Description
Technical field
The utility model belongs to building construction measurement technical field, be related to a kind of towering structure laser target centralized positioning without
Line transmission of video measuring system.
Background technology
The cooling tower design height in thermal power plant is generally at more than 100 meters, and higher and higher.State's electricity Ningxia Fan family Zhuan Fa
The indirect cool tower of 2 × 1000MW of power plant unit engineerings is the current domestic built highest indirect cool tower of height, its barrel is highly
210 meters.The first in the world indirect cool tower in domestic currently construction is high 2 × 660MW of the river low calorific value coals hair of Shanxi the Lushui River peace eldest son
The indirect cool tower of electric project, its barrel are highly 220m, a diameter of 128.097m of top exit.Domestic large and medium-sized thermal power plant
Chimney wall design height is generally 210m~275m, and chimney wall top exit diameter is generally 9m~20m or so.Firepower is sent out
Cooling tower, the chimney of power plant are divided by height, belong to towering structure.Its barrel horizontal cross-section is generally large diameter thin wall annulus
Type, in the work progress of barrel, in order to control the horizontal cross-section radius size of cooling tower (or chimney) barrel and stack shell to erect
To verticality, it is necessary to be carried out accurately to the center position in the ring-like section of every section horizontal thin-wall circular of barrel top surface in the construction process
Measurement and positioning.
The measuring method that this work in early days uses is " ceiling hammer centering method ".This measuring method principle is：With four steel
Cord is by " " arrangement, pulls one center hanging scaffold of suspension in barrel top surface, one is vertically hung again in the central point of hanging scaffold cross
A big ceiling hammer, aerial center hanging scaffold is moved horizontally by steel wire rope, when this plumb bob vertex (vertices) hung under hanging scaffold align it is cold
But it is used to control half during the centre coordinate control point on tower (or chimney) ground, when the center of hanging scaffold is exactly the section Wall Construction
The center reference point position of footpath measurement.Since the height of cooling tower (or chimney) barrel is big, this measuring method in practical operation,
Because the cotton rope length for hanging ceiling hammer is too long, cause in the case of having small wind effect even in the external world, plumb bob can also not stop back and forth
Ground is swung, and swinging pair is spent greatly, and the central point of hanging scaffold and the position of ground central point occur several centimetres to tens centimetres
Deviation, thus there are the problem of time of measuring is long, and measurement result accuracy is low for such a measuring method.
With scientific and technological progress, it is improved for the shortcoming of early stage " ceiling hammer centering method " technical problem, after
The measurement and positioning method of " laser beam centering method " occur again, this measuring method principle is：On cooling tower (or chimney) ground
One laser plummet of centre coordinate control point position of sound production, in advance adjustment sit the center of laser beam and ground perpendicular to the ground
The centering of control point position is marked, launches laser beam with the laser target disc of laser plummet to the drawing suspension of structures barrel top surface, leads to
Cross the eyepiece on laser plummet and visually observe position of the laser beam on laser target disc whether in, by adjusting drawing laser
The cable wire of target disc adjusts the horizontal level of laser target disc, when laser beam is overlapped with the center position on laser target disc, swashs
The center reference point position of measurement radius when the center of light target disk is exactly structures (cooling tower or chimney) Wall Construction
Put.This measuring method improves much compared with " the ceiling hammer centering method " of early stage.
But in recent years, as domestic thermal power plant unit scale not only increases, the knot of matched cooling tower and chimney
Structure size also not only is increasing, and the barrel altitude record of cooling tower and chimney not only is being refreshed, existing " laser beam pair
Middle method " also cannot little by little meet construction requirement.The reason is that exceed the structures Wall Construction of 150m for barrel design height
During, using " laser beam centering " mensuration, aerial laser target disc image is observed from the eyepiece of ground laser plummet
When, because judge distance is too remote, image obscures, and has been difficult the laser spot position seen clearly on laser target disc；In dusk, rainy days or mist
When extraneous natural environment light is bad, by the eyepiece of laser plummet, even height is less than on the laser target disc of 100m in haze day
Laser spot position can not all be seen clearly；Night because of dark, can not even more measure centering operation.So existing " laser beam
Centering " although measurement and positioning method improves in measuring accuracy, to the dependences of natural environment weather conditions requirement compared with
Height, and cannot meet the Alignment measuring work of cylinder of the Present Attitude more than 150m.
