Description

BASIC Auth. St. No. 52127 described an instrument for recording the operation of shunting locomotives.

The proposed device is a modification of the above, consisting in the fact that the writing device makes a separate recording of the speed of a locomotive as it moves forward and backward and records the path traversed by the engine.

FIG. 1 shows a general view of the device, FIG. A 2-node instrument recording a speed of a locomotive, in FIG. 3 a tape drive mechanism and in FIG. 4 sample tapes.

A ratchet 1 is mounted on the axis of the minute wheel of the watch, on its teeth a part of the “left foot of the bracket 2 slides, and a fork 5 is fixed on the top foot so that it can easily rotate with its sleeve and move freely along the axis 4 up and down together with bracket 2. The legs of bracket 2 slide along the bar, covering it and preventing the bracket from rotating when the axis 4 rotates. The fork 3 rotates with the axis 4, for which its horns are inserted into the block 5 fixed rigidly on this axis.

Axis 4 rotates in proportion to the speed of the locomotive. Above the pad, an axle b is freely mounted on the axle, at the ends of which the gear wheel 7 and gear 8 are pressed in, resting on bridge 9, mounted on the watch case with the help of columns 0. A bearing 11 is located on gear bridge 8 on the bridge, serving as a bearing for the horizontal axis 12, on which the face gear 13, which meshes with the gear 8, is tightly mounted, and the gear sectors 14 and 15, which are attached on both sides to the roller J6 in such a way that the gear sector 14 is reversed tine down and find c in engagement with the upper end of the toothed rack 17, and the toothed sector 15 is set up with teeth upwards and is engaged in the lower end of the rack 18. The latter is also engaged with C gear 19, which is close to half / 5 and mounted on axle 20, on which, besides this, there is another gear 21, which is coupled with a compensating rail 22. Axis 20 is inserted into an additional bridge 23 mounted on the second bearing 24 for axis 12. To move up and down the toothed racks 17 and 18 on m.Ostics 9 mounted frame 25 with two for the slats 22 - frame 26 with one scenes. The strips 17 and 18 are intended for mounting writing devices on them (not shown in the drawing).

. In the lower part of the device are placed parts designed to record and record the distance traveled. A drive shaft 27, in which the lower end of the axis 4 is attached with the helical spring 28 fitted, is fitted with a conical pinion 29 which meshes with the gear 30 mounted on the differential axis. A drum 31 is reinforced on top of the planetary differential mechanism, the upper section of which is made along a helical line. When the drum rotates along the helical roller, the roller 32, mounted on the leg of the slider 33, and causes the roller to rise until the roller passes through the highest point of the screw drum, after which the slider falls down until the roller reaches the lowest point on the cut of the drum .

The slider is designed to reinforce the writing device on it, putting on the tape a line indicating the length of the path traveled during the complete revolution of the drum. Depending on the need, the drum can be connected to a digital counter.

Recording can be made either on a paper disk, worn on the axis of the hour wheel, or on a tape, driven by gear 34, worn on the axis of the intermediate wheel hours. In this case, a tape mechanism is used, mounted on the shelves 35 of the device and executed as follows:

In the frame, 5, a drive roller 37, a winding coil 38 and a winding roller 39 are mounted, the gear 40 and the bevel gear 41 are tightly mounted on the roller shaft 37; The winding coil 38 has a frictional engagement with this axis. The friction clutch is created by the coil spring 42, compressed tightly mounted on the axis of the coil toothed wheel 43, which engages with the wheel 40. In order that the rotation of the coil is not affected by the ratchet on the upper frame bar, the coil is separated from the last disc 44 or nut . The coil 38 makes the same number of revolutions with the roller 57 until its diameter with the tape wound on it exceeds the diameter of the roller 37, then the coil 38 will begin to slip and the tape will be in the tensioned state all the time. The unwinding reel, in order to avoid premature unwinding and loosening of the belt tension, is decelerated by the spring 45 during rotation.

The tapered mechanism is installed on the shelf 35 of the device and is reinforced by the legs 46, the gear wheel 47 engages with the gear 34. Since the wheel 47 is pressed onto one sleeve with the bevel wheel 48, and the latter is engaged with the gear 41 , then the clock causes the drive roller 37 to rotate uniformly, thus ensuring uniform movement of the tape on which the recording is made with writing devices. . The operation of the instrument is as follows. .

During the course of the clock, the ratchet / makes one revolution per minute, and the claw of the clip 2 sliding along its teeth of the spring by the action of the spring 28 at regular intervals of time, then inserts the horns of the fork 3 into the intervals between the teeth of the wheel 7, then displays them back. If at the same time

the drive axle 4 rotates, then the pad 5, turning the fork entering into it, causes the turn 7 and gear 8 to turn until the fork horns are pulled out of the gaps between the teeth of the wheel. This rotation is transmitted to the face wheel 13 and the gear halves 14 and 15 located on its axis. Depending on the direction of rotation of the axis 4, depending on the direction of movement of the locomotive, engages either the half 14 with the rail 11, or the half 15 with the rail 18, therefore, the compensating rail 22 will also move. As soon as the horns of the fork 3 cease to act on the wheel 7, the entire system will be affected by the force of gravity of either the rail 17 or the load on the rail 22 and all parts will return to their original position under the action of this force of gravity. During the movement of the rails 17 and 18, the feeding devices located on them will draw streaks on the tape (Fig. 4), the rail 17 from bottom to top, and the rail 18 from top to bottom. The length of the lines will be proportional to the speed of the locomotive. Due to the uniformity of movement of the belt, the streaks will be equally spaced from each other. If this distance is multiplied by the number of teeth of the ratchet, we obtain the length by which the belt moves in one minute, and vice versa, knowing this length, we can determine the duration of the locomotive station.

The speed of movement is determined by the length of the chip, taking into account the recording scale. The length of the traversed path is recorded at the bottom of the tape and is carried out with the help of the drum 31 without any difference in the direction of movement, since the drum is connected to the drive shaft 27 via a differential. By knowing the length of the path on which the drum makes a full turn and, taking into account that it is graphically represented by the length of the vertical line H, you can determine the length of the path traveled. You can determine the shape. Lgg hi + nH + h2, where n is the number intervals between vertical lines.
