Abstract
The utility model discloses a fixing device of a steel cable centering mechanism of a suspension steel cable measuring beacon frame. The fixing device comprises a centering mechanism arranged on a U-shaped surveying and mapping frame, wherein the centering mechanism comprises an inner core and an outer rotating shaft arranged outside the inner core; the inner core is divided into upper and lower semi-circles and is fixed by a plurality of screw spikes; the outer rotating shaft is also divided into upper and lower semi-circles and is fixed by a plurality of screw spikes; the outer rotating shaft is sleeved on the inner core and can rotate on the inner core; antislip blocks are arranged at the two ends of the inner core respectively to prevent the inner core from slipping off; the outer rotating shaft is installed on the U-shaped surveying and mapping frame; a left support horizontal shaft and a right support horizontal shaft are arranged on the two sides of the outer rotating shaft respectively; a right support nut is arranged on the right support horizontal shaft and is used for fixing the outer rotating shaft; a left support nut is arranged on the left support horizontal shaft; and a lengthened fixed combination horizontal shaft is also arranged on the left support nut and passes through the outer rotating shaft to fix the inner core. The fixing device is suitable for measuring suspension steel cables.
Description
Technical field
The utility model relates to a kind of measurement target framework, and the suspension cable wirerope of especially measuring the suspension cable wirerope is measured the stationary installation of the wirerope centering machine of target framework.
Background technology
Build suspension bridge at great rivers at present more and more, its feature is that span is large, and is handsome in appearance.In the bridging process, the center of suspension cable wirerope is measured, and is the difficult problem of building and designing unit always, and traditional way is to use the sexangle shelf, above measuring instrument is placed on, calculates the error of measurement point, carries out repeated measurement, calculates reference point.The shortcoming of this measuring method is: (1) is time-consuming.Repeated measurement needs a large amount of survey crews.(2) there is error in measurement.Because the measured point is in rocking in measuring process.Also there is at present the wirerope of employing centering machine to measure, owing to be to endeavor to gain the upper hand axle sleeve on interior axle, so the shortcoming that axle moves in also existing.
Summary of the invention
The purpose of this utility model is the difficult problem measured for above-mentioned suspension bridge wirerope in erection process, provide a kind of reasonable in design, structure is ingenious, measure the wirerope centering machine stationary installation that the accurate suspension cable wirerope of measuring the suspension cable wirerope is measured target framework.
In order to achieve the above object, the utility model is mainly finished by the following technical solutions.The utility model is comprised of the centering machine of being located on the U-shaped mapping frame, centering machine comprises inner core and is located at the outer outer shaft of inner core, inner core is divided into up and down two semicircles, fix with some screws, outer shaft also is divided into up and down two semicircles, fixes with some screws, outer shaft is enclosed within on the inner core, can rotate at inner core, skid off in order to prevent inner core, be respectively equipped with anti-drop block at the two ends of inner core.Outer shaft is contained on the U-shaped mapping frame, both sides are respectively equipped with left socle transverse axis and right support transverse axis, the right support transverse axis is provided with support nut, be used for fixing outer shaft, the left socle transverse axis is provided with the left socle nut, also be provided with the fixed combination transverse axis of lengthening on the left socle nut, the fixed combination transverse axis passes outer shaft, is used for fixing inner core.
The utility model compared with prior art has following obvious advantage.(1) rational in infrastructure, easy to operate.The utility model adopts inner core and outer shaft all is divided into two semicircles, in use, can on the suspension wirerope that need are measured is taken up an official post measurement point two semicircles be put just, needn't overlap into from the end of wirerope.(2) measure conveniently.When measuring, be located at the outer outer shaft of inner core as long as rotate, the measurement point of just can having harmonized, very convenient, also guaranteed measurement efficient, alleviated labour intensity.(3) design of fixed combination transverse axis is ingenious.Outer shaft is contained on the U-shaped mapping frame, both sides are respectively equipped with left socle transverse axis and right support transverse axis, the right support transverse axis is provided with support nut, be used for fixing outer shaft, the left socle transverse axis is provided with the left socle nut, also be provided with the fixed combination transverse axis of lengthening on the left socle nut, the fixed combination transverse axis passes outer shaft, is used for fixing inner core.
The utility model is applicable to measure the suspension cable wirerope.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
