Description

A kind of automatic compensated level
Technical field
The utility model relates to a kind of optical analysis surveying instrument, and especially a kind of automatic compensated level is applicable to the usefulness of the various construction engineerings that need carry out measurement of the level.
Background technology
Spirit-leveling instrument is by providing a horizontal line of sight to carry out the instrument of measurement of the level, and the line at instrument center of reticule and telescope center constitutes straight line and is referred to as collimation axis.Traditional DS3 fixes the high-precision level device of a cover in telescopical side, utilize the horizontal properties of liquid surface to set up level reference (spirit-level axis), and utilize physical construction that the two ends of bubble are projected in the plane, judge the horizontality of bubble according to the degree that conforms to of two end projections.Equally, also utilize physical construction to guarantee that collimation axis is parallel with this spirit-level axis.By little device that inclines of regulating spirit-leveling instrument level two end projections being echoed fully during use---spirit-level axis is in horizontality, thereby guarantees that the telescopical collimation axis of spirit-leveling instrument is in horizontality.The degree of echoing of this bubble device depends on human factor, so error is bigger, and this can directly have influence on the precision of measurement of the level.In addition, when each observed reading, must echo level again, this also greatly reduces the work efficiency that field operation is measured.
Have the manual operation error at traditional DSZ3 automatic compensated level, influence the problem of measuring accuracy, the inventor reequips the high precision level device of DSZ3 automatic compensated level, facts have proved, measuring accuracy and work efficiency all improve greatly.
The utility model content
The purpose of this utility model: aim to provide a kind of automatic compensated level, adopt cover Anping compensator device to replace traditional high precision level device, manual operation error when preventing to observe is strengthened the measurement of the level precision, and can be improved field process efficient.
This automatic compensated level, form by fuselage 14, telescope 1, governor motion 2 and tribrach 6, it is characterized in that: in the telescope light path, autocompensation installation has been installed, this autocompensation installation be located at the fixing compensator fixed support 7 of fuselage 14 in, by intersect metal hang spring 4, place optical prism 3 and air damper 5 on the metal hang spring to form; Described metal hang spring 8 be by four groups of screws 9 and four groups of metal platen securing members 10 be fixed tightly in respectively with the fixed metal frame 11 of compensator fixed support 7 on, the other end of described metal hang spring 8 then is outstanding optical prism 3 then, thereby forms a free pendulum mass; Simultaneously, also be provided with in addition on the metal frame 11 by a fixing erecting prism that is imaged as erect image 13 on the cross-graduation plate of screw.
According to this automatic compensated level that above technical scheme proposes, the degree of accuracy height, easy to operate, can check the compensator working condition.

Embodiment
This automatic compensated level, form by fuselage 14, telescope 1, governor motion 2 and tribrach 6, it is characterized in that: this automatic compensated level, form by fuselage 14, telescope 1, governor motion 2 and tribrach 6, it is characterized in that: in the telescope light path, autocompensation installation has been installed, this autocompensation installation be located at the fixing compensator fixed support 7 of fuselage 14 in, by intersect metal hang spring 4, place optical prism 3 and air damper 5 on the metal hang spring to form; Described metal hang spring 8 be by four groups of screws 9 and four groups of metal platen securing members 10 be fixed tightly in respectively with the fixed metal frame 11 of compensator fixed support 7 on, the other end of described metal hang spring 8 then is the optical prism 13 that is suspending, thereby forms a free pendulum mass; Simultaneously, also be provided with in addition on the metal frame 11 by a fixing erecting prism that is imaged as erect image 13 on the cross-graduation plate of screw.
Autocompensation installation is installed between focusing lens and the cross-graduation plate, and the swing by prism itself changes collimation axis, thereby makes spirit-leveling instrument get final product operate as normal under the state of rough leveling.The round bubble of rough leveling is housed on the automatic compensated level, as long as in the working range of circle bubble, be about the scope of spirit-leveling instrument inclination ± 14 ' (standard of dispatching from the factory), the lateral error of the horizontal collimation line of instrument also very little (≤0.5 "/1 '); so human factor is less, thus improve the precision of measurement of the level greatly.In addition, when each observation,, work efficiency is improved greatly as long as guarantee that the circle bubble in working range, just need not to flatten again.
Described metal hang spring 8 is to be fixed tightly in respectively on the metal frame 13 by four groups of screws and metal platen securing member 9, and every hang spring strict guarantee length unanimity also imposes identical pulling force.The other end of hang spring then is to hang optical prism, thereby forms a free pendulum mass.On metal frame 11, also there are several screws to fix an erecting prism 13 in addition, make telescope on the cross-graduation plate, be imaged as erect image.Pendulum mass is installed on the telescopical collimation axis, and under spirit-leveling instrument was in heeling condition, pendulum mass can correct by optical principle produces collimation axis because of inclination error and come.
For preventing fortuitous event damage hang spring, a protective device is respectively arranged in the both sides of pendulum mass.The guard bar of automatic compensator both sides is placed in the circular hole of protective device; both gaps are very little; the free pendulum mass that can limit the hang spring formation of compensator when instrument is subjected to sharp pounding connects; when swinging, free pendulum mass drives piston; and the motion of damper piston in the damping box can recover stationary state soon because of being subjected to air resistance; so just can guarantee each Anping spirit-leveling instrument, pendulum mass can both settle out in several seconds.
Measuring all is operation in the open air basically, and temperature variation is very big throughout the year, considers the influence of temperature to instrument, and a temperature compensation sheet is arranged in the front of compensator, can guarantee that instrument can both operate as normal in-20 ℃ of-45 ℃ of scopes.
Anping spirit-leveling instrument is provided with review button, can check the compensator working condition.Instrument adopts friction catch, and unlimited micromotion mechanism is adopted in horizontal fine motion, for ease of the both sides that operate in instrument the fine motion handwheel has been installed all.
