Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
A kind of structural schematic diagram of sub-wire tube type rope saddle back court assembled positioning device shown in Figure of description it is found that
The utility model includes the stiff skeleton for installing sub-wire tube type rope saddle 4, is provided on stiff skeleton for positioning sub-wire pipe
Formula cable saddle 4 goes out the positioning bracket 2 of the spatial positions Ta Kou, is additionally provided on stiff skeleton for positioning 4 center of sub-wire tube type rope saddle
The bottom elevation limit for height steel plate 6 of line and elevation location and limit corner block 5, limit corner block 5 are fixed in bottom elevation limit for height steel plate 6
Upper surface, positioning bracket 2, bottom elevation limit for height steel plate 6 with limit the center axis of symmetry of 5 three of corner block it is conllinear.Stiffness bone
Frame includes that the going out tower mouth elevation being vertically installed on concrete platform 1 fixes channel steel 3 and center fixation channel steel 7, goes out tower mouth elevation
One rectangular-shape in the fixed besieged city of channel steel 3, center fix channel steel 7 and are set to out centre and the two that tower mouth elevation fixes channel steel 3
Center axis of symmetry is collinearly arranged, it is total to go out the central axis that tower mouth elevation fixes the central axis of channel steel 3 and channel steel 7 is fixed at center
Line.It is adjacent go out tower mouth elevation fix channel steel 3 between be connected with positioning bracket 2.Adjacent center is connected with bottom height between fixing channel steel 7
The high steel plate of degree 6.The central axis for limiting corner block 5 is conllinear with the central axis of stiff skeleton.Between adjacent fixed channel steel 3 and
Adjacent center is both provided with stull and scissors fork 8 between fixing channel steel 7.Bracket 2 is positioned to be one block of steel plate rather than use angle
Iron, it is ensured that the utility model sub-wire pipe in transportational process will not deform deviation, since fiber tube center is on circular curve, if
The method positioning sub-wire Guan Zetai that elevation is controlled with steel plate in the prior art is complicated, and uses limit corner block 5 (angle bar),
Dot center is marked on angle bar, is more advantageous on circular arc and is withstood center of arc.
When using the utility model (back court positioning),
By high-accuracy total powerstation, setting-out goes out stiff skeleton outer edge and drop point on concrete platform 1 first, is sprayed
Paint label.Stiff skeleton dropping place is rectified a deviation after erectting by levelling tube, and welding is fixed in time；
Then elevation location is carried out to center fixing groove steel 7 by high-accuracy total powerstation, is then fixed on channel steel 7 at center
Bottom elevation limit for height steel plate 6 carries out accurate measurement welded limiting corner block 5 on bottom elevation limit for height steel plate 6, by limit corner block 5,
Bottom elevation limit for height steel plate 6, center fix the whole central space position for controlling sub-wire pipe cable saddle 4 of channel steel 7, this is also phase of the present invention
For the key point of the prior art, the installation and debugging of sub-wire pipe cable saddle 4 are greatly facilitated by increasing a reference point；
Then tower mouth elevation is gone out to sub-wire pipe cable saddle and fixes the progress elevation location of channel steel 3, welding is fixed on going out tower mouth elevation fixation channel steel 3
Position bracket 2, by high-accuracy total powerstation to orienting out tower mouth anchor plate plan-position and elevation on positioning bracket 2.(back court is hung
Dress and positioning flow：Sub-wire tube type rope saddle 4 carried out label when dispatching from the factory to sub-wire pipe center of arc and anchor plate center,
By (channel steel 3 is with lateral extent inside and outside channel steel 7 between 7 center of the lifting of sub-wire tube type rope saddle 4 to fixed channel steel 3 and fixed channel steel
52cm, 4 anchor plate of sub-wire tube type rope saddle are 50cm, wherein reserved 2cm distances prevent channel steel welding error from causing sub-wire pipe cannot
Be properly placed cause torsion, deformation), by the center of arc of sub-wire tube type rope saddle 4 and anchor plate center alignment limit corner block 5 and
It positions on bracket 2 on measurement markers point, limit corner block 5 and positioning bracket 2 can be checked mutually, determine whether sub-wire pipe 4 becomes
Shape.Then it checks, record 4 data of sub-wire pipe, whether meet code requirement after welding, into next sub-wire tube type rope saddle 4
It measures.) complete at once to reinforce it using stull and scissors fork 8 after first segment sub-wire tube type rope saddle positions.Then again into
The next section sub-wire tube type rope saddle positioning of row.The present utility model positions for a component threaded pipe type cable saddle, and one group is 2 section sub-wires
Pipe, 1 section are 2 sub-wire pipes.
By this utility model and the method for invention, the positioning accuracy of sub-wire tube type rope saddle is not only made to meet requirement,
And position fixing process is flexibly, rapidly, has won the time for low-pylon cable-stayed bridge king-tower rapid construction, ensure that site operation progress
It is required that while improve measurement efficiency, also save a large amount of man power and material, have it is prodigious society and economic benefit.
It should be understood that these are only the specific implementation mode of the present invention, but protection scope of the present invention is not limited to
In this, any technical person familiar with the field within the technical scope disclosed by the invention, the variation that can readily occur in or is replaced
It changes, should be covered by the protection scope of the present invention.
Front court positions the comparison with back court positioning：
Wherein fundamental measurement flow welding L positioning angle steel control elevation, lift sub-wire tube type rope saddle anchor plate to L position
It on angle steel, is then fixed by the relative position of measurement and positioning anchor plate, then audited scores fiber tube arc section center elevation again.
And back court positioning is to complete stiff skeleton by first setting-out outer edge intersection point.Every sub-wire pipe is by two locating slots
Steel 3 (effect in terms of forming track of channel steel 7 is identical) and positioning bracket 2, limit corner block 5 are fixed, and 2 channel steel purposes (make
Sub-wire pipe forms track in hoisting process, prevents sub-wire pipe from leading to sub-wire pipe 4 under high wind conditions or under impact events certainly
The distortion and deformation of body.) and then by limiting corner block 5 fix sub-wire pipe center of arc, pass through and positions bracket 2 and fix sub-wire
Tube type rope saddle anchor plate.After the completion of lifting, practical upper limit corner block 5 and positioning bracket 2 can be checked mutually, determine sub-wire pipe
Whether deform.By whether meeting code requirement after finally measuring review and record sub-wire pipe welding.
Back court localization characteristics：1, wind-force is small, influences to reduce on measuring speed and precision；2, we increase sub-wire pipe into
Enter the track of skeleton, the probability of sub-wire tube type rope saddle 4 itself torsion or collision deformation can be reduced；3, it positions, install, before welding
Must having determined that sub-wire pipe, whether there is or not deformations, and front court positioning anchor plate completes 4 center of arc's elevation of audited scores fiber tube after welding
It can lead to the presence of duplicate measurements；4, the speed of surveying and locating can be undoubtedly improved in measuring with reference to the installation positioning of object, relatively
Short time measures the precision that can also improve achievement.
