Description
Technical field
The utility model relates to transit tripod annex, specifically is a kind of transit tripod centering leveling reference unit of realizing the leveling of transit tripod centering.
Background technology
The arrangement of transit mainly comprises neutralization leveling two parts, is the accurately important and primary link of observation of transit, and the precision of its arrangement and efficient will directly influence the precision of observation.In the transit observation of topographic condition more complicated such as soft or mountain region, the position of three foot rests need set up and fix to the arrangement of transit earlier, accomplishes the preliminary centering leveling, accomplishes the accurate centering leveling through moving with the foot bolt leveling of transit again.Concrete operation steps is: the leveling of (one) preliminary centering.Fixed tripod, range estimation judge that basic and corresponding point position, ground, the center of tripod cradle remains on the same perpendicular line, and make bearing end face maintenance level basically.(2) accurate centering leveling.Transit is installed, again through centralizer observation, is moved transit and tripod and reach centering, the foot bolt of adjustment transit makes circular bubble and pipe bubble reach leveling between two parties.The accurate leveling of transit and accurate centering need be carried out repeatedly, till the neutralization leveling is all arrived requirement.
The step phase one is because traditional tripod is just as support of transit observation and bearing, when the operator utilizes the naked eyes range estimation to judge the preliminary centering leveling of tripod; Normal inaccurate owing to what estimate; Make the preliminary centering of tripod bigger with preliminary leveling error, cause the accurate centering leveling of step 2 to need repeatedly adjustment repeatedly, What is more; When the moving range of transit in tripod cradle end face connecting hole satisfied not requiring of accurate centering; Need settle tripod again, promptly repeat the preliminary centering screed step of tripod, this just causes the arrangement of transit to carry out repeatedly; Not only wasted time and energy but also inefficiency, directly influenced the observed efficiency and the precision of transit.The Surveying Engineering of, equipment placement condition difference with a varied topography for the field, and survey station point is many and in the transit observation situation that observed object is few, the arrangement quick and precisely of transit seems particularly important to mapping operations.
Summary of the invention
Have big, the loaded down with trivial details problem consuming time of centering flattening course of centering leveling error in order to solve existing mode with range estimation centering leveling transit tripod, the utility model provides the transit tripod centering leveling that a kind of centering flattening course is convenient and swift, centering adjustment precision is high reference unit.
The technical scheme of the utility model:
Transit tripod centering leveling reference unit; It is installed on the tripod; It is characterized in that: the shell that comprises staircase structure; The laser alignment device is installed in the lower end of said shell, and said laser alignment device comprises laser diode, and said laser diode is connected with supplying cell, the control knob of controlling its switch respectively; In the upper end of said shell circular bubble is installed, said circular bubble is connected with the laser alignment device.
Further, said circular bubble is connected with the laser alignment device through ring gear.
Further, said shell is provided with the connecting line that is connected with tripod.
Further, the upper end diameter of said shell is slightly larger than the diameter of tripod cradle end face circular hole, its lower end diameter be slightly less than tripod cradle end face circular hole diameter and with tripod on the circular hole internal diameter that connects on the spiral identical.
Further, said shell is a plastic shell.
The technical conceive of the utility model utilizes transit tripod centering leveling reference unit to replace range estimation to judge the preliminary centering leveling of completion tripod, makes when setting up tripod, just satisfies centering leveling requirement basically.Overcome the inaccurate of range estimation judgement, avoided the adjustment repeatedly of transit centering leveling, made tripod centering leveling fast.And flatten through the preliminary centering of laser alignment device and circular bubble reference, because its accuracy is higher, can realize once regulating the accurate centering leveling that can accomplish transit usually.
When not using, transit tripod centering leveling reference unit is installed on the connection spiral of tripod, and is connected with tripod through connecting line.During the transit mapping, after the gauger opens tripod, transit tripod centering leveling reference unit is taken off in tripod connection spiral; Open laser alignment device button; Be placed on the tripod cradle end face circular hole, adjust three foot rests then, the laser point of laser alignment device is overlapped with survey station point; Make the circular bubble bubble placed in the middle, accomplish the preliminary centering leveling of tripod.Take off transit tripod centering leveling reference unit immediately, hang on the tripod, transit is placed on the tripod, accomplish accurate centering leveling operation steps through connecting line.After mapping is accomplished, close laser alignment device button before the gathering foot rest, and this device is contained in the bottom circular aperture that connects spiral.Because accomplish preliminary centering leveling preferably through transit tripod centering leveling reference unit, the range estimation determining method precision in more original method is higher, the time more economizes, and the accurate centering leveling of transit is once realized.
The effect intentionally of the utility model:
(1) set laser centralizer and circular bubble are applied in the transit tripod in the device of one, make the centering flattening course of transit become convenient and swift, have improved the efficient of mapping.
(2) the utility model is enclosure material with the plastic cement, can shockproof, shatter-resistant.The device one-piece construction is simple, with low cost, easy to implement, is easy to carry.It both can improve the arrangement speed of transit, also can improve the arrangement precision of transit, had broad prospect for its application.
