SU57546A1 - Automatic device for recording the profile of the path traveled by a wagon - Google Patents

Description

Instruments are already known for the automatic zacis way profile, in which a friction system is used, consisting of two cones rotated by transmission from the axis of the vehicle, and two rollers moving along these cones, of which one roller is connected by means of a corresponding transmission with a pencil of a recorder the other is with the axis of the drum carrying the tape of this recorder.

In the proposed device for recording the profile of the track, a harmonic membrane is mounted on the wagon, communicating through a tube with an open vertical vessel filled with mercury; the movable bottom of the membrane is provided with a rod, which serves as a bond between the membrane and the bar that carries the above-mentioned friction rollers.

In the attached drawing of FIG. 1 shows a cart in a horizontal position with a membrane mounted on it; FIG. 2 and 3 - the same wagon in inclined positions; FIG. 4 is a diagram of an apparatus for automatically recording a profile.

A harmonic membrane (I) is installed on the wagon, which is connected via tube 19 to vessel 20 (Figs. 1 and 4). The tube vessel and membrane are filled with mercury. The membrane is provided with a rod 18 rigidly connected to the strap 2 on which the rollers are mounted - and 5. With the horizontal position of the wagon shown in FIG. 1, the rod 18 is in the middle position, which corresponds to the positions of the bar 2 and the rollers 4 and 8 shown in FIG. 4. With the inclined position shown in FIG. 2 and 3, due to the change in the mercury height h, the pressure of mercury on the harmonic membrane 1 and the rod 18, together with the bar 2 and the rollers 4 and S, deflects to the right or left (depending on the direction of tilt of the wagon).

In spite of the rotation of the cones 5 and 6, the roller 4 remains stationary in the horizontal position of the wagon. The fixed position of the roller 4 corresponds to the fixed position of the tape 11 with pencils (Fig. 4).

The roller 8 rests on the maximum diameter of the rotating cone 9

and, therefore, associated with the roller 8, the roll of the paper tape 13 moves at a maximum speed corresponding to the speed of the traversed path in a given scale.

With the carriage inclined, shown in FIG. 2 and 3, the rod J8, and hence the bar 2 with the rollers 4 and 8, are deflected to the right or left (depending on the direction of inclination), whereby the roller 4 begins to rotate and drives the tape P with the pencils.

At the same time, the roller 8 moves to a smaller diameter of the cone 9, whereby the speed of movement of the paper tape 13 is reduced.

Corresponding to the profiling of the cone 9 and the gearbox 12, the magnitude of the displacement of the tape 13 to the projection of the distance traveled on the horizontal plane is achieved. The corresponding profiling of the cones 5 and 5 and the gearbox 10 makes it possible to match the curve drawn in pencil on tape 18 with the road profile that the vehicle passes.

When the writing pencil reaches one of the edges of the tape 13, the registration continues with the next pencil. FIG. 2, the number 17 denotes a box that selects a pulse corresponding to the magnitude of the distance traveled.

The height of the location of the road above sea level is shown by counters 14 and 15, associated with the transfer to the tape rollers //.

At the initial start-up of the apparatus, the height above sea level is manually set on the meter 14 and 15, and then the meters are put into operation.

Counter 14 shows the height above sea level, and counter 75 shows the height below sea level. Counter 16 shows the value of the distance traveled.

The described device can be used to remove railroad profiles by driving them around a train or rolling roads with a special trolley, as well as determining the height of the location of the road above sea level.

The subject matter of the invention.

An automatic device for recording the profile of a path traveled by a carriage, using two interconnected friction systems consisting of cones rotated from the axis of the carriage and rollers moving along them, of which one roller is connected with the recorder's pencil and the other with the drum of the latter, characterized in that the harmonic membrane / communicating with the vessel 20 filled with mercury and fastened by a permanent link 18 with the carrier friction roller is used to simultaneously move the friction rollers to the right or left 2 bar.
