Description
Technical field
The invention belongs to engineering measuring technology field, particularly relate to a kind of forced centering observation stand elevation carrection adjutage device.
Background technology
At present, in engineering survey, forced centering observation stand is that measuring height needs one of important tool used, forced centering observation stand is formed by observing the observation pier forced centering bar at pier pier body and top thereof, and observation pier forced centering bar has shoulder plane and is positioned at the top bolt in order to the erection pertinent instruments that is spirally connected in shoulder plane.But in the measurement operation needing Precision Elevation data, the height measurement of higher degree of observation pier ground bench mark being delivered to observation pier forced centering bar shoulder plane place is needed to get on, thus high-precision altitude figures is established in the elevation plane survey namely observing the phase center of pier top erection instrument with regard to observing pier forced centering bar shoulder plane, but owing to observing the design feature of pier self determine, use measurement of the level directly not measure and take things philosophically survey pier forced centering bar shoulder plane, steel ruler and hand-held stadimeter can not arrive in vertical survey, so large-scale or critical facilitys for some, as high building, Dun Ta, the aerial key position of stadiums etc., the altitude figures be set to more than than Trigonometric Leveling more accurately second grade leveling precision cannot be surveyed, so use adjutage device to make observation pier forced centering bar shoulder plane extend out to carry out measurement to necessitate selection.
Chinese utility model patent CN201120196989.X discloses a kind of forced centering observation stand elevation carrection adjutage device, comprise the principal arm crossbeam of rectangular shape, this principal arm crossbeam runs through underbeam face and is provided with center fixing threaded hole, during embody rule, observation pier forced centering bar top bolt is vertically inserted in the center fixing threaded hole of principal arm crossbeam, make the underbeam face stretcher of principal arm crossbeam 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, normally inlay with cement in observation pier fabrication and installation process, be difficult to ensure that namely the shoulder plane of these prefabricated components observes the severity of pier forced centering bar shoulder plane, during actual use, observation pier forced centering bar shoulder plane often jack-up directly sets up the underbeam face of principal arm crossbeam thereon, cause during measurement and produce error, so by setting up groove, trammel, inner thread sleeve and adjusting bolt, to observe pier forced centering bar support point of fixity as one end in use procedure, be supported on the upper pier face of observation pier pier body with two bolts as two other strong point, under the control of pincers worker level meter, screw adjusting bolt and then control trammel and carry out tilting and pressing down in observation pier forced centering bar shoulder plane, thus realize finely tuning principal arm crossbeam horizontality, reduce certain error.
But observation pier forced centering bar is as support point of fixity, finely tune by acting on adjusting bolt, when control trammel carries out tilting and pressing down in observation pier forced centering bar shoulder plane, shear stress is produced to observing fixing threaded hole position, center on the principal arm crossbeam of pier forced centering bar top bolt and coupling, force the trend that relative motion or relative motion occur between bolt and screw, thus screw is deformed, be unfavorable for the dismounting of whole device and reuse, reducing the serviceable life of whole device.In addition, this device also needs to be equipped with pincers worker level meter in addition in actual use and carries out regulating and controlling, uses also inconvenient.
