Description

A kind of total powerstation centering rod of automatic upright
Technical field
The utility model relates to a kind of centering rod, is specifically related to a kind of total powerstation centering rod of automatic upright.
Background technology
In engineering survey, total powerstation is a kind of instrument that frequency of utilization is the highest.Total powerstation collects the ray that prism apparatus reflects in use, to carry out surveying work.After measurement, utilize lens optical center concentric with prism bar, when prism bar is vertical, the consistent principle of sharp planimetric coordinates is bored in lens optical center and prism bar bottom, can survey and sets out correct coordinate and put position.But surveying in reality establishes in process, operating personnel are difficult to the centering rod absolute vertical controlling erection prism, cause measurement markers result inaccurate.
When carrying out telemeasurement, the process that total powerstation sights prism is more consuming time, and the operating personnel of centering rod need keep transfixion for a long time, very easily tired.Although have centering rod special stand at present, its principle is similar to tripod, and leveling process wastes time and energy.
Utility model content
In order to overcome the defect that above-mentioned prior art exists, the purpose of this utility model is the total powerstation centering rod providing a kind of automatic upright, the utility model ensure that the centering rod absolute vertical of erection prism, and measurement markers result is accurate, meanwhile, the labor intensity of operating staff of centering rod also reduces greatly.
For achieving the above object, the utility model adopts following technical scheme:
A kind of total powerstation centering rod of automatic upright, comprise the centering body of rod that can stretch and the prism being fixed on centering body of rod top by prism clamping device, the center of gravity of described prism is positioned on centering body of rod axial line, centering body of rod lower end is provided with leveling bubble device and calibrating installation, the lower end of the centering body of rod is also provided with balance device, balance device comprises the balanced ball connecting link of inverted U and is symmetricly set on two balanced balls of balanced ball connecting link end, described balanced ball connecting link is symmetrically fixed on the lower end of the centering body of rod, the tapered rod underfooting of the centering body of rod is also provided with lower cushion block, make the center of gravity of the centering body of rod lower than tapered rod pin.
Further, the described centering body of rod comprises pole body and lower pole body, and the diameter of upper pole body is less than the diameter of lower pole body, make pole body just can stretch into lower pole body inner, and the junction of the two is provided with locking device.
Further, described leveling bubble device comprises leveling bubble and base, and base is connected with the centering body of rod is vertical, and leveling bubble is located on base.
Further, described calibrating installation comprises the calibration screw arranged perpendicular to the centering body of rod and the calibration nut be connected with calibration screw.
Further, lower cushion block is truncated cone-shaped, and its end face center is provided with back taper groove, and the tip of tapered rod pin is placed in this back taper groove.
Further, when the centering body of rod is placed on lower cushion block, balanced ball is not in contact with the ground, and centering rod body can be that fulcrum freely rotates with lower cushion block.
Further, the cross bar of calibration screw and balanced ball connecting link is in the same plane, and this plane is vertical with the centering body of rod.
Further, the described centering body of rod is carbon fibre material.
Compared with prior art, the utility model has following useful technique effect:
The utility model is provided with balance device, and because the overall center of gravity of the centering body of rod is moved to below tapered rod pin by balance device, and balance device is a kind of fixing parts.The self-poise of the centering body of rod can be realized: when the centering body of rod falls down time according to principle " object that potential energy is low is more stable; object is bound to change towards the state that potential energy is low ", because the balance device concentrating most of center of gravity can be elevated, so just cause potential energy to increase, so after vertically placing the centering body of rod, the centering body of rod would not fall down (similar roly-poly principle).Can measure after regulating calibration nut that the leveling bubble of leveling bubble device is located at middle position again, the utility model improves the accuracy of total station survey data, alleviate the labour intensity of survey crew, and structure is simple, easy to operate.
