Abstract
The utility model relates to a measuring instrument suitable for central base horizontal lines of railway rail surfaces, which comprises a rail caliber rule; a bracket is arranged on the central position of the rail caliber rule; the rail caliber rule is connected with one end of a straight rule by a pivot on the bracket, and the other end of the straight rule is combined with an adjusting screw arranged on one side of the central position of the rail caliber rule; a level instrument and a laser transmitter are arranged on the straight rule; the laser transmitter is arranged on a vertical center line of the rail caliber rule. The utility model adopts the structural characteristics, and thereby, the utility model solves the problem that people crouch or fall flat on the ground to take measurement, and meanwhile, great train operation accidents of train overturning can not occur because ballast is forgotten on the rail surface.
Description
The utility model relates to a kind of horizontal survey meter of railway rail level center reference that is applicable to.
Electrically-driven car generally operates on China's railway line.Setting up the electrically-driven car power line or to setting up power line when maintenance, very strict to its spatial coordinates accuracy requirement, its error must not be greater than 20mm.Currently used metering system is the method for " spirit level range estimation ", that is: when track is in linear section, the people stands in the opposite side of track, two rail levels of eyes and track are estimated a bit that is arranged on track one lateral brace in line, this point is calibrated the bench mark that is used as spatial coordinates carry out DATA REASONING; When track is in curve section,, after the rail level level by spirit level check and opposite side, carry out above-mentioned range estimation operation again because two rail levels, then must be selected the suitable ballast of thickness not at same horizontal surface on the low rail level of rail level.Though this method is simple, needs personnel to squat down or fall, and once took place several in history and ballast forgotten the great train operation accident that on rail level, causes train overturning.
The purpose of this utility model provides a kind of horizontal survey meter of railway rail level center reference that is applicable to regard to being at above-mentioned existing in prior technology deficiency.
The purpose of this utility model can realize by following technical measures:
The utility model comprises track slide calliper rule, is provided with a support being positioned at described track slide calliper rule center position, combines with an end of a ruler by hinge on described support; The other end of this ruler combines with the set screw that is arranged on track slide calliper rule center one side; Described ruler is provided with a level indicator and a laser transimitter, and described laser transimitter is positioned on the track slide calliper rule vertical center line.
Advantage of the present utility model just is by track slide calliper rule are set, when measuring, the track slide calliper rule are stuck on the rail, by adjusting described adjusting bolt the ruler that is arranged on the described support is horizontal, operation setting the laser transimitter emission of lasering beam on the ruler to be arranged on track one lateral brace a bit, this point calibrates the bench mark that is used as spatial coordinates and carries out DATA REASONING, thereby solved the problem that personnel squat down or fall and measure, also can not take place again ballast is forgotten the great train operation accident that causes train overturning on rail level simultaneously.
Fig. 1 is a front view of the present utility model.
The utility model describes in further detail below in conjunction with specific embodiment (accompanying drawing):
As shown in the figure, the utility model comprises track slide calliper rule 1, is provided with a support 2 being positioned at described track slide calliper rule 1 center position, combines by the end of hinge 3 with a ruler 4 on this support 2; These ruler 4 other ends combine with the set screw 5 that is arranged on track slide calliper rule 1 center one side; Ruler 4 is provided with a level indicator 6 and a laser transimitter 7, and described laser transimitter 7 is positioned on track slide calliper rule 1 vertical center line 8.
