Specific embodiment
Wind-driven generator tower verticality measurement device described in the utility model is carried out with reference to the accompanying drawings and embodiments
It is described in detail.
Wind-driven generator tower verticality measurement device described in the utility model includes disk 2, laser as shown in Figure 1
Emitter 5 receives target 8, electronic compass 7 and circular bubble 6；The laser beam emitting device 5 is arranged at by mounting seat 4
On disk 2, positioned at the center of disk 2, laser focusing knob 3 is provided on laser beam emitting device 5；The lower end of the disk 2 is set
It is equipped with support column 1；There are three 1 spaced sets of support column；The support column 1 is sequentially connected by several telescopic supporting rods of section
Composition；A centrally disposed through hole for the disk 2；As shown in Figure 5, Figure 6, the reception target 8 is set by connecting bearing 10
In the center of electronic compass 7.Azimuth scale is provided on electronic compass 7, LED illuminator 9 is embedded at azimuth scale.Receive mark
Target 8 is easily adsorbed in tower barrel platform bottom by magnetic bases.Lasing light emitter is provided on laser beam emitting device 5.Such as Fig. 4 institutes
Show, circular bubble 6 is nested on disk 2；Electronic compass 7 is integral with receiving target 8, and there is a circle azimuth scale mark in periphery
Know, may indicate that current N-S positions, and receive 8 body of target to be mutually rotatable with electronic compass 7；Centrally disposed the one of disk 2 is logical
Hole can make laser pass downwardly through the hole and be overlapped with center point alignment.
Blower fan tower barrel by it is several section form, every layer has platform, in vertical plane be projected as it is trapezoidal.Different towers are measured respectively
Laser point deviates Target Center value at cylinder podium level, calculates each section tower verticality and dip azimuth angle.It is first when measuring
It first passes through high accuracy circular spirit level 6 and adjusts the height leveling support construction of support column 1, meet transmitting laser vertical in level
Face.
It is combined as shown in fig. 6, receiving target 8 with electronic compass 7 by connecting bearing 10, is mutually linked, connection can be passed through
Bearing 10 mutually rotates, and by rotation N-S positions can be made to be overlapped with receiving 8 cross axis of target, the orientation at 7 edge of electronic compass
Scale precision is 3 °, can read the absolute or relative bearing for receiving laser and central point, have LED illuminator 9 below scale, lead to
It crosses and lights scale easily to indicate current N-S directions, receive the distance scale on target 8 and manual or automatic can read and swash
Luminous point is to Target Center distance.
By adjusting supporting rod in blower fan tower barrel base plane, make 6 bubble of circular bubble placed in the middle, flatten instrument, meanwhile,
As shown in figure 3, make laser beam by 2 centre bore of disk downwards withIt overlaps.At the second elevation plane, i.e., second section of tower is put down
Platform bottomPoint places laser pick-off target 8 by magnetic bases, and rotation target makes cross axis show N-S directions weight with scale
It closes.
FromPoint emits laser beam upwards, adjusts laser facula size by focusing screw, laser beam is handed over receiving target 8
In, readWith receiving the distance between 8 central point of target, recordAzimuth on target 8 is received。
WithBetween distanceIt can be drawn by tower design drawing, it also can be by、It is calculated, inclination is calculated
Angle, upper and lower center of circle offset is, then the tower verticality, well azimuth can finally be calculated
Angle is 180-。
Required tower verticality and non-critical for whole tower verticality above, there are certain error, correspondingly, can foundation
The method will receive target 8 as tower top Flange Plane, and accurate tower entirety verticality can be calculated.Likewise,
Also it can divide to cut and acquire tower verticality at different height, the purpose of detection tower overall structure quality is can reach by comparison.
With reference to foregoing description
Step 1：Lasing light emitter, leveling are placed on the first layer platform of tower door side, it is ensured that laser beam vertical level, and
Lasing light emitter floor projection is overlapped with Platform center point；
Step 2：Placement receives target 8 at second section of tower planar base center, makes Target Center point and Platform center
Point overlaps, and rotation target is so that cross axis is overlapped with the N-S directions currently indicated；
Step 3：Measure laser point and the distance of Target Center pointWith distance of the lasing light emitter apart from target, read laser
Azimuth of the point on target 8 is received；
Step 4：Calculate tower inclination angle, lower planes center of circle offset
, tower verticality, tower dip azimuth angle；
Wind-driven generator tower verticality measurement device described in the utility model can be directed to blower fan tower barrel uniform pitch with
Uneven inclination measures, and particularly with uneven inclination, has merogenesis tower squareness measurement computing function, and device is put
In tower into people side platform, avoid to be positioned over narrow and small tower flange in the bottom side platform space, equipment placement and personnel and operate and be stranded
The shortcomings that difficult.
