Abstract
The utility model belongs to the technical field of railway measurement, and particularly relates to a track gauge measuring device of a railway track detecting instrument. The present railway track detecting instrument adopts the track gauge measuring structure of a track gauge sensor, and as the track gauge needs to be compensated at the section with smaller radius of curve, the measurement is insufficiently real and reliable. According to the utility model, a left guideway and a right guideway are arranged on the two sides of a measuring ruler, a left displacement sensor and a right displacement sensor are arranged between the two guideways, and the guideways and the displacement sensors are connected through spring connecting shafts. By adopting the double-sensor track gauge measuring structure, the track gauge measuring device dispenses with compensation, and has stable structure and real and reliable measurement result.
Description
Technical field
The utility model belongs to the railroad survey technical field, is specifically related to a kind of railroad track detector gauge measurement mechanism.
Background technology
In railway track construction and maintenance work, thereby need to adopt track detector that how much states in line track inside and outside are carried out the full geometric parameter that track is obtained in precision measurement usually, instruct the adjustment of orbital position on this basis.Gauge is one of important parameter of track geometry status, and the quality of gauge measuring accuracy will produce directly influence to non-fragment orbit construction of railways and maintenance.The existing track detector gauge measurement structure that adopt a track gauge sensor need compensate processing to gauge in the less location of sweep more, and the authenticity of measurement and reliability are not enough.
Summary of the invention
The purpose of the utility model provides a kind of railroad track detector gauge measurement mechanism that need not to compensate processing and guarantee to measure authenticity and reliability.
The technical scheme that the utility model adopted is:
A kind of railroad track detector gauge measurement mechanism is provided with the measurement ruler, it is characterized in that:
Described measurement ruler both sides are provided with left rail and right guide rail respectively;
Left dislocation sensor and right displacement transducer are set between left rail and the right guide rail;
Left rail is connected through the left spring coupling shaft with the left dislocation sensor, and right guide rail is connected through right spring coupling shaft with right displacement transducer;
Left rail is provided with left measuring wheel, and right guide rail is provided with right measuring wheel.
Described left rail, right guide rail, left dislocation sensor and right displacement transducer are fixed on through compressing tablet and screw and measure on the ruler.
The utlity model has following advantage:
The utility model has adopted the gauge measurement structure of dual sensor, need not compensate processing, Stability Analysis of Structures, and measurement result is true and reliable.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Among the figure, 1-measures ruler, 2-left side measuring wheel, the right measuring wheel of 3-, 4-left rail, the right guide rail of 5-, the right spring coupling shaft of 6-, 7-left spring coupling shaft, 8-compressing tablet, 9-left dislocation sensor, the right displacement transducer of 10-.
Embodiment
Below in conjunction with embodiment the utility model is carried out detailed explanation.
The described a kind of railroad track detector gauge measurement mechanism of the utility model is provided with left rail 4 and right guide rail 5 respectively in the both sides of measuring ruler 1; Left dislocation sensor 9 and right displacement transducer 10 are set between left rail 4 and the right guide rail 5; Left rail 4 is connected through left spring coupling shaft 8 with left dislocation sensor 9, and right guide rail 5 is connected through right spring coupling shaft 6 with right displacement transducer 10.Left rail 4 is provided with left measuring wheel 2, and right guide rail 5 is provided with right measuring wheel 3.Left rail 4, right guide rail 5, left dislocation sensor 9 and right displacement transducer 10 are fixed on through compressing tablet 8 and screw and measure on the ruler 1.Left side measuring wheel 2 moves on track to be measured with right measuring wheel 3; During measurement; When gauge changes; The position of left measuring wheel 2 of interlock influence and right measuring wheel 3 is changed along left rail 4, right guide rail 5 directions, and the transmission through left spring coupling shaft 8 and right spring coupling shaft 6 drives left dislocation sensor 9 and changes with right displacement transducer 10, thereby measures the variable quantity of gauge; Attenuating need not to compensate processing in the measuring error of the less location of orbital curve radius single-sensor gauge measurement mechanism.
