SU10507A1 - The device for shooting cross-section rail crosses - Google Patents

Description

The proposed device aims to quickly determine the wear of rail crosses by removing the IH profile of the paper.

In FIG. 1 is a front view of the device; FIG. 2-section A-B in FIG. one; FIG. 3-section along the C-D in FIG. 2, and FIG. 4-view of the device in perspective.

The device CONTAINING of the rod 1, fitted along the entire length with a toothed rack, two removable clips 2 and carriage 5, can be installed in any crossbar, both in transit and removed, using the above clips 2 with clamping screws 3,

The carriage 5 is provided with a tube 7, for guiding the needle 8 with a pencil 9, and the gear 12 interlocking with the toothed rack on the rod 1 and driving the drum 10 by means of a cut at the end of its axis 16. The two rollers 11 serve to press the paper tape 14 to the drum 10. When the carriage moves along the rod 1, the gear wheel 12 rolls along the rail and

rotates the drum 10, which carries the paper tape 14 along with it, and pencil 9 draws on it a horizontal straight line .1INII serving as the axis when combining the profile removed from the cross under study with the profile of the normal cross. To remove the profile, it is enough to press a finger on the pencil 9 until the end of the pin 8 touches the cross and to move the carriage 5 along the rod 1; at the same time, pencil 9 will draw the profile of a cross on a paper tape. The profile that appears on the 1ent will differ somewhat from the actual one, due to the fact that the needle end is not an ideal point, but a spherical surface of a certain radius; therefore, such a profile can be compared only with a profile taken from the same instrument with a normal cross. For convenience, the drum 10 and two rollers 11 are enclosed in the holder 13 and together with the latter can be removed from the carriage. A spring 15 serves to lift the pin 8. The carriage 5 and the clips 2 are provided with keys 6 to prevent rotation around the rod 1 Pass the patent.

A device for shooting a cross-section rail cross, characterized by the use of a fixed fixed cross, in its transverse direction, by the weakness of adjustable clamps 2-2, a toothed rod 1 with a carriage 5, carrying rotating, moving as it moves along the rod, a drum 10 and a spring pin 8 supported by a cross and provided with a pencil 9 for drawing a curve on a roll of paper moved by a drum.
