Abstract

The utility model discloses an electronic digital track gauge. On a common track gauge, the original track gauge measuring lengths of two steel rails and horizontal position disparity data by a graduated scale is designed into a track gauge displaying digits by means of electronic digital measurement, see figure 1, and when measuring breadths of the two steel rails, a liquid crystal display equipped with an integrated operational amplifier shows digits of breadths of steel rails under the movement of a semiconductor reluctance sensor chip (8). When measuring the horizontal position disparity of the two steel rails, the liquid crystal display equipped with the integrated operational amplifier displays digits of the horizontal position disparity of the steel rails under the movement of a semiconductor magnetic induction chip (4).

Description

The electronic digital gauging rule

Affiliated technical field:

It is relevant with the gauging rule device of two one steel rail horizontal position differences that the utility model relates to the width of a kind of measurement two one steel rails.Especially by stand, fixedly the gauging rule formed of card base, bubble rotating disk manual adjustment formula level meter, handle, mobile handgrip, connecting rod, spring, sized panel, movable card base is relevant.Be relevant more specifically with the rule of gauging rule.

Background technology;

At present, the structure of the common gauging rule that uses on the railway is mainly by stand, fixedly card base, bubble rotating disk manual adjustment formula level meter, handle, mobile handgrip, connecting rod, spring, size window, sized panel, movable card base are formed.When measure two one steel rails apart from the time, grasp handle, finger is being pinched mobile handgrip, drivening rod, the connecting rod activity card base of ining succession, spring on the compression connecting rod, produce displacement, place then among two one steel rails, unclamp mobile handgrip, wherein an end fixedly card base be close to the wherein inboard of an one steel rail naturally, the movable card base of the other end is close to the inboard of another one steel rail.Size window from the stand is read the distance between the rail of the two poles of the earth.Simultaneously when measuring two one steel rail horizontal position differences, must save rotating disk on the spirit level with hand adjustment, through regulating repeatedly, when the spirit level level, just can read the dimensional data of two one steel rail horizontal position differences.Because it is the rotating disk on the spirit level is to use manual shift, thereby very time-consuming, special because be the scale numeral on the baseboard, the as easy as rolling off a log scale error that occurs, this brings operation loaded down with trivial details for the detection trackwork, and brings inconvenience, its inefficiency for staff's operating process.

The someone applies for a patent " the automatic adjustable type gauging rule of weight " now, it has overcome the loaded down with trivial details of manual shift, the horizontal position difference of measuring two one steel rails that can be automatic accurate, but the mechanical measurement mode that still keeps the sized panel rule, degree of accuracy is not high at positive and negative 1 millimeter, and still has the collimation error.

Summary of the invention:

Task of the present utility model provides a kind of novel gauging rule, and it is to control the distance of measuring two one steel rails and the horizontal position difference of two one steel rails with electronic digital, and speed is fast, degree of accuracy is high.

In order to solve above-mentioned task, the technical scheme that its technical matters that solves the utility model adopts is: on common gauging rule, original rule is set to semiconductor magnetic resistance sensing chip, an integrated computing amplifier and LCD are installed on the Dui Ying stand with it, digital display screen and control adjusting switch are arranged on the display.When semiconductor magnetic resistance sensing chip moves with movable pin, receive information by integrated computing amplifier and export to display again, demonstrate measured numeral from display screen then, thereby reach the width of quick measurement two one steel rails and the horizontal position difference of two one steel rails, demonstrate the purpose of numeral with electronic digital.

By the scheme that has adopted electronic digital to show in the above-mentioned solution.It has following advantage and effect: one; Speed saves labor during measurement soon less than 1.5m/s during measurement, has improved work efficiency; Two: the measurement data degree of accuracy is up to positive and negative 0.01 millimeter, and 100 times of original raisings compare; Three: it also has multiple function: the zero setting of one optional position, be convenient to relative measurement; The conversion of its two optional positions measuring unit, it is three in light weight, and volume is little, is easy to carry convenience operation.

Description of drawings;

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is the utility model gauging rule front view.

Fig. 2 is the utility model gauging rule vertical view.

With reference to accompanying drawing, in Fig. 1, fixedly card base [1] and stand [2] and electronic digital display [3] and [9] connect together, and are integrated Computing amplifier is contained in display [3] and [9] the inside, has on display [3] and [9] with reference to display screen [13] in the accompanying drawing (Fig. 2) and [17], Close key [14] and [18], zero setting key [15] and [19], measurement unit's key [16] and [20] are with corresponding the having of electronic digital display [3] Measure the semiconductor magnetic resistance sensing chip [4] of rail horizontal position difference, partly the leading of the measurement rail width corresponding with electronic digital display [9] Body magnetic resistance sensing chip [10], and semiconductor magnetic resistance sensing chip [4] and semiconductor magnetic resistance sensing chip [10] all can be at electronic digital displays [3] and in [9] interior survey face, can press the planned course proper motion.
