Description
Technical field
The present invention relates to railroad engineering survey technical field, specifically a kind of anti-lost track row range unit.
Background technique
Railroad engineering survey is the measurement work of the prospecting for railway engineering, design, construction and operation management etc. and progress.
Railroad engineering survey is one of most basic, most critical link in railway engineering, particularly important.
Traditional measurement pattern mostly uses tape measure or rail row stadia surveying, wherein due to not in tape measure mode
With producer production the different material of tape measure precision it is different cause dilatability different, the strength size of measuring tape in measurement process
No small influence can be generated on measurement result, and can be elongated by repeatedly pullling ruler, reading is just inaccurate.Secondly it is artificial because
Element participates in excessively, and measuring common ordinary tape measure is mostly 50 meters or 100 meters, and rising and falling and read all for each ruler can exist artificially
Error, each track section 600-1000 meters of section are differed, and need multiple cyclic advance that could complete, after multiple error accumulation
Obtained data very likely transfinite with actual range than just.
Though rail row rangefinder can be counted with continuous walking, it is affected by human factors also quite large, walks and holds on rail
It is curved easily to walk S, is easy to fall down, if lower surging is too small it is also possible that the case where rolling, these situations can all influence ranging
Instrument meter number, error in reading is bigger when rail gap or Cha Qu jolt excessively.
Separately there is the invention of Publication No. 201720104025.5, it discloses a kind of wheeled rail length-measuring appliances, lead to
One group of measuring wheel being stuck on steel rail web is crossed to carry out to rail measurement of length, which may be only available for the rail of straight trip,
If encountering rail gap or Cha Qu jolting, device is difficult to pass through, and the number that the measuring wheel of the left and right sides is measured in non-straight trip orbital segment
According to disunity, error in reading is larger.
