Description

The invention relates to a device for plotting on a map a moving object, such as a ship, airplane, cart, etc., a path with a constantly oriented tablet and with a map moved by a pointer or a writing device using a drive-driven lag etc., friction rollers, the main feature of which is that a rotary motion system and slide carriages are used to communicate the rotational motion map and the translational motion message placed on the device table. device

The proposed device is shown in the attached drawing, in which FIG. 1 gives the overall longitudinal view of the instrument; FIG. 2 is a top view of the device; FIG. 3 - longitudinal section; FIG. 4-side view of the device.

The proposed device with a mobile card performs the following work: 1) at any given moment the mechanism associated with the compass (predominantly gyroscopic) orients the map along the meridian, rotating around the axis of the device, regardless of whether the machine is moving or rotates in one place around its axis; 2) the map continuously moves at the appropriate scale relative to the fixed pointer in the direction opposite to the direction of the instrument, regardless of the change in the angle formed by the axis of the machine with a meridian (for example, when the machine is moving along a direct angle to the meridian); 3) when driving along a curve, the mechanism of the device must all the time move the map under the pointer to the magnitude (in scale) of the path traveled, and at the same time at all times at all points the same mechanism must orient the map in relation to the meridian; As a result, the complex movement of a tablet (map) along a curve must exactly match the distance traveled on the terrain shown in the map and at its scale.

In the proposed design of the device for plotting on the map of the traversed path (Fig. 3), all three types of map movements, namely: 1) rotation around one point (pointer), 2) movement along a straight line, and 3) movement along a curve are performed by one and the same two leading rollers 9 (right and left), rotated both by a compass and a flexible shaft of the track indicator, and the direction of movement of each roller 9 (right and left) and the number of revolutions each

and the length of the path both separately and in total at the same time.

A map of the area containing the location of the device and the path it is supposed to follow is placed on table 12, consisting of a metal board (Fig. 3) and hinged boards 13 (Fig. 2 and 4) attached to the housing 23 (Figs. 1, 3 and four). In the board of the table 12, the glass 14 is fixed centrally with lines intersecting at a right angle, opposite to the intersection point of which needle pointer 32 is installed with its point (Fig. 2 and 3), fixed on the axis of a special pressure device connected to the housing 23 by means of brackets 22 and 24.

The card lying on the table is positioned by the car's standing point at the moment under the pointer, after which the two upper pressure rollers 57 pressed down by the springs 27 are lowered onto the card, which are also movably fixed by carriages 26 on the axis 25 of the pressing device and which can freely rotate on their axes 28 in bearings 29 and 30. In the case of the device, a flashlight 2 / is placed on axis 4, on top of which, under glass M (Fig. 3), is mounted a second glass plate f9 with N, S, O, W lines and divisions in degrees ( Fig. 2). Axis 4 (Fig. 3) is connected in an appropriate way with the axis of the compass. The N-S line of the compass is aligned with the N-S line on the J9 plate of the instrument. Inside the flashlight 2 / (Fig. 3) an electric lamp 20 is placed, rotating with the flashlight and axis 4, depending on the rotation of the body of the machine and fixed on it the fixed case of the device 25 relative to the N-S line. An electric bulb receives electrical energy from a battery or other source through sliding contacts. On the map lying on the table, a standing line must be drawn with a pencil NS line through a point, then, when the current is turned on in the light bulb 20 and when scanning through the map, the J9 plate must be rotated under the pointer 32 (or a pencil replacing it). match the NS lines on the map and on the plate / I

Thus, the map, set by the point of standing under the pointer 32, is oriented along the NS line, and with the rollers 5 / lowered, the card is pressed against the two (right and left) rollers 9 that approach the map from the bottom through the table slots / 2, the device ready to use.

To rotate on a 360 ° map around the shaft 4, connected to the axis of the compass, a rigidly fixed central spur gear 2 was used, coupled with two side gears 2, of the same diameter (right and left) each of which rotates the same right and the left gear groups, differing from one another only by the direction of rotation, imparted by them to the right and left drive rollers 9 included in each group, having on their circumference a velvet groove for moving the pressure rollers pressed to them mouths of the locality.

When turning 360 degrees to the right or left around axis 4 (in the case of, for example, turning in place), the extreme (right and left) gears 2 also perform one turn, freely turning on axes x / 7.

