Description
Technical field
The invention belongs to engineering measuring technology field, more particularly to a kind of forced centering observation stand elevation carrection adjutage
Device.
Background technology
At present, in engineering survey, forced centering observation stand is one of highly desirable important tool used of measurement, is forced
Centering observation is made up of the observation pier forced centering bar at observation pier pier body and its top, and observation pier forced centering bar has shoulder
Plane and being used in shoulder plane are spirally connected and set up the top bolt of pertinent instruments.But needing Precision Elevation data
Measurement operation in, it is necessary to the measurement of higher degree of observation pier ground bench mark is delivered into observation pier forced centering bar shoulder plane
The height at place gets on, so that just observation pier forced centering bar shoulder plane is to observe the phase center that pier top portion sets up instrument
Elevation plane is surveyed and sets high-precision altitude data, and the design feature yet with observation pier itself is determined, uses the measurement of the level
Be unable to direct measurement and reach observation pier forced centering bar shoulder plane, steel ruler and hand-held rangefinder can not vertical survey arrive, therefore
This is for some large-scale or critical facilitys, such as aerial key position of high building, Dun Ta, stadiums, it is impossible to which survey is set to than three
Angle measurement of higher degree method altitude data more accurately more than second grade leveling precision, then makes observation pier strong using extending arm assembly
Centering rod shoulder plane processed extends out and measures the selection that necessitates.
Chinese utility model patent CN201120196989.X discloses a kind of forced centering observation stand and is prolonged with elevation carrection
Semi-girder device, including rectangular shape principal arm crossbeam, be provided with center fixing threaded hole through upper underbeam face on the principal arm crossbeam, have
During body application, observation pier forced centering bar top bolt is vertically inserted in the center fixing threaded hole of principal arm crossbeam, make principal arm horizontal
The underbeam face stretcher of beam in the shoulder plane of observation pier forced centering bar, now the underbeam face of principal arm crossbeam and forced centering bar
Shoulder plane can be considered in the same plane；Because observation pier forced centering bar is a prefabricated component, typically in observation pier
Inlayed with cement during fabrication and installation, it is difficult to ensure that the shoulder plane of the prefabricated components is observation pier forced centering bar shoulder
The severity of facial planes, when actually used, often jack-up directly sets up thereon observation pier forced centering bar shoulder plane
Principal arm crossbeam underbeam face, error is produced when causing measurement, so by setting up groove, trammel, inner thread sleeve and regulation
Bolt, using observation pier forced centering bar as one end supporting fixing point during using, is propped up with two bolts as two other
Support point is supported on the upper pier face of observation pier pier body, regulating bolt is screwed under the control of pincers worker level meter and then controls trammel to exist
Tilted and pushed in observation pier forced centering bar shoulder plane, so as to realize finely tuning principal arm crossbeam horizontality, subtracted
Few certain error.
But observation pier forced centering bar is finely adjusted as supporting fixing point by acting on regulating bolt, control
When trammel is tilted and pushed in observation pier forced centering bar shoulder plane, to observation pier forced centering bar top bolt and
On the principal arm crossbeam of matching center fixing threaded hole position produce shear stress, force between bolt and screw occur relative motion or
The trend of relative motion, so that screw deforms, is unfavorable for the dismounting and reuse of whole device, reduces whole
The service life of device.Additionally, the device also needs to be further provided with pincers worker level meter in actual use to be controlled regulation,
Using also inconvenient.
