Abstract
The invention relates to a vernier caliper for steel rail offset distance measurement and a measuring method thereof, which can accurately measure a steel rail offset distance in a city rail transit. A main ruler is a cross structure; a ruler frame is T-shaped; the main ruler is embedded by a main ruler vernier; the ruler frame is assembled on the main ruler; and a fastening screw is fastened on the ruler frame. The invention has the advantages that: the vernier caliper for steel rail offset distance measurement and the measuring method thereof are applicable to most turnout products of the city rail transit, are simple and convenient in operation and low in inspection cost, can also carry out a variety of types of measurement, and are suitable to be used in the rail production and installation and other places.
Description
Technical field
The present invention relates to a kind of rail offset distance that can accurately measure urban track traffic rail offset distance and measure by vernier caliper and measuring method, belong to special vernier caliper and manufacture field.
Background technology
CN2745024Y, title " railway offset scale ", it includes blade and scale, it is characterized in that this offset scale blade is duplexing shape profile structure, section bar is the rectangular tube that extend with horizontal outer on upper and lower both sides, the inner side on top outer extension both sides forward has notch, corrosion resistant plate with scale is put into along notch, be set in offset scale above, in its outer end to fix with the pin protruding, blade inner end is vertically fixed with four-bladed vane, below four-bladed vane, be fixed with gauge head, the trip frame that slides is housed in the middle of blade, blade, scale and trip frame are fitted together distance measuring equipment in aggregates.In this patent documentation, relate to rail offset scale structure, rail top surface structure, range, detection mode, offset scale error of indication measurement etc., all different from teachings herein.
At present, the domestic track switch product for urban track traffic, in the machining dimension testing process to its Rail part, existing test measuring device adaptability is poor, inefficiency, the quality of product can not get effective control.The offset distance on traditional detection rail top of steel rail decline 16mm line place's working edge or inoperative limit is mainly used tape measure, thereby whether align and reach the object of measurement by range estimation datum line, its stability, accuracy are all unreliable, therefore, non-standard, special, the special measuring testing tool of Optimizing Reconstruction is of great significance improving the machining quality tool of rail.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design a kind of rail offset distance of measuring rail top of steel rail decline 16mm line place's working edge offset distance or inoperative limit offset distance and measure by vernier caliper and measuring method.
Design proposal: in order to realize above-mentioned purpose of design.The present invention, in structural design, comprises a main scale, a chi frame, main scale vernier, trip bolt in survey instrument structural design.Main scale across shape, chi frame is shaped as T-shaped, take main scale transverse bar as main scale vernier zero graduation line starting point; During measurement, the main scale of this chi is ridden over to top surface of rail, main scale is fitted in rail head of rail, and attachable mechanical stage frame is fitted in another rail head of rail simultaneously, just can measure rail offset distance.When the present invention uses, can measure gage line at homonymy, or two working edges are at heteropleural, also can measure in the inoperative limit of homonymy or heteropleural offset distance.
Technical scheme 1: a kind of rail offset distance measurement vernier caliper, main scale across structure, chi frame is shaped as T-shaped, embeds main scale vernier on main scale, and chi frame is assemblied on main scale, and trip bolt is screwed on chi frame.
Technical scheme 2: a kind of rail offset distance is measured the measuring method with vernier caliper, and main scale rides on rail head of rail, and chi pawl leans against working edge place, it is tread decline 16mm line place, chi is frameed shift to another rail homonymy rail head and is adjacent to, and finally tightens trip bolt, just can detect the rail offset distance of homonymy; Or main scale rides on rail head of rail, chi pawl leans against working edge place, i.e. tread decline 16mm line place, and chi is frameed shift to another rail heteropleural rail head and is adjacent to, and finally tightens trip bolt, just can detect the rail offset distance of heteropleural.
The present invention compares with background technology, is not only applicable to the measurement of most of track switch products such as urban track traffic, and simple to operation, and inspection cost is low, can carry out multiple measurement simultaneously, is applicable to the place such as production, laying of track.
Accompanying drawing explanation
Fig. 1 is that rail offset distance is measured the structural representation with vernier caliper.
Fig. 2 is that rail offset distance is measured the example schematic of measuring with vernier caliper homonymy.
Fig. 3 is that rail offset distance is measured the example schematic of measuring with vernier caliper heteropleural.
