Description
Technical field
The present invention relates to a kind of road section measuring instrument, belong to the road surface fields of measurement.
Background technology
The road section measuring instrument is the instrument that is used to measure road surface or building section geometry.What present known road section measuring instrument adopted is the method for mechanical measurement, instrument includes wooden double guide rail, chain is housed on the guide rail, guide rail is connected by chain with support, drive unit is arranged on the support, there is the roller probe support lower end, be fixed with pen on the support, the method of measuring is that drive unit drive support moves on the chain of wooden double guide rail, the roller that drive is connected on the support slides on section, allow be connected the parallel track that stroke on the support goes out probe movement, then track is analyzed, pen is drawn the section geometric figure.The shortcoming of this instrument is:
1. there are a lot of coarse reasons in mechanical measurement, owing to be the roller of usefulness, has a lot of road surfaces might occur causing and can not accurately measuring than the littler hole of roller diameter; Owing to be contact measurement, the material of section also there is requirement, can not adapt to all section situations.
2. may there be coarse place in mechanical drawing, and precision is not high.
3. the conditional request of Ce Lianging is also than higher, to the requirement of paper and pen also than higher.
The time of measuring process also long, need to analyze plurality of processes such as drawing through measuring.
5. because the assembling of things such as wooden guide rail and chain and pen, paper, probe and transportation are not light, cause instrument to move inconvenience.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides that a kind of certainty of measurement height, signal are handled easily, the measuring condition requirement is low, Measuring Time is short, the road section measuring instrument of conveniently moving.
Technical scheme provided by the invention is: a kind of road section measuring instrument comprises a guide rail; The rail brackets of the described guide rail of one supporting; One is installed on the described guide rail and along it and makes the drive unit of straight reciprocating motion; Described drive unit comprises power-equipment, transmission mechanism, support, road wheel; Be installed in the displacement transducer on the described support: comprise lateral displacement sensor, length travel sensor; Be installed on the guide rail and make drive unit change the pole changer of the direction of motion, the guide rail two ends are provided with the pole changer baffle plate; It is characterized in that: described displacement transducer is a non-contact displacement transducer;
The invention has the beneficial effects as follows: is data signal through lateral displacement sensor and length travel sensor transmissions to the signal of exporting to the PC end behind the terminal board, easier processing, take non-contact measurement displacement meeting more accurate, measuring process is brief, measures simple.
Further, consider the problem of certainty of measurement, described length travel sensor is a laser displacement sensor.
Use the beneficial effect of laser displacement sensor to be: the precision of laser measurement is at 0.00005m, and far above the section survey required precision 0.005-0.001m of national regulation, and laser measurement is non-cpntact measurement, and antijamming capability is strong, and adaptive surface is wider.
Further, consider problems such as Costco Wholesale, certainty of measurement, described lateral displacement sensor is a rotary encoder.
Further, consider the selection problem of guide rail, for problem such as more light, level, frictional force is even, described guide rail is a shaped steel.
Use the beneficial effect of shaped steel to be: the mechanical property of shaped steel is good, and assembling and transportation are all simpler, has reached the effect of conveniently moving.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
In Fig. 1, present embodiment is provided with laser displacement sensor 1, laser displacement sensor 1 is fixed on support 11 bottoms, guide rail 5 is connected with driven pulley 10 by driving wheel 7 with stepper motor 9 with stepper motor driver 8, laser displacement sensor 1, rotary encoder 6, stepper motor driver 8, stepper motor 9 are connected with terminal board 2 respectively, terminal board 2 is connected with power supply 3, and guide rail 5 two ends are provided with pole changer baffle plate piece 12.
The present invention in use, by laser displacement sensor 1, support 11, stepper motor driver 8, stepper motor winding 9, rotary encoder 6, driving wheel 7, driven pulley 10, it is slidably whole reciprocating that pole changer 4 is formed, after each one way stroke finishes, touch pole changer 4, pole changer 4 triggers rotary encoder 6, rotary encoder 6 imports pulse signal into and enters stepper motor driver 8, stepper motor driver 8 control step motor windings 9 drive driving wheels 7 allow slidably, and integral body moves reciprocatingly once more, because laser displacement sensor 1 uniform speed scanning section in the motion, determine the abscissa of laser length travel sensor scan content by rotary encoder 6, the scans content of laser displacement sensor 1 is determined ordinate, and signal inserts the PC end by terminal board 2.
Adopt this method, the precision height of measurement, and certainty of measurement height, signal are handled easily, the measuring condition requirement is low, conveniently move, bottom profiler that Measuring Time is short.
Above-described only is preferred implementation of the present invention, should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, such as:
1. driven disc sharpener is spent and increased the precision that frictional force keeps horizontal reciprocating movement;
2. the conversion laser displacement sensor is the sound wave displacement transducer;
3. the conversion rotary encoder is the acceleration displacement transducer, and 2 integrations by acceleration obtain the method for displacement and determine abscissa;
4. the conversion rotary encoder is horizontal laser displacement sensor, directly measures displacement and determines abscissa.
These also should be considered as protection scope of the present invention, and these can not influence effect of the invention process and practical applicability.
