Description
Technical field
The present invention relates to a kind of surveying instrument, especially relate to a kind of wirerope center and measure special wirerope center mensuration target framework.
Background technology
On great rivers, build suspension bridge at present get more and more, its feature is that span is large, handsome in appearance.In bridging process, the center of suspension cable wirerope measures, and be a difficult problem for building and designing unit, traditional way uses sexangle shelf, above being placed on by measuring instrument, calculates the error of measurement point, carry out repeated measurement, calculate reference point always.The shortcoming of this measuring method is: (1) is time-consuming.Repeated measurement, needs a large amount of survey crews, repeatedly carries out from each position.(2) there is error in measurement.Because measured point is in rocking in measuring process, so calculate bench mark data also there will be error in repeated measurement.
Summary of the invention
The object of the invention is to the difficult problem measured in erection process for above-mentioned suspension bridge wirerope, provide a kind of reasonable in design, measure accurate wirerope center and measure target framework.
In order to achieve the above object, the present invention has mainly come by the following technical solutions.The present invention is made up of universal connection side's framework of target framework and the vertical rod be located at below universal connection side's framework, universal connection side's framework forms square bearer by universal connection upper frame and with its supporting universal underframe that is connected, reflecting prism frame is provided with at the top of universal connection side's framework, reflecting prism frame is provided with reflecting prism, universal connection side's framework following on be provided with and allocate round bubble, universal the following of connection side's framework connects vertical rod by universal joint, sexangle heart steering column jacket is provided with at the center of universal connection side's framework, the center of sexangle heart steering column jacket is provided with sexangle wirerope hole, wirerope is placed in the center of sexangle heart steering column jacket, outer shaft is provided with outside sexangle heart steering column jacket, sexangle heart steering column jacket can rotate in outer shaft, sexangle heart steering column jacket is made up of upper and lower two semiaxis, semiaxis under semiaxis and sexangle heart steering column jacket can be divided on sexangle heart steering column jacket, on sexangle heart steering column jacket, under semiaxis and sexangle heart steering column jacket, semiaxis is fixed by some fixed screws, described outer shaft is also made up of semiaxis under semiaxis on outer shaft and outer shaft, fixed by some outer shaft fixed screws, be connected with left socle transverse axis and right support transverse axis between outer shaft with universal connection side's framework, left socle transverse axis is provided with left hold-doun nut, left-handed screw nut push rod is provided with in left hold-doun nut, outer shaft fixed by left-handed screw nut push rod, right support transverse axis is provided with right hold-doun nut, right nut push rod is provided with in right hold-doun nut, right nut push rod secures hexagonal heart steering column jacket.In order to prevent sexangle heart steering column jacket from skidding off outer shaft, be provided with baffle plate at the both ends of sexangle heart steering column jacket.
The present invention is a kind of instrument of measurement, so in use there is the operating procedure of its uniqueness.
1, install: the present invention is made up of two large divisions, and one is wirerope centering machine, i.e. sexangle heart steering column jacket and the outer shaft be located on its periphery.Two are provided at the universal connection side's framework on outer shaft.
2, sexangle heart steering column jacket is installed.Sexangle heart steering column jacket and the outer shaft be located on its periphery are all formed with two semicircles, during installation, first open sexangle heart steering column jacket and outer shaft respectively, the measurement point of selected wirerope, the sexangle heart steering column jacket of two semicircles being enclosed within wirerope, for ensureing the consistent of wirerope center and sexangle heart steering column jacket center, first having padded four limits of heart, pad double sticky tape again, prevent heart from sliding on wirerope.Heart otch seam when closing up up and down is very correct, tight, joint close, can not have some dislocation, fix with screw-driving.
3, outer shaft is installed.Will note consistent with sexangle heart steering column jacket when outer shaft is installed, two semiaxis close up to be wanted steadily easily, and joint close must align, and is screwed.Sexangle heart steering column jacket and outer shaft will keep rotating easily.
4, universal connection side's framework is installed.Universal connection side's framework is exactly universal gravitational orientation frame, first install the Lower Half of square bearer, check the length of vertical rod and hold-down nut is locked, whether universal joint puts in place, after the first half of square frame is installed, is checking and measuring the three-dimensional coordinate of the prism on square bearer.
The present invention compared with prior art, has following obvious advantage and innovation.(1) design science is reasonable, easy to operate.The present invention adopts and is located in universal connection side's framework, no matter wirerope tilts or rotates, it can keep eccentric vertical rod to be on the center line of wirerope, measures the three-dimensional coordinate of prism, just equals to have measured the three-dimensional coordinate that the length at wirerope center is exactly special target framework wirerope center.(2) easy for installation.The present invention adopts sexangle heart steering column jacket and the design of outer shaft semiaxis, when mounted, as long as be combined in outside wirerope by two-semiaxle, then connects just by square bearer, because wirerope is not only high but also long, only has and adopts this design just easily to measure.(3) save labor, alleviate the labour intensity of survey crew.Use of the present invention can change the phenomenon that tens traditional people turn round wirerope measuring point.As long as install target framework on the measurement point needed, the survey crew on ground just can measure required three-dimensional coordinate like a cork.(4) quality assurance, cost alleviates.
The present invention is applicable to the mensuration of the three-dimensional coordinate of suspension cable wirerope, is specially adapted to the mensuration of the wirerope of outstanding cable-stayed bridge.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
