In figure mark for：
1st, laser range finder；2nd, plate body；3rd, line falls.
Embodiment
In order to make it easy to understand, the utility model will be further described below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of schematic diagram of the range unit provided for the utility model embodiment.
The range unit that the utility model embodiment provides includes laser range finder 1, plate body 2 and line pendant 3.
Wherein, it is provided with protractor on plate body 2；
Laser range finder 1 is fixedly connected with plate body 2, the datum mark of laser range finder 1 overlapped with the central point of protractor or
The line of the central point of person and protractor is perpendicular to the plane where protractor, and the laser beam of laser range finder 1 is parallel to amount
Plane where the device of angle；
The messenger wire of line pendant 3 is overlapped with the fixed connection point of plate body 2 with the central point of protractor or the center with protractor
The line of point is perpendicular to the plane where protractor.
Referring to Fig. 2 and Fig. 3, the range unit provided for the utility model embodiment uses schematic diagram, to measure level
Exemplified by distance, during original state, laser range finder 1, which is located at, can make the horizontal state projected of laser beam, pass through the amount on plate body 2
Angle device can read the now angular readings corresponding to the messenger wire of line pendant 3.When having barrier between two measured points, line is fallen
Measuring point is pointed in 3 lower end, then by laser range finder 1 open alignment target point eminence point (point of the eminence and target point
Line is vertical direction), check the screen reading of laser range finder 1, and check plate body 2 protractor reach the standard grade pendant 3 messenger wire this
When corresponding angular readings, the angular readings are compared with the angular readings corresponding to the messenger wire of line pendant 3 during original state
The angle that plate body 2 turns over, the i.e. angle of the laser beam of laser range finder 1 and horizontal plane can be drawn, can with cosine formula
Know, the cosine value of above-mentioned angle is equal to the quotient of the reading of two measured point horizontal ranges divided by laser range finder 1, therefore, passes through
Calculating can draw the horizontal range between two measured points.
Understandable to be, the sine value of the angle turned over using plate body 2, range unit provided by the utility model may be used also
To measure the vertical distance (i.e. difference in height) between two measured points.
In range unit provided by the utility model, laser range finder 1, protractor and line pendant 3 are provided with plate body 2, by
Overlapped in the datum mark of laser range finder 1 with the central point of protractor or with the line of the central point of protractor perpendicular to angulation
Plane where device, line pendant 3 messenger wire overlapped with the fixed connection point of plate body 2 with the central point of protractor or with protractor
The line of central point is perpendicular to the plane where protractor, and the laser beam of laser range finder 1 is parallel to where protractor
Plane, so, when plate body 2 rotates in the plane where protractor around the central point of protractor, pass through the messenger wire of line pendant 3
The angle (angle that namely laser range finder 1 turns over) that plate body 2 turns over can be read with protractor, laser range finder 1 then may be used
To measure air line distance between the central point of protractor and measured point (or subsidiary point), by above-mentioned air line distance with being tested
Geometrical relationship and trigonometric function knowledge between distance, tested distance can be calculated indirectly with reference to the angle that plate body 2 turns over.
During due to there is barrier between measuring point and target point, range unit provided by the utility model can pass through selection
The measured point (or subsidiary point) of avoiding obstacles draws the distance between measuring point and target point indirectly, so, the ranging
Device can adapt to the complex situations of job site, be advantageous to improve operating efficiency of the worker across barrier ranging.In addition, the survey
Good away from device portability, operation is also very simple.
As shown in figure 1, in the present embodiment, the central point of protractor and the line of zero graduation are perpendicular to laser range finder 1
The fan dial of laser beam, i.e. protractor is using centre position as zero graduation, so when measuring 2 points of horizontal range,
The angle turned over of plate body 2 can easily be read.
In the present embodiment, plate body 2 uses isosceles right angle triangle, and the laser beam of laser range finder 1 is parallel to plate body 2
Hypotenuse.Certainly, plate body 2 can also use other shapes.The material of plate body 2 can be steel plate or plank.
For the ease of calibrating the position of protractor, in the present embodiment, when projection of the messenger wire on plate body 2 of line pendant 3 is passed through
During the zero graduation of protractor, projection by plate body 2 right-angled apices, so, before measuring can by line fall 3 messenger wire and
The right-angled apices of plate body 2 calibrate the dial position of protractor.
In measurement process, in order to which the horizontal range between 2 points is calculated, it is necessary to calculate more than the angle that plate body 2 turns over
String value, calculated in order to facilitate worker, scientific calculator can be installed on plate body 2.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or new using this practicality
Type.A variety of modifications to embodiment will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments in the case where not departing from spirit or scope of the present utility model.Therefore, originally
Utility model is not intended to be limited to embodiment illustrated herein, and is to fit to and principles disclosed herein and features of novelty
