Horizontal rate of change: claim again twist irregularity.The difference ratio long with base with the long horizontal survey value of 2.5m base.Actual how much irregularities of this project appraisal are height, and being uneven in the shorter scope of its key evaluation is suitable.Horizontal rate of change directly affects tilting of car body, and is stronger on the oscillation crosswise impact of car body, influential to travel safety and comfortableness.Space coordinates acquisition after main control computer is processed that in the utility model, gauge rate of change and horizontal rate of change are all ordered by obtaining space P.

The railroad track geometric shape detection method that the utility model provides comprises following step:

Step 1, use total powerstation utilize Along Railway known control point to establish station along the railway

Total powerstation is placed on the triangular base that sets up on railway line, carries out leveling work, make the total powerstation body be in level; And make the telescope crosshair of total powerstation aim at the prism center that is placed on known control point, measure, by the space coordinates and the total powerstation telescope axle azimuthal process of living in that calculate total powerstation body center present position apart from information such as angles of measuring gained, be called Setting Station of Total Station Instrument.

What Setting Station of Total Station Instrument used herein is that the station method is established in resection, and use total powerstation telescope crosshair to aim at and measure the prism of laying on a plurality of known points, use obtain apart from relevant informations such as angles, calculate space coordinates and the total powerstation telescope axle institute azimuthal of total powerstation body center position; The quantity that is arranged on the prism on known point that need to measure during measurement should not be less than 4, generally need to measure 8 control points on newly-built high-speed railway, obtain this moment apart from angle information more than calculating the needed master data of total powerstation body center locational space coordinate, we claim that unnecessary survey data is redundant observation, can use least square adjustment to calculate the optimal value of the space coordinates of total powerstation present position this moment, and we are referred to as measurement adjustment this process.

Above Setting Station of Total Station Instrument and measurement adjustment process can be used the airborne resection of total powerstation to establish the station program directly to use total powerstation to establish station and adjustment.Corresponding measuring method all belongs to known content, does not repeat them here.

Step 2, the utility model is placed on railway track

In order to ensure certainty of measurement, the track geometry form detector that the utility model provides is put in total powerstation, being on same rail line, and should be greater than 100m apart from the distance of total powerstation.

While putting, three horizontal wheels assemblies (two left side horizontal wheels assembly 1-3-02, right side horizontal wheels assembly 1-2-07) that should guarantee track geometry form detector all with the upper end face close contact of rail, and guarantee two left side spacing reference wheels of the present utility model (in the spacing reference wheel assembly 1-2-03 of left side) and two distance measurements wheel 6-02(left side spacing detecting unit 1-1-05 and right side spacing detecting unit 1-2-08) with rail medial surface close contact.

Prism is placed in prism table of the present utility model, and the glass dignity that makes prism is over against total powerstation.

Connect the utility model and main control computer: main control computer is arranged on computer bracket 11-03, the usage data line connects main control computer and the utility model, described left side spacing detecting unit 1-1-05, right side spacing detecting unit 1-2-08, height detecting unit 1-3-09 are connected and are connected main control computer with mileage detecting unit 1-1-06, guarantee that all the sensors data on the utility model can be transferred on main control computer, described main control computer can be chosen as notebook computer.

Step 3, total powerstation telescope central cross silk is aimed on of the present utility model the center of the prism of laying

Use main control computer remote control total powerstation to measure the center of the prism laid on the utility model, measure the 3 d space coordinate of the prism center of laying on the utility model, and will measure resulting coordinate data and radio to main control computer.

meanwhile, main control computer by data wire to sensors all on the utility model (i.e. left side spacing detecting unit 1-1-05, right side spacing detecting unit 1-2-08, height detecting unit 1-3-09 and mileage detecting unit 1-1-06) send and measure instruction, sensors all on order the utility model are measured (height detecting unit 1-3-09 measurement heeling condition of the present utility model to current status, left side spacing detecting unit 1-1-05, right side spacing detecting unit 1-2-08 measures rail spacing variable condition, mileage detecting unit 1-1-06 measures mileage), and use main control computer read sensor measurement result.

The position relationship of step 4, the spatial data according to the prism center of laying on the utility model, each sensor measurement the data obtained and the enorganic all parts of the utility model, use main control computer to calculate gauge, level (superelevation) numerical value of the residing rail of the utility model.

Step 5, the utility model is pushed forward a sleeper pitch (sleeper of rail below and the distance between sleeper) towards the direction of total powerstation along rail, return to step 3, repeated execution of steps 3 and step 4.

Step 6, when the utility model apart from the distance of total powerstation during less than 10m, stopping the utility model pushing no longer forward, total powerstation is packed up, (forward pitch is identical from the control point spacing that should lay with the railway periphery to push the direction reach to the utility model, the control point spacing of laying as the railway periphery is 60m/ couple, 60m moves forward), return to step 1, remeasure the data of next position.

After step 1 is completed, the utility model is pushed 10 sleeper pitches, repeating step 3, step 4, step 5 to the direction away from total powerstation along rail.

Step 7, after the rail measurement that needs are measured is completed, pack up the utility model, use main control computer to carry out data preparation to measuring the data obtained, and the rail that calculates rail according to survey data to, just, the data such as gauge rate of change, horizontal rate of change, and be organized into table, namely obtain Measurement results.The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited to this.Those skilled in the art do on the utility model basis be equal to substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
