Background technique
Conductor spacer is mounted to the important protection gold utensil on overhead transmission line multiple fission conductor, plays and inhibits conducting wire dance
It is dynamic, prevent the important function of sub-wire flogging.
China starts to build 500kV overhead transmission line engineering since phase late 1980s, and conducting wire uses quadripartion.
So far, engineering voltage class in alternating current circuit has reached 1000kV, and DC line engineering has reached ± 1100kV, conducting wire division
Number has reached eight divisions.
In general, voltage class is high, the route more than division number, circle diameter where sub-conductor is relatively large, the interval used
Stick size and quality increase accordingly, and such as circle diameter reaches 1437mm where ± 1100kV route sub-conductor, and conductor spacer weighs more than 40 thousand
Gram.
Because the installation of multiple fission conductor conductor spacer is without positioning tool, mainly with personal sky when operating personnel's installation interval stick
Between judgement determine the installation site of conductor spacer claw, when leading to the acceptance of work, conductor spacer, which often exists, to lean forward or swings back, or
It takes a step (i.e. left and right is twisted) or adjacent the same set of conductor spacer is not installed on problem on same plane as required, do not meet and apply
Work and acceptance specification requirement, need reworked processing.
According to statistics, find that conductor spacer installs not positive up to 3.6% when certain ± 800kV line construction bid section acceptance,
Find that conductor spacer installs not positive up to 7.5% when certain ± 1100kV route acceptance.
Utility model content
The purpose of this utility model is to provide it is a kind of it is simple and efficient to handle, accuracy is high, it is ensured that conductor spacer installation
Primary pinpoint tool.
Positioning tool when this overhead transmission line multiple fission conductor conductor spacer provided by the utility model is installed, including
The semicircle crimping of positioning plate and positioning plate one end, the diameter of semicircle crimping is vertical with positioning plate, and the length of positioning plate is greater than
With the spacing of mutually adjacent sub-conductor, it is equipped on positioning plate and the vertically arranged laser alignment device of semicircle crimping.
In a kind of embodiment of above-mentioned technical proposal, have on the outside of the semicircle crimping parallel with the positioning plate
Flanging.
In a kind of embodiment of above-mentioned technical proposal, the laser alignment device is the laser alignment device of green light.
In a kind of embodiment of above-mentioned technical proposal, laser range finder is also equipped on the positioning plate.
It is disposed with along its length in a kind of embodiment of above-mentioned technical proposal, on the positioning plate described for installing
The mounting hole of laser alignment device and laser range finder.
This tool construction is simple, and one piece of sheet metal forming can be used, and only need to guarantee that semicircle crimping is vertical with positioning plate.This
Tool is easy to use, accurate positioning, first passes through laser range finder and determines time span, makes a root of semicircle crimping with the 1st phase
Conducting wire is close to, and is marked at positioning plate and sub-conductor contact point, rotation tool contacts positioning plate with adjacent sub-conductor, is connecing
It marks on contact, and so on label can be made on same mutually other sub-conductors, that is, can guarantee these labels in same flat
Face, so can guarantee conductor spacer structural plane perpendicular to bundle conductor when each claw of conductor spacer is mounted on these labels.Work as needs
By adjacent phase line conductor spacer with installation interval stick is in same plane when, first pass through and be spaced on the other phase conductors of laser alignment device
The installation site of stick marks the installation site of each pawl of conductor spacer referring next to aforementioned operation on sub-conductor.This tool uses model
It encloses extensively, voltage class can be met for exchange 500kV~1000kV, direct current ± 500kV~± 1100kV quadripartion, six divisions and eight
Division, diameter 47.85mm, conducting wire total sectional area 1350mm2And with the conductor spacer positioning on lower wire.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one preferred embodiment of the utility model.
Fig. 2 is the schematic top plan view of Fig. 1.
Specific embodiment
As shown in Figure 1 and Figure 2, this disclosed in the present embodiment to be installed for overhead transmission line multiple fission conductor conductor spacer
When positioning tool, the semicircle crimping 2 including 1 one end of positioning plate 1 and positioning plate is equipped with laser alignment device 3 on positioning plate 1
It (is not drawn into figure) with laser range finder.
The present embodiment uses one piece of aluminium alloy plate molding making, and the shape of aluminium alloy plate is determined as to be similar to measuring tool
30 ° of right angle triangles, and preferably plate thickness is the aluminium alloy plate of 3mm, structure is simple, and it is light-weight, although note that the width of its short right-angle side
Degree need to consider the size of semicircle crimping 2.
After right angle trigonometry board size is selected, processing is for installing laser alignment device and laser range finder in its long right-angle side
Mounting hole, the scale that can be used for linear measure longimetry is engraved in its bevel edge, its short right-angle side is curled into semicircular arc, is guaranteed simultaneously
There is the flanging parallel with triangle plate body on the outside of semicircle crimping, the setting of flanging is more conducive to jail of this tool on sub-conductor
Gu suspension.After molding, triangle plate body is positioning plate 1, and long right-angle side can be used as scale as positioning marking side, bevel edge
Ruler can use when needed.
The present embodiment working principle are as follows: two right-angle sides of right angle triangle are mutually perpendicular to, and short right-angle side is curled into circular arc
After shape, long right-angle side is tangent with circular arc portion.It is interior when circular arc portion inner wall is close to sub-conductor, between conducting wire circumference and circular arc
Relationship is cut, because long right-angle side is perpendicular to conducting wire.
This tool is before use, laser range finder and laser alignment device are separately mounted on corresponding mounting hole.
In order to which the laser for issuing laser alignment device can be also clearly apparent in fine day, so the present embodiment selects green light
Laser alignment device.
This tool use process is as follows:
1, conductor spacer time span is measured by laser range finder on the 1st phase conductor, determines conductor spacer installation site；
2, the installation site of each claw of conductor spacer is determined using this tool: intending installed position in a phase conductor conductor spacer,
Semicircle crimping is hung on a root conducting wire, and is close to semicircle crimping inner wall with the sub-conductor, long right-angle side with lead
Line contact point marks 1, and rotation tool contacts long right-angle side with adjacent sub-conductor, marks 2 at contact point；
According to said method successively made on same mutually other sub-conductors label 3,4 ..., then these labels are in same plane；
When each claw of conductor spacer is mounted on these labels, conductor spacer structural plane is perpendicular to wire harness.
3, when need by adjacent phase line conductor spacer with installation interval stick be in same plane when, first use laser alignment device
3 indicate the installation site of conductor spacer on other phase conductors, determine that the 2nd phase, the 3rd phase are led using tool referring next to preceding method
The installation site of each claw of line conductor spacer.
4, it repeats the above steps, next group of conductor spacer is installed.
