The refolded stayguy guard against theft pipe in the invention has the technical effects that the refolded stayguy guard against theft pipe is connected with a refolded stayguy in a crimping mode; and the refolded stayguy guard against theft pipe is beautiful and firm, has small possibility of being damaged, never rusts and has long service life.

Description

Refolded stayguy guard against theft pipe and preparation method thereof

Technical field

The present invention relates to a kind of anti-theft pipe, relate in particular to a kind of Refolded stayguy guard against theft pipe and preparation method thereof.

Background technology

Because China's electric line (500kV and following circuit) uses concrete bar and the steel tower (accounting for 60%～70% left and right of total shaft tower radix) with bracing wire in a large number, and the permanent uniform stressed of bracing wire is to ensure the firm key guarantee of shaft tower, once bracing wire unbalance stress or bracing wire occur to come off, can there is the serious accident of falling bar in 90% probability, thereby jeopardize the safety of electrical network and the person, therefore the most important thing of the fixing operation and maintenance work that is always electric line of pull-back wire line.In the past, fixing general galvanized wire colligation (10# iron wire) and the explosion pressure type aluminium hydraulic pressed connecting pipe of adopting of pull-back wire line, it has following shortcoming:

1, use iron wire colligation: on market, be difficult to now find processing and zincincation to meet the iron wire of national production standard completely, most iron wire zincincations is poor, make iron wire level get rusty easily (will start corrosion in 15 days after general colligation), and for anticorrosion, just need brush asphalt varnish to iron wire every one or two years, increase maintenance workload.

If 2, the iron wire of corrosion anticorrosion mopping not in time, the main line of the as easy as rolling off a log corrosion bracing wire of its corrosion layer (iron oxide), accelerates the corrosion of main line, thereby affects the stability of the normal stressed and shaft tower of bracing wire.

3, because the general phosphorus content of iron wire of the sale on market is higher, make iron wire too hard, and want lashing iron wire, by instrument (as cutting pliers etc.), in the process of operation, will inevitably destroy the zinc coat of iron wire, thereby accelerate the corrosion situation of iron wire again.

4, the process of tie wire is required great effort very much, after general 5 returning lines of the continuous colligation of personnel, arm and finger there will be the stronger phenomenon of aching, and the more difficult colligation of some employees of Xin Ru factory, there is no the exercise of one or two years, be difficult to meet completely technological standards, therefore waste time and energy with iron wire binding pulling wires returning line, require also higher to personnel's technical ability.

5, due to iron wire colligation, as easy as rolling off a log dismounting, in part outskirts of a town and rural area, often there is tie wire destroyed, the outside destroy event that pull-back wire line is cut off, according to electric company's statistics, the bracing wire of changing because returning line is destroyed every year reaches 500 more than, accumulative total expense reaches more than 80,000 yuan, brings great difficulty to the operation and maintenance of electric line.

6 and use explosive pressure pipe crimping pull-back wire line, due to explosion crimping, the manufacture craft of explosive payload and explosive pressure pipe is had to extremely strict requirement, often there is the defective and phenomenon of detonation pressure again of detonation pressure, because explosive charge has increased the potential safety hazard to human body and equipment, limitation management according to China to civil blast, this type of technique exits each electric company already.And pull-back wire line expense of drawing of this explosive pressure pipe crimping reaches more than 30 yuan of RMB, Shi Ge electric company is all difficult to bear, and therefore, is not also adopted by each electric company.

Summary of the invention

The object of the present invention is to provide a kind of Refolded stayguy guard against theft pipe and preparation method thereof, for fixing of electric line pull-back wire line, thereby make bracing wire avoid the corrosion main line that gets rusty easily causing with iron wire colligation to affect the normal stressed and easily destroyed problem of returning line of main line.

The present invention is achieved like this, it comprise " " type anti-theft pipe, it is characterized in that the wide strip aluminium sheet of 60-100mm be folded to form " " type anti-theft pipe.

Its preparation method is:

1) the little aluminium block that 5052 aluminium alloy plates that are first 3mm by thickness are cut and are pressed into that 60-100mm is wide, length and all kinds of bracing wire model adapt;

2) aluminium sheet flanging: first put into edge mould and carry out four sides bevelling cutting the little aluminium sheet pressing, at 45 °;

3) suppress half-formed pipe: the little aluminium sheet that presses limit is put into half-formed mold pressing and divide pressing mold, little aluminium sheet is struck out " " type;

4) stamped fluid pressure pipe semiproduct: by good punching press " " the half-formed pipe of type puts into semiproduct mould, strike out " " type anti-theft pipe.

Technique effect of the present invention is: adopt Refolded stayguy guard against theft pipe crimping pull-back wire line, attractive in appearance firm again, be not easy destroyed, Never-rusty, long service life.

Brief description of the drawings

Fig. 1 is structural representation of the present invention.

In the drawings, 1, " " type anti-theft pipe.

Detailed description of the invention

As shown in Figure 1, the present invention is achieved like this, it comprise " " type anti-theft pipe 1, it is characterized in that the wide strip aluminium sheet of 60-100mm be folded to form " " type anti-theft pipe 1.Returning line in bracing wire be inserted in together with on main line " " type anti-theft pipe 1, finally utilize hydraulic tongs will " " to be firmly crimped on bracing wire (main line and returning line) upper for type anti-theft pipe 1, makes bracing wire can keep stressed for a long time, avoids occurring returning line by the phenomenon of artificial destruction.

Its preparation method is:

1) the little aluminium block that 5052 aluminium alloy plates that are first 3mm by thickness are cut and are pressed into that 60-100mm is wide, length and all kinds of bracing wire model adapt;

2) aluminium sheet flanging: first put into edge mould and carry out four sides bevelling cutting the little aluminium sheet pressing, at 45 °;

3) suppress half-formed pipe: the little aluminium sheet that presses limit is put into half-formed mold pressing and divide pressing mold, little aluminium sheet is struck out " " type;

4) stamped fluid pressure pipe semiproduct: by good punching press " " the half-formed pipe of type puts into semiproduct mould, strike out " " type anti-theft pipe.
