Description
Technical field
The utility model is related to a kind of laser ranging systems, belong to construction equipment technology field.
Background technology
Laser range finder（Laser rangefinder）, be using modulate laser some parameter realize to target away from
Instrument from measurement.Laser range finder measurement range is 3.5 ~ 5000m.It is divided into ranging phase method instrument and arteries and veins according to distance measuring method
Method rangefinder is rushed, pulse type laser rangefinder is to project pulse laser beam a branch of or that a sequence is of short duration to target at work,
The laser beam of target reflection is received by photoelectric cell, timer measures laser beam from the time for being emitted to reception, calculates from sight
Survey person's range-to-go.When Phase Laser Range Finder is propagated in space using detection transmitting light and reflected light
Phase difference carrys out detecting distance.Light-weight, small, the easy to operate speed of laser range finder is fast and accurate, and error is only it
/ 5th of its optical rangefinder arrive the one of hundreds of points.What existing laser range finder measured is laser range finder to measured object
The distance between body, but two in range of vision can not then be surveyed with the distance between distant object of operating personnel
Amount.
Utility model content
Therefore, the purpose of this utility model is to provide a kind of laser ranging dresses that can measure distance between two objects
It puts.
To achieve these goals, a kind of laser ranging system of the utility model, including pedestal, is fixed on pedestal
Vertical bar, positioned at the universal joint on vertical bar top, the first laser rangefinder above the universal joint, positioned at first laser
The bearing of round angle scale and angle scale coaxial arrangement above rangefinder, the shaft being installed in the bearing, it is fixed
Second laser rangefinder in the shaft top is fixed on the shaft and the pointer on the angle scale upper surface；
The shaft can rotate in bearing, so as to which the second laser rangefinder and pointer be driven to rotate synchronously；The angle scale
Upper surface be provided with 360 ° of angle mark, when phase is directed toward in the measurement of the first laser rangefinder and second laser rangefinder
0 ° of position on the pointer orientation angle disk simultaneously.
The universal joint includes the steel ball positioned at the vertical bar top, is fixed on the first laser rangefinder lower face
Installation bowl, it is described installation bowl on be provided with several vertical straight slots, it is described installation bowl lower end be bolted with a clamp nut.
The width of the pointer has from one end that it is connected to one end of the shaft to the separate shaft gradually to be subtracted
Small trend.
Using above-mentioned technical proposal, the laser ranging system of the utility model, when use, rotates second laser rangefinder, makes
The distance that first rangefinder and the second rangefinder distinguish two objects under test of measurement distance is respectively S1 and S2, and measurement finishes postscript
The rotation angle for recording pointer is α, so as to which the distance between two objects under test can be calculated according to the cosine law.This practicality
Novel laser ranging system, compared with the prior art in laser range finder, have measure two objects under test between away from
From to construction or detection offer facility.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the vertical view of Fig. 1.

Specific embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the present embodiment provides a kind of laser ranging system, including pedestal 1, the vertical bar being fixed on pedestal 1
2nd, the universal joint 3 positioned at 2 top of vertical bar, the first laser rangefinder 4 above the universal joint 3, positioned at first laser
The round angle scale 5 of 4 top of rangefinder, the bearing 6 being coaxially disposed with the angle scale 5, the shaft being installed in the bearing 6
7, the second laser rangefinder 8 on 7 top of shaft is fixed on, is fixed on the shaft 7 and positioned at 5 upper surface of angle scale
On pointer 9；The shaft 7 can rotate in bearing 6, so as to drive the second laser rangefinder 8 is synchronous with pointer 9 to turn
It is dynamic；The upper surface of the angle scale 5 is provided with 360 ° of angle mark, when the first laser rangefinder 4 and second laser are surveyed
0 ° of position when the measurement of distance meter 8 is directed toward identical on the pointer orientation angle disk.
The universal joint 3 includes the steel ball 31 positioned at 2 top of vertical bar, is fixed on the first laser rangefinder 4
The installation bowl 32 of lower face is provided with several vertical straight slot 32a on the installation bowl 32, in the lower end spiral shell of the installation bowl 32
It is connected to a clamp nut 33.
The width of the pointer 9 is connected to one end of the shaft 7 from it to be had gradually to one end far from the shaft 7
The trend of reduction.
Using above-mentioned technical proposal, the laser ranging system C of the utility model, when use, rotates second laser rangefinder,
Make the first rangefinder and the second rangefinder to distinguish the distance of measurement distance two objects under test A, B be respectively b and a, measurement finishes
The rotation angle of record pointer is α afterwards, so as to which the distance between two objects under test c can be calculated according to the cosine law,
I.e.：c2=a2+b2-2abcosα。
The laser ranging system of the utility model, compared with the prior art in laser range finder, have measure two treat
The distance between object is surveyed, facility is provided to construction or detection.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not intended to limit the embodiments.For
For those of ordinary skill in the art, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments.And the obvious variation or change thus extended out
Among the dynamic protection domain created still in the utility model.
