Description
Technical field
The present invention relates to a kind of suspension bridge survey tool, and in particular to a kind of prism measured for suspension bridge Datum Strand
Bar.
Background technology
Before the general Strand Erection of main rope of suspension bridge, benchmark rope need to be measured, by measured data to benchmark rope
Sag, which is adjusted, reaches design attitude.In order to reduce influence of the temperature to main push-towing rope absolute altitude, measurement is typically chosen at dead of night
12 points to 6 points progress, measuring method measures for Trigonometric Leveling by Total Station.Need survey crew each in Datum Strand during gathered data
Prism is set up in characteristic point, because main push-towing rope has 1.5m~1.7m distance away from cat road, people station is needed when setting up prism on ladder
Make prism bar vertical by the way of hand steered, and in total powerstation gathered data, at least 2 are continued by the hand-held prism bar of survey crew
~3min is in vertical state, waits transferring to subsequent point after the completion of data acquisition and measure.So it is accomplished by expending a large amount of
It is artificial, it is less efficient, and keep vertical using artificial hand steered prism bar, can occur error because of human factor unavoidably, influence is surveyed
Accuracy of measurement.
The content of the invention
It is an object of the present invention to provide a kind of prism bar for being exclusively used in the measurement of suspension bridge Datum Strand, it is to avoid benchmark rope
Substantial amounts of artificial consuming during stock measurement, saves labour turnover, and improves measurement accuracy and operating efficiency.
Technical scheme is as follows：
A kind of prism bar measured for suspension bridge Datum Strand, it is characterised in that：Including a hexagonal clamp, described six
Side clamp is bolted by two symmetrical fasteners and formed, and each fastener includes 3 sides, one of horizontal edge,
The two ends of the horizontal edge connect one and hypotenuse of the horizontal edge in 120 ° of angles respectively, the lower end of each hypotenuse provided with stretch out and with
The parallel otic placode of horizontal edge, the otic placode is provided with screw, and two fasteners are relative to be fastened, and passes through the screw bolt on otic placode
Connection；The middle part of each horizontal edge connects a prism bar vertical with horizontal edge, and the end of the prism bar is provided with prism.
The present invention is simple in construction, easy to use, when being measured for suspension bridge Datum Strand, can be fixed on by self structure
On Datum Strand and keep prism vertical, it is manually hand steered without survey crew, human cost, and measurement accuracy can be greatlyd save
High, speed is fast, improves operating efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
As shown in figure 1, the present invention includes a hexagonal clamp 1, the hexagonal clamp 1 is led to by two symmetrical fasteners
Cross bolt connection to form, each fastener includes 3 sides, one of horizontal edge, the two ends of the horizontal edge connect one and horizontal stroke respectively
Side is in the hypotenuse of 120 ° of angles, and the lower end of each hypotenuse, which is provided with, to stretch out and the otic placode 2 parallel with horizontal edge, on the otic placode 2
Provided with screw, two fasteners are relative to be fastened, and is connected by the screw bolt 3 on otic placode；The middle part connection of each horizontal edge
One prism bar 4 vertical with horizontal edge, the end of the prism bar 4 is provided with prism 5.Prism is rotated with prism boom end and is connected.
The present invention is easy to quick and precisely adjust prism bar when it is implemented, level(l)ing bubble 6 can be set on the prism bar
Perpendicularity.
When the present invention makes, hexagonal clamp, as raw material, is manufactured using 5 millimeters of steel plate by lathe process.Six
Depending on diameter of the size of side clamp according to Datum Strand, it is advisable so that Datum Strand can be clamped.
The present invention is in use, can be temporarily fixed at Datum Strand each needs in the characteristic point of measurement.First hexagon is pressed from both sides
Two fasteners of tool are separated, and are fastened on one on the other on Datum Strand；By the level(l)ing bubble on prism bar, prism bar is adjusted
For plumbness；Then two fasteners are connected by bolt, it is so manually not hand steered to keep hanging down for prism bar
Straight state.Rotating prism makes its be directed at total powerstation direction, by total powerstation gather above and below prism data, two data are averaged
Value is the absolute coordinate at Datum Strand center, you can complete measurement.
Claims (2)
1. a kind of prism bar measured for suspension bridge Datum Strand, it is characterised in that：Including a hexagonal clamp, six side
Clamp is bolted by two symmetrical fasteners and formed, and each fastener includes 3 sides, one of horizontal edge, institute
The two ends for stating horizontal edge connect one and hypotenuse of the horizontal edge in 120 ° of angles respectively, the lower end of each hypotenuse provided with stretch out and with horizontal stroke
