Description
Technical field
The present invention relates to a kind of calibration of laser range finder more particularly to the calibrations of hand-held laser rangefinder.
Background technology
Rangefinder is a kind of using laser as carrier wave, with the characteristics of target surface diffusing reflection measurement, passes through impulse method, phase method
The methods of measure space short distance distance Portable metering utensil.It is widely used in building construction measurement, crane deformation is surveyed
Amount, House property survey and mapping etc..Its error of indication directly affects construction quality, equipment safety, clearing justice etc..At present,
The method of calibration hand-held laser rangefinder is to be carried out using standard steel tape as standard on detecting platform, due to detecting platform
Horizontally disposed, just exemplified by calibrating the upper limit as the detecting platform of 50M, it is maximum the shortcomings that be：（1）Detecting platform will have
The length of more than 50M, general laboratory are difficult to have so long place to place the platform；（2）Standard steel tape is at this
Its levelness and straightness are difficult to ensure that in long span.（3）By the requirement of vertification regulation,（0~50）M scope internal calibrations
Point is no less than 10 points, if this requires detecting platform can also in the case where ensuring the preceding dike of standard steel tape levelness and straightness
Mobile, this undoubtedly adds the high cost of detecting platform.
The content of the invention
Detecting platform takes up an area the shortcomings that big, of high cost, error is big during in order to which laser range finder being overcome to calibrate, and the present invention provides
A kind of new way using vertical calibration laser range finder, the calibrating installation be not take up laboratory place and calibrating installation into
This is low, precision is high, easy to use.
The present invention is equipped with to calibrate the standard steel tape of the laser range finder error of indication, it is ensured that standard steel tape verticality
Lift heavy hammer and laser reflection plate, position laser range finder ranging reference block, install standard steel tape steel tape branch
Frame, extension arm, main body rack.
Specific technical solution is used by the present invention solves its technical problem：Extension arm is fixed on main body rack,
Standard steel tape is installed on steel tape stent, and steel tape stent is fixed on plane on the middle part of extension arm, and ranging reference block is consolidated
Due to the side of extension arm, the zero-bit of the positive alignment criteria steel tape of laser reflection plate is clamped in the tape of standard steel tape
On, lift heavy hammer is hung on the draw ring on tape head of standard steel tape, and the tape for mixing up measurement point is fixed on by tape gripping block
On ranging reference block, when calibrating each calibration point of laser range finder, it will be close to by school laser range finder bottom in ranging reference block
On, its laser launched is made to be mapped to the indicating value measured on laser reflection plate and is made comparisons with the standard value of tape measurement point,
It obtains by the error of indication of the school laser range finder calibration point, it is achieved thereby that the calibration to laser range finder.
The beneficial effects of the invention are as follows provide a kind of calibrating installation with vertical mode calibration hand-held laser rangefinder.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the application overall plan front view of the embodiment of the present invention.
Fig. 2 is the left view of Fig. 1.
Specific embodiment
In Fig. 1, main body rack 9 is placed in the pedestrian stairway top layer of skyscraper, and the fixation of extension arm 7 is locked at main body rack 9
On, standard steel tape 3 is installed in steel tape stent 8, and steel tape stent 8 is fixed on plane on the middle part of extension arm 7, ranging base
Quasi- block 6 fixes the side for locking onto extension arm 7, and lift heavy hammer 1 is hung on the draw ring on tape head of standard steel tape 3, makes mark
The tape of quasi- steel tape 3 in stair vacancy vertically downward, the zero-bit of the positive alignment criteria steel tape 3 of laser reflection plate 2
It is clamped in the tape of standard steel tape 3.In Fig. 2, tape gripping block 5 consolidates the tape for the standard steel tape 3 for mixing up measurement point
It is scheduled on ranging reference block 6, when calibrating each calibration point of laser range finder 4, will be respectively close to by 4 bottom of school laser range finder
On the measurement datum of the left and right sides of ranging reference block 6, its laser launched is made to be mapped to the left and right sides of laser reflection plate 2 just
On face, the average value of indicating value that left and right measures twice is made comparisons with the tape measurement point standard value of standard steel tape 3, is obtained
By school laser range finder 4 the calibration point the error of indication, it is achieved thereby that the calibration to laser range finder 4.
