Abstract
The utility model relates to a rail fractured surface measurer used for measuring the shape of a rail fractured surface. The utility model is composed of a support seat, a profiling mechanism, a drawing pen, a drawing bow, a drawing board, etc., wherein, the drawing pen and the drawing bow are respectively installed on the upper and the lower ends of a main bar of the profiling mechanism. The top end of the drawing bow is provided with a rotary wheel. The rail fractured surface measurer has the characteristics of simple structure, proper dimension, light weight, high measuring precision, convenient operation, high speed, etc.
Description
The utility model relates to a kind of surveying instrument that is used to measure the rail profile shape.
Domestic past attempts was developed the rail profile measuring instrument that adopts the profiling principle, but all because of unreasonable structure, the unreasonable structure of tracing bow particularly, and can not guarantee the precision measured, and use also inconveniently, thereby fail to be applied.
The purpose of this utility model provide a kind of rational in infrastructure, measuring accuracy is high, rail profile measuring instrument easy to use.
The purpose of this utility model is achieved in that
Constitute the utility model by bearing, feeler mechanism shell, feeler mechanism, ruling pen, tracing bow and plotting sheet.The feeler mechanism shell is installed on the bearing, bearing is made by magnetic material, feeler mechanism is installed in the feeler mechanism shell, adopt precise miniature bearing to connect between each rod member of feeler mechanism, ruling pen is equipped with in feeler mechanism mobile jib upper end, the lower end links to each other with the tracing bow by rolling bearing, and tracing bow top is provided with roller, and plotting sheet is installed in the top of feeler mechanism shell.
The utlity model has following advantage:
1. rational in infrastructure, overall dimensions are little, and are in light weight.
2. measuring accuracy height, measuring accuracy reaches in the 0.2mm.
3. the employing bearing connects between tracing bow and the feeler mechanism mobile jib, and freely Rotate 180 ° can be measured the rail both sides easily.
4. tracing bow top is provided with roller, has solved the problem of measuring rail surface and rail jaw lower surface simultaneously, simultaneously, makes tracing more level and smooth.
5. the employing magnetic stand is easy for installation, and measuring speed is fast, measures a section and only needs one minute, has guaranteed being perfectly safe of driving and personnel.
Accompanying drawing is a structural representation of the present utility model.
Further narrate the utility model below in conjunction with accompanying drawing;
Feeler mechanism shell 1 is installed on the bearing 2, feeler mechanism 3 is installed in the feeler mechanism shell 1, and ruling pen 5 is equipped with in feeler mechanism mobile jib 4 upper ends, and the lower end links to each other with tracing bow 7 by rotation axis 6, tracing bow 7 tops are provided with roller 8, and plotting sheet 9 is installed in the top of feeler mechanism shell 1.
Claims (2)
1, a kind of rail profile measuring instrument, it is characterized in that: the feeler mechanism shell is installed on the bearing, feeler mechanism is installed on the feeler mechanism shell, adopt precise miniature bearing to connect between each rod member of feeler mechanism, ruling pen is equipped with in feeler mechanism mobile jib upper end, the lower end links to each other with the tracing bow by rolling bearing, and tracing bow top is provided with roller, and plotting sheet is installed in the top of feeler mechanism shell.
