The present invention adopts following technical scheme to realize:
High-speed railway CRTS II type track plate support rail platform multifunctional measuring locating rack; It is characterized in that being made up of a connecting screw rod and two location gauge heads, connecting screw rod two ends car has screw thread, and wherein threaded one end is a left-hand thread (LHT); One end is a right-hand thread, so that finely tune the spacing between the two location gauge heads.The location gauge head is that a block member and its longitudinal section are right-angled trapezium; The thickness of location gauge head is that the measurement point of support rail vice jaw distance of design code is apart from the vertical height of support rail face; The domatic gradient in outer end of location gauge head meets the gradient of the vice jaw surface of support rail platform, is drilled with above the gauge head of location to be used to accept the most advanced and sophisticated positioning round orifice in levelling pole base bottom.
The present invention has following beneficial effect:
1, solved the problem of track plate support rail vice jaw range observation, for length-measuring appliance provides measurement point position accurately to a difficulty.
2, solved the difficult problem that existing conventional instrument can't be measured the support rail platform rail cant gradient; Through the location gauge head with and positioning round orifice and the levelling pole base of going up ingenious setting match; Convert slope measuring into the level precision measurement, not only convenient intuitively but also improved measuring accuracy.
3, solved the difficult problem of the row support rail anteklise high measurement that existing conventional instrument can't carry out, for the sagitta measurement provides accurately point, not only convenient intuitively but also improved measuring accuracy.
4, adopting two ends is that right-and-left threaded screw rod connects the location gauge head, regulates the distance between the gauge head of location easily.
5, simple structure is made easily, can reach degree of precision, satisfies the rail support groove template and measures high-precision requirement.
6, realized multi-functionally, used same frock just can accomplish the measurement of support rail platform many index (jaw distance, the rail cant gradient and sagitta), and be not only applicable to production board, also be applicable to blank flat.
7, novel, use simple member designs, just solved a complicated technology difficult problem.And it is convenient directly perceived.
8, cost of manufacture is low, and the alternative measuring appliance that needs the costliness of import has been practiced thrift substantial contribution.
9, high-speed railway is in the ascendant, and track plate field will be built in a large number, so track plate surveying work amount is very big.So this measurement frock has very broad prospect for its application.
