Specific implementation mode
Embodiment:
The tool of a kind of concrete pylon cable guide pipe accurate-location device of the present invention and its localization method is shown in conjunction with attached drawing Body embodiment, the oral area periphery of 6 nozzle of the cable guide pipe have the anchor plate 7 being centrosymmetrically arranged about nozzle, the anchor The periphery of 7 cross section of backing plate is square, and therefore, the distance at each edge to the 6 nozzle center of cable guide pipe of anchor plate 7 is equal.
First, as shown in Figure 1, Figure 2, the positioning device includes positioning panel 1, the positioning panel 1 is T-shaped plate, The T-shaped plate includes the first plate body and vertically disposed second plate body of first plate body, and first plate body has along its length The first axle extended is spent, second plate body has the second axis extended along a length thereof, the first axle and the second axis The point of intersection of line is equipped with conical socket 2, and the cone tip part of the conical socket 2 is equipped with for positioning 6 nozzle center of the cable guide pipe Location hole.
As shown in Fig. 2, the positioning panel 1 be equipped with the first scale, first scale using the location hole as origin, Extending outwardly label along the length direction of first plate body and the second plate body, the least unit of first scale is 1mm, Per 10mm, work has length mark.
Be additionally provided in the positioning panel 1 for 7 mutually fixed fixing device of the anchor plate, the fixing device packet Include corresponding to each free end of first plate body and the second plate body be arranged can be along the length of the first plate body or the second plate body Three sliding clamps 3 that degree direction slidably reciprocates, the sliding clamp 3 have for the block inconsistent with 7 outer rim of anchor plate 31, as shown in Figure 1, being each equipped with limit knob 4 on sliding clamp 3 and being fixed on positioning panel 1 by the limit knob 4 On to realize being relatively fixed between positioning panel 1 and anchor plate 7.
The sliding clamp 3 is equipped with the second scale for sliding along bearing mark, and the overall length of second scale is 19mm, least unit 0.95mm, per 1.9mm, work has length mark.
In addition, being additionally provided with the levelling tube for adjusting the cable guide pipe 6 and 7 level angle of anchor plate on second plate body 5。
The sliding clamp 3 of the pointing device design can slidably reciprocate in positioning panel 1, by with the use of limit revolve Button 4 can be achieved at the same time opposite between fixation and positioning panel 1 and anchor plate 7 between sliding clamp 3 and positioning panel 1 It is fixed, it is easy to operate and convenient for disassembly and assembly, avoid resulting in waste of resources in work progress and environmental pollution, and can Reusability, It greatly reduces construction cost while improving speed of application.
In actual mechanical process, by taking the second plate body as an example, it was demonstrated that positioning panel 1 and the sliding clamp being matched therewith The size scale designed on 3, up to 0.05mm, proves that principle is as follows to the positioning accuracy at 6 nozzle center of cable guide pipe:
By positioning panel 1 with the design parameter for sliding clamp 3 it is found that the origin of the first scale is location hole, least unit For 1mm, per 10mm, work has length mark, and the overall length of the second scale is 19mm, least unit 0.95mm, per 1.9mm, work has length Scale designation.
Assuming that the distance at each edge of anchor plate 7 to 6 nozzle center of cable guide pipe is abc.de mm, and for convenience of proving, rule Determine the positive integer that a, b, c, d, e are 0~9, so:
Abc.de=100 × a+10 × b+c+0.1 × d+0.01 × e (1)
Note N is taken as the integer of 0.de/0.05=(2 × d+0.2 × e) to round up, then 0.05 × N of 0.de ≈, due to D, e is 0~9 positive integer, so N ∈ [0,20];
Remember error delta=0.de-0.05 × N, due to N be 0~20 integer, so δ is accurate to 2 significant digits, then 0.de=0.05 × N+ δ, and since N takes the mode to round up, the part cast out and supplied is respectively less than 0.025mm, because This, δ ∈ (- 0.025,0.025);
Coarse adjustment is slided position of the clamp 3 on the second plate body and is between ab.c and ab. (c+1) cm scales, then When fine tuning sliding clamp 3 makes it slowly close to from the location of outside 0.demm distances of ab.c cm scales, slide on clamp 3 Nth bar scale to the second plate body on the distance between ab.c cm scales Dn should be 0.demm+0.95 × n mm, then:
Dn=0.de+0.95 × n
≈0.05×N+0.95×n
≈0.05×n+0.95×n+0.05×(N-n)
≈n+0.05×(N-n)
Wherein, [0,19/0.95] n ∈, i.e. n ∈ [0,20], therefore, when n, [0,20] N ∈, 0.05 × (N-n) ∈ [- 1,1], when N=n, Dn ≈ N, at this point, sliding ab.c cm scales on the nth bar scale to the second plate body on clamp 3 The distance between about N mm;
Since the first scale least unit on the second plate body is 1mm, on the second plate body, there are a certain scales and sliding to block Nth bar scale on son 3 overlaps, so, the mark that judgement sliding clamp 3 is adjusted in place is the nth bar above the sliding clamp 3 Scale is overlapped with a certain scale on the second plate body just.
First scale and the second scale are respectively used to the position of coarse adjustment and fine tuning sliding clamp 3 in positioning panel 1, sliding The mark that clamp 3 is adjusted in place is that the nth bar scale on the sliding clamp 3 is overlapped with a certain scale on the second plate body just, Location hole is that 6 nozzle center of cable guide pipe greatly improves construction quality to realize efficient precise positioning.
Secondly, in conjunction with shown in Fig. 3 to Fig. 5, the localization method includes the following steps:
Step 1):Positioning panel 1 is placed on anchor plate 7, has scale to place up;
Step 2):According to the design parameter of cable guide pipe 6 and anchor plate 7 it is found that each edge of anchor plate 7 to cable guide pipe 6 is managed The distance at mouth center is equal, chooses the sliding clamp 3 on opposite both sides respectively with the outer rim clamping of anchor plate 7, reads two respectively The reading for sliding clamp 3, is denoted as L1、L2
Step 3) corresponds to coarse adjustment and each sliding clamp 3 of fine tuning in positioning panel respectively using the first scale and the second scale Position on 1, the sliding fine tuning of clamp 3 mark in place be nth bar scale on the sliding clamp 3 just in positioning panel 1 A certain scale overlap so that the reading residing for three sliding clamps 3 isLocation hole position is cable guide pipe 6 nozzle centers;
Step 4):It tightens three limit knobs 4 successively three sliding clamps 3 are fixed in positioning panel 1, and then by Block 31 on sliding clamp 3 realizes being relatively fixed between positioning panel 1 and anchor plate 7;
Step 5):By the level angle of the adjustment cable guide pipe 6 of levelling tube 5 and anchor plate 7 to design angle, as shown in figure 5, The bubble in levelling tube 5 should be at centered horizontal state at this time;
Step 6):As shown in figure 3, the bar point of total station prism bar 8 to be vertically disposed in the position of location hole, pass through whole station Instrument surveying and locating adjusts cable guide pipe 6 with anchor plate 7 to design position, ensures cable guide pipe 6 by efficiently accurately positioning Accurate installation.
Certainly the above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow be familiar with technique People can understand the content of the present invention and implement it accordingly, it is not intended to limit the scope of the present invention.It is all according to this hair The modification that the Spirit Essence of bright main technical schemes is done, should be covered by the protection scope of the present invention.
