Abstract
The utility model discloses a three-point-form track irregularity measuring device which comprises a power supply system and a data acquisition and analysis system, as well as a measure installing bracket and measure sensors which are connected with the power supply system and the data acquisition and analysis system, wherein the measure installing bracket is provided with a plurality of measuring points, and each measuring point is equipped with a measure sensor. The three-point-form track irregularity measuring device has flexible measuring way and high measuring accuracy, and is simple in structure and convenient in maintenance; and the damage to a track by the measuring mechanism can be reduced furthest on the basis of completing measurement, and the measuring structure is simple and the reliable; therefore, convenience is brought to the track irregularity measuring operation.
Description
Technical field
The utility model relates to a kind of bikini track irregularity measurement mechanism, is applicable to the measurement of railroad track irregularity and magnetic-levitation irregularity.
Background technology
The detection of China railways track irregularity is development to some extent in recent years, but all be the development and the extension of external measurement mechanism basically, the measuring mechanism complexity, adopt the mode of contact type measurement on the method for measurement, therefore the measured error of being introduced by the measuring mechanism wearing and tearing is to be difficult to prediction and elimination, and measuring mechanism also can cause certain damage to track in measurement process simultaneously.This is difficult to satisfy the requirement to the track ride comfort in operational process of High Speed Train in China and magnetic suspension train to these factors to a certain extent.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and provides that a kind of systematic error is little, survey precision is high, and is simple in structure, is convenient to safeguard, to the little bikini track irregularity measurement mechanism of track damage.
The utility model is achieved through the following technical solutions: comprise electric power system and data acquisition and analysis system, comprise measure erecting frame, with described electric power system and data acquisition and analysis system bonded assembly survey sensor, described measurement erecting frame is provided with a plurality of measurement points, on each described measurement point survey sensor is installed.
In the utility model, described electric power system is contained in to be measured on the erecting frame or external and be connected power supply with described sensor with described data acquisition and analysis system by cable.
In the utility model, described measurement erecting frame is provided with first measurement point, second measurement point, the 3rd measurement point, and described first measurement point, second measurement point, the equidistant arrangement of the 3rd measurement point are in line.
Adopt said structure, the utility model metering system is motor-driven, flexible, and the survey precision height is simple in structure, easy to maintenance; Reduced because the not high systematic error of introducing of physical construction reference for installation reliability; Can reduce the infringement of measuring mechanism on the based measurement to the full extent finishing to track, measure simple in structure, reliable simultaneously, for the measurement of track irregularity brings convenience, and the measurement of orbit geometry parameter is by the realization that cooperatively interacts of survey sensor and data acquisition and analysis system, orbit geometry parameter after the measurement finally is stored in the main control computer, for the maintenance of track provides foundation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model continuous gauging data acquisition scheme drawing.
In the accompanying drawing 1,2,1---first measurement point, 2---second measurement point, 3---the 3rd measurement point, 4---measures erecting frame, the tested orbital plane of 5---.

With reference to Fig. 1, present embodiment comprises first measurement point 1, second measurement point 2, the 3rd measurement point 3, survey sensor is measured erecting frame 4, and the distance between two measurement points that close on is all L mutually, survey sensor is installed on described first, second, third measurement point 1,2,3 of measuring erecting frame 4, and the utility model also comprises electric power system and data acquisition and analysis system.Described electric power system provides the power supply of survey sensor and data acquisition and analysis system.Described data acquisition and analysis system comprises data acquisition system and main control computer, data processing system links to each other with survey sensor with electric power system by shielded cable or transmission over radio, main control computer links to each other with data acquisition system by shielded cable or transmission over radio, and main control computer can adopt peripheral hardware computing machine or the palm PC of measuring software for calculation is installed.
With reference to Fig. 2, this device is measured apart from the track tested surface long continuously, and obtain the track irregularity geometric parameter of each time, and can analyze, handle measured data by the take off data analysis software at last, draw the track irregularity numerical value of 10m and 20m string.Described first measurement point, 1, the second measurement point, 2, the three measurement points 3 provide the measurement to tested orbital plane 5; Described measurement erecting frame 4 provides the reference for installation of three measurement points, guarantees measuring reliability; Described survey sensor provides precision higher take off data;
This device comprises the track height to the measurement of track irregularity, and rail is to isoparametric measurement.
During measurement, this device is realized the measurement of orbit parameter by the distance between three measurement point continuous gauging tracks and the measurement point, measure the back survey sensor data that record are sent into main control computer through data acquisition system, main control computer is handled data, take off data to each position is carried out numerical calculation, draws the track irregularity numerical value of this position; Measuring mechanism continuous gauging multi-group data, and the take off data of every group of track irregularity is analyzed, calculated by main control computer, calculate the track irregularity numerical value of 10 meters on track and 20 Mi Xian etc. at last by Survey Software, and each result of a measurement and track irregularity numerical value stored in the main control computer automatically, and on the screen of main control computer, show in real time.
Can be orbit construction and maintenance provides foundation by the measured track irregularity geometric parameter of bikini track irregularity measurement mechanism.
