Abstract
The utility model relates to an abrasion measuring device for steel rails, which is used to measure vertical abrasion and lateral abrasion of steel rails of railway operation lines, and comprises a fiducial positioning frame, auxiliary positioning screws on the fiducial positioning frame, a depth indicator which is used to measure the vertical abrasion and the lateral abrasion of steel rails. The utility model has the advantages of simple structure, visual and exact measuring data, quick up channel, down channel, safe operation, light weight and portability.
Description
A kind of measurement of rail wear based instrument is used to measure the vertical abrasion and the side wear of railway operation circuit rail.
Now gate-type measuring instrument and card grinding formula measuring instrument are arranged with the rail measuring instrument.The locating device of gate-type measuring instrument need block the rail head of rail and the rail flange of rail, block rail and take off action from rail slower, promptly upper track, the road is slower down, operating personnel are dangerous.Card grinding formula measuring instrument has testing needle, drafting system and stationary installation etc., and complex structure need be installed in during measurement on the rail, and its action is slower, and operating personnel are dangerous.
The purpose of this utility model is to avoid above-mentioned prior art weak point and a kind of measurement of rail wear based instrument is provided.
The utility model comprises locating device and measurement mechanism, locating device is the auxiliary positioning screw (3) in benchmark positioning framework (1) and the fixed step circular hole (5) that is contained in benchmark positioning framework (1), vertical survey circular hole (6) axis of benchmark positioning framework (1) is 1/3 of a rail head face width apart from rail (9) standard action edge, circular hole (7) axis is measured apart from 14 millimeters of rail (9) treads in the side, locating surface (8) is closely connected with rail (9) jaw portion, medial surface (16) and rail (9) web of the rail are closely connected, are that 1/3 place and the side measurement point of face width is the regulation requirement at the following 14 millimeters places of rail tread thereby satisfied vertical survey point.Measurement mechanism is measured the pit gauge (2) of circular hole (7) for being contained in vertical survey circular hole (6) and side respectively, and pit gauge (2) adopts stationary fit to be connected by fixed sleeving (4) and positioning reference framework (1).Auxiliary positioning screw (3) is made up of spring (11) that compresses plug (10), diastole state and locating pin (12).When measuring rail wear, the spring of diastole state (11) compression makes auxiliary positioning screw (3) be close to rail level, thereby plays the effect of auxiliary positioning.
The utility model compared with prior art has simple in structure, and measurement data is directly perceived, and upper track and following road are rapid, operator safety, and it is in light weight, carries conveniently.
The utility model has following accompanying drawing
Fig. 1, this measurement of rail wear based instrument wiring layout
Fig. 2, this measurement of rail wear based instrument positioning reference gimbal axis mapping
Fig. 3, this measurement of rail wear based instrument auxiliary positioning bolt structure figure
Among the figure: 1 benchmark positioning framework, 2 pit gauges, 3 auxiliary positioning screws, 4 fixed sleevings, 5 fixed step circular holes, 6 vertical survey circular holes, circular hole is measured in 7 sides, 8 locating surfaces, and 9 rail, 10 silk pressings are stifled, 11 springs, 12 locating pins, 13 movable chi, 14 ratchets, 15 detents, 16 medial surfaces, 17 microdrums surveyed.
Locating pin (12), the spring of diastole state (11) and compress plug (10) and be contained in respectively in the fixed step circular hole (5), compress plug (10) and benchmark positioning framework (1) by being threaded, fixed sleeving (4) is contained in vertical survey circular hole (6) and the side is measured in the circular hole (7), pit gauge (2) is contained in the fixed sleeving (4), pit gauge (2) adopts stationary fit to be connected by fixed sleeving (4) and benchmark positioning framework (1), benchmark positioning framework (1) adopts the aluminum alloy materials casting after the processing of retrofit baking vanish forms, and pit gauge (2) is surveyed chi (13) by activity, ratchet (14), detent (15) and microdrum (17) are formed.
The measurement of rail wear based process: holding measuring instrument during measurement, to be located the jaw portion of face (8) and rail (9) closely connected, medial surface (16) is closely connected with the web of the rail of rail (9), adjusting auxiliary positioning screw (3) makes locating pin (12) be close to rail (9) rail head tread or side, adjust adjustable rule (13), send sound up to ratchet (14), locking detent (15), the movable numeral of surveying on the chi (13) is abrasion of rail vertical plane or side wear, and it is accurate that it measures numerical value.
Claims (2)
1, a kind of measurement of rail wear based instrument, be used to measure the vertical abrasion and the side wear of railway operation circuit rail, comprise locating device and measurement mechanism, it is characterized in that locating device is the auxiliary positioning screw (3) in benchmark positioning framework (1) and the fixed step circular hole (5) that is contained in benchmark positioning framework (1), vertical survey circular hole (6) axis of benchmark positioning framework (1) is 1/3 of a rail head face width apart from rail (9) standard action edge, circular hole (7) axis is measured apart from 14 millimeters of rail (9) treads in the side, locating surface (8) is closely connected with rail (9) jaw portion, measurement mechanism is measured the pit gauge (2) of circular hole (7) for being contained in vertical survey circular hole (6) and side respectively, and pit gauge (2) adopts stationary fit to be connected by fixed cover (4) and benchmark positioning framework (1).
2, measurement of rail wear based instrument according to claim 1 is characterized in that auxiliary positioning screw (3) by compressing plug (10), and spring of diastole state (11) and locating pin (12) are formed.
