Description

Arrangements are known for automatically braking a train at certain points on the track when it exceeds the maximum speed set for it, and consists of arms that interact with each other, of which one is mounted on the train and the other on the track, the latter being arranged, fixed or associated with a semaphore drive. Nor are the devices for indicating on the cart the speed of movement of the latter, consisting of an electric generator driven in rotation from the axis of the slopes, supplying a solenoid, the core of which is connected with the device for this speed.

In the proposed device with a solenoid core, a plate is movable with it, which serves as a stop for the lever connected to one spool of the brake valve; another valve of this valve, connected by a spring with the first valve, is connected with a lever that interacts with the stop. The indicated plate is provided at its end with a cut-out that serves as the day of passage of the lever, so that at a speed lower than the set, both spools can turn to the same angle and thereby prevent braking. The device uses a solenoid arrow connected to the core of an instrument indicating the train speed and a writing device of a recording recorder.

In FIG. 1 shows a top view of the device; FIG. 2 and 3 are two side views of it (behind the R on the side of the engine); FIG. 4-tap connected to the air brake of the locomotive.

A dynamo 1 (Fig. 1-3) is driven by gear wheels 16, 7 wheels / 8, mounted on a shaft, which is located on a steam locomotive; and with the help of gear wheels 14, 15 and several worm gears, drum 8 rotates one turn in about 500 km of the distance traveled. On. This drum is superimposed with grafted paper, on which a pencil 9 scrolls a curve during the course of the train, the horizontal distance is measured, and the speed is shown vertically.

Dynamo 1 electrically energizes a solenoid 2, attached vertically to the frame. The solenoid 2 freely enters an iron core 5 attached to the rod 12, held by the spring 4, resting its upper part into the rod 11 mounted in the shaft 12, and the lower part — into the guide 6. The rod 12 can be moved while attached to the guide 6 the pipe. Above the spring 4, a pin is inserted into the rod 12, onto which a lever 10 is loosely mounted with its oblong hole; a pencil 10 is attached at its other end 9. A chain 13 is attached to the upper end of the rod 12, wound on the axis of the tachometer 62 ko eco, so that when lowering The chain 13, winding down from the wheel and pulling the spring, turns the arrow of the tachometer downwards.

A plate is attached to the core 3 from above, at the end of which a rod 7 is embedded, passing its upper end into the guide 5. Plate J, which has a free end, is attached to the lower end of this rod.

In its lower part there is a through cutout 48 (Fig. 3). .

As the locomotive 7 moves, the dynamo 7 generates an 8 electric current, which, passing through the solenoid 2, draws into the last core 3, as the current weakens, it is returned upwards by the spring 4,

Since the depth of intake of the core into the elenoid depends on the current strength in it, which, in turn, depends on the speed of the locomotive, the core 3 will then lower, then rise by the action of the spring 4, replacing the rod 7 itself with it pencil 9 will draw a curve on drum 8, which can be judged on. On what part of the route and how fast the train was going and where were the stops. The tachometer needle 62 shows the speed of the train. Plate 5 is bonded to the core, having a notch 48 at the end.

Another component of the device consists of levers 25, 26 and 27 located under the steam locomotive (Fig. 2), which interact with the track instruments and actuate the engine whistle and rotary valve.

These levers, arranged as pivotal on an axis fixed in bracket 46f, are located at some distance from each other, somewhat obliquely to the rear part of the locomotive; they are held; and after turning, each spring is returned to its place by a spring 30 (Fig. 2 and 3).

The levers 25, 26, 27, made of different lengths, interact with the corresponding path-lugs located parallel to the rails at a known distance from each other. The lever 25, having hooked on the pin of its travel stop, rotates and turns the lever 28 coupled to it, to which is attached a tow of 4 & held up to the rollers behind the driver's booth, to the lever pivotally connected to the locomotive's hand lever.

The lever 26, made slightly shorter than the lever 25, hooking on the pin of its travel stop and turning, actuates the engine locomotive brake valve when the latter exceeds the set travel speed.

The lever 27 (which is shorter than the lever 26) actuates the brake valve only if the semaphore is closed, i.e., it prevents the locomotive from passing to the station with the semaphore closed; regardless of the speed of the train.

The air brake on the engine is connected by the air duct 31 to the valve of FIG. 4) consisting of a vertical hollow column, equipped with a bottom projection above which there are two openings 52 and 40, which open and close onto the column and rotate the spools 21, 22, which act as if the handles of the valve. In these rings, in one line with the holes in the column, there are ellipsoidal holes in the rim 27-through 39 ring outside, in the 22-sided ceramic ring 33, going upwards under the middle ring and opening out only through the through hole 33 of the middle ring. This position of the ring is taken automatically in those cases when the train must be stopped by a brake. Between the two rings of the spool 22, located forked, a ring is inserted, having on the underside of the hole 33 of the lever all three rings are mounted on the column, therefore a hinge is formed. lever 20 and spool 22 and move closer to each other and move up to the order. 42 (Fig. 1). If the spool 22 is turned in the direction of the lever, then the latter, being coupled with the spool 22 by the spring 44, will also rotate without changing its relation to the first, and will at the same time move the lever 20, against which the cutout 48 falls against the plate 5 (Fig. 1 and 3) through which he will freely pass. Then, although the channel 33 of the spool ring 22 will be above the hole 32 in the column, the air will not leave it, since the channel 33 will remain closed at the bottom

side of the lever ring 20

If the speed of the locomotive exceeds the set speed, then the plate 5 will fall into the slot of the floor, and against the lever 20 there will no longer be a notch 48, but the body of the plate 5, into which the lever 20 resists and does not move the lever 20. In this case, the spool 22, moving cs, fit to lever 20 and channel J5 cBoero; rings will connect the hole 32 in the column with the hole 33 of the ring of the lever 20.

