Description
Technical field
This utility model relates to engineering measuring technology field, especially a kind of quick centering leveling foot rest.
Background technology
The online approved of existing engineering survey foot rest and Patent Office announces foot rest, all has following weak point:
1) common foot rest:
A. thick circle blister on instrument (note: now tripod platform and horizontal plane still have certain angle) placed in the middle is made by telescopic leg lower limb method at ordinary times, relatively time consuming and need certain proficiency level.
B. thick gentle essence flat rear (now thick centering is inclined), need to translate instrument, so that instrument centering laser or optical centering device center overlap with ground survey station point.Because not indicating on tripod platform, during translation, the minor rotation of instrument all can affect smart flat instrument level.The angle of tripod platform and horizontal plane is more big, rotates the instrument level deviation effects after translation centering more big, needs that smart flat amplitude is also more big again, thus causing the survey station point deviation of centering on surface more big, therefore needs centering repeatedly to flatten, relatively time consuming.
2) the embedded round blister of common tripod platform:
A. slightly can only put down for foot rest before instrument sets up.Generally it is capped after instrument erection, such as foot rest generation accidental movement, can only flatten with spirit level on instrument.
B. slightly at ordinary times, circle blister on foot rest (note: in like manner now tripod platform and horizontal plane still have certain angle) placed in the middle is directly made by telescopic leg lower limb method.Still relatively time consuming and need certain proficiency level.
C. thick gentle essence flat rear (now thick centering is inclined), need to translate instrument, so that instrument centering laser or optical centering device center overlap with ground survey station point.Because tripod platform does not indicate, centering repeatedly is in like manner needed to flatten, relatively time consuming equally.
Though d. structure is simple, but require circle blister placed side parallel with tripod platform face (otherwise embedding round blister loses meaning).Therefore processing request is higher, relative cost is slightly higher point also.
E. set round blister and to have additional space, it is possible to land thickness need to be strengthened, maybe need genus portion to change platform structure.
F. round blister is consumable accessory, foot rest reciprocal is damaged and blister day post-equalization etc..
3) by the accessory part being made up of laser and circle blister:
A. in thick square of face, laser centring device and circle blister that instrument carries are acted as, so assembly has unnecessary suspicion.Way makes the assembly circle blister on tripod platform placed in the middle again by telescopic leg lower limb, then remain a need for putting down by instrument essence, because instrument base foot screw is adjustable, therefore instrument base upper and lower surface is uneven, though bottom surface overlaps with tripod platform, after foot rest is slightly put down by this assembly, under pedestal, bottom surface is also slightly put down, but not representing pedestal upper surface (i.e. instrument) is also level, moreover the precision of circle blister is well below envelope.
B. in centering, because being embedded in the middle circular hole of tripod platform when assembly is zero, general first visual estimation foot rest interstitial hole and ground survey station centering, because (using this assembly first thick to put down after thick putting down, otherwise, the not level that tripod platform is small just makes laser spots produce huge deviation with ground survey station point easily), laser is not necessarily directed at survey station point, Mobile foot stool is needed to carry out centering (because being embedded in the middle circular hole of tripod platform when assembly is zero, it is impossible to mobile.Just cannot fix as assembly can move temporarily, can fall), so original thick flat destroyed, must thick gentle thick centering again, front and back need repeatedly several times, time-consuming.
C. after foot rest is slightly put down, it is still necessary to the laser centring device carried with spirit level on instrument (the pipe blister that mainly precision is high) and instrument carries out precise alignment leveling.In like manner, tripod platform is mark no, and (reason is ibid, slightly), time-consuming to still need to the leveling of centering repeatedly.
D. structure slightly complexity, the cost such as assembly material expense and processing is slightly higher.
E. the later stage needs maintaining.
4) common foot rest repeats add assembling platform and adjusting knob:
The innovation of this type of foot rest is installed on tripod platform after simply being replicated by the pedestal of instrument, and reality does not play any improvement effect, can only become the burden of foot rest.
