention relates to railway transport and relates to the DPF devices for uncoupling wagons during the disbanding of trains.

The goal of innovation is to increase reliability.

FIG. shows the device in the working position, general view; figure 2 - the mechanism of rotation of the roller with a mechanism for fine tuning, oblits view; on fig.Z - mechanism.turn roller, general view; Fig. 4 is a diagram of the connection of the chambers of the lift cylinders and the roller rotation mechanism; on fig.Z - the mechanism of fixation.

The trolley 1 has an axis 2 with a rod 3 that is movably attached to it, a power cylinder 4 of the fixation mechanism, connections the rod 3c with trolley 1, the force cylinders 5 of the search mechanism connected to the trolley 1 through sub-supports 6, the slide valve 7, associated with line 8 ni.icoKoro pressure, and wheels 9 With axles. Supply of compressed air to the working cylinders can be carried out right at the initial position of the truck through the air hitch. In this case, the cart must be equipped with a reservoir for storing compressed air. A shock absorber 10 and a locking mechanism with an anvil 11 are fastened in the upper part of the rod 3. In the upper part of the cylinder shaft 5 there are plates with guides 12 and a spring 13 that bind the rods together, as well as the shaft turning mechanisms I settings. Trolley 1 is mounted on rails 14, made in the form of channels, located between the rails. The base part 15 is installed on the carriage,

This mechanism of rotation of the roller is based on the side wall of the body of the automatic coupling, and the rotation of the roller of the elevator is ensured by rotation of the drive shaft, achieved by the interaction of the screw cuts of the drive shaft with the projections threaded on the rod.

in contact with the shock absorber 10 and the closing mechanism of the rod 3,

The fine-tuning mechanism comprises a roller 16 fixed on the bracket 17 and supported in the working position in the automatic coupling in the zone of transition from the head to the shank, and roller 18 fixed on the brackets 19 and supported on the side wall of the automatic coupling from the side of the small tooth. The brackets 17 and 19 are attached to the cylinder 20 of the roller rotation mechanism.

The roller rotation mechanisms comprise a drive shaft 2 with a screw thread 22 and a protrusion 23, a cylinder 20 with a rectangular bore, and a rod consisting of parts of rectangular 24 and circular 25 sections. A protrusion 26 is made on the rod, which engages with the thread 22 of the drive shaft 21.

The rodless cavity 27 under the piston of the cylinder of the automatic clutch lift roller's rotation mechanism is connected to the rodless cavity 28 of cylinder 5 through the piston rod 29, which has a check valve 30 and valve 31 that opens when the roller 1 is touched in the automatic coupling shank, and the rod cavities are permanently linked together.

The locking mechanism consists of the stop 1 I, the torsion 32, the pusher 33 located in the oval hole of the rod 3 and connected to the torsion 32 through the lever 34 and with the cylinder rod 4.

The device works as follows.

After giving the signal about the disengagement of the cars, the spool valve 7 connects the rodless cavity of the cylinder 4

with line 8, and the rod cavity of this cylinder - with the atmosphere. After the rod 3 has reached a vertical position, the spool device 7 connects the rodless cavity of the cylinders 5 to the line 8 and the rod cavity to the atmosphere. At the same time, the car strikes the base part 15 against the shock absorber 10 located on the rod 3, and simultaneously with the start of movement of the pistons of the cylinders 5, the carriage 1 begins to move and the rod 3 inclines, compressing the air in the cylinder 4.

When hitting the bar 3, the base part of the car first deflects the stop 11 due to the torsion 32 torsion. The pusher 33 is pressed to the rear (in Fig. 5 to the zero edge of the oval hole. When the base part touches the bar with the bar 3, i.e. after compression the damper located in the upper part of the rod 3 (not shown) lynop 11 returns to its original position and, after restoring the vertical position of the rod, prevents it from moving away from the base part of the car.

When the fine-tuning mechanism reaches the level of the automatic coupler's head, the rollers 16 and 18 deflect the cylinders from the vertical position and, thus, accurately base the roller's rotation mechanism relative to the automatic coupler housing. After the roller 16 stops in the automatic coupling shank, the valve 31 opens, connecting the rodless cylinder 27 of the roller rotation mechanism to the rodless cylinder 28 of the lifting cylinder through the hollow rod 29. The rod cavity of the cylinder 20 is permanently connected to the rod cavity of the cylinder 5 and is thus connected with the atmosphere.

The drive shaft 21 of FIG. 3), which is connected to the rod, first moves progressively with it, then, after stopping the opposite side of the lift roller 2C, begins to perform a rotary motion, turning the lift roller and uncoupling, thus, the coupler. After the process of uncoupling is completed, the spool valve connects the schtock cavities of 1SHLINDER 5 and 20 with the main, and their rodless cavities through the check valve 30 to the atmosphere. In this case, the roller rotation mechanism departs from the roller counterweight and lowers0

with in the initial position. After that, the spool device connects the rod end of the cylinder 4 with the line 8, and the rodless cavity with the atmosphere. In this case, the pusher 33 (FIG. 5) moves the cylinder 4 rod to the front (in Figure 5 - to the right) edge of the oval hole of the rod 3, turning the torsion 32 with the stop 11, KOTophtfi frees the base part IS of the car from engagement, after which the cylinder 4 rotates the rod 3 around the axis 2 to its original position. The cart is stopped and returned to its original position by a return mechanism, made, for example, in the form of a chain with pushers connected to the engine by a pneumatic cylinder, or by other known methods.