On axis x 77, stationary in this case, the first bevel gears 1 are fixed above gears 2, remaining in this case also motionless (when turning in place), unlike the others, above conical gears that are similar to the lower ones and are that all of them (upstream) in any of the above three cases do not remain motionless, - and rotate both from the compass and from the track indicator. Using a special sub-carriage 76, a second bevel gear is included in the lower bevel gear; it rotates freely not only on its horizontal axis 75 in bearings 33, but is also able to rotate around the vertical axis 77 along the carriage b, around the vertical axis 77, driven by an atom moving freely rotating on the axis 77 well-spaced pair of bevel gears, rigidly interconnected gears, the upper of which are coupled with the upper bevel gear, rigidly together with the driving roller 9 mounted on the horizontal (upper) axis JO, rotated decoupling bearing / 5. On the right and left gears x 2, the drive squares / 7 (Fig. 3 and 1) are fixed, which, when turning gears 2, rotate the carriage / 6 with the same bevel gear on axis 18 / at the same angle. With the lower bevel gear fixed at the same time, connected to the axis 7 / with the worm gear 5 (below the gear 2) one turn of the carriage J6 will make two turns of the conic pair, which is included from above, which in turn will give these two turns to the drive roller 9 through the same bevel gear rigidly connected with the horizontal axis JO. Thus, with one revolution of the axis 4, each of the leading rollers 9 makes two revolutions, and, as is easily seen from FIG. 3, the direction of rotation is different. When turning the central gear 2 in a clockwise direction (viewed from above) one turn, the left driving roller 9 will make two turns from the observer, and the right one - two turns towards the observer. The drive rollers 9 are located at exactly the same distance x from the center of the transparent plates 7 and 79 and the distance between them exactly corresponds to twice their diameter.

Under these conditions, two turns of each of the rollers 9, made simultaneously in a different direction, moving the card pressed to them by the pressure rollers 57, exactly the same distance, but in a different direction, thereby turning the tablet (card) exactly 360 ° around the points of the car’s position, aligned with the pointer 32 with the centers of the glasses J4 and 7P, i.e., when turning the car in place at 360 ° (or another angle), the combination of the NS line of the compass and the map remains, and hence it is clear that for any turns of the mask will remain NS oriented.

In the case of a straight angle movement, formed by the N-S line and the maschine axis (direction of the path), remains unchanged, and therefore axis 4

(Fig. 3) should be considered as fixed, which, in turn, makes the fixed squares / 7 fixed on gears x 2, the carriage / 6 with support plates 33, while with the fixed carriage 76 it is freely reinforced in it on its horizontal axis / 5 the conical gear can rotate around its axis, being the transfer between the conical bristles coupled to it from below, mounted on the axis 77, and the upper conical pair, which rotates freely on the axis / 7 and transmits the rotation to the same driving rollers 9. When the rate does not change and still In this case, gear x 2 will only work as an indicator of the distance traveled. A flexible or other shaft, connected appropriately with a lag, a wheel of a maschine or another device that determines the size of the path traveled, is connected by a coupling to the worm axis 8 (Fig. 1) of the device at a certain gear ratio corresponding to the scale of this map. Bearing in mind the possibility of using maps of different scale, in order to avoid changing the details of the design of the device itself, it is necessary between the flexible shaft connected to the maschine wheel and the worm shaft 8 to turn on a special scale switch like a speed box. In this design, two worm pairs were introduced (focusing on approaching small scales) for each of the two groups of gears. Two screws 8, cut into the axle (Fig. 1), are coupled with gears 7, mounted on axis 3, bearing the screws B (Fig. 4), coupled with worm gears 5, rigidly connected. as well as the lower conical shtickets with vertical axes 77 (Fig. 3).

When moving along the straight and rotating roller 8 (fig. 1) of worm gears 5 (fig. 3), the lower bevel gears transmit their rotation to the middle and upper bevel gears to the driving rollers 9, and, as it is easy to see in the drawing, the rotation of both rollers 9 in this case, unlike in the previous case, will not be in a different direction, but in one, and the number of their turns will be the same, which will cause the card to move in one direction along the same direction as moving both right and left rollers 9 under pointer needle (or pencil ) 32; When the gear ratio corresponds to the scale of the map, the distance to the path covered is obtained.

I compared the first and second cases, that is, considering the rotation of the gears of both groups while simultaneously rotating both the compass axis 4 and the track meter axis 8, which occurs when following a curve, we can see that the leading rollers 9 (right and left) will have rotation around its axis inevitably at different speeds, and the ratio of the speeds will be inversely proportional to the radius of the arc described by the machine, and the presence of a large number of revolutions will be at that driving roller I which is located on the side opposite to the direction the one that will cause a displacement map for a pointer 32 of the curve, ie. e. in this case opredelits Location of the machine at the moment.