Air through the opening 52 of the channel 33 and the opening 33i exit T; from the column of the crane to the outside, as a result of which the brake valve of the engine will come into effect.

Above the rings of the lever 20 and the spool 22, a fixed ring without a lever is fixed on the column with a screw, on top of which a ring of spool 21 is loosely attached to K in the upper part of this ring there is a recess forming some space between the column and the ring wall; A spring 55 is inserted into this space, tending to turn the ring to the right, why the spool 21 is always pressed against the retaining pin (not shown in the drawing), and the hole in the column 40 is closed. When turning the spool 12 a few degrees to the left, the hole of the Rego-ring will be above the hole 0 in the column and release air from the latter, which will also trigger the brake valve of the engine.

At the upper end of the column, on top of the spring 38, another fixed ring is screwed on and fixed with a screw so that between these rings and the ledge of the column the rings of levers can freely rotate by a certain amount ..

. When installing the spool ring 21 with a hole 39 above the hole 40 in the column, the spring pivot lever 36, mounted on the spool ring 21, will fall into the recess 37 of the fixed ring and hold

but in this position until the said pin is removed from the recess 57 by pushing the lever 36 away from the valve by hand, after which the ring, by the action of the spring 38, will turn and return the spool 21 to its original position.

The spool ring 22 is connected by means of hinges with a lever, when the latter, when the set speed is exceeded, hits the plate 5, the spool 22 moves to the remaining lever and channel 33 of the second ring, connects the hole 32 in the column with the hole 33, the average lever ring 20, lever pin B4 55 enters the recess 41 of the upper ring of the spool 22 and keeps the rings in such a position until the handle S5 is pulled out and the pin 34 is removed from the recess 41. After that, the ring of the spool 22, with which the spring 43 is fastened, will turn w in place and the hole 52 zakroets column. . 23, 24 are arranged so that the upper end of the lever 24 is located above the spool 22. When turning left, the levers 25, 26, at the time of their interaction with the pins of their track pads, the upper ends of the levers 25,24 move to the right in the direction of 54, 64 and turn: - lever 54-spool 21, and lever 25-spool 22, which at the same time act as described above.

The track stops are fixed at the corresponding points on the way from the right side along the train to the station; one of the setpoints is set in the place where the dane: whistle is to be actuated, after which the train speed must be reduced, and the other is closer to the semaphore, in the place where you need to check the set train speed.

The semaphore abutment is placed at the semaphore and retracted to the non-operating position when the semaphore OT1FYTII.

When the semaphore is closed, the lever 27 engages the track stop pin, rotates - and turns the spool. 2 /, which opens the hole 40 in the column with its ring, which activates the engine brake valve.%

To use the target device, it is mounted on a locomotive / and on the road pavement on the right side of the station, three rest stops are installed. Passing over the first stop, the lever 25 engages with its pin and automatically actuates the whistle, regardless of the speed of the locomotive. After the indicated whistle, the driver must shorten the train and move to another stop of the lever 26 at a speed not higher than that set, otherwise, when hooking Zrychag 26 for the pin of the second stop and turning the spool 22 and levers 2 and 20, the latter will be abutted into plate 5, because in this case, i.e., when the stroke speed is more than established, the notch 48 in the plate 5 will be below the lines of the lever 20. As a result, the spool 22, extending the springs 43 and 44, will approach the lever.

the hole 52 in the column with the 55-ring hole and will let the air out of the air line, which will activate the brake valve of the steam train. If the engine passes over the specified stop with the set speed or lower, the lever 20 will pass into the cutout 48 and. after the spool 22 is released from the lever 23, it will return with the levers 20 ° and 20 back to its place, the brake valve will not act, and the train will pass freely on to the semaphore. The last semaphore stop of the lever 27, as indicated above, will miss the train and will not brake it only when the semaphore is open.

Track stops for an automatic driver can also be temporarily installed, replacing existing signals at all those points where a locomotive whistle or a train speed reduction is required, which must follow the whistle (if the track and bridges are faulty and repaired).

It is possible to control the course of the train at several points of the path at different speeds, for which in plate 5, instead of the longitudinal slot 48, there must be, at a certain distance from one another, openings for the passage of the lever 20, each at a point corresponding to the speed of steam locomotive.

The operation of the pre-planned device is described as the train travels to the station. During the course of the train from the station, all the stops will appear on the left side of the dog. that is, on the other side of the levers on the train, why levers 26. 26 and 27 will remain inactive.

If necessary, so that lever 27 acted, and when departing from the station, i.e., that the train did not have an Mdr to leave the station with the semaphore closed, on the other side- A parallel pipe is placed parallel to the base post, and the same other stop and its rope, the passage under the rails in the pipe, are joined by the first column cable. In such a case, the semaphore opening will always turn the pins of both stops when the train passes in both directions.

The subject matter of the invention.
