Definitions

a device for indirect indication of rail axis, in particular a bridge rail, is an object of this invention.
Such a device referred to in the publication titled " Engineering Geodesy” by W. Janusz, collective work, volume II, PPWK, Warsaw 1994, page 445 , a special levelling head for indirect reproduction of rail head, namely a scissor clamp, provided with immovable grips at the end of the arms, touching lateral surfaces of the rail head.
the levelling head is aligned on the rail the way that, once aligned, the centre of the target is situated in the vertical plane containing the rail axis.
a levelling head namely a scissor clamp provided with four rotating rolls at the end of the arms, two pieces at each end. The rolls move along lateral surfaces of the bridge rail head.
a geodesic aiming device is installed on the clamp.
the known special levelling heads provided with grips at the end of the arms have to be moved along the rail and fixed in other measuring point, which is toilsome and time-consuming, and also requires the staff intervention.
the known levelling heads though enable movement of the instrument along the rail, do not assure stability of the device, which is not propitious to safe and failure-free realization of measurements.
the essence of the invented device for indirect indication of rail axis consists in that at the end of each arm of the scissor clamp located is a rectangular prism roll tilt limiter with an opening. The rolls are installed on self-aligning bar.
the invented device for indirect indication of rail axis enables its safe movement and a stable position on the rail, by pressing the device to the upper surface of the rail head, thanks to self-aligning rolls that change the deflection direction, according to the turn of the device movement direction. At the same time, it allows to more precisely indicate the rail head, and thus the rail axis, which helps to obtain more accurate results of the measurement.
the invention object a real model, has been described on the drawing that illustrates a scheme of the device for indirect indication of rail axis.
the invented device is composed of scissor clamp 2 with rolls 5 located on self-aligning bar that are connected with the arms ends.
the scissor clamp 2 has been installed on trolley 4.
At the end of each arm located is a rectangular prism roll 5 tilt limiter 3 with an opening that points out magnitude of the roll 5 deflection of the vertical.
a target 1 is located at intersection of the scissor clamp 2, that indicates the axis of the rail head, and thereby the rail axis.
Rolls 5 rotate along lateral surfaces of the rail head, and their deflection from the vertical is changing according to the turn of direction of the invented device movement. Location of the target 1, and thereby that of the rail head, which corresponds to the rail axis position, are readable at determined places.
