Description

The invention relates to devices for measuring the position of a railroad track in a transverse profile used on straightening machines.

The purpose of the invention is to improve the accuracy of measurements by reducing the effect of vibration on the master.

FIG. 1 shows a device for measuring the position of a railroad track in a nonepe Hcv, a profile in FIG. 2 — node 1 in FIG. one; but fig. 3 - device, cross section; in fig. 4 - the same. an embodiment; in fig. 5 - sweep the bottom of the tomb.

A device for measuring the position of a railroad track in a transverse profile is mounted on trolley 1. mounted on a tamping machine and comprises a housing 2, in which an axis 4 is suspended on axis 3 Lower surface 5 of antenna 4 and inner surface 6 of bottom 7 of housing 2 is They are parts of cylindrical surfaces with a center that coincides with the center of axis 3. The space between surfaces 5 and 6 is filled. By using a thin liquid 8 with the wetting perimeter inside this bottom surface 5 pendulum 4 and the inner perimeter of the bottom surface 6 of 7. The distance (5 (FIG. 2) between the bottom surface 5 of the pendulum 4 and the inner surface 6 of the bottom 7 is commensurate with the intermolecular distance.

ABOUT

at which intermolecular cohesive forces of the damping fluid 8 act.

The device also contains a recorder 9 of deviations of the pattern 4. The recorder 9 may consist, for example, of variable resistance. The lower part 10 of the treadmill 4 is made of high-molecular-weight plastic, for example, fluoroplast-4, in order to provide greater intermolecular coupling between the damping fluid 8 and the bottom 7. On the bottom surface 5 of the trough 4 and on the inner surface 6 of the bottom 7 there are grooves 11. The grooves 11 in (FIG. 3) serve to better wet the surfaces 5 and 6 and also (FIG. 4) to increase the contact area of surfaces 5 and 6 and provide an increase in damping capacity. On the surface 6 of the bottom 7 and on the surface 5 of the tangent 4, the grooves 12 are made to better wet the surfaces with a damping fluid 8. The grooves 11 (Fig. 3) and the grooves 12 (Fig. 5) serve to reduce the contact surface if necessary to reduce the damping and for increase the speed of the device when swinging the tandem 4 from vibration.

The grooves 11 are arranged perpendicularly forming these cylindrical surfaces, and the grooves 12 are parallel forming the corresponding cylindrical surface.

The device works as follows.

When the straightening-tamping machine is operating, vibrations occur in the zone of action of the working organ with an acceleration of about 10–20 g. This vibration is transmitted to the master 4. The damping fluid 8 due to the surface tension forces and intermolecular bonds with the surfaces 5 and 6 prevents the swinging of the master 4 from the vibration excited by the tamping machine. When making surfaces 5 and 6 of FIG. 4, the damping force is increased due to the increased contact area of surfaces 5 and 6. When surfaces 5 and 6 of FIG. 3 and 5, the damping force is reduced due to the fact that the contact area is reduced by

the size of the grooves 11 and the grooves 12. With a large mass of the tank, it is advisable to make surfaces 5 and 6 according to FIG. 4, and for small, according to FIG. 3 and 5. The grooves 11 and the grooves 12 provide equal surface tension due to the equal tension surfaces on the sides of the bow because of the capillary nature of the grooves 11 interconnected and the grooves 12.
