Description
Technical field
It the utility model is related to a kind of suspension bridge measuring instrument, particularly a kind of survey for progress linear to main rope of suspension bridge
Measure 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 progress of the late into the night, measuring method measure for Trigonometric Leveling by Total Station.Need survey crew each in main push-towing rope during gathered data
Prism is set up in characteristic point, because main push-towing rope has away from cat road 1.5m~1.7m distance, people station is needed when setting up prism on ladder
Make prism bar hold mode vertical by the way of hand steered, 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.Thus need to expend largely
Time and artificial, the cooperation between survey crew is also very tacit, not so will substantially reduce measurement accuracy.
The content of the invention
The purpose of this utility model is to provide a kind of measuring instrument for being exclusively used in main rope of suspension bridge linear measurement, in suspension bridge
In main cable alignment measurement process, manpower is saved, and improve operating efficiency.
The technical solution of the utility model 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, is provided with a screw at lower end on the perpendicular chi, the screw rod is worn
Cross the screw erected on chi and fixed by nut；The fixed connecting rod vertical with horizon rule in both ends of the perpendicular chi, it is described
The end of connecting rod is connected with prism.
The utility model is simple in construction, easy to use, during for main rope of suspension bridge linear measurement, can consolidate by self structure
It is scheduled on main push-towing rope and keeps prism vertical, it is manually not hand steered, it can greatly save manually, and measurement accuracy is high, speed is fast, improves
Operating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state figure of the present utility model.
Embodiment
As shown in figure 1, the utility model includes a horizon rule 1 and a perpendicular chi 2 vertical with the horizon rule, the level
One end of chi 1 is fixedly connected with the upper end of the perpendicular chi 2, one end welding of the other end of horizon rule 1 and a flexible steel band 3, institute
The other end for stating steel band 3 welds a screw rod 4, is provided with a screw on the perpendicular chi 2 at lower end, and the screw rod 4 passes through perpendicular chi
On screw and fixed by nut 5；Fixed one connecting rod 6 vertical with horizon rule of both ends of the perpendicular chi 2, the connection
The end of bar 6 is connected with prism 7.Connecting rod 6 is rotatablely connected with prism 7 by pivot structure.
The utility model is easy to hanging down for quick adjustment prism when it is implemented, can also set level(l)ing bubble 8 on horizon rule 1
Straight degree.
The utility model on perpendicular chi when it is implemented, can also set scale, scale is accurate to millimeter, is easy to main push-towing rope diameter
Measure.
The steel band can use thick 2 millimeters, wide 3 centimetres of galvanized steel plain sheet, have enough flexibilities, be easy to wind during measurement
On main push-towing rope.
As shown in Fig. 2 when carrying out main cable alignment measurement using the utility model, the characteristic point for needing to measure is temporarily fixed at
On.Fixed form is：The screw rod that steel band connects is removed from perpendicular chi first, horizon rule 1 leans against the top of main push-towing rope 9, and perpendicular chi 2 leans against
The side of main push-towing rope 9, adjustment horizon rule 1 are in horizontality, and horizontality can quickly be adjusted by level(l)ing bubble 8；Again steel band 3 around
Main push-towing rope 9 is crossed, and screw rod 4 is connected with perpendicular chi, nut 5 is tightened, measuring instrument is fixed on above main push-towing rope 9.Due to two above and below perpendicular chi
Prism 7 is installed in the individual end of connecting rod 6, and so perpendicular chi is equivalent to the prism bar of common survey mode, and manually not hand steered
Vertical state can be kept.Rotating prism makes its alignment total powerstation to carry out trigonometric levelling.
After the completion of trigonometric levelling, it can be leaned against with common horizon rule below main push-towing rope, one end is read on perpendicular chi close to perpendicular chi
The scale in face obtains the diameter of main push-towing rope, passes through 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.
