Abstract
The utility model discloses a kind of portable rail head abrasion measuring instrument, cannot determine to measure basic point during to solve and to measure rail wear at present on the line, cause the problem that measuring result error is large.It is made up of clamp and spiral chi, clamp side driving surface profile is consistent with surveyed rail standard section head and waist profile also can be fitted tightly, screw is had apart from rail head work hem width 1/3 place and side apart from 16 mm places under rail head tread at clamp end face, after two spiral chis with a scale rotate through screw, top withstands the rail head of rail tread after wearing and tearing and side respectively, can read the wearing valve of rail head of rail tread and side respectively.The utility model measures rail head abrasion accurate positioning, and survey precision is high, can provide failure-free Data support for rail maintenance, and easy to carry, is applicable to daily field work, low cost of manufacture, is easy to promote.
Description
Technical field
The utility model relates to a kind of portable rail head abrasion measuring instrument.
Background technology
Rail runs for many years on railway, and rail head abrasion highlight gradually on the impact of railway security.In order to ensure railway operation safety, " railway line the repair rule " requirement of promulgating according to the former Ministry of Railways, needs to safeguard rail according to rail head abrasion loss or change.In " railway line repairs rule ", the vertical abrasion loss of regulation rail head is measured at standard steel tread identity distance work hem width 1/3 place, side wear 16 mm places under standard rail tread are measured, the rail of different size defines corresponding abrasion loss, judges rail defects and failures rank according to abrasion loss.During actual measurement, wear away and the corrosion failure standard profile of rail because wheel contacts with rail, cannot determine to measure basic point when measuring rail wear on the line, thus cause measuring result error large.
Summary of the invention
The purpose of this utility model is to overcome prior art defect, provides a kind of portable rail head abrasion measuring instrument, can carry with, and the Measurement accuracy rail head abrasion when line upkeep, for the maintenance of rail provides reference frame.
The technical solution of the utility model is achieved in that a kind of portable rail head abrasion measuring instrument, be made up of clamp and spiral chi, clamp side driving surface profile is consistent with surveyed rail standard section head and waist profile also can be fitted tightly, screw is had apart from rail head work hem width 1/3 place and side apart from 16 mm places under rail head tread at clamp end face, after two spiral chis with a scale rotate through screw, top withstands the rail head of rail tread after wearing and tearing and side respectively, can read the wearing valve of rail head of rail tread and side respectively.
Preferably, spiral chi zero graduation and clamp flush with outer surface, scale increases successively along spiral chi end direction.
Preferably, spiral chi top conically, with rail contact surface diameter 1 ~ 2mm.
Preferably, screw is opened in clamp thickness direction inner end, and screw outer end is the smooth circular hole that diameter is slightly large, and when ensureing to measure, spiral chi scale part is outer not by thread failure at screw.
Preferably, relative with active side on clamp opposite side is provided with handle.
The utility model measures rail head abrasion accurate positioning, and survey precision is high, can provide failure-free Data support for rail maintenance, and easy to carry, is applicable to daily field work, low cost of manufacture, is easy to promote.

Fig. 2 is utility model works schematic diagram.
In figure, 1-clamp; 2-screw; 3-spiral chi; 4-handle; 5-rail.
Detailed description of the invention
Be further described below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of portable rail head abrasion measuring instrument, be made up of clamp 1 and spiral 3 chi, clamp 1 side driving surface profile is consistent with surveyed rail 5 standard section head and waist profile also can be fitted tightly, screw 2 is had apart from rail head work hem width 1/3 place and side apart from 16 mm places under rail head tread at clamp 1 end face, after two screw spiral chis 3 with a scale rotate through screw 2, top withstands the rail 5 rail head tread after wearing and tearing and side respectively, can read the wearing valve of rail 5 rail head tread and side respectively.
Spiral chi 3 zero graduation and clamp 1 flush with outer surface, scale increases successively along spiral chi 3 end direction, and scale overall length is about 30 mm, is convenient to reading; Spiral chi top conically, with rail contact surface diameter 1 ~ 2mm, is avoided measuring the excessive or too small measured error caused of contact surface; Screw 2 is opened in clamp 1 thickness direction inner end, and screw 2 outer end is the smooth circular hole that diameter is slightly large, and when ensureing to measure, spiral chi 3 scale part is outer not by thread failure at screw 2.Opposite side relative with active side on clamp 1 is provided with handle 4, grasps handle 4 during measurement, and the rail head of clamp 1 driving surface profile and rail and the web of the rail are overlapped.
To measure specification for the abrasion of 60kg/m rail head of rail, railway line is measured vertical abrasion and the side wear of rail head,
Clamp 1 driving surface profile is according to 60kg/m rail standard rail head, web of the rail size design.During use, driving surface is overlapped with rail 5 web of the rail and rail head and form reference measurement face, rotate spiral chi 3 with a scale above rail head, until top contacts with rail head of rail, contact position, at wide 1/3 place of rail surface, reads the vertical abrasion loss of rail head from spiral chi 3 scale; Rotate the spiral chi 3 of rail head side straps scale, until top and rail head contacts side surfaces, contact position is 16mm place under rail tread, reads rail head side wear amount from spiral chi 3 scale.Measure respectively rail head vertically wear away with side wear amount after, according to total abrasion=vertical abrasion+1/2 side wear, rail head can be calculated and always wears away, for rail maintenance provides failure-free Data support.
