Background technique
When track switch offset distance, the detection of opening value class corner, with rail top of steel rail for vertical positioning surface, located lateral point is gauge line
Position (the rail head lateral location at theoretical rail top decline 16mm).Traditional measurement method generally uses steel tape, clamp and steel plate
Ruler, general vernier scale etc. measure, and gauge line position visually judges by personnel, and the horizontality of measuring tool is not easy
Determine, there is the deviation of about 0~3mm, detection error can account for the 0~40% of offset distance tolerance, in addition steel tape, Steel Ruler etc.
Accuracy of reading itself only has 0.5mm, and detecting accumulative measurement error even can account for the 100% of tolerance, and precision is difficult to ensure.Portion
The gauge line that quartile is set must rely on palpus because (such as opening value at tongue, long the first towing point of heart rail) may be not present in processing
Extended surface measures, so that the measurement error of traditional measurement tool and method is bigger.On the other hand, the offset distance of different location or
Opening, is influenced by railway turnout rail part structure and rigging position, is needed with different general gage measurings, in addition track switch assembling process
In also to measure other corners such as flangeway width, rail height, rail surface profile, limiter gap deviation, lead to measurer
Type is more, inconvenient to carry.

The left side of measuring claw is bonded with the left side confined planes of limiter B, and on main scale the upper side of measuring claw and limiter B top surface
Fitting；The left limit face paste of subsequent moving cursor, the left side and limiter A that make vernier pair Russia measuring claw is closed；Blade is read at this time
Number scale is m；By same procedure measure the right side confined planes of limiter B to limiter A left side confined planes distance value, be denoted as n,
Then m-n is measurement data.
G, guard rail flangeway width measures；
Firstly, moving cursor, it is located at guard rail on main scale on measuring claw and vernier between measuring claw, while measuring claw position on vernier
Between rail and guard rail.Then, it is bonded measuring claw right side on main scale with guard rail inoperative side；Last moving cursor, makes
Ruler frame upper surface is bonded with rail surface, and third measuring surface bottom edge is located at rail gauge line position, and is bonded with rail side；This
When blade reading be denoted as k plus the vertical width of measuring claw on vernier；Last moving cursor makes measuring claw left side on vernier
It is bonded with guard rail work flank side surface, the reading of blade is denoted as t at this time, then k-t is measurement data volume volume；
H, tongue profile matching measurement；
Firstly, leaning on the left end benchmark curved surface of ruler head with tongue rail topstick, keep contact range internal clearance whole minimum, range estimation judgement
Or whether it is greater than 0.2mm with the gap width of patch detection tongue and benchmark curved face contact range, it is unqualified if more than then profile.
3. a kind of track switch assembled multifunctional offset distance measuring scale as described in claim 1, it is characterised in that: ruler head and ruler frame up and down
Side horizontal face length range is 25~71mm.
4. a kind of track switch assembled multifunctional offset distance measuring scale as described in claim 1, it is characterised in that: be provided in the main body of vernier
Screw hole, for being threadedly coupled lock-screw；Blade end is equipped with limit screw.
