Description
Technical field
It is particularly a kind of for the linear measurement for carrying out of main rope of suspension bridge the present invention relates to a kind of suspension bridge measuring instrument
Instrument.
Background technology
After the completion of the tight cable of main rope of suspension bridge, the linear of main push-towing rope need to be measured, master is calculated by surveying linear data
The installation site of cable folder and the length of main push-towing rope hoist cable.In order to reduce influence of the temperature to main push-towing rope absolute altitude, measurement is typically chosen in
12 points to 6 points of the late into the night is carried out, and measuring method is measured for Trigonometric Leveling by Total Station.Needed during gathered data survey crew main push-towing rope each
Prism is set up in characteristic point, there is the distance of 1.5m~1.7m away from Mao Dao due to main push-towing rope, need people to stand on ladder when setting up prism
Make prism bar hold mode by the way of hand steered vertically, and continue at least 2~3min, operating personnel measure by total powerstation
And gathered data；Subsequent point is transferred to after the completion of one characteristic point data collection to measure.So it is accomplished by expending a large amount of
Time and artificial, the cooperation between survey crew is also very tacit, not so will substantially reduce certainty of measurement.
The content of the invention
It is an object of the invention to provide a kind of measuring instrument for being exclusively used in main rope of suspension bridge linear measurement, in main rope of suspension bridge
During linear measurement, manpower is saved, and improve operating efficiency.
Technical scheme is as follows：
A kind of main rope of suspension bridge linear measurement instrument, it is characterised in that：It is vertical with the horizon rule including a horizon rule and one
Perpendicular chi, one end of the horizon rule is fixedly connected with the upper end of the perpendicular chi, the other end of horizon rule and a flexible steel band
One end is welded, and the other end of the steel band welds a screw rod, and a screw is provided with lower end on the perpendicular chi, and the screw rod is worn
The screw crossed on perpendicular chi is simultaneously fixed by nut；The fixed connecting rod vertical with horizon rule in two ends of the perpendicular chi, it is described
The end of connecting rod is connected with prism.
Simple structure of the present invention, it is easy to use, during for main rope of suspension bridge linear measurement, can be fixed on by self structure
On main push-towing rope and keep prism vertical, can greatly save artificial, and certainty of measurement is high, speed is fast, improves operating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is use state figure of the invention.
Specific embodiment
As shown in figure 1, the present invention includes a horizon rule 1 and a perpendicular chi 2 vertical with the horizon rule, the horizon rule 1
One end be fixedly connected with the upper end of the perpendicular chi 2, the welding of one end of the other end of horizon rule 1 and a flexible steel band 3, the steel
A screw rod 4 is welded with 3 other end, a screw is provided with the perpendicular chi 2 at lower end, the screw rod 4 is passed through on perpendicular chi
Screw is simultaneously fixed by nut 5；The connecting rod 6 vertical with horizon rule of two ends fixed of the perpendicular chi 2, the connecting rod 6
End be connected with prism 7.Connecting rod 6 is rotated by pivot structure with prism 7 and is connected.
During present invention specific implementation, level(l)ing bubble 8 can be also set on horizon rule 1, be easy to quickly adjust the perpendicularity of prism.
During present invention specific implementation, also scale can be set on perpendicular chi, scale is accurate to millimeter, is easy to carry out main push-towing rope diameter
Measurement.
The steel band can be easy to be wound during measurement using thick 2 millimeters, 3 centimetres wide of galvanized steel plain sheet, with enough flexibilities
On main push-towing rope.
As shown in Fig. 2 when carrying out main cable alignment measurement using the present invention, being temporarily fixed in the characteristic point for needing measurement.
Fixed form is：The screw rod that steel band is connected is removed from perpendicular chi first, horizon rule 1 leans against the top of main push-towing rope 9, perpendicular chi 2 leans against master
The side of cable 9, adjustment horizon rule 1 is in horizontality, and horizontality can quickly be adjusted by level(l)ing bubble 8；Steel band 3 is bypassed again
Main push-towing rope 9, and be connected with perpendicular chi by screw rod 4, nut 5 is tightened, measuring instrument is fixed on above main push-towing rope 9.Due to erecting chi upper and lower two
Prism 7 is installed in the end of individual connecting rod 6, so erects the prism bar that chi 2 is equivalent to common survey mode, and manually not hand steered
Vertical state can be kept.Rotating prism 7 makes its alignment total powerstation just can carry out trigonometric levelling.
After the completion of trigonometric levelling, main push-towing rope lower section can be leaned against with common horizon rule, one end is read on perpendicular chi near perpendicular chi
The scale in face is the diameter for obtaining main push-towing rope, by the relation of central point mark line above main push-towing rope diameter and perpendicular chi, you can obtain master
The absolute elevation at cable center.
